The design concept, basic design and tuning procedures are discussed. The important features of the interferometer, i.e. compactness, versatility, polarization insensitivity, relaxed collimation requirements, low laser power and remote optics, are addressed. Several such interferometers have been constructed and successfully applied to engineering problems. These include examining the displacement fields surrounding drilled and preformed holes in composite laminates loaded in tension, and the evaluation of nonhomogeneous behavior in textile composites.

Scanning optical array generators would facilitate the alignment of optical interconnect architectures and could provide a critical technology for the implementation of parallel addressing schemes in three-dimensional optical memories. A three-port implementation of a PLZT-based scanning optical array generator is presented. The three-port implementation offers a significant reduction in the maximum electrode voltage required to effect a specific scan angle.

Specifically, we consider a singly resonant optical parametric oscillator (OPO) containing an intracavity second-harmonic generator (SHG) for doubling the OPO signal frequency. We determine the stable steady states that completely deplete the incident pump radiation. Phase mismatch in the SHG process is considered. An example of converting 532 nm radiation to 365 nm radiation is discussed; power conversion efficiency as high as 63% is predicted. C1 UNIV NEW MEXICO,CTR ADV STUDIES,ALBUQUERQUE,NM 87131.

The resulting matrix-vector equations describing the optimal solution can be very easily implemented on say an IBM PC running Matlab or MatrixX on the one hand and have standard parallel solution methods for implementation on parallel computers on the other. Some computational results performed on an Intel hypercube are presented to illustrate that considerable computational savings can be realized by using the proposed algorithm.

Specimens from a Ni-22.9 at.% Al single crystal, having an orientation near (001), were pre-strained at 873 K and additionally strained at 300 K. The flow properties of this crystal were compared to those from a crystal strained at 300 K alone. Both crystals were examined using transmission electron microscopy. In the small-strain flow regime, the flow stress anomaly is reversible. Pre-straining at a higher temperature before room-temperature deformation shows little memory of the pre-straining during the yield transient, even though TEM observations show that many Kear-Wilsdorf locks are retained in the substructure. Microscopic examination also reveals the presence of a second dislocation structure, characteristic of the low-temperature deformation, in selected regions of thin foils from the pre-strained sample. This observation demands that some part of the substructure recovers extremely rapidly, if not instantly upon changing temperature and (or) unloading. We suggest that future models must consider the full behaviour of all dislocation loop characters and character junctions in accomplishing the thermally reversible transition from the elastic regime, through the microstrain regime, to flow.

Local hypoxia may become self-reinforcing, as hypoxic cells block capillaries preventing perfusion by oxygenated cells. Hyperbaric oxygen (HBO) is frequently used to treat conditions involving some degree of local hypoxia, but does it have a direct effect on deformability? To investigate this, 12 normal dogs received a 10 week ''clinical'' course of HBO: one 90 min treatment per weekday at 2.4 ATA (243 kPa), 100% O-2. On Mondays and Fridays, a blood sample was drawn into EDTA, centrifuged, and the packed red blood cells resuspended in medium to a dilution of 2x10(6) to 5x10(6) cells/ml, and filtered under constant pressure of 1.08 kPa through a precalibrated Nuclepore Hemafil Polycarbonate membrane. Filtrate was collected for one minute and weighed, and the red blood cell ''incremental volume'' calculated according to Engstrom (Engstrom and Ohlsson, Pediatric Res. 27:220-226, 1990). No significant change was seen in filtration rates, indicating that HBO itself neither improves nor impairs dog red blood cell deformability. Changes in other commonly measured blood parameters remained within clinical norms. An acute fluid shift out of red blood cells and into plasma was indicated.

Experimentally determined values by EFISHG show that reasonably large values of the first hyperpolarizability beta can be obtained with a much larger transparency window than normally demonstrated by convential chromophores with comparable beta values. The dipole moments of these molecules can be controlled independently from beta. These types of chromophore molecular structures can be incorporated into acetylene-terminated thermoset monomers which when incorporated into thin films of high Tg thermoplastics can be cured to produce composite films with stable second-order activity at 100 degrees C.

The study area was divided into 3 units and 1 was burned each year. Grasshopper sparrow population density was related to the 3 burn regimes: <1 year post-burn, 1-2 years post-burn, and >2 years post-burn. Grasshopper sparrows did not utilize each burn regime in proportion to its occurrence (X-2 = 21.86, df = 2, P < 0.001). Grasshopper sparrows preferred areas <1 year post-burn, avoided areas >2 years post-burn, and used the intermediate burn regime in proportion to its occurrence (P < 0.01). Grasshopper sparrows did not colonize areas of apparently suitable habitat that were spatially separated from the population by areas of unsuitable habitat. Recommendations for burning grasshopper sparrow habitat are presented. This study also suggests that experimental reintroduction of grasshopper sparrows into unoccupied habitat may be appropriate.

The data consist of records of ionospheric total electron content (TEC) from a number of passes of the U. S. Navy Navigation Satellite System spacecraft over a chain of ground-based receiving stations. Data collection and reduction techniques are discussed; these include the determination of absolute TEC from the different phase advances induced by the ionosphere in each component of the dual-frequency spacecraft signal. The use of tomographic methods to reconstruct ionospheric electron densities over a two-dimensional (2-D) region of the Earth's ionosphere at a number of different times is demonstrated. Specifically, two distinct tomographic methods, the algebraic reconstruction technique and a maximum entropy method, are used to mathematically invert the records of TEC. The resulting 2-D contour ''maps'' of ionospheric electron density are then compared to similar maps produced by the Millstone Hill incoherent backscatter radar facility located at Westford, Massachusetts. Both qualitative and quantitative measures of agreement among the different reconstructions and the radar maps are presented. The behavior of the ionosphere over the course of the experiment is discussed. C1 MIT,HAYSTACK OBSERV,ATMOSPHER SCI GRP,WESTFORD,MA 01886. BOSTON COLL,INST SPACE RES,NEWTON,MA 02159.

In current practice, this spatial design process is very labor-intensive and expensive. This paper describes a prototype CAD system which models design decision-making, providing a computable framework for automation. The CAD system performs auto-elicitation of an expert's judgment in the form of fuzzy sets using interactive computer graphics. These fuzzy sets are then used in a heuristic search process employing multi-objective, non-linear optimization. Designs synthesized by this fuzzy CAD system are comparable to those generated ''by hand,'' and in some cases exceed a practitioner's design in quality. The CAD system, as presently constructed, provides multiple solutions. Conclusions and recommendations regarding processing speed and unrepresented heuristic content are made.

The authors consider the generalization of the PG algorithm to signals in the wavelet subspaces in this research. The uniqueness of the extrapolation for continuous-time signals is examined, and sufficient conditions on signals and wavelet bases for the generalized PG (GPG) algorithm to converge are given. A discrete GPG algorithm is proposed for discrete-time signal extrapolation, and its convergence is investigated. Numerical examples are given to illustrate the performance of the discrete GPG algorithm. C1 UNIV SO CALIF,INST SIGNAL & IMAGE PROC,DEPT ELECT ENGN SYST,LOS ANGELES,CA 90089.

Unlike the case in undoped AlGaAs/GaAs, strong Shubnikov-de Haas oscillations were observed in this structure after increasing the carrier concentration via the persistent photoconductivity effect. Low temperature mobilities close to 70000 cm(2) V-1 s(-1) at a carrier concentration of 6.5 x 10(11) cm(-2) were observed in a 25 Angstrom quantum well. The results are compared with the theory of interace roughness scattering and we find that the mobility of our samples goes as L(1.3) where L is the well width. We conclude that the barrier height of the confining potential plays a very important role in determining the effect of interface roughness scattering on the mobility of very thin quantum wells.

The two-dimensional electron gas was studied by low field Hall and Shubnikov-de Haas measurements. Both the low field mobility and quantum scattering time increased with increasing carrier concentration after illumination with red light. The increase in carrier concentration is attributed to photoexcitation of carriers from a deep level located at 0.9 eV below the conduction band of InGaP. Parallel conduction due to extended illumination has also been observed in the anomalous behavior of the quantum Hall plateaus.

The spectral response occurs at shorter wavelength than originally expected. Detailed experimental analysis has determined that the valence band well is quite deep. This has been confirmed by theoretical analysis using an 8 band envelope function analysis (EFA). The spin splitoff is small in the barrier material compared with the depth of the valence band well. The combined effect of a deep well and a small splitoff results in the observed spectral shape. The influence of the splitoff band on photoresponse is insignificant for GaAs/AlxGa1-xAs systems with x approximate to 0.03 C1 WRIGHT LAB,MAT DIRECTORATE,WL MLPO,WRIGHT PATTERSON AFB,OH 45433.

The effect of layer widths, indium content, buffer choice, substrate orientation, interface type, layer growth order, piezoelectricity, and layer width variations on the cutoff wavelength and the linear absorption coefficient is investigated. We propose specific superlattice parameters that optimize absorption for superlattices grown on GaSb at three cutoff wavelengths. C1 UNIV ALABAMA,CTR APPL OPT,HUNTSVILLE,AL 35899.

Solutions to the governing equation are derived for one-dimensional flow with boundary conditions corresponding to an impervious (conventional no-flow boundary), a partially drained boundary, and a partially drained boundary with an intervening permeable zone between the boundary and the soil. These latter two boundary conditions can arise from details of pore pressure measuring systems at the specimen boundaries during laboratory experiments. An analysis of the solutions indicates that for a perfect no-flow boundary, excess pore pressures measured at an electrode consist of a steady state and rapidly-decaying transient response. The pore pressures exhibit a 45 degree phase shift relative to the applied electric current. The effect of the partially drained boundary is to reduce the peak to peak amplitude of the pore pressure and to increase the phase shift to as much as 90 degrees depending on the compressibility of the pore pressure measuring system. The effect of the impeded and partially drained boundary is to further reduce the amplitude of the pore pressures and to increase the phase shift to as much as 180 degrees depending on the relative permeability of the impeded boundary.

A ball-on-flat apparatus, in which a 440C stainless steel ball was held on a rotating dish coated with a WS2 film, was used as the test configuration. Friction measurements were made in dry nitrogen and in laboratory air. Wear surfaces were characterized by scanning electron microscopy and Raman spectroscopy. The friction coefficient of the film in dry nitrogen was 0.04, and in laboratory air it rose to between 0.10 and 0.15. In the dry nitrogen case, friction induced some degree of crystallinity into the otherwise amorphous film, while rubbing in air mostly resulted in oxidation of the film. Transfer films formed in a dry environment were smooth, tenacious and firmly adherent to the steel counterface. By contrast, the films formed in air were patchy and powdery in nature.

It is shown that for small concentrations of the additive in %N-2-%H-2, the effects on the discharge impedance are diagnostic probes providing crucial information regarding the dissociation and ionization balances. The results show that for low discharge currents (<80 mA), medium gas pressures (>1 Torr), and approximate to 10%-80%H-2-N-2 mixture composition, collisions between excited electronic states of N-2 with H-2 are the dominant dissociation channels of H-2 in %H-2-%N-2 discharges.

THEORY SO JOURNAL OF PHYSICAL CHEMISTRY LA English DT Article AB The interlayer space of fixed-charge, expandable, layered aluminosilicate clays is considered filled with a two-component dielectric solution and treated as an open thermodynamic system. The composition of the interlayer solution, relative to the external solution, is obtained by performing a thermodynamic analysis that includes the work of polarization of the dielectric solution. The theory predicts that compositional changes are most dramatic when the component having greater polarity is present to a smaller extent (less than or equal to 20 mol %). Furthermore, the theory is shown to contribute significantly to the understanding of previously published adsorption isotherm data as well as swelling behavior of organo-clays in organic solvents.

EXPERIMENT SO JOURNAL OF PHYSICAL CHEMISTRY LA English DT Article ID SORPTION AB FT-IR spectroscopy is used to directly measure the composition of the sorbed phase on a charged, expandable organo-montmorillonite placed into contact with binary solvent solutions. Experimental data are compared with thermodynamic computations of the sorbed phase composition. The theoretical treatment, developed in part 1, examines the extent of partitioning due to electrical charging of the clay-water interface which is in addition to any partitioning that might result from purely chemical differences between the interlayer environment of layered aluminosilicate clay minerals and an external solution. Provided the extent of partitioning is expected to be large, as it is for the acetone-toluene system, the agreement between theory and experiment is very good. On the other hand, as the predicted extent of partitioning becomes smaller, the agreement between theory and experiment degrades. In addition to composition measurements, the magnitude of the interfacial electric field is characterized by examination of the carbonyl stretching frequency of acetone, which is common to all three solvent combinations studied. As the component of smaller dielectric constant is displaced, the carbonyl stretching frequency is observed to rise. This is expected since an increased dielectric constant will reduce the electric field and thereby favor the nonpolar form of acetone with its higher stretching frequency. The implications of our results to electrical double-layer theory, which treats the dielectric constant as spatially fixed, are briefly discussed.

Structural properties were studied as a function of contact composition, by transmission electron microscopy and scanning electron microscopy, in addition to other techniques. In all cases, Al was deposited as the top layer at a fixed thickness. While all metallizations exhibit a non-spiking interface with the GaAs substrate, it was found that the contact morphology varies strongly with the Ge:Ni thickness ratio. For a Ge:Ni thickness ratio of 3:4 or greater, annealing results in the formation of a thick Al3Ni layer adjacent to the GaAs substrate, as well as a non-uniform surface layer, characterized by dendritic Ge precipitates in an Al matrix. By lowering the Ge:Ni thickness ratio to 1:2, the surface morphology was greatly improved and the contact displays a stable layered structure of the type Al3Ni/(Ni-Ge)/GaAs. These results were accounted for on the basis of a recently developed Al-Ni-Ge ternary phase diagram. C1 USAF,WRIGHT LAB,MAT DIRECTORATE,WRIGHT PATTERSON AFB,OH 45433.

Addition of exogenous recombinant ''type 1'' lymphokines interferon gamma and interleukin 2 (IL-2), as well as the macrophage-produced IL-12, which favor cell-mediated T-cell responses, blocks both systems of T-lymphocyte programed cell death. In contrast, the ''type 2'' lymphokines IL-4 and IL-10, which favor antibody responses, either had no effect or enhanced these systems of in vitro T-cell programed cell death. A role for endogenously produced cytokines was suggested by the inhibition of T-cell receptor-mediated death by antibodies against IL-4 and IL-10 and its enhancement by anti-IL-12 in cultures containing monocytes. These results demonstrate that the functional properties of type 1 and type 2 cytokine classes may be further extended to include their effects on T-cell programed cell death and their possible role in the pathogenesis of HIV infection.

The siloxanes containing up to 20% spiropyran are liquid crystalline, whereas at higher compositions the products are amorphous. With increasing spiropyran content, the selective reflection band characteristic of the cholesteric mesophase shifted to lower wavelengths. The photochromic reaction leading to the blue merocyanine formation resulted in a narrowing of the reflection bandwidth. Steric effects imposed by cholesterol, biphenyl, and bulky spiropyran groups dominate the thermal decoloration kinetics of the merocyanine form. Aggregation of merocyanines was observed in nonpolar solvents, whereas in thin glassy films formed by shearing in the liquid crystalline state such an observation was not evident. In siloxanes bound only to spiropyran, an evidence of a shift in the thermal equilibrium toward merocyanine aggregate formation leading to molecular stacks was observed. Short spacer length of the leader group in spiropyran inhibited 100% attachment to the cyclic siloxane backbone, possibly due to steric effects. Longer spacer groups facilitated 100% attachment.

From 1987 to 1993, we performed 504 consecutive infrainguinal vein bypass grafts, of which 56 (11%) originated from the popliteal artery, 25 above and 31 below the knee. PATIENTS AND METHODS: The patients were 16 women and 37 men, with a mean age of 62.4 years. Eighty-seven percent were diabetic, 57% had clinically obvious coronary artery disease, and 28% had end-stage renal disease (ESRD). The indication for surgery was ulceration or gangrene in 93% of cases. We preferentially used reversed greater saphenous vein harvested from the thigh to optimize conduit quality and avoid lower leg wound complications. The outflow artery sites were: dorsal pedal (17), posterior tibial (14), peroneal (10), anterior tibial (8), lateral or medial plantar (5), and sequential tibial (2). All patients were followed postoperatively with serial duplex surveillance. The mean follow-up was 12.5 months (range 1 to 66). RESULTS: In-hospital mortality was 5.4%. Mortality at 24 months was 19% overall and 38% in patients with ESRD. Limb salvage Tvas 77% at 3 years, 92% in patients with normal renal function versus 59% in those with ESRD (P<0.003). Primary graft patency by life-table analysis was 94% at 1 month and 84% at 3 years. Five patients with patent grafts required amputation, 4 early and 1 late. Eight months after surgery, 1 patient (1.8%) developed superficial femoral artery stenosis which was diagnosed by duplex surveillance and successfully treated by percutaneous transluminal balloon angioplasty. CONCLUSIONS: Vein bypass grafts originating from the popliteal artery are effective and durable. Proximal disease progression rarely poses a significant threat to long-term graft patency. Patients with ESRD, blind tibial outflow tracts, and extensive forefoot lesions appear to be at increased risk of limb loss even,vith continued graft patency.

METHODS: Arteriograms were reviewed to characterize the anatomy of the infrapopliteal arterial runoff. Regular clinical evaluation and prospective serial duplex scan surveillance assessed graft patency. RESULTS: A total of 28 patients underwent 45 popliteal aneurysmorrhaphies. Elective repair was performed in 32 limbs (71%); emergency treatment was needed for 13 limbs (29%) because of acute limb-threatening ischemia. All patients were managed with PAA exclusion and reversed saphenous vein grafting. Only 20 limbs (44%) had a patent trifurcation with three continuous vessels to the ankle, 13 (29%) had two continuous tibial vessels, 10 (22%) had one patent runoff artery, and 2 (4%) had no vessel continuous to the foot. With a mean follow-up of 19.1 months, the 5-year primary graft patency by life-table analysis was 95 +/- 12.3%, with a 5-year assisted primary patency of 97 +/- 10.0%. One vein graft underwent elective secondary revision. Another graft thrombosed, requiring a secondary bypass Outcome did not correlate with the status of the runoff anatomy. Limb salvage was 100%. CONCLUSION: The use of autologous reversed vein grafting and attention to technical details yielded normal graft hemodynamics and excellent long-term patency and limb salvage despite the suboptimal runoff anatomy associated with PAAs.

Design: Prospective, randomized, double-blinded human protocol. Setting: Urban Level I military emergency department. Participants: Fourteen adult volunteers who took no routine medications, were not pregnant, had no known sensitivity to naloxone, and who were negative for a pretest urine and serum toxicologic screen. Interventions: We administered either 2 or 4 mg IV naloxone to 14 subjects. Urine drug screening was obtained before administration and at 60 minutes, 6 hours, and 48 hours after administration. Results: All urine drug screens using the enzyme-multiplied immunoassay technique were negative for opiates at both dosage levels. The sample size of 14 yielded a power of more than .99 to detect the difference between positive and negative samples. Conclusion: Although the metabolities of naloxone hydrochloride are similar in structure to oxymorphone and are excreted in human urine for several days, naloxone was not associated with a positive enzymatic urine screen for opiates.

Demographic change played a large role in the military capacity to maintain itself as a dramatic influx of family members during the 1960s and the need to maintain a large volunteer force, in synergy with a strong tradition of spouse volunteerism, led to the development of the family center system. The military's relationship with its families from 1775 to 1993 has been characterized by several trends: from neglect to concern; from informal mechanisms and an implied obligation to a formal, institutionalized policy response; and from locally determined, ad hoc, reactive measures to comprehensive, federally funded, planned services. As work and family boundaries shift, both the military and private corporate sectors are examining ways to better accommodate the needs of both family and workplace through programmatic and policy initiatives.

Average VA's using ANVIS (Snellen = 20/38, Grid = 20/45) were significantly better (p < 0.01) than VA's using AN/ PVS-5 (Snellen = 20/54, Grid = 20/58). Snellen VA's were better on average than Grid VA's (p < 0.001). Neither age, gender, nor NVG experience affected average VA at the 0.05 level. Average VA was significantly better (p < 0.05) for non-spectacle wearers using ANVIS goggles and for non-smokers using AN/PVS-5 gaggles. Visual acuity is better with ANVIS than with AN/PVS-5 goggles, and may be affected somewhat by wearing spectacles, and by smoking, C1 USAF,SCH AEROSP MED,BROOKS AFB,TX 78235.

The ability to predict such effects for realistic exposure scenarios would greatly improve OP risk assessment. To this end, a physiologically based model for diisopropylfluorophosphate (DFP) pharmacokinetics and acetylcholinesterase (AChE) inhibition was developed. DFP tissue/blood partition coefficients, rates of DFP hydrolysis by esterases. and DFP-esterase bimolecular inhibition rate constants were determined in rat tissue homogenates. Other model parameters were scaled for rats and mice using standard allometric relationships, These DFP-specific parameter values were used with the model to simulate pharmacokinetic data from mice and rats. literature data were used for model validation. DFP concentrations in mouse plasma and brain, as weil as AChE inhibition and AChE resynthesis data, were successfully simulated for a single iv injection. Effects of repeated, subcutaneous DFP dosing on AChE activity in rat plasma and brain were also well simulated except for an apparent decrease in basal AChE activity in the brain which persisted 35 days after the last dose. The psychologically based pharmacokinetic (PBPK) model parameter values specific for DFP in humans, for example. tissue/blood partition coefficients, enzymatic and nonenzymatic DFP hydrolysis rates, and bimolecular inhibition rate constants for target enzymes were scaled from rodent data or obtained from the literature Good agreement was obtained between model predictions and human exposure data on the inhibition of red blood cell AChE and plasma butyrylcholinesterase after an intramuscular injection of 33 mu g/kg DFP and at 24 hr after acute doses of DFP (10-54 mu g/kg), as well as for repeated DFP exposures. The PBPK model for DFP was also adapted for the purpose of modeling parathion, including its metabolism to the toxic daughter product paraoxon. The development and validation of this PBPK model for two OPs provides a basis for studying the kinetics and in vivo metabolism of other bioactivated organophosphate pesticides and their pharmacodynamic effect in humans.

Several authors have speculated that human responses to thermal stress reflect AVHT in the head and neck, even though primates lack the specialized vascular arrangements which characterize AVHT in other animals. We modeled heat transfer based on the anatomical relationships and blood flows for the carotid artery and associated venous channels in the human neck and cavernous sinus. Heat transfer rate was predicted using the ''effectiveness-number of transfer units'' method for heat exchanger analysis. Modeling showed that AVHT is critically dependent upon (1) heat exchanger effectiveness and (2) arteriovenous inlet temperature difference. Predicted heat exchanger effectiveness is less than 5.5% for the neck and 0.3% for the cavernous sinus. These very low values reflect both the small arteriovenous interface for heat exchange and the high flow rate in the carotid artery. In addition, humans lack the strong venous temperature depression required to drive heat exchange; both the cavernous sinus and the internal jugular vein carry a large proportion of venous blood warmed by its passage through the brain as well as a small contribution from the face and scalp, whose temperature varies with environmental conditions. Under the most optimistic set of assumptions, carotid artery temperature would be lowered by less than 0.1 degrees C during its passage from the aorta to the base of the brain. Physiologically significant cooling of the blood supply to the brain cannot occur in the absence of a suitably scaled site specialized for heat exchange. C1 ARMSTRONG LAB,SAN ANTONIO,TX 78235.

In the present study, representations of teamwork knowledge as a function of team experience were investigated. Teamwork knowledge structures, or teamwork schemas, were assessed using multidimensional scaling and ''freehand'' concept maps. Consistent with contemporary expert-novice literature, the results revealed that higher experience team members conceptualized teamwork more concisely and in more abstract terms than did lower experience team members. In addition, results from the two methodologies converged to a greater degree for higher experience individuals than for lower experience individuals suggesting that higher experience individuals can express consistently what they understand about teamwork. The results suggested that team training should be designed based on trainees' prior team experiences and teamwork knowledge. Team managers might also keep in mind potential team members' experience levels when making team assignments. C1 USAF,HUMAN RESOURCES LAB,WRIGHT PATTERSON AFB,OH 45433.

The model is developed from a knowledge of device make-up (doping concentrations, layer thicknesses etc.), and relevant physics (such as the effects of graded heterojunction, self-heating, thermal coupling and ballast emitter resistance) is included in a unified manner. Thermal runaway phenomenon observed in the multifinger HBT at high current levels has been successfully described. Experimental evidence obtained from six-finger and four-finger HBTs are included in support of the model. The thermal runaway phenomenon is caused by the uneven increase of the base and collector currents at elevated temperatures due to the thermal effect.

The introduction rate of most defects is a strong function of applied bias and distance from the junction. Open circuit irradiation produces the smallest introduction rate while reverse bias enhances the rate by a factor of five for most defects. The C-V technique finds three times the concentration of defects that the DLTS technique finds. The C-V technique cannot distinguish types of defects: it sums all defects. Heavy reverse bias irradiations produced unstable junctions that could be partially restabilized by further opera circuit irradiations. The electron-hole pairs generated by the irradiation appear to play a major role in the development of the final defect population resulting from the same irradiation. Even in a short irradiation, defects initially created early in the irradiation are altered or annealed by continued irradiation. Recombination-enhanced diffusion theory appears to explain some of the results and, therefore, may be an important factor in the defect introduction process in many semiconductors.

Spectra with end-point energies ranging from 20 to 160 keV were recorded. A separate effort to calibrate the dosimetry for the Phillips Laboratory low-energy x-ray facility established a need to know the spectral energy distributions at some point within the facility (previous calibration efforts had relied on spectra obtained from computer simulations). It was discovered that the primary discrepancy between the simulated and measured spectra was in the L- and K-line data. The associated intensity (energy flux density) of the measured distributions was found to be up to 30% higher. Based on the measured distributions, predicted device responses were within 10% of the measured response as compared to about 30% accuracy obtained with simulated distributions.

The xray tube has a tungsten target and emits a bremsstrahlung xray spectrum with end point energies up to 160 keV. Analytical tools and experimental dosimetry techniques were developed to map the radiation field intensity and the resulting dose-deposition profiles in a variety of materials throughout the chamber. Three detector types (x-ray vacuum diodes, silicon PIN diodes, and PMOS FETs) were used to measure spectral intensity and dose deposition in silicon devices. CEPXS and PHOTCOEF electron-photon transport codes were used to calculate the incident spectral energy distribution and the energy deposition in the detector. Calculated and experimental diode detector responses agreed to within 10 percent over the full energy range. PMOS FETs were used to demonstrate the correlation between total-dose-deposited in the x-ray chamber and in the Cobalt-60 cell. The results of this effort provide dosimetry and analysis tools needed to perform ionizing radiation testing of large area (0.5m(2)) electronic subsystems.

The transistors were exposed to low energy x-rays while placed in a liquid nitrogen-cooled dewar Results demonstrate significant performance and survivability advantages for space-borne power MOSFETs operated at cryogenic temperatures. The key advantages for low-temperature operation of power MOSFET's in an ionizing radiation environment are: (1) steeper subthreshold current slope before and after irradiation; (2) lower off-state leakage currents before and after irradiation; and (3) larger prerad threshold voltage for n-channel devices. The first two points are also beneficial for devices that are not irradiated, but the advantages are more significant in radiation environments. The third point is only an advantage for commercial devices operated in radiation environments. Results also demonstrate that commercial off-the-shelf power MOSFETs can be used for low-temperature operation in a limited total dose environment (i.e., many space applications).

The C-137 exposures at 0.01 rad(SiO2)/s are two orders of magnitude lower in dose rate than any previous irradiations for this process and thus facilitate comparison to the device response in space. Low-dose-rate gain degradation exceeds high-dose-rate degradation for total doses less than 1 Mrad(SiO2), consistent with previous reports. For the first time, the gain degradation is demonstrated to be equivalent for dose rates between 0.01 and 10 rad(SiO2)/s, suggesting that the dose-rate response saturates at similar to 10 rad(SiO2)/s for the devices studied in this work. On the basis of a recent model, high-dose-rate irradiations at 60 degrees C were performed and found to be consistent with the room-temperature, low-dose-rate, saturated response. These results suggest several promising new approaches to bipolar space-qualification testing. C1 SANDIA NATL LABS,DEPT 1332,ALBUQUERQUE,NM 87185. UNIV ARIZONA,DEPT ELECT & COMP ENGN,TUCSON,AZ 85721.

Intact cells catalyze the oxidation of 2NT to 3-methylcatechol and nitrite in a reaction that requires molecular oxygen. Cell extracts oxidized 2NT to 3-methylcatechol and nitrite in the presence of NAD(P)H and ferrous iron. Ion exchange chromatography yielded three protein fractions (A, B, and C) which were all required for the oxidation of 2NT to 3-methylcatechol and nitrite. Component B (reductase(2NT)) catalyzed a NAD(P)H-dependent reduction of cytochrome c. Solutions of component A (ISP2NT) were brown and showed absorption maxima at 458 and 324 nm. Two major bands with M(r)s 52,500 and 28,000 were observed when ISP2NT was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Component C could be replaced by ferredoxin(NAP) from the Pseudomonas putida NCIB 9816-4 naphthalene dioxygenase system and was given the designation ferredoxin(2NT). Experiments with O-18(2) showed that both oxygen atoms were added to the aromatic ring of 2NT to yield 3-methylcatechol. The enzyme is a new multicomponent enzyme system which we have designated 2NT 2,3-dioxygenase. C1 UNIV IOWA,DEPT MICROBIOL,IOWA CITY,IA 52242. UNIV IOWA,CTR BIOCATALYSIS & BIOPROC,IOWA CITY,IA 52242.

Osteoblasts attached equally well to all the polymer substrates after 8 h in culture. By day 4 in culture, osteoblasts had exceeded confluency numbers, and their proliferation leveled off by day 7. An increase in alkaline phosphatase (ALP) activity from 1.92(+/-0.47) x 10(-7) for day 7 to 5.75 (+/-0.12) x 10(-7) mu mol/cell per min for day 14 was reported for osteoblasts cultured on 75:25 PLGA, which was comparable to that observed for tissue culture polystyrene (TCPS) controls. The ALP activities expressed by osteoblasts cultured on PLLA, 50:50 PLGA, and PGA films did not significantly increase over time. Collagen synthesis for osteoblasts cultured on all polymer substrates was similar to that of TCPS and did not vary with time. The morphology of cultured osteoblasts was not affected by the continuous degradation of the polymer substrates. These results demonstrate that poly(ol-hydroxy esters) can provide a suitable substrate for osteoblast culture and hold promise in bone regeneration by osteoblast transplantation.

By choosing different concentration volume ratios of citric acid to hydrogen peroxide (chi C6H8O7:1H(2)O(2)), highly selective as well as uniform (nonselective) etching regions were found to exist in these material systems. Etchant selectivities greater than 50 were found for most combinations of the III-V semiconductor materials under investigation, with selectivities of over 100 measured for GaAs/GaSb and InAs/GaSb material combinations, and with selectivities of over 3850 calculated for InAs/Al0.5Ga0.5Sb to 13,650 for GaAs/Al0.5Ga0.5Sb. The highest overall etch rates were measured for InAs and the lowest etch rates were found for Al0.5Ga0.5Sb. The etch rate for the GaAs1-xSbx materials systematically decreased from the highest etch rate for the smallest Sb mole fraction examined of GaAs0.85Sb0.15 to the lowest etch rate for GaSb. The dramatic change in etch rate with citric acid/hydrogen peroxide volume ratio previously observed for the GaAs/AlGaAs material system was also observed for GaAs0.85Sb0.15, but this effect was not seen in higher Sb mole fraction alloys of GaAs1-xSbx examined. Al0.5Ga0.5Sb and GaSb were found to have very low etch rates with this etchant system at all volume ratios, making both materials suitable as an etch stop layer for simplified processing in device fabrication. Finally, citric acid/hydrogen peroxide can be used to preferentially etch these materials through a photoresist mask, since it does not erode photoresist at any volume ratio.

Of 462 ticks involved in attacks on people, the lone star tick, Amblyomma americanum, and the American dog tick, Dermacentor variabilis, were the most common species represented (34.2% and 34.0%, respectively). Two vectors of Lyme disease, bodes pacificus and bodes scapularis (including the former Ixodes dammini) also parasitized people but were less common (1.7% and 9.1%, respectively). In addition, 34 (7.3%) brown dog ticks, Rhipicephalus sanguineus, were identified from human hosts. Most ticks submitted for identification were adults (66.5%) and nymphs (29.1%). Larvae were submitted infrequently (< 5%). Of those specimens examined for feeding status, 50.0% had blood-fed to some degree. Patients from which ticks were removed were predominantly male (56.8%) and ranged in age from 1 to 76 years with 55.3% (n = 152) being under 20 years. The head and neck area and the lower extremities were the most common sites of attachment by ticks (37.7% and 24.3%, respectively), but ticks were found attached on other areas of the body also, including the trunk, upper extremities, buttocks, and groin. Most ticks (65.5%) bit their victims during May, June, or July, but parasitism occurred during all months of the year. Our data suggest that people from all age groups and from across the United States are vulnerable to parasitism by ticks and, potentially, tick-borne diseases.

The elevated electron temperature in turn causes an increased gate current. The highest electron temperature is reached at the drain. However, the gate-to-channel barrier is the highest at the drain, which decreases the electron transfer over the barrier. In this paper we investigate the dependence of the gate current on lattice temperature and drain bias, and show that at high drain and gate biases the largest contribution to the gate current comes from the region where the electron temperature, leading to the electron emission from the channel to the gate, is less than 100 degrees C larger than the lattice temperature.

Microstructures developed during canned, conventional hot forging were compared to those from isothermal hot forging. The higher rate of deformation in conventional forging led to considerably finer and almost completely broken-down structures in the as-forged condition. Several nontraditional approaches, including the isothermal forging of a metastable microstructure (so-called ''alpha forging'') and the inclusion of a short static recrystallization anneal during forging, were found to produce a more fully broken-down structure in as-isothermally forged conditions. Despite the noticeable microstructure differences after forging, conventionally and isothermally forged material responded similarly during heat treatment. In both cases, almost totally recrystallized structures of either equiaxed gamma or transformed alpha grains surrounded by fine gamma grains were produced depending on the heat-treatment temperature. Metallography on forged and heat-treated pancake macroslices was useful in delineating small differences in composition not easily detected by analytical methods.

A study was conducted to evaluate the effect of varying volume fraction of the (Mo) phase on the microstructure, bend strength, and ambient temperature fracture behavior of selected NiAl-Mo two-phase alloys. Above room temperature, the NiAl-Mo alloys showed an increase in bend strength compared to monolithic NiAl, with reasonable strength retention up to similar to 800 degrees C. The results demonstrated moderate improvements in toughness in the NiAl-Mo alloys in comparison to monolithic NiAl. A further enhancement in toughness was realized through hot working. Fractography studies showed evidence, for substantial decohesion between the (Mo) phase and the NiAl matrix, thereby suggesting the presence of a weak interface. This weak interface between the (Mo) phase and the NiAl matrix, in conjunction with modulus mismatch stresses, causes the crack to deflect from the (Mo) reinforcement and propagate preferentially along the (Mo)/NiAl interface. These attributes limit the potential for significant ductile-phase toughening in the NiAl-Mo system. An addition of 0.2 at. pct Ti resulted in a marked improvement in the room-temperature fracture toughness of NiAl-Mo. Fractography observations show some evidence for (Mo)/NiAl interface strengthening with the Ti addition. C1 USAF,WRIGHT LAB,MLLM,WRIGHT PATTERSON AFB,OH 45433.

Similarly, patentable discoveries can be made during the normal course of medical practice, e.g., the development of new biocompatible polymers, improved dental materials, new or modified catheters, new laboratory diagnostic tests, and improved medical devices. Many inventions may not be patented in federal organizations due to the lack of information available on the patenting process. In this article, the financial benefits that can be derived from patenting inventions are discussed, as well as the different types of patents that can be obtained, the conditions for patentability, bars or restrictions to obtaining a patent, the importance of proper record keeping, and the steps to take toward getting an invention patented.

We provide numerical predictions for SNR increases according to our previously developed theory. We also detail our experimental efforts and provide the results of SNR measurements for four distinct cases: direct radar detection with and without a fiber amplifier, and heterodyne ladar detection with and without a fiber amplifier. Experimentally measured increases in SNRs for ladar systems incorporating an optical-fiber amplifier are then compared with our earlier predictions. Specifically, we have found that for direct detection with a fiber amplifier in place, the predicted SNR increase is 42.0 dB, and we have measured an increase of 36.5 dB. Similarly, for heterodyne ladar detection with a fiber amplifier, the predicted SNR increase is 3.8 dB, and we have measured an increase of 8.0 dB.

A KTP crystal is used for the sum-frequency generation (SFG). Both extracavity and intracavity SFG is demonstrated, with overall conversion efficiencies of 3.5% and 10.5%, respectively. Near-transform-limited pulses of less than 50 ps are generated from 100-ps pulses. With a limited available peak pump power, both spatial orderings of the KTP and the AgGaS2 crystals for intracavity SFG produce similar conversion efficiency and outputs of similar pulse duration, spectral width, and stability.

The micromachined GC system is composed of a miniature sample injector that incorporates a 10 mu l sample loop, a rectangular-shaped (width, 300 mu m; height, 10 mu m) capillary column, with a length of 0.9 m, coated with a copper phthalocyanine (CuPc) stationary phase (thickness, 0.2 mu m) and a dual-detector scheme based on a CuPc-coated chemiresistor and a commercially available, thermal conductivity detector (TCD) bead (diameter, 125 mu m). Silicon micromachining was employed to fabricate the interface between the sample injector and the GC column, the column itself and the dual-detector cavity. A novel IC thin-film processing technique was developed to sublime the CuPc stationary phase coating on the column walls that were micromachined in the host silicon wafer substrate and the Pyrex(R) cover plate, which were then electrostatically bonded together. The CuPc-coated chemiresistor was designed and fabricated using conventional IC processing techniques. The micromachined GC system can separate parts per million (ppm) ammonia and nitrogen dioxide concentrations when isothermally operated (55-80 degrees C). With helium carrier gas and nitrogen diluent, a 10 mu l sample volume containing ammonia and nitrogen dioxide injected at 40 lbf in(-2) (2.8 x 10(5) Pa) can be separated in less than 30 min.

Colorless and soluble polymers with intrinsic viscosities as high as 30.6 dL/g( methanesulfonic acid, 30 degrees C) were obtained. The ultraviolet-visible spectrum of a polymer film cast from methanesulfonic acid under reduced pressure displayed no absorptions in the visible range (400-900 mu m). The polymer was thermooxidatively stable up to 420 degrees C in air as determined by thermogravimetric analysis. Fibers spun from a lyotropic polyphosphoric acid solution exhibited a tensile strength of 300-450 Ksi, a modulus of 26 Msi, and a compressive strength of 53 Ksi. Wide-angle Xray scattering patterns of polymer fibers indicated a 3-dimensional crystal structure rather than a nematic liquid crystal structure. (C) 1994 John Wiley and Sons, Inc.

Under certain deposition conditions a high density of surface outgrowths is observed. These outgrowths have been determined to be primarily YBa2Cu3O7 grains oriented such that the c-axis of the unit cell is lying parallel to the film/substrate interface plane. The size and number density of these outgrowths do not vary significantly with deposition time, which suggests that they nucleate at the substrate surface at the same time as do the grains oriented with their c-axis perpendicular to the film/substrate interface plane.

Pulsed laser deposition (PLD) was utilized to grow thin films of this material because it allows good control over film chemistry and crystallinity. Films were grown at different substrate temperatures in vacuum and in partial pressures of oxygen. The chemistry and crystallinity of the films were evaluated using X-ray photoelectron spectroscopy, Raman spectroscopy, and glancing angle X-ray diffraction. Friction coefficients and wear lives were measured using a ball-on-flat tribometer at room temperature and 700 degrees C. Films deposited in vacuum, at room temperature and at 300 degrees C, were oxygen deficient. To adjust chemistry and crystallinity, films were grown in a partial pressure of oxygen (i.e. 6.7 x 10(-1) Pa). Stoichiometric, crystalline films of PbMoO4 were produced when films were grown at 300 degrees C in this environment. PbMoO4 films were lubricious (mu = 0.35) and long lived at 700 degrees C, but at room temperature had high friction and failed quickly. The properties of the films grown at the different conditions are discussed. C1 NASA,LEWIS RES CTR,CLEVELAND,OH 44135. RAMSPEC RES,DAYTON,OH 45431.

The hardware used consists of two computer-controlled magneto-optic spatial-light-modulator arrays in conjunction with a CCD detector array as the computational hardware. Algorithms for binary-processing tasks are presented. We used magneto-optic spatial light modulators for parallel processing in a way that exploits multivalued output. Also, in carrying this evaluation out, we developed a new and efficient multiplication algorithm. Multiplication is an important operation in many digital systems, and the design of fast multipliers is of great interest to computer scientists and engineers. The speed of this computing system is evaluated. C1 USAF, OCB, ROME LAB, GRIFFISS AFB, NY 13441 USA. RP WU, YD (reprint author), UNIV LOWELL, DEPT ELECT ENGN, LOWELL, MA 01854 USA.

As was the case for similar reactions involving hydrazine, charge transfer and dissociative charge transfer occur in each reaction. The total reaction cross section is on the order of 50-100 Angstrom(2), and the amount of CH3NHNH2+ fragmentation in each case depends upon both the exothermicity of the charge transfer and the availability of internal degrees of freedom in the incident primary ion. The product ion kinetic energies are primarily thermal or near-thermal in the laboratory frame, as is often found for reactions involving efficient exothermic charge transfer. Charge transfer cross sections are also reported for the CO+ + H2O and CO2+ + H2O systems for the 0.2 less than or equal to E(cm) less than or equal to 6 eV range.

Photoluminescence (PL) measurements over the temperature range 2 K less than or equal to T less than or equal to 300 K yield two emission peaks, one of lower intensity and one of higher intensity. The lower intensity peak is believed to be Be related, while the higher intensity peak is from residual impurities. The emission energies of both PL peaks increase linearly with respect to the logarithm of excitation intensity, indicating the peaks are (D,A) transitions. Measurement of E(g) was achieved using optical absorption spectroscopy over the range 14 K less than or equal to T less than or equal to 300 K. A least squares fit of the absorption data using the Varshni equation produces a closed form expression for E(g)(T) with coefficients alpha=13.5X10(-4) eV/K, and beta=135 K.

Since this is a disease that is associated with both a very high level of total IgE and a high incidence of allergic respiratory disease, it behooves the practicing allergist to become familiar with the diagnosis and treatment of atopic dermatitis. This following discussion will focus on the identification of major and minor clinical features of the disease and review the spectrum of immune dysregulation that is frequently seen with these patients. The primary focus of this review will be directed at the identification of treatment options available to allergists within the published practice guidelines of the American Academy of Dermatology and practice guidelines that are currently being developed by the American Academy of Allergy & Immunology. Atopic dermatitis is an ''itch which rashes and not a rash which itches'' and therefore, any patient treatment program should address the multiplicity of potential trigger factors that provoke this itching. These factors include heat, humidity, and perspiration, in addition to the ingestion of certain food allergens and the topical exposure to both dust mite antigen and animal dander. Recent studies suggest that the pathogenesis of allergic disease entails a complex inflammatory process in which the TH2 lymphocyte might play a major role in shifting the immune response in favor of disease. Accordingly, recent immunomodulating treatments, such as interferon gamma and cyclosporine, might offer therapeutic options to the physician beyond the standard topical forms of treatment. In summary, the treatment of atopic dermatitis involves considerable clinical acumen, and the art of medicine plays a larger role in the treatment of this disease than in many other areas of medicine.

The apparent rareness may be because of a lack of recognition of the syndrome or its predisposing factors. Fluoxetine (Prozac, Dista Products Co, Division of Eli Lilly Co, Indianapolis, IN), sertraline (Zoloft, Roerig Division, Pfizer Inc, New York, NY), and paroxetine (Paxil, SmithKline Beecham Pharmaceuticals, Philadelphia, PA) belong to a new class of antidepressant medication: the serotonin reuptake-inhibitors (SRIs). The relative safety profile of the SRIs has led to their widespread use. However, a syndrome of excessive serotonergic activity, the ''serotonin syndrome'' (SS), has recently been recognized. It is characterized by changes in mental status, hypertension, restlessness, myoclonus, hyperreflexia, diaphoresis, shivering, and tremor. A high index of suspicion is required to make the diagnosis in these acutely ill patients. The most common agents implicated in SS are the monoamine oxidase inhibitors in combination with L-tryptophan or fluoxetine. A case of a patient with significant peripheral vascular disease who developed SS while taking paroxetine and an over-the-counter cold medicine is reported. There have been no prior reports of this interaction. Discontinuation of the offending agents, sedation, and supportive care are the mainstays of treatment. The interactions of serotonin with platelets and vascular endothelium are also discussed. C1 WILFORD HALL USAF MED CTR,DEPT PSYCHIAT,2200 BERGQUIST DR,ST 1,LACKLAND AFB,TX 78236.

This case is that of a patient with a perforated duodenal ulcer and previously undiagnosed NDI who received standard preoperative and postoperative hydration with normal saline, causing hypernatremia and an inappropriate diuresis. The resulting hypernatremia and hyperosmolality required aggressive hypotonic fluid replacement to return to preoperative values. Though refractory to 1-desamino-8-D-argenine-vasopressin (dDAVP), thiazide diuretics and nonsteroidal anti-inflammatory agents have a role in managing selected patients. Early diagnosis with careful fluid and electrolyte management are critical in successful management of these patients in the perioperative period. C1 USAF,MED CTR,DEPT GEN SURG,KEESLER AFB,MS 39534.

We show that distributed parameter systems described by certain parabolic partial differential equations often have a special structure that smooths solutions of the corresponding Riccati equation. This analysis is motivated by the need to find specific representations for Riccati operators that can be used in the development of computational schemes for problems where the input and output operators are not Hilbert-Schmidt, This situation occurs in many boundary control problems and in certain distributed control problems associated with optimal sensor/actuator placement.

To measure, and seek clinical correlates with, levels of substance P (SP) in the cerebrospinal fluid (CSF) of fibromyalgia syndrome (FMS) patients. Methods. CSF from 32 FMS patients and 30 normal control subjects was tested for SP by radioimmunoassay. Clinical measures included tender point examination and standardized questionnaires. Results. CSF SP levels were 3-fold higher in FMS patients than in normal controls (P < 0.001), but they correlated only weakly with tenderness found on examination. Conclusion. SP is significantly elevated in FMS CSF, but other abnormalities must exist in FMS to more fully explain the symptoms. C1 PFIZER INC,CENT RES,GROTON,CT 06340. ARMSTRONG LAB,BROOKS AFB,TX.

An anonymous survey was mailed to 396 TAC aircrew members in February 1992 to assess their experiences using extended weer soft contact lenses (EWSCL). Analysis was performed on those responses to compare differences between aviators who currently wear (CW), those who discontinued wear (DCW), and flyers who wore EWSCL while deployed to S.W. Asia for Desert Shield/Desert Storm. Of the 396 surveyed, 284 (72%) returned the survey and demonstrated that the daily use of EWSCL to be logistically practical and physiologically safe. No ocular malady was reported that would preclude continued use by aircrews. Desert Shield/Storm experiences documented that the use of EWSCL by USAF aircrews in a desert environment was possible. Logistical difficulties for the small number who either deployed with inadequate supplies or required replacement lenses were shown to be the primary challenge to the wear of EWSCL during Desert Shield/Storm. Subjectively, aircrews expressed strong beliefs that EWSCL contributed to their abilities as combat aviators. C1 USAF,SCH AEROSP MED,BROOKS AFB,TX 78235.

This article reviews the literature to determine if such concerns are valid. After 25 years of clinical experience with ketamine, fewer than 10 cases document the occurrence of delayed psychological effects potentially attributable to that drug. In most cases, the delayed effects were temporary, resolving within 3 weeks. Further, there were no long-term psychological effects clearly attributable to ketamine. Children who manifested delayed effects had several other factors present placing them at risk for long-term psychological changes independent of their receiving ketamine. Several controlled studies investigating the risk of long-term psychological effects due to ketamine fail to document that the risk of permanent psychological changes from ketamine is any greater than that from any other anesthetic. In conclusion, there is no evidence in the literature that ketamine presents a higher risk compared to other anesthetics for causing long-term psychological effects that result in a patient not being able to return to his or her occupation. The decision of whether to use ketamine should be a clinical decision weighing relative risks versus benefits, and not a decision based on the patient's career.

Nonetheless, the theory put forth by Geschwind and colleagues retains an important legacy despite a multitude of faulty assumptions and predictive failures. Also offered is a brief synopsis of a new model that explains the many positive relationships found among various neurodevelopmental disorders and medical conditions, as well as why abnormal handedness distributions occur in some but not other neurodevelopmental disorders.

An alternative is to use an artificial intelligence system called a neural network (NN) which simulates biological intelligence. To evaluate the potential applicability of the latter method, we compared the ability of LR and NN techniques to predict cardiac events after noncardiac surgery. A total of 200 patients (training group) underwent cardiac risk assessment before major noncardiac surgery using 17 clinical parameters and 7 quantitative indices based on dipyridamole-thallium imaging. There were 21 postoperative myocardial infarctions and/or cardiac deaths. Data from the training group were used to develop two predictive from the training group were used to develop two predictive models: one based on backward stepwise LR multivariate statistical analysis and the other one using a neural network. Both models were then validated on a second group of 160 consecutive patients also referred for preoperative risk stratification (validation group). The NN consisted of 14 input, 29 hidden, and 1 output neurons and used a back-propagation algorithm (learning rate 0.2, training tolerance 0.5, sigmoid transfer function). The sensitivity, specificity, positive and negative predictive accuracies for the prediction of postoperative events in the validation group of 160 patients were, respectively, 67% (6/9), 82% (124/151), 18% (6/33), and 98% (124/127) for LR, and 67% (6/9), 96% (145/151), 50% (6/12), and 98% (145/148) for the NN, with a difference in specificity which attained statistical significance (p<0.01). Artificial intelligence may provide a useful alternative to conventional LR statistical analysis for the purpose of preoperative cardiac risk assessment.

Many different etiologies for pericarditis have been described. In some instances, such infections have caused severe hemodynamic complications and life-threatening conditions. Mycobacterium kansasii is known to cause pulmonary and disseminated infections in immunocompromised patients, including those with AIDS; however, to the best of our knowledge, pericarditis due to an infection with this organism has not been described. We report the first three cases of M. kansasii pericarditis in patients with AIDS. C1 WILFORD HALL USAF MED CTR,DIV INFECT DIS,SAN ANTONIO,TX.

This study compared learning from Stat Lady vs learning from a paper-and-pencil Workbook version of the identical curriculum, and addressed the question: ''What does the computer contribute to learning?'' Findings showed that Stat Lady learners performed at least as well (and in some cases, much better) on the outcome tests compared to the Workbook group. Specifically, we found that (a) Stat Lady was clearly the superior environment for high-aptitude subjects, (b) Stat Lady subjects acquired significantly more declarative knowledge than the Workbook subjects, and (c) regardless of aptitude, the majority of learners found the Stat Lady condition to be significantly more enjoyable and helpful than the Workbook condition. Implications for the design of instructional systems and further research are offered. C1 GALAXY SCI CORP, LACKLAND AFB, TX 78236 USA.

METHODS: A retrospective review of records of the prospective database revealed 35 patients who had been diagnosed with anal canal carcinoma and treated with chemoradiotherapy at Wilford Hall USAF Medical Center (tertiary referral hospital) from 1981 to 1991. RESULTS: Patients ranged in age from 35 to 80 (mean, 59) years, and 63 percent were women. Primary tumors ranged from 1 to 8 cm in diameter (mean, 3 cm). The first six patients had an abdominoperineal resection (APR) after chemoradiotherapy, and no residual tumor was identified in the specimens. In the subsequent 29 patients who did not have APR, 5 had moderate problems with anal continence, and one required a diverting colostomy for incontinence. Follow-up ranged from 4 months to 12.9 years (mean, 5.2 years). There were two pelvic recurrences, and three patients developed distal metastasis. Eight patients died during followup, including three with recurrent or persistent disease. Five-year survival using life-table analysis was 89 percent. CONCLUSION: Long-term follow-up confirms that chemoradiation remains the preferred therapy for epidermoid carcinoma of the anal canal.

The serum estradiol (E(2)) level was elevated, the testosterone (T) level was normal, and the gonadotropin levels were high-normal. The patient underwent unilateral mastectomy for cosmetic purposes. Problems with mood and libido plus the development of gynecomastia in the contralateral breast caused him to seek further treatment. Testolactone (TL) at 400 mg/day afforded complete resolution of his symp toms and gynecomastia, both of which recurred when the drug was withdrawn and responded to resumption of therapy, The serum E(2) level initially fell during TL therapy but returned to pretreatment levels after 1 month. The serum T, however, doubled during treatment periods, increasing the androgen/estrogen ratio. Testolactone appears to effectively treat this condition by raising the androgen/estrogen ratio without lowering absolute E(2) levels.

The distribution of Tru-Trax results in couples with normal semen analyses and Insler scores showed significantly greater penetration in bovine (22.3 +/- 6.0 mm) than in human mucus (20.3 +/- 5.4 mm) (P < 0.001). However, the lower limit of the 95% confidence interval of the normal population with either type of mucus was similar to 10 mm. This limit was significantly lower than that described by the kit manufacturer. The predictive value for post-coital tests using human mucus in the Tru-Trax system was good (>90%) in all groups. The overall penetration into either human or bovine mucus was significantly correlated with the percentage of motile spermatozoa in the semen sample (P < 0.001). In conclusion, in-vitro cervical mucus penetration tests with the Tru-Trax system are related to in-vivo post-coital tests, although the lower limit of the range of anticipated results in the normal population was significantly lower than that described by the manufacturer. The ultimate value of this type of testing will await clinical trials which evaluate clinical end-points such as pregnancy rates. C1 NICHHD,DEV ENDOCRINOL BRANCH,BETHESDA,MD 20892.

The numerical dispersion of a time-harmonic plane wave propagating through an infinite, two-dimensional, vector finite element mesh composed of uniform quadrilateral elements is investigated in this work. The effects on the numerical dispersion of the propagation direction of the wave, the order of the polynomials used for the basis functions, and the electrical size of the elements are investigated. Simple formulas are presented which are excellent approximations to the exact numerical dispersion. The numerical dispersion is validated by a numerical example.

IT tasks were length, numeracy, and letter-string classifications made difficult by backward masking. IT tasks used accuracy as a performance measure. VS tasks were searches of figural, numeric, or word targets in arrays of similar items. VS tasks used reaction time under a high accuracy set as a performance measure. In both experiments IT correlated significantly to both IQ and VS, and in both experiments the negative correlation of IT to VS was significant controlling for IQ. The results provide evidence that IT performance has a component related to IQ tests and an independent component related to other processing speed tests such as visual search.

After determining the length of record to attain stability for the former, and the dates (of the year) on which temperatures are a maximum and minimum, these parameters are mapped for North America. For MITV there is a general association with continentality and the location of the surface polar front zone; the lag patterns bear only a slight resemblance to continentality.

Our comparison of these data with GOES-7 imagery revealed that lightning data can help define the development, linearity, and maximum intensity of a frontal band as seen with the correlation of currents discharged by lightning to ground with associated IR temperature fields. Lightning data also revealed a dramatic increase in convection equatorward of Hurricane Chantal's vortex upon her rapid intensification and landfall, and the heavy rainfall amounts associated with the tropical storm correlated to areas of rather frequent lightning activity west of Galveston, Texas, on 1 August 1989.

The model includes elementary surface processes such as adsorption, evaporation, and migration of atoms. The model is applied to the study of the surface segregation phenomenon during In doping of Si. The doping studies were performed for the following growth conditions: T in the range 500-750 degrees C; a growth rate of 1 mu m/h; and a flux ratio J(In)/J(Si) equal to 2.0x10(-4). The predicted sticking coefficient of In versus 1/T shows excellent agreement with experiments. The sticking coefficient decreases with T due to surface segregation aided evaporation of In at higher temperature. The predicted dopant depth profile also shows excellent qualitative agreement with experiments. The surface segregation of In occurs due to a strong repulsive interaction between In and the host lattice. The results of this study show that there is a dopant-depleted zone (DDZ) where the In concentration is lower than both the bulk and the top surface layer The observed DDZ qualitatively matches that observed in experiments. The time and growth rate dependencies of the phenomenon are studied and found to be in good agreement with experiments. The model was used to study delta doping of dopants in the range of 673 to 973 K. The results are in qualitative agreement with experimental results. With an increase in temperature, the dopant profiles become sharper. This is caused by a smoother growing surface at higher temperatures.

Group 1 was a control, whereas group 2 had the dental pulp of the first mandibular molar acutely exposed, and group 3 had dental pulp exposure for 10 days. All animals were injected with I-125-labeled dexamethasone phosphate into the right mandibular vestibule. Each group of 12 was divided into subgroups of 4 and sacrificed at 1, 2, or 4 h. The soft tissue on the buccal side and the mandible with the molars were collected and the radioactivity determined. Dexamethasone was absorbed from the injection site and distributed to the ipsilateral mandible and to the contralateral muscle and bone similarly, regardless of the treatment. Results also indicate a possible osseous affinity for this steroid, which could be beneficial in relieving the pain of intraosseous endodontic flare-ups.

Ge-doped silica is simulated as a cluster that consists of a GeO4 unit together with its four nearest SiO4 units. Electron trapping does distort the local symmetry of the Ge center where the GeO4 unit is not exactly tetrahedral. The calculations of the microscopic NLO properties in terms of static hyperpolarizabilities show a large, noticeable increase in beta related to second-harmonic generation or Kerr effect for the Ge(1) center upon electron trapping.

This system requires only one laser that is double-pulsed to produce droplet-displacement images. Direct image digitization and processing using a combination of a charge-coupled device camera, controller, microcomputer, and custom software has shortened the image-processing time from days to minutes. Important features of this effective image-analysis process include 1) a highspeed, general-purpose scheme capable of analyzing image size and shape factor, therefore determining droplet location; 2) a rapid method of computing two-dimensional spatial correlation; 3) a compact data structure for merging image-intensity and geometry information to reduce data storage and improve tracking accuracy; and 4) a newly developed three-point interpolation scheme that preserves the two-dimensional vector field for postprocessing. Application of this imaging system to the study of liquid jets transversely injected into a crossflow has yielded a much improved formulation that takes into account multizone jet behavior in describing jet penetration into the crossflow. The measurement of droplet and spray fragment velocities throughout the spray field indicated substantial droplet-freestream velocity slip even at far-downstream locations.

We describe a method for synthesizing and optimizing a multiple-bandwidth adaptive-optics control system from performance estimates previously derived for single-bandwidth control systems operating over a range of bandwidths. The approach is applicable to adaptive-optics systems that use either one or several wave-front sensing beacons and also to systems that include multiple deformable mirrors for atmospheric-turbulence compensation across an extended field of view. Numerical results are presented for the case of an atmospheric-turbulence profile consisting of a single translating phase screen with Kolmogorov statistics, a Shack-Hartmann wave-front sensor with from 8 to 16 subapertures across the aperture of the telescope, and a continuous-face-sheet deformable mirror with actuators conjugate to the corners of the wave-front-sensor subapertures. The use of multiple control bandwidths significantly relaxes the wave-front-sensor noise level that is permitted for the adaptive-optics system to operate near the performance limit imposed by fitting error. Nearly all of this reduction is already achieved through the use of a control system that uses only two distinct bandwidths, one of which is the zero bandwidth.

The MIL-H-53119 formulation includes an anticorrosion additive and a fluorinated sulfonamide antiwear additive. The sulfonamide additive reduced the friction and wear between alloy steel specimens during rubbing. The wear-reducing mechanisms of this additive in CTFE were studied using a reciprocating tribometer and various surface analysis techniques. The additive increased the iron chloride-to-oxide concentration ratio within the surface film. Since the additive is chlorine-free, it must have increased the surface interactions between the CTFE fluid and the steel substrate to form chloride-rich films.

A 124-element photodiode detector array provided high-speed monitoring (0.5 ms/frame) of evoked neural activity in the SCN, while a larger 464-element photodiode array yielded improved spatial imaging with some loss in temporal resolution (1.6 ms/frame). Brief electrical stimulation of the optic nerves evoked a propagated compound action potential that was recorded optically as a single transient deplorization in many slice regions, including the SCN. Only within the SCN, however, was this optic tract signal followed by additional voltage-dependent optical responses which exhibited a fast and a slow depolarizing component. The initial upstroke of the fast component was Ca2+-insensitive and is presumed to reflect activity in presynaptic RHT afferents. The remainder of the fast depolarization and the slow depolarization were Ca2+-sensitive. These responses were labeled the early population excitatory postsynaptic potential (Early P.E.P.S.P.) and the Late P.E.P.S.P. respectively. The Late P.E.P.S.P. was not enhanced by K+ channel blockade, suggesting that glial depolarization is not the primary source of this component. Drugs known to suppress RHT-evoked SCN field potentials also suppressed the Early and Late P.E.P.S.P.'s recorded optically in the SCN. Unexpectedly, the Early P.E.P.S.P. was also reduced by the GABA(A) antagonist, bicuculline. Surface plots of normalized peak amplitudes showed that both SCN components had similar spatial distributions within the SCN, although the Early P.E.P.S.P. tended to be slightly more prominent within the medial SCN in some preparations. It is suggested that the Early P.E.P.S.P. represents firing of monosynaptically activated SCN neurons, while the Late P.E.P.S.P. reflects polysynaptic activity within the intrinsic SCN neuronal network that may be involved in the light entrainment of the circadian oscillator.

Methods: Twenty gravidas at 24-32 weeks' gestation were treated for preterm labor with 50 mg indomethacin orally, followed by 25 mg every 6 hours for 3 days. Bleeding time, prothrombin time (PT), and activated partial thromboplastin time (aPTT) were measured before and 48 hours after initiation of therapy. Statistical analysis was performed by paired t test and Fisher exact test. Results: The typical participant was 22 years old, nulliparous, and 26.2 weeks' gestational age at enrollment. The mean bleeding time was 4.5 minutes before therapy and 8.8 minutes after therapy (P < .0001, mean difference 4.3 minutes, 95% confidence interval 2.9-5.8). Nineteen of the 20 subjects experienced an increase in bleeding time and 13 had abnormal bleeding times. No clinically significant changes in PT or aPTT were noted. The mean period from treatment to delivery was 60.2 days. No cases of neonatal intraventricular hemorrhage or maternal postpartum hemorrhage were noted. Conclusion: Oral indomethacin treatment for tocolysis has no impact on PT and aPTT; however, profound acute changes in maternal bleeding time occur.

Eighty extracted human third molar teeth were randomly separated into four groups of 10 for each of the dentin bonding systems tested (All-Bond 2, Scotchbond Multi-Purpose). Group A specimens were not contaminated; primer/adhesive/resin were applied according to manufacturers' instructions. In Group B, samples were contaminated for 15 seconds with fresh whole human saliva, and then forcibly dried with a blast of oil-free air; this occurred after application of the primer but prior to application of adhesive. In Group C, contamination occurred after application of adhesive, prior to application of resin. In Group D, saliva was allowed to contaminate the surface as the primer was being applied, without forcible removal. Specimens were then thermocycled, mounted, and tested in shear on an Instron at 7 days. Bond strengths in MPa were obtained, and data were analyzed using a one-way ANOVA, at the P = 0.05 level of significance. Although shear bond strengths were lowered in saliva-contaminated samples, there was no statistically significant difference between group means.

For the control group, 10 aluminum dies (25 mm x 12 mm x 10 mm) were milled with 3.0 mm x 3.0 mm slots, which were filled with hand-condensed Tytin amalgam with no underlying base. For experimental groups, 10 aluminum dies of equal dimension were milled with 3.5 mm x 3.0 mm slots. Following manufacturer's instructions, the nine base materials were successively placed in these 10 dies using a depth-limiting device made of light-transmitting clear acrylic to ensure a 0.5 mm thickness, and Tytin amalgam was again condensed over each base such that the depth of the amalgam equalled that in the control. All test specimens were stored in 100% humidity for 48 hours then fractured in compression on an Instron machine. Mean force, in Newtons (S D in parentheses), required to fracture the specimens was: Control: 1934(210), Zinc Cement: 1874(147), GlasIonomer Base Cement: 1839(174), Ketac-Bond: 1723(225), Vitrebond: 1485(155), Photac-Bond: 1422(294), Advanced Formula II Dycal: 1296(237), VLC Dycal: 1035(116), Variglass: 909(294) and Timeline: 906(275). ANOVA and Student-Newman-Keuls statistical analysis (alpha = 0.05) indicated that the autocuring glass ionomers, GlasIonomer Base Cement and Ketac-Bond, and a zinc phosphate cement, Zinc Cement, provided significantly more fracture resistance for amalgam than the other bases tested and were not statistically different from a no-base control.

Techniques exist for recovering near diffraction-limited performance of an imaging system in the presence of atmospheric turbulence. These image enhancement techniques include speckle imaging, deconvolution, and adaptive optics. A turbulence chamber has been designed and built for laboratory testing of current and future adaptive optics and image enhancement techniques. The turbulence is produced within a chamber consisting of two small fans and a heating element. The effects of the generated turbulence on optical propagation are directly measured by sensing the perturbed wavefront phase. The wavefront phases are measured using a shearing interferometer. The statistical properties of the turbulence are then characterized by means of estimating the phase structure function from the wavefront phase measurements. We found that the estimate of the phase structure function depends only on the magnitude of the separation between two points on the optical wavefront and follows the Kolmogorov 5/3 power law.

In rhesus monkeys, three repeated acute low-dose (2.1 to 2.8 mu g/kg) soman exposures, separated by intervals > 5 weeks, did not change baseline compensatory tracking performance or the soman ED(50). Atropine therapy (97 mu g/kg) alone had no effect on soman ED(50). Addition of pyridostigmine pretreatment (150 mu g/kg and 2-PAM therapy (17 mg/kg) to atropine therapy increased the soman ED(50) for a performance decrement from 2.27 mu g/kg to 2.58 mu g/kg, an insignificant protective effect. At the soman ED(50) for behavioral decrements, pyridostigmine pretreatment increased the inhibition of serum ChE observed immediately after soman exposure, but reduced the extent of permanent inhibition. The 2-PAM therapy reduced serum ChE inhibition from about 80% to less than 70%. These effects on the time course of ChE inhibition following soman exposure appear to combine additively. These chemical countermeasures do not prevent soman-induced performance decrements, even though they are effective in protecting lives after much higher doses. The soman doses used produce only small, transient performance decrements; animals so exposed can, thus, be used repeatedly in such studies.

The electron density distribution is reconstructed for the region bounded by the satellite orbit and the line of ground receivers. A new reconstruction algorithm is described which satisfies the TEC records, makes use of an ionospheric model, and allows the incorporation of complementary measurements. The new algorithm also accepts relative (rather than absolute) TEC as input data. A comparison of the new algorithm and one used recently shows significant improvement over early techniques, particularly when a scaled ionogram is included in the data.

Segments of Dacron and Gore-Tex graft were placed in the following solutions: saline (S), 6% and 9% P, and 25%, 50%, 75%, and 100% A, and stored at 23-degrees +/- 1-degree-C for 72 hours. Axial maximum load (in kilonewtons, KN) and strain (in mm/mm) were determined with an Instron universal testing machine (Instron Corporation, Camden, MA). Samples from the S, 9% P, and the 100% A groups were evaluated using a scanning electron microscope. Results. Dacron tensile strength decreased a maximum of 23% after exposure to 50%, 75%, and 100% A. Dacron strain capacity decreased after exposure to A (50%, 75%, 100%) and P (6%, 9%). Scanning electron microscope of both P and A showed significant degradation. No changes were found in the Gore-Tex group after exposure to P or A, however, scanning electron microscope of the 100% A sample showed moderate fiber degradation. Conclusions. The study shows that Dacron woven grafts are degraded by concentrations of A of at least 50%, and to a lesser extent, concentrations of at least 6%, while Gore-Tex had only minimal changes. While neurolytic block offers distinct advantages in patients with terminal cancer pain, the findings suggest that the use of more conservative modalities, such as oral medication regimens, be considered for the treatment of intractable pain in patients with vascular prosthetic grafts that are proximate to the proposed site of neurolysis.

Under uniaxial tension, the angle-plied composite specimens were subjected to a considerably large interply shear strain before failure. The composite specimens exhibited infinite fatigue life when stress amplitude was below a threshold level, i.e., fatigue endurance limit. Under cyclic stresses exceeding the endurance limit, localized damage in the form of fiber-matrix debonding and matrix cracking was formed and developed into the delamination eventually leading to gross failure of the composite. The process of damage accumulation was accompanied by a continuous increase of cyclic strain as well as temperature. Fatigue lifetime and the resistance to damage accumulation of aircraft tire carcass composite were strongly influenced by cyclic frequency. The use of higher frequency resulted in shorter fatigue lifetimes at a given stress amplitude and lower endurance limit. The extent of dynamic creep at gross failure, which is defined as the increase of cyclic strain beyond initial elastic deformation, was roughly independent of stress amplitude under the frequency of 1 Hz, but decreased with higher stress amplitude when the frequency was raised to 10 Hz. Obviously a critical level of dynamic creep exists for gross failure of the composite and this level appears to be independent of the stress amplitude at low frequency. When the frequency is sufficiently high, heat generation due to hysteretic loss is expected to degrade the materials. In this situation, the critical level of dynamic creep for gross failure seems to be reduced by the loss of matrix flexibility as well as fiber-matrix bonding strength, with the degree of reduction becoming greater under higher stress amplitude.

The samples studied were coupled InxGa1-xAs-GaAs quantum wells. In all cases the excitons associated with antisymmetric wave functions were found to have larger diamagnetic shifts than the excitons associated with symmetric wave functions. This suggests that the excitons associated with antisymmetric wave functions have a smaller binding energy than excitons associated with symmetric wave functions. These properties are consistent with the fact that excitons associated with antisymmetric wave functions are less confined than excitons associated with the symmetric wave functions.

In order to prevent spillovers from the modal couplings of feedback forces, the distributed actuators are spatially shaped to be orthogonal to those undesirable modes. Consequently, the distributed: feedback functions evolve to modal feedback functions which can be represented as a gain factor and a spatially distributed mode shape (actuator) function. In practice, the actuator can be shaped and convolved based on the prescribed mode shape function and the gain factor can be treated as a weighting factor. To demonstrate the utilities of the generic theory, distributed orthogonal convolving modal:actuators designed for a circular ring shell are proposed and their control effectiveness evaluated. Analyses suggested that the primary control action comes from the in-plane membrane control forces; the contribution from the electric bending moment is relatively insignificant for lower natural modes, i.e., n < 10. It was observed that the control effect increases as the structural stiffness decreases or the structural flexibility increases. Increasing the control moment arm (as the ring becomes thicker) of the actuator layer seems insignificant in the overall control effect for lower natural modes. C1 AC COMPRESSOR,APPLETON,WI 54915.

The absorption for lambda greater than or similar to 1.0 mu m (below band edge) varies directly with n via free-carrier interconduction-band transitions, while the absorption for lambda less than or similar to 0.95 mu m (near band edge) varies inversely with n because of band-filling effects. Both phenomena are highly useful for n(+)-GaAs wafer characterization. (C) 1994 American Institute of Physics. C1 USAF,WRIGHT LAB,ELRA,SOLID STATE ELECTR DIRECTORATE,WRIGHT PATTERSON AFB,OH 45433.

Sexual behavior in the context of the doctor-patient relationship has potentially devastating effects on health care and the psychological well-being of patients. Method. To investigate the exposure of medical students to patient-initiated sexual behaviors (defined as any kind of sexual remarks or behaviors directed toward students by patients), 253 third- and fourth-year students and 1992 graduates of Wright State University School of Medicine were surveyed in the summer of 1992. The instrument used was a 16-item self-administered questionnaire, which solicited data on each respondent's age and gender as well as responses to patient-initiated sexual behavior, various aspects of the clinical settings in which such behavior occurred, and the effects of this behavior on the respondent's education and future practice. Results. Of the 253 students and graduates surveyed, 155 (61%) responded (73 women and 82 men.) Fifty-two (71%) of the women and 24 (29%) of the men reported at least one instance of inappropriate sexual behavior by a patient. Frequently students had encountered inappropriate behavior more than once. Conclusion. Even assuming that all the nonrespondents had not experienced inappropriate sexual behavior, the proportion of students and graduates who did report such behavior is considerable. Understanding the extent and nature of patient-initiated sexual behavior experienced by physician trainees is hampered by differing definitions of inappropriate sexual behavior, subjective reporting, and variable perceptions of situations dependent on previous experience. Since patient-initiated sexual behavior can cause physicians to distance themselves from their patients and can put patients at risk for sexual exploitation, training in medical school is necessary to help students effectively manage such complex behavior.

Structural mass and a quadratic performance index constitute the vector objective function. The closed-loop performance index is taken as the time integral of the Hamiltonian. Constraints on natural frequencies, closed-loop damping, and actuator forces are also considered. Derivatives of the objective and constraint functions with respect to structural and control design variables are derived for a finite element beam model of the structure and constant feedback gains determined by independent modal space control. Pareto optimal designs generated for a simple beam demonstrate the benefit of solving the integrated structural and control optimization problem.

An acidification procedure has resulted in 40-70 percent p24 antigen positivity across HIV clinical stages, although the predictive value of post-acidification p24 antigen for disease progression has not been fully validated. We hypothesized that there would be significant differences in p24 antigen positivity between matched cohorts of rapid progressors (RP) and slow progressors (SP). Seven hundred sixteen people enrolled in the USAF HIV Natural History Study were stratified according to the slope of CD4 change over time. RP were defined as people in the fastest 15 percent of CD4 decline who also progressed at least 2 Walter Reed (WR) stages. SP were defined as people in the slowest 15 percent of CD4 decline who did not progress more than 1 WR stage. Twenty-five RP were matched to 25 SP based on initial CD4 count (median CD4 RP = 750, SP=720), WR stage, age, and duration of follow-up (RP=1086 days, SP=1126 days) with no significant differences between groups. Ten/25 (40 percent) of the RP and 2/25 (8 percent) of the SP were p24 antigen positive by the acidification assay (p=0.018). Using the standard assay, 6/25 (24 percent) of RP and 1/25 (4 percent) of SP were p24 antigen positive (p=0.098). There were no quantitative differences between p24 antigen positive RP and SP. p24 antigen as detected with the acidification assay was predictive for HIV rapid progressors when compared to slow progressors in early stage HIV patients even when controlling for initial CD4 count, age, and duration of follow-up.

An inner-outer loop modular control structure is used to provide good flying quantities in the presence of highly structured uncertainty across a wide flight envelope. Simple, low-order control laws are designed for a version of an F-18 aircraft model augmented with thrust vectoring nozzles. A minimal-order H-infinity design algorithm is used to aid in the design of an inner loop equalization controller. Structured singular value synthesis is used to design outer loop implicit model-following controllers. Different control laws are found for high and low dynamic pressure conditions, and controller commands are blended for a small region of dynamic pressure. Daisy-chaining is used to blend elevator and thrust vectoring commands. Structured singular values are used to analyze stability robustness to structured parametric uncertainty, actuator and sensor unmodeled dynamics, and structured uncertainty corresponding to controller blending. A nonlinear simulation is used to show that the aircraft performs well across the Right envelope during outer loop controller blending and thrust vectoring actuation.

Between October 1986 and March 1990, 37 patients with relapsed or refractory lymphoma received escalating doses of combination chemotherapy followed by autologous bone marrow transplant (ABMT). Twenty patients with Hodgkin's disease (HD) and 17 patients with intermediate or high grade non-Hodgkin's lymphoma (NHL) initially received conventional-dose therapy with either a 7 week course of modified MACOP-B or a single dose of cyclophosphamide (CY) at 2 g/m(2) depending on prior therapy and response. Regardless of response, patients then received escalating doses of BACE, toxicity permitting. Ten patients obtained complete responses (CR) and 12 patients were partial responders (PR), CR + PR (75%) with modified MACOP-B and 7 (64%) patients obtained PR with CY. The maximum-tolerated dose (MTD) for BACE was determined to be carmustine 700 mg/m(2), Ara C 1500 mg/m(2), CY 150 mg/kg and etoposide 1500 mg/m(2). When Ara C was escalated from 1500 mg/m(2) to 3000 mg/m(2) holding the other drugs at the prior doses, the next two patients died secondary to diffuse alveolar damage. Overall and event-free survivals are identical with 14 of 37 patients (38%) alive with a median follow-up of 61 months (range 38-79 months). Ten patients were treated at the MTD, none of whom died a toxic death and 3 (30%) are alive with a median follow-up of 42 months (range 38-52 months). We defined the MTD of BACE showing pulmonary toxicity to be the dose-limiting non-hematologic toxicity. It will require further study to determine if the MTD described here best balances efficacy and toxicity.

It has a novel mechanism of action whereby it may decrease excitation by inhibiting glycine binding at the NMDA receptor, and it appears to have neuroprotective properties in addition to antiepileptic ones. A number of animal models have demonstrated felbamate to have a broad range of efficacy as well as a favorable safety profile. In humans it has been potentially linked to some cases of aplastic anemia. It is effective in the treatment of partial and secondarily generalized tonic-clonic seizures as well as seizures associated with the Lennox-Gastaut syndrome, especially drop attacks. It may also be effective against atypical absence as well as other seizure types. Ferbamate monotherapy is generally well tolerated, with such side effects as insomnia and anorexia occurring most commonly. Felbamate shows great promise as a useful antiepileptic drug, but its role in clinical practice awaits further investigation of recently reported cases of aplastic anemia.

From July 1989 to June 1990, we conducted aerial surveys in the oceanic north-central Gulf (long. 87.5 degrees W-90.5 degrees W) with the following objectives: 1) to determine which cetacean species were present; 2) to document temporal and spatial distribution for each species; and 3) to estimate relative abundance for each species. We surveyed a total of 20,593 transect km and sighted at least 18 species. Of 278 identified herds (6,084 animals), 94% of the herds and 98% of the animals represented seven species or species groups: Risso's dolphin, Grampus griseus (22% of the herds, 13% of the animals); sperm whale, Physeter macrocephalus (16%, 1%); bottlenose dolphin, Tursiops truncatus 14%, 7%); Atlantic spotted dolphin, stenella frontalis (13%, 15%); pygmy sperm whale, Kogia breviceps, and dwarf sperm whale, Kogia simus (12%, 1%); striped dolphin, Stenella coeruleoalba, spinner dolphin, S. longirostris, and clymene dolphin, S. clymene (9%, 34%); and pantropical spotted dolphin, S. attenuata (8%, 27%). Each of these species or species groups was sighted throughout the area surveyed in at least three seasons. Mean water depths of bottlenose dolphin and Atlantic spotted dolphin sightings were less than 400 m; mean water depths of Risso's dolphins and pygmy and dwarf sperm whales were between 400-600 m; and mean water depths of striped, spinner, and clymene dolphins, sperm whales, and pantropical spotted dolphins were greater than 700 m. Mean herd sizes varied by species and species groups and ranged from 1.9 animals for pygmy and dwarf sperm whales to 87.8 animals for striped, spinner, and clymene dolphins.

In this report we have employed recurrent limbic seizures as a means of studying the effects of this form of enhanced neuronal activity on cellular morphology and, in particular, on the incidence of somatic spines on the dentate gyrus granule cells. Seizure activity was induced by the placement of focal, unilateral electrolytic lesions in the dentate gyrus hilus of adult rats. At various intervals postlesion, rats with behaviorally verified seizures were sacrificed, and the hippocampi contralateral to the lesions were removed and prepared for electron microscopy. Quantitative analysis showed that as early as 5 hours postlesion there was a dramatic increase in the density and morphological complexity of spines on the perikarya of the granule cells in rats that received seizure-producing hilus lesions when compared to granule cells from control rats. Many of the somatic spines received asymmetric synapses. The increase in somatic spines was dependent on seizure activity and persisted for at least 1 month following a single recurrent seizure episode. CA1 pyramidal neurons, which exhibit changes in gene expression in response to hilus lesion-induced seizures but do not normally possess somatic spines, did not exhibit an activity-dependent elaboration of somatic spines. Thus, the seizure-induced elaboration of somatic spines represents an amplification of an existing feature of the granule cells and not an effect occurring throughout hippocampus. These data provide evidence for very rapid and long-lasting structural plasticity in response to brief episodes of seizure activity in the adult brain. (C) 1994 Wiley-Liss, Inc.

The laser performance is governed by gas phase kinetic processes, which redistribute the absorbed pump energy during the evolution of the laser pulse.

Peak output power of about 550 MW at 9.45 GHz was radiated in an 8-ns pulse. We describe experiments which study the relative efficiencies of microwave generation from a two-stage nonuniform amplitude slow wave structure and its variations without an initial stage. Experimental results are compared with 2.5 D particle-in-cell computer simulations. Our results suggest that prebunching the electron beam in the initial section of the nonuniform BWO results in increased microwave generation efficiency. Furthermore, simulations reveal that, in addition to the backward propagating surface harmonic of the TM(01) mode, backward and forward propagating volume harmonics with phase velocity twice that of the surface harmonic play an important role in high-power microwave generation and radiation.

Results show that, compared to a uniform interaction tube, a gyro-BWO with a 10% downtapered tube produces the following effects: 1) highest microwave peak-power (up to about 100 MW in internal tube), a factor of 2 higher than the uniform tube, 2) more reproducible long-pulse (400-500 ns) emission, and 3) the largest inferred-integrated energy (factor of 2.5-3 increase). Experiments show high power microwave spikes with lower power plateaus. Experimental observations are in qualitative agreement with MAGIC code simulations of uniform and tapered-tube gyro-BWO's.

The results, shown for a network trained and tested over a recorded head position time series, imply that the technique is a viable method for reducing latency in the head-slaved computer generated imagery of a flight simulator. The procedure for building the network-based estimator is straightforward, using example-based learning to associate certain transformations on the current position to the value of position at a later time. The success of the approach is found to be dependent on the degree to which the training data represent the full range of motion found in the simulator. A single-output network is shown to accurately estimate rotational position (azimuth) over all motion types of interest, a range from low through high acceleration motion. It is also shown that performance can be improved by adding data variations to the network training set. The network's accuracy is evaluated for several different prediction intervals, from 150 msec through 350 msec, with the best results found to be at 200 msec and below. Finally, the results for a single-output network are extended to a two-output network, demonstrating prediction of both elements of the look-angle (azimuth, elevation) in one RBF network.

T cells from rhesus monkeys (Macaca mulatta) are less responsive than human cells, producing few metaphases when thousands are required, e.g. in biological dosimetry studies. We show that staphylococcal enterotoxin A (SEA), one of the most potent mitogens known, at a concentration of 0.5 mu g/ml stimulated peripheral lymphocytes to grow with a mitotic index (MI) averaging 0.13 metaphases/cell in old, irradiated rhesus macaques. This was significantly greater (p < 0.001) than that produced by PHA (MI < 0.01) in lymphocytes from the same animals. Whole blood was cultured for 96, 120 and 144 h for five irradiated individuals and for two controls. All cells cultured with SEA produced a high MI with a peak response at 120 h whereas the same cultures showed low MI for each PHA stimulated culture.

Several options for removing bromate after its formation are evaluated: reduction with ferrous iron (Fe2+), reduction on the surface of activated carbon, ultraviolet irradiation, and high-energy electron beam irradiation. For all the processes, bromide was found in the treated water, which indicates that the dominating mechanism of bromate removal is chemical reduction. If Fe2+ is introduced after preozonation, it may function both as a reducing agent for bromate and as a coagulant for dissolved organic carbon removal.

To determine how practicing allergists deal with some of these dilemmas, a questionnaire was mailed to 3500 physician members and fellows of the American Academy of Allergy and Immunology. It was also sent to each of the allergy training program directors in the United States to determine what is currently taught to fellows in training. Benzylpenicilloyl-polylysine (Pre-Pen) and fresh penicillin G are used for skin testing by more than 86% of both respondent groups, whereas minor determinant mixtures are used by only 40%. Epicutaneous followed by intradermal injection was the skin test technique used by 86% of these allergists. More than 90% said they would skin test in cases of reaction history of urticaria, whereas only 1.5% would test in cases of family history of penicillin allergy. Practicing allergists and program directors differed slightly when queried about cephalosporin cross-reactivity. Program directors were more cautious in their use of cephalosporins with patients allergic to penicillin. Program directors were also more likely to repeat skirt testing before future penicillin courses than were practicing allergists. Clearly, some individual approaches to the diagnosis and management of beta-lactam allergy are practiced. Development of practice guidelines by our professional organizations may be useful.

The influence of polyethylene glycol and fine particles of zeolite on ionic conductivity of Hydrin-LiBF4 electrolytes and the exchange current density of the lithium electrode reaction has been studied by using impedance spectroscopy and cyclic voltammetry. The specific conductivity of the elastomeric electrolyte is about 10(-5) S cm-1 at room temperature when polyethylene glycol is present. But the mechanical stability of the film is less. The addition of zeolite particles to the elastomers also improves the specific conductivity. When present in low concentrations, the zeolite particles show catalytic effect on the electrochemical reaction at lithium electrode at ambient temperature. The lithium electrode reaction is reversible and the electrolyte possesses good electrochemical stability. C1 UNIV DAYTON,RES INST,DAYTON,OH 45469.

A hybrid strain controlled loading mode was employed for this purpose. This hybrid control mode did not allow the specimen to experience compressive stress in order to prevent any possible buckling effects. To fully understand the fatigue behavior of the MMC under this control mode, fatigue tests, microscopic evaluation, and micromechanical analysis were performed. Based on this combination of activities, the damage and deformation mechanisms were systematically identified. It was found that the fatigue behavior was initially dominated by creep deformation of the matrix. This was accompanied by plastic deformation in those specimens that were subjected to a maximum strain level of 0.55% or higher. Depending on the maximum strain level, the specimen failure was a result of either fiber fracture or matrix cracking. Using the combined approach involving experiments, microscopy, and analysis, the interrelationships among applied strain levels, fatigue life, damage mechanisms, and macroscopic response were established to characterize the longitudinal fatigue characteristics of the tested MMC.

Ketones containing a trifluoromethyl group as well as higher molecular weight perfluorinated substituents have been studied under different experimental conditions. The yields of tertiary alcohol is influenced by the solvents, reaction temperatures, type and concentration of metal fluorides, and structures of the fluoroalkyltrimethylsilanes and fluoroketones. The reaction has been extended to carbonyl compounds other than ketones. While a perfluorinated secondary acid fluoride gave good yield of the ketone, no reaction was observed with esters.

For this purpose, an updated version of the assimilative mapping of ionospheric electrodynamics technique has been used. These global patterns are unobtainable from any single data set. The period under study was characterized by a relatively stable southward interplanetary magnetic field (IMF), so that the obtained electric field patterns do reflect, in general, the state of sustained and enhanced plasma convection in the magnetosphere. During one of the satellite passes, however, an intense westward electrojet caused by a substorm into the satellite (DE 2) and radar (Chatanika, Alaska) field of view in the premidnight sector, providing a unique opportunity to differentiate the enhanced convection and substorm expansion fields. The distributions of the calculated electric potential for the expansion and maximum phases of the substorm show the first clear evidence of the coexistence of two physically different systems in the global convection pattern. The changes in the convection pattern during the substorm indicate that the large-scale potential distributions are indeed of general two-cell patterns representing the southward IMF status, but the night-morning cell has two positive peaks, one in the midnight sector and the other in the late morning hours, corresponding to the substorm expansion and the convection enhancement, respectively.

The methylene carbon undergoes scalar relaxation of the ''second kind'' as it is coupled to a faster relaxing (quadrupolar) nucleus. Dimeric EtAlCl(2) undergoes a significant ''self-perturbation'' or liquid-state phase change between 50 and 60 degrees C, as evidenced by observed changes in its relaxation properties and J(AlC). The J(AlC) coupling constants are 191 (30-50 degrees C) and 165 (55-70 degrees C) Hz. A liquid-state quadrupolar coupling constant (chi) of 71.9 MHz is determined for the EtAlCl(2) dimer using the dual spin probe method, assuming that the asymmetry parameter of the electric field gradient (eta) is zero.

Methods: We prospectively enrolled 193 healthy term-gestation neonates with no identifiable perinatal risk factors for sepsis. At 4 hours of age a blood sample was collected by warmed heel stick. An automated Coulter complete blood cell count and a 100-cell manual differential leukocyte count were performed on each sample. The differential count was performed by a single hematopathologist unaware of the clinical status of each infant. Perinatal factors were identified by review of the mothers' and infants' hospital records. Results: The mean ratio of immature to total neutrophils was 0.16 (SD 0.10), and the 10% to 90% range was 0.05 to 0.27. The mean leukocyte count was 24.06 X 10(9)/L. (24,060/mm(3)), and the 10% to 90% range was 16.2 to 31.5 X 10(9)/L. (16,200 to 31,500/mm(3)). Neutropenia, <1.5 x 10(9)/L (1500/mm(3)) segmented plus band form neutrophils, was not observed. Of all the perinatal factors studied, only the duration of stage 1 labor was found to be associated with significant elevations in the leukocyte and absolute neutrophil counts. Conclusions: Previously published normal ranges for leukocyte indexes in healthy newborn infants during the early neonatal period are too restrictive; reference standards should be broadened.

The depths of most of these hydrophones are near the depth of the sound channel axis but some are considerably deeper. All are bottom mounted. Signal-to-noise ratios were found to be surprisingly high. Averaged over the continuous wave (cw) transmissions and in a l-Hz band, signal-to-noise ratios for the axial hydrophones south of the island range from about 19 to 30 decibels (dB), adjusted to a source level of 220 dB (referenced to 1 mu Pa at 1 m). The average signal-to-noise ratio for a hydrophone at a depth approximately 0.8 km below the axis is about 16 dB, suggesting acoustic energy was not restricted to a narrow interval in depth centered about the sound channel axis as had been anticipated. The travel time of the earliest arrival was found to be about 1 h, 44 min, 17 s. A late, scattered signal was observed for at least 23 min after termination of the direct signal. An unexpected combination of phase stability and amplitude variability was observed in the received signals. Continuing analysis of the Ascension data set is likely to provide considerable information about the characteristics of acoustic signals that have propagated global distances.

Wayner's theoretical treatment of evaporating thin films is applied to the problem of an evaporating extended meniscus within circular or slotted pores. In this application of Wayner's model, the nondimensional momentum equation is uniquely scaled in terms of the capillary number, to justify the use of the static meniscus curvature as a boundary condition for the extended meniscus profile even for the dynamic evaporating conditions studied herein. This boundary condition for small capillary numbers is consistent with (he observation of the nearly constant meniscus curvature with evaporation rate that the thin film must asymptotically approach. From these basic tenets, the mechanical and thermal behavior of a stably, evaporating, nonisothermal extended meniscus is predicted. The resulting predictions are qualitatively consistent with the experimental findings of Wavner and the previous theoretical studies. They further support the claims that for the cases studied herein, both thermocapillary stresses and vapor recoil stresses at the liquid-vapor interface are negligible. However, scaling arguments are presented that identify the conditions necessary for these terms to be important. C1 IBM INC,CTR THERMAL ENGN,TUCSON,AZ 85741. WRIGHT LAB,WRIGHT PATTERSON AFB,OH 45433.

The objective is to identify flow features that lead to the onset of surge as the fundamental pumping system instability. Results show that there are primarily two reasons for the onset of surge as the flow is reduced in the pump studied: (a) adverse flow in the tongue region, (b) destabilizing effect of the pipe diffuser. The former is due to premature diffusion of the flow entering the tongue region, which is manifested by increased flow recirculation through the tongue/impeller gap and flow separation on the volute outer side-wall opposite the tongue. These effects in the tongue region flow coupled with the destabilizing behavior of the pipe diffuser lead to the eventual unstable pump operation. C1 USAF,WRIGHT LAB,WRIGHT PATTERSON AFB,OH 45433.

Feelings and attitudes of personnel in the 12th Contingency Hospital were measured with a survey questionnaire in October 1990, 3 months prior to the mobilization date. The same questionnaire was administered in June 1991, about 2 months after the unit was demobilized. Indicators of increased tension, fear, and discouragement changed dramatically in the pre- and post-activation surveys. Some interesting rank group findings were noted. Results of the surveys point the way toward future studies to better understand what the specific emotional aspects of mobilizing a Reserve unit are and what can be done to ameliorate negative factors and to enhance constructive coping with problem areas.

Although many studies have related various measures of pulmonary function to post-operative outcome, there has been no study designed to determine which of the spirometric measures of pulmonary function tests reflects the actual abstract idea of pure pulmonary function. A homogeneous population of 70 male patients was subjected to pulmonary function tests and a simple stair climb. Measures of pulmonary function (including FEV1, FEV1%, FVC, FVC%, and MVV%) were factor analyzed in a measurement model of pulmonary function to obtain reliability and validity estimates in predicting performance on a simple stair-climb test. The analysis revealed several interesting aspects concerning the relative importance of the various spirometric measures of pulmonary function tests. The validity estimates of the pulmonary function measures were as follows: FEV1% = 0.917; FEV1 = 0.886; MVV% = 0.769; FVC% = 0.715; FVC = 0.694. Analysis indicates that the FEV1% was the single best spirometric indicator of pulmonary function when predicting the physiologic outcome (followed closely by the FEV1). In addition, the various spirometric measures of pulmonary function were not equally valid nor interchangeable in such analysis. Although the number of stairs climbed correlates well with pulmonary function (r = 0.626), the coefficient of non-determination (i.e., 1 - r2) suggests that about 61% of the performance on the stair climb may be explained by other parameters (i.e., cardiac function, determination, altitude, etc.).

Photographic measurements of the head tilt of 70 subjects were made, along with measures of sighting dominance and vertical misalignment during sighting. The analyses revealed that photographically measured head tilt is significantly associated with vertical imbalances during sighting and with sighting dominance. These data support the theory that motoric dominance in humans is partly related to mechanisms underlying postural asymmetry.

However, the correction provided by adaptive optics cannot restore diffraction-limited performance, due to discretized spatial sampling of the wavefront, limited degrees of freedom in the adaptive-optics system, and wavefront sensor measurement noise. Field experience with adaptive-optics imaging systems making short-exposure image measurements has shown that some of the images are better than others in the sense that the better images have higher resolution. This is a natural consequence of the statistical nature of the compensated optical transfer function in an adaptive-optics telescope. Hybrid imaging techniques have been proposed that combine adaptive optics and postdetection image processing to improve the high-spatial-frequency information of images. Performance analyses of hybrid methods have been based on prior knowledge of the ensemble statistics of the underlying random process. Improved image-spectrum SNRs have been predicted, and in some cases experimentally demonstrated. In this paper we address the issue of selecting and processing the best images from a finite data set of compensated short-exposure images. Image sharpness measures are used to select the data subset to be processed. Comparison of the image-spectrum SNRs for the cases of processing the entire data set and processing only the selected subset of the data shows a broad range of practical cases where processing the selected subset results in superior SNR.

There are two methods of acheiving such a vascularized osseous reconstruction: microvascular bone transfers and pedicled osseous flaps. Although microvascular composite grafts allow a greater quantity and variety of bone to be moved to the reconstructive site, pedicled osseous flaps remain an excellent reconstructive option. Pedicled osseous flaps are not technically complex, result in minimal donor site morbidity, and demonstrate acceptable reliability in selected cases. This article reviews the realm of pedicled osseous flaps that can be used in craraofacial reconstruction. Although infrequently employed, these useful flaps should remain in the armamentarium of the head and neck surgeon.

It is entirely possible that within the next 10 years the majority of bone grafting in craniofacial surgery may be done with biologically active synthetic materials rather than natural bone sources. At present, we have a large number of synthetic options for craniofacial skeletal augmentation and reconstruction that in many respects are superior to autogenous bone grafts. This article reviews those synthetic bone graft substitutes that currently have clinical application in facial plastic and reconstructive surgery, and touches upon new biomaterials that should prove even more useful in the future.

One factor associated with the poor ductility of TiAl is an apparently large Peierls stress, or lattice friction stress for the glide of ordinary (1/2[110]) dislocations. This Peierls relief is intimately related to the underlying crystal and electronic structure of TiAl, and specific bonding states have been identified by some investigators as contributing to the pinning of dislocations along certain line directions. In this study we qualify the relative strength of these bonds using several complementary electronic structure methods. Aspects of the electronic structure, equilibrium lattice constants and bond energies of gamma-TiAl are compared with hypothetical f.c.c. Ti as obtained by the full-potential linearized augmented-plane-wave (FLAPW) method, the DMol molecular cluster method and the linear muffin-tin orbital (LMTO) Green function (GF) method. Pair energies, bond occupations of Ti-Ti and Ti-Al bonds in L1(0) TiAl and f.c.c. Ti are calculated using the LMTO GF method. Comparing the d(xy) bonding states for these two crystal structure, we find the in-plane directional d-d bonding between Ti atoms on the (001) plane are strengthened in TiAl relative to f.c.c. Ti. These observations suggest that the alternating (001) planes of Al and Ti atoms presented in TiAl enhance these bonding states. Conversely, transition-metal ternary additions substituted on the Al sites in TiAl are expected to weaken these bonding states. Using the FLAPW method, we examine the changes in charge density in the Ti(001) planes when Mn atoms are substituted on Al sites in TiAl. Finally, LMTO GF methods are used to study the effect of Mn substitutional point defects on the Ti(001) d(xy) bonding states. C1 UES INC, DAYTON, OH 45432 USA.

A small-amplitude vortical disturbance is introduced at the upstream boundary and the governing equations solved time accurately to evaluate the spatial and temporal growth of the perturbations leading to instability waves [Tollmien-Schlichting (TS) waves] in the boundary layer. The effect of disturbance amplitude, orientation, and the effect of the leading edge and of surface curvature are investigated for the case of spanwise vorticity. Simulations reveal, for the conditions considered, a linear variation in the TS response with forcing amplitude for perturbations of free-stream velocity that are either symmetrical or asymmetrical with respect to the basic-state stagnation streamline. The presence near the leading edge of a large, oscillating component of velocity normal to the airfoil axis for the case of asymmetrical forcing results, for the same strength of input disturbance, in an increase in the TS response aft of the juncture and in the appearance of a superharmonic component of the disturbance motion near the tip of the nose. This superharmonic decays rapidly in the streamwise direction. In all cases considered, the first clear appearance of the TS mode occurs aft of the surface pressure-gradient maximum. Changes to the geometry that increase the maximum in steady surface pressure gradient are found to increase receptivity. C1 ARIZONA STATE UNIV,DEPT MECH & AEROSP ENGN,TEMPE,AZ 85287.

Recent research has demonstrated that rate-limited sorption and desorption of these compounds can have a profound impact on the concentration reductions achievable by SVE. In this note, one-dimensional equations presented by Brusseau (1991), which describe rate-limited transport of sorbing organic compounds in the vadose zone, are modified to model a SVE remediation at an idealized site and analytically solved. The analytical model presented herein describes transport of a sorbing organic contaminant in a converging radial flow field in the vadose zone, with sorption rate limitations described by first-order rate expressions. The model equations are solved in the Laplace domain and numerically inverted to simulate contaminant concentrations at an extraction well. A Laplace domain solution for the total contaminant mass remaining in the vadose zone is also derived. It is shown that under certain conditions, rate-limited sorption can have a significant impact upon SVE remediation in the vadose zone. The solutions presented in this note may be useful in verifying numerical codes which are being developed to model organic transport in the vadose zone under conditions of rate-limited sorption.

Low temperature mobilities of up to 70 000 cm2/Vs at carrier concentrations of 6.5x10(11) cm-2 were observed in a 20 angstrom quantum well. The results are compared with the theory of interface roughness scattering which indicates extremely smooth interfaces; however, discrepancies between experiment and theroy are observed.

Monitoring of the plasma process by optical emission spectroscopy indicated that the dominant species in the glow discharge was CF2. Studies of bulk polytetrafluoroethylene (PTFE) and plasma-polymerized fluorocarbon thin-film samples in an XPS system demonstrated that the formation of non-CF2 species can be induced by ion bombardment of CF2 molecules. Characterization of the deposited fluorocarbon films by XPS found that the F/C ratio and CFx distribution (O < x < 3) in the films were dependent on processing conditions. Fluorocarbon films deposited simultaneously onto Al, glass, steel, and PTFE substrates using a C2F6 plasma and a graphite sputter target had measurably different F/C ratios, with the F/C ratio of the films deposited onto the Al substrates consistently lower than the F/C ratios of the films deposited onto the other substrates. When a C2F6 plasma was used without a graphite target, the F/C ratio in the film was constant, but the CFx distribution was different for each of the substrate materials. Analysis of the plasma-polymerized films by TEM revealed that localized growth of fluorocarbon particles occurred during the initial stages of deposition, consistent with an activated growth mechanism. Differences in the F/C ratio for films deposited onto the various substrate materials were attributed to the interaction of the fluorocarbon plasma with the exposed surface of the substrate prior to complete coverage by the polymeric film.

Film properties could be adjusted by controlling substrate temperature and by laser or thermal anneals. X-ray photoelectron spectroscopy, glancing angle XRD, Raman spectroscopy and high-resolution scanning electron microscopy were used to evaluate film chemistry, crystallinity and morphology. Films grown at room temperature were amorphous, near stoichiometric, and had a multiplicity of chemical states. Local order and bonding were improved most dramatically through post-deposition laser anneals. Crystallite size could be increased by raising the substrate temperature during deposition and, to a lesser degree, by post-deposition thermal anneals. Local disorder was observed within the larger crystallites compared to those that were laser annealed. Crystallinity was induced in amorphous films by mechanical rubbing at room temperature under conditions where frictional heating was negligible. The degree of control over film properties provided by PLD demonstrates its value for growing/designing tribological coatings. C1 RAMSPEC RES,DAYTON,OH 45431.

Gas-atomized powder was by consolidated hot isostatic pressing at a low temperature (1010-degrees-C) to retain a fine microstructure. Samples of this material were upset isothermally at temperatures between 1000 and 1260-degrees-C and strain rates between 10(-3) and 10(-1) s-1. The stress-strain curves revealed moderate amounts of flow softening which were attributed primarily to dynamic recrystallization and secondarily to deformation heating (at the highest strain rate studied). The absence of large lamellar colonies in the powder metallurgy (PM) material was deduced to be the reason for peak flow stresses which were much lower than those previously noted for cast plus hot isostatically pressed Ti-48at.%Al-2at.%Cr-2at.%Nb. As for ingot metallurgy near-gamma titanium aluminides, the flow stress and grain size showed a strong dependence on temperature and strain rate. The steady state flow stresses for the PM alloy were almost identical with those for cast plus hot isostatically pressed and for cast plus hot isostatically pressed plus isothermally forged Ti-48Al-2Cr-2Nb. The PM materials also revealed a noticeable degree of microstructure non-uniformity which persisted even after hot-compression testing at various sub-a transus temperatures.

This emission is identified as H-band A, resulting from an indirect excitonlike transition in real space. The exciton is made up of a two-dimensional electron in the interface notch and a valence-band hole in the neutral region, having a binding energy of 1.8 meV. The H-band A exciton is directly excited by a free exciton making a vertical transition in real space. H-band A may be a distortion of the vertical direct free exciton in real space to an indirect free exciton in real space, in which case only one exciton is involved; or it could result from the direct excitation of the indirect exciton in real space by the vertical exciton through wave-function overlap, with energy and momentum being conserved. In the latter case two excitons are involved. While the exact coupling mechanism between the free exciton and the H-band A exciton is not well understood, two possibilities are suggested.

The present investigation was undertaken to extend these findings by characterizing the effects of various classes of 5-HT receptor ligands on the extracellular glutamate concentration in the SCN. Localized SCN application or i.p. injection of the 5-HT1A receptor agonist, 8-OH-DPAT, during the dark phase (6 h after lights-off) significantly reduced the extracellular glutamate concentration in the SCN region from baseline levels (38.7 +/- 8.7 and 53.4 +/- 11.2%, respectively, of pretreatment values; P < 0.05). The effect of systemically applied 8-OH-DPAT was abolished by i.p. injection of the 5-HT1A receptor antagonist, NAN-190, administered 20 min before the 8-OH-DPAT. Localized perfusion of the SCN with the 5-HT1B receptor agonist, TMFPP, also reduced extracellular glutamate but to a lesser degree than 8-OH-DPAT (80.1 +/- 3.9% of pretreatment levels; P < 0.05). This effect was prevented by i.p. injection of the non-selective 5-HT receptor antagonist, metergoline 20 min before TFMPP perfusion. Localized perfusion of the SCN region with the 5-HT2 and 5-HT3 receptor agonists, alpha-methyl 5-HT and 1-phenylbiguanide, respectively, had little effect on extracellular glutamate (both P > 0.1 vs. baseline). Systemic treatment with NAN-190 alone had little effect on extracellular glutamate, however, similar treatments with metergoline or the 5-HT2 receptor antagonist, ritanserin, induced significant increases extracellular glutamate levels. Together, these results point to a role for the 5-H(T1)A-like receptor (possibly 5-HT7) and to a lesser degree the 5-HTB receptor in regulating extracellular glutamate concentrations in the SCN. The physiological significance of such a role could be relevant to the modulation of EAA neurotransmission in the circadian pacemaker. C1 KENT STATE UNIV,DEPT BIOL SCI,KENT,OH 44242.

The pursuits of an autonomous control system for such nonlinear structures have led to the use of artificial neural networks. In the present paper, we propose the use of radial basis function networks as a learning controller to achieve vibration suppression and trajectory maneuvering. The ability of connectionist systems to approximate arbitrary continuous functions provides an efficient means of modeling, identification and control of complex systems. Based on the model reference adaptive control architecture, a neural controller learns to function as a closed-loop compensator and to force the dynamics of the nonlinear plant to match a given reference model. This paper addresses the theoretical foundation of the architecture and demonstrates its applicability via several examples.

The asymptomatic status of the sample and the structured nature of the referral process minimize the methodologic problems normally associated with studies of patients undergoing angiography. Cases (n = 24) had some angiographic evidence of coronary artery disease, whereas controls (n = 25) were found to have no evidence of occlusion. An interaction was observed between smoking history and a measurement of hostility based on observations of the respondent's behavior during a standard interview. Among nonsmokers, cases had higher hostility scores than did controls (p = 0.004). This association was not present among smokers. Self-reported hostility did not discriminate cases from controls. These findings support the notion that hostility plays a role in the pathogenesis of coronary atherosclerosis and point to the potential importance of interactions between hostility and other risk factors.

Chromatography is the separation of a complex mixture into its individual compounds through partitioning between a mobile phase and a stationary phase. A highperformance liquid chromatograph consists of mobile-phase reservoirs, pumps, a mixer to mix the solvents, a valve into which the sample is injected, a guard column, a column containing the stationary phase, a detector, and a recorder. Once compounds have been separated in the column, they pass into the detector, where an electronic signal corresponding to the amount of compound present is recorded as a peak in a chromatogram. The most common detection method is ultraviolet and visible light spectroscopy. Key concepts in HPLC theory are retention time, the time from injection of the sample to detection of a peak; capacity factor, a measure of retention corrected for the elution of an unretained compound; resolution, a measure of how well two peaks are separated; the selectivity of the method; efficiency, or resolving power; and the degree of symmetry of the peaks produced. Most HPLC separations are performed in the reverse-phase mode, which involves a nonpolar stationary phase and a largely polar mobile phase. Other modes are normal phase, ion exchange, and size exclusion. Before a drug stability study is carried out, an HPLC method must be developed that suits the needs of the proposed experiment. A thorough literature search is essential. Literature procedures serve as useful starting points but may require a great deal of manipulation. After the HPLC separation has been performed, it is necessary to validate the method used. It must be proved that the method is stability indieating, that the chromatographic standards were properly prepared, that the standard curve is acceptable, and that the method is both precise and accurate. Pharmacists who ensure that reliable, reproducible HPLC methods are used throughout studies of drug stability will obtain sound data that may be of great value in pharmacy practice.

Four commercially available ceramic brackets were evaluated. The brackets included both polycrystalline and monocrystalline types with either chemical or mechanical retention in the bracket bases. The ceramic brackets were bonded to one hundred and twenty bovine teeth, using Concise. The brackets were stressed until bond or bracket failure occurred with either shear, tensile, or torsional forces on the Instron machine. The maximum bond strength and the site of bond failure was recorded. Starfire TMB brackets fractured 30% of the time during shear debonding, whereas, Quasar 1000, Lumina, and Transcend 2000 brackets exhibited no bracket fractures. The shear bond strengths of Quasar 1000 brackets were significantly higher than Starfire TMB brackets. Starfire TMB was the only bracket type that exhibited no bracket fractures with tensile force. Tensile bond strengths were not significantly different between the four bracket types. In torsion, Lumina was the only bracket type that did not exhibit any bracket failures. Shear and tensile bond strengths of chemically retained brackets were not significantly different than mechanically retained brackets. Torsional bond strength of chemically retained brackets was significantly higher than mechanically retained brackets. The results suggest Quasar 1000, Lumina, and Transcend 2000 are best removed with shear or tensile forces. Starfire TMB is best removed with tensile forces.

Included were 164 primary acoustic tumor surgeries performed between 1988 and 1991 in patients with normal preoperative facial function; postoperative House-Brackmann facial function grade available immediately postoperatively; at time of discharge and at 1 year or more postoperatively; and a tumor 1.5 cm or smaller. There were 116 translabyrinthine surgeries and 48 middle fossa surgeries. There was no significant difference in facial function results between the two surgical approaches at any of the three postoperative time intervals. Immediate postoperative facial function grade I or II was present in 90 percent of patients who underwent the middle cranial fossa approach, and in 90 percent of those with translabyrinthine surgery. By long-term follow-up, grade I or II function was recorded after 96 percent of middle fossa, and 91 percent of translabyrinthine surgeries. Results were similar when evaluating subgroups of those with tumors measuring 1.0 cm or smaller and 1.1-1.5 cm. There was also no difference in facial function result between superior and inferior vestibular nerve tumors with either approach. The authors conclude that, in an experienced center, long-term postoperative facial function outcome is not a basis for selecting surgical approach for tumors measuring 1.5 cm or less.

The purpose of this prospective study was to determine whether higher physical performance requirements adversely affected outcome in a chronic pain rehabilitation program. Twenty-three active duty, chronic pain patients were treated along with 22 civilian chronic pain sufferers in a behavior modification, including positive, verbal reinforcement for performance, stress management and family counseling, physical reconditioning, including stretching, strengthening and aerobic conditioning in a slowly progressive fashion to required needs, and narcotic and muscle relaxant detoxification program at a major military medical center, Eighteen patients in each group, representing, respectively, 78 and 82% of the military and civilian participants, successfully completed the inpatient program. Success was defined by (1) elimination of all narcotics and minor tranquilizers, (2) elimination of all physical restrictions that precluded any desired work or play, which required much higher levels for the active duty patients that included: (3) elimination of all physical profile restrictions and (4) objectively passing annual aerobics field test requirements before the program's end. Review of military disability separation records, averaging 24 mo posttreatment, showed that no formerly successful active duty patients had later been discharged because of physical impairments. Of individuals responding to mail questionnaires at an average of 19 mo postprogram, 12 of 14 (86%) initially successful military patients reported continued unrestricted maintenance of physical abilities, whereas 10 of 14 (71%) of the initially successful civilians reported no restrictions in desired activities. In both the active duty and civilian chronic pain patients, regardless of the degree of physical requirements, 80% were rehabilitated to their required levels of performance to eliminate all disability, with reasonable attrition over time; This data suggest that arbitrary physical limitations often may not be necessary. Such restriction may better define a lack of adequate rehabilitation than physiologic limitations for most chronic pain patients. C1 WILFORD HALL USAF MED CTR,PSCPO,SAN ANTONIO,TX 78236.

Bacterial cells growing on 2-nitrotoluene released nitrite into the growth medium. The isolate also grew on 3-methylcatechol, 4-methylcatechol, and catechol. 2-Nitrotoluene, 3-methylcatechol, and catechol stimulated oxygen consumption by intact cells regardless of the growth substrate. Crude extracts from the isolate contained catechol 2,3-dioxygenase and 2-hydroxy-6-oxohepta-2,4-dienoate hydrolase activity. The results suggest that 2-nitrotoluene is subject to initial attack by a dioxygenase enzyme that forms 3-methylcatechol with concomitant release of nitrite. The 3-methylcatechol is subsequently degraded via the meta ring fission pathway. C1 ARMSTRONG LAB,EQCOL,TYNDALL AFB,FL 32403.

Moreover, we intend to show the trend for the reduction of this limit by introducing a medium with small refractive index and by using a longer wavelength. Although the BRDF typically describes the angular distribution of scattered light from surfaces, the expression describing the equivalent BRDF caused by the optical scattering from gas molecules in the optical path is derived through the use of the Rayleigh scattering theory. The instrumentation is described, and the experimental results of the equivalent BRDF caused by gas scattering from molecules in clear air, nitrogen, and helium gases are reported. These results confirm the trends of the prediction. C1 USAF, OFF SECRETARY, WASHINGTON, DC USA.

The NVG Test Lane, with its resolution chart, provides an effective cost-efficient method for aircrew members to quickly evaluate the correct positioning end focusing of their NVG's prior to each mission. This evaluation validated the ability of the NVG resolution chart to produce the same performance results as a more detailed psychophysical procedure. NVG visual acuity was measured for five subjects (four pilots and one non-pile,) with two different night vision goggles. The results supported that there is no statistical difference between the results obtained with the Individual target format and the 3 x 3 format. Additionally, the pilots with current NVG experience were able to obtain a significantly better acuity level than were those without current NVG experience. C1 UNIV DAYTON,RES INST,DAYTON,OH 45469.

Transbronchoscopic lung biopsy (TBLB) has been considered the procedure of choice when less invasive tissue samples are unavailable. A total of 51 consecutive patients suspected of having sarcoidosis underwent combined TBLB and flexible transbronchial needle aspirate (TBNA). In 18 of the 30 patients (60 percent) with stage I disease, the diagnosis was confirmed by TBLB and 16 (53 percent) were confirmed by TBNA. The combined use of both procedures increased the diagnostic yield to 83 percent. The remaining 21 patients with stage II disease had their diagnosis confirmed in 16 (76 percent) cases by TBLB and 10 (48 percent) by TBNA with a combined diagnostic yield of 86 percent. Seven (23 percent) patients with stage I disease and 2 (10 percent) with stage II disease had their conditions diagnosed by TBNA.

Solutions were computed assuming rotational symmetry and frictionless flow at the pipe wall. Both time-independent and time-varying (ramp to steady-state) vortex properties were specified at the inlet. Time-asymptotic solutions were found to be in agreement with results of calculations using the governing equations in steady-state form. However, where, as a function of vortex strength, multiple equilibrium solutions of the Navier-Stokes were admissible, time-asymptotic behavior was found to be sensitive to initial condition and the rate at which vortex strength was varied at the inlet. Time-asymptotic solutions either exhibited vortex breakdown (i.e., reversed flow was present) or were quasi-cylindrical in nature.

The present study quantitatively analyzed electroencephalograms (EEGs) from rats receiving this electrolytic treatment in order to characterize the resultant hippocampal seizure activity. To examine the epileptogenic role of ferric ion deposition to that of current-induced tissue destruction, we compared steel to platinum electrodes. Adult male rats were surgically implanted with a chronic recording electrode in the CA3 region of the hippocampus, and then (contralaterally) with either an insulated steel electrode in the hilus, platinum electrode in the hilus, or steel electrode in the medial entorhinal cortex. Each rat received an anodal current through the nonrecording treatment electrode while connected to a polygraph. Currents ranged from 0.8 mA, 7 s for hilus electrodes to 2.0 mA, 20 s for entorhinal cortex electrodes. EEGs were collected from alert, unrestrained rats for up to 50 consecutive hours, and additional EEGs were recorded periodically over a 4-day period. Subjects were sacrificed and brain sections were microscopically examined for evidence of neuropathology. The results demonstrate that electrolytic deposition of iron ions in the hilus, and not merely hilus tissue destruction, produce electrographic seizure activity within 1-2 fi of current passage. Seizures recurred most intensely for 2-3 h, and sporadic epileptiform activity was detected for up to 12 h. Motor seizures of class 4 or 5 were observed in all seizing rats, and were always coincident with hippocampal seizure discharges. Histological examination of brain sections from all subjects found no evidence of cell death in the contralateral hippocampus. The dentate gyrus appeared to be the most epileptogenic site tested because hippocampal iron deposition that did not include the dentate gyrus, or iron deposition in the entorhinal cortex, was significantly less epileptogenic.

The influence of the visual appearance of the terminal ileal mucosa on patient management was assessed subjectively. The cecum was reached in 270/295 (91%) patients, with successful terminal ileal intubation being accomplished in 213/270 (79%) examinations. The time required to intubate the terminal ileum (x = 3.4 minutes; range, 30 seconds to 10 minutes) was not significantly different (p < 0.05) between the several levels of training in our fellowship program. The terminal ileum was considered to be visually abnormal in 4 cases, but only 1 of these was abnormal on histologic examination. In this unselected population, routine ileoscopy was unrewarding for finding an incidental positive diagnosis; however, brief attempts at terminal ileal intubation may be useful to improve or maintain endoscopic skills, especially in a training setting.

Proton nmr and deuterium labeling of this heterocyclic compound reveals it is comprised of both meso and dl diastereomers caused from its two chiral carbon atoms. Because this heterocycle incorporates both gem-2,2-dinitroalkyl and cyclic trioxane acetal structural fragments into one hybrid saturated ring structure, a novel intramolecular electron impact stability comparison can be made between the structural features representative of the normally unrelated geminal polynitroalkane and cyclic polyoxane compound classes which determine the fragmentation pathway of the subject heterocycle.

However, little is known about which factors contribute to the sensitivity, validity, and reliability of subjective workload ratings. One major classification of subjective workload assessment tools is based on relative judgments of the workload of different task conditions. The present research evaluated different approaches to relative subjective workload assessment in terms of their sensitivity to demand manipulations, concurrent validity with performance, and test-retest reliability. Results indicated that performing relative judgments retrospectively after having experienced all task conditions was superior to rating each task condition immediately after performing it. Further, redundant relative comparisons may produce more sensitive ratings than do relative comparisons to a single reference task. Overall, the results support the use of retrospective relative workload judgments as an evaluation tool. C1 USAF,ARMSTRONG LAB,DIV HUMAN ENGN,WRIGHT PATTERSON AFB,OH 45433.

An integrated slot-ring element with two Schottky-Barrier diodes acts simultaneously as an antenna, and as a mixer. A nonlinear analysis has been performed of the mixer function. The slot-ring element receives RF and LO power through a hyper-hemispherical lens. This lens is also analyzed and radiation patterns are calculated, which are in good agreement with measurements. The results in this paper indicate that quasi-optical monolithic monopulse systems in the millimeter wave range, based on four slot-ring elements and a hyper-hemispherical lens, should have excellent performance.

PBMC and M phi from all these donor groups secreted increased levels of tumor necrosis factor alpha, interleukin-1 beta, and interleukin-6 in response to stimulation with formalin-killed spherules (FKS), as measured by enzyme-linked immunosorbent assays. Viable C. immitis spherules also stimulated PBMC and M phi from healthy subjects and patients to secrete tumor necrosis factor alpha, interleukin-1 beta, acid interleukin-6, although at levels lower than those induced by FKS. The production of these acute inflammatory cytokines may contribute to the immunopathogenesis of active coccidioidomycosis and could account for the toxicity of the FKS vaccine in humans.

The inner case, core, and outer case regions of the bearing cone are modeled bu three concentric rings. Using a mechanics of materials approach with the aid of some simplifying assumptions ( i.e., radial stresses remain zero throughout the ring thickness and net circumferential strain is the same for all three rings), the influence of temperature, interference fit stresses, initial case carburizing stresses, and stress relaxation on the change in bore diameter and circumferential stress during service could be determined. The model indicated that both thermal-induced transformation and low temperature creep may play a role in bore growth during service. As temperature was increased from 70 degrees C to 200 degrees C, the susceptibility to bore growth became greater. Also, an increase in the interference fit increased the initial cone bore growth rate. In addition, the effect of the recondition treatment on the bore diameter and residual stresses was studied. The bore diameter generally decreased during the recondition treatment, and this was attributed to the relaxation of residual stresses by low temperature creep.

This study suggests that these currents are originated from the electron and hole leakage through the dielectric-layer (e.g., polyimide, nitride, etc.) interface at the emitter-base and base-collector peripheries, as well as through the n+-subcollector/semi-insulating substrate interface. Five HBTs having similar intrinsic make-ups (i.e., doping concentration and layer thickness) but different extrinsic make-ups (i.e., finger pattern, perimeter, dielectric layer, etc.) are investigated, and with the aid of the model, the possible mechanisms contributing to their leakage behavior identified.

We examined whether the response to TGF-beta is mediated by protein kinase C activity in chondrocytes at different stages of maturation. The aims were to examine the effect of recombinant human TGF-beta(1) (rhTGF-beta(1)) on protein kinase C in rat costochondral chondrocyte cultures; determine the major isoform present; assess the involvement of phospholipase C or tyrosine kinases; determine whether genomic or nongenomic pathways are involved; and test whether these mechanisms differ as a function of the stage of cell maturation. Dose-dependent increases in protein kinase C activity were observed in confluent, fourth-passage cultures of rat costochondral growth zone and resting zone chondrocytes treated with rhTGF-beta(1). In growth zone cells, elevated activity was observed at 12 h and decreased markedly by 24 h. In resting zone cells, elevated activity was observed at 9 h, maximum stimulation occurred at 12 h, and activity returned to baseline levels after 48 h. Immunoprecipitation studies showed protein kinase C alpha is the major isoform present in both untreated and treated cells. Neither the phospholipase C inhibitor, U73122, nor the tyrosine kinase inhibitor, genistein, significantly reduced the protein kinase C response to rhTGF-beta(1). Actinomycin D and cycloheximide, inhibitors of transcription and translation, produced dose-dependent inhibition of rhTGF-beta(1) stimulated protein kinase C activity in both resting zone and growth zone chondrocytes. The time course of activation and insensitivity to U73122 suggest that phospholipase C-mediated events are not involved in rhTGF-beta(1) stimulation of protein kinase C in costochondral chondrocytes. Similarly, because genistein had no effect, tyrosine kinases are not implicated. Rather, the reduction in protein kinase C activity observed when rhTGF-beta(1) is administered along with actinomycin D or cycloheximide indicates that new gene expression and protein synthesis are required for the response. These results indicate that the effect of rhTGF-beta(1) is mediated by protein kinase C; however, it is very slow and may require new protein kinase C production, perhaps via a cytokine cascade. Moreover, the classic mechanism of activation of protein kinase C by phospholipase C was not found, suggesting a novel mechanism of activation. Finally, the effects of rhTGF-beta(1) on protein kinase C are dependent on the state of cell maturation with respect to onset and duration of response.

However, the high cost and low productivity of the current two-step InP crystal growth process remains a severe drawback to its commercial applications. This has motivated many researchers to propose and investigate an innovative scheme of one-step synthesis (by injecting phosphorus vapor into the indium melt) and growth of InP crystals by the liquid-encapsulated Czochralski or Kyropoulos technique. For this one-step process to succeed and produce single crystals of uniform quality, it is important to develop a basic understanding of the mechanisms of energy transport and gas flow in a high-pressure crystal growth (HPCG) system. A series of experiments is conducted to characterize the thermal coupling between the melt and the phosphorus injector and to develop an understanding of the buoyancy-induced flow in a HPCG furnace. The gas flow in a high pressure furnace is turbulent and oscillatory, but radiation dominates the heat transfer. Thermal response of the system is therefore quite stable and predictable. The correlation between temperatures at various locations of the phosphorus injector and the melt is very interesting. The heat of reaction also affects the melt temperature. The phase change phenomenon at the bottom of the phosphorus injector seems to be oscillatory in nature. Theoretical estimates of the strength of gas convection and radiation loss by the melt surface are also presented. C1 PARKE MATH LAB,CARLISLE,MA 01741. USAF,ROME LAB,BEDFORD,MA 01731.

Electrical characterization demonstrates ohmic behavior over a wide annealing temperature range from 300 to 700-degrees-C. A minimum contact resistance of 0.176 OMEGA-mm was measured after furnace annealing at 500-degrees-C. The contact resistance is also insensitive to anneal time at 500-degrees-C. Structural characterization using secondary ion mass spectroscopy, Auger electron spectroscopy, and x-ray diffraction indicates excess In as a potential cause of increased contact resistance following 700-degrees-C annealing.

A series of laboratory experiments was conducted in a two-dimensional, homogeneous sand pack with gas permeabilities ranging from 110 to 3,000 darcy. Pure methane gas was injected horizontally into the sand and steady-state methane profiles were measured. Experimental results are in close agreement with a numerical model that represents the advective and diffusive components of methane transport. Comparison of simulations with and without gravitational acceleration permits identification of conditions where buoyancy dominates methane transport. Significant buoyant flow requires a Rayleigh number greater than 10 and an injected gas velocity sufficient to overcome dilution by molecular diffusion near the source. These criteria allow the extension of laboratory results to idealized field conditions for methane as well as denser-than-air vapors produced by volatilizing nonanaqueous phase liquids trapped in unsaturated soil.

Experiment 1 established norms for supporting materials used in Experiment 2. Subjects in Experiment 2 learned an artificial (computer-based) environment that was either randomly- or prototypically-configured, then performed several tasks intended to assess their configurational knowledge of the environment. The results showed that subjects were able to derive configurational knowledge from either the random or prototypical configuration. However, configurational knowledge was better in the random condition than in the prototypical condition. It was also found that subjects' configurational knowledge was, in general, functionally similar to their knowledge of a real-world environment. Multidimensional scaling was used of distance-estimation data to reconstruct recognizable representations of the artificial environments from the data. Finally, no effect was found for the schema-expectancy of sites on the acquisition of configurational knowledge. RP REGIAN, JW (reprint author), ARMSTRONG LAB,HRTI,BROOKS AFB,TX 78235, USA.

A targeting law and navigation filter are developed assuming the traditional passive target-active chaser vehicle relationship. The targeting law is demonstrated using a small-radius translunar halo orbit and ideal navigation; the three-body terminal-phase rendezvous problem is then further characterized and contrasted with the two-body problem. Nonlinear simulation results validate the navigation filter design and provide data to assess the filter performance. To demonstrate the entire guidance and navigation system, two profiles for terminal-phase rendezvous were considered in a planar circular orbit and two equivalent profiles in an H-2 guided halo orbit.

The optical sensors cover the spectrum from the far ultraviolet through the longwave infrared (110 nm to 28 mu m). The Midcourse Space Experiment (MSX) satellite, funded and managed by the Ballistic Missile Defense Organization, will be a long-duration, observatory-style measurement platform that will collect several terabytes of high-quality data on earth, earthlimb, and celestial backgrounds, ICBM-style targets, and resident space objects. While the principal focus of MSX is to collect phenomenology data in support of ballistic missile defense objectives, it will also be capable of collecting cell-calibrated data in support of a variety of civilian science objectives in earth and atmospheric remote sensing and astronomy. This paper reviews the mission objectives, describes the spacecraft and the instrumentation, and discusses the planned observations. It also outlines an innovative approach to reducing, analyzing, and archiving the large database that will result from several years of data collection supporting a variety of scientific objectives.

We studied two patients with latent, decremental atrioventricular (AV) fibers in whom pre-excitation could be demonstrated only during wide complex tachycardia. Background. The presence of decremental AV fibers participating in antidromic AV reentrant tachycardia is usually suspected by the presence of pre-excitation either in sinus rhythm or during atrial pacing. Methods. Two patients were referred for evaluation and treatment of wide complex tachycardia whose configuration suggested ventricular tachycardia that could be terminated with adenosine infusion. They underwent standard electrophysiologic studies. Results. Baseline AH and HV intervals were normal. No pre-excitation was noted with atrial overdrive at multiple sites or during atrial extrastimulation. Retrograde conduction was present with a sequence compatible with AV node conduction. Sustained wide complex tachycardia was induced with ventricular overdrive pacing. Late atrial premature depolarizations during tachycardia pre excited the subsequent ventricular activation. Earlier atrial premature depolarizations delayed the subsequent ventricular activation. In one patient, early atrial premature depolarizations terminated the tachycardia without activating the ventricle. In the other patient, spontaneous tachycardia termination was accompanied by ventriculoatrial block The earliest ventricular activation was at the annulus in the posteroseptal region in one patient and at the left posterior region in the other. Atrioventricular node reentry and atrial tachycardia with bystander AV fibers were also excluded. These findings establish the diagnosis of antidromic AV reentrant tachycardia utilizing a slow, decrementally conducting AV pathway. Conclusions. This is the first report describing the presence of latent, decremental accessory AV pathways in which conduction was manifest only during antidromic AV reentrant tachycardia. To differentiate these wide complex tachycardias from adenosine-sensitive ventricular tachycardia, we recommend that atrial premature depolarizations be applied during tachycardia to rule out the presence of a latent, decremental AV fiber even in patients who do not otherwise have pre-excitation with atrial pacing techniques.

The numerical analysis employs a finite-difference technique to model photorefractive grating dynamics. The magnitude and the phase of the space-charge field are presented in detail as functions of modulation depth, fringe velocity, and crystal parameters. Energy transfer and diffraction efficiency are found to exhibit different response characteristics with modulation and fringe velocity. Numerical results for two-wave mixing are generalized through analytical expressions that approximate the numerical solutions. Illustrative experimental results are presented for Bi12SiO20.

It is similar to the linear characteristic (or, in slab geometry, the linear nodal) quadrature but differs by assuming an exponential distribution of the scattering source within each cell, S(x) = a exp(bx), whose parameters are root-solved to match the known (from the previous iteration) average and first moment of the source over the cell. Like the linear adaptive method, the exponential characteristic method is positive and nonlinear but more accurate and more readily extended to other cell shapes. The nonlinearity has not interfered with convergence. We introduce the ''exponential moment functions,'' a generalization of the functions used by Walters in the linear nodal method, and use them to avoid numerical ill-conditioning. The method exhibits O(DELTAx4) truncation error on fine enough meshes; the error is insensitive to mesh size for coarse meshes. In a shielding problem, it is accurate to 10% using 16-mfp-thick cells; conventional methods err by 8 to 15 orders of magnitude. The exponential characteristic method is computationally more costly per cell than current methods but can be accurate with very thick cells, leading to increased computational efficiency on appropriate problems.

This study compared the effect of various surface coatings on F release from glass-ionomer cement. Twenty glass-ionomer cement (Ketac-Fil Aplicap) disks (4.52 cm2) were prepared from a Teflon mold. The control group was uncoated, while the experimental groups were coated with Visiobond, Scotchbond II, and Ketac Varnish. In addition, five specimens of Variglass were similarly prepared and remained uncoated as per the manufacturer's instructions. F release was measured each day during week 1 and on the last day of weeks 2, 3, and 4. The results indicated that the application of the surface coatings did not completely inhibit F release from glass-ionomer cements, and that F release during the first week for all groups was significantly greater than in the subsequent 3 weeks. Visiobond-coated glass-ionomer cement allowed significantly more F release than Scotchbond II-coated glass-ionomer cement, Ketac Varnish-coated glass-ionomer cement, or Variglass.

This submicroscanning method involves using the beam steerers to shift images on a focal-plane array by a fraction of the amount used in typical microscan methods. Interpolation techniques based on interlaced sampling are used to produce images free of aliasing out to twice the Nyquist frequency determined by the focal-plane array. Since a continuous phase ramp is produced by the liquid-crystal beam steerer, dispersion effects due to the gratinglike nature of the devices are avoided. Simulations for both one- and two-dimensional cases are presented, as well as experimental results using a 3- to 5-mu m imaging sensor and a liquid-crystal beam steerer designed for operation at 1.064 mu m.

Rev. Lett. 84, 1196 (1990)]. We determine the controlling perturbation one or more cycles ahead of when it needs to be applied, thereby gaining the additional time necessary to measure a signal, determine the perturbation, and then implement it. Formulas for this method of prior iterate control are derived and their utility is demonstrated numerically on the Henon map for controlling the unstable orbits of period one and two, The effects of noise on this control method are examined and the results are compared with a similar application of the OGY scheme in the presence of noise.

It was found that, analogous to an inductive discharge, it can operate both in a capacitive and an inductive mode. However, in the helical resonator either mode can be selected for one gas pressure and at similar power simply by changing the operating frequency. This will produce an extended plasma for the capacitive mode and a plasma concentrated in the resonator for the inductive mode. The inductive mode is enhanced at higher power levels and higher pressures. The pressure range investigated ranged from 0.05 to 10 Torr. Electron densities were measured with a microwave interferometer both inside the resonator and downstream and reached 3 x 10(10) cm(-3) for 0.5 Torr argon at 0.075 W/cm(-3) rf power. The resonance characteristics were affected by gases such as N-2 and SF6. RP BLETZINGER, P (reprint author), USAF,WRIGHT LAB,WRIGHT PATTERSON AFB,OH 45433, USA.

Citrate also enhances lead absorption in animals. We questioned whether use of calcium citrate by women as a calcium supplement causes ain increase in aluminum or lead absorption from dietary sources. Changes in 24-hour urine aluminum and lead excretion, plasma aluminum level, and whole blood lead level were assessed in 30 healthy women before and during treatment with calcium citrate (800 mg of elemental calcium per day). During calcium citrate therapy, urinary aluminum excretion and plasma aluminum level increased significantly. In contrast, there were no changes in urine or whole blood lead levels. We conclude that treatment with calcium citrate significantly increases absorption of aluminum from dietary sources. Additional studies are needed to determine whether long-term use of calcium citrate leads to aluminum accumulation and toxicity. C1 WILFORD HALL USAF MED CTR,DEPT MED,LACKLAND AFB,TX 78236.

The wave-front sensor measurements are used to reconstruct an estimate of the instantaneous generalized pupil function of the telescope, which is used to compute an estimate of the instantaneous optical transfer function (OTF). This estimate of the OTF is then used in a deconvolution procedure. We point out the existence and origin of an unnoticed bias in the estimator for the DWFS method. This bias leads to nonrandom errors in the estimated object spectrum beyond those expected to arise by virtue of low-pass filtering and noise, including the possibility of an overall system transfer function greater than unity at some spatial frequencies. An alternative measurement and postprocessing scheme to overcome this source of error is suggested.

The application of a partially ionized oxygen plasma generated by passing the plume through a ring electrode facilitated stoichiometric film growth in low 02 partial pressures. Emission spectroscopy of the plume revealed an enhancement in the ionic and neutral excited Ge species. The concentration of excited neutral and ionic oxygen atoms also significantly increased when the ring electrode was activated at P(O2)>10 mTorr. Coupling the results of the film property measurements with the emission studies suggested that the presence of 0 atoms near the substrate surface during film growth was more critical in promoting oxidation than the gas phase process in the plume. The low-pressure conditions that were utilized to deposit stoichiometric film growth identified the appropriate conditions to produce uniform films over a large area that may be suitable for waveguide fabrication.

Pressure measurements were taken in the neural foramina of C5, C6, and C7 nerve roots at various positions of the head and ipsilateral arm in eight fresh cadavers. Objectives. The purpose of the study was to correlate clinical signs and symptoms with pressures generated in the neural foramen of patients with cervical radiculopathy. Summary of Background Data. The reliability of the clinical signs used to diagnose cervical disc herniations has remained controversial. Previous studies have shown the active relationship of the cord and nerve roots to the various movements of the spine. Methods. A standard anterior approach was made to the cervical spine and the C5-C7 roots identified. A balloon catheter, attached to a pressure transducer and monitor, was inserted in the neural foramen. The head was then taken through varying degrees of flexion and extension in combination with the arm neutral or abducted. Results. Increasing neck extension led to significant pressure changes at each root tested. With the movement of the arm from the neutral to abducted position, the pressure was significantly relieved. The results with neck flexion were variable. Conclusions. The significance of this study is that it offers an explanation for the clinical observation of increasing radicular symptoms with neck extension and relief of these symptoms with the shoulder abduction relief maneuver in the setting of a cervical radiculopathy.

The prevalence of human papillomaviruses (HPV) in KS has been the focus of several investigations that have reported conflicting data. In addition, mutations of the p53 gene, which are the most frequent genetic changes found in human tumors, are absent in HPV-positive cervical carcinomas leading to the hypothesis that the function of p53 in HPV-positive tumors is inactivated through binding to the E6 viral gene product. Thus, the present study was designed to investigate the presence of HPV and p53 gene mutations in 17 formalin-fixed, paraffin-embedded KS [7 acquired immunodeficiency syndrome-KS (AIDS-KS) and 10 classic KS] specimens. HPV 6 DNA was detected in an AIDS-KS specimen, and HPV 16 DNA was found in 3 classic KS specimens. Heterozygous mutations of the p53 gene were detected in five (24%) KS samples. No p53 mutations were detected in HPV-positive KS. The p53 mutations were mainly transversions (four of five). These data indicate that HPV may contribute to the pathogenesis of some cases of KS and that p53 alteration may represent a key event in the progression of the malignancy.

The wave-front sensor measurements are used to reconstruct an estimate of the instantaneous generalized pupil function of the telescope, which is used to compute an estimate of the instantaneous optical transfer function, which is then used in a deconvolution procedure. This imaging method has been called both deconvolution from wave-front sensor (DWFS) measurements and self-referenced speckle holography. We analyze the signal-to-noise ratio (SNR) behavior of this imaging method in the spatial frequency domain. The analysis includes effects arising from differences in the correlation properties of the incident and the estimated pupil phases and the fact that the object-spectrum estimator is a randomly filtered doubly stochastic Poisson random process. SNR results obtained for the DWFS method are compared with the speckle-imaging power-spectrum SNR for equivalent seeing conditions and light levels, It is shown that for unresolved stars the power-spectrum SNR is superior to the DWFS SNR. However, for extended objects the power-spectrum SNR and the DWFS SNR are similar. Since speckle imaging uses a separate Fourier phase-reconstruction process not required by the DWFS method, the DWFS method provides an alternative to speckle imaging that uses simple postprocessing at the cost of a wave-front sensor measurement but with no loss of SNR performance for extended objects.

The flows are simulated by solving the full three-dimensional Navier-Stokes equations on a moving grid using the implicit Beam-Warming algorithm. An assessment of the effects of numerical resolution and favorable comparison with experimental data suggest the computational approach captures the basic dynamics of the onset and initial stages of transient breakdown. The pressure gradient along the vortex axis is found to play a dominant role in the initiation of breakdown. A description of the three-dimensional instantaneous structure of the flowfield is provided for the first time using critical-point theory. The reversed-flow region in the vortex core is associated with pairs of opposite spiral/saddle critical points. At its onset, the vortex breakdown is fairly axisymmetric; however, as it proceeds upstream and a stronger jump takes place along the axis, asymmetric effects become important and culminate in the formation of a bubble-type breakdown. This bubble structure is open and contains within itself a pair of stagnation points that are diametrically opposed and that rotate in the same sense as the upstream swirling flow. These critical points suggest the existence of azimuthal disturbances in the breakdown region. The bubble sectional topology is also found in agreement with recent experimental measurements.

The purpose of this study was to evaluate whether significant cephalometric differences exist between adult Mexican-American, black American, and white patients. Lateral cephalometric radiographs were taken of 48 Mexican-American adults (23 men, 25 women). All subjects met the following criteria: parents, grandparents, or great-grandparents were born in Mexico; 18 to 50 years of age; Class I occlusion with minor or no crowding; good facial balance; no significant medical history or history of facial trauma; no previous orthodontic treatment or maxillofacial surgery. Twenty-five cephalometric measurements were analyzed. Significant racial and sexual differences were found in the following areas: skeletal measurement (SNA, ANB, Po-N perpendicular to, Co-A, Co-Gn, ANS-Me, MP-FH, MP-SN); dental measurement (U1-A perpendicular to, L1-APo, U1-L1, IMPA); soft tissue measurement (NLA, FCA, UFH (pu), ULL). Orthodontists and oral surgeons will find the cephalometric values of help in the diagnosis and treatment planning of potential orthognathic surgery patients. C1 USAF,CLIN MCCHORD,SGD,MCCHORD AFB,WA.

The resultant hydroquinone is subject to ring fission catalyzed by a dioxygenase enzyme. We have isolated a strain of an Arthrobacter sp., JS443, capable of degrading PNP with stoichiometric release of nitrite. During induction of the enzymes required for growth on PNP, 1,2,4-benzenetriol was identified as an intermediate by gas chromatography-mass spectroscopy (CC-MS) and radiotracer studies. 1,2,4-Benzenetriol was converted to maleylacetic acid, which was further degraded by the beta-ketoadipate pathway. Conversion of PNP to 1,2,4-benzenetriol is catalyzed by a monooxygenase system in strain JS443 through the formation of 4-nitrocatechol, 4-nitroresorcinol, or both. Our results clearly indicate the existence of an alternative pathway for the biodegradation of PNP. C1 ARMSTRONG LAB,AL EQC,TYNDALL AFB,FL 32403. UNIV SCRANTON,DEPT CHEM,SCRANTON,PA 18510.

The reddenings to 31 photoelectrically measured stars in the direction of the cluster were determined individually yielding a mean E(B-V)=0.10+/-0.02. Broadband UBVI CCD images were taken with a 512x512 CCD and included deep frames on the center, plus a 3x3 mosaic of the cluster. With this reddening the UB V 2-color diagram for the cluster does, not match the standard solar-metallicity 2-color diagram. The substantial UV deficiency requires the cluster to be metal rich. Regardless of the choice of reddening value, if we make the assumption of solar metallicity for the cluster we cannot simultaneously derive a consistent fit of the 2-color diagram to standard 2-color sequences and the color-magnitude diagram to published isochrones. A comparison with solar-metallicity isochrones provides only an upper limit of approximately 10 Gyrs for the age for the cluster.

Any reduction in goggle or visual performance which goes undetected can have a serious effect on flight safety and operational capability. Under controlled lighting conditions, a crewmember should be able to obtain the best possible goggle performance, and to determine if the goggle is functioning properly. These data represent a sample of 218 current USAF aircrew members representing all crew positions in both rotary and fixed-wing aircraft. Three measurements of goggle performance, expressed as NVG visual acuity, were obtained. The first measure, obtained after crewmembers adjusted the goggles with their usual adjustment methods, showed that they routinely obtain less than optimal acuity levels; i.e., averaging between 20/50 and 20/55. The second measure, taken when the NVG Resolution Chart was provided to augment their ''usual'' method of adjustment, showed improved performance; i.e., averaging 20/45. The third measure, taken following participation in an NVG Adjustment Procedures class, showed the greatest improvement, averaging between 20/35 and 20/40. In summary, it is reasonable to conclude that aircrew members who are able to obtain the best possible performance for their NVG's under controlled preflight conditions will obtain the best possible goggle performance under the widely varying flight conditions.

This article describes the creation and analysis of a 1 5,275-record database of flyer-physician interactions, recorded over several years from 18 U.S. Air Force Bases. A descriptive analysis presents the leading causes of outpatient morbidity as measured by total days disqualified for flying duties (downtime). Upper respiratory infection (URI)/cold/congestion was the leading cause of illness, representing 4,485/15,700 visits with a median downtime of 6 d, and with 90% of the flyers allowed back into the cockpit within 15 d. A diagnosis coding system was developed specifically for this project that differs from the standard International Classification of Disease-Revision 9 (ICD-9 CM) (1) nomenclature. The rationale for such an approach is discussed. C1 USAF,SCH AEROSP MED,BROOKS AFB,TX 78235.

This is a continual challenge as aerospace technology leaps ahead while the human factor remains relatively constant. However, several issues interfere with the smooth interaction between these communities: 1) perceptions that the research and operational communities have towards human subjects and pilots respectively; 2) the legal and ethical considerations involved in exposing individuals to risk; and 3) the ever-present personality dynamics involved in any decision-making process (e.g., returning individuals to a centrifuge panel or flying duty after a medically disqualifying incident). All of these factors influence decisions made in both communities, and how they interact with each other. It is a dynamic process that varies between countries, individual services (e.g., Navy vs Air Force), and even between different geographical locations within the same service.

However, there have been complaints that the procedure contains several incubation steps requiring 15 min of operator time. The authors were able to shorten this procedure to a single 5 min incubation without affecting assay sensitivity. Both procedures were performed on 45 known lupus anticoagulant positive specimens, 25 normal donors, eleven plasmas from patients with known factor VIII or factor V inhibitors and ten other specimens submitted for lupus anticoagulant or anticardiolipin antibody testing but without complete testing to confirm the presence of LA prior to testing with Staclot LA(R). Excellent agreement was observed between the two procedures with concurrence in 87 of 91 specimens (95.6%). Each method detected 39 of 45 LA positive specimens giving a sensitivity of 86.7%. This modification shortens technologist time by two-thirds without compromising assay sensitivity, which will allow for automation on commonly used coagulation analysers.

Design: Retrospective evaluation of clomiphene citrate (CC) challenge tests in women from a general infertility population who did and did not smoke cigarettes (part 1) and retrospective evaluation of the impact of smoking on pregnancy rates (PRs) in IVF among women with normal ovarian reserve (part 2). Setting: Large military tertiary care center. Patients: Sixty-five women who smoked cigarettes and 145 women who did not smoke cigarettes in the general infertility population (part 1) and women undergoing IVF for strict tubal factor infertility with normal ovarian reserve who did (n = 29) and did not (n = 73) smoke (part 2). Interventions: Clomiphene citrate challenge tests, composed of FSH levels on cycle days 3 and 10 with 100 mg of CC administered on cycle days 5 through 9. Main Outcome Measures: Comparison of the incidence of abnormal CC challenge test results between women who did and did not smoke, and comparison of peak E(2) levels, number of mature follicles, number of mature oocytes retrieved, fertilization rates, and total and ongoing PRs. Results: The incidence of diminished ovarian reserve was increased in women who smoked (8 of 65 [12.31%]) when compared with age-matched controls who did not smoke (7 of 145 [4.83%]). Among women with normal CC challenge tests who were undergoing IVF, there were no differences in peak E(2) levels, the number of mature follicles, the number of mature oocytes retrieved, fertilization rates, or total and ongoing PRs. Conclusion: Women who smoke have an accelerated development of clinically detectable diminished ovarian reserve. Additionally, the fact that women who smoke cigarettes with normal ovarian reserve have ovarian responses and PRs that are equivalent to age-matched nonsmoking controls suggests that diminished ovarian reserve may be a principal mechanism reducing fecundity among women who smoke cigarettes.

Characterizing the PLGR's accuracy in dynamic environments is of prime importance but testing also prescribes the evaluation of its ability to receive differential GPS corrections, real time, and its Electronic Counter Counter Measures. To meet these goals, the 46th Test Group provides the C-12 cargo aircraft for flight testing, an instrumented test van for mobile testing, the High Speed Test Track for high velocity testing, a UH-1 helicopter for rotor blade modulation testing, and special PC laptops for ground troop testing. All of these test capabilities utilize Holloman's well instrumented test environments with thousands of surveyed sites validated by the Defense Mapping Agency. This paper will emphasize the testing techniques that are helping to define Test & Evaluation methodologies for the changing world where Global Positioning with NAVSTAR is becoming a reality.

The guided weapon impacted within 6 meters of the target, demonstrating the potential of INS/GPS technology to significantly improve air-to-surface munitions strategies and tactics. This landmark flight was successfully followed by five additional drops with varying altitudes, downrange distances and weather conditions. OCD was designated an Air Force High Gear program, allowing streamlined acquisition and reporting procedures, in response to Operation Desert Storm experience highlighting the need for attacking high-value targets from high altitude in adverse weather. OCD met it's objective to build and demonstrate an INS/GPS weapon in an operationally representative environment. Results of the demonstration show there is low technical risk associated with development of INS/GPS munitions considered for the Joint Direct Attack Munitions (JDAM) program. This paper provides additional details on program objectives, system implementation, and test results. The focus of this paper will be on the implementation and performance of the integrated INS/GPS navigation system. C1 SVERDRUP TECHNOL INC,EGLIN AFB,FL. SOFTWARE TECHNOL & SYST INC,LOS ANGELES,CA.

Measurements were made in the pressure range from 0.5 to 7 Torr and at a rf power of 35 W into the plasma. The influence of different electrode materials on the H atom density close to the electrode surface and in the discharge volume was measured. The data shows that the radial density distribution, under our discharge conditions, is primarily determined by the plasma-surface interactions and not by the discharge current uniformity (or nonuniformity). We have clearly demonstrated the ability of this measurement technique to monitor in situ, plasma induced surface property changes.

Dispersion of the light emitted by the plume in a vacuum revealed emission from both neutral and singly ionized Ge atoms as well as neutral O atoms. The spatial variation showed that the ion concentration decreased exponentially from the target surface while the neutral atom number density reached peak intensities at distances of almost-equal-to 1.5-2.5 cm from the target surface. Interactions between the plume constituents and the ambient molecular oxygen increased the excited Ge atom and Ge ion populations in the plume and, most notably, significantly enlarged the excited O atom concentration over that produced directly from the ablation process.

Both g and s (the interaction of general ability and experience) were defined by scores on the first and subsequent principal components of the enlistment selection and classification test (the Armed Services Vocational Aptitude Battery). Multiple regression analyses, when corrected for range restriction, revealed that g was the best predictor of all criteria and that s added a statistically significant but practically small amount to predictive efficiency. These results are consistent with those of previous studies, most notably Army Project A (J. J. McHenry, L. M. Hough, J. L. Toquam, M. A. Hanson, & S. Ashworth, 1990). The study also extends the findings to other jobs and uses traditionally more acceptable estimates of g, application of effective sample size in cross-validation estimation, and new performance criteria.

We decided to investigate the effects of spaceflight on muscle by utilizing a well characterized myoblast cell line (L8 rat myoblasts) as cultured in the recently designed Space Tissue Loss Flight Module ''A'' (STL-A). The STL-A is a ''state of the art,'' compact, fully contained, automated cell culture apparatus which replaces a single mid-deck locker on the Space Shuttle, The L8 cells were successfully flown in the STL-A on the Space Shuttle STS-45 mission. Upon return to earth, reculturing of these spaceflown L8 cells (L8SF) resulted in their unexpected failure to fuse and differentiate into myotubes. This inability of the L8SF cells to fuse was found to be a permanent phenotypic alteration. Scanning electron microscopic examination of L8SF cells growing at 1g on fibronectin-coated polypropylene fibers exhibited a strikingly different morphology as compared to control cells. In addition to their failure to fuse into myotubes, L8SF cells also piled up on top of each other. When assayed in fusion-promoting soft agar, L8SF cells gave rise to substantially more and larger colonies than did either preflight (L8AT) or ground control (L8GC) cells. All data to this point indicate that flying L8 rat myoblasts on the Space Shuttle for a duration of 7-10 d at subconfluent densities results in several permanent phenotypic alterations in these cells.
