Application of weather radar to fallout prediction : final report by Pauline M Austin( Book )

5 editions published between 1961 and 1962 in English and held by 5 WorldCat member libraries worldwide

Excellent data were obtained on a variety of weather situations ranging from snowstorms in March to hail and thunderstorms in May. Signal intensity contours on both radars, RHI photographs, R-meter measurements and radiosonde soundings were made. Work was resumed on designing and building a sweep integrater for use with short pulse on the AN/CPS-9 radar. It is probable that frequency modulation rather than amplitude modulation will be employed. A tippingbucket rain gauge was built to operate on the outflow of the Hudson-Jardi gauge and thus monitor its operation. The rainfall data were greatly improved by this addition. The data reduction program and the analysis of storm structure are progressing satisfactorily. The computations on modification of fallout patterns by rain were slowed down by computer and program failures. (Author)
Application of radar to measurement of surface precipitation : Final report, 1 Sept. 1967 to August 1968 by Pauline M Austin( Book )

4 editions published between 1966 and 1968 in English and held by 4 WorldCat member libraries worldwide

Work in instrumentation was primarily concerned with installation of new radars and auxiliary equipment. The 10-cm WR-66 radar has an 18-ft parabolic dish which provides high resolution and sensitivity. The signal is averaged by a digital sweep integrator, range-normalized, and quantized into intensity levels which can be displayed on the scope in three shades of gray. A data processor for digital mapping in Cartesian coordinates has been designed. The instruments and techniques which have been developed and are now in operation have overcome many of the limitations in the earlier models. A comprehensive study of mesoscale precipitation patterns and their relation to marcroscale parameters, based on all the storms which occurred during 1962-1963, is in progress. These storms have been grouped according to synoptic type, and analysis of air mass storms and coastal cyclones has been completed. Some preliminary computations have been made on a numerical model for aggregation of snowflakes, a process of importance in the development of raindrop size distributions. (Author)

Band structure and electrical properties of amorphous semiconductors. Final report by David Adler( Book )

5 editions published between 1970 and 1973 in English and held by 4 WorldCat member libraries worldwide

The rf sputtering is complete and high-quality films are being prepared by integrated circuit photolithographic techniques. The films have proven very strain sensitive and somewhat sensitive to variations in composition. The effective charge of the ions in the amorphous state has been determined from previous NMR results. More detailed NMR experiments and EPR experiments are being planned, in order to test the recent theoretical models. Amorphous and crystalline Si2Te3 films have been deposited in preparation for a comparison of their electrical and optical properties. Thermal effects at low temperatures and the radial temperature distribution of a threshold switch in the ON state are being investigated. A review of recent work in the field is nearing completion, and a review of the possible switching mechanisms has been completed. The basic ban model for amorphous semiconductors has been generalized to include electron-electron and electron-phonon interactions. Accurate solutions of the thermal model for switching have been obtained and an explanation for optical switching has been proposed. (Author)

Cycle Study of a Mercury - Colloidal Electrofluid Dynamic Power Generator by Beatriz Fernandez Urquidi( Book )

1 edition published in 1974 in English and held by 3 WorldCat member libraries worldwide

The author presents a study of an Electro-Fluid-Dynamic power system using mercury as the working vapor and hydrogen as the fill gas. Viscous coupling between mercury vapor and hydrogen is assumed. A detailed study of the various components, and related efficiencies, of the system is made and expressions for their dependence on various system parameters are derived. The overall system efficiency is optimized and analytical expressions for the optimum values of the operating parameters are given. A sensitivity analysis is made to determine the effect, on the efficiency of changes in several system parameters. Numerical calculations are carried out using a simple computer program. The results of the calculations are shown in graphical and tabular form. As an illustration, a 12.5 KW output power generator is considered and the main design characteristics are presented
Stress-strain-time behavior of soil in one dimensional compression( Book )

2 editions published in 1963 in English and held by 3 WorldCat member libraries worldwide

Ground motion prediction formulas based upon elastic wave propagation in one-dimension (no strain transverse to the propagation direction) have been used widely in protective construction work. Actual soil materials exhibit many deviations from elastic behavior. This report assesses the probable influence of these non-elastic effects upon the accuracy of the above-mentioned prediction formulas, and upon the question of stress attenuation with depth. Three different models of soil behavior are assumed: a standard 3-element visco-elastic model (spring in series with spring-dashpot combination); a compacting model (straight line loading and unloading curves); and an ''elastic'' model in which any arbitrary shape may be assigned to the loading stress-strain curve. This report deals primarily with the first of these three models; the possible significance and probable importance of the third model are discussed briefly. By combining the theoretical and experimental results, it is shown that the elastic ground motion prediction formulas are generally valid (for cases where it is appropriate to think of one-dimensional motion); i.e. the possible effects of viscosity and inelasticity are no greater than uncertainties as to the order of magnitude of the compressibility of an in situ soil mass.

FACTORS AFFECTING DEPTH PERCEPTION by Whitman Richards( Book )

2 editions published between 1970 and 1971 in English and held by 3 WorldCat member libraries worldwide

The report describes ongoing work on certain factors that affect depth perception. Of particular interest is that a sizeable portion (30%) of the population are unable to make full use of the binocular parallax cue for judging the distance of objects. These individuals are said to be stereoanomalous. Work over the past year has shown that these individuals localize objects in space in a manner different from other individuals who possess the full stereoscopic capability. A considerable effort has been spent in developing a simple, portable test for diagnosing the presence of stereoanomalies. Tests based upon random dot patterns appear to be satisfactory. One important distinction that emerges concerns two separate systems for stereopsis in the normal observer: one sensitive to positional changes in depth, and a second parallel system that requires object motion
Study of Quantum Mechanical Effects in Deep Submicron, Grating-Gate Field Effect Transistors( Book )

4 editions published between 1986 and 1991 in English and held by 3 WorldCat member libraries worldwide

This research program investigates the effect of extreme submicron spatial modulation of the electrostatic potential on the transport of electrons in silicon and in III-V compound semiconductor devices. The test vehicle is the so called grating gate FET (GGFET). When made to move in a direction perpendicular to the potential modulation, i.e., perpendicular to the grating gate, electrons experience a surface superlattice (SSL) effect. When moving along the potential modulation electrons are restricted to only one degree of freedom and thus constitute a one dimensional system. The major accomplishments to date are in process technology and design of the devices. They are: (1) Double X ray/deep UV exposure of PMMA to simultaneously define fine and coarse patterns; (2) High temperature (950 C) anneal of Silicon wafer after delineation of tungsten conductor patterns, to eliminate x ray damage of silicon dioxide; and (3) Design of Gallium/Gallium Aluminum Arsenide structure for the implementation of the III-V GGFET. Keywords: MOSFET Semiconductors; Field effect transistors; X ray lithography
Research on the physical properties of marine soils( Book )

3 editions published between 1959 and 1962 in English and held by 2 WorldCat member libraries worldwide

This report describes in detail a method for quantitatively measuring fabric of clay. Wet clay is impregnated with a polyalcohol which permits grinding a very flat surface (without disrupting the original fabric) for quantitative X-ray measurement. In the specific procedure discussed, a Norelco diffractometer equipped with a pole figure device and a Geiger detector was employed to measure by reflection the diffracted intensity of selected peaks (002 and 020) on kaolinite clay. The amplitude of the 002 peak to the amplitude of the 020 peak is called the peak ratio which quantitatively expresses particle orientation on a given surface. Heterogeneity of particle orientation on a surface is expressed in terms of the observed standard deviation relative to the standard deviation expected from counting statistics for peaks of the appropriate amplitude
Role of Ser-Arg Proteins in the Regulation of RNA Processing( Book )

4 editions published between 1997 and 1998 in English and held by 2 WorldCat member libraries worldwide

Deregulation of alternative splicing has been linked to malignant transformation in breast cancers. Therefore, to fully understand breast cancer, it will be important to identify and characterize factors that regulate the splicing process. We have previously identified a complex of nuclear matrix proteins related to Serine/Arginine- repeat (SR) splicing factors which is required for the splicing of specific pre-niRNAs (Blencowe et al., 1998). This complex contains the SR-matrix proteins of l6OkDa and 3OOkDa (SRml6O and SRm3OO) which, unlike proteins of SR family of splicing factors, lack RNA Recognition Motifs (RRMs). This complex associates with pre-mRNA through multiple interactions involving SR family proteins and small nuclear ribonucleoprotein particles (snRNPs). During the past year, we have completed the sequencing of SRm3OO and have investigated the function of the SRml6O/3OO complex in regulated splicing. We have demonstrated that SRml6O/3OO is required for a purine-rich exonic splicing enhancer (ESE) to promote the splicing of a pre-mRNA containing a weak 3' splice site
Metabolic Response to Food Restriction in Military-Eligible Women, with a Gender Comparison by Vernon R Young( Book )

6 editions published between 1996 and 1999 in English and held by 2 WorldCat member libraries worldwide

Two major series of investigations will be undertaken to explore the metabolic responses of women, who meet military standards of body-weight and percent body-fat to the nutritional stressors of food restriction. A comparison of their responses will be made with those occurring in men, who also meet the standards established by the military. The first series (Series I) will be devoted to the temporal (Progressive) changes in lipid, carbohydrate and protein metabolism that occur during a short-term (3 day) fasting period. A proposed sixteen women and eight men will participate in this study. p5

We continued our project on the IOA language and toolset, which are designed to support our formal approach to distributed system design and analysis. The design of the IOA language is substantially complete, and appears in a language manual on the web. This quarter, work continued on the development of tools for the IOA language; our toolset will include a parser and static semantic checker, composition routine, support for levels of abstraction interfaces with theorem provers and model checkers, a simulator, and a code generator for real distributed code
Vortex Simulation of Turbulent Combustion( Book )

3 editions published between 1990 and 1992 in English and held by 1 WorldCat member library worldwide

This activity focused on the effect of density variation due to temperature/molecular weight difference and/or heat release in a reacting shear layer in two and three dimensional configurations. In the spatially growing 2D layer, results confirm mixing asymmetry due to density difference between the two streams. A light fast stream has a destabilization effect on the early stages of development; it promotes early roll-up; induces stronger winding inside the eddies, and initiates the pairing at earlier stages. However, the overall spatial growth rate of the layer increases as the density ratio becomes higher; bigger eddies are formed and pairing is completed faster. In 3D simulations, density difference continues to impart a convection velocity on the structures in the direction of heavy stream. That influences the evolution of the streamwise mixing modes and spanwise preferential entrainment is observed. 3D reacting shear layer simulations confirmed earlier 2D observations that although the reaction zone structure depends on the Damkohler number, product distribution is independent of the kinetic parameters and exhibit strong resemblance to the vorticity field.

Development of Novel Bifunctional Compounds That Induce Apoptosis in Prostate Cancer Cells( Book )

6 editions published between 2004 and 2009 in English and held by 1 WorldCat member library worldwide

We have designed and synthesized a novel compound (I ip) that efficiently triggers apoptosis in prostate cancer cells such as LNCaP. This bifunctional compound was designed to form DNA adducts that are camouflaged by the androgen receptor making them less readily repaired in AR+ prostate cancer cells. The aims of our studies are to investigate the mechanisms by which lip is able to trigger apoptosis in target cells. One approach we are taking is to prepare structural analogs of lip that have increased or decreased abilities to cause apoptosis in LNCaP cells. Methods have been developed that will permit us to determine the fates of lIP-DNA adducts in treated cells as well as in target and nontarget tissues in xenograft mouse models of human prostate cancer. Another objective is to identify the signaling events that lead from DNA adducts to activation of the apoptotic program. Finally we have obtained encouraging results from animal experiments that indicate that molecules such as lip may have clinical potential for the treatment of human tumors
Development and application of the mollusc Arctica islandica as a paleoceanographic tool for the North Atlantic Ocean by Christopher R Weidman( )

1 edition published in 1995 in English and held by 0 WorldCat member libraries worldwide

The 14C and 180 composition of the annually banded, carbonate shell of the long-lived (+100 years) mollusc Arctica islandica are shown to be practical for reconstructing long term, high-resolution, DIC 14C and bottom temperature time histories for the continental shelves of the northern North Atlantic Ocean. However, its I3C composition is shown not to be a good recorder of ambient DIC 13C, and likely is controlled by physiology. Four shell-derived 14C time histories are reconstructed for the high-latitude North Atlantic Ocean. These records show significant spatial and temporal differences in the evolution of surface 14C between subpolar and subtropical regions, which are attributed to regional differences in mixed-layer depth and the presence of deepwater sources. A shell-derived 109-year record (1875-1983) of bottom temperatures has been reconstructed for a location near the former Nantucket Lightship (400N, 690W). The detrended annual temperature anomalies of this record show significant positive correlation with regional bottom, sea surface and air temperature anomalies. However, the shell-derived record describes a century-long cooling (approx. 10C) in contrast to a century-long warming of regional sea surface temperatures of equal magnitude. This long term divergence between surface and bottom conditions is attributed to increased seasonal stratification
A Novel Monoallelically Expressed Candidate Tumor Suppressor Gene for Breast Carcinogenesis on Chromosome 11p.15.5( )

3 editions published between 2000 and 2002 in English and held by 0 WorldCat member libraries worldwide

I have identified a novel Xist-like nuclear transcript (11p-xlnt) which is monoallelically expressed and accumulates in the interphase nucleus at its site of transcription. 11p-xlnt is transcribed from within a narrowly defined 500 kb portion of human chromosome 11p15.5 that exhibits loss of heterozygosity (LOH) in 40% of breast cancers. I have shown that 11p-xlnt is transcribed from within an intron of and antisense to the KvLQT gene and spans at least 40 kb of genomic sequence. Construction and screening of a cDNA library failed to reveal evidence of splicing for this large transcript. While transcription appears to be exclusively from the paternal allele in normal tissues, I have shown that expression occurs from both maternal and paternal alleles in a rhabdomyosarcoma cell line, although expression is found to be monoallelic on a single cell basis by RNA FISH. 11p-xlnt may play a part in local and regional gene regulation at the imprinted domain on chromosome 11p
