The influence of ionizing radiation, photoperiod, and environmental temperature on cell proliferation in the intestinal epithelium of the rough-skinned newt (Taricha granulosa)

Creator:: Filipy, R. E.
Abstract:: Kinetics of cell division in the intestinal epithelial proliferative cells (cell nests) of the rough-skinned newt, Taricha granulosa, were studied using tritiated thymidine autoradiography and the mitotic arresting properties of colcemid. Percent labeled mitoses (PLM) curves were drawn from the autoradiographic data from two separate experiments in which the newts...

Circuit characterization for efficient computer analysis

Creator:: Magnuson, Waldo George
Abstract:: Analysis, coupled with an experimental investigation, is an important step in the design process of electronic circuits. Fortunately, with the development of computer programs to perform general network analysis, the job of analyzing relatively complex networks is not as formidable as it once was. This investigation develops guidelines for efficiently...

Determination of sub-nanogram quantities of boron by diffusion in silicon

Creator:: Khanna, Satya Pal
Abstract:: A technique was investigated in which a silicon crystal was used as a very sensitive detector of sub-nanogram quantities of boron. The unknown quantity of boron was spread uniformly on the surface of an n-type silicon wafer which was then baked for diffusion. The measured depth of the p-n junction...

Thin-film wideband tunnel-diode amplifier

Creator:: Hsieh, Edmund Jui-ching
Abstract:: Wideband tunnel-diode amplifiers using common-base transistor stages for isolation were investigated for stability criteria, frequency response, and the effects of temperature and voltage supply fluctuations. For the first time the full frequency spectrum of a tunnel-diode, from d-c to the gigahertz (GHz) range, was able to be utilized in an...

Properties of flash-evaporated gallium arsenide and gallium phosphide epitaxial films

Creator:: Matsuo, Samuel Seiji
Abstract:: The properties of flash- evaporated films of GaAs and GaP were studied in this investigation. Films were grown at various substrate temperatures, source temperatures, source-to-substrate distances and rates of deposition and were evaluated as to their structural, optical and electric properties. It was found that substrate temperature was the major...

Vacuum evaporated dielectrics in MOS structures

Creator:: Delzer, Dennis Richard
Abstract:: Vacuum evaporated dielectrics for use in MOS structures were studied in this research project. Dielectric films were deposited on substrates by electron bombardment evaporation of sapphire and quartz source materials. These deposited films were studied using infrared spectroscopy, index of refraction, density, and dielectric constant measurements. Etching tests were also...

Space-charge-limited currents in silicon using gold contacts

Creator:: Ede, Alan Winthrop
Abstract:: The theoretical characteristics of space-charge-limited currents in solids are reviewed, and a survey of suitable dielectric materials and experimental space-charge-limited devices is presented. The properties of the gold-silicon contact as used in space-charge-limited devices were experimentally investigated. It was found that the observed characteristics could be explained on the basis...

A MOS-transistor with submicron, and graded channel

Creator:: Chou, Pen Chao
Abstract:: The theoretical aspects and fabrication techniques of a new surface field-effect transistor were investigated. The new MOS-transistor uses a three-layer structure similar to those found in bipolar transistors. The new MOS structure introduces an impurity gradient in the channel region of the transistor and also makes it possible to reduce...
