Computer Analysis Of The Stefan Problem In Cryosurgery, Dong Hyuk Kim

Theses

Numerical solutions for determining the freezing front location vs time relation in cryosurgery are obtained by utilizing the heat transfer computer program TRUMP, which employs the explicit finite difference algorithm. The probe geometries of rectangular, cylindrical, and spherical shape with one dimensional heat flow are selected for study. Internal heat generation is considered in cylindrical and sphe¬rical probe geometries, and the difference between the solutions with and without heat generation is discussed. To verify the correctness of the TRUMP solution, comparisons are made in the freezing distance vs time relation with the Neumann's solution and the implicit enthalpy method for …

Reliability Studies On Solid Tantalum Electrolytic Capacitors, Hamed Nassar

Theses

The primary objective of this thesis is to determine and analyze the failure mechanisms of solid tantalum capacitors, pinpoint the causes, and suggest the precautionary measures that prevent the occurrence of these failures.

The experimental part of the study is a life test (1000 hours) of solid tantalum capacitors under humidity and high temperature. To avoid the misconception that could happen by investigating a particular manufacturer's product, units from …

Calibration Of Flame Ionization Detector For Chlorinated Hydrocarbons, Nahid Jabalameli

Theses

Relative Responses and Calibration Factors were developed for several volatile organic (mostly chlorinated) priority pollutant species in order to use one single stable compound (e.g.Benzene) for daily instrument calibration. This would replace the procedure of using a standard mixture of target compounds (25-35). This is of particular advantage because the standard mixture may not have all species stable or may show loss of some components relative to others due to wall adsorption in the standard (compressed gas) stainless steel cylinder.

The use of a single standard species was made possible by developing "accurate" relative response and calibration factors of all …

A Study Of Worker Motivation, Farid Uddin Ahmad

Theses

This thesis mainly deals with the motivation of the production managers, engineers, technicians and production workers. The purpose is to emphasize the need for providing due motivations to an important work group of the industry who are largely ignored. An attempt has been made to amply demonstrate the various techniques for worker motivation. As the study of standard motivational theories alone cannot solve the complex motivational problems, all possible efforts have been made to relate, integrate and blend the theories with actual applications in the organizations. All the relevant and important issues connected with worker motivation have been highlighted. Points …

It was decided to consider an apartment complex of approximately 200,000 ft² having peak heating and cooling loads of approximately 4.92 million Btu/hr and 2.93 million Btu/hr respectively for this analysis. The average electrical demand was 520 KW. Next …

Volatile Organic Pollutant Levels In Indoor Environments From The Use Of Kerosene Heaters, Kashinath Banerjee

Theses

The indoor air pollutant levels caused by use of kerosene stoves as sources of heat in residences is of increasing concern as the use of such heaters becomes more widespread. Emission of volatile organic. species (aliphatic hydrocarbons from hexane to dodecane, cyclohexane and aromatic species including benzene, toluene, ethyl benzene, m/p xylenes, o-xylene and styrene) from these devices were measured at different sites. The organic vapor samples have been collected by adsorption on Tenax GC, and quantitatively analyzed by thermal desorption into a high Resolution capillary column gas chromatograph. Mass spectral analysis was also conducted for qualitative identification of sample …

Acrylamide Effects On Nerve Terminal Enzymes, Christopher S. E. Marlowe

Theses

Acrylamide causes a peripehral neuropathy. The biochemical mechanism by which it does so is the subject of intense investigation. One of the principal hypotheses for this mechanism centers on acrylamide's ability to inhibit glycolysis. This study examines the effects of in vivo exposure to acrylamide on the enzymes of the nerve terminal particle, the synaptosome.

A method for measuring glycolytic enzyme inhibition in the synaptosome was developed. Acrylamide (500 mg/kg) was administered to rats intraperitoneally. Synaptosomes were prepared by the method of Dodd et al, and lysed by sonication. GAPDH activity and NSE concentration were measured. GAPDH inhibition measured in …

Prediction Of Pore Water Pressure During Earthquakes In Southern Kyoto Area, F. Oka

International Conference on Case Histories in Geotechnical Engineering

This paper is concerned with the liquefaction analysis for the hypothetical earthquake in southern Kyoto area in Japan. The method of liquefaction analysis can consider the local soil properties of sand and clay, using the constitutive equations of clay and sand, and the theory of mixture. From this study, it becomes evident that liquefaction will occur at the site near the river, and also liquefaction can be observed in the clay layers.
