Non-Equilibrium Parametric Pumps For Separating Liquids Or Gases, Anil Krishna Rastogi

Theses

An experimental and theoretical study has been done of Non-Equilibrium parametric pumps. Mathematical models and computer programmes are developed for both thermal and heatless parametric pumps based on non-equilibrium conditions and linear isotherms. A mathematical study was done for thermal parametric pumps whereas both experimental and theoretical studies were made for a heatless parametric pump. The effect of different operating conditions has been investigated on the separation of NaCl-H₂O via a thermal parametric pump and He-CO₂ and He-C₃H₆ gas mixtures via a heatless parametric pump.

The experimental study of heatless parametric pumps was extended …

Air Control In A Newark City Subway Station, Robert H. Burch

Theses

During the period from June, 1974 to January, 1976, 103 24-hr samples of the air at the Broad Street station of the Newark City Subway were collected by cascade impactor. The size distributions (based on Stoke's equivalent diameters) of the total suspended particulate matter were determined gravimetrically. Samples were also analyzed by atomic absorption spectrometry to obtain information on the concentration of iron, manganese, lead, copper, zinc, and cadmium in each size fraction. The geometric mean particulate level was found to be more than twice the Federal Ambient Air Quality Standard and triple that of ambient Newark air sampled nearby. …

An Approach To Energy Conservation In A Manufacturing Industry, William Polignano

Theses

The approach attacks the problem of control and planning of energy usage via three major categories. These areas are: detection, forecasting and reporting of energy usage.

To initiate any energy program the first step, is the identification of the areas that use the most energy, thus allowing detailed studies to be concentrated in these energy-intensive areas. The author has attempted to show which areas are energy-intensive in his employer's plants.

The second step is the accurate forecasting of energy usage. The author has attempted this via an econometric forecasting model that accurately predicts energy usage based on direct labor hours …

Point Of Operation Safeguarding - A Metal Forming System Approach, William Baker Eaton

Theses

The mechanical power press in its application in the metal stamping and forming industry has been misinterpreted as a selfcontained metal forming system. Examination of the production routines involving the press show that this machine is actually only one elemental component of the metal forming system and not the total production unit.

Authoritative codes and standards pertinent to the mechanical power press have reflected this misinterpretation by not including system considerations in their contents. These omissions have resulted in the providing of safeguards which do not properly reflect the particular characteristics of the metal forming system to which they are …

Thermal Decomposition Products Of Kynol And Nomex With Reference To Structure And Toxicity, Shaker H. El-Sherbini

Theses

The purpose of this investigation was to study the combustion products of KYNOL and NOMEX as a fire retardant fibers. From the quantitative analysis data of the combustion products, the polymer structure is discussed and the property of thermal stability is explained.

From the analysis of the combustion products, the toxicity indices for the two fibers are determined. It is found to be 0.1 for KYNOL and 0.71 for NOMEX. This can be interpreted to mean that, if one gram of MIDI, is decomposed and the combustion products were diffused in one cubic meter of air, the probability of dying …

Image Intensification By Superimposed Vesicular Images Generated By Decomposition Of Hydrogen Peroxide, William Grabenstetter

Theses

In the late 1960's, Weyde discovered that treating conventionally processed silver halide films with hydrogen peroxide led to intensified densities by the superimposition of vesicles at the silver image sites. This project attempted to reproduce the results of 5° - 10°DIN speed increase and excellent sharpness mentioned in the patents issued to Weyde. Using the patents as a reference, a paste of urea hydrogen peroxide and PEG was examined as an image intensifier, with no success. Alternate binders suggested in the patents were then examined, Triton X-405 proving to be the best. A paste of 4g. urea hydrogen peroxide in …

Copper Physical Development Of Copper Latent Images, Gregg Tashker, Peter Schreiber

Theses

Copper physical development of copper latent images was researched. The proposed method for producing copper latent images was to soak a titanium dioxide in a copper (II) sulfate nucleating bath and expose to UV radiation below 4l0nm. The exposures were to produce the copper latent image. Three physical developers were used to try to intensify the latent images. The developers utilize an iron (II)/iron (III) redox system to reduce copper (II) sulfate to copper metal. The developers also contain carboxylic acids as complexing agents for iron (III) ions and cationic surfactants for stability. The printout achieved was not stable and …

Mtf And Adjacency Effects Of Vesicular Film, Timothy Sewell, Paul Willig

Theses

The Modulation Transfer Function and adjacency effects are important measurements of a photographic material. For vesicular film it is of interest to investigate the MTF and adjacency effects with relation to the three variable parameters, development temperature, exposure and development time. This investigation clearly shows that adjacency effects do occur in vesicular film, and that exposure and development temperature are important factors in determinating the film MTF.

A Study Of The Effect On Direct Stencil Edge Definition Of Emulsion Thickness, Screen Mesh Count, Fabric Thread Thickness And Coater Blade Thickness, George Bedirian

Theses

The present study arose out of a desire to test the assumption that in order to obtain direct stencils with good edge definition, one either had to use fine screens or. If using a relatively coarse screen, apply multiple coatings of emulsion to the screen before making the stencil. Neither alternative seemed satisfactory, since the first did not allow optimal use of the scope of screens available, and the second entailed an expenditure of time and supplies that could possibly be shown to be unnecessary. It was therefore determined to carry on an experiment that would show whether direct stencils …

A Static Stress Analysis Of The Glass Metal Truss-Type Column Of The Van De Graaff Accelerator, Rudolf Prechter

Theses

A static stress analysis of the glass-metal truss type bridge of a Van de Graaff Accelerator is presented. The solutions are first computed using conventional methods such as method of joints and the method of virtual work. Secondly, the solutions are found using a computer program, SAP IV, which is a structural analysis program for static and dynamic response of linear systems. The solutions are then compared to each other and appropriate conclusions are presented.

Bioenergy And Emotions, Vickie C. Walter

Theses

This thesis explores the concept of bioenergy as an integral force underlying both human physiology and emotional experience. Drawing on a wide range of historical, cultural, and scientific perspectives, the work examines how different traditions and researchers have conceptualized and attempted to measure or influence this subtle energy. The discussion begins with Wilhelm Reich’s notion of “orgone energy,” a vital force he linked to psychological health and emotional regulation. Reich’s controversial theories and experimental devices are considered in the broader context of psychoanalysis and somatic therapy.

The study then traces parallels between Reich’s work and ancient energy systems such as …

Feasibility Of Meeting Student Health Needs Through A University Health Center Based Hmo, Ronald Duwayne Reed

Theses

The thesis, "Feasibility of Meeting Student Health Needs Through a University Health Center-Based HMO" by Ronald DuWayne Reed, explores the potential of implementing a Health Maintenance Organization (HMO) model at the University Health Center (UHC) on the College Park Campus of the University of Maryland. The study aims to address the challenge of maintaining comprehensive health services for students amid declining state funding.

Reed examines the UHC's existing services, including primary care, women's health, mental health, health education, and environmental health, highlighting areas where improvements are needed. The analysis evaluates the UHC's ability to provide primary care, manage patient loads, …
