The Quantitative Analysis Of Airborne Particulates By X-Ray Flourescence, George C. Asteriou

Theses

Airborne particulate matter from the New Jersey State area collected on Quartz Microfiber filters was analyzed by X-Ray Fluorescence spectroscopy. The quantitative analysis of the samples against N. B. S. standards produced results which were compared with Atomic Absorption analysis

The results from the two methods were correlated by the introduction of empirical factors for each element.

However, a larger number of analyzed standards of varied composition, along with the creation of a spectral library, can minimize the need for empirical factors and yield accu¬rate results.

The Kinetics And Hepatotoxicity Of Benzyl Chloride Vapor In Rats, Hari V. Rao

Theses

Male Sprague Dawley rats (250g) were exposed to benzyl chloride vapor at a concentration of 220 ppm for 6 hours. During inhalation, the blood benzyl chloride concentration increased to reach a steady state level of 9-10 ug/ml between 4 and 6 hours of exposure. A small concentration of benzyl chloride (0.86 ug/ml) was present in the blood four hours after the termination of exposure. The absorption half life was 0.53 hours (0.39-0.81) and the elimination half life was l.12 hour (0.93-l.40).

The absorbed benzyl chloride was largely retained in the blood and some of it (0.22 ug/g) was sequestered into …

Human Factors In The Design Of Computer Graphics Input/Output Interfaces, Michael Uche Amadi

Theses

Computers are used for solving problems of various kinds and therefore, if the users are to fully benefit from the systems, they must be considered during the earliest stages of the system development. There are three major classes of computer users namely: naive, managerial, and scientific-technical. These users have different characteristics that the designer must consider within his/her system. Only by including such distinctions will these user groups each be able to perform at their respective optimum levels. Just as there are different users, there are also numerous applications to which computers can be applied. This thesis will be restricted …

Theses

A data acquisition and analysis stem for use in the study of laryngeal dynamics has been built and tested. The special feature of the system is the computer controlled digitizing rate and coordinated subject pitch prompting. Tokens of steady state laryngeal vibration are obtained from an electroglottograph when the subject intones a series of computer prompted pitchs in a musically scalar sequence. The digital samples of this data are captured by the system at a basic rate of 200 samples per laryngeal cycle. This procedure enables the system to perform a modal analysis of laryngeal function, not unlike the analysis …

Pressure Distributions In Microvascular Network, David Moshenberg

Theses

The objective of this study was to find a practical way of estimating the pressure distribution in a network of microvascular vessels. The pressure distribution was evaluated twice, namely before vasodilations or vasoconstrictions and after the network of vessels reached a new steady state with respect to pressure and flow. Along with determining the pressure distribtuion, the simulation also calculated an effective blood viscosity coefficient for the network.

Poiseuille's equation and the axial component of the equation of motion were used to evaluate the steady state pressure and velocity distributions in each vessel. The continuity equation (conservation of mass) was …

The Effects Of Early School Entrance On Standardized Test Performance, Janet Prior

Theses

This study was designed to investigate whether early school entrance affected the level of standardized test performance as a child progressed through school.

It was hypothesized that students' standardized test scores would correlate significantly with the age at which they entered school, that the standardized test scores of early-entrants would be significantly lower than middle-entrants and late-entrants, that standardized test scores of middle-entrants would be significantly lower than those of late-entrants, and that there would be a significant difference between the standardized test scores of girls and boys whose chronological ages were similar at the time they began attending school. …

Keeping Up With Technological Change, Karlis V. Kopans

Theses

Advances in technology over the past fifty (50) years have changed virtually everything that touches our lives today to some degree. However, in the last five years or so, these innovations have been combined into products and systems which have visibly begun to change society as we have known it in the past.

Only in recent years, have the affects of technological change or innovation on society begun to be examined. While a fair amount of literature has been published to date on specific areas of technological change, few publications have been produced which provide a general overview of the …

Reflection Upon The Intangible Process Of Professional Development In A Graduate Program In Counseling Psychology, Judy Iris Fletcher, Mary Randa Kapp

Theses

The following narrative is a personal account of the experiences, observations, and awarenesses of two students completing their Masters degrees in counseling psychology. It represents an effort to document what we view as an identifiable and stress-producing process of growth occurring within an academic framework. We feel that this duality of personal growth and professional development is inadequately addressed in graduate programs. Yet, we have found this unstated, underlying, and inevitable threat of uncertainty, risk, and change to be as predictable a reality as the theoretical coursework required.

This paper is written not so much to prove a point as …
