Computerized Analysis of Radiograph Images of Embedded Objects as Applied to Bone Location and Mineral Content Measurement

Description: This investigation dealt with locating and measuring x-ray absorption of radiographic images. The methods developed provide a fast, accurate, minicomputer control, for analysis of embedded objects. A PDP/8 computer system was interfaced with a Joyce Loebl 3CS Microdensitometer and a Leeds & Northrup Recorder. Proposed algorithms for bone location and data smoothing work on a twelve-bit minicomputer. Designs of a software control program and operational procedure are presented. The filter made w… more

The Hypothermic Perfusion of the Isolated Thyroid Gland and Its Release of T₃ And T₄

Description: Investigations have shown that the hypothalamus and pituitary respond to decreases in body temperature by stimulating thyroid release of T_3 and T_4 . This study was designed to bypass the control of the hypothalamus and pituitary gland and investigate the direct effect of temperature on the thyroid gland. Hypothermia was by an in vivo isolated perfusion of the thyroid gland. Radio-immunoassay was used to measure T_3 and T_4 concentrations. Significant increases were observed in animals perfuse… more

Thailand's Foreign Relations in Perspective

Description: The purpose of this thesis is to study Thailand's foreign relations. The specific argument will be that, to a large extent, Thailand was able to keep her independence because of her rulers' ability to adapt the country's policy to the changing circumstances in foreign affairs. Therefore, it was imperative for policymakers to look at the threats to the country's security from the local point of view and to develop appropriate policies for dealing with them accordingly. The thesis is organized i… more

Treatment of Migraine Headache Utilizing Cerebral Electrostimulation

Description: Cerebral electrostimulation (CES) as a treatment for migraine headache was investigated. Eighteen participants recorded data on headaches for two baseline weeks. Six were assigned to each of three groups--an active treatment group receiving CES, a placebo group receiving a simulated version of CES, and a no-treatment control group placed on a waiting list during the study. The CES group evidenced a significant reduction in headache duration and intensity relative to the placebo group. The waiti… more

Regulation of Pyridine Nucleotide Metabolism in Saccharomyces cerevisiae

Description: The levels of total nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), and their redox states were determined as the function of growth in S. cerevisiae. Cells growing in a medium containing 0.8% glucose exhibit two phases of exponential growth, utilizing glucose and ethanol, respectively. The NAD pool is 50% reduced during both stages of growth while the NADP pool is 67% reduced in glucose growth and 48% reduced in ethanol growth. The NAD/NADP ratio… more

Analysis and Comparison of a Developmental Task Scale on Differing Adolescent Populations

Description: The following research questions were investigated: (a) Can the age-mates scales from the Dales developmental task scales be used with southwestern-urban adolescent populations? (b) Are there any systematic differences between northeastern-nonurban and southwestern-urban subject populations on the response to these scales? The subjects consisted of 884 adolescents, 11 through 15 years, evenly divided by sex. Subject responses were analyzed by sex and age groups using Guttman scalogram analysis.… more

Life Stress and Industrial Accidents

Description: Traditional personality research on accident behavior has produced conflicting opinions as to the traits that describe the "accident-prone" personality type. Other research has shown that psychosocial life stress, while partially determining the temporal onset of a variety of illnesses, may also be a factor contributing to increased accident liability. This study examined the role of temporary and stress-producing life changes in groups of accident-free and accident-involved industrial employee… more

A Comparison of the Moral Judgements of Males and Females as a Function of Merging Sex Roles

Description: Factors which influence severity of moral judgement in men and women were investigated in this study with 94 male and 89 female undergraduate students as participants. Effects of "sex of judge," "sex of transgressor," and "value orientation" variables were examined across five diverse story conditions. A measure of identification was also obtained. As hypothesized, a significant main effect was found for "value orientation," but not for "sex of judge" or "sex of transgressor" variables. The hyp… more

A Self-Control Approach to Weight Control

Description: A strategy for facilitating post-treatment weight maintenance was examined. Subjects were matched for age, sex, and amount of weight that they desired to lose and were then assigned to one of two groups. Both groups were under contracts and had individually designed self-control programs for weight loss, but subjects in the experimental group lost weight in small steps and subjects in the control group lost weight continuously. The experimental group was predicted to have better weight maintena… more

Symbolic Language Transfer in the Autistic Child

Description: The problem of this study is to see if there is more symbolic language transfer by autistic children in an untrained matching situation if there has been previous training on similar matching situations. The purposes of the study are twofold. The first is to see if subjects will make a motor sign response untrained to an object if the word for the object has been trained to the motor sign response and to see if they will make a motor sign response untrained to a word for an object if they have … more

Population Genetics, Karyology, and Morphology of Certain Species of the Peromyscus Truei Group

Description: The systematic relationship of two species of the Peromyscus truei group (P. truei and P. difficilis) was analysed through the application of starch gel electrophoresis, numerical taxonomy, and chromosomal techiques. Of 20 loci examined, 11 were monomorphic in all populations, two exhibited variation in only two populations, and seven loci were polymorphic in two or more populations. The mean number of polymorphic loci per population was 0.186, the mean number of polymorphic loci per individual… more

Spectroscopic Investigation of Some Allyl Alkali Metal Compounds

Description: To gain better understanding of the nature of the carbonmetal bonding in 3-neopentylallyl alkali metal (5,5-dimethyl- 2-hexenyl alkali metal) systems, an investigation is extended to 3-neopentylallylpotassium. In addition, pertinent data on the 3-neopentylallyl systems are re-examined in an attempt to understand the trends in the bonding habits, as affected by the solvent, the cation and the temperature.

An English and Arabic Character Printer

Description: This paper is presented in satisfaction of the requirement for two problems in lieu of thesis which are required for the degree, Master of Science. The two problems are: (1) to provide an electric interface between the M6800 microprocessor and the printer; and (2) to design an Arabic character set and to provide the logic required for its implementation. As it would be artificial and impractical to document these problems separately, a single document here is provided.

Studies of design parameters in the fabrication of Nb--Al--Ge superconductors by the powder metallurgy infiltration method

Description: Experimental studies have been carried out in which the A15 phase of the Nb-Al-Ge system has been synthesized in the form of thin filaments contained in form rolled wires. A powder metallurgy approach has been used to achieve controlled porosity in compacts of sintered niobium powder. Infiltration with an aluminum-germanium eutectic alloy followed by mechanical deformation has produced small interconnected filaments embedded in the Nb matrix. Diffusion heat treatment for a short time transforms… more
