A morphological study of the avian (Gallus domesticus) ductus arteriosi during hatching.

Description: The ductus arteriosi (DA) are two blood vessels connecting the pulmonary arteries to the descending aorta in the avian embryo. Following hatching, the DA closes, separation of the systemic and pulmonary circulation. I present the morphological changes that occur in the chicken DA during prepipping, internal pipping, external pipping, and hatching. The avian DA consists of two distinct tissue types, a proximal and a distal portion. Histological examination shows developmental differences bet… more

VO2 response profile in heavy intensity cycling after heavy intensity arm or leg exercise.

Description: The elevated CO2 levels, elevated temperature, and lower blood pH that may occur during exercise should enhance O2 delivery to the exercising muscles. It was hypothesized that performance of prior exercise (PE) would result in a faster VO2 response, as well as a reduced slow component contribution, in subsequent exercise bouts. Five women (21 ± 1 yr) and 10 men (23 ± 2 yr) performed nine 6-min bouts of heavy intensity cycle ergometer exercise (i.e., above the ventilatory threshold, individual… more

Supercritical Silylation and Stability of Silyl Groups

Description: Methylsilsesquioxane (MSQ) and organosilicate glass (OSG) are the materials under this study because they exhibit the dielectric constant values necessary for future IC technology requirements. Obtaining a low-k dielectric value is critical for the IC industry in order to cope time delay and cross talking issues. These materials exhibit attractive dielectric value, but there are problems replacing conventional SiO2, because of their chemical, mechanical and electrical instability after plasma p… more

Effect of Biofeedback-Assisted Relaxation Therapy on the Psychophysiological Measures of Stressed-Out Working Professional Mothers

Description: This study was designed to determine the effectiveness of biofeedback-assisted relaxation therapy on reducing psychophysiological stress levels of working professional mothers. Participants were 14 working professional mothers from a major daily newspaper. Reported stress levels were measured with the 123 question Stress Profile (Nowack, 1990) three times during the eight week treatment study that was held at the women's workplace. A repeated measure ANOVA design was used to analyze the data an… more

Mathematical Modeling of Charged Liquid Droplets: Numerical Simulation and Stability Analysis

Description: The goal of this thesis is to study of the evolution of 3D electrically charged liquid droplets of fluid evolving under the influence of surface tension and electrostatic forces. In the first part of the thesis, an appropriate mathematical model of the problem is introduced and the linear stability analysis is developed by perturbing a sphere with spherical harmonics. In the second part, the numerical solution of the problem is described with the use of the boundary elements method (BEM) on a… more

Automated Low-cost Instrument for Measuring Total Column Ozone

Description: Networks of ground-based and satellite borne instruments to measure ultraviolet (UV) sunlight and total column ozone have greatly contributed to an understanding of increased amounts of UV reaching the surface of the Earth caused by stratospheric ozone depletion. Increased UV radiation has important potential effects on human health, and agricultural and ecological systems. Observations from these networks make it possible to monitor total ozone decreases and to predict ozone recovery trends … more

Influence of executive function on medication adherence in neurologically impaired and non-impaired elderly.

Description: Medication non-compliance has become one of the most prevalent reasons for hospitalization and doctor's visits by the elderly. As the elderly population is more likely to have decreased cognitive abilities, it is suggested that neuropsychological factors, especially executive function, are more influential in medication non-compliance than once thought. This study looked at executive function performance on a traditional battery of neuropsychological tests, self-report of perceived ability to p… more
