This investigation was designed to compare the growth in attitudes
toward science and the critical thinking abilities of high
school juniors in chemistry to juniors not enrolled in chemistry.
One hundred and fifty-three chemistry students and 149 non-chemistry
students were randomly selected to participate in the study.
Criterion tests used...
The purpose of this study was to investigate the relationship between poverty and mental retardation and to place mental retardation in its true perspective as a social condition which thrives especially in poverty areas. More specifically, this study attempted to determine if there was any significant relationship between selected social...
The in vitro effects of cortisol in regulating salmonid B cell functions were
investigated. B cells at three distinct stages of differentiation were examined for
cortisol sensitivity. B lymphocyte responses were examined 1) during the early stage
of the precursor, 2) during the intermediate stage of differentiation associated with
clonal...
Studies were directed toward the formulation of a selective
Aeromonas medium that would permit the isolation of Aeromonas
species in the presence of other common bacterial flora. The final
composition of this medium, PBG Agar, in grams per liter, is:
Bacto-peptone, 10; Bacto-beef extract, 10; glycogen, 4; NaCl, 5;
sodium...
Our objectives were to determine 1) the concentration of prostaglandin
F2α (PGF2α) in whole and extended bovine semen, 2) if concentrations of
prostaglandins in extended bovine semen are correlated to fertility, and 3) if PGF2α
administered at the time of artificial insemination would improve conception rate.
Concentration of PGF2α tended...
The extensive reduction in adult Pacific lamprey (Entosphenus tridentatus) counts at many hydroelectric dams in the northwestern USA signals a substantial decline in lamprey numbers across the entire region in the past 40 to 50 years. Among the many potential causes of this decline, obstruction of migration routes has likely...
This thesis contains three manuscripts addressing the application of stochastic processes to the analysis and solution of partial differential equations (PDEs) in mathematical physics.
In the first manuscript, one dimensional diffusion and Burgers equation are considered. The Fourier transform of the solution to each PDE is represented as the expected...
The gauge integral is a rather obscure object in mathematics. Like the Riemann integral, it is relatively simple to define, but unlike the Riemann integral, the gauge integral has the ability to integrate a very large class of functions. Here, we provide a development of the gauge integral at an...
