Indole-3-carbinol (I3C) and butylated hydroxyanisole (BHA), anti-carcinogens
present in the human diet, were tested for their in vivo
and in vitro effect on aflatoxin B₁. (AFB₁) metabolism, and DNA adduct
formation in the rainbow trout. Dietary BHA at either 0.3 or 0.03%
had no effect on the hepatic tumor incidence...
This study employed ethnographic methodology to investigate and record the post-camp, pre-assimilation period of Laotian refugees.The primary goal was to document the special problems and experiences of the Laotian population as they attempted to adjust to new roles and expectations within mainstream North American society.Oral histories and biographical statements focused...
Most flexible manufacturing systems (FMS) presently in use have generated only modest productivity increases in proportion to capital in vested in the process, or they have not been favorably reviewed when compared to the investment costs of other improved manufacturing systems. This thesis presents a simulator program which will assist...
This thesis presents my research on the hardware and software for
control of a novel robot based on the Stewart Platform. The robot has
six actuators which must be adjusted to arrive at the desired position
of the platform. This position must be specified by six position
parameters; namely the...
A program has been written to investigate the
dynamics of robot manipulators during task execution.
The program simulates robot motion along a path specified
by the user. A smooth trajectory is generated by
interpolation in joint space. Forces and torques on
actuators are calculated at intermediate points, using a
recursive...
Expert systems have been suggested as a solution
for difficult problems, including FMS scheduling. As
one of the aspects of artificial intelligence (AI), expert
systems have achieved considerable success in recent
years in medical science, chemistry, and engineering.
However, building an expert system is a difficult
task, the most crucial...
The purpose of this study was (a) to develop a valid and reliable attitude
toward science instrument for use with Arabic male students at the secondary
school level, (b) to determine the differences in their attitudes toward science and
in their achievement, and (c) to determine the relationship between measures...
To investigate the responses of healthy adult women to two
levels of vitamin B-6, a seven week two-part experiment was conducted
with five young adults and eight middle-aged subjects. During the
four unsupplemented weeks, dietary vitamin B-6 was 2.3-2.4 mg/day.
In the final three weeks, the same diet was supplemented...
