In 1906, applying Charles Darwin's evolutionary theories to the human race, Sir Francis Galton introduced the concept of eugenics, "the science of the improvement of the human race by better breeding." The rediscovery in 1900 of Mendel's laws of genetic inheritance and an upsurge in hereditarian thought set the stage...
The purpose of this study was to determine the effect of a
labyrinthine dysfunction, with and without visual cues, on underwater
submergence. The subjects utilized were fifteen bilateral
neural deaf males, nine conductive deaf males and sixteen hearing
males. Following a series of pre-tests, administered to determine
balancing difficulties, each...
This dissertation uses a new methodological approach for an in-depth analysis of three cartographic works. Studies within the discipline of the history of cartography have followed various methodologies throughout the past century. This dissertation argues that in order to come to a more complete understanding of how maps were produced...
The bioavailability of vitamin B₆ in four selected foods
(bananas, filberts, soybeans and beef) was determined in five men,
aged 22 to 25 years, who were saturated with pyridoxine. The study
consisted of a five-day adjustment period followed by a 28-day experimental
period. All subjects consumed a constant diet containing...
The influence of riboflavin doses on the urinary excretion of
riboflavin and 4-pyridoxic acid was investigated in 6 young men.
Doses of crystalline riboflavin and/or pyridoxine were administered
on days 10 to 25 using a 6 X 6 Latin square design. The 6
crystalline vitamin doses given were: 0.3 mg...
The effect of pyridoxine (PN) supplementation on lymphocyte
responsiveness was investigated in 15 elderly volunteers (aged
65-81 years) by measuring lymphocyte proliferation to T and B cell
mitogens, lymphocyte subpopulations with monoclonal antibodies
(T3, T4, T8) and plasma pyridoxal 5'-phosphate (PLP) concentration
at pre-supplementation and after 1 and 2 months...
This study investigated the effect of first aid instruction on
college students' attitudes toward safety. It evolved from previous
studies of the relationship between first aid and accidents in Canada
and the United Kingdom. These earlier studies were concerned with the
effect of first aid training on accident rates. The...
The leaching of water soluble phenolic compounds from
cold stressed Rhododendron leaves was found to be a reliable
indicator of tissue damage. In sublethally stressed leaf
tissues, more and novel phenolic compounds appeared and were
hypothesized to be precursors of cell wall components such
as lignin and suberin. Subsequent radiolabeling...
