The concentration of ascorbic acid in the plasma was determined on
four levels of ascorbic acid intake for seven day periods in 1946-47 and
on three levels of ascorbic acid intake for ten day periods in 1947-48.
The subjects, eight girls and eight boys, were 16 to 19 year old...
This investigation was concerned with the reduction of
waste in raw vegetables and fruits between the times of harvest
and consumption. Reduction of spoilage in produce was attempted
by means of chemical and. physical agents as well as a combination
of both.
The first phase of the work consisted of...
The blood thiamine concentration of 11 subjects was determined
by means of the Friedemann and Kmieciak (1943) method every 5 days
during a 30-day experimental period. Study I was conducted on 5
students in 1947 and Study II was conducted on 6 students in 1948.
The subjects in both studies...
The study reported in this thesis is part of an investigation designed to determine the metabolism of thiamine and riboflavin in human subjects who were maintained on controlled diets. Part of this investigation was made during a 30-day experimental period in 1950 and the other part, during a 30-day experimental...
Levels of ⁶⁵Zn in water, sediments, plants, and animals in
Alder Slough, a small ecosystem in the Columbia River Estuary,
were determined periodically during a one year period. Concentrations
of total Zn in organisms were also measured to permit
computation of specific activities (μCi⁶⁵Zn/g total Zn). Temporal
fluctuations in the...
A mathematical model was developed to predict the absorption
rate of a slightly soluble gas entrained by a plunging liquid jet. The
single parameter of the model, the transfer factor, TF, was defined
as the summation of the product of the mass transfer coefficient and
interfacial area over all the...
