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...
A study has been made of the interrelations between certain of the physical and biochemical changes in three varieties of pears during storage and ripening. The metabolic changes which occurred in the fruit during cold temperature storage were found to influence with development of certain characteristics associated with dessert quality...
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...
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 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...
The purpose of this study is to bring together some data
relating to the general structure of the Portland livestock and meat
trade and to describe some phases of the functional process of concentration
and dispersion in physical terms as well as treat with some
factors significant to the marketing...
