An attempt to determine the relationship between the computer,
the computer program exchange organization and today's practicing
civil engineer has just been completed. A questionnaire was used to
obtain information and opinions from 850 selected practicing civil
engineers. Based on those questionnaires reaching their addresses,
a return rate of 81.7...
Abundant conidial production occurs from colonized straws and
plants infected with Cercosporella herpotrichoides Fron during the
cool moist months of the growing season. Experiments were
designed to study the survival, inoculum potential and competitive
saprophytic ability of conidia in soil.
Laboratory results indicated that cool moist soil favors the
saprophytic...
Project work of 4-H club members has been traditionally evaluated by a judge who awarded it a ribbon which denoted the project's quality. In Oregon several counties have tried a judge-member discussion period during which the judge and club member together evaluate the member's project in an attempt to improve...
Three trials with wethers and four trials with steers were
conducted to determine some of the effects of sodium bicarbonate,
calcium hydroxide and/or transfer of ruminal contents on ruminant
adjustment to abrupt changes to concentrate rations.
Lambs fed a basal concentrate diet plus sodium bicarbonate had
the highest average feed...
This report covers somewhat more than a full year of operation.
Individual contracts between the AEC and Oregon State University covering
the research of William Pearcy, Andrew Carey, Jr. , and Charles Osterberg
were combined into a joint contract on 1 November 1964. No Progress

Single-strain cultures of Streptococcus cremoris, Streptococcus
lactis, Streptococcus diacetilactis, and Leuconostoc citrovorum produced
little or no acetone and no dimethyl sulfide when grown in milk
culture. These organisms had little or no ability to decarboxylate
antexogenous source of acetoacetic acid nor were they capable of
producing dimethyl sulfide from methyl...
The unique reaction between 4, 6-dimethoxy-5-nitropyrimidine
and methylhydrazine was investigated. The reaction product was
identified as 4-hydrazino-6-hydroxypyrimidine from (a) spectral
data, (b) by direct synthesis of the product via 4-chloro-6-hydroxypyrimidine
and hydrazine, and (c) by conversion of the product to
the known 4-amino-6-hydroxypyrimidine using Raney nickel. The
product was not...
The initial purpose of this study was to develop a reliable method
for the determination of vitamin B₆ in blood. At the present time
microbiological assays have demonstrated greater sensitivity and
specificity than other methods for the of vitamin B₆ in
pure solution and many foodstuffs. However, adetermination pplication of...
Exploration of job opportunities and student involvement in learning are important principles of education. Congress recognized and emphasized these principles through recent legislation expanding education in several fields. Expanded vocational education has especially stressed job exploration and involvement in work programs. In many cases, however, this has come too late...
Submicron particulate (mean size of 0.52 microns) was filtered
from air at substantially atmospheric temperature and pressure by
passing air up through a bed of fluidized glass shot in a two inch column.
Removal efficiency, defined as the percentage removal of
particulate from the air stream, was essentially constant during...
