There is an increasing need for development of laboratory
identification procedures for purposes of plant variety protection, seed certification, quality control and consumer protection. In the past there were fewer commercial varieties and field
testing methods based on morphological differences were used satisfactorily. These tests require several months to complete...
One hundred and fourty-one lambs showing signs of pneumonia
and/or enteritis from four different flocks in western Oregon were
sampled for virus isolation. Two ovine adenoviruses, antigenically
distinct from each other and from bovine adenoviruses, were
isolated from the nasal mucosa and feces of two lambs. The lambs
were showing...
Pacific shrimp (Pandalus jordani) was washed repeatedly and the
eluted bacteria were enumerated and identified. Selected isolates
were tested for their adhesive properties.
Washing reduced the microbial load by 3.84 to 42.04%. The bacteria
which most resisted wash-off were Staphylococcus and Pseudomonas
spp. The easiest to wash off was Flavobacterium...
This is a psycho-socio-linguistic study of language
as the primary tool of institutions such as education,
government, and religion. These institutions have goals
associated with identifying with, communicating with, and
influencing individuals in the general public who are not
Part of the group. A review of psycho-socio-linguistic
theory suggests that...
Previous studies have shown loss of ethofumesate activity when
the herbicide was applied to dry soil (2% w/w moisture content) in
both field and greenhouse studies, even when rainfall or irrigation
was received within a few days. Laboratory studies were conducted to
determine the mechanism for this activity loss. Dry...
Diet, nutrition, and foraging strategies of canvasbacks (Aythya valisineria) and redheads (A. americana) were studied by collecting actively feeding birds throughout the reproductive season in 1980 and 1981; samples of available foods were taken each time a bird was collected. Nutrient composition of the aggregate diet was determined for each...
Various hypervalent iodine compounds were evaluated as reagents
for intramolecular phenolic oxidative coupling. It was found that
phenyliodine(III) bis(trifluoroacetate) was effective for the coupling
of the monophenolic substrate 13a to 14a under neutral conditions.
Vanadium oxytrifluoride and hypervalent iodine compounds were compared
as oxidants for the conversion of 32 to...
