The toxicity of chlorobenzene (CB) was investigated in rainbow
trout following acute ip administration (1. 0 ml/kg, 1:1 in corn oil)
and chronic exposure (2. 1 ppm and 2. 9 ppm) via the water in a continuously
flowing system for 15 and 30 days.
In the acute study, overt toxicity...
There was a linear relationship of [alpha]-amylase activity
from 2 to 12 hours incubation in both freeze-dried and fresh
'd'Anjou' pear fruit tissue. Activity was greater, however,
in fresh as compared with freeze-dried tissues. [alpha]-Amylase
activity from both types of samples was not detected until
60 minutes incubation. After 90...
Studies were conducted in 1976 and 1977 on the effects of harvest
dates on maturity, yields and sugar content of four cultivars of
sweet corn. The cultivars were 'Golden Cross Bantam', 'Jubilee',
'Rapidpak' and 'Tendertreat'. Moisture content of kernels ranged from
80 to 67 per cent for the six harvest...
In site index studies, the hypothesis that height
growth of most conifers is independent of stand density
is commonly accepted. However, some studies have shown
height growth to be influenced by density particularly
on medium to poor sites.
In this study two locations representing a high
quality site (Hoskins area,...
The validation and potential use of mathematical models to estimate the
shelf-life of refrigerated food exposed to temperature abuse and basing such
estimations on microbial growth was analyzed. Combined heat transfer, microbial
growth models, and non-parametric statistical procedures formed a computer-based
predictive tool to assess shelf-life and estimate the accuracy...
An outbreak of western spruce budworm Choristoneura
occidentalis in the Blue Mountains of eastern Oregon in
1983 was treated with helicopter applied carbaryl. Effects
of the spraying on forest ants were determined from pre- and
postspray samples taken from two carbaryl sprayed and
two unsprayed plots. In each 0.75-ha plot,...
To remain competitive in the international marketplace,
soft white wheat cultivars grown in the Pacific Northwest
must have consistent and predictable flour properties
including kernel texture. As a consequence, there is a need
to develop wheat cultivars for specific end uses. Wheat
cultivars with very soft kernels are used largely...
In the thinning theory, the hypothesis that the stand
growth is unaffected by the density over a broad range of
densities is generally accepted today.
In this study three different measures of stand density
were used in basal area growth and volume growth
multiple regressions in even-aged managed stands, searching...
This study was conducted to determine the effects of
shipping stress on the immune system in domestic lambs (Ovis
aries) and to determine the potential of the thymic peptide,
thymulin, to reduce those effects of stress on the immune
system. Treatments consisted of no shipping (as unstressed
controls), shipping (as...
The HAPEX-MOBILHY regional experiment provided an significant opportunity to analyze
the partition of energy and distribution of water over land surfaces. The combination of
remotely sensed data and ground instrument networks over the large-scale in situ experiment
allowed investigation of spatial and temporal variation of such hydrologic parameters as the...
Commercial vats of Chardonnay and Pinot Noir were
inoculated during yeast fermentation with starter cultures
containing 10⁷ - 10⁹ cfu/ml of the malolactic bacteria
Leuconostoc oenos Erla and Ey2d in lots ranging from 55 to
4,000 gallons. Chardonnay inoculated with Ey2d completed
MLF in an average of 56 days at...
Pre-harvest sprouting in wheat costs farmers millions of dollars every year. Pre-harvest sprouting tolerance (PST) has minimized this problem, but improvement of PST is still necessary. Synthetic hexaploid wheats (synthetics) have been used as sources of
genes coding for many useful traits. Two studies evaluated the PST of a synthetic...
Soil pore size distribution and water characteristics are important for water storage, water movement, and soil-plant interaction studies. Laboratory determinations of water characteristics and pore size distribution are time consuming and costly. Investigators have proposed many models to predict them from routinely available data. Most of the models are related...
