The aflatoxins, carcinogenic and toxic mold metabolites
of Aspergillus flavus, were isolated and determined
in cottonseed meal and other feedstuffs. This new
quantitative method uses an acetone soxhlet extraction to
remove the toxins from the defatted meal. The residual
triglycerides, phospholipids and pigments were removed
from the acetone by filtration...
The assessment of optimum nitrogen (N) fertilizer need for winter wheat (Triticum
aestivum L.) is important for economic and environmental sustainability. A comprehensive understanding of fertilizer N requirement depends on estimation of the quantity of N needed by the crop versus that supplied by soil.
The objectives of this study...
Seashore paspalum (Paspalum vaginatum Sw.) is an important warm-season perennial turfgrass, known for its tolerance to salinity. Turfgrass is used for homes, municipalities, sod farms, resorts, and sports fields. Seashore paspalum has historically been planted in sub-tropical and tropical climates because of its heat tolerance. Seashore paspalum could become an...
The travel cost method of deriving demand and value of recreation
does not include fixed costs of recreational durable goods purchases
or allow for supply restrictions on the number of suitable
sites available. The omission of these two real-world situations
results in derivation of demand curves which are more inelastic...
Factors affecting animal detection and identification
by remote sensing are compiled and described. Habitat preference
and animal behavior are shown to be the variables that most
influence detection and identification. An analysis of the
basis of application of thermal infrared sensors to animal
detection covering the principles of infrared radiation...
Selected parameters that affect crude toxin production in both
primary culture (growing cell culture) and resting culture were
examined during efforts to produce sufficient crude toxin for purification.
The parameters included carbohydrate and label source and
concentration, cell concentration, incubation time and temperature
and shaker speed. A higher yield of...
Increasing demands on earth resources require the need to
know how much resource is present. A new technology, which is
developing partially with the support of the National Aeronautics and
Space Administration, will help to inventory and monitor surface resources
in a more comprehensive manner than previously possible.
Research in...
The reactions of aldehydes with proteins are of nutritional and
physiological significance. The nutritive value of food materials can
be impaired by a reaction necessitating additional dietary protein,
and enzymes have been shown in vitro to be inhibited by reactions
with aldehydes.
Aldehydes present may arise from the autoxidation of...
