The black-footed ferret is a meso-predator within the Great Plains region of North America. Before the 1900s, black-footed ferret populations were self-sustaining in large ecological patches throughout the geographical range of the Great Plains. During the 1900s, various factors such as the systematic extermination of prairie dogs (the primary food...
Variation in cheese quality due to geographic location is important to cheese producers, consumers, and retailers on a global level. Understanding the impacts of geographic location of cheese plants may be useful to businesses for marketing, cost reduction, and quality improvement. Many aspects of variation due to geography have been...
In some legislative bodies, the use of terms like climate change and global warming is frequently seen as taboo. In the United States, voters who identify as right-leaning have reported little concern about the environment or climate change. This lack of interest is mirrored by Republican legislators who often publicly...
Seven species of microorganisms indigenous to fish were inoculated into sterile fish muscle, obtained from Sebastodes alutus and Sebastalobus alascanus, and the production of total volatile acids (TVA) and total volatile bases (TVB) was determined during storage at 1 C. No production of TVA and TVB was noted in sterile...
Thermal oxidation of methyl oleate was studied over a range of temperatures from 50 C to 150 C for periods of time up to 30 min. Degradation was quantitatively followed by gas liquid chromatography (GLC) and liquid scintillation counting of the products of methyl oleate-U-14C heated under a stream of...
Dimethyl sulfide, acetaldehyde, isobutyraldehyde, furan, 2-furaldehyde, 2-acetyl furan, and ethyl furoate were produced when pureed strawberries were heated to 120° C. for 30 minutes. Shorter heating periods were sufficient to produce the first three compounds. With the exception of acetaldehyde, none of the heat-induced compounds were detected in unheated, pureed...
Studies involving freeze-dried methyl linolenate-gelatin foams indicate that the extent of lipid-protein interaction corresponds to the degree of autoxidation of the lipid fraction. It appears that approximately 11% of the malonaldehyde as defined by the 2-thiobarbituric acid test is firmly bound to the protein. The induction period of autoxidation is...
Pesticide chemists have recognized since the 1940's that ultraviolet light was deleterious to the insecticidal properties of certain compounds. However, it has been only within the last 15 years that a number of photodecomposition products of the chlorinated hydrocarbon
insecticides have been isolated and identified. The degradation of insecticides by...
