Chalkbrood is a mycosis of larvae of the alfalfa leafcutting bee,
Megachile rotundata (Fabricius). It is a serious threat to alfalfa seed
growers in western North America who use populations of this bee for
pollination. Basic studies were conducted to determine the etiology of
this disease and the course of...
Gene expression profiles of tissues and cell-lines can be powerful tools for documenting the genetic response to a particular treatment, such as stressors. However, there is a paucity of information on the genetic stress response in the brain. Therefore, we attempted to profile gene expression in the brain of juvenile...
The profile of the inner-tubing gas pressure for a tubular membrane aeration system was quantified. The correlations among the overall volumetric oxygen transfer coefficient (k[subscript L]a), the inner-tubing pressure, the tubing tightness, and the gas throughput are experimentally analyzed. A mathematical model was developed to describe the underlying phenomena. The...
While seemingly harmless, stereotypes can play a significant role in prejudice and discrimination. In two studies, we examined stereotypes of Asian American women and how they may vary with different clothing types. We used a mixed factorial design with a sample of college students from a U.S. university. In the...
Metal-organic frameworks are promising novel materials for gas storage and separations because of their extremely high internal surface area and their modular structures based on metal nodes and organic linker molecules. Due to their modular design, it is possible to finely tune a structure for optimal storage of a specific...
Ninety-six mature pregnant Hereford cows were allotted to three
replications with four treatments. Pregnancy was determined by rectal
palpation prior to the initiation of the study. The cows were
artificially inseminated the previous spring, beginning the end of
May, over a period of 42 days to a single Angus sire....
The sea offers a wide variety of potentially useful resources. Marine algae have been a rich source of structurally unique natural products showing diverse biological properties. The current need to develop new antifungal, antibiotic, anticancer and antiviral drugs has prompted intense research efforts into the discovery, isolation and structure determination...
Spotted wing Drosophila (SWD), Drosophila suzukii (Diptera: Drosophilidae), is a pest of small and stone fruits that is widely distributed across much of the United States, Canada, Europe and Asia. Unlike other members of the Drosophilidae that only lay eggs in overripe or rotting fruit, SWD infest ripening and ripe...
The study examined dimensions of the family context associated
with variations in parent involvement and parent perceptions of children's
school achievement using data from 1,085 male and 2,239 female
respondents with a child between the ages of 5 and 18 years collected in the
1987-88 National Survey of Families and...
