Genetic analysis of reproductive performance of Rambouillet sheep
(1987)
Data from a purebred Rambouillet range flock between the years of 1919 and 1985 were analyzed to determine: the relationship of age, body weight, birth type, sex of natal twin on lamb and fleece production, and longevity; ...
Aspects of quantitative cancer dose-response modeling and the role of the lognormal distribution
(1988)
Quantitative cancer dose-response models have been the subject of much research. The multistage model is currently the most widely used cancer dose-response model. Several characteristics of the multistage model iterative ...
Swarming behavior of Psorophora columbiae (Dyar and Knab) in East Texas ricelands
(1984)
Highly sensitive Infra-red video recording equipment was used to observe and record marker swarming behavior of natural populations of Psorophora columbiae (Dyar and Knab) in the field. Swarming was a predominantly male ...
Digestion dynamics in white-tailed deer
(1988)
Thirteen standard metabolism trials were conducted from May 1986 to June 1987 with white-tail deer (Odocoileus virginianus) utilizing a pelleted diet or one of 3 browse species (guajillo, Acacia berlandieri; blackbrush ...
Kleingrass growth and utilization under early-season grazing
(1989)
The response of kleingrass standing crop, tissue fluxes and tiller dynamics, and the response of livestock gains and intake to early-season grazing treatments were investigated a t McGregor, Texas. The study evaluated the ...
Study of marine sediment drag forces on offshore pipelines
(1987)
Soft marine sediments move in response to gravity forces and bottom pressures produced by storm waves. These sediment movements produce forces on ocean structures, such as offshore platforms and marine pipelines, which are ...
Molecular characterization of the patatin multigene family of potato
(1987)
A cDNA library was constructed from poly A mRNA isolated from membrane-bound polyribosomes of developing tubers. From this library, two groups of clones for the major tuber protein, patatin, were isolated. The complete ...
Allochthonous salt sheets in the Alaminos Canyon region, northwest Gulf of Mexico : present configuration and processes of emplacement
(1989)
Numerous physical and mathematical models have simulated highly mature diapirism in which low density material moves upward through more dense material and then spreads out as a layer known as a canopy (Jackson and Talbot, ...
Coccoliths from the Cretaceous-Tertiary boundary of the Walvis Ridge, South Atlantic : biostratigraphic and paleoecological implications
(1989)
Biostratigraphy, diversity, and oxygen and carbon isotopes are determined for calcareous nannoplankton from four sections of Cretaceous-Tertiary boundary interval sediments on Walvis Ridge in the South Atlantic (DSDP Sites ...
Studies on the transport and storage of indole alkaloids by Catharanthus roseus
(1988)
The transport and storage of indole alkaloids by mesophyll protoplasts of Catharanthus roseus (L.) G. Don was characterized. Uptake of alkaloids by mesophyll protoplasts was found to have two components: a rapid, non-specific ...
