The behaviors of the alfalfa leaf cutter bee - seed
production system under imposition of several management
regimes were studied through the use of a simulation
model that contains mechanisms for the following
processes: 1) immature bee development and diapause; 2)
immature bee mortality; 3) female bee emergence; 4)
nesting...
Symbioses between microbes and multicellular eukaryotes are found in all biomes, and encompass a spectrum of symbiotic lifestyles that includes parasitism and disease, commensalism, and mutually beneficial interdependent host-microbe relationships. Regardless of outcome, these symbiotic lifestyles are governed by a complex molecular "courtship" between microbe and potential host. This courtship...
Acute lymphoblastic leukemia (ALL) encompasses a spectrum of lymphoid progenitors that have undergone malignant transformation and clonal proliferation at various stages of differentiation. Some cases of ALL have been documented to have prenatal origins and in particular neonatal exposure to various environmental pollutants is associated with increased disease risk, including...
Purpose
The study was designed to test the effectiveness of a counselor
training experience which used pre-recorded client statements as the
instructional medium. The principal objective of instruction was to
teach counselor trainees to differentiate between the affective and
cognitive content of client statements and to respond in ways which...
A population of the Douglas-fir cone moth, Barbara colfaxiana
(Kft. ), was studied on the Buckhead Seed Production Area, Oakridge,
Oregon, during 1971 and 1972. A method of estimating cone and
insect populations is presented. Factors contributing to the mortality
of B. colfaxiana are discussed, with resinosis being the critical...
Seasonal trends in water table level and soil moisture
for four plant community types within an irrigated eastern
Oregon riparian zone were described. Aboveground biomass,
species composition, litter, percent bareground and percent
basal cover of key plant species and life forms were measured.
The relationship between water table levels and...
Abdominal obesity is a part of insulin resistance syndrome that is closely
linked to increased risk of coronary artery disease (CAD). Because fat tissue acts as
an endocrine target and source of hormone production, increased metabolism or
production of chemical messengers in fat tissue may result in metabolic perturbations
that...
