Escape from parasites in their native range is one of many mechanisms that can contribute to the success of an invasive
species. Gnathiid isopods are blood-feeding ectoparasites that infest a wide range of fish hosts, mostly in coral reef habitats.

This study investigated the influence of microwave and
broiling cooking methods on quality parameters of portion size
cuts of beef semitendinosus muscle subjected to pre-rigor
pressure treatment. The pre-rigor pressurized beef was compared
to conventionally processed portion size cuts. Juiciness,
tenderness, and flavor were evaluated by objective and
subjective tests....
A series of field experiments conducted at the Lewis-Brown horticulture farm at Oregon

ornamental shrub beds. Two natural products, corn gluten meal (CGM) and
meadowfoam seedmeal (MFS), were used along with two synthetic products, prodiamine

Psychosis is defined as a syndrome which is associated with many mental disorders, not a specific disorder itself. Psychosis generally produces delusions and hallucinations and...
The objective of this research was to indirectly determine the
existence of a possible retinal-endocrine pathway activated, or
Inhibited, by artificial fluorescent light as evidenced by it subsequent
effects on bone metabolism. Forty-eight male Long-Evans post-breeder
rats, half of which were bilaterally orbitally enucleated, were
used in this experiment. A...
A study of nutrient intakes was conducted on the Southwest
Oregon non-reservation Indian population during June and July of
1980. Participating households were selected by random methods from
a Southwest Oregon Indian Health Project listing of Indian
households in the six-county area. Twenty-four-hour dietary recalls
were obtained by interview method...
Developmental changes in the storage organ of Brassica
campestris L. were followed from the organization of the embryonic
radicle and hypocotyl to the mature storage organ. Three independent
primary meristems gave rise to the cortex, the stele, and the
root cap-epidermis. The primary development is typical of the
Cruciferae. Cambial...
