A survey of federal and state agencies was conducted to determine
the future need for water-quality data. This survey was used
as the basis for constructing a water-quality data aquisition system
applicable to any river basin. This study outlines the major components
of an automatic water-quality monitoring system.

Myxozoans are microscopic parasites, related to corals and jellyfish. Most Myxozoa probably have two-host lifecycles that require a vertebrate (typically fish) and invertebrate (annelid or bryozoan). However no life cycle is known from the Sphaerospora lineage.
I hypothesized that the life cycle of Sphaerospora elegans, a myxozoan parasite of three-spined...
While sophisticated plans have been adopted nationally and globally to increase bicycling’s share of daily commutes, safety concerns have negatively impacted targeted bicycling growth. Specifically, truck traffic plays a pivotal role in bicyclists’ perceptions of safety and comfort, because of the severe consequences of bicycle-truck collisions. Several types of engineering...
Cultural resource inventories have identified,205 individual sites
on public land along the Lower Salmon River, Idaho. These sites
represent a rich and diverse record of the human occupation and
utilization of the river canyon during the past 10,000 years. Each
of these 205 sites contains its own unique record of...
Changes in the type and amount of plant inputs can occur gradually, as with succession, or rapidly, as with harvesting or wildfire. With global change it is anticipated that both gradual and immediate scenarios will occur at increasing frequency. Changes in vegetation inputs alter the quality and quantity of soil...
Essential oils have numerous chemical and therapeutic applications. Some oil extraction methods, including steam distillation, require a large energy input. An alternative technique with a lower energy demand is the extraction of oils using supercritical liquid carbon dioxide (CO2), which extracts essential oils with minimal environmental impact. While this often...
Algae have shown great potential as a source for renewable fuels. However, current production schemes have not been able to prove a sustainable energy return on investment due in part to the high costs of nutrient addition and the energy required for drying the biomass. Integrated algae-dairy production systems have...
Oregon State University swine herd records of four genetic
groups were analyzed to determine: (1) the association of occurrence
of a small litter (≤ 7) at birth with size of subsequent litters
for gilts and sows, separately; (2) the effect of parity, genetic background
and litter size on mean birth...
Treatment of round shrimp (3 days post-catch) in 6% condensed
phosphate solution at temperatures ranging from 39 (3.9°C) to 86°F
(30°C) reduced meat yield derived by mechanical peeling from 30.0
to 16.4% (wet wt.) according to the linear function y = -.2787 x +
42.7262 (P>.005). Condensed phosphate treatment at...
