Sustainable energy for Galena, Alaska: Timber Harvest Management Plan

Creator:: Kalke, Timothy R.
Abstract:: Increased energy costs have prompted the rural village of Galena, Alaska to explore viable alternatives for heat and power generation. Continued dependency on petroleum products will cause the community’s economic driving force, the Galena Interior Learning Academy (GILA), to face uncertain operability. A wood-fired boiler is scheduled to be installed,...

Effects of fiber electrostatic cling and moisture regain on Timothy grass pollen attraction

Creator:: Vaughn, Reyna J.
Abstract:: People will spend a large amount of their lifetime indoors where the air is filled with both indoor and outdoor allergens. Exposure to allergens can have a range of effects on the health of building occupants. Textiles make up a vast majority of the surfaces, such as draperies, sofas, pillows,...

Influence of previous cattle and elk grazing on the subsequent diet quality and nutrient intake rate of cattle, deer, and elk grazing late-summer mixed-conifer rangelands

Creator:: Damiran, Daalkhaijav
Abstract:: Four studies were conducted on late-summer diet quality and quantity of cattle (Bos taurus), mule deer (Odocoileus hemionus hemionus), and elk (Cervus elaphus) in response to prior grazing by cattle and elk on mixed-conifer rangelands and on related research techniques. In our first study we assessed a photographic technique to...

Management of stockpiled forages and optimal use of supplements by beef cattle while consuming low-quality forages

Creator:: Suverly, Norman A.
Abstract:: Three studies were conducted to evaluate: 1) rotationally grazed forage for late-summer stockpiling; 2) effects of lactation on self-fed supplement intake; and 3) influence of cow age on hand-fed supplement intake. For the first study, treatments consisted of non grazed, 2X and 3X grazed. Crude protein of forage grazed 3X...

Effects of forage quality and type of protein supplement on intake and digestibility in beef steers and performance of postpartum beef cows

Creator:: White, Jenny J.
Abstract:: Two experiments were conducted to evaluate the effects of forage quality and supplemental undegradable intake protein (UIP) level on intake, digestibility, and performance of beef cattle. In Exp. 1, five ruminally cannulated steers (BW = 456 ± 6 kg) were used in a 6 x 5 incomplete Latin square with...

Influence of stocking density on grazing beef cattle performance, diet composition foraging efficiency, and diet quality on a late-spring early-summer native bunchgrass prairie

Creator:: Wyffels, Samuel A.
Abstract:: This study evaluated the influence of cattle stocking density on botanical composition of diet, diet preference, and cattle performance on the Zumwalt Prairie in Northeastern Oregon. In each of two years, 192 cow-calf pairs (549.27 kg, BCS = 4.89) and 48 yearling heifers (383.34 kg, BCS = 5.02) were stratified...

Quantities of prostaglandins in whole and extended bovine semen and their potential effect on fertility following insemination

Creator:: Jaeger, John Ralph
Abstract:: Our objectives were to determine 1) the concentration of prostaglandin F2α (PGF2α) in whole and extended bovine semen, 2) if concentrations of prostaglandins in extended bovine semen are correlated to fertility, and 3) if PGF2α administered at the time of artificial insemination would improve conception rate. Concentration of PGF2α tended...

The effects of timber harvest and herbivory on understory vegetation and composition of beef cattle diets on forested rangelands

Creator:: Walburger, Kenric J.
Abstract:: The objectives of the experiment were to: 1) determine the relationship between overstory canopy cover and ungulate herbivory on understory production composition and diversity and 2) determine the effects of timber harvest, ungulate herbivory and season of use on botanical composition and nutritional quality of beef cattle diets. Three randomly...

SCALE 6 (TRITON) Simulations of Fission Product Gamma Line Emissions and their Comparison to Plutonium and Uranium Measurements

Creator:: Sanchez, Timothy J.
Abstract:: Thin foil samples of special nuclear materials (SNMs) were irradiated for 60s using a Mark TRIGA II reactor, and their associated gamma emissions were recorded with a count time of 60s following irradiation. A rapid pneumatic transfer system was used to irradiate the samples in front of beam port #4....

A remotely operated, autonomous wave energy converter system

Creator:: Lewis, Timothy M.
Abstract:: The potential for electric energy generation from ocean waves is substantial and much research is being conducted on the conversion process as a renewable, grid-connected, power source. Some of the same attributes that make wave energy harvesting attractive as a grid-connected source also make it attractive as a remote, or...
