This thesis analyzes two systems that can meet low-grade heating
and/or cooling demands by operating in conjunction with thermal-electric
power plants. At the application site, one of the systems, HPS, has
water-to-air heat pumps that are connected to the supply and return
lines of a plant-to-user loop. During heating, the...
Regionalized variable analysis has been used to study
a number of meteorological and hydrological variables
including precipitation (Delhomme and Delfinier, 1973),
streamfiow (Villeneuve et al., 1979) and hydraulics of
groundwater aquifers (Gambolati and Volpi, 1979). In the
research work reported in this thesis, an attempt was
made to characterize the...
The size of elk herds in Eastern Oregon has become a controversial
issue. Trade-offs exist between the numbers of elk and domestic
livestock on a given area of land, and also between elk and commercial
timber harvesting policies. Disputes arise from differing views as
to proper use of the natural...
Our objectives were to determine if dietary cation-anion difference (DCAD) and source of anions influence periparturient feed intake and milk production, and to characterize feeding behavior of dairy cattle during the transition period. Diets differed in DCAD (cationic or anionic) and anionic supplement (BioChlor®, Fermenten®, or anionic salts), and were...
This study attempted to answer the following question: What instructional methods should dietetic preceptors use to help dietetic interns meet the performance requirements specified by the American Dietetic Association (ADA, 1991) for entry-level dietitians? A national sample of 170 dietetic preceptors was surveyed. Ninety provided usable information to examine both...
Four experiments were conducted to determine oxytocin concen tration of bovine luteal tissue at different stages of the estrous cycle and to study the effects of prostaglandins F₂α (PGF₂α), E₂ (PGE₂), luteinizing hormone (LH), cycloheximide, colchicine and cytochalasin B on oxytocin synthesis and release in vitro. In experiment 1, luteal...
The purpose of this qualitative research study was to describe the experiences of secondary teachers who were actively involved in positions of teacher leadership in their schools and to discover the meaning that leadership activities had for them in their work. The informal teacher leaders performed their leadership functions in...
This study was conducted to determine the relationships among the
linear type traits of rump angle, rump width, rump length, rear legs
side view, rear legs position, rear legs rear view, tailhead, vulva
angle, mobility, pasterns, foot angle, and toes with reproductive
performance (days open and times bred) in Holstein...
