Characterization of Carboxylic Acids on Hafnium Oxide Thin Films

Creator:: Ray, Peter William
Abstract:: Hafnium Oxide thin films has had growing attention due hafnium oxide being used as a gate dielectric for MOSFET transistors and a potential next generation photoresist for sub 20 nm patterns. Extreme Ultra-Violet (EUV) lithography has been identified as the primary candidate technology for generation of sub-20 nm patterns. Current...

Evaporation of an ammonia chloride stream to produce aqueous ammonia and 40 wt % calcium chloride

Creator:: Ivey, Thadeus J.
Abstract:: Production of calcium chloride (CaCl2) and aqueous ammonia (NH4 +) from the ammonia chloride (NH4Cl) stream in the Solvay process was studied using an Ammonia Recovery Tower to produce 29 wt % aqueous ammonia and 40 wt % CaCl2 from the process feed stream or the tower bottoms stream. OLI,...

Comparison of Dorper and Polypay as maternalsire breeds for reduced input lamb production

Creator:: Haas, Joel D.
Abstract:: During years 2005, 2006, and 2007 ewes of predominantly Polypay breeding were bred to either Dorper or Polypay rams for spring lambing. Ewes were assigned to single-sire mating groups based on age and genotype. Internally generated replacements were added to the flock for the 2007 lambing season and bred to...
Resource Type:: Masters Thesis
Full Text:: . Dorper- mated ewes gave birth to 0.14 more lambs than Polypay-mated ewes, suggesting a ram breed

Sheep breed evaluation : grazing behavior, condition scores and lamb production

Creator:: Berggren-Thomas, Bruce
Abstract:: I. The Effects of Sire Breed, Forage Availability and Weather on the Grazing Behavior of Crossbred Ewes. Thirty nonpregnant, nonlactating crossbred ewes, six per sire breed (Suffolk, Clun Forest, Dorset, Polypay and Border Leicester), were observed grazing together in a 0.87 ha grass-clover pasture for six days over a two-week...

Biology of the microsporidan parasite, Pleistophora sp., in three species of Crangonid sand shrimp

Creator:: Breed, Gail Miner
Abstract:: The microsporidan Pleistophora sp. is a common parasite of Crangon franciscorum, C. nigricauda, and C. stylirostris in the vicinity of Yaquina Bay, Oregon. Characteristics of the parasite are described. Skeletal muscle was the only host tissue infected. The seasonal prevalence and intensity of the parasite in crangonids are described, based...

Conversion of glucose to hydrogen gas by supercritical water in a microchannel reactor

Creator:: Goodwin, Aaron K.
Abstract:: Glucose was gasified in supercritical water within a microchannel reactor at 650°C 750°C, and 250 bar to yield H2 rich gas with a low concentration of CO. The feed glucose concentration was 0.1 M. Two microchannel reactor configurations were tested at fluid residence times ranging from 0.5 sec to...

Genetic and physiological factors associated with gonadotropic and thyrotropic hormone content of sheep pituitaries

Creator:: Plotka, Edward Dennis
Abstract:: Data were taken from 47 animals consisting of five breeds: Border Cheviot, Columbia, Dorset Horn, Suffolk, and Willamette. Both sexes were represented in each breed, although in unequal numbers. The pituitaries were assayed for gonadotropic and thyrotropic hormone content by injecting a suspension of the macerated gland in saline into...

Development of a new mixture proportioning method and assessing the influence of material characteristics on flowing concrete mixtures

Creator:: Hendrix, Greg
Abstract:: Cast-in-drilled-hole (CIDH) piles are often constructed to depths that are inaccessible to internal vibration of the concrete. Internal vibration is necessary to consolidate the concrete and, if not performed, then typically inspection pipes are necessary to detect the presence of voids in CIDH piles. Void detection is critical to assessing...

The effects of intraspecific plant competition and insect herbivory of ragwort (Senecio jacobaea) populations

Creator:: Fitzpatrick, Greg S.
Abstract:: I conducted field studies to determine the effect of insect herbivory and intraspecific plant competition on ragwort Senecio jacobaea. The objectives were to determine the patterns and causes in the distribution of the ragwort flea beetle Longitarsus jacobaeae foraging among varying densities of ragwort, to measure the behavioral and numerical...
