The effect of entrance configuration on local heat transfer coefficients in subsonic diffusers

Creator:: Stoffel, Edward Oswald
Abstract:: The effects of round, square, and reentrant entrances on flow regimes and local heat transfer coefficients were determined using a symmetrical, plane-wall two-dimensional, subsonic air diffuser with one of the diverging walls heated and maintained isothermal. Flow and heat transfer studies were made at total divergence angles ranging from 0...

Puberty development and reproductive performance in beef heifers fed rations supplemented with Oregon by-product feeds

Creator:: Oswald, Keely E.
Abstract:: In the majority of management scenarios, it is imperative that beef replacement heifers calve at two years of age. In order to achieve this goal, yearling heifers should reach 60 to 65% of their mature body weight by 13 months of age. Feed costs represent 75 to 80% of the...

Effects of fertilization at the time of planting on field performance of 1+1 Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings

Creator:: Alzugaray Oswald, Patricio Javier
Abstract:: To study the combined effects of seedling quality and fertilization at the time of planting, three experiments were established in western Oregon during the winter of 2000. The first experiment investigated the effect of preplanting rootvolume and fertilization rate on the field performance of 1+1 Douglas-fir seedlings during two growing...

A revision of the Nearctic species of Sympherobius Banks (Neuroptera: Hemerobiidae)

Creator:: Oswald, John D. (John David)
Abstract:: The Nearctic species of the genus Sympherobius Banks are revised. Seventeen species are recorded from the region. Two new species, S. constrictus and S. quadricuspis are described from California and Arizona respectively. Four new specific synonyms are proposed (junior synonym(s) first): S. brunneus Nakahara and S. stangei Nakahara = S....

Geology of the Seaside-Young's River Falls area, Clatsop County, Oregon

Creator:: Tolson, Patrick Marion
Abstract:: Eight Tertiary geologic units crop out in the Seaside-Young's River Falls area, including late Oligocene to early Miocene Oswald West mudstones; Angora Peak sandstone and Silver Point members of the middle Miocene Astoria Formation, and middle Miocene Depoe Bay and Cape Foulweather Basalts. Three new lithologically distinct units, the 'J'...

Investigation of combustor and fuel preparation requirements for a combined-cycle wood fired power plant

Creator:: Bauer, Timothy Lee
Abstract:: The Pacific Northwest is a particularly good candidate for a power plant fired with wood since the wood products industry is so important in the area. The combined cycle concept for such a plant has increased in popularity due to the generally greater efficiency of the gas turbine part of...

A study of some physiological properties of ovine and bovine utero-ovarian arteries

Creator:: Kuhl, Lynda Marie
Abstract:: The utero-ovarian vasculature of domestic animals has been a popular research subject, especially concerning the roles of the uteroovarian artery and vein in the unilateral luteolytic phenomenon demonstrated in these animals. No reports in the literature, however, have been found regarding the smooth muscle physiology of these vessels. The present...

Comparative epidemiology of Phytophthora diseases of Rhododendron

Creator:: Taylor, Clare Rebecca
Abstract:: Rhododendron species are host to many Phytophthora species and are an important crop in the nursery industry. The foliar epidemiology of twelve Phytophthora diseases on Rhododendron was studied in field and growth chamber experiments on two Rhododendron cultivars. The relative aggressiveness of Phytophthora spp. was assessed using disease incidence, severity,...

Real-time bandwidth compression using Hilbert transforms

Creator:: Bradley, Richard William
Abstract:: This paper presents a theoretical study of real-time bandwidth compression systems using the Hilbert transform and associated analytic signal concept. An analytic signal is defined as u(t) = s(t) + [superscript ¯]js(t) , where [superscript ¯]s(t) is the Hilbert transform of the signal s(t). A complete discussion of the properties...

Design criteria for waste water lagoons in Oregon

Creator:: Putnicki, George John
Abstract:: Waste water lagoons have been used as a satisfactory means of treating domestic and certain industrial wastes in many parts of the country. Many of the parameters that govern the applicability of this type of treatment process are climatic in nature, and critical evaluation of local climatic conditions, as well...
