Toxicity of some commonly used pesticides to Trioxys Pallidus and its establishment in filbert orchards of Willamette Valley

Creator:: Saeed, Mohammad
Abstract:: A parasitic wasp, Trioxys pallidus Haliday (Hymenoptera: Aphidiidae) was imported from Europe and initially released against the filbert aphid Mvzocallis coryli (Goetze) in hazelnut (filbert) orchards of the Willamette Valley, Oregon beginning in 1984. In the present study, I investigated the establishment rates of this parasitoid. A total of 13...

Status, distribution and seasonal variation of filbert aphid resistance to selected insecticides in the Willamette Valley, Oregon

Creator:: Katundu, Juma
Abstract:: Levels of resistance to six selected insecticides of eleven field populations of the filbert aphid Mvzocallis coryli (Goetze) were determined by using the leaf-dip residue technique. Test insecticides included compounds widely used in commercial filbert orchards, namely, carbaryl, diazinon, endosulfan, phosalone, fenvalerate and oxydemetonmethyl. Aphid samples were collected within a...

Preliminary design and analysis of a rotating bubble membrane radiator for space-based nuclear power systems

Creator:: Webb, Brent Jonathan
Abstract:: The development of a novel high temperature space radiator is described. A Rotating Bubble Membrane Radiator (RBMR) combines the best features of heat pipes and droplet radiators while avoiding their negative attributes. The RBMR offers light weight, self deployment, ease of startup and its performance is less affected by acceleration....

Senecio jacobaea : toxicity and effects on mineral metabolism in animals

Creator:: Swick, Robert Alphonso
Abstract:: Several experiments were conducted to examine the toxicity of Senecio jacobaea (SJ) in animals resistant to pyrrolizidine alkaloid (PA) intoxication and to determine the extent of alterations in mineral metabolism as a result of SJ intoxication. Inclusion of SJ into diets containing added copper (Cu) resulted in increased (P<.01) liver...

The physiological effect of posture on cycling

Creator:: al-Haboubi, Muhammad
Abstract:: The objective of this research was to investigate the physiological effects of body posture on cycling. The familiar positions of bicycle riding have been the touring posture (hands stretched on top handlebar) and the racing posture (hands bent at the elbow, with the back horizontal). However, a relatively new stance...

An interpreter for a very-high level language (BAGIT)

Creator:: Chou, Kuo-Wei
Abstract:: The purpose of this project is to design and implement an intermediate language interpreter for a very high level language called Bagit. The Bagit compiler produces Bcode, and this in turn is interpreted by the program described in this report.

Physiological, biochemical, and genetic studies on the [delta]²⁴ sterol methyltransferase of Saccharomyces cerevisiae

Creator:: McCammon, Mark Thomas
Abstract:: The role of the yeast S-adenosylmethionine: Δ²⁴-sterol-C-methyltransferase (SCMT) in sterol metabolism was investigated. Structural analogs of S-adenosylhomocysteine were tested for inhibition of the SCMT enzyme. A wide inhibitory range by these compounds was observed, indicating which structural features of the parent compound are important for binding to the enzyme. The...

The relationship of dietary intake to blood vitamin B₆ in oral contraceptive users

Creator:: Hoaglund, Judith Ann
Abstract:: Oral contraceptive (OC) users frequently have lower vitamin B₆ status than non-oral contraceptive (NOC) users. However, normal dietary intake, a possible factor, has not been adequately studied. Therefore, 26 OC users and 25 NOC users, of college age, were compared with respect to dietary intake of vitamin B₆ and blood...

Price elasticities in commodity trade models and external trade statistics

Creator:: Emami, Ali
Abstract:: The purpose of this study is to investigate the role of the source of the external trade statistics in measuring the price responsiveness of foreign demands and relative price competitiveness of the major exporting countries in trade of agricultural commodities in international markets. In particular, the papers included in this...
