Influence of commensal microorganisms on Clostridium botulinum type E.

Creator:: Patrick, Lui-sun Kwan
Abstract:: Achromobacter A43 produced a compound inhibitory to the outgrowth of Clostridium botulinum type E spores. The inhibitor could be produced in various laboratory media and the outgrowth of germinated spores was completely inhibited by 1/10th dilution of the A43 spent medium. Germination was not affected. The spores lost refractility in...

Interrelationships of Meloidogyne hapla Chitwood, 1949 with Heterodera schachtii Schmidt, 1871 on Beta vulgaris L.

Creator:: Jatala, Parviz
Abstract:: Self-interactions (effects of reinoculation with the same nematode) in Meloidogyne hapla and Heterodera schachtii on Beta vulpris at different levels of inocula with various population combinations were studied. In M. hapla, the only significant increase of galls was noted in treatments when 250+250 larvae were inoculated at 10-day intervals. Longevity...

Training and pattern recognition in layered automata

Creator:: Schmidt, Dietger Reinhardt
Abstract:: The project herein described, presents the results of an investigation in the relatively new and expanding field of computer stimulated learning machines for use in pattern recognition. A learning machine, one that benefits from its past experience was devised in computer program form. It may be described as a Piecewise-Linear,...

An evaluation in rainbow trout of biliary excretion of sulfobromophthalein and effects of biliary excretion on the toxicity of rotenone

Creator:: Schmidt, Dana C.
Abstract:: Biliary excretion has been of considerable interest in mammals but has not been extensively studied in fish. To understand the significance of biliary excretion in rainbow trout (Salmo gairdneri), two studies were conducted. The objective of the initial study was to evaluate the ability of rainbow trout to excrete a...

A comparison of student attitudes & learning in interdisciplinary approaches in selected Oregon occupational clusters

Creator:: Schmidt, Richard W.
Abstract:: Purpose The purpose of this study was to make a comparative analysis of student attitudes and learning in relation to the selected academic subject of English when it is applied to certain Oregon occupational clusters. The occupational clusters selected were agriculture, electricity-electronics, industrial mechanics, and stenographersecretarial occupations. Method The comparisons...

The effects of a mutation within vitamin E biosynthesis upon the development and function of the photosynthetic apparatus

Creator:: Sicher, Richard Charles
Abstract:: A new photosystem-II mutant of the green alga Scenedesmus obliquus D₃, strain PS-28, has been shown to lack a-tocopherol (vitamin E). The photosynthetic activity of dark grown samples of PS-28 is about 20% of the wild-type control. Culturing the mutant at low light intentisites (10⁴ ergs/sec-cm ²) stimulates photosynthetic activity...

The life history of Anisogramma anomala (Pk.) E. Müller (Diaporthaceae) and its pathological and epidemiological association with Corylus avellana L.

Creator:: Gottwald, Timothy Ross
Abstract:: Eastern Filbert Blight, caused by Anisogramma anomala (Peck) E. Miller, was first discovered in the Pacific Northwest in 1974. Orchard experiments suggest that the fungus completes its life cycle in two years. Infection takes place from mid-January to May, mainly through mite-galled-buds infested with an Eriophyid mite, Phytocoptella avellanae Nal....

Movement of elemental constituents in sagehill loamy sand treated with municipal waste

Creator:: Halvorson, Gary Alfred
Abstract:: Metropolitan solid wastes and sewage sludges present a serious disposal problem for many communities. To assess the feasibility of disposal or utilization of these waste products on soils, a study was initiated to evaluate plant growth and soil elemental interactions on a loamy fine sand treated with metropolitan waste. Shredded...

Interstitial fluid mixing in estuarine benthic sediments

Creator:: Boyce, Allen R.
Abstract:: A method of measuring interstitial fluid mixing rates for evaluation of exchange between pore water of estuarine benthic sediments and the overlying water in a bay is presented. Pore water movement is monitored by reducing conductivity of the interstitial fluid within a zone of the benthic sediment to a depth...
