Ring expansion reactions of alkoxides and their application toward synthesis of large ring hormone models

Creator:: Seitz, Earl Philip
Abstract:: The potassium salts of a series of 1-vinylcycloalk-3-en-l-ols were found to undergo ring expanding [1, 3]-sigmatropic shifts at 25° when dissolved in hexamethylphosphoramide (HMPA) or 1, 2-dimethoxyethane (DME) with 18-crown-6. The yields and reaction rates were compared with those of the corresponding Siloxy-Cope ring expansions. These anionic cases showed about...

The impact of three stocking intensities and four grazing treatments on the carbohydrate reserves of perennial ryegrass (Lolium perenne L.)

Creator:: El Hassan, Babiker Ahmed, 1940-
Abstract:: A study was conducted during 1974 and 1975 to evaluate the impact of stocking intensity and season of grazing upon carbohydrate concentration, biomass of storage organs, and total carbohydrate per plant in the roots and crowns of perennial ryegrass (Lolium perenne L.) in improved rangelands in Western Oregon. The stocking...

Food and habitat partitioning in two groups of coexisting Accipiter

Creator:: Reynolds, Richard T.
Abstract:: Sharp-shinned Hawks (Accipiter striatus), and Cooper's Hawks (A. coo erii) in the conifer forests in northwestern Oregon and A. striatus, A. cooperii, and Goshawks (A. gentilis) in the conifer forests of eastern Oregon were syntopic during the nesting season. In this study density of nests, nest success, and utilization of...

The effect of various additives on nutritive value of ryegrass straw silage

Creator:: Shultz, Thomas Anthony
Abstract:: Observations were made on silage pH, chemical composition and 24hr in vitro dry matter digestion (IVDMD) to evaluate effects of various additives ensiled with annual ryegrass straw. Additives were compared in factorial designed trials utilizing .95 1 glass jar silos. Selection of additives used in each subsequent trial was based...

Aluminum toxicity studies in rice (Oryza sativa L.)

Creator:: Martinez-Racines, Cesar P.
Abstract:: A nutrient solution technique developed for wheat was used to determine tolerance of rice cultivars to aluminum (Al) toxicity. Pre-germinated rice seed was placed on top of a screen and allowed to grow on the Al-free solution for 72-96 hours or until the primary root was 2-3 cms long. Seedlings...

Visually perceived nonverbal behaviors of teachers and their relationship to affective responses of students

Creator:: Kelly, Joseph Richard
Abstract:: This investigation was designed to measure certain visually perceived nonverbal behaviors of teachers in an effort to learn the relationships between these behaviors and the affective responses of students to the teachers, To this end, teachers were videotaped, and the tapes were shown to students for their affective responses. Thirty...

Performance of some tests for bivariate independence, interchangeability, and equality of distributions of ratios

Creator:: Ferguson, Nancy Lo
Abstract:: The purpose of this thesis is to derive and compare asymptotic performances of certain tests of independence, interchangeability and equality of the distributions of_ratios Y/X for positive variates and Y with joint c.d.f. H(x,y) of particular forms. Three bivariate families, Morgenstern, Plackett, and Moran, are considered which permit marginal c.d.f.'s...

Cattle grazing habits and movements related to riparian habitats and forested ranges with inference to acute dietary bovine pulmonary emphysema (ADBPE)

Creator:: Roath, Leonard Roy
Abstract:: Grazing on the mountainous forested ranges of the Camp Creek Unit, Malhuer National Forest, was typified by irregular distribution of free-ranging cattle. A combination of management and physical, topographic constraints caused cattle to concentrate on the riparian zone early in the grazing season in 1977 and 1978. A large percentage...

Stability of convective flows in porous media

Creator:: Ghandour, Nabil Nassib
Abstract:: The stability of fluids in porous media subject to various physical and geometrical conditions is studied here. Criteria for the onset of convective motions are given in terms of critical temperature gradients or heat sources. The general method used involves the linearization of the field equations about the hydrostatic solutions...
