Intuitive Concepts In Elementary Topology, Gary Rothwell

Honors Theses

My hour special study in intuitive topology originated in a curiosity of what exactly topology was and how it might be related to physics, my field of interest. The book I used was, Intuitive Concepts in Elementary Topology, by B.H. Arnold. This book is designed as a sophomore-junior level three hour course. Needless to say, I didn't quite cover the whole book in an hour a week. I mainly stuck to the intuitive concepts. Intuitive topology is dealing with more physical objects where the point set topology involves set theory; their unions, intersections and subsets.

Infrared Spectrophotometric Analysis Of Serum Triglycerides, Gerald J. Miille

University of the Pacific Theses and Dissertations

In recent years elevated levels of serum triglycerides have become of increasing importance in the field of medical technology. Abnormally high triglycerides have been claimed to be a major cause of numerous diseases and illnesses. Fredrickson and his associates (7, 15) have introduced a system for classifying hyperlipidemia and in all classes elevated triglycerides is a major laboratory finding. Disorders include obesity, diabetes, pancreatitis, xanthomatosis, hypothyroidism, and liver and kidney diseases; but most important is atherosclerosis

Some work has been done in the development of new methods of serum triglyceride analyses. The most advanced work makes use of an "automated …

Cross Sections For Photoionization Of The 6²P-Fine Structure Levels Of Cesium, John Daniel Jones

Doctoral Dissertations

"The cross sections for photoionization of excited cesium from the 6²P_3/2- and 6²P_1/2-fine structure levels have been measured using a triple crossed-beam apparatus. Two photon beams, one for excitation and one for ionization, impinge upon an atomic beam and produce ions at the point of intersection. The relative cross section is determined from a knowledge of the ion count rate and the relative photon flux of the ionization light. The results are normalized to available theoretical calculations and compared with recombination measurements in cesium plasmas. The present cross sections are found to decrease with …

Kinetic And Thermodynamic Acidities Of Selected Weakly Acidic Hydrocarbons, Darrell R. Strait

Doctoral Dissertations

"The kinetic and thermodynamic acidities in methanol for bromoform and phenylacetylene have been determined at various temperatures. The thermodynamic acidities of phenylacetylene were obtained through a quench method which involved tritium tagging of the phenylacetylene anions present at equilibrium. With the use of this method, a pK_a of 18.34 for phenylacetylene at 0ºC was obtained. Through the use of these acidities, it was shown that the kinetics for these proton exchange processes are not diffusion controlled.

Isotope effects ( k_H/ k_D) were obtained for chloroform, bromoform and phenylacetylene at three temperatures (0ºC, -10ºC and -20ºC). …

Experimental Summaries - Plant Research

The objectives of the field experimental programme for 1974 were to - 1) Evaluate a technique to measure pasture loss as a result of doublegee infestation at Merredin, Wongan.Hills and Chapman. 2) Evaluate the effect of cultural and herbicide treatment combinations on the magnitude and distribution of viable doublegee seeds in the soil at Avondale, Merredin, Wongan Hills and Chapman. 3) Measure the magnitude and distribution of viable doublegee seeds in the soil from paddocks representing each year of a two crop, plus three year pastureley rotation at Avondale, Merredin, Wongan Hills and Chapman. 4) Screen herbicides for selective control …

Pasture Deterioration - High Rainfall Areas, D J. Gillespie

Experimental Summaries - Plant Research

a. Pasture deterioration - High rainfall areas - A farm at Karridale (near Augusta) exhibiting "classic" pasture deterioration symptoms was closely monitored throughout 1974. This farm has paddocks ranging from relatively newly sown pastures with a high clover percentage, few weeds and high dry matter production (resown 1973 and 1974), through to extremely poor pastures with as little as 3 % clover and a weed component of over 80% (resown 1970 and 1971)... b. Midland B competition studies (69Mt19) -This grazing trial was sown in 1969 to plots of pure Midland B, pure Woogenellup and to three mixtures of the …

Weed Trials 1974 Summary - Annual Ryegrass Control - Wild Oats - Cereal Tolerance To 2,4-D - Annual Ryegrass Toxicity, G. A. Pearce

Experimental Summaries - Plant Research

A herbicide trial and demonstration was commenced in 1973 and the treatment repeated in 1974. the objective was to control the annual ryegrass which was the dominant species and allow the scattered plants of sub clover to re-establish a clover dominant pasture. (See table) Despite the high reduction of seed stalks formed on some treatments in 1973 the ryegrass was only reduced by 50 per cent on the best treatment in 1974, The reduction in seed production in 1974 will no doubt further reduce the density of ryegrass in 1975 but eradication is unlikely. The value of burning in destroying …

Pasture Species Investigations - Wheat Belt (May, 1975), N. R. Mckeown

Experimental Summaries - Plant Research

Results from trials comparing the growth and persistence of a number of annual pasture legumes are presented in this report. Rainfall conditions during the year are described briefly and a table of annual and growing season rainfall at relevant centres is appended. The experiments are grouped as follows according to average annual rainfall:- Zone A - Average annual rainfall > 400 mm Zone B - Average annual rainfall 345 - 400 mm Zone C - Average annual rainfall < 345 mm and then, further, on soil type. District Rainfall, 1974. 71LG16,, 72LG3, 74KA3, 70OTS2, 72TS5, 70NA3, 71TS22, 74NO3, 70ME4. The early break, with good rainfall continuing through most of the growing season, provided optimal conditions for most wheat belt trials. These conditions were in direct contrast to the dry years of the late 1960's and early 1970's. In 1974, legume growth on droughty deep sands should have been at its best. Serradella responded at Kukerin in direct relationship with earlier heavy dressings of potash. West of Three Springs, serradella and Tornafield medic stayed a little ahead of Harbinger medic and well ahead of Daliak sub. clover and rose clover. On deep sands at Marchagee and Arrino, subterranean clover was the only species worth considering. The failure of Eragrostis curvula to persist through the dry 1973-74 summer after good germination in late winter, indicates a need for more work on the establishment of this grass on deep sands. The low yields of dry matter at Tincurrin do not offer much incentive for such work, but Eragrostis, lupins and serradella probably give the best chance of pasturing the grossly infertile, erodable sands. Under favourable conditions, Geraldton sub. clover continued to show its versatility and aggressiveness. On an alkaline loamy sand at Lake King, waterlogged for periods during the winter, Dwalganup, Geraldton and Northam A produced more dry matter than a wide range of other pasture legumes. At Walgoolan, Geraldton maintained better than 503 content in mixtures with other sub. clover cultivars sown in 1970, while in a trial at Marchagee there was evidence of gradual, aggressive regeneration of Geraldton from a sparse pasture sown before the trial. Only two new legume species trials were planted in 1974, and these were not successful. Trial 74KA3, east of Katanning, demonstrated the need for timely planting. Had seed been available on time, the trial would have been planted before the onset of heavy rains and would have given better results. The failure of Tornafield and Harbinger on 74N03 should not weight the record unduly against these medics; :they have never excelled on clay loams, and they were sorely harassed by redlegged earthmite. The medics will not be replanted, but Northam A and Geraldton will be observed in 1975. :
