The Relationship Of Locus Of Control Of The Diabetic Patient And Compliance With Medical Regimen, Lois Daniel

Loma Linda University Electronic Theses, Dissertations & Projects

The literature indicates that many diabetic patients do not adhere to their prescribed medical regimen and that there is a need to discover factors that stimulate compliant behavior. It has been proposed that the patient's decision to accept or reject treatment has many determinants. This study explored the effect of one such determinant, the locus of control (the source of the stimulus for a person's behavior). It was hypothesized that a person with an internal locus (one who believes his actions influence his future) would be more likely to comply with a medical regimen than one with an external locus …

Summary Of Trial Results - 1974, N R. Mckeown

Experimental Summaries - Plant Research

Observations and measurements were made on 10 grazing trials and 11 small-plot legume species trials in 1974. Three of the grazing trials were under crop, two of them concluding low oestrogen species trials which had been grazed since 1969, and one of them, 68M023, West Moora, as an interval between pasture phases. The small-plot trials dated from 1970 or later and on most of them half of each plot could be grazed by sheep and half was protected. These trials have continued to supply useful information on the suitabiliy of cultivars to soil and climate and will be the subject …

Piericiden A Sensitivity, Site 1 Phosphorylation, And Reduced Nicotinamide Adenine Dinucleotide Dehydrogenase During Iron-Limited Growth Of Candida Utilis, John G. Cobley, T. P. Singer, H. Beinert, S. Grossman

Chemistry Faculty Publications

It has been reported that cells of Candida utilis, grown in continuous culture under iron-limited conditions, develop site 1 phosphorylation, without the appearance of piericidin sensitivity and without changes in the iron-sulfur centers of NADH dehydrogenase, on aeration in the presence of cycloheximide, as well as on increasing the supply of iron during growth. These findings were reinvestigated in the present study. The parameters and properties followed during these transitions were sensitivity of NADH oxidation to piericidin, presence or absence of coupling site 1, EPR signals appearing on reduction with NADH or dithionite, the specific activities of NADH oxidase, NADH-ferricyanide …

Response Of Nuclear Emulsions To Ionizing Radiations, Robert Katz, F. E. Pinkerton

Robert Katz Publications

Heavy ion tracks in Ilford K-2 emulsion are simulated with a computer program that makes use of the delta-ray theory of track structure, and the special assumption that the response of the emulsion to gamma-rays is 8-or-more hit. The Ilford K-series of nuclear emulsions is produced from a parent stock called K.0 emulsion, sensitized to become K.1 to K.5, and desensitized to become K–1 to K–3. Our simulations demonstrate that the emulsions K.5 through K.0 to K-1 are 1-or-more hit detectors, while K-2 is an 8-or-more hit detector. We have no data for K-3 emulsion. It would appear that emulsions …

Rates Of Water Entry Into The Subsoil Of Several Soil Series In Nebraska, David T. Lewis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Rates of water entry were measured for 11 soil series representing many of the soils in parts of Nebraska where urban growth is most intensive. The wetting procedure in making the tests is critical and a 24 hour wetting time as usually recommended is not adequate for all soils if the percolation test is made during a dry season. Rates of water entry differed among soils even though a large amount of variation was evident within the same soil series. Statistical analysis showed a highly significant negative relationship between both clay content and bulk density and rates of water entry. …

Summary Of 1975 Field Experiments With Advisers: "Rape Blackleg Disease Fungicide Trials", M J. Barbetti

Experimental Summaries - Plant Research

During 1973 and 1974 a large range of fungicide spray and seed treatment schedules were tested. The 1973 results were, on the whole, not very encouraging, but the very early post-germination spray, two weeks after germination, did indicate a possible means of control. In view of the 1973 results, in the 1974 trials fungicidal sprays were applied early, and a new method of application of fungicide to the seed, known as "prilling" was used. Using fungicide seed prills and seedless fungicide prills the idea was to have the fungicide mixed with materials which dispersed upon wetting, so releasing and making …

Journal of the Department of Agriculture, Western Australia, Series 4

The Department of Agriculture's Annual Report for the year ended June 30, 1975, took the form of short reviews of selected activities of the Department during the year.

A Field Technique Measuring Virus Decay And Potential Aerosol Hazard From Wastewater Sprinkler Irrigation, Michael F. Torpy, Robert A. Gearheart, J. Clifton Spendlove, Rex S. Spendlove

Reports

The increased use of domestic wastewater for irrigation purposes has stimulated a growing practice of sprinkler irrigating from oxidation ponds and other domestic wastewaters. Aerosols generated from these sprinkler irrigation systems may contain potentially hazardous pathogens. Subsequently, the aerosols can contain infective viruses which can be carried through the air to surrounding populations. Thus, a public health hazard can be created by sprinkler irrigating domestic wastewater. This study is an investigation of a means by which the virus decay rate of viruses in aerosols and the potentials hazard of sprinkler irrigation aerosol clouds may be examined. A means of injection …

Nutrient Dynamics And Gas Production In Aquatic Ecosystems: The Effects And Utilization Of Mercury And Nitrogen In Sediment-Water Microcosms, D. B. Porcella, V. D. Adams, P. A. Cowan, S. Austrheim-Smith, W F. Holmes, J. Hill Iv, W. J. Grenney, E. J. Middlebrooks

Reports

Sixteen sediment-water microcosms designed to allow complete gas, liquid, and solid mass balances of gases, nutrients, and mercury were studies under dark conditions or varying light intensity for a period of 189 days. Results indicated that the microcosm technique is a very sensitive method of analyzing microbial dynamics in sediment water systems. Gas quantity and composition changes were easy to monitor and were especially sensitive to light and nutrient variations. Nitrogen fixation occurred in all lighted systems (blue-green algae nitrogen fixers, Anabaena, and others) and was adequate to insure that no nitrogen limitation occurred even though nitrogen limitation was imposed …

Impacts Of Energy Development On Utah Water Resources, Barry C. Saunders

Reports

Introduction: Choosing a theme for a conference especially one for a group of diverse disciplines such as the American Water Resources Association encompasses, is always a challenge. you find yourself torn between thigns you'd really like to talk and hear about, and topics you think will draw attendance. It was most fortunate when somebody came up with the idea of Water for Energy, becasue to my way of thinking, it met both of these ends. There is no denying that starting in late 1973, energy has been the catchword, and the energy crisis has been the bandwagon to leap upon. …

Effect Of Feedlots On Water Quality, Ronald D. Cheetham, Alan J. Holmes, David Borresen

Journal of the Minnesota Academy of Science

The effect of feedlot runoff on water quality was examined. Samples were collected from river feedlots and offshore from lake feedlots and compared with samples from appropriate control sites. Bacterial contamination, as measured by the total coliform test over two successive summers, exhibited significant variation between feedlot and control sites. Coliform levels at lake sites adjacent to feedlots were double the levels at control sites; while in river systems average coliform levels downstream from feedlots were approximately 17 times the upstream controls.

Mixing Effects On Shallow Water Bodies, Kim Robin Powell

Retrospective Theses and Dissertations

This report is intended to examine the ecological changes due to mixing in shallow water bodies. Physical, chemical, and biological changes are reported in literature. A literature search revealed the range of mixing nodes or processes. Assessment of ecological changes due to mixing by boating activities had been evaluated in a research project supported by the environmental Protection Agency and conducted at Florida Technological University. The examination of changes due to mechanical mixing on lake ecology simulated in fifty-five gallon drums indicated the sensitivity of such parameters as total Kjeldahl nitrogen, conductivity, pH, temperature, and dissolved oxygen. Problems of reproducibility …
