Part I - Controlling The Soil Moisture Environment Of Transpiring Plants, Part Ii - Prediction Of Leaf Temperature Under Natural Atmospheric Conditions, Charles T. Haan, Billy J. Barfield, Robert Edling

KWRRI Research Reports

Part I

A technique for controlling the soil moisture potential in the root zone of transpiring plants was developed. The method uses the principles of unsaturated flow through a porous media to develop the desired moisture potential. In the case of non-steady state transpiration, the maximum possible fluctuation in the soil moisture potential can be determined by the techniques presented.

Part II

Two implicit leaf temperature prediction equations were derived from the energy balance approach. The equations define sensible and latent heat transfer from a plant population as a two step process:

1. Transfer between the plant leaf and the canopy …

The Enterobacteriaceae: A Preliminary Study Of New Methods Of Identification: Rapid Biochemical Testing And Salt Tolerance, William F. Brooks Jr.

MUSC Theses and Dissertations

Commercially available reagent-impregnated paper strip tests and tablet substrate tests were evaluated in comparison to the standard biochemical tests using representative members of the Enterobacteriaceae. For the most part, these tests were found to be unreliable or difficult to interpret. Standard media for key biochemical tests were then modified and a new inoculation procedure developed to allow for test results after four hours incubation. Representative members of the Enterobacteriaceae were tested using the modified standard media and, where a given test was critical for the differentiation of the organisms, the rapid test results were in complete agreement with the control …

Screening Of Chemosterilants Against The Southern House Mosquito Culex Pipiens Quinquefasciatus, M. D. Boston, R. S. Patterson, C. S. Lofgren

Entomology Papers from Other Sources

In view of the current interest in the use of sterile males to control or eradicate some species of mosquitoes, information is needed about chemicals or other methods that induce sterility in these insects. Thus, at the Insects Affecting Man Investigations Laboratory at Gainesville, Fla., we have begun to evaluate the sterilizing effect of chemicals on the southern house mosquito, Culex pipiens quinquefasciatus Say.

Identification Of Seeds Of Undesirable Weeds, J R. Peirce

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

PREVENTING the introduction of weeds to a farm is a far cheaper proposition compared to the expensive and laborious process of eradicating a well established infestation.

Unfortunately most weeds establish themselves as plants before they are identified, the main reason being farmers are often unable to recognise weeds in the seed stage.

The Effectiveness Of Camphorated Paramonochlorophenol, Metacresyl Acetate, And Prednisolone In Combination As An Antimicrobial Agent, Maurice Cutler

Loma Linda University Electronic Theses, Dissertations & Projects

Post-treatment discomfort following endodontic procedures can be caused by inflammation due to injudicious use of intracanal medicaments. Camphorated paramonochlorophenol, metacresyl acetate, and prednisolone in combination is advocated to reduce the inflammatory potential of the germicide and thus reduce the occurrence of post-operative pain. It is imperative that a medicament retain antimicrobial activity while reducing inflammatory potential.

This investigation was undertaken toward determining on an in vitro quantitative bactericidal versus bacteriostatic basis by use of the broth dilution test tube method whether camphorated paramonochlorophenol, metacresyl acetate, and prednisolone in combination retains antimicrobial activity comparable to selected other commonly used nonspecific germicides. …

The Effect Of Gamma Irradiation On Growth Of Seven Strains Of Trypanosoma Avium, Roy Wesley Leid Jr.

All Master's Theses

The prime motivating factor in the present study was the desire to show significant differences in radio-sensitivities within six strains of Trypanosoma avium. A seventh strain was later added for the last two irradiation treatments. Gross morphology and differences in growth curves associated with varying temperatures suggested that the strains being cultured were not the same. With these differences in mind, the strains were subjected to different dosage levels of gamma irradiation.

Observations On The Effects Of Aspirin On Cells In Vitro, Roger Scott Barron

University of the Pacific Theses and Dissertations

Numerous reports concerned with the effects of chemical agents (drugs) on animals, especially humans, have appeared in the literature over a period of centuries. Until very recently, however, the observations on which these reports were based have been rather general. The salicylates, for example, have been used and studied for many years yet investigations into their specific effects within living cells are minimal.

Of the several members of the salicylate group, the two that have gained widespread use in clinical practice are sodium salicylate and acetylsalicylic acid, commonly known as aspirin, the name of which was derived from the contraction …

Studies On An Antibiotic-Producing Strain Of Bacillus Megaterium X, Kishori Madhukar Chaubal

University of the Pacific Theses and Dissertations

On July 10, 1968, while observing the effects of ultra-violet light on a plate culture of Sarcino lutea, o contaminant was found growing in the form of a colony surrounded by a clear zone of inhibition where S. lutea had failed to grow. A smear from this contaminant colony was found to contain a Gram positive, chain-ond spore-forming bacillus. The organism was isolated and its antagonism against S. lutea was reshocked. Preliminary investigation of its activity against other bacteria indicated that this activity was directed against 5. lutea only. I was decided to continue the investigations with two aims in …

A Myological And Osteological Comparison Of The Pelvic Appendage Of The Male And Female Western Meadowlark, Thomas Felix Sourisseau Jr.

University of the Pacific Theses and Dissertations

Sexual dimorphism has been noted to exist in many genera of birds, but it is not until recently that papers have appeared which deal with the actual extent of sexual dimorphism and its possible adaptive significance. The papers of Rand (1952), Sibley (1957), Amadon (1959), and Selander (1966) hypothesize about the possible significance of sexual dimorphism in birds, and the papers of Kilham (1965), Selander (1965), Storer (1966), Ligon(1968), Ingolfsson (1969), and Verner and Willson (1969) examine the relationship between hypotheses on the significance of sexual dimorphism and actual field conditions. None of these papers deals with differences in bone …

Alcaptonuria And Ochronosis With Diabetes Mellitus And Mycosis Fungoides: A Case Report, Jamshed U. Haq, Roy B. Patton

Henry Ford Hospital Medical Journal

A Negro woman with alcaptonuria, ochronosis, ochronotic arthropathy, diabetes mellitus and mycosis fungoides died of acute renal failure due to diabetic glomerulonephropathy and ochronotic nephrosis. The role of the renal lesions of ochronosis is presented in potentiating the effect of an underlying renal disease producing rapidly progressive kidney failure. The occurrence of ochronosis, diabetes mellitus and mycosis fungoides is apparently coincidental only. Special stains of tissue sections confirm the similarity of melanin and ochronotlc pigment.

Fisheries Report No V (5) - Report On Marron In Farm Dams (Cherax Tenuimanus), N M. Morrissy

Fisheries Research Reports

A programme of selling marron (Cherax tenuimanus) to country dwellers for stocking farm dams, has been carried out by the Pemberton Trout Board for the past few years with considerable financial gain. In this case permission to sell the marron was granted by the Department of Fisheries and Fauna so as to encourage the provision of stocks of this large, freshwater crustacean for farmers in the dryer inland areas of the Southwest which are remote from sources of fresh fish and from natural stocks of marron.

The marron, however, have been sold indiscriminately, upon request, without any advice as to …

Cation Transport I. Metabolic Activity Of The Polyphosphoinositide Complex In Isolated Renal Cortex Tubules, Paul Bartlett, James F. Bossart

Henry Ford Hospital Medical Journal

Although several mechanisms have been proposed to explain the transport of hydrophylilc cations across lipoprotein barriers, the nature and identity of the carrier mechanism have not yet been elucidated. The present communication is concerned with a mechanism postulating that monoesterified phosphate on the inositol moiety of phosphatidyl inositol might provide anionic sites that function as cation carriers via a phosphorylation-dephosphorylation cycle, catalyzed in its simplest sequence by phosphatidyl inositol kinase and diphosphoinositide phosphomonoesterase activities. In this context, one might reasonably expect that turnover of monoesterified phosphate in the polyphosphoinositides of isolated renal cortex tubules would be reduced in tubules in …

Aqueous Microbiology: The Possible Role Of Cell Wall Deficient Bacteria In Uveitis, Philip C. Hessburg, Lioa H. Mattman, Carolyn Barth, Lloyd T. Dutcheshen

Henry Ford Hospital Medical Journal

Samples of aqueous humor were obtained from the anterior chamber of patients with uveitis. Bacterial L-forms, or cell wall deficient forms, were recovered from 11 of 19 eyes with unexplained uveitis. These bacterial variants were cultured on newer, highly specialized media and stained with acridine orange. This stain demonstrates fluorescence of nucleic acids under UV microscopy.

Characterization Of Xanthomonas Phaseoli Bacteriophages, Anne K. Vidaver, Max L. Schuster

Department of Plant Pathology: Faculty Publications

Ten bacteriophages for Xanthomonas phaseoli were characterized. On the basis of adsorption rates, latent period and burst size, plaque morphology, host range, efficiency of plating, ultrastructure, sensitivity to osmotic shock, streptomycin sensitivity, temperature effects on plating efficiency, and serology, the phages were separated into at least three groups. Some of the phages were infectious for Pseudomonas phaseolicola (four strains) and P. syringae (one strain) in a narrow temperature range. The taxonomic and ecological significance of this finding is discussed.

The Effect Of Two Growth Retardant Chemicals, Cycocel And B-Nine, On Certain Nitrogeneous Components In Barley Seedlings, Linda Kinser

Masters Theses & Specialist Projects

Certain chemicals are known to inhibit growth in many plant species. These chemicals possess a common trait, the ability to inhibit stem elongation by suppressing the activity of the subapical meristematic region (11). These growth retardants have been extensively studied during the past several years in an effort to determine the biochemical mechanism responsible for reduction in plant height. The characteristic effect of these chemical retardants on the growth pattern has been described as producing plants with shorter, thicker stems and broader, darker green leaves. Tolbert, however, noted that although plants treated with the plant growth retardant, Cycocel, (2-chloroethyltrimethlammoniumchloride) and …

An Investigation Of A Mycorrhizal Association On Opuntia Polyacantha, R. Craig Stutz

Theses and Dissertations

Roots of Opuntia, polyacantha Haw. from Juab County, Utah were found to be nodulated. An anatomical study of the nodulated roots showed them to be ectotrophic mycorrhizae. Fusarium poae (Peck) Wollenweaver was found associated with the nodules both as an epiphyte and an endophyte. However, reinfection with this organism failed to induce subsequent nodulation. Under certain conditions the roots of o. polyacantha are able to overcome the mycorrhizal infection and elongate. It is not uncommon for several branch roots to originate from a single nodule. It is suggested that the fungus-root association found in o. polyacantha represents an early stage …

The Effects Of Herbicides On Three Soil Inhabiting Blue Green Algal Species, Lee C. Darlington

All Master's Theses

The object of this study was to examine the effects of varying concentrations of 2, 4-D, Dalapon, and Tordon on the growth of several nitrogen-fixing blue-green algal species obtained from soil samples and grown under culture conditions in the laboratory.

Ultrastructural Investigations Of Tilletia Caries Teliospores, James Vincent Allen

Theses and Dissertations

The purpose of this study was to investigate the ultrastructure of Tilletia caries teliospores. Specimens were prepared for viewing in the electron microscope by freeze-etching and thin-sectioning techniques. Thin-sectioning techniques gave excellent results with the teliospore walls and the lipid bodies within the teliospore but failed to adequately fix the membranes and internal organelle systems. Micrographs of Tilletia caries teliospores prepared using thin-sectioning show three major wall layers and two partition wall layers and abundant lipid bodies. The freeze-etch method of spore preparation proved superior to the thin-sectioning used in this study to reveal the internal organelle systems of the …

The Effect Of Chemical Adjuvants Of The Survival Of The Free-Living Stages Of The Gastrointestinal Nematode, Haemonchus Contortus, Anthony T. Chang

Theses and Dissertations

Considerable research has been done on the influence of various chemical adjuvants, such as glycerol and dimethyl sulfoxide (DMSO) on the survival of protozoan organisms. (Levine and Marquardt, 1955; Levine, Mizell and Houlahan, 1958; Levine, et al. 1962; Levine and Andersen, 1965, 1966; Fitzgerald and Levine 1957 1 1961; Diamond, 1964). Considerably less work has been done on metazoan parasites. The effects of various chemical adjuvants on the survival of Haemonchus contortus, the large stomach worm of sheep, at extremely low temperatures has not been reported. The purpose of this research was to determine if different concentrations of chemical adjuvants …
