Water Economy For Lawns And Gardens, K S. Cole

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

Much of the summer water consumption occurs because it is widely believed that heavy summer watering is necessary. Householders often mistakenly water heavily to keep their gardens green and growing. Many may not realise that gardens can be kept vigorous and healthy with much less water than is commonly applied.

Nitrogen Fertilisers For Pasture Production, Walter Jacob Cox, K Hawley

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

At current prices nitrogen fertiliser is not an economic substitute for good clover pastures, but it can supplement the system by increasing nitrogen supply at peak growth periods. It can also provide useful increases in pasture production at critical feed times. Nitrogen usage for pasture production is still in the experimental stages and small areas should be tried before large-scale application.

Double Reflection Dips - From Grating Ruled Semiconductors, Le-Fu Teng

Doctoral Dissertations

"The double dips, previously observed by Fischer, Anderson, et al., which appeared in the reflection spectra of grating surfaces on the Te-doped semiconductors GaAs and InSb around the plasmon and phonon frequencies have been measured in more detail. In the plasmon region, several possible explanations of the phenomenon are discussed. A simple equation checked with the rigorous theory is proposed and is shown to fit the data well. In the phonon region, the extra dip is calculated and identified as being caused by surface phonons"--Abstract, page ii.

Surface Electromagnetic Waves With Damping I. Isotropic Media Ii. Anisotropic Media, Gary Shannon Kovener

Doctoral Dissertations

Paper 1: “Surface electromagnetic wave (SEW) dispersion curves are usually calculated using a simple equation derived from Maxwell’s equations and boundary conditions. When complex dielectric functions are used for the two media, the component of the propagation vector along the surface k_x becomes infinite as the frequency ω approaches the surface polariton frequency ω_s if ω is considered complex and k_x real. On the other hand, if k_x is considered complex and ω real, the dispersion curves bend back toward smaller k_x as ω approaches ω_s. We have previously demonstrated that both types …

Base-Induced Reactions Of P-Nitrobenzyl Compounds, Paul Henry Ruehle

Doctoral Dissertations

"The base-induced reactions of several p-nitrobenzyl compounds were studied. The products varied with changes in the leaving groups. With relatively poor leaving groups (Cl, S⁺(Me)₂), p,p'- dinitrostilbene was produced in good yield. The products of the reaction of p-nitrobenzyl chloride and hydroxide ion in 50% aqueous dioxane were 52.0% p,p'-dinitrostilbene, 43.9% cis- and trans-p,p'-dinitrostilbene oxides, 3.2% p-nitrobenzyl alcohol, and traces of other compounds. With dissolved oxygen, no stilbene was produced; the main product was 88% cis- and trans-p,p'-dinitrostilbene oxides. The addition of small amounts of di-t-butyl nitroxide caused a decrease in both the rate of the reaction and the amount …

Unity In The Theory Of Elementary Particles Through Group Theory, Douglas Karl Lemon

Undergraduate Honors Capstone Projects

Science is the process of seeking unity in the diversity of natural phenomenon. The purpose of this paper is to demonstrate that group theory brings unity to the theory of elementary particles. The prime motivations are first, to find a quantitative representation of the Lorentz transformation, and second, to find a quantitative representation of angular momentum. Since both of these have continuous parameters, groups with continuous parameters, particularly Lie groups, are of interest.

The first portion of the paper develops the definition of Lie groups and their associated Lie algebras. The prerequisite definitions of transformations, groups, group representations, and continuous …

A Study On Two Iodine Containing Peptides Isolated From Porcine Thyroglobulin, Frederick E. Bishop Jr.

Masters Theses

"Two iodopeptides were isolated from thyroglobulin that had been digested with trypsin by paper electrophoresis and paper chromatography. The amino acid analysis demonstrated that the amino acid compositions were similar. The N-terminal amino acid of both iodopeptides was shown to be leucine. The amino acid sequence of one of the iodopeptides was determined by the Edman degradation method and digestion with the enzyme Carboxypeptidase A. The sequence was shown to be: NH₂-Leu-Asn-Ala-Ser-Glu-MIT-Gly-Thr-Ser-Gly-COOH. Other workers have shown that synthetic tyrosyl peptides with the sequence Glu-Tyr are iodinated by the thyroid peroxidase enzyme with a greater specificity than other tyrosyl peptides. This …

Influence Of Vegetation On The Distribution Of Small Mammals On A Waterfowl Production Area, Douglas A. Searls

Electronic Theses and Dissertations

. A study was conducted on a Waterfowl Production Area in Brookings County, South Dakota in 1972-73 to determine the distribution and abundance of small mammals. Three cover types, reseeded native grassed, brome-alfalfa, and bluegrass, were studied. Meadow voles (Microtus pennsylvanious), and deer mice (Peronyscus maniculatus) were captured most frequently. Jumping ice (Zapus hudsonius), masked shrews (Sorex cinerius), short tailed shrews (Blarins brevicauda), grasshopper mice (Omychomys leucogaster) and house mice (Mis musculus) were also taken. The bluegrass association had the highest number of small mammal captures and the reseeded native grass association has the least. There was no significant difference …

Pheasant Reproduction And Survival As Related To Agricultural Fertilizer Use, Lawrence Francis Fredrickson

Electronic Theses and Dissertations

Wing-clipped wild pheasants (Phasianus colchicus) were stocked in 1-acre and 0.5-acre pens having oat and bromegrass cover in 1972 and 1973 to test effects of fertilizer (Formulations: 34-0-0, 18-46-0, 0-46- 0, and 0-0-60) on pheasant reproduction and survival. One-half of the pens were fertilized with the recommended rate of pelleted fertilizer and the other half without fertilizer. Complete nest searches in July showed that nesting success was not significantly different (P>0.05) between treatments for both years. No significant difference (P>0.05) was found in clutch size or in number of ovulated follicles from control and experimental hens. Significantly more …

Three groups of nine pelicans each were studied: a polychlorinated biphenyl (PCE) treated group, a DDT, DDD, DDE treated group, and a Control group. The object of this study was to determine the effect of PCB and DDT, DDD, DDE on the learning ability of penned white pelicans. Control, PCB, and DDT groups of penned white pelicans learned to …

Heavy Metal Concentrations In The Clam Rangia Cuneata From The Rappahannock And James Rivers, Robert Emile Croonenberghs

Dissertations, Theses, and Masters Projects

This project investigated the feasibility of using the brackish water clam Rangia cuneata as a heavy metal pollution indicator, and further investigated the state of heavy metal pollution in the James River. Rangia cuneata were sampled in the fall of 1972 from the Rappahannock and James Rivers , and meats were analyzed by atomic absorption spectrophotometry for wet weight concentrations of copper, zinc, cadmium and lead. Levels of copper and zinc in Rangia cuneata were shown to be unaffected by clam size, spawning differences, salinity or distance upriver, and substrate grain size. Heavy metal concentrations in the oxidized channel sediments, …

Benthic Infaunal Community Formation In Dredged Areas In Hampton Roads, Virginia, Thomas Karl Duncan

Dissertations, Theses, and Masters Projects

The macrobenthic fauna in three dredged areas in Hampton Roads, Virginia was sampled for 14 months. Repopulation occurred very rapidly after the cessation of dredging, but the dominant species were generally not those previously recorded as mud-bottom dominants in the Hampton Roads area. The faunal changes through time somewhat agreed with those reported in classical successional sequences. This dissertation is from the Joint Program Degree from the College of William & Mary and University of Virginia and awarded by the University of Virginia.

A Study Of The Kinetic And Thermodynamic Properties Of Carbon Acids In Methanol, Dennis L. Filger

Doctoral Dissertations

The thermodynamic acidity (pK_a) of iodoform in methanol was determined at 25°C and 35°C; the values are 18.74 and 18.05, respectively . These acidity constants were determined by a modification of the equilibrium quenching technique which involves the conversion of the conjugate base of iodoform, present at equilibrium, to the radioactively labelled acid.

The rate constants for the methoxide-catalyzed hydrogentritium exchange of chloroform, iodoform, 9-phenylfluorene and indene were determined in methanol at various temperatures. The second-order rate constants obtained from these studies were shown to be the rate constants for removal of a triton. The activation parameters (ΔH …
