Forage Production From Shrubs On Saline Land, C V. Malcolm

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

In the first volume of the Journal of the Department of Agriculture in the year 1900, the results of experiments at Tulare Experiment Station in California on the growing of Australian saltbushes are reported.

Seed was first sent from Australia by Baron von Mueller in June, 1881. Three species of saltbush (A. semibaccata, A. numularia and A. vesicaria) are all reported to have grown well.

Although C. A. Gardner in 1929 suggested the growing of saltbushes for forage, the earliest and clearest recommendations are those of Teakle and Burvill in 1945.

Early research tended to concentrate mainly on the possibility …

Pesticide Effects In A Simulated Soil Ecosystem, Raymond J. Samp

Masters Theses

The screening of pesticides to determine which were most inhibitory to bacteria was accomplished by testing the effects of 10 pesticides on 9 different organisms using the disk assay method. Results showed that Gram positive bacteria were more sensitive to all pesticides tested than were the Gram negative bacteria. In addition, the hormone herbicides were found to be the most inhibitory to these bacteria and 2,4-D (2,4-dichlorophenoxyacetic acid), a hormone herbicide, was chosen for subsequent in vivo studies.

A soil perfusion apparatus was used to determine the effects of 2,4-D in a typical soil ecosystem. Bacterial plate counts and nutrient …

The Water Quality And Benthic Macroinvertebrate Fauna Of Lake Charleston, Coles County, Illinois, Paul Barding

Masters Theses

The benthic macroinvertebrate fauna and 15 water quality parameters for five sites on Lake Charleston, Coles County, Illinois were examined for 26 weeks from March 14 through September 5, 1974. None of the water quality parameters studied showed sufficient deviations at any particular area on the lake to merit demarcated water quality zonation. The lake, with its continuous mixing and shallow depth, represented a fairly stable and continuous environment. The benthic macroinvertebrate fauna was determined as fairly diverse and some indication of seasonal variation was apparent. No significant compositional variation over different areas of the lake was found, also indicating …

The Two-Way Mixed Model Analysis Of Variance, Kenneth Davis Buckley

Theses and Dissertations

The analysis of variance for experiments where the fixed effects or random effects model is appropriate is generally agreed upon with regard to testing procedures and covariance structure. It is only in experiments involving both random and fixed factors, i.e. mixed effects models, that controversy occurs as to the proper analysis. The mixed effect model has been considered by many statisticians, and several techniques have been developed for explaining its structure and performing its analysis for balanced data sets. The relationship of these techniques have been discussed in several papers as well.

The simplest case of the difficulties presented by …

Electrical Alternans In Cardiac Tamponade, Andreas P. Niarchos

Henry Ford Hospital Medical Journal

Of nine patients with pericardial effusion due to various causes, four developed cardiac tamponade. Electrical alternans was present In all four, being total in three, and ventricular in one. From the diagnostic point of view, the alternans corresponded with the clinical diagnosis of cardiac tamponade and the radiological signs of a large pericardial effusion. The pericardial fluid was hemorrhagic in three patients and transudate (hydropericardium) in the fourth. In two patients alternans was present with heart rates below 100 per minute. Apart from the exact (1:1) type of electrical alternans, three new types are described; a 2:1, 3:1 and a …

Rotationally Inelastic Molecular Scattering. Computational Tests Of Some Simple Solutions Of The Strong Coupling Problem, Thomas P. Tsien, Gregory A. Parker, Russell T. Pack

Faculty Publications

Partial cross sections (opacity functions) for rotational transitions in atom-diatom collisions are computed in the infinite-order sudden (IOS) approximation and compared with accurate close-coupling (CC) calculations. Agreement is good in the dominant coupling (small total angular momentum J) region. Simple methods for calculating integral inelastic cross sections are discussed, and it is found that accurate cross sections can often be computed very simply, even when large numbers of channels are coupled together, by using IOS or first-order sudden (FOS) approximations for small J and CC or exponential Born (EBDW) methods for large J.

Systematics And Evolutionary Relationships Of Spiny Pocket Mice, Genus Liomys, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Introduction

Spiny pocket mice of the genus Liomys are members of the rodent family Heteromyidae and together with the genus Heteromys form the subfamily Heteromyinae. Their geographic range extends from northern Sonora, in western Mexico, and southern Texas southward to the vicinity of the Panama Canal Zone. Within this area, members of the genus occur mainly in dry to arid situations being replaced in areas of rain forest and cloud forest by members of the genus Heteromys. The vernacular name for Liomys is based on the fact that many of their hairs have been modified in the form of …

A Study Of Water-Soluble Inhibitory Compounds (Algicides) Produced By Fresh-Water Algae, Denny O. Harris, Manhar C. Parekh

KWRRI Research Reports

A complex system of growth inhibitors was observed in the green algae (Volvocaceae). Inhibitors were found in the culture filtrates of some genera which limit their own growth (autoinhibitors) while others in the family produce substances which check the growth of other genera (heteroinhibitors). These inhibitors were destroyed by autoclaving. It was decided that Pandorina morum, which produced the strongest inhibitor and Volvox tertius, the most sensitive to the inhibitor would make an excellent model system for a study of the chemical and physical properties of these naturally occurring algicides. The algicide could be removed from actively growing cultures about …

KWRRI Research Reports

Samples of water, bottom fauna, and fishes were collected from 66 stations in the Salt River and one of its principal tributaries, the Beech Fork and its tributary, the Chaplin River, Kentucky. Precipitation ranged from 38.86 inches (1969) to 58.04 inches (1970), an increase of nearly 50 percent with marked fluctuations in discharge. Intensive comparisons of phosphates, sulfates, specific conductance, total alkalinity, total hardness, and turbidity showed the streams to be relatively clean and healthy. Nearly 300 different kinds of benthic organisms and other macroinvertebrates have been collected and identified from the basin. Detailed studies of caddisflies and stream drift …

A Test Of The Simple Recessive Hypothesis For The Inability To Taste Phenyl-Thio-Urea: A Family Study, Susan I. Wolf

Dissertations and Theses

This thesis is a report on the analysis of family data gathered to test the simple recessive hypothesis for the inability to taste phenyl-thio-urea (P.T.C.). The simple recessive hypothesis states that the inability of a minority of persons to taste high concentrations of P.T.C. is due to the action of an autosomal recessive gene in the homozygous condition.

Enzyme And Tissue Alterations In Fishes: A Measure Of Water Quality, David E. Hinton, M. W. Kendall, J. C. Koenig

KWRRI Research Reports

A variety of freshwater fishes were studied by light and electron microscopy, enzyme histochemical and biochemical methods, The objective was to determine normal structure and function in specific target organs and to compare these to altered states in aquatic pollution. The basic question, "can fish tissues and enzymes serve as indicators of water quality?," was asked. Microscopic alteration in gill was indicative of copper toxicity at an exposure of 20 parts per billion, Gross and light microscopic alterations were indicative of a single exposure of channel catfish to 15 parts per million of methyl mercuric chloride (CH₃HgCl). Microscopic …

A Simulation Model Of Peromyscus Leucopus In An Area Of The Great Dismal Swamp, James E. Paschal Jr.

Biological Sciences Theses & Dissertations

A computer simulation model was developed to explain the population dynamics of the white-footed mouse (Peromyscus leucopus) in an area of the Great Dismal Swamp. The model was designed to provide an experimental base for future studies. The model indicates relationships between food availability, home range size, competition with Peromyscus nuttali habitat selection and reproduction.

White-footed mice were trapped in the Old Dismal Town site during each season from April, 1972 through March, 1973. The age-sex structure of the population was determined, and was compared with the simulated structure. Although there were significant discrepancies between the comparisons, the …
