On The Use Of Tris (Hydroxymethyl) Aminomethane As A Diluent In Quantitative Analyses Of Soil Bacteria, Barry L. Keller

Masters Theses

Introduction

Many investigations have been conducted in the field of soil microbiology during the past.six decades. Most notable among the contributors is S. A. Waksman whose voluminous works have established many of the procedures used in microbial analyses of soil. Yet, the one fact that is foremost to any reviewer of the literature covering this field is that no standardization of techniques for soil analyses exists. The following presentation deals with one method used to estimate the number of bacteria and actinomycetes in soil.

The use of Tris(hydroxymethyl)aminomethane (hereafter referred to as "Tris") is not new. Tris currently is used …

The Archeology Of The Lime Creek Site In Southwestern Nebraska, E. Mott Davis

University of Nebraska State Museum: Staff and Affiliates, Publications

The Lime Creek site is a stratified Early Lithic (Paleo-Indian) camp site buried in the Terrace-2A alluvial fill of a valley in the dissected loess plains. Geological correlations indicate an early Valders (Wisconsin- IV) date. A radiocarbon date (No. C-471) of 9524 B.P. from just below Lime Creek I, the lowest occupation zone, must be taken only as a minimal possible age for the site. The animal bones in Lime Creek I are primarily of pronghorn and beaver, whereas those in Lime Creek III, the highest occupation zone, are exclusively of bison. The change in hunting patterns seems due to …

Some Effects Of Ph, Temperature And Light On The Production Of Zoosporagia In Saprolegnia Parasitica Coker, Philip C. Lee

Master's Theses

Pure cultures of Saprolegnia parasitica Coker were grown under varied conditions of temperature, pH, and light conditions. In liquid medium colonies were spherical with a zonal effect in the distribution of zoosporangia.

Near the limiting extremes of pH and temperature, beaded hyphal tips were found in place of normal sporangia. Teorell Universal buffer in the sporulation water inhibited production of sporangia. The pH minimum was 4.0 - 4.1, optimum 6.3 - 7.4, and maximum 8.o - 8.3. The maximum number of sporangia was produced at 15 C. Between 3.4 and 5 C , a delay in sporulation was noted and …

Texas And Technology, Martin Goland

Journal of the Graduate Research Center

It is a pleasure to have this opportunity to talk with you about the Texas scene and its stake in science and technology. The force of science in modern society is a compelling one, reaching into virtually every aspect of our lives, and the future health of our state and our nation hinges in large measure on the extent to which we plan wisely to have technology serve our ends, rather than control our destiny.

Notes On The History And Philosophy Of Science: 2. Barker On Simplicity In Historical Geology, Peter W. Bretsky Jr.

Journal of the Graduate Research Center

In the literature of the philosophy of science the principle of simplicity is usually analyzed by reference to examples taken from mathematics and the abstract physical sciences. Thus Mario Bunge, in the Panel Discussion of Simplicity of Scientific Theories, which was conducted at the 1960 meetings of the American Association for the Advancement of Science in New York City, chose four of his six basic examples from physics and astrophysics. These were the Copernican and Ptolemaic theories, the gravitational theory of Einstein and others, the beta-decay theory, and Newton's and Hamilton's formulation of dynamics. At this same symposium, however, Stephen …

Interbasin Movement Of Ground Water At The Nevada Test Site, Isaac J. Winograd

Publications (WR)

The present paper presents hydraulic evidence for the interbasin circulation of ground water through carbonate rocks of Paleozoic age at the Nevada Test Site. An integral part of this evidence is the discovery that aquifers in alluvium and tuff, formerly thought to be the principal aquifers at the Test Site, are semiperched above a thick tuffaceous aquiclude that separates them from the carbonate rocks.

This paper is based on one of the studies being made by the Geological
/="/">Survey for the Atomic Energy Commission. These studies seek to evaluate
/="/">the risk that may arise if ground water should …

The Gascoyne River Catchment Area, W M. Nunn

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

A RECENT Department of Agriculture survey of the Gascoyne River catchment area has indicated that deterioration of plant cover in the area contributes to the severity of floods which regularly damage the town of Carnarvon.

It is hoped that the results of the survey will help efforts to regenerate the catchment area, and reduce the risk of flooding.

The Inactivation Of Neurohypophyseal Hormones By The Toad Bladder, Arthur Karlin

Student Theses and Dissertations

The urinary bladder of the toad, Bufo marinus, was homogenized and the particle-free supernatant fraction prepared. Incubation of this fraction with the hormones, oxytocin, arginine vasopressin, lysine vasopressin, and oxytocin ring amide caused their inactivation. The decrease in hormone activity was roughly exponential with the time of incubation. The hormone inactivating activity of the supernatant fraction was decreased by treatment with N-ethylmaleimide, by heating to 50° C for 5 minutes, and by cold storage at -20° C. The decrease in activity due to cold storage, but not that due to either of the other two treatments, was reversed by the …

Cobalt : Its Use To Control Wasting Disease, Laurence C. Snook

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

FOR many years it was assumed that in Western Australia cobalt deficient areas were restricted to a coastal fringe which rarely extended more than 20 miles inland.

This has proved a costly false assumption. During recent years cobalt deficiency has been diagnosed over extensive areas of inland country.
