Criteria For Recreation Site Selection On Flood Control Reservoirs-Case Studies, Kenneth B. Mclaughlin

Electronic Theses and Dissertations

Stephen F. Austin State University was awarded a contract in August 1971 to select the 1,200 acres best suited for recreation area development on three proposed flood control reservoirs. At that time, there was no central publication which could be used as a guide for such a project. This thesis was written to help correct this situation. The nine factors that were used in initial site selection are soils, topography, access, wind, vegetation, land ownership, distribution of the sites, bridges and open-water and cove locations. Once the sites were selected, they were evaluated and assigned priorities for development according to …

Morphological And Ecological Relationships Of Etheostoma Caeruleum And Etheostoma Spectabile In West Central Indiana, Dennis E. Clark

All-Inclusive List of Electronic Theses and Dissertations

Etheostoma caeruleum Storer and Jii. spectabile (Agassiz) are closely related members of the family Percidae, subfamily Percinae, tribe Etheostomatinae. This group, consisting mostly of small, brilliantly colored darters, has been partially characterized by Collett ( 1963). Several papers have been published dealing with the biology of these two species. One or both species have been described by Storer (1845), Agassiz (1854), Reeves (1907, but see Trautman, 1930), Trautman (1930, 1957) Knapp (unpublished Ph.D. dissertation), Distler (1968), and others. Trautman (1930, 1957) Gerking (1945), and Hubbs and Lagler (1947) reported that h caeruleum lives in larger and faster streams, whereas JL_ …

An Approach To Range Inventory For The Annual Range Type Of The Arid And Semi-Arid Regions Of The Sudan, Farid D. Iskander

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Range inventory, by definition, is the evaluation of the range resources to determine a proper and safe level of stocking and to provide a record of vegetation and vegetation changes (Stoddart and Smith, 1955). Range survey is defined by the Range Conservation Glossary, Soil Conservation Service (1944) as "a systematic and comprehensive inventory and analysis of the range resources and related management problems of a range area for the purpose of developing plans of management therefrom." Accordingly, range inventory is the quest for basic information about rangelands and the development of guides and procedures for their management, improvement and efficient …

A Linear Programming Decision Model For Elk And Deer Management On The Logan Peak Winter Range Area, Ronald P. Grove

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

One consequence of our surging human population is the corresponding increased level of resource consumption. This occurrence renders it imperative that resource managers intensify their management of the world's natural resources. Failure to improve management techniques involving the use of these resources will result in premature depletion of non-renewable commodities and severe checks on the vigor of renewable resources.

Management is faced with the difficult task of searching for astute means of allocating natural resources. Because of the tremendous size and complexity of the natural world, the problem can be extremely complicated.

Mathematical techniques have proved useful in providing natural …

How The Paper Industry And Its Associated Industries View Metrication And Standardization, David H. Evaul

Paper Engineering Senior Theses

The purpose of this thesis is to indicate the reactions of the paper industry and its associated industries to metrication, standardization, and their effects on the industry. In this thesis a history of the metric system is given. The metric system, as it relates to the paper industry and its associated industries, is discussed. To get direct views on how the paper manufacturers, paper merchants, and printers felt about metrication and standardization a survey was made. From this survey, the questionnaires returned indicated that the majority of the paper manufacturers, paper merchants, and printers were mildly in favor of metrication …

Transforming Ability Of Bacillus Subtilis Dna Taken Up By Barley Embryos, Christine Tolman Ence

Theses and Dissertations

Purified Bacillus subtilis DNA taken up by one-day-old barley embryos and permanently fixed within the barley cell is shown to have maintained its biological activity in B. subtilis transformation. Cesuim chloride density gradient centrifugation of DNA isolated from the roots of barley embryos after the uptake and incorporation of radioactive, bromouracil-labelled B. subtilis DNA indicates the presence of the bacterial DNA in several discreet bands of well-defined density, whose density is changed by sonication. These preliminary findings concerning the fate of bacterial DNA taken up by barley roots are discussed in terms of the recombination model of Ledoux and Huart …

Sensitivity Of Vertebrate Embryos To Heavy Metals As A Criterion Of Water Quality, Wesley J. Birge, John J. Just

KWRRI Research Reports

Embryonic and/or larval stages of the leopard frog (Rana pipiens), domestic fowl (Gallus domesticus) and the goldfish (Carassiua auratus) were treated with cadmium chloride, mercuric chloride, lead chloride, zinc chloride and sodium arsenite. The principal objectives were (1) to determine the sensitivity of vertebrate embryos to certain metals which are of consequence in water pollution, and (2) to ascertain the suitalility of vertebrate embryos as bioassay organisms for monitoring metallic pollutants within water resources. Vertebrate embryos are found to be highly sensitive to the toxic effects of all the metals studied. Concentrations of mercury as low as 10 ppb, with …

Kinesiology Of Knee Flexion Deformity Using Electromyography, Paul J. Roby

Loma Linda University Electronic Theses, Dissertations & Projects

A kinesiological electromyographic study was completed to determine the relative changes in muscle activity as a person walks and stands with different degrees of knee flexion deformity. The ultimate aim was to establish criteria for appropriate preventive and corrective measures relating to knee flexion deformity.

Six different muscles were implanted with wire electrodes. The subjects performed a series of walking and standing experiments with the knee flexed at selected angles by a locking leg brace to simulate knee flexion deformity. The electromyographic action potentials were monitored by analog tapes, oscilloscopes and closed circuit television. The analog tapes were displayed on …
