Development, Verification, And Use Of Methods To Model Chemical And Thermal Processes Lakes Mead And Powell, Bureau Of Reclamation

Publications (WR)

PURPOSE

The purpose of the proposed research is to quantify the effects that Lakes Mead and Powell have on the salinity in the Colorado River system, and to evaluate changes that cap be made to the operating system of the reservoirs (within legal/institutional constraints) to enhance salt precipitation and/or minimize evaporation within the reservoirs. The effect of any changes (i.e., selective withdrawal uses, pumped storage, etc.) on reservoir evaporation could also be evaluated with a goal of minimizing evaporation. This will be accomplished through the development of a mathematical model of the reservoirs as described below.

Home Range Analysis Of The Montane Vole, Don Rogers Toews

All Master's Theses

This study on Microtus montanus was divided into three major sections: 1) An examination of nests, burrows, and runways, 2) A comparison of two methods of home range analysis--live trapping and radio-isotope tracing, and 3) A comparison of the home range of Microtus montanus with other species of Microtus as published in the literature.

Preliminary Studies Of Germination Requirements Of Shadscale Atriplex Confertifolia Torr. And Ferm. Wats, Ijaz Hussain

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

Shadscale (Atriplex confertilolia (Torr. and Frem.) Wats.) is an important component of the salt-desert-shrub vegetation type in the intermountain region. This species dominates a large portion of the 41 million acres occupied by this vegetation type. Shapscale reaches greatest importance at lower elevations of Utah and Nevada, where despite the low productivity due to its harsh habitat, this vigorous shrub furnishes considerable winter grazing for sheep and cattle. Gates et al. (1966) have observed that poor drainage conditions, coupled with low precipitation, results in the concentration of salts, a chief habitat factor determining the growth and distribution of this species. …

Review Of Silvicultural Research: White Spruce And Trembling Aspen Cover Types, Mixedwood Forest Section, Boreal Forest Region, Alberta-Saskatchewan-Manitoba, J. M. Jarvis, G. A. Steneker, R. M. Waldron, J. C. Lees

Aspen Bibliography

The Department of Forestry has been carrying on silvicultural research in the white spruce (Picea glauca (Moench) Voss) and trembling aspen (Populus tremuloides Michx.) cover types in the Mixedwood Forest Section of Alberta, Saskatchewan and Manitoba for about 40 years. Because of the needs of industry most of this research has been focused on spruce, and only as small portion on aspen. Much of the research is concerned with basic problems and the findings in one area may be applied directly or with minor modification throughout the entire Mixedwood Forest Section. Only a minor part of the total …

Ecology Of Marine Invertebrate Fouling Organisms In Hampton Roads, Virginia, Dale R. Calder

Dissertations, Theses, and Masters Projects

Investigations were conducted from 15 May 1964 to 3 January 1966 to determine the incidence, distribution, and abundance of marine invertebrate fouling organisms in Hampton Roads, Virginia. Dredging carried out at seven stations revealed that benthic organisms most likely to be involved in fouling were Thuiaria argentea, Alcyonidium verrilli, Microciona prolifera, Amathia vidovici, and Aeverrillia armata. All of these species occur in the Pier 12 berthing area of the Norfolk Naval Base, with. !· argentea and~- verrilli being most abundant. Detailed studies of the organisms attaching to asbestos fiber test panels were made at Pier 12 of the Naval Base. …

Individual Sow Feeders, P Mcnamara

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

FOOD is the major cost in any pig enterprise and it is particularly easy for waste to occur in the breeding herd.

Individual feeders enable the pigman to feed each sow according to her need, and enable the sows to eat their feed slowly or quickly as they choose.
