Location-Allocation Models For Establishing Facilities, David F. Gibson, John Rodenberg

Aspen Bibliography

Two models and accompanying computer programs are presented which were developed to locate facilities for the timber harvesting industry. Addressed is a case of the facility location-allocation problem. The optimum location and number of landings, facilities to which timber is transshipped, are determined so as to minimize a cost function. This function is composed of the following components: (1) cost of transporting material from its original location to a landing, (2) cost of establishing a landing (facility cost), and (3) cost of transporting material from the landings to some designated point termed the origin. Output of the computer programs is …

Water Resources Planning, Social Goals, And Indicators: Methodological Development And Empirical Test, Henry P. Caulfield

Reports

A methodology for comprehensive evaluation of water resources development and use (Techcom) has been developed and partially field tested. A model of societal goals consists of nine primary goals successively articualted into increasingly specific subgoals. Achievement of subgoals is perceived as affected by measurable social indicators whose values are perturbed by water resources actions. Linking the elements of the goals taxon by connectives result in an evaluation system. historical, political and philosophical considerations of the proposed system are discussed in Part I. Part II describes the results of the Rio Grande of New Mexico test including public perception and weighting …

An Analysis Of Water Research Programs Of The Utah Water Research Laboratory And Center For Water Resources Research, Water Resources Research Citizen Advisory Panel

Reports

Foreward: As a means of keeping water research programs at Utah State University responsive to needs in terms of both timeliness and emphasis, President Glen L. Taggart, in 1970, requested a number of Utah citizens to serve as a panel to give counsel and advice to the Utah Water Research Laboratory and Center for Water Resources Research. Membership of this 16-member panel represents a broad spectrum of water-related experience gained from a variety of professional backgrounds and organizational affiliations. The objective was to keep the panel small enough for it to be a "working" group but large enough to obtain …

Review Paper: Evaluation Of Techniques For Algae Removal From Wastewater Stabilization Ponds, E. Joe Middlebrooks, Donald B. Porcella, Robert A. Gearheart, Gary R. Marshall, James H. Reynolds, William J. Grenney

Reports

Introduction: Approximately 90 percent of the wastewater lagoons in the United States are located in small communities of 5,000 people or less. These communities, many with an average daily wastewater flow of only 175,000 - 200,000 gallons, do not have the resources to keep man at the lagoon sites throughout the day (38). A high degree of technical knowhow is usually lacking in these communities. Often only periodic inspection or maintenance is carried out by the general municipal work force. Therefore, the development of a relatively inexpensive method that does not require sophisticated and constant operation or extensive maintenance is …

Component Description Of Sediment-Water Microcosms, James Hill Iv

Reports

The development and application of complementary variables (potential and flux) for modeling environmental systems are illustrated for the hydraulic and dissolved oxygen subsystems of laboratory microcosms. These sediment-water, semi-continuous flow microcosms were used to determine nutrient interchange and mercury interactions under lighted (aerobic) and dark (anaerobic) conditions. The approach of using complementary variables to describe such systems forces a more complete conceptual understanding of the system and better attention to those parameters (many of which are unknown) requiring measurement. Complementary variables are incorporated into basic linear component equations which describe basic processes of energy transfer and transformation. The components are …

Evaluating Water Reuse Alternatives In Water Resources Planning, A. Bruce Bishop, William J. Grenney, Rengasan Narayanan, Stanley L. Klemetson

Reports

Water reuse is a recognized option for augmenting water supplies to provide for expanded water needs. A methodology is developed for examining optimal strategies for water reuse within the context of the total water resources system, including both the provision of water supplies for various uses and management of wastewaters. A model of the water resources system is formulated as a “transportation “ or “transshipment” problem in linear programming depicting the possible sources of supply, including effluent sources available for reuse, which can be used to satisfy the requirements of various water users. The optimizing objective in the model is …

Effect Of Temperature On Algal Removal By Alum Coagulation, Muhammad Anis H. Al-Layla, E. Joe Middlebrooks, Donald B. Porcella

Reports

Questions about the effect of temperature on algal cell coagulation and the relationships between algae removal and temperature, alum dosage, paddle speed, flocculation time, and settling time are answered. The investigations consisted of two series of tests: Studies on algae cultured under laboratory control, and algae in wastewater stabilization ponds. The jar-test technique was used for the coagulation of algal suspensions by alum. Coagulation of algae is caused mainly by the insoluble flocs of aluminum hydroxide. Other aluminum species also have coagulative properties but are far less effective. The destabilization of algal colloids results from enmeshment within the hydroxide precipitates, …

Nematosporaceae (Hemiascomycetidae): Taxonomy, Pathogenicity, Distribution, And Vector Relations, Lekh R. Batra

Ba

For almost a century (42, 139) certain yeast, or yeastlike parasites of fruits and seeds have been known. They occur on a wide variety of crop plants and cause such diseases as stigmatomycosis," "yeast-spot," "eye spot," and "internal rot." They seemingly represent a phylogenetic unit. They have cylindrical or pyriform asci, and the hyaline ascospores often are characteristically arranged in two fascicles lying end to end. All have acicular ascospores. (See figs. 2, a-c; 5 , c; 11, hand i; 12, A; 13, c-h; 15,j-k.) They have similar habitats, and several species may simultaneously occur in the same fruit or …

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 …

A Revision Of The Genus Iteaphila Zetterstedt Of North America (Diptera: Empididae), Douglas R. Anderson

Biology

A Complete revision of the genus Iteaphila was made. Described as new species were Iteaphila bulbosa from Alberta and British Columbia, Iteaphila longirostris from Quebec, and Iteaphila pumila from Alaska, Northwest Territories, and Yukon Terrotory. Iteaphila conjuncta was placed in synonymy with Iteaphila nitidula. This left fourteen species of the genus Iteaphila in North America. Keys to the species, descriptions, seasonal occurrences, flower records, illustrations of the male terminalia, and distribution maps were provided
