Selecting Non-Point Source Pollution Treatment Practices Using Linear Optimization, John Gardy Garland Iii

Civil & Environmental Engineering Theses & Dissertations

This paper provides a case study application of a linear optimization program as a water quality management tool. The optimization program seeks to minimize the cost of nonpoint source pollution control by selecting the best combination of pollution control management practices for Hampton, Virginia. The management practice options are grass swale roadways, porous pavers, ponds, detention basins and fertilizer management education. Management practice selection is limited by constraints on land-use and water quality. Pollutants evaluated are total nitrogen, total phosphorus, suspended solids, fecal coliforms and biochemical oxygen demand (five-day). The value in the water quality constraints for pollution loading on …

Lung Cancer Incidence In A Chinese High Background Area — Epidemiological Results And Theoretical Interpretation, Werner Hofmann, Robert Katz, Chunxiang Zhang

Robert Katz Publications

A survey of inhabitant exposures arising from the inhalation of radon and thoron daughters, and lung cancer mortality has been carried out in two adjacent areas in Guangdong province, China, designated as the "high background" and the "control" area. Annual exposure rates are 0.38 WLM/yr in the high background, and 0.16 WLM/yr in the control area, while age-adjusted mortality rates are 2.7 per 105 living people of all ages in the high background, and 2.9 per 105 in the control area. From this data we conclude that we are unable to determine the excess lung cancer rate over normal fluctuations …

Classification, Paleoecology, And Biostratigraphy Of Crinoids From The Stull Shale (Late Pennsylvanian) Of Nebraska, Kansas, And Iowa, Roger K. Pabian, Harrell L. Strimple

Bulletin of the University of Nebraska State Museum (1924–2023)

Thirteen species of crinoids representing the families Diphuicrinidae, catacrinidae, Pirasocrinidae, Erisocrinidae, Cromyocrinidae, Cymbiocrinidae, Scytalocrinidae, and Ampelocrinidae have been collected from the Stull Shale Member of the Kanwaka Formation in the Shawnee Group of the Virgil Series (Upper Pennsylvanian) from near Weeping Water and Plattsmouth, Nebraska, and near Pacific Junction, Iowa. Exposures of the Stull Shale near Melvern, Kansas, have yielded 14 species of crinoids representing the families Diphuicrinidae, Catacrinidae, Pirasocrinidae, Lophocrinidae Allagecrinidae, Cymbiocrinidae, Erisocrinidae, Apographiocrinidae, and Stellarocrinidae. All but two of the species present in the Stull Shale have been previously reported from other stratigraphic horizons, including the Vinland Shale …

Documentation Of Whole-Farm Model For The Eastern Wheatbelt Of Western Australia, Ross S. Kingwell, David J. Pannell, David. A. Morrison

Grain and other field crops published reports

The Eastern Wheatbelt Model (EwM) is a hypothetical farm model, intended to be representative of farms in the eastern wheatbelt region. It is a model of an 'average' farm in an 'average' season. Nevertheless it is possible to substitute the resource mix of a 'real' farm for the •average' and to substitute various types of season for the 'average'.

Assumptions of 'average' farm resources and •average' season are based on opinions by WADA researchers and advisers. For the EWM, researchers and advisers at Merredin prescribed average resources for an eastern wheatbelt farm receiving a 300 mm average rainfall including 210 …

Alfalfa In Livestock Feeding Programs, Gary T. Lane

Kentucky Alfalfa and Stored Forage Conference

A magazine article entitled "Bidders Paid More For Quality at Wisconsin Hay Auction" caught my attention. Did they really pay more money for higher quality. I could not help but think of some hay sales which I have witnessed. One dollar per bale, large bales, small round bales, sixty dollars per ton, and $275 per ton are all some quotes I have heard recently in connection with hay purchases. Not much is said about quality. We may hear relative terms such as good, not much grass, cut early, not rained on or others but not much about nutrient content or …

Grazing Alfalfa, Charles T. Dougherty

Kentucky Alfalfa and Stored Forage Conference

Alfalfa (Medicaao sativa) is a native of an area south of the Black and Caspian seas and it still grows wild in Iran and eastern Anatolia. Alfalfa was the chosen forage for the fighting horses of ancient armies as long ago as 1800 B.C. when the Kassites conquered Babylon. The spread of alfalfa followed the pathway of armies through the Mediterranean, Europe, and the New World. For ages before man used alfalfa to fuel his fighting animals natural selection processes worked on the evolution of alfalfa and its predecessors. A scenario which would account for the morphology and …

Chemical Preservation Of Alfalfa Hay, Dan O. Riddell

Kentucky Alfalfa and Stored Forage Conference

Kentucky farmers harvest about 3 million tons of hay annually. In order to minimize dry matter losses and quality deterioration, hay should be baled with about 20% moisture. Unfortunately, adequate time required to field-dry hay to 20% moisture is often not available due to weather conditions. This is especially true for the first cutting of alfalfa in the spring. Many farmers are forced to choose between letting cut hay get rained on or baling hay wetter than is recommended. Hay baled with more than 20-25% moisture generally becomes moldy and undergoes a heating process which makes part of the protein …

Biological Control Of Alfalfa Insect Pests, Chris M. Christensen

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is a succulent plant that obviously is good feed for large herbivores such as cattle and horses. Therefore, it should not be surprising that a large number of small herbivores such as insects also find this plant delicious. Fortunately, most of these insects are not major pests. However, we do have a couple pest insects that annually attack this valuable crop and often cause economic damage.

Controlling insect pests is expensive and time consuming. However, not controlling them can be disastrous to the profit margin of the alfalfa producer. Entomologists who work on the insect pests of alfalfa have …

An Application Of Discrete Optimization For Developing Economically Efficient Multiple-Use Projects, United States Department Of Agriculture, Forest Service

Forestry

A discrete version of the continuous joint production model in economic theory is presented for use in designing multiple-use projects and identifying efficient management prescriptions for forest planning. Data requirements are less demanding than the continuous theoretical model, yet some of the more important features are maintained. Models can be formulated graphically or as mixed-integer programming problems that are easily solved via computerized routines.

Response Of Grass Species To Tree Harvesting In Singleleaf Pinyon-Utah Juniper Stands, United States Department Of Agriculture, Forest Service

Forestry

Cover, yield, and nutrient concentrations of grasses were sampled on tree-harvested and nonharvested plots on north, west, and south aspects of a singleleaf pinyon (Pinus monophylla)-Utah juniper (Juniperus osteosperma) stand. Grass cover increased rapidly the first 2 years following tree harvest, but the rate of increase declined over the next 2 years. Grass yield varied among aspects and soil microsites on tree-harvested plots but not on the nonharvested plots where tree competition masked aspect and microsite effects. All grass species had greater yield and greater percentage nitrogen and phosphorus on harvested than on nonharvested plots. Low digestibility of some species …

The Trinidad And Tobago/Venezuela Fishing Agreement, Zaleena K. Chin-Yuen-Kee

Marine Affairs Theses and Major Papers

The twin-island Republic of Trinidad and Tobago is situated adjacent to the Republic Of Venezuela such that at one point Trinidad is merely seven miles off the northeast coast of Venezuela. Fishing activities of nationals of each country in the waters of the other are therefore common and often lead to conflict. In an attempt to solve the fishing problem a fishing agreement was negotiated. It came into force in 1978 and expired in 1984 whereupon negotiations commenced once more in an attempt to achieve new accord. The fishing industries of both countries and the conflicts which led to the …

U.S./Japanese Fishery Relations: Reflections On The Past And The Unsettled Future, Matthew Axel

Marine Affairs Theses and Major Papers

U.S.-Japan fisheries history spans over a half-century of controversy. A variety of developments have taken place over this period from past to present illustrating this point. This paper will present this subject in three parts, corresponding to the historical developments that have taken place. The saga begins with U.S. post-World War II aid in rebuilding the Japanese tuna, whaling and salmon fleets. Round two examines the rapid expansion of the Japanese utilization of Alaska pollock and the development of the surimi trawlers in the early 1960s. Finally, round three, which will encompass the majority of the subject matter discussed, begins …

Cooperatives: Their Effectiveness And Limitations For Small-Scale Fisheries Development, Hiroaki Yonesaka

Marine Affairs Theses and Major Papers

Increased experience in fisheries cooperatives of developing countries has called into question a long-held presumption about their desirability and feasibility. In this context, this study attempts to reformulate the cooperative approach for small-scale fisheries in a realistic policy framework. First, past failures of fisheries cooperatives are analyzed from three different angles: the uniqueness of the fishing industry, systems intrinsic to the cooperative, and development policy. Second, various possibilities of building viable cooperatives are explored by introducing two key concnpets: the strategic option and the operational option. On the one hand, the strategic option implies that it is imperative to integrate …

Premium Prices For Quality Fish: A Case Study Of The F/V Odin, John Sackton

Marine Affairs Theses and Major Papers

During 1982, the F/V ODIN, a fishing vessel from the Port of New Bedford, participated in a program to improve fish quality on board through use of innovative fish handling techniques. The captain and crew hoped to sell higher quality fish at a premium price. This thesis examines the prices the F/V ODIN received prior to participating in this experiment, the price differentials the vessel actually received for landing higher quality fish, and the impact of the program on the prices received by the ODIN following the project. Overall, the ODIN received a price premium equal to 7.2% of the …

The New England Fishing Industry: A Case For Altering Conditions Of Competition In Both The Fishery And In The Market, William Joseph Brennan

Marine Affairs Theses and Major Papers

The New England fishing industry is presented in detail including an historical review, a discussion of current difficulties, and an examination of the public policy dilemma between resource conservation and industry promotion. Continuing efforts to revitalize the United States fishing industry are discussed and underlying problems that have had a negative impact upon the New England industry are outlined. Finally, an alternative public policy approach is developed which addresses fundamental difficulties in the new England region. This approach calls for an elimination of federal financial assistance to the fishing industry and a reduction in the amount of fishery imports reaching …

Biology Of The Antarctic Krill (Euphausia Superba) And Fisheries Management Under The Convention On The Conservation Of Antarctic Marine Living Resources, Randa Ali Mansour

Marine Affairs Theses and Major Papers

Interest in the development of a commercial fishery for Antarctic krill, the lack of a legal regime to govern and promote rational exploitation of Antarctic living resources, and a desire to avoid future conflicts between claimants and non-claimants regarding the control of an Antarctic marine fishery, as well as the desire to set a precedent for management and exploitation of non-living resources were incentives for the negotiation of the Convention on the Conservation of Antarctic marine Living Resources (CCAMLR). Furthermore, the Antarctic Treaty Consultative parties wished to maintain and solidify their control and enhance their collective legitimacy in the Antarctic …

Interstate Fisheries Management Problems: The Case Of Striped Bass, Richard Randall Schneider

Marine Affairs Theses and Major Papers

The striped bass (Morone saxatilis), or rockfish, fishery has been important both commercially and recreationally for decades along the Atlantic seaboard. In recent years, though, the fishery has undergone a serious decline and, as a result, has elicited considerable public concern. Although specific reasons for the decline have not been pinpointed, it is clear that inconsistent management practices within the range of striped bass have done little to help the fishery's condition. An anadromous species, striped bass spawn in the fresh water reaches of estuaries, after which many of the individuals return to the coastal ocean. In the Atlantic, the …

The Green Movement: Implications For Animals, Ronnie Z. Hawkins

Environment Collection

The Green movement, a newly emerging political movement that is both global in scope and firmly anchored to each local region at the grassroots level, is destined to be of great import to those concerned with the status of nonhuman animals in our society. Closely allied with deep ecology and bioregionalism, Green thinking embodies an alteration in our perception of the human organism: no longer seen as separate from and superior to all the other components of the ecosystem, our species is placed in context as one among many interdependent forms of life, with the attainment of a sustainable balance …

Predicting Duff And Woody Fuel Consumed By Prescribed Fire In The Northern Rocky Mountains, United States Department Of Agriculture, Forest Service

Forestry

This paper presents numerical relationships of known precision for predicting duff consumption. They were established by assembling and analyzing data from three previous prescribed fire investigations and then testing them against other published data. Fuel loadings by diameter classes that differed among the studies were converted to a common set of diameter classes. The purpose of assimilating data from several studies was to develop predictive models that could be easily used by practitioners and that would apply over a wide range of conditions.

Applying Height Growth And Site Index Curves For Inland Douglas-Fir, United States Department Of Agriculture, Forest Service

Forestry

Methods for estimating both site index and dominant height growth for inland Douglas-fir in the Northern Rocky Mountains are presented and discussed. The methods should be applicable over a wide range of stand conditions because no restrictions were placed on species composition, stand density, spacing, or age structure in the original stem analysis sample. Increased accuracy can be obtained if habitat type is considered, because the shape of the site index curves varied with respect to three major habitat series groupings. Results are summarized in the form of equations, tables, and graphs. Precision curves are used to illustrate the relationship …

Effects Of Bifenox, Dcpa, And Napropamide On Ectomycorrhizal Development Of Conifer Seedlings In Central And Northern Rocky Mountain Nurseries, United States Department Of Agriculture, Forest Service

Forestry

Postseeding and postgermination treatments with three weed control herbicides (Bifenox, DCPA, Napropamide) at two rates of application caused little reduction of ectomycorrhizal development on 1- and 2-year-old conifer seedlings in Central or Northern Rocky Mountain nurseries. In many cases, herbicide treatment increased ectomycorrhizal development, particularly with DCPA. In general, herbicide treatment effects on ectomycorrhizal development were species and nursery specific.
