Suitability Of Water From A Gravel Pit Pond In East Brookings As A Public Water Supply, Timothy Dean Stefanich
Suitability Of Water From A Gravel Pit Pond In East Brookings As A Public Water Supply, Timothy Dean Stefanich
Electronic Theses and Dissertations
The national concern for the safety of America’s drinking water supply was renewed in 1974 by the passage of the Safe Drinking Water Act. The concern for water supply source protection had also begun especially in rapidly developing areas. Because of these limitations, source protection is regarded as a major step in protecting a present or future water supply from contamination. Thus, the knowledge of both ground and surface water movement near a present or future source of water and the potential of its contamination is very important. A large groundwater source, known as the Big Sioux Aquifer, exists in …

A Comparative Study Of Traditional Nursing Schedules Vs. Extended Nursing Schedules On Patient Satisfaction, Cheryl J. Erler
A Comparative Study Of Traditional Nursing Schedules Vs. Extended Nursing Schedules On Patient Satisfaction, Cheryl J. Erler
Electronic Theses and Dissertations
This study compared patient satisfaction with nursing care given by nurses working traditional eight-hour shifts versus the satisfaction of patients being cared for by nurses working twelve-hour shifts.
The conceptual framework was derived from Systems Theory incorporating the interrelated subsystems within the organization that contribute to patient satisfaction as identified by Johnson, Kast, and Rosenzweig (1973).
The Patient Satisfaction Instrument designed by Risser(1975) and adapted by Hinshaw and Atwood (1979) for in-patient use was utilized for data collection. One medical-surgical unit in a Veterans Administration Hospital constituted the experimental group where patients were surveyed before and after the staffing change. …

A Contrastive Study Of The Phonological System Of English And Korean, Yeon-Ki Chae
Electronic Theses and Dissertations
This study is intended as a contrastive analysis of selected aspects of the phonological systems of English and Korean. Contrastive analysis is basically the manner in which most foreign language courses are taught. The field of contrastive linguistics has recently split into three areas: traditional contrastive analysis, error analysis, and interlanguage. Contrastive analysis is concerned with the comparison of two languages in order to determine both the similarities and differences between them. This study is based phonology which compares on the theory phonological of contrastive languages in order to determine areas properties of two in the phonological system of one …

Custer State Park's multiple-use management plan stresses compromise among resource users. The objective of integration of forest, wildlife and recreational resource management is to provide maximum benefits to all sectors of the management plan. Forest management techniques have a marked influence on the unique wildlife populations of Custer State Park. To provide input for individuals making integrated management decisions, an approach was taken to combine forest stand and soil survey information, to assess understory herbage production for deer and elk grazing. Thinning pine stands will increase forage and browse production. Slash left from thinning and timber harvesting operations is suspected …
Studies On The Sterile-Insect Technique As A Means Of Controlling The Stable Fly, Stomoxys Calcitrans (L.), In A Beef Cattle Feedlot In Brookings, South Dakota, Michael Aguilar Catangui
Studies On The Sterile-Insect Technique As A Means Of Controlling The Stable Fly, Stomoxys Calcitrans (L.), In A Beef Cattle Feedlot In Brookings, South Dakota, Michael Aguilar Catangui
Electronic Theses and Dissertations
The stable fly is usually the only biting, blood-sucking fly breeding in appreciable numbers in and around confined animal facilities. An average number of 50 flies per animal can reduce the weight gains of calves on a growing ration by 0.9 kilogram per day. At present, the level of 5 stable flies per front leg of confined beef cattle is used as an indicator of the economic threshold when control measures must be instituted. Since the immature stages of the stable fly develop in decaying organic matter, the most practical control measure has been sanitation or the proper storage and …
Anaerobic Codigestion Of Whey In Municipal Sludge Digesters, Allan Dean Erickson
Anaerobic Codigestion Of Whey In Municipal Sludge Digesters, Allan Dean Erickson
Electronic Theses and Dissertations
Anaerobic digestion is a method of sludge stabilization commonly used by municipalities on wastewater sludges. The process takes place in a-sealed vessel in the absence of free molecular oxygen and biologically converts a portion of the organic material to primarily methane and carbon dioxide gas. The methane, which is the major component of natural gas, may be used as a source of energy for the treatment plant. The wastewater treatment facility utilized in this study was located in Sioux Falls, South Dakota. This facility uses the methane produced in the anaerobic sludge digestion process to heat the digesters as well …

Surface runoff, soil water storage and evapotranspiration values were 8, -8 and 100% of total water input values during a study period from late June to mid-August. Evapotranspiration values averaged 7.1 mm/day for the study period. Deep percolation loss was calculated to be zero. The Inter-Row Tillage treatment produced less surface …
An Economic Analysis Of Alternative Farming Systems In Northeastern South Dakota, Mark Gene Leddy
An Economic Analysis Of Alternative Farming Systems In Northeastern South Dakota, Mark Gene Leddy
Electronic Theses and Dissertations
This thesis research focused on the economic viability of alternative farming systems which forego chemical inputs and emphasize crop rotations and legumes. The alternative farming systems were found to have distinctly lower direct cash costs of production. However, in one set of comparisons, these lower direct cash costs were not enough to offset the lower gross income received with the alternative system; thus, this system exhibited the lowest net return over costs. In the other set of comparisons, the lower direct costs were of sufficient magnitude for the alternative system to exhibit the highest net return over costs. Sensitivity analyses …

Habitat Selection And Sexual Suggestion Of Rocky Mountain Bighorn Sheep In Custer State Park, South Dakota, Larry J. Layne
Habitat Selection And Sexual Suggestion Of Rocky Mountain Bighorn Sheep In Custer State Park, South Dakota, Larry J. Layne
Electronic Theses and Dissertations
Spatial segregation between Rocky Mountain bighorn sheep (Ovis canadensis canadensis) ram and ewe herds has been documented by Geist (1971), Geist and Petocz (1977), Shank (1979), Morgantini and Hudson (1981), and Hogg (1983), where ram herds consist of mature males approximately 4 years old and older and ewe herds are comprised of all other individuals. Geist (1971), Shank (1979), and Hogg (1983) have shown that segregation occurs year-round except during the breeding season (November and December) when the sexes congregate on a traditional breeding range (cf. Geist 1971, p 209). These studies also have shown that the sexes remain separated …

Growth And Proteolytic Activity Of Selected Psychrotrophic Bacteria In Whole Milk And Whole Milk Retentate, Ravinder Reddy
Electronic Theses and Dissertations
In the last twenty years a number of membrane separation processes have evolved from laboratory scale, through pilot plant investigation, to full scale production units. One such process, ultrafiltration, has been found particularly useful in the dairy industry. Ultrafiltration uses porous polymeric membranes to separate molecules, principally on the basis of their molecular weight. In milk, fat, protein and associated substances are retained on the membrane. Permeate, which passes through the membrane contains mainly water, lactose and other low molecular weight substances. There is interest in ultrafiltration of milk because of it is potential importance in saving costs to both …
