Floating vegetation, Lemna trisulca and Cladophora sp., became abundant in both marshes during the first week of June, and formed large thick mats by the end of June 1975. Daphnia pulex was the dominant zooplankter in Bothwell Marsh and made up 33% of the zooplankton density during the 1975 season. The population was triacmic, …
Effects Of P.L. 566 Stream Channelization On Wetlands In The Prairie Pothole Region, Ronald E. Erickson
Effects Of P.L. 566 Stream Channelization On Wetlands In The Prairie Pothole Region, Ronald E. Erickson
Electronic Theses and Dissertations
The Wild Rice Creek Watershed project, in North and South Dakota was constructed under authority of the Small Watershed Protection and Flood Prevention Act (P.L. 83-566 as amended). Structural measures included 24.7 miles of channelization and four floodwater retarding dams. To measure the degree that channelization influenced drainage of prairie wetlands, drainage rates in a channelized tributary were compared to rates in an unchannelized tributary of Wild Rice Creek. Channelization had a direct impact on wetlands by channel drainage reduction of overbank flows, and by providing drainage outlets. Indirect (secondary) wetland losses are believed to have occurred outside of the …

Purine-Thiamine Anabolism During Cellular Morphogenesis In Myxococcus Xanthus, Wen-Cherng Tsai
Electronic Theses and Dissertations
Purine-thiamine anabolism during cellular morphogenesis in Myxococcus xanthus was investigated. One of the approaches was to test vegetative and myxospore (2.5 h and 8 h) extracts of M. xanthus CW-2 for their ability to synthesize the second de novo intermediate, 5'-phosphoribosylglycinamide, from beginning precursors either by way of phosphoribosyl-pyrophosphate amidotransferase (EC 2.4.2.14) or ribose-5-phosphate aminotransferase. Results indicate the presence of both the amido- and aminotransferases in both types of extracts, and both enzymes appear to be present at about the same level (per milligram of protein) in vegetative cells, myxospores (2.5 h and 8 h), and in a bacterial prototype, …

Detection Of Antibiotic Residues In Bovine Milk, Mark Edward Johnson
Electronic Theses and Dissertations
Under the Food, Drug, and Cosmetic Act antibiotics are considered as ·adulterants in milk and milk products. Cultured dairy products cannot be made with milk containing small concentrations -of antibiotics. Also, minute quantities of antibiotics cause allergic reactions in some people. Penicillin is the most common antibiotic to which people are allergic, and penicillin is also the most commonly used antibiotic in the treatment of infections in bovines. Antibiotics, whether injected intravenously or intramuscularly, or infused into the udder of the cow, can be secreted into the milk. It is for this reason that withdrawal times for milk from cows …
Free Fatty Acids Associated With Induced Rancidity In Cream And Butter, John Alan Anderson
Free Fatty Acids Associated With Induced Rancidity In Cream And Butter, John Alan Anderson
Electronic Theses and Dissertations
One of the most significant problems in the dairy industry today is the flavor defect known as rancidity. This defect has been recognized for some time, but recent trends in milk handling have increased the problem of rancidity. Recently the dairy industry on the farm has changed to the increased use of pipeline milkers and bulk handling of milk. Processing plants are becoming larger and more centralized, resulting in more movement over longer distances for the raw product. These changes result in increased foaming and agitation of the milk, contributing to the rancidity problem. The butter industry has changed. Butter …

An Evaluation Of The Fluctuations In New Car Sales For Rapid City, Denver, And The U.S. From October 1973 Through March 1975, Stephen Philip Boyer
Electronic Theses and Dissertations
During the past three years the American economy in general and the automobile industry in particular was plagued with inflation, recession, and unemployment. With sales declining during those years, profits vanished and layoffs increased within the automobile industry. One of the factors that contributed to this problem was the Arab oil Embargo of November, 1973. In the last quarter of 1973, when the automobile industry started its prolonged decline in sales, most of the Oil Producing and Export Countries (OPEC) were redirecting the world economy for their own benefit through embargoes and price fixing on their oil. Because of the …
