Masters Theses in the Pure and Applied Sciences

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thougtit that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.

Book Description
"Closed shedding systems have a place within North Carolina's blue crab fishery if fishers work to understand how to maintain water quality. The advantage of moving away from waterfront property without sacrificing shedding success makes this system design attractive. Key points to remember if you decide to construct a system are: [1] Design the system for the maximum number of tanks to be used. Consider not only current, but also future growth plans. Tanks can always be added, but purchasing larger pumps and/or filters later will substantially reduce profits. [2] Retain additional water in the system. More is better when it comes to water. Oversize the sump to increase overall water quality. [3] Water chemistry must be understood to operate any closed crab shedding system, however designed. Monitor dissolved oxygen, nitrite and ammonia levels more aggressively during the active season. Keep a log for water quality maintenance records to help identify problems before and after they occur. [4] Stock the system slowly. New shedding systems require a lead time of four to six weeks before adding crabs. "Shock loading" of peeler crabs almost certainly causes unnecessary crab deaths."--Summary.
