Tracheal mite parasitism of honey bees

Creator:: Royce, Lynn A.
Abstract:: The tracheal mite, Acarapis woodi (Rennie), parasitizes the honey bee, Apis mellifera L., an insect used extensively by humans for pollination of domestic crops and for bee products, primarily honey. This parasite was first discovered in 1921 on the Isle of Wight, a small island situated in the English Channel...

Consequences of coumaphos and Varroa destructor on drone honey bee sperm quantity

Creator:: Delaney, Deborah Anne
Abstract:: The number of drones and genetic diversity among drones are essential components to a well mated queen. Varroa destructor preferentially parasitizes drone brood, and is thought to be responsible for the loss of feral populations that once provided additional drones for honey bee mating areas. It is necessary to use...

Water quality impacts of free ranging cattle in semi-arid environments

Creator:: Larsen, Royce E.
Abstract:: The purpose of this study was to evaluate the effects that free ranging cattle have on water quality in semi-arid environments. There were three specific objectives: 1) To determine the concentration and distribution of cattle feces in meadows, riparian zones, and the associated uplands. 2) To determine the fecal deposition...

Area efficient D/A converters for accurate DC operation

Creator:: Greenley, Brandon Royce
Abstract:: The design of mixed-signal integrated circuits has evolved from simple analog and digital circuits operating on the same silicon substrate to the point that now we have complete system on a chip solutions for communication systems. The levels of integration needed to remain cost effective in today's integrated circuit (IC)...

Carbohydrate metabolism in lactic streptococci with special reference to galactose

Creator:: Lee, Donald Royce
Abstract:: Phosphorylation of free galactose by lactic streptococci was mediated by an adenosine triphosphate (ATP) dependent kinase which was repressed by glucose. The phosphoenolypyruvate (PEP) phosphotransferase system (PTS) was not involved in transport of galactose, The conversion of free galactose to glucose was also demonstrated. A key Leloir pathway enzyme, uridine...

An investigation of bivariate approximations

Creator:: Bills, Gary Royce
Abstract:: The three important methods of approximation; interpolation, least- squares, and Chebyshev, are extended into bivariate approximations. A method of obtaining polynomial approximations for very general classes of bivariate samples is developed. Bivariate least - square approximations are reviewed and a method of developing bibariate orthogonal sequence is derived. A method...

The distribution of leakage radiation from an unshielded diagnostic-type x-ray tube housing

Creator:: Gragg, Royce Lynn
Abstract:: The objective of this study was to determine the distribution of leakage radiation from two unshielded diagnostic-type X-ray tube housings. This information was used to determine the shielding required in the housings to bring them into compliance with the definition of a diagnostic-type protective tube housing, as set forth by...
