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...
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...
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...
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)...
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...
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 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...
