Hybrids between wheat and jointed goatgrass have long been presumed to be sterile; however, seed were found on hybrid plants in 1990. Field studies were conducted in 1995 and repeated in 1996. One to ten hybrid plants were planted in variable populations of wheat and jointed goatgrass to determine the...
Analysis of profiles measured over irrigated cotton in the Sudan Gezira showed that the crop boundary
layer remained stable throughout most of the day. The shape of wind profiles measured within the canopy
suggested that momentum was absorbed mostly in the upper layers of the canopy, with the lower regions...
Gastric retention time of single unit dosage forms in swine was found
to be much longer than in humans. It was concluded that swine are not a
good animal model to study GI transit time of nonerodable or slowly eroded
dosage forms. Noneradable and slowly eroded dosage forms used to...
A 140 bed community hospital was the setting where the development
and evaluation of a computer aided patient profile review system took
place. This clinically oriented system involved the review of patient's
drug regimen, diet, allergies, and laboratory tests for well documented
contraindications or interactions. The pharmacist was involved in...
