Effects of experience on microcomputer use in primary schools : results of a second survey
(1988)
Following an initial survey of microcomputer use in Hertfordshire primary schools, a second, follow-up survey was conducted two years later to examine how experience had changed attitudes and use. This second survey provided ...
Approximate expressions of maximum value of stress intensity factor of nozzle corner cracks
(1988-01-01)
Based on the flat plate-nozzle model loaded by uniform uniaxial tension, through some suitable reduction and approximation, the maximum value of stress intensity factor (K) along a crack front can be expressed by the weight ...
In vitro transcription in plant nuclei
(1988)
Isolated plant nuclei can be used for fundamental studies on the transcription apparatus. Total RNA polymerase activity can be measured using plant nuclei, and by using different α-amanitin concentrations in the enzyme ...
Comparison of ivermectin, oxfendazole and levamisole for use as anthelmintics during the periparturient period in sheep
(1988)
Ewes synchronised with progestin impregnated sponges to reduce the spread of lambing were treated during the periparturient period with anthelmintic. The suppression of nematode egg output in faeces was measured in ewes ...
Random walk models of binary choice : the effect of deadlines in the presence of assymetric payoffs
(1988)
Random walk models of binary choice were evaluated using line length discrimination tasks of varying difficulty. Subjects' gained monetary payoffs when their responses were correct and lost when their responses were ...
Palmitoyl carnitine : an endogenous promoter of calcium efflux from rat heart mitochondria
(1988)
The effects of the fatty acid ester palmitoyl carnitine (PC) on mitochondrial Ca2+ handling and ATP synthesis are described. At low concentrations (5–40 μM) PC was found to produce changes in mitochondrial Ca2+ handling, ...
