This report describes the Graphical Editor part of DataLab, a visual programming tool for the specification and synthesis of abstract data types (ADTs). DataLab consists of two major components: graphical editor and source code generator. The graphical editor is used to design an abstract data structure and its operations by...
The shallow, poorly-confined, sand and gravel aquifer underlying the lower
Malheur River basin is contaminated by nitrate and metabolites of the herbicide
dimethyl tetrachloroterephthalate (DCPA), first detected in 1983 and 1985,
respectively. The aquifer supplies water for the Ontario municipal water system,
domestic and industrial uses, and irrigation. In response...
The fecal flora of healthy bottle or breast-fed infants was
examined for the presence of Bifidobacterium. Identification was
based on the presence of fructose-6-phosphate phosphoketolase,
which is found only in these bacteria. No bifidobacteria were
recovered from bottle-fed infants. However, bifidobacteria were
readily isolated from 15 day to 3 month...
Potential sources of inoculum of Phialophora malorum
were investigated. P. malorum was found to be a soil-borne
fungus whose role as a postharvest pathogen of pear is
dependent upon passive dispersal with infested soil. P.
malorum survived in soil under a wide range of conditions,
with greatest survival in cool,...
Recent advances in courtship theory emphasize day-today
interaction and the environment in which interaction
takes place as critically important in the understanding of
relationship development. The purpose of this study was to
determine the influence of college course assignments on
time spent in relationship activities and, similarly, the
influence of...
