The concentrations of calcite, opal and quartz have been measured in 113 South Atlantic core tops. The remainder of the total sample has been calculated as clay. A method for the quantitative determination of opal has been developed.
Calcite is the dominant factor in South Atlantic sediments; its pattern can...
This study was designed to establish a baseline of data
regarding guidelines for curriculum development in the
preparation of health education specialists in health-care
delivery settings.
The survey method was utilized and an expert panel of
15 jurors was selected to respond to a 51 item questionnaire.
Professions represented on...
B and C horizon samples from twenty four selected profiles along
a north-south transect in the Willamette Valley were examined for
possible correlation between shrinkage properties and kind of clay
minerals present.
Observations of linear shrinkage, weight loss from a condition
of maximum plasticity, and changing character of X-ray diffraction...
The purpose of this descriptive research was twofold: 1) to
determine the expressed concerns, feelings, and needs of a selected
group of expectant fathers; and 2) to categorize those expressed
concerns, feelings, and needs into broad areas and to develop a
priority listing of those items as a basis for...
The scientific endeavors that took place at Hanford Engineer Works, beginning in World War II and continuing thereafter, are often overlooked in the literature on the Manhattan Project, the Atomic Energy Commission, and in regional histories. To historians of science, Hanford is described as an industrial facility that illustrates the...
Over the last 50 years, riparian zones in the semi-arid West have gained recognition as disproportionately important habitats for both breeding bird communities and agricultural operations. Despite growing interest in exploring avian-habitat relationships in these systems to better inform land management, few studies have attempted to describe temporal changes in...
Recent evidence suggests that population declines of some avian species may be driven primarily by reduced quantity and diversity of early-successional habitat on the breeding grounds. Increasing intensity of forest management on private lands and decreased harvest rates on federal lands has resulted in a loss of the diverse early-successional...
Driver distraction is a commonly observable phenomenon with a significant effect on the transportation network. Although the negative effects of driver distraction on safety are commonly studied, there has been little effort made to investigate the impacts of distraction on efficiency.
This study will examine driver behavior in standing queues...
