Fault zones are potential paths for release of radioactive nuclides from radioactive-waste repositories in granitic rock. This research considers detailed maps of en echelon fault zones at two sites in southern Sweden, as a basis for analyses of how their internal geometry can influence groundwater flow and transport of radioactive...
Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental contaminants that occur in complex mixtures. These environmental mixtures can consist of both parent PAHs and their derivatives. Several parent PAHs are known or suspected mutagens and/or carcinogens, and a handful of PAH derivatives are known to be more potent mutagens and/or carcinogens...
The purpose of the study was to demonstrate the effectiveness of a safety systems approach, so designed, to reduce instructional needs by the application of research to the conceptualization and development of a computer-assisted safety management program. Procedure Two hundred accredited schools served as the respondent population for the study....
PURPOSE OF THE STUDY
This study developed a model which identified mathematical needs
in various vocational technical programs. This model provides a
method which can be used to develop an adequate mathematics curriculum
to support occupational offerings at community college/technical
institutes, and can also help high schools and the colleges/technical...
STATEMENT OF THE PROBLEM
The problem studied was whether there exist significant differences
between the perceived knowledge obtained by former secondary
cooperative work experience students as compared to the instructional
goals and objectives of these programs as identified by the Oregon
State Department of Education.
THE PROCEDURE
The problem as...
During the last 15 years, numerous geophysical surveys and geological sampling and coring expeditions have helped to characterize the tectonic setting, subsurface stratigraphy, and gas hydrate occurrence and abundance within the region of the accretionary wedge surrounding Hydrate Ridge. Because of these investigations, Hydrate Ridge has developed as an international...
PURPOSE OF THE STUDY: The study examined administrator and faculty perceptions
toward staff development needs and ascertained the
differences which exist between the reported staff development
needs of full-time community college instructors within
the state of Oregon.
OBJECTIVES OF THE STUDY:
The three objectives identified for this study were:
1....
In January-February 1971 five replicate 0.07 m² Van Veen grabs
were obtained from each of 12 stations in Arthur Harbor and nine Van
Veen grabs were obtained from two stations in nearby Bismark Strait.
The 69 grab samples yielded 78,395 individuals which were separated
into 282 taxa, including 108 species...
