Zoos, aquariums and other free-choice/informal education settings offer the public opportunities to interact with live animals in exhibits through animal encounters and/or touch experiences designed to carry a conservation mission. Many of these institutions are accredited by the American Association of Zoos and Aquariums (AZA) and the World Association of...
Primary monolayer cultures of chick renal epithelial cells
grown on plastic coverslips were reversibly dissociated with the
chelating agent ethylenediaminetetraacetic acid (EDTA). The cellular
responses during dissociation and reaggregation in Hank's balanced
salt solution (BSS) were observed with phase optics and recorded
by time-lapse cinemicrography.
The epithelial cells grow as...
The Endangered Species Act of 1973 (ESA) is considered by many to be among the most powerful and most contentious environmental laws in the United States. Persistent challenges to the Act’s implementation make reaching conservation goals problematic. Most notably, the very nature of the law—providing protections for species already at...
The purposes of this investigation are twofold: (1) to identify
the functions necessary for an adequate student personnel program
in the area of the college married student and (2) to develop recommendations
based on the programs studied.
Securing and Treating of Data
The data for this study were obtained by...
There has been a rapid increase in technological advances in the biological sciences that has contributed to an increase in societal issues that require attention from both scientists and citizens. Consequently, there is a need for the development of biologically literate citizens who have the ability to use their knowledge...
This study was an experimental investigation of two methods of
teaching students the cognitive knowledge and psychomotor skills pertaining
to the automobile brake system. The methods investigated
were the experimental individualized learning system and the traditional
group-lecture and demonstration.
Experimental Design and Procedure
The experiment, conducted during the spring term...
Since the passage of the Education for All Handicapped Children Act in 1975, a number of common problems have emerged. Primarily they involve the difficulties both experienced and created by public schools attempting to fulfill the federal mandate to provide students with disabilities an appropriate public education.

The purpose of this study is to examine the relationship between land management practices of Indian communities prior to contact with Europeans and the nature or character of subsequent catastrophic forest fires in the Oregon Coast Range. The research focus is spatial and temporal patterns of Indian burning across the...
Development of a performance analysis for propeller type wind
turbines is presented. The analysis uses a strip theory approach
that includes tip-loss and blade interference. A comparison is
presented between analysis and test data. The comparison indicates
that the analysis predicts wind turbine performance to an accuracy
that is within...
