Wisconsin Versus Illinoian Age Soils: Their Effect on Agricultural Types in Ohio

Author Institution: Department of Geography, University of CalgaryA portion of the area covered by Wisconsin and Illinoian age till plain soils in Ohio was studied to determine the influence of these contrasting adjacent soil regions on farming operations and agricultural types. The study indicated that the Wisconsin age soil region is a corn-livestock agricultural region that emphasizes corn production on highly productive soils. The Illinoian age soil region, however, is a mixed farming agricultural region that emphasizes soybean production to help overcome the limitations of the much less productive soils. The difference in the soils does affect differences in the agricultural types imposed on them

Attitudes toward planned work experience for foreign students

The purpose of this study was to examine the attitudes of selected foreign students at Iowa State University, their faculty advisors and selected Iowa manufactureres toward involvement in a planned work experience for foreign students. Items on the questionnaire mailed to those surveyed included key situational and personal variables, statements regarding attitudes toward involvement in a planned work experience, and terms and conditions providing logistical and administrative limits to the proposed model. Respondents were asked to indicate those terms and conditions which present the most concern relative to the success of a planned work experience;Findings determined that students\u27 attitudes toward involvement in a planned work experience differed significantly from those of faculty advisors and Iowa employers on over half the thirty items. These differences, however, were generally in terms of the degree of common agreement or rejection of the items. Items of broad agreement include statements suggesting that involvement would give the student participant useful management experience, advantages in professional advancement upon return home, and would not unnecessarily delay return home. Strengthened ties between academic departments and the business/professional community were expected to result from such involvement, and valuable cultural information transfers to the employer were expected to occur as well. Pay levels somewhat below regular salaries for comparable new American trainees were agreed to by a majority of respondents, but the desired minimum length of a planned work experience varied from approximately one year among students to an average of sixteen weeks, according to Iowa employers. The nature of the trainee assignment--rotation among divisions, special assignments, etc.--was agreed to be the term or condition of most concern to all parties in terms of success of a planned work experience. While the English language abilities of trainees were of concern to both employers and faculty advisors, they were not among the three most critical terms or conditions influencing success of a model program. Conclusions indicate that all groups broadly agree to the importance of a planned work experience and that Iowa export manufacturers were receptive to participation in such a model program

The Effect of Urban Development on Peak Water Flow, Bowling Green, Ohio: 1950-1969

Author Institution: Department of Geography, University of Calgary, Allen County Planning CommissionAn attempt is made to analyze land use changes and resultant increases in peak water flow in an urbanizing area. The study compares land use, infiltration, and peak water flow for a 16 mile2 area centered on Bowling Green, Ohio, for 1950, before accelerated urban development, with the same area for 1969, after development. Peak water flow increases attributed to urban development on former agricultural land, and the resultant problems of drainage and excess water, are of specific concern. In the study area, a combination of near-level topography, clay-rich soils, and paved commercial areas produce a peak water flow greater than the capacity of storm drainage ditches. Storm drainage facilities are not adequate to handle the increased peak water flow caused by urban development demonstrating the need for proper land use planning prior to urban development

Analyzing Binding Data

Measuring the rate and extent of radioligand binding provides information on the number of binding sites, and their affinity and accessibility of these binding sites for various drugs. This unit explains how to design and analyze such experiments. Curr. Protoc.

Solubilization and chromatographic separation of gonadotrop in receptor from adenylate cyclase in ovarian preparations

The distribution of gonadotropin receptor and adenylate cyclase activities has been monitored in Sepharose 6B chromatographic eluates of a Lubrol solubilized fraction of 25 day old rat ovarian tissue. The receptor was resolved from the adenylate cyclase activity. Chromatography of a gonadotropin desensitized rat ovarian preparation showed that the desensitized preparation contained normal amounts of the adenylate cyclase activity when compared with the control ovarian preparation, but there was a marked reduction in the receptor activity in the desensitized ovaries. This study demonstrates that in ovarian tissue adenylate cyclase is a separate entity distinct from the receptor molecule and that the desensitization causes a reduction in the receptor activity with no detectable change in the catalytic and chromatographic properties of the adenylate cyclase.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/23312/1/0000251.pd
