Microbial Degradation Of Oxalate In The Gastrointestinal Tracts Of Rats, Steven L. Daniel

Steven L. Daniel

Rates of oxalate degradation by mixed bacterial populations in cecal contents from wlld rats ranged from 2.5 to 20.6 µmol/g (dry weight) per h. The oxalate-degrading activity in cecal contents from three strains of laboratory rats (Long-Evans, Wistar, and Sprague-Dawley) from four commercial breeders was generally lower, ranging from 1.8 to 3.5 µmollg (dry weight) of cecal contents per h. This activity did not increase when diets were supplemented with oxalate. Wben Sprague-Pawley rats from a fifth commercial breeder were fed an oxalate diet, rates of oxalate degradation in cecal contents increased from 2.0 to 23.1 µmollg (dry weight) per …

Carbon Monoxide-Dependent Chemolithotrophic Growth Of Clostridium Thermoautotrophicum, M. Dean Savage, Zhongren Wu, Steven L. Daniel, Leon L. Lundie Jr, Harold L. Drake

Steven L. Daniel

The acetogen Clostridium thermoautotrophicum was cultivated under CO-dependent chemolithotrophic conditions. CO-dependent growth profiles and energetics indicated that supplemental CO2 was fundamental to efficient growth at the expense of CO. Overall product stoichiometry approximated 6.5CO --> CH3CO2H + 3.5CO2 + 0.6 cell C + 0.5 unrecovered C. Initial CO/CO2 ratios of 2 to 4 yielded optimal doubling times and cell yields. Maximal YCO values approximated 2.5 g of cell dry weight per mol of CO consumed; Y H2 , was considerably lower than Y CO Cross-transfer growth experiments and protein profiles indicated differential expression of genes between CO and methanol cultures.

Information Sources Used By High School Seniors, Charles G. Eberly

Charles G. Eberly

College choice is a critical decision facing many high school students. Although some research has examined where students go for help in making college choices, few studies have examined how race or gender differences of the students or differences in their standardized test scores affect their information sources. Entering college freshmen (N=3,708) indicated which ~f nine information sources (college students, friends, high school counselor, college publication, family, alumni, high school teacher, newspaper, tel~vision) they used in selecting a college.

Responses were analyzed separately for females and males, blacks and whites, in each of four American College Testing (ACT) score categories. …

New Mesoamerican Species Of Cyperus (Cyperaceae), Gordon C. Tucker

Gordon C. Tucker

Four species of the genus Cyperus are described, illustrated, and compared to their nearest relatives. These are: C. matudae and C. breedlovei (Subgenus Protocyperus) from the Pacific slope of Chiapas, Mexico; and C. wilburii and C. svensonii (Subgenus Cyperus) from the lowlands of the Isthmus of Tehuantepec, and from the uplands of Chiapas, Guatemala, Honduras, and Nicaragua, respectively.

Multiple Paternity In A Territorial Passerine: The Bobolink, Thomas A. Gavin, Eric K. Bollinger

Eric K. Bollinger

Electrophoretic and behavioral evidence corroborate the conclusion that Bobolink (Dolichonyx oryzivorus) females occasionally copulate with more than one male, which results in the insemination of a single clutch of eggs by those males. In 2 of 12 families from which blood samples were obtained from the mother, the putative father, and the nestlings, at least 2 males were responsible for fertilization of the clutch. We believe this is only the second bird species in which multiple paternity has been documented conclusively in the wild. Our speculation that it may not be uncommon leads to a caution for evolutionary biologists who …

An Alternative Analysis For The Situational Attitudes Scale, Charles G. Eberly

Charles G. Eberly

A re-analysis of the Situational Attitudes Scale (SAS) was conducted to investigate lts generality, validity and reliability and to suggest a more conservative method of analyzing the data. Three forms of the SAS were developed under the name Situational Attitude Inventory. Forms A and B corresponded to the originals; they tested attitudes toward whites and blacks, respectively, in varying social situations. Form c was developed to test the validity of the social situations for differentiation among alternative referents, which included welfare, age, ethnicity, and physical characteristics. The SAS was administered to a random sample of new freshman and transfer students …

Residence Hall Program And Perception Of University Environment, Charles G. Eberly, Eugene J. Cech

Charles G. Eberly

I have always maintained that at-risk students were often blamed for their lack of success, rather than supported to overcome their prior educational challenges. As a second year residence hall director I had the privilege of working in a building with two distant wings. With the support of my mentor, Dr. Eugene J. Cech, Director of Testing, we developed a residence life program designed to assist summer lower-quarter high school graduates to be successful in college. The quality of residence life does make a difference. The journal, College Student Survey, no longer appears to be published.

The Influence Of The Fraternity Ritual, Charles G. Eberly

Charles G. Eberly

The article was based on a section of my 1966 master's thesis from Syracuse University, in which I surveyed the Grand Chapter officers and undergraduates from two chapters of a national fraternity on several topics that I thought were important to fraternity life at that time. Interestingly, the article remains one of relatively few focues on the fraternity ritual and its application to daily life even after 45 years' time. The journal, College Student Survey, no longer appears to be published.
