Foreign Graduate Students’ Political Participation In Two Different Political Environments, Ragaa Ibrahim Selim

Masters Theses

Student political activism as an area of study has become less attractive to Western writers because of the sharp decline in student activism that was characteristic of the 60s. While the Western nations now discuss student activism as historical events, countries in the developing world are still engulfed with student political activism.

This research is comparative and analytic. It shows that the issue at stake in a political environment is more significant than the political environment itself; that students from the developing world are much more politically active than their counterparts in the developed world; that political participation is an …

A Study Of The Mannitol Binding Protein Active Transport System And A Catabolite Repression Resistant Mutant In Pseudomonas Aeruginosa, Joseph Arthur Wolff

Masters Theses

Cold-shock extraction procedures were used for the efficient release of mannitol binding protein. Magnesium chloride and cold-shock released 92% of the total whole cell mannitol binding protein activity without release of detectable cytoplasmic marker protein glucose-6- phosphate dehydrogenase. Arsenate inhibited mannitol uptake to the same extent as azide. The simultaneous loss and gain of mannitol binding protein activity with mannitol uptake activity in mutants and reventants respectively, was consistant with periplasmic mannitol binding protein as a required component of mannitol uptake. A catabolite repression resistant mutant for mannitol uptake was isolated and described. This mutant, designated WEP-1, escaped catabolite repression …

The Purification And Partial Characterization Of The Surface Polysaccharides From Three Fast-Growing Rhizobium Japonicum Strains, Madhav P. Yadav

Masters Theses

The fast-growing strains of R. japonicum were originally isolated from China. They are acid-producing Rhizobia and are capable of nodulating soybeans. These isolates share a common host-specificity (Peking soybean) with the slow-growing R. japonicum strains even though their biochemical properties are more closely related to other fast-growing Rhizobium species. The surface polysaccharides from three fast-growing R. japonicum strains--USDA201, USDA205, and HC205--were isolated and partially characterized. Strain HC205 is a nod⁻ mutant of USDA205 which lacks the symbiotic plasmid. These surface polysaccharides consist of extracellular, capsular and lipopolysaccharides (EPSs, CPSs and LPSs). The EPSs from all three strains are very similar …

Preference Under Concurrent Mixed Fixed-Ratio Fixed-Ratio Schedules Of Reinforcement: Control By Intracomponent Ratio Length, Earl Hall-Johnson

Masters Theses

Previous studies using concurrent variable-interval variable interval schedules have suggested that molar, not molecular variables primarily control choice responding. These studies examined pigeons performance under discrete-trial concurrent mixed fixed-ratio fixed-ratio schedules of reinforcement. When each alternative provided two reinforcements per 100 responses, pigeons preferred the alternative containing the shorter initial fixed-ratio. Subsequent studies attempted to shift preference through manipulations of ratio requirement and reinforcement duration in either alternative. Preference was shifted from the mixed fixed-ratio fixed-ratio only when the reinforcement associated with the first component was eliminated. Under all other conditions, pigeons preferred the mixed fixed-ratio fixed-ratio schedules with the …
