Sorption Kinetics Part I: A Laboratory Investigation Of Six Proposed Rate Laws Using Batch Reactors, David W. Hendricks, Laxman G. Kuratti

Reports

Six proposed rate equations for sorption kinetics have been investigated by laboratory batch experiments involving some 270 individual “runs” to determine sorption uptake with time for varying conditions of initial sorbate concentration, temperature, and sorbent species. The sorbate selected was rhodamine-B dye, used because it will sorb readily and is easily measured. Two sorbents, Dowex 50 resin, and Filtrasorb 200 activated carbon were used. Temperature conditions were 10, 20, 30, and 40°C, and concentrations ranged from .0008 to 400 micrograms per ml, rhodamine-B. Analysis of data was computer automated, requiring as input only test conditions, instrument readings, dilutions, and corresponding …

Social, Economic, Environmental, And Technical Factors Influencing Water Reuse, A. Bruce Bishop, Suravuth Pratishthananda, John Keith, Craig Colton, A. Berry Crawford

Reports

A growing population together with rising per capita income has resulted in increased demand for water for virtually all uses. At the same time there has been increased public concern for maintaining the quality of streams for recreation, sight-seeing, and other social uses, and to conserve environmental values. A partial answer to these conflicts in water use and management is more extensive waste water reclamation and reuse. Heretofore, water salvage and reuse has been mainly practiced in specific operational cases, such as recycling industrial process water, or on an ad hoc basis, such as a series of diversions and subsequent …

Sorption Kinetics Part Ii: Modeling Longitudinal Concentration Profiles In A Packed Bed Reactor, David W. Hendricks

Reports

A mass balance simulation model for sorption in a packed bed reactor was developed. All of the terms in the model, consisting of constants of the porous media, and functions, were evaluated by independent laboratory studies. The kinetic term was determined in Part I. Two numerical schemes (an explicit scheme and an implicit scheme respectively) with corresponding computer programs were developed and made operational. They were not tested against laboratory column results due to long times necessary on the computer and corresponding high costs. Laboratory testing consisted of measuring column profiles for six different packed columns at different flow rates …

The Effect Of The Herbicide Glyphosate On The Growth Of Selenastrum Capricornutum, Judith Susan Eisen

Undergraduate Honors Capstone Projects

The herbicide glyphosate (MON-0139), an isopropylamine salt of N- (phosphonemethyl)glycine, was tested to determine its effects on the growth of the fresh water green alga Selenastrum capricornutum. Experiments were carried out to determine algicidal, algistatic, and inhibitory concentrations of the compound.

Concentrations from 5 ppm to 1000 ppm were inhibitory to the growth of the alga, but the effects were algistatic, rather than algicidal. At concentrations from 0.1 ppm to 1.0 ppm the growth of the alga was stimulated by the presence of the herbicide, while at concentrations from 0.001 ppm to 0.05 ppm the effects of the herbicide were …

The Interaction Of Promazine With Selected Macromolecules And A Membrane Utilizing Absorption And Emission Spectroscopy, Jess D. Keeler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The association of promazine-HCl with bovine serum albumin, ammonium detergent micelles, and hemoglobin-free-rabbit-erythrocyte membranes were measured using the changes in the absorption and the emission of the interactants plus the fluorescent probe 1-anilino-8-naphthalene sulfonate. The binding of a promazine to serum protein and membrane did not alter the emission of the drug. However, the binding did produce a measurable quenching of the membrane and protein fluorescence. The quenching reaction was pH sensitive for both the protein and the membrane. Promazine binding to serum protein produced a hyperchromic change in the drugs absorption spectrum which paralleled the quenching reaction. The binding …

The Regulation Of Purine Biosynthesis In A Phosphoribosylpyrophosphate Aminotransferase-Deficient Mutant Of Salmonella Typhimurium, Wen-Cherng Tsai

Biology

The regulation of the alternate first enzyme of purine de novo synthesis (ribose-5'-phosphate aminotransferase) has been examined in pur-F 341, a purine-requiring mutant of Salmonella typhimurium deficient in the primary first enzyme (PP-ribose-P amidotransferase, EC 2.4.2.14). The ribose-5'- phosphate aminotransferase is feed-back inhibited by AMP, ADP, GDP and adenosine but not by ATP, GTP, GMP and free adenine. Pyrimidines (except CDP and UDP) and thiamine compounds show no significant inhibitory effect on ribose-5'-phosphate aminotransferase activity. The alternate enzyme seems to be also controlled at the gene-level by one or more intra-cellular purines (repression-derepression). The role of the aminotransferase in …

The Development Of Career Activities For Fourth Grade Students, Barbara P. M. Southwick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Today's youth have few real contacts with the work world and have little knowledge of what is expected from them. Many grade school youngsters are not aware of the type of work their parents are doing. Some do not even know where their parents work. It is difficult for most elementary students to see the relationship between their present school activities and their future life. And all too often, students can not express personal goals or plans.

As students become more aware of the world of work, they should be better prepared to enter it and they should also develop …
