Nucleophilic Substitution At Phosphorus In Six-Membered Ring Phosphate Esters, Mike Bauman
Nucleophilic Substitution At Phosphorus In Six-Membered Ring Phosphate Esters, Mike Bauman
Electronic Theses and Dissertations
From these results the following conclusions may be drawn: 1. The stereochemistry of nucleophilic substitution at phosphorus is influenced by the basicity of the leaving group with the more basic leaving group favoring retention. 2. Lithium ion diverts the reaction to retention by forming an intimate ion-pair with the nucleophile which then attacks phosphorus. This associated ion is less reactive than the unassociated nucleophile. 3. For the retention mechanism the leaving group participates in the rate determining step. 4. The mechanism for retention entails a more sterically unfavorable configuration than for inversion.

The Effect Of Potassium Permanganate On The Removal Of Iron And Manganese From Ground Water, Mohammad Reza Farvardin
The Effect Of Potassium Permanganate On The Removal Of Iron And Manganese From Ground Water, Mohammad Reza Farvardin
Electronic Theses and Dissertations
For the past three years or so, a gradual migration of iron and manganese deposits has been observed in the water mains to the west of the East Water Treatment Plant of Brookings, South Dakota. These deposits have been gradually migrating further westward from the plant (8). Routine analyses of the treated water from the East Plant indicate that the iron and manganese levels are within the USPHS recommended limits (9). Consequently, conclusive evidence that this plant is the source of the problem does not exist. However, the analyses are normally conducted on samples collected shortly before backwashing the filters. …
Specificity Of Antisera Against Hordeum Vulgare Ribonuclease And Serological Quantitation Of The Enzyme In Tissue Extracts, Steven Bryan Hawthorne
Specificity Of Antisera Against Hordeum Vulgare Ribonuclease And Serological Quantitation Of The Enzyme In Tissue Extracts, Steven Bryan Hawthorne
Electronic Theses and Dissertations
Specific rabbit antisera against purified seedling RNase I from both a hardy (Dicktoo) and less-hardy (Tennessee Winter) cultivar of winter barley was obtained using a 1 mg injection schedule. Both antisera formed a single precipitin band on double immunodiffusion and immunoelectrophoresis when reacted with the homologous crude tissue extract. RNase antigen from either cultivar was highly cross-reactive with both antisera. Passive hemagglutination inhibition was used in an attempt to distinguish purified RNase from both cultivars. A consistent difference in anti-RNase serum specificity between cultivars was shown, but the difference observed by this method was not sufficient to conclude structural differences …

Plant Availability Of Aqueous Phosphates Removed By Fly Ash, Paul D. Weeldreyer
Electronic Theses and Dissertations
Recycling non-renewable resources has become increasingly. important as man has continuously expected more and more from his environment. As stated by Spendlove (1976): "Recycling certainly is not new. It appears, in fact, to be one of the most obvious laws of nature, much like the seasons, the tides, and the life and death processes. It is not surprising, therefore, that the greatest motivating force behind present recycling efforts is the worldwide concern for the deteriorating natural environment." This ever-increasing demand for more production has created the need for more stringent pollution controls to maintain an acceptable quality of life. Pollution …
