Hydrogen abstraction from 1-substituted adamantanes

Creator:: Owens, Peter Halliday
Abstract:: The relative rates of bridgehead hydrogen abstraction from a series of 1-substituted adamantanes by the trichloromethyl radical at 40.0°C. has been carried out. Utilizing the Hammett-Taft equation a p* value of -0.40 was obtained for this reaction. Application of the Kirkwood-Westheimer model for the transmission of substituent effects gave an...

Properties of Pseudomonas aeruginosa resistant to quaternary ammonium compound

Creator:: Washam, Clinton Jay
Abstract:: Pseudomonas aeruginosa cells were selected for their ability to grow in the presence of 750 ppm alkyldimethylethylbenzyl ammonium chloride (QAC). These cells were found to retain their resistance to the germicide throughout tri-weekly transfers for 7 months in tryptone glucose yeast extract (TGY) broth containing no QAC. Comparisons of the...

Estrogen regulation of pituitary function in the gonadectomized sheep

Creator:: Cooper, Gordon Jay
Abstract:: A total of five individual experiments were conducted with gonadectomized, male sheep to study the influence of estrogen on the plasma level of pituitary activities, with the greatest emphasis given to gonadotropic activity. Estrogen treatments employed were as follows: 1. 12 mg. diethylstilbestrol (DES) implanted subcutaneously. 2. 1 mg. DES...

Contracting nucleolar vacuoles in somatic tobacco cells growing in microcultures

Creator:: Johnson, John Morris
Abstract:: Contracting nucleolar vacuoles are a general and consistent feature of somatic tobacco cells growing in microcultures. Nucleolar vacuoles were studied in cells from callus tissues of two single-cell clones, H-196 and H-239, of hybrid tobacco (Nicotiana tabacum X N. glutinosa). Vacuoles periodically contracted either completely or incompletely, apparently releasing a...

Hydrogen abstraction from substituted t-butylbenzenes

Creator:: Harvey, Robert Louis
Abstract:: A study of the relative rates of the alkyl hydrogen abstraction from a series of meta and para substituted t-butylbenzenes by the chlorine atom at 70°C has been carried out. Application of the Hammett equation yielded a ρ value of -0.44 for the para compounds. Possible explanations for the non-linearity...

Steric effects in free-radical hydrogen atom abstraction reactions

Creator:: Totherow, William D.
Abstract:: A study of the relative rates of benzylic hydrogen abstractions from a series of meta and para substituted neopentylbenzenes by the bromine radical and trichloromethyl radical at 70°C has been carried out. Application of the Hammett equation yields p values of -0.75 for the bromine atom and -0.94 for the...

Determination of intake and digestibility of pasture forages using conventional and indicator techniques

Creator:: Alpan, Suleyman Orhan
Abstract:: Digestibility experiments were carried out with dairy heifers to determine the digestibility of orchard grass, Dactylis glomerata, and also to evaluate the accuracy of various indicator techniques in pasture digestibility experiments. Chromic oxide was used as an external indicator to predict fecal dry matter output in three digestion trials. Cut...
