The development of bovine embryos following enzymatic removal of the zona pellucida
(1980)
This study to determine the survival of bovine embryos with and without the zona pellucida was divided into two parts. The first part consisted of removing the zona pellucida with a .5% pronase solution from half of the ...
Factors determining ion exchange selectivity : I. Aqueous K+-H+ exchange with [alpha]-zirconium phosphate. II. Gas-solid ion exchange reactions
(1980)
The heats of K^+ - H^+ exchange have been measured calorimetrically on three samples of zirconium phosphate of widely differing crystallinity. The more crystalline exchangers both exhibit exothermic reaction over the full ...
New synthetic reactions of enolates of [alpha]-amino acid derivatives
(1980)
Hydroxyalkylation and acylation reactions of lithium enolates of amino acid derivatives 11-13 were investigated. Extensive rearrangement of 11 occurred under the reaction conditions. The lithium enolate of 12 exhibited ...
Cognitive style as indicated by self-report, physiological, and performance representations of hemisphericity
(1980)
The purpose of this study was to examine the relationship of self-reported cognitive mode, as an indicator of brain hemisphericity, with physiological indicators of brain hemisphericity and task performance on seven ...
