Improving the husbandry in the southern three-banded armadillo (Tolypeutes matacus) through gaining knowledge of its stress physiology is imperative to maintaining a healthy, zoo-housed population. Our objectives were to: 1) validate the use of fecal hormone analysis for monitoring adrenocortical activity using both an adrenocorticotropic hormone (ACTH)… (More)
Addition of AlMe3 to commercial THF solutions of RZnX (R = aryl, functionalised aryl, vinyl; X = Br, I) simultaneously promotes Schlenk equilibria (leading to competent nucleophiles) and the formation of an Al-Zn-ligand catalyst delivering 80-90% ee for Ar(1)CH(OH)Ar(2) formation from aldehydes.
Space-time codes are usually generated using a generator matrix with 2 columns and mod 4 operations for QPSK modulation with two transmit antennas. A Z<sub>4</sub> convolutional code has also been used to represent these space-time codes. Another way of representing them is to use a conventional binary convolutional code of rate 2/4. The space-time code… (More)
An improved procedure for the preparation of enamine N-oxides involving aminolysis of epoxides, chlorination, N-oxidation, and dehydrochlorination is described. Although isolated beta-chloroamine N-oxides are prone to rearrangements when isolated, these side reactions can be slowed by the presence of stabilizing organic acids. The scope and limitations of… (More)
To establish the physical basis of subjective judgements of facial appearance, two novel computer-imaging programs differing in method of preparation and presentation of 5 features of the facial soft-tissue profile of 4 faces representing 4 different classifications of dental occlusion were compared. Images of facial soft tissue of 5 features were digitized… (More)
