Synthesis of a model of the spiroketal portion of avermectin B

Creator:

Warrier, Ulhas S.

Abstract:

Avermectin Bia is a member of a class of medicinally important natural products known for its potent antiparasitic activity and interesting structural features. In this thesis, synthesis of a model for the spiroketal portion of the avermectins is presented. Oxidation of (S)-2-methylbutanol, followed by a stereoselective chromium mediated reaction with...

The effect of temperature on biochemical activities of embryo and seedling of germinating rice (Oryza Sativa L.) seed

Creator:

Luo, Shun

Abstract:

Some biochemical activities in embryo or seedling of germinating rice (Oryza Sativa L.) seed were studied to explain the effects of suboptimum (20 C), optimum (30 C), and supraoptimum (40 C) temperatures on seed germination and seedling growth. It was observed that 40 C slightly speeded up seed germination but...

Balanced structural cross section of the western Salt Range and Potwar Plateau, Pakistan : deformation near the strike-slip terminus of an overthrust sheet

Creator:

Leathers, Michael R.

Abstract:

The Salt Range and Potwar Plateau of northern Pakistan are part of the thin-skinned, active thrust system related to the ongoing collision of the Asian and Indian continental blocks. Platform rocks and orogenic molasse of the Indo-Pakistani shield are deformed in south-verging thrusts and folds, relative to a northward-converging basement....

Behavioral and demographic characteristics of northern sea lion rookeries

Creator:

Merrick, Richard L.

Abstract:

Northern sea lions (Eumetopias lubatus) were studied at three sites (Rogue Reef, Oregon, Marmot Island, Alaska, and T.Ugamak Island, Alaska) during the 1982, 1983, 1985, and 1986 breeding seasons. Data were collected on female activity budgets, attendance patterns, births, copulations, population structure, and patterns of seasonal and daily abundance. Females...
