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....
About 7,000 years ago two major tephra-falls blanketed the
Pacific Northwest in volcanic ash. These two tephra-falls, identified
as the Llao and climatic tephra-falls, were a part of the eruptive
events that led up to the collapse of Mount Mazama to form Crater Lake
in the southern Oregon Cascades.
The...
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...
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...
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...
