Nuclear techniques such as perturbed angular correlation (PAC) sample the hyperfine interactions of a large number of probe atoms in specific crystallographic sites. Real crystals contain static defects producing a distribution of electric field gradients (EFGs) that add to the ideal EFG of the crystal at any given probe site....
The major objectives of this study were an
evaluation of the Meteorological Office Rainfall and
Evaporation Calculation System (MORECS) evapotranspiration
(ET) model using the Penman-Monteith equation and
comparison of the MORECS and measured surface resistance.
Meteorological, soil and plant parameters were measured in
an alfalfa field over two growing seasons....
The purpose of this thesis is to explain why the reservation system manifested so
disappointingly for the Native American groups of Southwest Oregon. It seeks to characterize the
struggle that raged in Southwest Oregon from 1850 to 1856 between three main groups there:
indigenous peoples, white squatters and miners, and...
Concentrated culture supernatants from strains of Vibrio
parahaemolyticus of gastroenteric origin, "suspected" V. parahaemolyticus
isolated from cases of skin infection, nonpathogenic marine
Vibrio, V. anguillarum and V. alginolyticus, were submitted to flat
gel electrophoresis, followed by the examination of the polyacrylamide
gels for total protein and enzyme patterns.

Among other mechanisms, the Chilean fishing act established a system of extraordinary fishing permits (EFP) to access the fisheries in stage of recovery or incipient stage of development. The EFP entitles its holder the right to catch during 10 years a fraction of the global annual quota. The right is...
The present article describes the changes that took place, in terms of efficiency and distributional issues, within
Chile’s central-southern pelagic fishery industry when the administrative regime evolved from controlling the
fishing effort to assigning individual fishing quotas. These changes are described through a set of indicators that
reveal variations in...
We report a decadally resolved record of atmospheric CO₂ concentration for the last 1000 years, obtained from the West Antarctic Ice Sheet (WAIS) Divide shallow ice core. The most prominent feature of the pre-industrial period is a rapid ∼7 ppm decrease of CO₂ in a span of ∼20–50 years at...
