Improving crop cultivars for use on organic farms is pertinent, as current elite germplasm is less resilient within the more variable context of organic farm environments. Although a growing number of studies have focused on organic plant breeding in cereal crops, very few have focused on vegetable crops, especially those...
A model of acute glutamate- and domoate-induced toxicity was developed and characterized in cultured rat cerebellar granule cells (CGCs) using experimental conditions which preserve the voltage-dependency of NMDA receptor function. Glutamate, which is normally non-toxic to CGCs in physiologic media (pH 7.4), was shown to induce a cytotoxic response after...
Ecosystems are facing increasing threats from human related activities, such as overfishing, pollution, habitat destruction, species invasions, and diseases, among others. While oceanic islands provide natural laboratories to understand ecological and evolutionary process, they are also particularly vulnerable to these impacts, given their usual isolation from the mainland and the...
Work-related hazards and exposures affect human health and well-being. Occupational Safety and Health (OSH) surveillance is fundamental to the public health approach. OSH surveillance provides important data on the occurrence and magnitude of the problem and risk/protective factors. A wide variety of OSH surveillance programs and systems have been established...
This research design was based upon the mutual relevance
between the fields of education and anthropology to cause cognitive
cultural awareness by the teachers of adults as well as visibility
within the Mexican American ethnic group.
Specifically the purpose of this study was twofold:. (1) to
determine whether the adult...
From 5 April – 21 September 2012 we monitored the distribution, abundance and productivity of the federally Threatened Western Snowy Plover (Charadrius nivosus nivosus) along the Oregon coast. From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North Tahkenitch Creek,...
Rapid rates of biodiversity loss have supported the notion that Earth is experiencing a sixth major extinction event. The causes of worldwide biodiversity loss are multifaceted and context dependent. One of the most prominent groups experiencing population declines and extinctions are amphibians. Several pathogens and their associated diseases are especially...
This research applies the biologically inspired, artificial evolutionary processes of Genetic Algorithms and Genetic Programming to digital hardware circuit synthesis and minimization. In this new application, three approaches are taken to genetic hardware development. First, as a method for logic synthesis, Genetic Programming is applied to the building of logic...
The principle purpose of this study was to determine
the effectiveness of human relations-sensitivity training on
the self concept of low income high school students. The
sample group consisted of 47 low income high school students
attending the 1978 Summer Upward Bound program at Oregon
State University. Participants were randomly...
