Selenium deficiency in rats results in increased carbon metabolism,
approaching twice the rate of selenium supplemented animals
(normal). This is also reflected in a 50 percent increase in lysosomal
enzyme activity in tissues of selenium deficient animals.
Isolation of rat liver lysosomes shows a 17 percent increase in
membrane thickness...
In order to assess the importance of RNA synthesis in the induction
and antibody-producing phases of immune responses, actinomycin
D was used to inhibit the primary and secondary in vitro immune
responses of mouse spleen cells against heterologous erythrocytes.
The presence of actinomycin D (0.1 or 0.125 μg /ml) throughout...
This study compares production rates and costs for four ground skidding machines and for four harvesting treatments. The four
machine types studied were a Caterpillar 060 crawler (060), Caterpillar 518 rubber tired skidder (RTS), FMC 200 CA (FMC), and
International TD-8E crawler (TD-8E). Two treatments, conventional/whole tree and designated/tree length,...
Workable log grading systems are needed as aids to marketing timber and other phases of forest management. How can on system be evaluated and compared with other systems. The question of comparisons arose soon after the Western Pine Section of the Forest Service's National Log Grade Project was established in...
Sixteen species of oceanic shrimps, seven Penaeidea and nine Caridea, appeared in 244 collections made within the upper 1500 m at one station in the northeast Pacific off Oregon. Most of the species were primarily mesopelagic in distribution. The most abundant species, Sergestes similis, was the only shrimp common in...
Understanding the local context that shapes collective response to wildfire risk continues to be a challenge for scientists and policymakers. This study utilizes and expands on a conceptual approach for understanding adaptive capacity to wildfire in a comparison of 18 past case studies. The intent is to determine whether comparison...
The presence of low-lying stratocumulus clouds and fog has been known to modify biophysical and ecological properties in coastal California where forests are frequently shaded by low-lying clouds or immersed in fog during otherwise warm and dry summer months. Summer fog and stratus can ameliorate summer drought stress and enhance...

In recent years, economists have started to move beyond calculating regulatory effects on a pollutant-by-pollutant basis since their interaction is important. In this study, we take up this issue. To allow for joint production of multiple pollutants and marketable output, we specify our technology using a directional distance function. This...
