Since 1984, the city of Cannon Beach has used a 7 ha, two-cell red
alder/twinberry/slough sedge palustrine wetland to treat chlorinated
effluent from a four-cell aerated/facultative lagoon system. For
three years effluent has met summer wastewater discharge limitations
(10 mg/L BOD5 and 10 mg/L TSS). Field research in 1986 concerned...
The American philosopher and literary critic Kenneth Burke was an "ideologist" (although he never called himself this, and added to that, he spent most of his life avoiding the Marxist term of ideology to describe human "systems" of ideas). Burke instead used the terms "orientation," "rationalization," "perspective." "critical perspective," "way...
T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...
This study of Oregon secondary school teachers was designed
to find why individuals had chosen this particular career, what
they think of their positions, what time of their lives they chose
teaching as a career, and what their career plans are for the
future. The respondents were full-time Oregon secondary...
The decision to bury high level nuclear wastes in deep geological formations
led to the study of the Hanford Nuclear Reservation as one of three possible sites for
the first nuclear waste repository in the United States. To adequately evaluate the
environmental impact of siting nuclear waste repositories in basalt...
The immune system has been identified as a very sensitive target for the toxic effects of 2,3,7,S-tetrachlorodibenzo-p-dioxin (TCDD). Exposure to TCDD has been shown to disrupt the generation of both cell-mediated and humoral T cell-dependent immunity in laboratory animals; however, the mechanism remains unknown. In this dissertation, the hypothesis is...
In the problem of testing the median using a random sample from a
certain distribution, and if no other parametric family is suggested,
the t-test is known to be the optimal procedure when this distribution
is normal. If the sample appears to be non-normal, one has the choice
either to...
