This report is a critique of a study by the U.S. Environmental Protection Agency that found a statistically significant correlation between the application of the herbicide 2,4,5-T (dioxin) and miscarriages in the Alsea watershed. "If there is a relationship between herbicide use and miscarriages in the 'Alsea Basin' and its...
A numerical technique is presented for solving the gas dynamics
of a pulsating combustor. The computer solution which is developed
follows directly from the fundamental conservation laws applied to
discrete volumes rather than attempting either to finite difference the
resulting partial differential equations, or to apply the Method of Characteristics....
The reproductive characteristics of the mountain cottontail
rabbit, Sylvilagus nuttalli (Bachman), were investigated from 269
specimens collected in central Oregon between 28 May 1968 and
28 August 1969.
Male rabbits were in breeding condition between mid-February
and 3 July 1969. Nearly 77% of the females bore four litters between
7...
Air temperatures and soil temperatures at the surface, two inches,
and four inches under a grass cover were recorded over a 93 day period.
These data were used along with other temperature data from bare soil
in the construction of three sets of models for the prediction of
maximum and...
The roles of fabrics in subdrains are identified for normal
groundwater flow conditions to determine hydraulic and pore characteristics
necessary for design considerations. Two conditions are discussed:
(1) the fabric in direct contact with the soil to provide
mechanical support, and (2) the fabric as a filter to remove soil...
Clinical methods to diagnose specific organ dysfunction have not been evaluated in fishes. To determine if an accepted clinical test of mammalian liver function could be applied to fishes, the
hepatic disposition of the organic anion sulfobromophthalein (BSP) was studied in rainbow trout (Salmo gairdneri) treated with a model hepatotoxicant....
