The current method of determining component failure rates
for probabilistic risk assessment (PRA) in the nuclear
industry is to take the total number of failures divided by
the time over which the failures occurred. The method
proposed in this study is the reliability growth method and
involves taking into account...
In the field of nutrition, complex carbohydrates have
become increasingly important in the last decade. The fiber
fraction of foods has been implicated as modifying the
etiology of several chronic diseases and the starch fraction
is important with respect to the glycemic index of foods.
This study has focused on...
I studied species' abundances and habitat relationships
of breeding and winter birds in commercially thinned and
unthinned Douglas-fir (Pseudotsuga menziesii) stands from May
1989 to June 1991. The study was conducted in 40- to 55-year old
stands in the Central Oregon Coast Ranges and the
Tillamook State Forest. Total abundance...
Index selection provides an efficient means of conducting selection on multiple traits by combining information on economic value,
heritability, and the genetic and phenotypic correlations between traits to improve overall merit. The use of this method in forestry has been hampered by the lack of knowledge of the relative importance...
Detection and treatment of bacterial kidney disease (BKD)
was investigated. Experiments were conducted to evaluate the
quantitative, fluorescent antibody technique (QFAT) that is used
to detect, identify, and quantify both typical and 'bar form'
Renibacterium salmoninarum cells. Smears of kidney tissue from
naturally and artificially infected salmonids, both with and...
Public agencies need information on the value of
recreational activities to assist in managing fish and
wildlife species. Over the past two decades economists have
developed and applied techniques to measure the value of such
non-marketed commodities.
The contingent valuation method (CVM) is one technique
used by economists to measure...
Conventional stainless steel - water and ceramic fabric composite water
heat pipes have been built and tested. The tests have been conducted to compare
the performance characteristics between conventional and fabric composite heat
pipe radiators for space nuclear power heat rejection systems. The fabric
composite concept combines a strong ceramic...
A pilot study was conducted to evaluate whether premenstrual syndrome was a risk factor for breast cancer among premenopausal women. As subjects, 54 women between the ages of 26 and 46 years, each diagnosed with breast cancer, were compared to three separate control groups, consisting of 193 female patients seen...
