As part of investigations to adapt a suitable grazing system in
western Oregon, this research was designed to monitor the effects of
defoliation treatments on dry matter production, forage quality,
regrowth after defoliation, and species composition of a Lolium
perenne Trifolium subterraneum pasture for three consecutive
growing seasons from 1980...
Three commercial sausage starter cultures were grown in
an internal-pH-controlled medium (PHASE 4) and in a soluble
phosphate-buffered medium. The cultures were tested by
comparing viable counts before and after freezing at -40 C
or freeze-drying and subsequent storage for 3 months in the
frozen or dried state. Strains varied...
The goal of this study was to determine if the cardiorespiratory adaptations to an eight-week circuit weight training program are better measured with a biokinetic swim-bench test versus a standard treadmill test. The working hypothesis of the study was that since standard circuit weight training programs stress the upper body...
A method is described for the determination of N-nitrosoproline
(NOPRO) in cured meat products. NOPRO was extracted with ethyl
acetate from a slurry of cured meat and water after the addition of
ammonium sulfamate and acid. This nitrosamino acid was converted
to the methyl ester and after further purification, it...
The travel cost method of deriving demand and value of recreation
does not include fixed costs of recreational durable goods purchases
or allow for supply restrictions on the number of suitable
sites available. The omission of these two real-world situations
results in derivation of demand curves which are more inelastic...
The adoption of modem agricultural technologies in Bangladesh increases
overall agricultural productivity and income primarily through the increase in cereal
crop production. It, however, impedes the productivity of several other minor crops
and fishes, widens the distribution of income between the rich and the poor, exploits
resources and obstructs the...
An understanding of the dynamics of individual tree and stand
growth, development, and structural patterns during the immature
formative years of a commercial species is essential to determine
correct thinning practices necessary to attain desired objectives.
This study compared a natural, medium-site Douglas-fir stand
and an adjacent similar stand released...
Fishery biologists and watershed management specialists have recently begun to investigate the pollutional threat posed by organic debris left in or near the forest watercourses. Oxygen content in some streams has fallen below the limits required for fish survival. The biochemical oxygen demand exerted by the debris and the reaeration...
