Four different plot types were established in shrub and tree comunitities in Little Elk Valley in southwest Oregon. Ten functional (F) plots were cleared of all vegetation in a radius of three times the height of the surrounding vegetation around a single Pacific madrone (Arbutus menziesii Pursh.) tree. Ten competition...
This investigation was designed to study the possible effects of
the electrical stimulation of beef muscle on microorganisms present on
the meat surface during and after treatment. The effect of electric
current on microorganisms in minimal media suspension was also studied.
Cell viability before and after electrical treatment or exposure...
Experimental work at the 1982 Dry Deposition Intercomparison
Experiment (DDIEx) involved the use of optical particle counters for
covariance estimates of dry deposition velocities of accumulation mode
aerosols. Meteorological and particle flux observations are
presented. Deposition velocity estimates exhibit scatter about zero.
A formulation of the standard error of the...
In their modern context questions of heredity have come to be
closely aligned with theories of evolution because all such theories
require the presence of heritable variation. Thus the need for an
understanding of a source of variation and a mechanism for its inheritance
became very apparent with the general...
The general problem of classroom scheduling is well known to be NP-complete. A typical classroom scheduling problem is that of assigning students to a limited number of pieces of laboratory equipment. Frequently several identical pieces of equipment are available only at fixed hours and have limited access due to physical...
A special case of a parallel multiprocessor scheduling (MP) problem
is investigated. A set of jobs with a known process time and a.resource
requirement is scheduled on machines controlled by processors,and
the total changeover cost between jobs is to be minimized. Each processor
may control up to two machines and...
Compaction of a horizontal microprogram is an attempt to
exploit fully the parallelism permitted by a given algorithm and data
processing structure in order to produce a short microprogram. B oth
viewpoints of the problem: the local compaction viewpoint which
deals with compaction within a straight-line segment, or a basic...
The black grass bug genus Irbisia Reuter was revised. Over 18,000
specimens were examined and information concerning the biology, host
plant and distributional relationships of the species was compiled.
In addition to external characters, the male claspers and vesica, and
the female dorsal libiate plate of the bursa copulatrix and...
The primary goal of the study was to determine if and
how baseball players discriminate the rotational direction
of an approaching pitch during the first 200 milliseconds
of the flight of the ball. In addition, college-level
baseball coaches were surveyed to assess the level of
agreement between coaches relative to...
