In recent years considerable work has been done in the development of improved logging machinery. The word improvement may bring to mind entirely new or improved systems which offer the logger greater mobility and efficient use of manpower. Logging has generally been labor intensive, however, "The need to achieve greater...
Despite a relative decline in the size of Oregon's
sheep industry, the problem of sheep depredation remains
a serious economic and environmental dilemma in need of
objective examination and innovative solutions. An investigative
report on the problem as it occurs in Benton County
can contribute to the information required to...
The annual growth rate for the Corvallis-Benton County
area has traditionally been higher than the growth rate for the
State of Oregon. Corvallis is considered to be one of the most
densely settled communities in the state. Since 1972, Corvallis
has experienced a drastic decline in the number of housing...
Copper deficiency and Mo-induced Cu deficiency are nutrition
problems of ruminant livestock in the Burns and Klamath Falls area
of Oregon. Chemical analysis of plant and soil samples was used to
survey Cu and Mo levels in forage in these areas. The objectives
were to assess the possibility of animal...
An experimental investigation was conducted for natural convection
heat transfer in an array of uniformly heated vertical cylinders
in mercury. The test section consisted of seven electrically heated
cylinders of 1.365 inch diameter and 3.825 inch heated length
arranged in an equilateral triangular pattern. In order to preclude
side flow...
Temperature and water potential effects on the growth,
transpiration, total nonstructural carbohydrate (TNC) content, and
nutrient uptake of sudangrass (Sorghum vulgare var. piper) were
investigated in laboratory experiments. The effect of nitrogen supply
on the growth and nutrient uptake at constant soil water potential was
also investigated in this study....
The well-known local adjustment algorithm for training a
threshold logic unit, TLU, is extended to a local adjustment
algorithm for training a network of TLUs Computer simulations
show that the extension is unsatisfactory.
A new logic for a committee of TLUs, called modified veto logic,
and a local adjustment algorithm...
Five newly released and two Eastern European winter wheat
cultivars were grown under five different seeding rates (80, 160,
240, 320, 400 seeds per m²). Four of these newly released cultivars
were grown at three different locations which have different environmental
conditions. Data were obtained on grain yield, tiller number...
