Porous carbon is indispensable in modern technology applications. It is used for energy storage, gas separation, water purification, catalyst support, and chromatography. The diversity of its applications stems from its unique properties, including high specific surface area, tunable pore volume, and chemical stability. Specifically, the large surface area provides high...
Landslides are a pervasive hazard that can result in substantial damage to properties and loss of life throughout the world. To understand the nature and scope of the hazard, landslide hazard mapping has been an area of intense research by identifying areas most susceptible to landslides in order to mitigate...
Purpose of the Study:
The purpose of this research was to study the school districts
in Umatilla County as they existed in 1962-3 and to formulate a
guide for reorganization of these districts into sound efficient units.
The following sub-factors were considered essential to this research,
and were dealt with...
Temporal variations in individual spectrum lines
emitted by a microwave discharge in pure helium are
investigated: The discharge is produced in a quartz tube
located inside of a section of waveguide which carries
pulsed 3 centimeter microwaves. The helium used is purified by a three-fold process consisting of treatment with...
Sheep and cattle dietary preferences were determined on tall fescue-subclover ( Festuca arundinacea-Trifolium subterraneum) and
perennial ryegrass-subclover (Lolium perenne-Trifoliuni subterraneum)
pastures in western Oregon during the spring and summer periods
of 1964 and 1965. Esophageal-fistulated Willamette ewes and
Hereford and Hereford-Angus yearling cattle were grazed separately
on each pasture mixture...
The purpose of this study was to investigate the practices of
curriculum development in the community colleges of the western
states and make recommendations for guidelines that can be used to
plan, implement, and evaluate technical vocational programs in the
community colleges. The various functions of other organizations
concerned with...
The genus Phytophthora contains some of the most destructive pathogens of forest trees, including the most destructive pathogen of alder in recent times, Phytophthora alni. Alder trees were reported to be suffering from canopy dieback in riparian ecosystems in western Oregon, which prompted a survey of alder health and monitoring...
The developmental patterns of five fuel resources located within
the state of Wyoming are examined through time and in relation to
several factors external to the location of the fuels. An historic
description and inventory of the five fuels: petroleum; natural gas;
oil shale; coal; uranium are presented. External factors...
Kinetics of cell division in the intestinal epithelial proliferative cells (cell nests) of the rough-skinned newt, Taricha granulosa, were studied using tritiated thymidine autoradiography and the mitotic arresting properties of colcemid. Percent labeled mitoses (PLM) curves were drawn from the autoradiographic data from two separate experiments in which the newts...
