The problem of heat transfer due to free convection in a channel formed
by two parallel, isoflux, vertical plates is of considerable importance in electronic
cooling applications, thermosiphons, the optimum spacing of plates or components,
industrial stacks, heat exchangers, nuclear power plants and combustion involving
vertical walls. Although in each...
The effect of different soil moisture levels on the amount and
location of NO₃ -N accumulation in the soil profile were studied.
The cultivars used in this study were Mcdermid, a soft white
winter wheat, and Hudson, a medium early winter barley.
Moisture treatments simulating dry, normal and wet fallow...
At the College of Engineering, Oregon State University, we have successfully developed and demonstrated a distance learning application utilizing emerging communications technologies in a new way to allow control engineering teaching laboratories to be accessed remotely. Second Best to Being There (SBBT) provides the remote user with all the capabilities...
An important issue in engineering education is the availability of laboratory resources for student use. Using a computer network to link geographically distant students with laboratory teaching resources makes expensive and innovative equipment available to more students. At Oregon State University, we provide a working environment where remotely-located students can...
Carbonatable calcium silicate cement (CSC) is a promising approach to reduce the carbon footprint associated with concrete production. Carbonatable CSC gains strength by reacting with carbon dioxide (CO2). While the concept of carbonation is well known, more information on the curing process is needed. This study focuses on studying the...
Distance learning enables students to study effectively from remote locations. With
televised lectures now commonplace, many disciplines can provide effective distance
learning. While the lecture format serves many disciplines, it does not serve those that
require laboratory work. Currently, there is little distance learning support for laboratory
work.
Second Best...
The semi-arid dryland wheat-producing areas of the Pacific Northwest are characterized by cool, moist winters and dry, hot summers. The amount of annual precipitation is generally quite variable and inadequate for annual cropping. Where soil depth is adequate, the predominant loessal soils generally supply sufficient moisture for small grain production...
A study of precipitation and yield levels in fallow-wheat rotations at three
Pacific Northwest locations demonstrated that in the Columbia Plateau region,
the variability and skewness of precipitation increased with decreasing mean
amounts of precipitation. The seasonal distribution of precipitation had a
marked effect on wheat yield. Comparisons of precipitation...
Dryland winter wheat in eastern Oregon is usually subjected to
water stress several times during the growing period. Moreover, the
last three months of growth period depend strongly on the available
soil water. The fertility level, stage of growth, availability of
soil water and climatic conditions all interact to determine...
In recent years, multiple historic and contemporary timber buildings have been instrumented with sensors to monitor the performance of wood products and novel engineering systems. While literature states the potential of structural health monitoring (SHM) data to inform decision-making process of key stakeholders in the architects, engineers, contractors and manufacturers...
