Sulfur-coated urea (SCU) is a slow release nitrogen fertilizer
manufactured by the Tennessee Valley Authority. Urea granules are
sprayed with molten sulfur, then holes in the sulfur coating are sealed
with a layer of wax sealant. The sulfur coatings are mixtures of
amorphous and crystalline allotropes of sulfur. Coating thickness...
The purpose of this research was to determine whether
student academic achievement in college computer science
programs in the Republic of China (ROC) could be predicted
by factors reported to be effective in US studies. The
relationship between these factors and course performance in
computer science programs was examined. Gender...
The distribution of agricultural production for
continuous consumption requires the capacity to maintain
inventories which are large relative to the rate of
utilization. As a result, the demand for inventories is a
critical element in the pricing of agricultural
commodities. A component of inventory demand, referred to
here as reservation...
This thesis focuses on the fundamental behavior of CLT floor-to-wall connections during a fire.
Cross-laminated timber (CLT) panelized structures rely on floor-to-wall connections for the load path and stability of the structure. Additionally, the fire performance of these connections is critical to prevent horizontal or vertical fire spread within these...
This report presents observations from two programs in 1975, WISP and UP-75 to study circulation off Oregon. WISP was a study of the transition between the winter and spring regimes, and UP-75 was designed to determine whether there is a poleward undercurrent along the continental slope during the upwellinq season....
A state-of-the-art radiation detection system for simultaneous spectroscopy
of beta-particles and gamma-rays has been developed. The system utilizes a triplelayer
phoswich detector and a customized Digital Pulse Processor (DPP) built in
our laboratory. The DPP board was designed to digitally capture the analog signal
pulses and, following several digital preprocessing...
During the 1400s – 1600s, spalted wood was an expensive commodity used in marquetry style artworks across primarily Germany and Italy. It fell out of favor during the Industrial Revolution, but is currently experiencing resurgence in popularity with US woodturners. How spalted wood is used, and what types of spalted...
Materials concerning ethnic and minority groups are a concern
for many curriculum leaders. Inappropriate materials perpetuate
stereotypes, in many cases due to a lack of study concerning the
information within the materials. The materials concerning Native
Americans typically presented in public school classrooms tend to
overgeneralize information about the cultural...
Foresters care about site productivity and stem quality in Douglas-fir plantations for many reasons. The profitability of forest land and the economic returns on silvicultural investments are directly related to site productivity. Thus, understanding the relationships among Douglas-fir productivity, stem form and site characteristics is important economically. My objective was...
