The reduction in mechanical load imparted on the body during spaceflight presents unique physiological challenges. One detrimental and seemingly unavoidable response to microgravity is rapid bone loss. This adaptation is hazardous not only to astronaut health, but to the success of long-duration exploration-class missions. Skeletal adaptation to spaceflight in astronauts...
The topic of this study is the cultural impact of the computer in a school. "Impact" is 'defined as the cultural consequences of intended and unintended learning that occur when computers are used in the school. The major theoretical orientations of the work include the concepts of manifest and latent...
In this dissertation, I posited the need to understand how an invented community (the Society for Creative Anachronism) constructs symbolic meaning in material objects and value systems. Using ethnographic methods, I focused on the Knights and their regalia as this is the most widely accepted material symbolism. People go to...
Studies were conducted from 1962 to 1966 to investigate the
effectiveness of several practices in manipulating medusahead
(Taeniatherum asperum (Sim. ) Nevski) infested and/or dominated
ecosystems by releasing competition in favor of perennial grasses.
Several herbicide treatments were evaluated for selective
control of medusahead and cheatgrass (Bromus tectorum L. )...
Alcohol is a widely consumed, nonessential, bioactive nutrient with end-organ effects on the skeleton. Moderate levels of alcohol consumption are generally associated with increased bone mineral density (BMD), whereas higher intake levels result in reduced bone formation, bone loss, and increased risk for osteoporotic fracture. Given the negative impact of...
Estimates of potential carbon (C) storage can be used to constrain predictions of future carbon sequestration and to understand the degree to which disturbances, both natural aid anthropogenic, affect C storage. An upper bound on C storage in the Pacific Northwest (PNW) of the United States was estimated using field...
The central purpose of this study was to examine the
attitudes of non-disabled college students toward their
developmentally disabled peers attending the same college.
Specifically, it examined the attitudes of non-disabled
students toward the developmentally disabled students in the
Transitional/Vocational Program the Fairview campus of
Fairview College, Alberta, Canada.
Objectives...
Emissions largely associated with the combustion of fossil fuels and agriculture has caused elevated atmospheric deposition of nitrogen (N) and sulfur (S) throughout much of the developed world. Increased atmospheric deposition of N and S can lead to soil and surface water acidification and affect forest soil nutrient supply. The...
