Because of their potential for adversely affecting aquatic resources, increased rates of
erosion and sedimentation associated with low-volume forest roads have recently gained the
attention of land managers in the Pacific Northwest. For example, on the Tongass National
Forest in Southeast Alaska, there is an urgent need to explore the...
Ocean deoxygenation is predicted to increase in severity over the next few decades, posing a threat to marine life and fishing economies. Improved predictions of ocean deoxygenation depend on a better understanding of the biogeochemical mechanisms that underly this process. Within the realm of biogeochemical mechanisms, this project specifically investigated...
Atmospheric fine particulate matter (PM2.5) has been linked to the death of 7 million people per year around the planet. The organic portion of PM2.5 is responsible for increases in oxidative stress, inflammation, mutation and carcinogenesis. Anthropogenic activity releases more organic material into the atmosphere, and has increased the amount...

echoed within the Republic of South Africa and around the
world, showing that racial tensions in that country were
severe. At his death he was a hero to the black...
Phospholipids of Tenebrio molitor larvae were
separated on columns of DEAE-cellulose and silicic acid-Hyflo Super Cel. The major phosphatide components were
identified by various analytical procedures.
Phosphatidyl choline was demonstrated to be the
predominant phospholipid with a high percentage of
phosphatidyl ethanolamine. A small amount of inositol-containing
phosphatides were present....
Traditional readings of George Bernard Shaw's texts suggest that he is not a pure
Marxist socialist because of the spiritual and nationalist aspects of his vision. This thesis
attempts to confront Shaw's politics in order to demonstrate that he indeed offers a viable
socialist program. Overlaying his socialism with Louis...
Deburring of machined parts is a crucial task in the aerospace and automotive industry. This process is still performed manually to a large extent due to the unpredictability of burr formation as well as the complex interactions between the human arm and the workpiece. Poor ergonomics, repetitive stress and strain...
This study assessed the differences between
teachers' opinions and students' responses regarding the
influence of clothing on adolescents' decisions to
participate in social activities.
Survey methodology was used with the final samples
consisting of 336 students and 140 teachers who were drawn
from six high schools located in economically depressed...
Models of ecosystem carbon (C) balance generally assume a strong relationship between net primary productivity (NPP), litter inputs, and soil C accumulation, but there is little direct evidence for such a coupled relationship. Using a unique 50-year detrital manipulation experiment in a in a mixed deciduous forest and restored prairie...
