There is much interest in the State of Vermont in cable harvesting. Since there are no time studies available for cable harvesting with various machines in Vermont, it is necessary to arrive at production and cost levels by a different method.
The method chosen for this paper is made up...
Establishment of a non-native plant species in new habitats beyond their native range is associated with inherent changes in ecosystem properties. These changes may be dramatic or subdued, and consequences may be positive or negative depending on characteristics and response of the resident ecosystem. Non-native aquatic plant species in the...
Coastal marsh vegetation is an important component in maintaining marsh stability that is threatened by changes in sedimentation, sea level rise, natural and anthropogenic disturbances, and competition from invasive species. Vegetation has been demonstrated to reduce wave energy, increase sedimentation, and decrease erosion in tidal environments under a range of...
Local adaptation in plants may hold the key to understanding the level of resilience of an ecosystem and probability of persistence of a species in the face of rapid anthropogenic changes in climate and disturbance regime. Clonal species are especially important in wetlands, one of our most productive and vulnerable...
The popularity of gravity-return skyline logging systems is now increasing in the Western United States. Simplicity seems to be the basis for their success. While two drum yarders are most commonly used, ·some systems, such as the Wyssen, use only a single drum for yarding. Carriages commonly used with these...
Streptococcus gordonii is a bacterial species that naturally colonizes the oral cavity of most healthy humans. It resides in the mouth as an adherent to dental surfaces and, with few exceptions, does not cause disease in individuals it inhabits. It possesses qualities that encourage its use as a vector to...
This thesis is an engineering report on the creep behavior of
power transmission line conductors. Laboratory creep test results
are reported for Pheasant, Narcissus and Chukar conductors.
The report follows a standard nomenclature and format suggested
by the International Study Committee No. 6 of Conference
