There are well over 200 species of fishes which are known to be venomous, and which are capable of inflicting serious and
potentially fatal wounds. Within this group, less than 5% have been studied even in the most preliminary manner and, to date, the
basic chemical structure of even a...
The desire to understand the spatial and temporal drivers of animal behavior and distribution relative to scale is central to movement ecology. Optimal foraging theory states that a predator should continue exploiting a patch until it is no longer profitable to do so. As human developments increasingly encroach on the...
Low temperature combustion (LTC) engines offer improved efficiency and reduced emissions over traditional gasoline spark-ignited and diesel compression-ignition engines. The ability to produce fuels optimized for LTC engines could help increase efficiency and therefore improve fuel economy, insomuch that Federal fuel economy standards could be met. Currently, a fuel performance...
The influence of atmospheric humidity and free water on germination and germ tube growth of Botrytis cinerea Pers. ex Fr. was studied. Relative humidities (RH) were maintained inside insulated humidity chambers with sulfuric acid solutions of the appropriate concentrations. Insulation was necessary to reduce the incidence of condensation caused by...
This thesis covers the efforts of the design, analysis,
characteristics, and construction of a Linear Brush less Doubly-Fed
Machine (LBDFM), as well as the results of the investigations and
comparison with its actual prototype.
In recent years, attempts to develop new means of high-speed,
efficient transportation have led to considerable...
The Oregon Dunes National Recreation Area is managed by the Siuslaw
Forest division of the United States Forest Service (USFS). This area has gradually been
overcome by vegetation since the 1950's, originating with the exotic European Beach
Grass (Ammophila arenaria). The invasion of this exotic vegetation has resulted in a...
Floodplains are a significant and increasingly threatened ecosystem. As restoration projects are implemented more frequently in degraded floodplains, novel methods are emerging with a focus on restoring critical processes in which vegetation plays a key role. The purpose of this paper is two-fold: 1) to develop expectations for vegetation response,...
A significant source of energy consumption comes from maintaining desired indoor environment conditions in warehouses and other industrial facilities. In efforts to combat the raising energy costs, studies into more efficient heating and cooling strategies has been a topic of consideration for a number of years. One of the areas...
