This essay seeks to analyze the wind-power policies of Spain, the United States and the
world in order to better understand the past, present and future potentials of the resource.
The growing demand for energy, concerns about global warming, and the need for
increased energy security encourage societies to embrace...
Organophosphate insecticides may produce sublethal, adverse effects on salmonid
growth, reproduction, maturation, swimming, and feeding. Chlorpyrifos, an
organophosphate insecticide, was detected by the Oregon Department of Environmental
Quality in the Hood River and tributaries during March 1999 at levels exceeding state
water quality standards in the range of 0.011-0.482 μg/L....
Water is one of the primary wants of
human life no less essential than air and food hence
the strong and religious interest that has been
attached to the means of its supply. In the earliest
records of civilization we read of the digging of
wells and building of water...
Volatile organic compounds (VOCs) play an integral role in climate change and as a carbon source for organisms living in a marine environment. These compounds have many sources, but the impacts of biogenically produced VOCs is not fully known. Phaeodactylum tricornutum was studied under axenic ideal growth conditions to determine...
Winter hardiness in barley (Hordeum vulgare) is a trait targeted by breeding programs in order to expand the potential area of adaptation of fall-sown cereals. Vernalization requirement is an important factor in winter hardiness. A vernalization requirement is an extended period of low temperature required for transition from the vegetative...
The Mount Thompson 7.5 Minute Quadrangle is located in the central Boulder Batholith, between the cities of Butte and Helena. The Boulder batholith is host to numerous metalliferous vein deposits, including those in the Butte District. Recent USGS (EDMAP)-funded geologic mapping at 1:24,000 scale in the Mount Thompson Quadrangle during...
Due to public and regulatory restrictions, genetic containment technology is critical for research and development of transgenic trees in forestry. A multi-year field trial demonstrated that the RNAi-LFY construct successfully induces sexual sterility in 6K10 poplar (Populus alba) without visible effects on vegetative development. However, its limited number of replicates...
The electrical properties of amorphous and crystalline titanium dioxide polymorphs are reported. Titanium dioxide is a widely used transparent semiconductor and it is a useful oxide model. Using variable temperature transport measurements of thin films, it was possible to establish the activation energy barrier for conduction. This was accomplished using...
There is a growing need to establish alternative approaches for assessing hazard from chemical exposure compared to the traditional method of animal testing. Approaches that relate chemical structure to biological activity are gaining acceptance in the field as in silico methods for characterizing and predicting chemical toxicity. In this study,...
Brownian motion is the movement of a particle in a fluid resulting from collisions with surrounding molecules. It has modern applications in simulating fluid dynamics and the motion of proteins in biophysics. Brownian motion simulations generally evolve the initial state by applying Newton’s second law to every particle. These simulations...
Diet History Questionnaires (DHQ) can only provide general information about a person’s nutritional intake. It is unable to cluster groups of people based on diets or lifestyles, nor identify specific foods that may play a role in disease prevention. The aim of this study was to validate the use of...
Microbial electrolysis cells (MECs) for hydrogen production exhibit great advantages over many other biohydrogen production techniques in terms of versatility of substrate and hydrogen yield. However, hydrogen scavenging by methanogens put forward a great challenge to the application of the single chamber MECs when using mixed culture. Various strategies were...
Various mollusks, including small bivalves and gastropod snails, are a common food source for intertidal crabs. Prey opening techniques used on hard-shell prey are dependent on claw size and morphology. For example, large, strong claws can crush a snail outright while smaller, weaker claws leave characteristic peels, pulls and upper...
Studies were conducted to assess influencing the effectiveness of sheep for grazing control of false brome (Brachypodium sylvaticum) an invasive grass species. Orphan lambs were exposed to false brome via grass extract in their milk and naturally reared lambs were exposed by grazing dense stands of false brome with their...
Postpartum uterine inflammation (endometritis) is not uncommon in beef cattle, resulting in infertility and culling. Prolonged calving may contribute to the increased incidence of endometritis in heifers. Commonly used methods to treat endometritis in beef cattle include intrauterine antibiotics and/or hormone injections, which can result in meat residues. Platelet rich...
