Random processes are monitored over space and time by a network of stations distributed across a spatial region. Researchers have developed several analysis techniques to model the random process. Some of them require assumptions on the spatio-temporal variability of the process. An alternative method to analyze spatio-temporal data that does...
Wine grape pomace (WGP), the byproduct from winemaking, is a good source of polyphenols and dietary fibers, and may be utilized as antioxidant dietary fibers (ADF) for food applications. The objectives of this thesis research were to first determine the phenolic compounds, antioxidant and antimicrobial activities in red WGP under...
The importance of accurately identifying inventories of domestic energy, including forest biomass, has increasingly become a priority of the US government and its citizens as the cost of fossil fuels has risen. It is useful to identify which of these resources can be processed and transported at the lowest cost...
Reported here is an investigation to determine if azinphos-methyl (AZM), an
organophosphate insecticide, adducts to hemoglobin, and if so, whether the
hemoglobin adduct could be used as a quantitative marker of occupational AZM
exposure. We hypothesized that AZM, or a metabolite of AZM, binds to hemoglobin
in erythrocytes forming an...
Drought is expected to increase in many parts of the world and has been shown to affect tree physiology and growth, with seedlings being particularly vulnerable. Seedling drought responses are often species dependent, and even within species different populations may demonstrate a spectrum of responses to drought, from susceptibility to...
Oregon white oak, or Garry oak (Quercus garryana), has been adversely affected by land-use conversion, landscape fragmentation, and anthropogenic fire suppression. Its historical range has contracted significantly to the point where an estimated 1-5% remains intact. Natural regeneration is difficult due to a lack of seed sources and the physiological...
Currently, the only anthrax vaccine licensed for human use in the United States is the Anthrax-vaccine-absorbed (AVA or Biothrax®). AVA suffers from several drawbacks, including a complicated and lengthy dosing schedule that requires six initial injections administered over eighteen months, followed by annual boosters. Therefore, a new generation anthrax vaccine...
The inter-relationships among δ¹³C and δ¹⁸O in tree ring cellulose and ring width have the potential to illuminate long-term physiological and environmental information in forest stands that have not been monitored. We examine how within-stand competition and environmental gradients affect ring widths and the stable isotopes of cellulose. We utilize...
The hyporheic zone is of great interest for stream ecologists because of its role in stream biogeochemical processing. Our study addresses the effects of leaf-litter inputs and varying discharge on surface–hyporheic water exchange and their possible consequences for the hyporheic zone biogeochemistry. Our study was conducted during autumn in Riera...
Background: Supernumerary chromosomes have been found in many organisms. In fungi, these “accessory” or “dispensable” chromosomes are present at different frequencies in populations and are usually characterized by higher repetitive DNA content and lower gene density when compared to the core chromosomes. In the reference strain of the wheat pathogen,...
