The 2004 Indian Ocean tsunami raised concern among marine park managers and
hazard mitigation professionals about the significant impact of major coastal hazards
on marine park natural resources and ecosystems. The main reason for this concern is
the strong linkage of marine parks and their rich assortment of ecosystem services...
Floods are the most frequent and damaging of all types of natural disasters and annually affect the lives of millions all over the globe. However, researchers seem to have overlooked the fact that floods do not recognize national boundaries. Therefore, the phenomena of shared, or transboundary floods occurring in international...
Glutathione (GSH) is the predominant low molecular weight thiol antioxidant
in liver tissue. GSH plays an important role in maintaining the intracellular thiol redox
ratio as well as detoxification of electrophiles and xenobiotics. Aging leads to a significant decline (35%; P ≤ 0.05) in hepatocellular GSH levels. Using young (2-4...
The emerging field of regenerative medicine is mainly approached by two different aspects. First is the use of stem cell based models to generate a suite of differentiated cells for therapeutic applications and the alternative approach is to utilize the non-mammalian models that have the inherent capacity to regenerate their...
Cephalosporium stripe (Cephalosporium gramineum) is an important disease limiting adoption of conservation tillage practices in the Pacific Northwest. The disease can cause severe loss of grain yield and quality in winter wheat (Triticum aestivum L.). Modified cultural practices can reduce disease incidence, but are not always dependable because of variation...
Hygro-mechanical effect is a general term applied to all phenomena that involves interaction between moisture content and mechanical characteristics of hygroscopic materials by analogy to thermo-mechanical effects. The hygromechanical effects include (but are not limited to) free shrinkage/swelling, effect of moisture on elastic modulus, strength, creep, failure mechanisms, and mechano...
High hydrostatic pressure processing (HPP) is a nonthermal process in which foods are subjected to pressures in the range of 100-700 MPa at room temperatures or higher. HPP is effective in reducing microbial counts and enzyme activity. The ability of HPP to modify the functional properties of proteins has become...
Epitaxial LaRh₁/₂Mn₁/₂O₃ thin films have been grown on (001)-oriented LaAlO₃ and SrTiO₃ substrates using pulsed laser deposition. The optimized thin film samples are semiconducting and ferromagnetic with a Curie temperature close to 100 K, a coercive field of 1200 Oe, and a saturation magnetization of 1.7μB per formula unit. The...
Four key aspects of the relationship between predatory hoverflies and the aphid pest Brevicoryne brassicae L. on broccoli were investigated in the Willamette Valley, Oregon USA: 1) the relationship between aphid density and hoverfly oviposition, 2) the larval voracity of key hoverfly species, 3) the preferences of hoverflies and broccoli...
In experimentally exposed mice, the environmental contaminant 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD) produces significant suppression of adaptive immune responses at low doses. However, the underlying biochemical and cellular mechanisms of TCDD-induced immunotoxicity have remained elusive since the identification of these effects nearly 30 years ago. Antigen-presenting cells (APC) constitute various populations of...
