  • Rice is one of the most important crop plants over the world. Our work studied on the physiological responses of rice seedlings (Oryza sativa cv. Dongjin) under drought condition by withholding water. In response to drought treatment, three-week-old rice seedlings exhibited typically morphological responses as leafs rolling and drying at 48 h after exposure to water deficit.

  • The ubiquitination and subsequent degradation of stress-induced abnormal proteins are indispensable to cell survival. We previously showed that a yeast (Saccharomyces cerevisiae) mutant carrying a single amino acid change, Ala401Glu, in RSP5, which encodes an essential E3 ubiquitin ligase, is hypersensitive to various stresses.

  • The rock mass around an underground opening is subjected to a unique stress path that results in low radial confinement and both tangential loading and unloading conditions near the wall. As a result, the rock mass strength near underground excavations is controlled by failure mechanisms dominating at low confinement. Hence, when constructing underground works in hard rock, two general scenarios are encountered: (1) structurally controlled gravity-driven failures; and (2) stress-induced failure with spalling and slabbing....

  • This group constitutes the majority of dietary antioxidants (and also of secondary plant metabolites). Plants typically produce polyphenols as a defence against herbivores and various stresses in general. It is estimated that in Westernized countries, polyphenol intake is approx. 0.4-1g/d and capita (reviewed by Bouayed and Bohn, 2010), with higher intake for persons following a vegetarian diet. Food sources that are especially rich in polyphenols include, among others, potato, plums, leafy vegetables, whole grain products, and coffee (Souci et al., 2000). ...

  • Investor base: participation by different investors in the government bond market has grown more diversified. Of the various actors in this market, banks tend to invest in relatively shorter term bonds to match their short-term liability. Pension funds and insurance companies prefer hedging long-term inflation risks by investing more in inflation linked bonds. Non-residents concentrate their direct exposure to fixed rate instruments, but with maturity less than 3 years.

  • Plants are sessile organisms and as such must have mechanisms to deal with both abiotic and biotic stresses to ensure survival. The term “abiotic stress” includes many stresses caused by environmental conditions such as drought, salinity, UV and extreme temperatures. Due to global climate change it is predicted that abiotic stresses will increase in the near future and have substantial impacts on crop yields (Intergovernmental Panel of Climate Change; http://www.ipcc.ch).

  • Fossil fuel combustion for transportation contributes to air pollution, and air pollution degrades human health. However, the path from transportation to human health costs is anything but straightforward. Which pollutants are produced in which proportions depend on a number of factors, including the vehicle and fuel used and the driving conditions of a particular trip. These emissions are dispersed into the ambient air according to atmospheric conditions, which also influence the extent to which they react to form secondary pollutants.

  • A distinction is to be made between the terms 'efficacy' and 'effectiveness'. Efficacy is defined as "the probability of benefit to individuals in a defined population from a medical technology applied for a given medical problem under ideal conditions of use". By contrast, effectiveness is considered to have all the attributes of efficacy but to reflect "performance under ordinary conditions by the average practitioner for the typical patient" [12].

  • Dynamicity of participants: Some P2P systems, such as [10], assume a fixed set of nodes in the system. However, one of the greatest potential strengths of P2P systems is when they eschew reliance on dedicated infrastructure and allow peers to leave the system at will. Even under these conditions, participants typically have broadly varying availability characteristics. Some peers are akin to servers: their membership in the system stays largely static. Others have much more dynamic membership, joining and leaving the system at will.

  • IN BOTH NATURAL AND AGRICULTURAL CONDITIONS, plants are frequently exposed to environmental stresses. Some environmental factors, such as air temperature, can become stressful in just a few minutes; others, such as soil water content, may take days to weeks, and factors such as soil mineral deficiencies can take months to become stressful. It has been estimated that because of stress resulting from climatic and soil conditions (abiotic factors) that are suboptimal, the yield of field-grown crops in the United States is only 22% of the genetic potential yield (Boyer 1982).
