Given the high numbers of deaths and the debilitating nature of diseases caused by the use of unclean water it is imperative that we have an understanding of the factors that control the dispersion of water borne pathogens and their respective indicators. This is all the more important in developing countries where significant proportions of the population often have little or no access to clea...

BACKGROUND Earthquakes, floods, droughts, storms, mudslides, landslides, and forest wild fires are serious threats to human lives and properties. The present study aimed to study the environmental characteristics and pathogenic traits, recapitulate experiences, and augment applications of medical reliefs in tropical regions. METHODS Analysis was made on work and projects of emergency medical ...

We present evidence from a variety of physical and biological proxies for a severe drought that affected the mid-continent of North America between 4.1 and 4.3 ka. Rapid climate changes associated with the event had large and widespread ecological effects, including dune reactivation, forest fires and long-term changes in forest composition, highlighting a clear ecological vulnerability to simi...

ABSTRACT Phytophthora capsici is a diverse species causing disease on a broad range of both temperate and tropical plants. In this study, we used cultural characteristics, amplified fragment length polymorphism (AFLP), and DNA sequence analyses of the ribosomal internal transcribed spacer (ITS) region and mitochondrial cytochrome oxidase II (cox II) genes to characterize temperate and tropical ...

the present study aims to have a comparative study of the results, from biological monitoring as well as conventional method, based on physico-chemical variables. water quality index (wqi) and planktonic diatom metrics have been used to determine water quality and ecological conditions of the dong nai river (dnr) and canonical correspondence analysis (cca) to find out the main environmental var...

scorpionism is a known significant problem of medical and social importance in many tropical and subtropical regions including the middle east. in iran, highest prevalence of scorpion sting about 60% of all the stings has been reported from khuzestan province. among the 21,000 cases of reported scorpion stung patients, 12% were caused by h. lepturus, but contributed to 95% of all moralities in ...

The worldwide production of maize (Zea mays L.) is frequently impacted by water scarcity and as a result, increased drought tolerance is a priority target in maize breeding programs. While DREB transcription factors have been demonstrated to play a central role in desiccation tolerance, whether or not natural sequence variations in these genes are associated with the phenotypic variability of t...

5 [1] The assumption that tropical cyclones respond primarily to sea surface temperatures (SSTs) local to 6 their main development regions underlies much of the concern regarding the possible impacts of 7 anthropogenic greenhouse warming on tropical cyclone statistics. Here the observed relationship between 8 changes in sea surface temperature and tropical cyclone intensities in the Atlantic ba...
