soil and water salinity are amongst the severe and progressive problems worldwide which affects most cropland areas of iran. using endophytic microorganisms (which are amongst the most important soil microorganisms) to alleviate the detrimental effect of environmental stresses such as salinity is recently globally considered. in order to test the effects of azospirillum strains and fungus pirif...

this paper presents a mapping procedure for risk mapping of water and wind erosion, whichhelps to identify protective measures needed in the planning and management of natural parks. the map of water erosion risk was developed by combining the original and revised universal soil loss equation methodologies (usle-rusle), and the map of wind erosion risk was developed using quirantes’ method. usi...

Recent progress is reviewed in the understanding of convective interaction with water vapor, and changes associated with water vapor in warmer climates. Progress includes new observing techniques (including isotopic methods) that are helping to illuminate moistureconvection interaction, better-observed humidity trends, new modeling approaches, and clearer expectations as to the hydrological con...

GOAL, SCOPE AND BACKGROUND Aquaculture activities are well known to be the major contributor to the increasing level of organic waste and toxic compound in the aquaculture industry. Along with the development of intensive aquaculture in China, concerns are evoked about the possible effects of ever-increasing aquaculture waste both on productivity inside the aquaculture system and on the ambient...

Phenolic compounds are an important group of contaminants in tap water (Kraybi l l 1978). To prevent water-transmittable epidemic diseases, drinking water is often chemically chlorinated, which may cause chemical chlor inat ion of these contaminants and the formation of stable and unstable chloro-derivat ives. Although industr ia l and agr icu l tura l practice appear to be major contributors o...

Texas waters provide one of the most important developmental and foraging habitats for juvenile green turtles (Chelonia mydas) in the western Gulf of Mexico, but hypothermic stunning is a significant threat and was the largest cause of green turtle strandings in Texas from 1980 through 2015; of the 8,107 green turtles found stranded, 4,529 (55.9%) were victims of hypothermic stunning. Additiona...
