World-wide water scarcity, especially in the developing world, indicates a pressing need to develop inexpensive, decentralized small-scale desalination technologies which use renewable resources of energy. This paper provides a comprehensive review of the stateof-the-art in one of the most promising of these technologies, solar-driven humidification-dehumidification (HDH) desalination. Previous...

AMERICAN METEOROLOGICAL SOCIETY | 1743 T he transport and transformations of water substance in the global water cycle are of fundamental and primary importance for understanding the ecosystems, the land surface hydrology that supports them, and the management of water resources for humans. Th e water cycle is also critical for predicting weather, and the long-term climate balance of the planet...

Many bacterial pathogens are well characterized but, in some cases, little is known about the populations from which they emerged. This limits understanding of the molecular mechanisms underlying disease. The crop pathogen Pseudomonas syringae sensu lato has been widely isolated from the environment, including wild plants and components of the water cycle, and causes disease in several economic...

Aquatic immersion has been reported to produce a significant number of physiological changes in blood pressure, heart rate variability (HRV), autonomic nervous system (ANS), and core temperature in young healthy subjects. The purpose of this study was to examine the impact of water immersion in younger and older populations, determining whether there are age related differences for ANS regulati...

this paper gives an account of the implementation of geomorphological, hydrogeological, hydrochemical and isotopic techniques to understand groundwater-surface water interactions in a multiple use area, los padres-la brava corridor (se of buenos aires province, argentina). the isophreatic map reveals a regional flow from the sw to ne sector, and allowed us to define the effluent-influent behavi...

Due to the semi aquatic habits and the overlap of the geographical distribution of the water-rat, Nectomys spp., with schistosomiasis endemic areas, these wild rodents are very likely to acquire Schistosoma mansoni infection in their daily activities. The role of the water-rat in the S. mansoni cycle would be substantiated if one could prove that these rodents acquire the parasite during their ...

[1] Water vapor in the subtropical troposphere plays an important role in the radiative balance, the distribution of precipitation, and the chemistry of the Earth’s atmosphere. Measurements of the water vapor mixing ratio paired with stable isotope ratios provide unique information on transport processes and moisture sources that is not available with mixing ratio data alone. Measurements of th...

To further understanding of the environmental implications of rainwater harvesting and its water savings potential relative to conventional U.S. water delivery infrastructure, we present a method to perform life cycle assessment of domestic rainwater harvesting (DRWH) and agricultural rainwater harvesting (ARWH) systems. We also summarize the design aspects of DRWH and ARWH systems adapted to t...

Neurogenesis involves cell proliferation, cell cycle arrest, differentiation, migration and the natural developmental death of the neural precursors. These processes are highly co-ordinated and governed by cell-cycle genes and neural transcription factors. Zn plays a crucial role as a functional and structural component of enzymes and transcription factors and components of the intracellular si...

In the present research, energy in geothermal fluid is utilized to generate power. first case of power generation, model double-effect instantaneous evaporation cycle employed, and second one, single-effect combined Rankine with different organic fluids are utilized. The effect several examined. SPECO method has also been applied economic analysis. Given analysis, net generation highest for wat...
