Current study was carried out with aim to evaluate the effect of pressurized irrigation methods and furrow irrigation method with municipal effluent on distribution of salinity and moisture in the soil profile. The experimental study was designed by split plot layout with three irrigation methods including furrow, surface drip (SD) irrigation and subsurface drip irrigation (SSD) and two water q...

technique of remote sensing and its satellite products has many implementations in agricultural science and national resources. in this study, wheat yield in esfahan province, iran, were derived from modis satellite data over periods of 2000-2001(dry year) and 2004-2005 (wet year). for this purposes, 68 modis products of surface reflectance (mod09ga) and land surface temperature lst (mod11a2) o...

It has been known that workers of a honey bee colony bring water droplets into their hive, spraying it on the frames and brood cells, and fanning their wings when ambient temperature rises higher than appropriate. Meanwhile several species from Namibian beetles demonstrate unique water harvesting strategies from the morning fog via the bumps and troughs above their elytra, where water droplets ...

Semiconductor photocatalysis has been identified as a promising avenue for the conversion of solar energy into environmentally friendly fuels, most notably by the production of hydrogen from water.[1–5] Nanometer-scale materials in particular have attracted considerable scientific attention as the building blocks for light-harvesting applications.[6,7] Their desirable attributes include tunabil...

Environmental dusts settle on surfaces and influence the performance of concentrated solar energy harvesting devices, such as aluminum troughs. The characteristics of environmental dust and the effects of mud formed from the dust particles as a result of water condensing in humid air conditions on an aluminum wafer surface are examined. The dissolution of alkaline and alkaline earth compounds i...

Selective harvesting can cause evolutionary responses in populations via shifts in phenotypic characteristics, especially those affecting life history. Brine shrimp (Artemia franciscana) cysts in Great Salt Lake (GSL), Utah, USA are commercially harvested with techniques that select against floating cysts. This selective pressure could cause evolutionary changes over time. Our objectives are to...

The water splitting properties of InGaN photoanodes equipped with ZnO nanowires were examined in this study. Over the solar spectrum range, the absorbance exhibited a remarkable increase due to the enhanced light absorption caused by the ZnO nanowires. By varying the ZnO nanowires length, the photo-to-current density of photoanodes was increased from 0.017 to 0.205 mA/cm2 at 1.23 V versus rever...

this research was conducted in order to study the effect of climate and geology factors on groundwater sources in mahvelat plain. in order to study the groundwater quality and quantity considering groundwater resources including wells and qanats; using groundwater surface, electric conduction (ec) and the total density solution (tds), the maps of groundwater surface fluctuation and quality para...

in today’s world renewable energy is highly demanding because of increasing oil and fuelprices, desire and necessity to avert irreversible climate damage and also the unreliability of the non -renewablesources. in renewable energy, water is an important source. previously water is used only for survivalof human being as much as food but no attentionhas been givenen to economical use and conserv...
