Water is the most important substance on Earth. While not a mineral itself, water rules the mineral kingdom since interaction with water is fundamental to all geological processes. And water can even slip into the mineral kingdom by freezing into ice. Water occurs in the hydrologic cycle as soil water, groundwater and surface water. We also find water vapor in the atmosphere and frozen water in...

a r t i c l e i n f o 14 C adjusted model age Paleowesterlies Paleomonsoon Sixteen groundwater samples collected from production wells tapping Lower Cretaceous Nubian Sandstone and fractured basement aquifers in Sinai were analyzed for their stable isotopic compositions, dissolved noble gas concentrations (recharge temperatures), tritium activities, and 14 C abundances. Results define two group...

This paper considers the target patrolling problem which asks a set of mobile data collectors (or data mules) to efficiently patrol a set of given targets. Since the time interval (also referred to visiting interval) for consecutive visits to each target reflects the monitoring quality of this target, the goal of this research is to balance the visiting interval of each target. This paper first...

One-km resolution MODIS-based mean annual evapotranspiration (ET) estimates in combination with PRISM precipitation rates were correlated with depth to groundwater (d) values in the wide alluvial valley of the Platte River in Nebraska for obtaining a net recharge (Rn) vs. d relationship. MODIS cells with irrigation were excluded, yielding a mixture of predominantly range, pasture, grass, and ri...

Aquifer recharge presents advantages for integrated water management in the anthropic cycle, namely, advanced treatment of reclaimed water and additional dilution of pollutants due to mixing with natural groundwater. Nevertheless, this practice represents a health and environmental hazard because of the presence of pathogenic microorganisms and chemical contaminants. To assess the quality of wa...

I have been personally looking forward to many of us coming together again at EN21X for exceptional education, working in general assembly further our association, reuniting with friends, making new having fun, and recharging. Reunited, it feels so good! That is a line from the 1978 hit song by Peaches Herb, that phrase what humming as we prepare gather in-person virtually EN21X. will be reunio...

To develop electrical busses for applications with a fast recharge system in stations, PVI has been testing some electrical energy components like supercapacitors and batteries with high power density. Neverthless, supercapacitors limit average autonomy between two recharge points, due to their poor energy density. On the other side cycle life of batteries are very dependent on current. To surm...

The Kumamoto area, Kyushu, Japan has 1,041km in area and about 1milion in population. This area is a greatest area in Japan which depends on groundwater for all of drinking water. Quantity of this local groundwater use is about 200MCM during the year. It is understood that the main recharging area of groundwater exist in the rice field zone which have high infiltrate height ahead of 100mm/ day ...

Systems with energy harvesting capability from stochastic sources have been widely studied in the literature. However, the determination of the recharge time of such systems has not received as much attention as it deserves. Here, we examine the recharge time of a battery/super-capacitor when the energy arrival is discrete stochastic. We consider the cases when the energy storage system is mode...
