Keywords: SWAT Continuous rainfall–runoff model Eastern Desert Sinai peninsula Remote sensing GIS s u m m a r y Efforts to understand and to quantify precipitation and its partitioning into runoff evapo-transpiration, and recharge are often hampered by the absence or paucity of appropriate monitoring systems. We applied methodologies for rainfall–runoff and(More)
The dramatic increase in space-borne sensors over the past two decades is presenting unique opportunities for new and enhanced applications in various scientific disciplines. Using these data sets, hydrogeologists can now address and understand the partitioning of water systems on regional and global scales, yet such applications present mounting challenges(More)
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(More)
To address a nation's or a region's water-related sustainability problems, one of key elements is to characterize and quantify renewable water resources for a better management. In the arid and semiarid areas, it has been a great challenge to quantify the renewable water resources due to limited access and monitoring systems on the land. This study(More)
CONTEXT Lower urinary tract symptoms (LUTSs) in elderly males are usually related to benign prostatic hyperplasia (BPH) in the majority of cases. It is estimated that BPH affects half of men above the age of 50 years. Recently, a relationship between Vitamin D deficiency and LUTS in elderly males has been reported. AIMS The aim of this study was to(More)
—This paper reports a 30 mm × 30 mm × 34 mm mini-scale parallel manipulator using shape-memory-alloy (SMA) microactuators that poses various advantages such as a large actuation force and a high robustness with a simple mechanical structure. The developed parallel manipulator that uses four SMA actuators and four bias springs is able to perform linear(More)
A Stewart platform is a parallel manipulator robot that is able to perform three linear movements, lateral, longitudinal, and vertical, and three rotations, pitch, yaw, and roll. This paper reports a 30 mm × 30 mm × 34 mm miniscale Stewart platform using TiNiCu shape-memory-alloy (SMA) actuators. The proposed Stewart platform possesses various advantages,(More)
Satellite observations were used to test the validity of previously identified favourable conditions for the formation of freshwater lenses, identify additional potential occurrences, and model modern potential recharge in the Raudhatain Watershed (3696) in northern Kuwait. Favourable conditions include infrequent yet intensive precipitation events,(More)
