Flash floods are considered to be one the worst kind of hazard. They are characterized by their suddenness, rarity, small scale, heavy rain and peak discharge, unpredictable, fast and violent movement. It has severe effects on human society in the form life losses, damages to property, roads, communication and on natural settings. Advances in hydrology, meteorology, engineering, using of GIS an...

It is shown that compressively strained Ge1-xSnx/Ge quantum wells (QWs) grown on a Ge substrate with 0.1 ≤ x ≤ 0.2 and width of 8 nm ≤ d ≤ 14 nm are a very promising gain medium for lasers integrated with an Si platform. Such QWs are type-I QWs with a direct bandgap and positive transverse electric mode of material gain, i.e. the modal gain. The electronic band structure near the center of Bril...

background : toxocariasis is a zoonotic disease caused by the ascarid of dogs and cats, the main representative of which is a toxocara canis . distribution of the disease is world wide and is more prevalent in children. the present study was carried out in children of kashmir valley, to determine the toxocariasis seropositivity. methods : for the present seroepidemiological study, blood samples...

The Remote Sensing Group at the University of Arizona has used ground-based test sites for the vicarious calibration of airborne and satellite-based sensors, of which the Railroad Valley Playa in north central Nevada has played a key role. This work presents a cross comparison of five satellite-based sensors that all imaged this playa on July 16, 2001. These sensors include the Advanced Land Im...

USDA Forest Service Gen. Tech. Rep. PSW-110. 1989. 3 Riparian zones occur at interfaces — ecological interfaces between different ecosystems and conceptual interfaces between different scientific disciplines. The plethora of definitions and delineations of riparian zones are inconsistent, confusing, and often contradictory, reflecting the diversity of disciplines, perspectives, and objectives f...

Families of very high-index planes, such as those which bifurcate spontaneously to form a hill-and-valley structure composed of opposing facets, provide natural templates for the directed growth of position-controlled self-organized nanostructures with shapes determined by the facet width ratio R. For example, deposition of a few ML of Ge on Si(173 100 373), corresponding to R(113/517) = 1.7, r...

DOI:10.17014/ijog.9.2.147-157 Outcrop of Nanggulan Formation, surrounded by Old Andesite Formation (OAF) in the eastern part Kulon Progo Dome, is very limited. Tectonic control interpreted as a contributing factor. activity can be shown morphometric aspect. The research purpose was to calculate valley floor - height ratio, stream gradient index, and drainage density Formations. method used fiel...
