The growth of population in a worldwide scale and the social vulnerability of different human communities subjected to war, economy collapse, ethnical persecution and poverty impose a strong pressure to occupy multi-hazard environments, like flood plains and hill slopes subject to landslides (Sullivan-Wiley and Gianotti 2017). As human communities occupy unstable hill slope areas, activities li...

in this paper, we propose and evaluate a novel design of a lightly doped drain and source carbon nanotube field effect transistor (ldds-cntfet) with a negative differential resistance (ndr) characteristic, called negative differential resistance ldds-cntfet (ndr-ldds-cntfet). the device was simulated by using a non equilibrium green’s function method. to achieve this phenomenon, we have created...

Complex traits often involve interactions between different genetic loci. This can lead to sign epistasis, whereby mutations that are individually deleterious or neutral combine to confer a fitness benefit. In order to acquire the beneficial genotype, an asexual population must cross a fitness valley or plateau by first acquiring the deleterious or neutral intermediates. Here, we present a comp...

Iron chrome oxide (FeCr 2O4), is a commercially viable and major ingredient of stainless steel. The Odisha state in India possesses 98% the pre-Cambrian India’s Chromite ore deposits Sukinda valley, Jajpur District. To meet present escalating demand for chromium steel industries, it urged to extract more satiate domestic needs. depletion deposits, rise demand, fewer mines, less conversion from ...

The topographical morphology of the loess landform on Loess Plateau exhibits remarkable textural features at different spatial scales. However, existing topographic texture analysis studies are usually dominated by statistical characteristics and missing structural characteristics. At same time, there is a lack regularity calculation methods for DEM digital terrain analysis. Taking as study are...

We have examined the optical properties of self-assembled InAs quantum dots ~QDs! grown on prepatterned GaAs~001! substrates with polarization sensitive and time-resolved cathodoluminescence ~CL! imaging and spectroscopy techniques. The InAs QDs were formed using a novel application in self-assembled molecular beam epitaxial growth, which entailed the growth of InAs on preformed @11̄0#-oriented ...

Hydrologic response varies within a watershed as a function of topography, soil, and land cover. Spatial and temporal data from experimental watersheds may provide information on where, when, how, and why the response varies. This study examined the hydrologic response of an agricultural watershed, FD-36, in the Appalachian Valley and Ridge physiographic region. FD-36 is characterized by shallo...
