Abstract:
Au cours des dernières années, la demande de plus en plus forte pour des mémoires non-volatiles performantes, a mené au développement des technologies NOR Flash et NAND Flash, qui dominent aujourd'hui le marché des mémoires non-volatiles. Cependant, la miniaturisation de ces technologies, qui permettait d'en réduire le coût, laisse aujourd'hui entrevoir ses limites. En conséquence, des mémoires alternatives et émergentes sont développées, et parmi celles-ci, la technologie des mémoires à changement de phase, ou PCRAM, est l'une des candidates les plus prometteuses tant pour remplacer les mémoi

The analog equalizer consists of two gain stages and two filter stages, totally providing at most 14.9-dB boosting and 4.8-dB dc gain. It compensates sufficiently for the loss of the 5-cm channel on a Rogers board, and has a 35-mV input sensitivity. The following is a 40-Gb/s full-rate CDR, constructed with a lin

Abstract:
The University of Georgia Department of Geography’s Center for Geospatial Research (CGR), with the support of the National Park Service (NPS) Vegetation Mapping Inventory (VMI) Program, described and mapped vegetation at Fort Matanzas National Monument (FOMA). This mapping effort was accomplished through collaboration with the NPS Southeast Coast Network (SECN), the North Carolina office of NatureServe (Durham, N.C.), and Amec-Foster-Wheeler Environmental &amp; Infrastructure, Inc. A final vegetation map for Fort Matanzas NM was created to represent the vegetation occurring within the park dur

Abstract:
Bacterial cellulose (BC) was investigated as a novel material for preparing activated carbons. BC was dried by heating and it was carbonized with a chemical activation process using phosphoric acid (H₃PO₄) as an activating agent at different temperatures (400, 500 and 600 °C). The properties of the activated carbons were characterized such as chemical property, structure, pore size, thermal property by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), N₂ -physisorption (BET), scanning electron microscopy (SEM) , thermal gravimetric (TGA). The obtained BC activated carbo

Abstract:
Hanging gardens are the most common type of spring at Arches National Park (NP) and Natural Bridges National Monument (NM). They are also present at Canyonlands National Park, but hanging gardens are rare off the Colorado Plateau. Their cliffside setting provides stable access to water without flood disturbance. This combination provides unique habitat that is rich in endemic plant species. The diffuse, seeping emergence of water makes measuring springflow impossible at most sites. Park managers have an interest in monitoring hanging gardens—especially as the climate warms and aridity and wate

Abstract:
Part I: The purpose of the investigation was to develop the extraction process that was simple, practical and giving high yield. The maceration of dried powder of Garcinia mangostana fruit husk with ethyl acetate gave yellow crystalline powder of mangostin. The yield was calculated as 7.47%. The identification of the Garcinia mangostanahusk extract was carried out by thin-layer chromatography (TLC) and differential scanning calorimetry. The TLC of mangostin was done by using the alumina sheet and ethyl acetate: hexane (3:1) as mobile phase. The Rf value as compared with standard mangostin was
