Cytoplasmic methionyl tRNA synthetase (MetRS) is one of more than 20 cytoplasmic aminoacyl tRNA synthetase enzymes (ARS). This family of enzymes catalyzes a process fundamental for protein translation. Using a combination of genetic mapping, oligonucleotide array comparative genomic hybridization, and phenotypic correlation, we show that mutations in the essential gene, let-65, reside within th...

We live in a world where everyday artifacts are designed and augmented as media interfaces. Technologies are created based on this mission, which enable everyday objects to sense, interact, and communicate with us. Since the design and deployment of any interactive sensing system requires pre-defined content and sensor mapping between the hardware and software systems, having a platform that is...

base and precious metals associated with porphyry, epithermal and acid sulphate or high-snlphidation hydrothermal systems (Panteleyev, 1992; Panteleyev and Koyanagi, 1993, 1994). The majority of these systems are associated with the Early to Middle Jurassic Island Plutonic Suite and Early Jurassic B O M ~ Group rocks. The regional mapping component of this study focused primarily on potential t...

Archaeology and indigenous history of Native Amazonian peoples in the Upper Xingu region of Brazil reveal unexpectedly complex regional settlement patterns and large-scale transformations of local landscapes over the past millennium. Mapping and excavation of archaeological structures document pronounced human-induced alteration of the forest cover, particularly in relation to large, dense late...

Global mineralogical mapping of Mars by the Observatoire pour la Mineralogie, l'Eau, les Glaces et l'Activité (OMEGA) instrument on the European Space Agency's Mars Express spacecraft provides new information on Mars' geological and climatic history. Phyllosilicates formed by aqueous alteration very early in the planet's history (the "phyllocian" era) are found in the oldest terrains; sulfates ...

A field-mapping and crystal-chemical study of two aluniteand halloysite-rich deposits in the Turplu area, situated northwest of Balıkesir on the Biga Peninsula of northwest Turkey reveals a mineralogically diverse and a potentially economic clay deposit. The mineral assemblage along fault zones is dominated by halloysite and sometimes alunite. The alunite is nearly end-member in composition (a ...

The Japanese ASTER sensor on board the US Terra satellite was launched in December 1999 to establish a spaceborne capability for high spatial, multispectral visible-shortwave infrared and thermal infrared remote sensing data mapping of the Earth’s environment. The Mt Fitton test site in South Australia was chosen to test the ability of the ASTER instrument for geological mapping having been pre...

This study produces alteration mineral maps based on WorldView-3 (WV-3) data and field shortwave-infrared (SWIR) spectroscopy. It is supported by conventional analytical methods such as X-ray diffraction, fluorescence, electron probe micro analyzer an initial step for exploration in eastern Tsogttsetsii, Mongolia, where access limited. Distributions of advanced argillic minerals (alunite, dicki...

wettability alteration is an important method for increasing oil recovery from oil-wet carbonatereservoirs. chemical agents like surfactants are known as wettability modifiers in carbonate systems.oil can be recovered from initially oil-wet carbonate reservoirs by wettability alteration from oil-wetto water-wet condition with adding dilute surfactant and electrolyte solutions. this paper invest...

One of the most important characteristics of annular arrays is their superior focal capabilities. In order to achieve the desired focussing, each of the elements is fired in different times. The delay times used for beam focussing are called focal laws. The focal laws are automatically calculated from the inspection software. In order to make sure that the focal laws are calculated correctly fr...
