The ability of sulfate-reducing bacteria (SRB) to reduce chromate VI has been studied for possible application to the decontamination of polluted environments. Metal reduction can be achieved both chemically, by H2S produced by the bacteria, and enzymatically, by polyhemic cytochromes c 3. We demonstrate that, in addition to low potential polyheme c-type(More)
Large gravitational wave interferometric detectors, like Virgo and LIGO, demonstrated the capability to reach their design sensitivity, but to transform these machines into an effective observational instrument for gravitational wave astronomy a large improvement in sensitivity is required. Advanced detectors in the near future and third-generation(More)
This study compared the performance of surface electromyographic (sEMG) sensors for different detection conditions affecting the electro-mechanical stability between the sensor and its contact with the skin. These comparisons were made to gain a better understanding of how specific characteristics of sensor design and use may alter the ability of sEMG(More)
Advanced gravitational wave interferometers, currently under realization, will soon permit the detection of gravitational waves from astronomical sources. To open the era of precision gravitational wave astronomy, a further substantial improvement in sensitivity is required. The future space-based Laser Interferometer Space Antenna and the third-generation(More)
A likelihood approach for ÿtting asymmetric stochastic volatility models is proposed. It is ÿrst shown that, using a quadrature method, the likelihood of these models may be approximated, with the required level of accuracy, by a function that may be easily evaluated using matrix calculus along with its ÿrst and second derivatives. The approximated(More)
A multidisciplinary approach was used for delineating the mechanisms controlling water sorption into modified block co-poly-(ether/amide) (PEBAX) membranes. In particular, incorporation of aromatic sulfonamide (KET) into the polymer matrix led to a nonlinear increase of water sorption in the membrane. The modification in sorption was accompanied by a(More)
The correct estimation of building energy consumptions is assuming an always increasing importance, and a detailed reproduction of building structures, with all the single components involved, is necessary to achieve this aim. In addition, the current ecological development tries to limit the use of natural raw materials as building components, in favor of(More)
The reaction of [WOF4(MeCN)] with the diphosphines, Me2PCH2CH2PMe2 or o-C6H4(PMe2)2, in anhydrous Et2O produced high yields of [WOF4(diphosphine)], the X-ray crystal structures of which reveal seven-coordinate pentagonal bipyramidal molecules with axial O/F. In contrast, the reaction of [WOF4(MeCN)] and PMe3 forms the six-coordinate [WOF4(PMe3)]. These(More)
