  • A three-dimensional macroporous Cu/SnO2 composite anode sheet prepared via a novel method was prepared via a novel method that is based on selective reduction of metal oxides at appropriate temperatures. SnO2 particles were imbedded on the Cu particles within the three-dimensionally interconnected Cu substrate.

  • The formation of persistent organic pollutants such as polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), known collectively as dioxins, is a recognized concern for cement manufacturing. Dioxins have the potential to form if chlorine is present in the input fuel or raw materials. Formation can be repressed, however, by the high temperatures and long residence times that are standard in cement kilns (Karstensen 2008).

  • This approach has inherent limitations, including its depends on assumptions about the material and boundary conditions. the assumptions can be minimized through diagnostic load test (Schulz, 1993, Goble et al. 1990 and 1992). This approach combines stress response under load conditions is known with the model number of the bridge. The difference between the approach to the assessment of civil structures and other structures system discussed earlier is huge.

  • Tobacco smoking mostly in the form of cigarette smoking has been accused of impairing microcirculatory system and the relevant changes in vascular formations and functions may have a negative influence on the immune and inflammatory reactions in periodontal tissues. Smokers were reported to have significantly less number of vessels in inflamed gingival tissue compared to non-smokers (Rezavandi et al. 2002). Long-term smoking has an established negative effect on the vasculature of periodontal tissues.

  • In consultation with many local organisations and groups the Environment Agency has produced Catchment Flood Management Plans (CFMPs) covering the main 68 catchments in England. These documents set out the strategic context for managing flood risk in a catchment, helping decision makers by identifying the policy options being adopted to manage flood risks. They also help form the position we take in our work to manage assets, watercourses, flood forecasting, and to help land use planning and development.

  • For the comparison of the share of biomass within the microbial community samples were collected on monthly basis from the Adriatic Sea (N = 110) from one coastal (ST103) and one open sea (CA009) site during 2010. Seawater samples from the Adriatic Sea sites and offshore site in the English Channel were collected by Niskin bottles through vertical profile. At four shore sites from the English Channel samples were collected manually from the surface. All samples were fixed with formaldehyde (2% final concentration), kept in the dark at 4 ºC and analyzed within two weeks.

  • Due to their low aqueous solubilities, the PCBs and PAHs lay on the surface of soils and waters. PCBs and PAHs adsorb strongly to the organic fraction of soils (Girvin & Scott, 1997; Hiller et al., 2011). Soils contaminated with PCBs and PAHs are transported directly or indirectly by rivers to the water reservoir and are subsequently converted into the bed sediments. Therefore, soils could be considered as the primary sinks for these organic contaminants. PCBs and PAHs are persistent in the environment, resistant to degradation process, and accumulate in food chain.

  • Brewer, Minton, and Moser (2000), we evaluate an equation relating the determinants of C&I lending and the impact of derivatives on C&I lending activity. The major finding in this study is that the interest-rate derivatives allow commercial banks to lessen their systematic exposure to changes in interest rates, which enables banks to increase their lending activities without increasing the total risk level faced by the banks. This consequently increases the banks’ abilities to provide more intermediation services.

  • Ever since the Industrial Revolution, industrial activities have been accompanied by a problem: industrial waste. The commensurate increase in industrialization, urbanization and population growth are leading to production of enormous quantities of industrial wastes that may cause degradation in environment and health hazards. On the other hand, the desire for a healthy environment increases, which leads to the need for better ways of waste minimization, pollution prevention and better use of resources in achieving the required industrial and environmental standards....

  • The members of America’s Health Insurance Plans (AHIP) are committed to working with policymakers, health care providers, and consumers to contribute to our common fundamental interests in promoting a vibrant health care system and a vital economy. For the nation, and in the states, lack of health insurance is a major economic drain, one that costs $50 billion annually. We believe that access to health insurance coverage should be our number one domestic priority. In late 2006, we released a blueprint for achieving that goal.

  • In order for the digital cinema ecosystem to function properly, theaters and studios both needed assurance that any studio’s movie would be able to play in any theater on any authorized projection system. The major Hollywood movie studios also sought assurance that digital presentations would meet their requirements for security as well as color, brightness, clarity and resolution. To establish the required level of interoperability and define the required quality, the studios came together to create a unified standard.

  • Even if you don’t plan to sell your investment property right away, an appraiser will help you determine whether or not your investment is a good one financially. In fact, most lenders will require a full appraisal of any property to assure that they’re making a sound move by funding your purchase. You can check newspapers for current prices on similar properties. But you might also consider hiring an appraiser. By providing recent sales prices on similar homes, an appraiser can help you determine a current market value for the home you’ve got your eye on.

  • Sensors are still some time away from actual mass fabrication and use. Current smartsensor prototypes, such as the Berkeley Renee Mote, have a larger footprint and are generally restricted to the following sensor types: accelerometers, microphones, light, motion and magnetometers. We envision a design inclusive of these sensors types; however, our proposed application assumes a (not so) futuristic scenario that include sensors that test for nitrates (explosives), chemical toxins, biological toxins and radiation.

  • Already about two decades ago, Robert Lucas (1990) asked: “Why Doesn’t Capital Flow from Rich to Poor Countries?”, wondering why only very little capital in net term was flowing from the industrial world to developing economies. In the past years, this trend has even aggravated: Nowadays, in many cases, net capital flows have reversed and are now flowing from developing and emerging countries towards the rich world, especially towards the United States, United Kingdom, Australia and Spain.

  • The ancient carving industry in Jepara is famous locally and worldwide. Its reputation has attracted many related economic activities linked to wood production and processing, especially furniture making. Today, Jepara is a typical example of what is called an ‘industrial district’ 1 in which growth in one sector (furniture manufacturing) has attracted thousands of small to medium-sized industries to the Kabupaten (administrative district)2 . These in turn have created an opportunity for further subsidiary activities and industries.

  • Analysis of streambed sediments in the Salem, Oregon, area showed anomalously large concentrations of some elements and organic chemicals, indicating contamination from anthropogenic and/or geologic sources. The streambed sediment sample from Clark Creek, an urban basin, had large concentrations of polycyclic aromatic hyrdocarbons (PAHs), organochlorines, cadmium, lead, and zinc. The sample from the East Fork of Pringle Creek, which is a mostly urban basin, had the highest concentrations of DDD, DDE, and DDT compounds.
