Sintering is a method that makes powdered materials (such as fine ore or preparation concentrate) into block mass under conditions involving incomplete fusion by heating to high temperature. Its production is sinter which is irregular and porous (FU et al., 1996). The following parts are usually included in sintering process: acceptance and storage of iron-containing raw materials, fuel and flu...

Ethno-botany accounts for the study of relationship between people and plants for their use as medicines, food, shelter, clothing, fuel, fodder and other household purposes (Balick, 1996). It deals with the interaction of indigenous plants and the local inhabitants of the area. The aim of ethnobotanists is to explore how these plants are used as food, clothing, shelter, fodder, fuel, furniture ...

tion state of the world’s oceans are changing as a result of the addition of fossil fuel CO2 to the atmosphere (Kleypas et al. 1999; Feely et al. 2004; Orr et al. 2005). The pH of surface oceans has dropped by 0.1 units since the industrial revolution and if fossil fuel combustion continues at present rates, the pH of the world’s oceans will probably drop another 0.3 to 0.4 units by 2100 (Mehrb...

An analytic study was conducted on coupled partial differential equations. We formally derived new solitary wave solutions of generalized coupled system of Zakharov-Kuznetsov (ZK) and KdV equations by using modified extended tanh method. The traveling wave solutions for each generalized coupled system of ZK and KdV equations are shown in form of periodic, dark, and bright solitary wave solution...

The main objective of this paper is to study the performance of the various combinations of electrodes which plays an important role in the microbial fuel cells for the generation of electricity. The present work is an experimented investigation concerned with selection of the electrodes for the best performance of a microbial fuel cell. The various combinations of anode/cathode materials like ...

Methyl-decanoate (MD) is an important surrogate fuel component representing the methyl-ester fraction in biodiesel. In recent years different experimental studies using MD as fuel were reported; detailed as well as reduced mechanisms were developed for both improving our kinetic understanding and engineering applications. Jet stirred reactor (JSR) experiments were performed by Dagaut et al. (20...

Pt-Al and Pt-Y-Al thin-film electrodes on yttria-stabilized zirconia electrolytes were prepared by dealloying of cosputtered Pt-Al or Pt-Y-Al films. The selective dissolution of Al from the Pt-alloy compound causes the formation of a highly porous nanowire network with a mean branch thickness below 25 nm and a pore intercept length below 35 nm. The oxygen-reduction capability of the resulting e...

A recent Health Effects Institute (HEI) study (Bagley, et al., 1996) showed dramatic increases in nanoparticle emissions for a 1991 engine compared to 1988 engine, both running on very low sulfur fuel. This has raised great concerns about very high nanoparticle emissions from modern, low particle mass emission engines. However it is important to recognize that the 1988 engine also produced high...

Across the eastern US, there is on average an estimated 36 Mg ha of dead woody fuel (Chojnacky et al. 2004). Variation in fuel type, size, and flammability across the region makes selection of treatment options critical for effective fuels management. The eastern U.S. is a complex landscape characterized by highly fragmented forests, large areas of wildland urban interface, and vast differences...
