the exponential growth of urbanization leads to increase in severity of environmental problemsespecially assonated with disposal of solid waste. with considering the increasing rate of solid waste generation in urban area, the problem of availability of space required to dispose it off is become a concern for planners and administrators of urban local bodies (ulb). in order to cope up with the ...
The electrogeochemical method is a new exploration technique with a foundation of electrochemistry. The method has ability to detect hidden ore deposits which have been covered with overburden placers and topsoil. Although this technique is unique and powerful, no attempt was made in our country to apply this new method practically so far. In this method an artificial DC electrical current has ...
Disposal packages containing high heat generating spent nuclear fuels (SNF) require improved heat transfer to keep the peak cladding temperature from going above the tolerance limit. Filling the accessible void spaces between the container and the SNF with a high heat conducting metal is a potential solution. In metal casting, it is well known that a gap forms at the metal-mold interface due to...
Single crystals of {FeHo(6)}I(12)Ho were obtained during the reaction of HoI(3) with metallic holmium and iron in a sealed tantalum container. The crystal structure consists of isolated holmium clusters encapsulating a single Fe atom, {FeHo(6)} ( symmetry). The rare earth metal atoms are surrounded by 12 edge-capping and six terminal iodide ligands that either connect the clusters to each other...
Abstract A new low-energy and eco-friendly method for extracting lead from waste PbO-containing funnel glass is required. Conventional methods use either energy intensive smelting reduction at temperatures higher than 1273 K or involve phase separation of the glass, requiring an acid treatment to extract elemental Pb partitioned in one decomposed phases as 2+ ion. In this study, mechanism a uni...
In the first part of this paper we study minimal representations of simply connected simple split groups G of type Dk or Ek over local nonarchimedian fields. Our main result is an explicit formula for the spherical vectors in these representations. In the case of groups over R and C, such a formula was obtained recently in [8]. We also use our techniques to study the structure of the space of s...
This paper analyzes the influence of the supply chain management on the environmental impact of a 2400 L waste disposal container used in most cities of Spain. The studied functional unit, a waste disposal container, made up mostly of plastic materials and a metallic structure, and manufactured in Madrid (Spain), is distributed to several cities at an average distance of 392 km. A life cycle as...
Mineralogical Association of Canada Short Course 43, Winnipeg MB, May 2013, p. xx-xx INTRODUCTION The direct disposal of spent nuclear fuel in geologic repositories, built several hundred metres underground, has been under consideration internationally for 20 to 30 years. Various geologic formations are being, or have been, studied including tuff rock, salt domes, sedimentary clay deposits an...
