Abstract Mini scale carbon-soil-sand filtering system can be highly effective on surface waters, without requiring the use of coagulation preceding filtration. It is effective in removing suspended solids, toxic metals and imposes a 98-99 % reduction in bacteria. A novel filtering system is described here, where the bacterial removal zone was set a

A Hierarchical 3D-Torus (H3DT) network is a 3D-torus network of multiple basic modules, in which the basic modules are 3D-mesh networks, has been proposed for efficient 3D massively parallel computers. The static network performance, the number of vertical links for 3D implementation, and the VLSI layout area of the H3DT network was investigated. I

This paper explores the develop optimized model to investigate the effects of peak current,pulse on time and pulse off time in electric discharge machining (EDM) performance on titanium alloy utilizing copper tungsten as electrode and positive polarity of the electrode. The experiments are carried out on Ti6Al4V. Experiments were conducted by varyi

Mercury concentrations and speciation were determined in surface water samples taken from rivers in the vicinity of industrial area, in Johore Malaysia. Samples were collected from the same sites before and immediately after rainfall. The aim of this study is to assess the influence of seasonal change in river water on the concentration of mercury

A simple and less expensive solvent extraction method was used with inductively coupled plasma mass spectrometry (ICP-MS) in the speciation of two environmentally significant,toxic forms of arsenic: arsenite and arsenate. Dissolved inorganic arsenic species in drinking waters from reservoirs and treatment plants were determined by the inductively c

Advancement and innovation in developing water filtering system enhances immensely in the field of water purification. In this study the acid treated rice husk ash was used as SiO2 source in the preparation of zeolite Y, a medium siliceous zeolite used as an ion exchangers in water treatment process. Purity, pore size distribution, FT-IR and SEM mi

Abstract. Thermal and acid wash treatment of rice husk has been conducted 550 to 600 0C in air atmosphere and chemical treatments consisted of acid, H2SO4. Purity, pore size distribution, FT-IR and SEM micrographs of treated and non-treated samples are presented. In this study the acid treated rice husk ash was used as SiO2 source in the preparatio

A Modified Hierarchical 3D-Torus (MH3DT) network is a 3D-torus network consists of multiple basic modules, in which each basic module itself is a 3D-torus network. Dynamic communication performance has been evaluated using dimension-order routing and $2$ virtual channels (VCs) under uniform traffic patterns but not under non-uniform traffic pattern

Breast feeding by the mother to her new born infant is greatly beneficial. It is prescribed as Almighty commanded the mother to breast feed her child for two years: "The mothers shall give such to their offspring for two whole years” if the father desires to complete the term. But he shall bear the cost of their food and clothing on equal len

In the near future many aspect of our life will be encompassed by tasks performing in cooperation with robot. The application of robot in home automation, agriculture production and medical operations etc will indispensable. As a result robot needs to be made human-friendly and to execute tasks in cooperation with human. Researchers proposed many n
