Abstract: Soil serves as one of the basic medium of life as a variety of elements‚ which are vital to life are embedded in it. However‚ the human activities are polluting the soil unintentionally. Consequently‚ a wide range of contaminants enter the soil. Nevertheless‚ heavy metals are the most toxic of all the pollutants. Among these‚ lead‚ cadmium‚ chromium‚ mercury and arsenic are most toxic and can cause multiple organ damages even when present in small amount. Although‚ these elements are necessary

This lead to questions and challenges at several levels of thoughts and to understand this oxides complex lies in the fabrication. Vanadium dioxide is usually synthesized by means of Chemical Vapor Deposition (CVD)‚ Physical Vapor Deposition (PVD)‚ and sol-gel method. The synthesized method depends on the physical and chemical properties and stoichiometry. The film morphology is influenced by the phase transition characteristic. VO2+ are homologous series VnO2n−1 (3

These impediments influence strongly the process of photosynthesis which rate declines sharply. Also the leaves of the trees have an important role in retention of the particulate matters; they are mostly affected when the wet and dry atmospheric deposition increase. The vegetation plays an important positive role in atmospheric purification and air pollutants reduction. The primary producers represented by plants are an important component in biogeochemical cycles. The vegetation made exchanges with

J Deleted Scenes: Richard II and the Deposition Two conflicting theories of monarchic authority arose during the Elizabethan Era‚ both finding their way into various works of literature‚ including William Shakespeare’s Richard II‚ denoting what gave a monarch the right to rule or to claim the throne. The first‚ divine right‚ describes that God directly instills the monarch with power to carry out the will of God

texture to the surface of implants‚ sandblasting and acid etching have far surpassed the others in osseointegration. Some of the others that have been tested are spray plasma coating‚ dip coating ‚ laser pulse‚ ion implantation‚ chemical vapor deposition and hydrothermal hot pressing. It is shown that bioactivity of a material can be predicted from the apatite development on its surface. Surface conditions‚ such as roughness‚ surface change ‚ surface energy and chemical composition have essential

Thin films of Pb(S‚Se) [lead sulfoselenide] have been prepared on glass substrate at 50°C by simple chemical bath deposition technique. The starting materials used for deposition were lead acetate‚ tri-sodium citrate‚ sodium sulphite and elemental selenium. Ammonium hydroxide solution was used to adjust pH of the bath. In order to obtain good quality thin films‚ time‚ deposition temperature and pH of the solution were optimized and they are found to be 1 hour‚ 50°C and 10 respectively. Characterization

CROSS EXAMINATION The party who calls a witness examines the witness with a view to adducing evidence in proof of his case and this is what is referred to as examination in chief covered at S. 145(1) thereafter the adverse party has a right to examine that witness. If the adverse party exercises that right‚ the examination is referred to as cross-examination Section 145(2). Cross examination is a fundamental right not a privilege and if a person is denied the right‚ the denial can vitiate the

phase consists of different subphases‚ which can last up to 4 weeks in the clean and uncontaminated wound. These sub phases do not happen in discrete time frames but constitute an overall and ongoing process. The sub phases are "fibroplasia‚ matrix deposition‚ angiogenesis and re-epithelialization" (Cho & Lo‚ 1998). The first sub phase of granulation process is fibroplasia. In days 5-7‚ fibroblasts have migrated into the wound‚ laying down new collagen of the subtypes I and III. In normal wound
