the aim of this study is experimental assay of sensitivity and stability of a bimetallic silver/gold spr sensor chip. this chip utilizes the sensitivity of the silver and the stability of the gold. moreover, the silver layer (instead of usual cr or ti layer) was used as an adhesive intermediate layer between the gold layer and the glass substrate. the optimization of the gold/silver thickness u...

According to the unique properties and many applications of nano gold powder, it was prepared from an acid leaching tail solution. The low value residual gold ions existed in acid leaching tail solution in Mouteh gold mine in Iran with fellow heavy metals as pollutants (Fe2+, Cu2+, and Zn2+). Preparation of nano gold particles is achieved by two steps: First, by addition of ammonia as separatio...

Painting on walls is the final stage process after sprinkling and plastering walls. functions as beauty in a building. In addition to functioning an aesthetic beauty, painting wall can also be used protection from rain splashes direct sunlight that shorten life of wall. First prepare tools materials for Supervision required so work or accordance with Regulation Minister Public Works The Mainten...

In a study at Helena; Arkansas, sprinkling hardwood logs during summer storage greatly reduced degrade caused by stain and insects. Logs of four Southern species were stored for 16 weeks starting July 18, 1962. The study was conducted cooperatively by the Southern Hardwoods Laboratory and the Chicago Mill and Lumber Company. While Western softwood and Northern hardwood mills have been using thi...

Since a high toxicity of cyanide which use as a reagent in the gold processing plant, thiosulfate has been recognized as a environmental friendly reagent for leaching of gold from ore. After gold leaching process it's important for recovery of gold from solution using adsorption or extraction methods, One of these methods is activated carbon.The loading of gold from industrial thiosulfate solut...

We consider a class of of massless gradient Gibbs measures, in dimension greater or equal to three, and prove a decoupling inequality for these fields. As a result, we obtain detailed information about their geometry, and the percolative and non-percolative phases of their level sets, thus generalizing results obtained in [24], to the non-Gaussian case. Inequalities of similar flavor have also ...
