The use of pulsed dc-sputtering sources for reactive magnetron sputtering with oxygen offers a possibility to suppress the negative effects target poisoning (such as arcing). This results in wide process range selection desired operating point. control plays major role maintaining constant coating properties and affects stoichiometry coating, well rate economic impact process. In hysteresis, du...
This research proposes the effect of temperature variation in the Prandtl number on the power, the efficiency and the heat loss of the Gama-type Stirling engine. It should be noted that the Prandtl number included the viscosity, the thermal conductivity coefficient and the specific heat at constant pressures of the working fluid, which the temperature dependency of such first two thermo-dynamic...
In the present work, we have synthesizedgadolinium(III) bromide, GdBr3 from the gadolinium oxide, Gd2O3 by sintering brominating with ammonium bromide, NH4Br. The influence of three main synthesis parameters (contact time, stoichiometry, and temperature) on the reaction yield was studied and optimized. This study showed that the optimum conditions...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
feminine voice and narratology in wuthering heights wuthering heights as a general "bronte" work has extraordinary dimensions to it which can make it focal to different ways of interpretation. among other differences the issue of narrative voice is essential in understanding the ultimate purpose of wuthering heights. emily bronte uses different narrators from various focal points speaking of m...
in the crystal structure of the title polymeric compound, [c42h38n6o33sr5.2(h2o)]n, five independent metal atoms (sr1-sr5) have different coordination environments. the sr1 and sr5 atoms are nine coordinated and feature distorted tricapped trigonal-prismatic and capped square-antiprismatic geometries, respectively. the rest srii atoms have eight coordination numbers. these units are connected v...
Surface charge of mixtures of lepidocrocite and i\lite determined by adsorption of potentia l-determining and electrolyte ions is studied as a functi on of pH and NaCI concentration. Deviations between results oblained by both methods were a fu nction of the ill ile content of the mixtures, and can be mainly attributed lO coatings of hydroxyalum inium compl exes on the constant charge surfaces ...
