The dissolution rate of Iron and Titanium from Syrian basalt rock was studied by hydrochloric acid, sulfuric acid, mixture of hydrochloric acid methanol, sulfuric acid methanol solutions. The effects of temperature, time of digesting and concentrations of acids have been investigated, the ratios of solid to liquid and stirring speed were constant (S/L=0.02). It has been clear that when the mixture of hydrochloric acid and methanol (100:50(V:V) HCL:CH3OH) was used, the best dissolution for both iron and titanium was obtained when we digested the rock and it took 6h at 100 ˚C where as the concentration of hydrochloric acid and methanol were [HCl]=11M, [CH3OH] =0.92M, the resulting ratios of dissolution of iron and titanium in the mentioned conditions were 75.53%, 63.19 % respectively.

The research was conducted at the poultry farm in Kharabo, Faculty of Agriculture, Damascus University. 1080 chicks of Lohman hybrid, one day old, distributed randomly and equally into six different groups, G1….G6 (180 chicks/ group) with three re plicates in each group (60 chicks per replicate). Chicks in all groups were fattened for 42 days on Diets composed of vegetarian feeding stuffs, based on corn, soya bean meal and different additives. Chicks of G1 were fed on the main diet without adding iron or copper. The chicks in G2 and G3 were fed on the main diet mixed with 80 and 160 ppm of iron respectively. The vhicks of G4 were also fed on the main diet mixed with 8 ppm of copper. The Chicks of G5 and G6 were fed on the main diet mixed with iron and copper (80 and 8 ppm) and (160 and 8 ppm), respectively. Results demonstrated that adding iron and/or copper to the broiler diet was safe for chickens up to 42 days of age and did not affect significantly on carcass parameters. Supplementation of broiler diet with 8 ppm of copper was not associated with accumulation of copper in the tissues of liver, leg bone, breast, and thigh. Adding 80-160 ppm of iron to the broiler diets was not associated with high level of accumulation of iron in the tissues of breast and thigh but with high concentrations (p < 0.05) in the tissues of liver and leg bone.
This research includes studying and creating a modern model to convert the mechanical energy of sea waves into electrical power. This model uses wave’s mechanical energy to pump water to dam rises above sea level, which in turn can run water turbin e and get electrical energy in the conditions of Syrian coast. The search also includes a computer program written using Visual Basic.net, so that the program calculates the station according to the data of the waves in the geographical area that are selected and show the results in a clear value curves, after that we get useful proposals aims to build and develop this model at the future.
The target of this study is improving the electrical power systems performance estimation because of its importance in complex modern networks investment that have a lot of advanced equipments. Having a complete representation of the electrical sy stem makes diagnosis thing much accurate and reliable which is used in electrical networks operation and maintenance. We focus in this research on implying different conditions and factors which affect operation and we use fuzzy petri nets for that purpose because of its characteristics in handling with incomplete and uncertainty data . we make our simulation on a real diagram of a refinery to compute its truth degree and discuss the results , we match that adding changing factors at operation contribute in improving networks estimation accuracy and support decisionmaking process .
We studying in this research the reaction with Zinc sulphate in an aqueous solution by physical - chemical method in presence of Succinic Acid , and determined compounds which are formed in this solution and we calculated of it formation the const ants. After we used these electrolytes in plating by Zinc , that is by electro precipitation of this metal on the solid electrodes (steel, copper) so that we definite the best of these electrolytes for galvany and the set necessary conditions for its use.
The administrative judiciary is specialized with halting the implementation of the defected administration resolutions with unlawfulness to provide protection for people who are subject to these resolutions. However such protection requires the av ailability of several conditions which are required by the administrative judiciary lest prohibiting any abuse in halting the implementation of the administration resolutions, or disabling them without reasonable cause. As this research will introduce and discuss the concept of these conditions and their influence on halting the implementation.
