An Autogenous Milling defined as used in this study, the term Autogenous milling means a process in which the size of the constituent pieces of a supply of rock is reduced in a tumbling mill purely by the interaction of the pieces, or by the interaction of the pieces with the mill shell, no other grinding medium being employed. The definition thus covers both 'run-of-mine' and 'pebble' milling, the only difference from the mathematical modeling viewpoint being that the feed to the first has a continuous, and the second a non-continuous, size distribution. This paper describes the detail design of a typical Autogenous mill.

With increasing development companies around the world, our country Iran is not an exception and keep pace with this development according to the conditions prevailing in different fields expanded, The telecommunications compliance with Article 44 of the constitution And move towards privatization of the state monopoly in the This leads to emerging operators with strong potential for the days that involved the complex challenge This development has lagged behind and competitive with others in order to survive in the market are at an acceptable level of service to its customer’s In this regard, in addition to rely on the equipment and infrastructure facilities need a strong financial system for the preparation of financial information for users outside the organization Such as the tax country or shareholders and a strong financial system for the management of the company are domestic users For the analysis of financial data to make better decisions than the development or production of certain outdated act according to its earnings In addition to pricing and decisions regarding the production and sale to a financial system warning that the value of finished goods is needed Because the value of finished products in different times and conditions may differ In this regard, due to the lack of Production system cost in telecommunications company we decided to design cost model is based on the financial coding system that includes all Specific, detailed and coding functions to achieve cost in different areas of the province, So in various parts of the cost of the product to be obtained separately.

A simple, accurate, rapid and precise isocratic reversed-phase high-performance liquid chromatographic method has been developed and validated for simultaneous determination of Metformin and Gliclazide in tablets. The chromatographic separation was carried out on an Cosmosil ODS analytical column (250×4.6 mm; 5?m) with a mixture of Methanol: Hplc grade water pH 6 adjusted with Orthophosphoric acid(70:30, v/v) as mobile phase; at a flow rate of 1 ml/min. UV detection was performed at 235 nm. The retention times were 2.50 and 6.02 min. for Metformin and Gliclazide, respectively. Calibration plots were linear (r2>0.998) over the concentration range 5-30?g/ml for Metformin and 1-6?g/ml Gliclazide. The method was validated for accuracy, precision, specificity, linearity, and sensitivity. The proposed method was successfully used for quantitative analysis of tablets. No interference from any component of pharmaceutical dosage form was observed. Validation studies revealed that method is specific, rapid, reliable, and reproducible. The high recovery and low relative standard deviation confirm the suitability of the method for routine determination of Metformin and Gliclazide in bulk drug and tablets dosage form.

At present mono crystalline silicon solar cells are more established and mostly used to generate electricity rather than using thin films crystalline silicon solar cells, amorphous silicon solar cells, because they attain less efficiency. Improvement in efficiency of mono crystalline silicon solar cells is very much relevant today from the point of view of cost reduction. Some of the very promising approaches for efficiency improvement for conventional silicon solar cells manufactured with screen printing technology are modification in the existing screen printing, Al BSF process, selective emitter, back surface passivation, HIT cells, multilayer Anti-reflection coating and other technologies etc. These technologies boost the efficiency of a solar cell by 1-2%. This paper discussed and investigated for improving efficiency in mono crystalline silicon solar cells with uniform texturization, multilayer ARC, front grid optimization, metallization and increasing aspect ratio which decreases shadow effect and also lowers the series resistance, in the manufacturing process of mono crystalline silicon solar cells.
