Background: Tumor-like overgrowth lesions of the oral mucosa are pathological growths that project above the normal contour of the oral surface. A practical classification can be made according to the site of origin, the etiology and the histological appearance. The aim of this article is to evaluate and analyze patients with gingival and alveolar ridge tumor-like overgrowth lesions in terms of surgical treatment, diagnosis and outcome. Materials and Methods: Patients complaining of these lesions were treated by surgical excision under local or general anesthesia; the excised lesions were submitted for histopathological examination, during the follow up period the patients were examined for complications and recurrence. Results: Pyogenic gr

considered for automotive industry. In this work mechanical properties of friction stir spot welded joints were investigated for ISO(426/1CuZn10) copper alloy. The effect of main welding parameters were studied including, welding tool rotational speed, preheat time (15, 30)s , plunging time (10,30)s , dwell time 10 s ,plunging depth (0.7,0.8) mm. Group of matrices of welding parameters were used to study the effect of each parameter on properties of welded joints. Series of (FSSW) experiments were conducted using manual drilling machine. Effect of welding parameters on mechanical properties of welded joints were investigated using tensile

Absorption, fluorescence, quantum yield and lifetime of rhodamine 6G in chloroform, methanol and dimethyl sulfoxide were measured. From a comparison of these quantities, with those for solid solutions (solid solutions are obtained by mixing constant volume proportions of dye at a concentration of 1*10-4M/l with different volume proportions from the concentrated solution of polymer in chloroform and dimethyl sulfoxide). The results showed that the addition of polymer to liquid concentrated solutions (1*10-4M/l )of rhodamine 6G dye from expecting [which leading to development active medium for laser dye at high concentration] increase the spectra shift toward high energies, and the luminescence quantum yield but decreasing radiative lifetim
