Design and test models the sufficiency of two savers can be used for preservation the tomatoes

The research aims to optimize the investment in solar cooling process using two models of vessels (clay- mineral).The study was conducted at the site of Tartous in the month (the fourth - fifth - sixth) years (2013) and that the fruits of the tomato study, she stated that the pottery is causing a drop in temperature between )4-6( degrees Celsius, and that the metal causes the low temperature range between (3-5 ) degrees Celsius although the fruits of tomatoes preserved pottery vessels have not undergone any damage of its structure or texture during the period of conservation (27 days) compared to the control which is exposed to damage during the (12 days) .

Direct Application of composite Veneers & Lumineers by modified metal matrix

These days compositedefinitly became at the top of direct cosmetic restorations, and the most using restorative material, due to this development now it's used for direct Veneers &Lumineers. Because of the high sensitivity of its application, general practitioner should achieve a dry, clear work field, especially gingival area. The aim of the study was to use the modified metal matrix, which used in this study, is to retract the gum, isolate the tooth from the exudation of the sulcus and bleeding gum avoiding margin leakage, also provide acceptable continuance between the restoration surface and the under gum tooth structure, to prevent forming reverse stage under gum. 120 teeth were included in this study, all teeth were treated using the modified metal matrix, 10 teeth at least for each patient, with no orthodontic treatment. The results have practically proved getting all goals; retracted gum, tooth isolated from exudation of the sulcus and bleeding gum, also provided continuance between veneers and under gum tooth structure, and not having reverse stage which is the main cause of gum inflammation, beside time saving and easy direct veneer application.
