backgrounds and objectives:today, one of the most important environmental issues is solid waste produced in dentistry that because of the presence of hazardous, toxic and pathogen agents has special importance. in this survey, solid waste produced in hamadan dentistry laboratories and practical dentist offices is studied.materials and methods: in this descriptive study, from 24 dentistry labora...

maceutical industry for production of fine drug particles with narrow size distribution, separation of active ingredients and preparation of microemulsions and sustained drug delivery systems. Supercritical carbon dioxide (SC-CO2) is a very popular fluid for pharmaceutical applications, as it is nontoxic, non-flammable and of low cost. Furthermore, because of its low critical temperature and pr...

In this research at the first Metoprolol drug and its fullerene derivative were optimized. Natural bond orbital (NBO), nuclear Indepndent chemical shift (NICS) and finally IR calculations, for these compounds were carried out at the B3LYP/6-31G* quantum chemistry level. Different parameters such as energy levels, the amount of chemical shift in different atoms, the amount of HOMO/LUMO, chemical...

This paper intends to propose options for climate neutrality concepts by taking non-German international experiences and decisions made into account. Asia-Pacific Arabic countries do have already same lessons learned large-scale projects with regard economic evaluations. Quite a few conceptual studies generate the of chemical–pharmaceutical industry in Germany been published recently. Most diff...
