Herein, we report multi-element doped Type-II heterostructure assembly consists of N, S doped TiO2 and ZnO for electrochemical crystal violet dye degradation studies. Electrochemical measurements were performed on these synthesized N-S codoped TiO2/ZnO compositeheterostructured assemblies which are fabricated on Titanium (Ti) substrate. It was observed that a composite ele...
abstract target-oriented approaches to translation studies are regarded as recent theories of translation. one of the most famous theories among these approaches is descriptive translation studies presented by toury (1995). this theory gives a new dimension to translation studies and gives importance to the descriptive rather than prescriptive studies. it also identifies three sets of transla...
Erythromycin A (1), a well-established macrolide antibiotic, is unstable under acidic conditions. When administered orally, 1 is in equilibrium with its 8,9-anhydro-6,9-hemiketal and is simultaneously converted directly to the antibacterially inactive 6,9:9,12-spiroketal1}. A number of research groups in recent years have prepared new derivatives of erythromycin A by modification of the functio...
Repeated measures degradation studies are used to assess product or component reliability when there are few or even no failures expected during a study. Such studies are used to assess the shelf life of materials and products. We show how to evaluate the properties of proposed test plans needed to identify statistically efficient tests. We consider test plans for applications where parameters ...
Drylands occupied a large area of lands on Earth and a large percentage of the population are living in these areas. Land degradation or desertification is one of the biggest problems in arid zones. In general, little effort for mapping land degradation at regional to global scales has been made. Recent efforts to assess desertification in Iran led to devise the Iranian Model of Desertification...
