objective: the aim of this study was to evaluate the bond strength between metal brackets and non-glazed ceramic with three different surface treatment methods. materials and methods: forty-two non-glazed ceramic disks were assigned into three groups. group i and ii specimens were etched with 9.5% hydrofluoric acid. subsequently in group i, silane and adhesive were applied and in group ii, bo...
Phosphoric acid added L-alanine (PLA) single crystals were grown successfully by slow evaporation technique at room temperature by taking 2:1 molar ratio of L-alanine and phosphoric acid. Solubility and nucleation kinetic measurements were carried out for the PLA sample. Critical nucleation parameters have been calculated. Structural analysis reveals that PLA crystal crystallizes in orthorhombi...
to teach english adequately, qualified teachers are needed. unfortunately, there are still teachers who are teaching english without an academic degree in tefl. it is necessary for teachers to have a major in english to have subject knowledge, but it is not sufficient. teachers need to have an understanding of the social, cultural, moral, ethical, and pedagogical issues of education and practic...
Degradation of rebaudioside M, a minor sweet component of Stevia rebaudiana Bertoni, under conditions that simulated extreme pH and temperature conditions has been studied. Thus, rebaudioside M was treated with 0.1 M phosphoric acid solution (pH 2.0) and 80 °C temperature for 24 h. Experimental results indicated that rebaudioside M under low pH and higher temperature yielded three minor degrada...
