The aims of the study were to observe the dissolution profile of four types of selected fruit powder fast dissolve tablet and apply different dissolution profile comparison methods, in order to select most applicable method. Spray dried powder of pitaya, pineapple, guava and mango were used as raw material. Each type of fruit powder tablet has identical dissolution profile. Dissolution profiles...

The aims of this study were to evaluate the effects of CPP method on the crystallinity of apatite powder and on the acid resistance of bovine enamel. Crystallinity degrees of apatite powder before and after CPP treatment were measured by powder X-ray diffraction analysis. Polished bovine enamel specimens treated with CPP method or NaF were immersed in a lactic acid solution for up to five days....

OBJECTIVE To evaluate the air powder abrasive treatment as an implant surface cleaning method for peri-implantitis based on the existing literature. MATERIALS AND METHODS A PubMed search was conducted to find articles that reported on air powder abrasive treatment as an implant surface cleaning method for peri-implantitis. The studies evaluated cleaning efficiency and surface change as a resu...

To detect urea content in milk powder, a nonlinear chemical fingerprint technique was developed. In our study, Belousov-Zhabotinsky oscillatory chemical reaction (B-Z) was performed using milk powder and malonic acid as main dissipative substances. The same dosage of milk powder with or without artificially added urea was introduced to “H+ + Ce4+ + 3 BrO − + malonic acid” oscillating system, re...

A rapid and simple procedure for the determination of non-stoichiometric oxygen in YBa2Cu3O7 d (YBCO) superconductors is described, based on the relationship between oxygen content and c-axis parameter of the YBCO structure. To test the proposed method the oxygen content of samples sinterised starting from different precursors has been calculated from X-ray powder diffraction analysis and compa...

The present study was carried out to evaluate the in vitro antimicrobial and antioxidant activity of Emblica officinalis juice powder. The antimicrobial activity was assessed against gram positive and gram negative bacteria namely E.coli, Pseudomonas fluoresces, Bacillus subtilis, S.aureus, and fungi namely Aspergillus niger, Penicillium chrysogenum, Alternaria alternata, and Fusarium spp by ag...
