the photocatalytic process using semiconductors with a nanostructure is one of the technologies usedfor the destructive oxidation of organic compounds such as surfactants. in this paper, thephotocatalytic degradation of cetyl pyridinium chloride (cpc), was investigated in aqueous phaseusing various semiconductors such as titanium dioxide (ti02), zinc oxide (zno), stannic oxide(sn02). the degrad...

ARTICLE INFO ______________________________________________________________ ______________________ Introduction: The study was aimed to assess the presence of actual differences between the objective and the perceived magnitude of a curvature between patients affected by Peyronie’s disease (PD) and congenital penile curvature (CPC). Materials and Methods: Wee analysed a cohort of 88 consecutive...

BACKGROUND We studied the biological safety, biomechanics, and tissue compatibility of calcium phosphate cement and Polymethyl Methacrylate composite bone cement mixed in different ratios. MATERIAL/METHODS CPC and PMMA were mixed in different ratios (3:1, 2:1, 1:1, 1:2, 1:5, 1:10, 1:15, and 1:20). PMMA solvent is a general solvent containing a dissolved preparation of the composite bone cemen...

In this study, we fabricated nano-sized calcium silicate/poly(epsilon-caprolactone) composite (n-CPC) and micro-sized calcium silicate/poly(epsilon-caprolactone) composite (m-CPC). The composition, mechanical properties, hydrophilicity and degradability of both n-CPC and m-CPC were determined, and in vitro bioactivity was evaluated by investigating apatite forming on their surfaces in simulated...

The multibillion-dollar online advertising industry continues to debate whether to use the CPC (cost per click) or CPA (cost per action) model as an industry standard. This article applies the economic framework of incentive contracts to study the trade-o s of these pricing models. In some conditions, the CPA model leads to higher publisher (or advertiser) payo s than the CPC model. Whether pub...

The purpose of this study was to synthesize a self-setting bioactive cement by incorporation of wollastonite nanofibers (WNFs) into calcium phosphate cement (CPC). The composition, morphology, setting time, compressive strength, hydrophilicity, and degradation of WNF-doped CPC (wnf-CPC) were investigated. Scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, ...
