A difference in average modulation (le, optics quality) up to 15% did not produce significant differences in mean

visual acuity between 2 groups, however, there was a significant difference in mean visual acuity between 2 groups when the average modulation values differed by at least 25% The slope of the linear correlation between visual acuity and average modulation was 0.018 (r(2) = 0 91) under photopic conditions and 0.024 (r(2) = 0.089) under mesopic conditions.

CONCLUSIONS: There was a strong linear correlation between IOL optics quality and visual acuity with distance correction under photopic Cyclosporin A in vivo conditions with a pupil of approximately 3.5 mm in a cohort in which the patient age was controlled. The correlation was similar under mesopic conditions. The eye’s tolerance to modulation transfer function decay was approximately 15% of the average modulation value.”
“In this work, the effect of zinc oxide (ZnO) concentration and shape on processing and properties of new biaxially oriented polypropylene (BOPP)-ZnO nano-composites was studied. The use of spherical nanoparticles and nanorods was expected to differently influence the properties of the final material. Films of isotactic polypropylene prepared with different ZnO incorporation were biaxially oriented under conditions of temperature and strain rate that were similar to those

encountered in a commercial film process. Scanning electron microscopy analysis was performed to visualize the dispersion degree of the ZnO nanoparticles in the polymer matrix and to observe the surface and the orientation of learn more the elongated nanoparticles. Furthermore, the prepared ZnO-BOPP nano-composites Selleck GSK461364 were evaluated for both mechanical and oxygen barrier

property enhancement. A good combination of mechanical and oxygen barrier properties was obtained for the ZnO-BOPP films. This result makes the ZnO-BOPP nanocomposite a proper material for applications such as food packaging. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 120: 1616-1623, 2011″
“Since plasma parameters are altered by dust particles, studying how plasma parameters are related to dust particle growth is an important research issue in dusty plasma. In this paper, the correlation between plasma parameters (electron temperature and ion flux) and particle parameters (particle radius and density) is investigated in silane plasma both experimentally using a floating probe and theoretically by solving balance equations including an additional electron and ion loss to the dust. The results reveal that while the ion flux shows two peak values in the early discharge phase and at the end of coagulation phase, the electron temperature shows a sudden increase in the coagulation step and a gradual decrease in the molecular accretion step. Moreover, the calculated results with the secondary electron emission taken into account produce the best fit with the experimental results.
