Calculations using the quantum-chemical semiempirical AM1 method for modeling reaction between methyldimethoxysilane [Me(MeO)(2)SiH] and 5-vinyl-2-nor-bornene were performed to evaluate possible reaction paths. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 120: 1572-1582, 2011″
“We describe a technique to manage dense cataract cases After a capsulorhexis of 6.0 to 7.0 mm diameter has been created, the phaco tip is inserted into the nucleus centrally and high vacuum is used to lift the nucleus and elevate it with a tilt to protrude outside the capsular bag distally The chopper is used to segment the nucleus centripetally, starting from the lens equator or just
behind, without applying stress to the capsular
bag or zonules Further Sapanisertib manufacturer phacoemulsification is maintained I-BET-762 by holding the nucleus centrally and chopping it into smaller triangular sectoral pieces. In this horizontal chopping technique, which is done just outside the capsular bag, grasping the nucleus in the center and elevating it with high vacuum instead of depressing one edge of the nucleus to elevate the other edge prevents additional stress to the capsule and zonules.”
“Durable curcumin-treated antibacterial polyethylene terephthalate (PET) fabrics (against Staphylococcus aureus) were produced by dyeing with curcumin after surface activation using vacuum ultraviolet excimer lamp at 172 nm. Surface change properties of the exposed fabrics were characterized by surface analysis methods such as wettability, atomic force microscopy, and X-ray photoelectron spectroscopy. Results show an increase in surface hydrophilicity with a water contact angle of the PET fabric reaching 24 degrees after 10 mm excimer irradiation, which could be attributed to an increase in carboxyl group formation as confirmed buy BKM120 by X-ray
photoelectron spectroscopy measurements. Varying concentrations of curcumin were immobilized onto untreated and vacuum ultraviolet-irradiated PET samples using diffusion method at 90 degrees C, and the treated fabrics characterized using K/S (color strength) values at 440 nm. K/S values increased when the PET surface was subjected to a prior excimer irradiation, because of grafting of curcumin at the PET surface. Increased excimer irradiation time increased grafting of curcumin because the inner fabric fiber surfaces were also more thoroughly treated. (C) 2010 Wiley Periodicals, Inc.

“In this paper the smallest or optimal dimensions of a Halbach cylinder of a finite length for a given sample volume and desired flux density are determined using numerical modeling and parameter variation. A sample volume that is centered in and shaped as the Halbach cylinder bore but with a possible shorter length is considered.
