THIS book quickly reveals to anyone who has to see such injuries the wide experience and skill that the authors have to draw on. It is full of helpful clinical and practical operative advice where this is sought, but the real message of this edition seems to be encouragement to undertake more meticulous and extensive primary repairs. The classification of hand wounds into "Tidy and Untidy" imme...

  Background: Health care workers occupationally are exposed to blood and other body fluids which might increase their risk of acquiring blood-borne pathogens and psychological stress . The aim of the present study was to determine the lifetime occupational exposure to needlestick injuries and body fluids among doctors and medical students in Rafsanjan University of Medical Sciences (2009)...

background: post-exposure prophylaxis plays an important role in prevention of bloodborne diseases after occupational exposures. objective: to evaluate the knowledge, attitude and practice of dentists towards post-exposure prophylaxis. methods: in a cross-sectional study, 140 dentists in shiraz were selected through a systematic randomized sampling. they filled out a self-made questionnaire inc...

in this work, we report high biological performance of silicon substituted nano hydroxyapatite (nha) prepared by immersion of calcium phosphate and sodium silicate as precursors in simulated body fluid (sbf) solution for 24, 36, 48 and 72 hrs at 37°c. characterization and chemical analysis of the synthesized powders were performed by fourier transform, infrared spectroscopy (ft-ir), x-ray powde...

Titanium and zirconium were immersed in Hanks’ solution with and without calcium and phosphate ions, and the surfaces were characterized with X-ray photoelectron spectroscopy (XPS) to determine the mechanism of calcium phosphate formation on titanium in simulated body fluids and in a living body. In addition, they were cathodically polarized in the above solutions. As a result, neither calcium ...

Molecular dynamics simulation has been used to model pattern formation in three-dimensional Rayleigh-Bénard convection at the discrete-particle level. Two examples are considered, one in which an almost perfect array of hexagonally shaped convection rolls appears, the other a much narrower system that forms a set of linear rolls; both pattern types are familiar from experiment. The nature of th...

Electrorheological (ER) fluids change their flow properties dramatically when an electric field is applied. These fluids are usually composed of dispersions of polarizable particles in an insulating base fluid or composed of liquid crystal polymer. To build more suitable and complicated designs for application of ER fluid, the simulation of ER fluid as well as experiments are important. First, ...
