In this paper, the flow characteristics of polishing fluid between pad and workpiece are studied for robotic wet process. The distribution radial velocity Ur liquid film thickness z at different rotating radii r is revealed. two-dimensional computational domain consisting surface, wall, established. particle-liquid two-phase simulation carried out in Fluent. influence rotation rates ω robot swi...

occupational exposure to blood and body fluids is an important hazard for health care workers, which places them at a high risk for blood-borne infections including hepatitis b virus, hepatitis c virus and human immunodeficiency virus and results in psychological and emotional stresses. several preventive measures have been proposed including pre-exposure ( e.g. , education, use of standard pre...

physiologists have shown that increased fluids improve skeletal muscle performance in prolonged exercise.typical orders provide for 125 ml of intravenous fluids per hour in patients taking limited oral fluids during labor. our purpose in this study was to determine whether increased intravenous fluids affect the progress of labor. in a prospective randomized institutional clinical trial, one-hu...

  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: the purpose of the present study was to examine the reliability of scapular kinematic measurements using motion analysis system in subjects with and without general hypermobility syndrome. methods: a methodological study was designed to assess the reliability of scapular movement measurement in two groups of females with and without general hypermobility syndrome. upward rotation, s...

conclusions the results of this meta-analysis show that colloid fluids can increase the successful resuscitation rate compared to crystalloid fluids especially in traumatic and hypovolemic patients.some of the colloids like albumin and dextran have a positive effect on reducing the mortality rate but others like hetastarch (hes) increase the mortality rate compared to normal saline (ns). result...

The thermodynamic properties of fluids can be predicted using the global equations of state. Among these thermodynamic properties of fluids, we choose the densities of the liquid and vapor phases. This paper considers the application of the crossover model to the vapor-liquid rectilinear diameter of sulfurhexafluoride. We also present a comparison of the crossover model equation with ...
