Telecommuting has achieved recognition in several states and foreign countries as a means to reduce trip-making during the peak period. Evidence to date suggests that telecommuting can effectively eliminate commute trips without creating new travel. If true, telecommuting holds vast potential to mitigate urban traffic congestion. Decreased network fuel consumption and improved air quality are t...
Natural Convection Heat Transfer from a Heat Sink with Hollow/ perforated circular Pin Fins (Dept.M)
Flow boiling of water across a bank of circular staggered micro-pin fins, 250 lm long and 100 lm diameter with pitch-to-diameter ratio of 1.5, was experimentally studied for mass fluxes ranging from 346 kg/m s to 794 kg/m s and surface heat fluxes ranging from 20 W/cm to 350 W/cm. Local temperature measurements were used to elucidate the two-phase heat transfer coefficients. The flow was visual...
BACKGROUND Developed for the treatment of deformity correction, computer-assisted circular external fixators in recent years have also been used for fracture fixation. In this study, we aimed to present the efficacy of computer-assisted circular external fixator use in open long bone fractures with our new technique. METHODS Between February 2013 and June 2014, 14 patients (mean age 24.5 (ran...
a total of 68385 live pin-worm eggs from adhesive scotch tape were exposed to different detergent powders in under to compare method of detergent washing clothes with the boiling method for the control of family enterobiasis. results show that: a) 80.4-100 percent of eggs are destroyed after hatching within 6-8 hours of exposure to 0.25 gr% detergent at 10-250c. exposure for less than 6 hours h...
It is a common problem, radial distortion of off-theshelf cameras, especially those low-cost ones and wide-angle ones. And the most direct method to judge whether radial distortion occurs in an image is the straightness of those lines in the image, for the straight line in the image should be straight in the ideal image under the pin-hole camera model. In this paper, we present a new line-based...
Introduction: The restoration material commonly used as core material for pulpless posterior teeth is mostly amalgam due to its high strength and low cost and it can be used with or without pin. The aim of this study was to evaluate the influence of post material on stress distribution in mandibular second premolar tooth by finite element analysis. Method: The stress distribution was analyzed i...
A detailed correlative structural, magnetic and chemical analysis of non-stoichiometric cobalt ferrite micrometric crystals was performed by x-ray circular dichroism combined with photoemission microscopy, low energy electron atomic force microscopy. The vector magnetization at the nanoscale is obtained from images different incidence angles compared micromagnetic simulations, revealing presenc...
