In Difco nutrient broth, containing 0.5 per cent NaCl, pH 6.6, Escherichia coli phages T1, T2, and T5 were inactivated at 66 degrees C., and T7 at 60 degrees C., at nearly the same rate. In each case the rate of destruction was not uniform but more or less decreased with time of heating. With T2 there was an initial increase in number of infective centers after heating for several minutes at 66...
Statement Problem: A few studies have been conducted about bioglass posts.Aim: The aim of this study was to compare bioglass posts with prefabricated metallic posts in clinical performance of extensive composite restorations for anterior endodontically treated teeth. Materials and Methods: Sixty endodontocally maxillary anterior teeth, with horizontally or vertically destruction, were selected....
in this paper, the optimal location and characteristics of tadas dampers in moment resisting steel structures, considering the application of minimum number of tadas dampers in a building as an objective function and the restriction for destruction of main members is studied. genetic algorithm in first generation randomly produces different chromosomes representing unique tadas dampers distribu...
Exergy destruction in adiabatic pipeline flow of surfactant-stabilized oil-in-water emulsions is investigated in five different diameter pipes. The dispersed-phase (oil droplets) concentration of the emulsions is varied from 0% to 55.14% vol. The emulsions are Newtonian in that the viscosity is independent of the shear rate. For a given emulsion and pipe diameter, the exergy destruction rate pe...
INTRODUCTION Progression of joint destruction in rheumatoid arthritis (RA) is partly heritably; 45 to 58% of the variance in joint destruction is estimated to be explained by genetic factors. The binding of RANKL (Receptor Activator for Nuclear Factor κ B Ligand) to RANK results in the activation of TRAF6 (tumor necrosis factor (TNF) receptor associated factor-6), and osteoclast formation ultim...
Modern brutality, which found its culmination in using weapons of mass destruction (WMD) against humanity, is the dark side of the principal teachings of the Enlightenment. The great thinkers of the Enlightenment, blaming religion as the main source of violence, removed God from the center of Western political and social thought to replace it with human. Although they were not conscious of the ...
abstract desertification could cause reduction of the ecological and biological potential of land which may occur both naturally and artificially. identifying and evaluating the effective factors in development of desertification is very important for better management of land. the aim of this research is to evaluate the sensitive input parameters in the desertification condition by using of ar...
this descriptive study is carried out to determine the effectiveness of family planning programmes in iran for years 1991-96. the study revealed the following outlines: contraceptives prevalence rates increased from 42% to 67% during years 1991-96. zaro couples years of protection increased for norplant, injectable contraceptive, iud, vasectomy and tubectomy, but for candom it is decreased in y...
Bone metastasis is the most frequent type of distant metastasis in nasopharyngeal carcinoma (NPC). In this study, we investigated the correlation between the skull base bone destruction and the distant bone metastasis in patients with NPC. A total of 449 cases with NPC who were diagnosed and had definitive radiotherapy from 2001 to 2006 were enrolled in this study. The skull base bone destructi...
