In this work we study the effect of some electrical prosperities on synthetic rubber reinforced with carbon black diluted in heptanes with concentrations from 0.2% gm/mole to 2.0% gm/ mole in temperatures range (100, 150, 200, 250, 300) C associated with amount weight of black carbon 5wt% added to the diluted rubber. The results of electrical properties measurement of Buna rubber reinforced wit...

Abstract Background Surgical Site Infections (SSIs) are among the leading causes of postoperative complications. This study aimed at investigating epidemiologic characteristics orthopedic SSIs and estimating under-reporting registries using capture-recapture method. Methods study, which was a registry-based, cross-sectional one, conducted in six educational hospitals Tehran during one-year peri...

Abstract: So far, too little attention has been paid to total burden of healthcare associated infections (HAIs) in Iran. In present study, we aimed to assess the rate of HAIs, as well as economic burden of hospitalization and antibiotic related cost associated with HAIs at training Taleghani hospital in Iran and to compare our results with NNIS system. This research to date for the first time h...

Monitoring the extent to which wildlife is exposed broadly used neonicotinoid insecticides (NNIs) essential assess their potential negative effects on biodiversity. Birds are good subjects such exposure, because they inhabit various habitats and feed at different trophic levels. However, so far, most studies have focused contamination of granivorous species. In this study, we concentrations fiv...

In this paper, utilization of clustering algorithms for data fusion in decision level is proposed. The results of automatic isolated word recognition, which are derived from speech spectrograph and Linear Predictive Coding (LPC) analysis, are combined with each other by using fuzzy clustering algorithms, especially fuzzy k-means and fuzzy vector quantization. Experimental results show that the ...

Three strains of facultatively anaerobic thermotolerant and moderately halophilic bacteria were isolated from two Jordanian hot spring locations. The novel Bacillus strains were short rods, Gram-positive, motile and spore formers. The strains were capable of anaerobic (but not aerobic) growth at 63C, moderately halophilic, able to grow at NaCl concentration range of 12 15 % and at temperatures ...

The Minimum Evolution (ME) approach to phylogeny estimation has been shown to be statistically consistent when it is used in conjunction with ordinary least-squares (OLS) fitting of a metric to a tree structure. The traditional approach to using ME has been to start with the Neighbor Joining (NJ) topology for a given matrix and then do a topological search from that starting point. The first st...

BACKGROUND/AIM Active surveillance is an important component of surgical site infection (SSI) reduction strategy. The aim of this study was to analyze and compare SSI surveillance data in orthopedic patients in the Military Medical Academy (MMA), Belgrade. METHODS A 4-year prospective cohort study was performed to identify the incidence rate and risk factors for SSI in orthopedic patients in ...
