Objective: To study the effects of Tumor Necrosis Factor-α (TNF-α) and anti-TNF-α Monoclonal Antibody (McAb) in myocardial injury of rats with traumatic hemorrhagic shock. Methods: Twenty-four adult male Sprague-Dawley (SD) rats were randomly divided into the control group (A1 group), lactate Ringer's solution resuscitation group (A2 group) and anti-TNF-αMcAb resuscitation group (A3 group). A k...

Recursive spectral bisection (RSB) is a heuristic technique for finding a minimum cut graph bisection. To use this method the second eigenvector of the Laplacian of the graph is computed and from it a bisection is obtained. The most common method is to use the median of the components of the second eigenvector to induce a bisection. We prove here that this median cut method is optimal in the se...

Researchers aim to make the strongest possible conclusions from limited amounts of data. To do this, they need to overcome two problems. First, important differences in the fi ndings can be obscured by natural variability and experimental imprecision. Thus, it is diffi cult to distinguish real differences from random variability. Second, researchers’ natural inclination is to conclude that diff...

The aim of this study was to estimate the prevalence subclinical mastitis (SCM), its innate immunity and compare efficacy indirect diagnostic tests [California test (CMT), differential electrical conductivity (DEC), absolute EC, enzyme based color detection method (Tanucheck kit) brothymol blue strip (BTB) tests] milk somatic cell count (SCC) using 200×103 cells/ml as a cut off value in Deoni (...

maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. when this is the case, the price of the product has a critical effect on optimum value of cut-off grade. this paper investigates the relationship between optimum cut-off grade and price to maximize total cash flow and net percent value (npv) of operation. in order to visualize this ...

in this paper, we study an equivalence relation on the set of fuzzysubgroups of an arbitrary group g and give four equivalent conditions each ofwhich characterizes this relation. we demonstrate that with this equivalencerelation each equivalence class constitutes a lattice under the ordering of fuzzy setinclusion. moreover, we study the behavior of these equivalence classes under theaction of a...

This study aims to analyze psychometric properties and validity of the Compulsive Internet Use Scale (CIUS) and the Internet Addiction Test (IAT) and, second, to determine a threshold for the CIUS which matches the IAT cut-off for detecting problematic Internet use. A total of 292 subjects with problematic or pathological gambling (237 men, 55 women) aged 14-63 years and with private Internet u...
