Cops and robbers is a vertex-pursuit game played on graphs. In the classical cops-and-robbers game, a set of cops and a robber occupy the vertices of the graph and move alternately along the graph’s edges with perfect information about each other’s positions. If a cop eventually occupies the same vertex as the robber, then the cops win; the robber wins if she can indefinitely evade capture. Aig...

One hundred and ninety eight samples of human and animal sources from different areas in El-Sharkia Governorate were used in this study to isolate Staphylococcus species and to determine the presence of coagulase ( coa) gene,a virulence gene detected in S. aureus (CoPS), by PCR. Primary isolation on mannitol salt agar, $-haemolysis, tube coagulase test (TCT) and other biochemical characterizati...

This study examined the effect of adding antioxidants, namely curry leaf extract (CLE) and butylated hydroxyanisole (BHA), on physicochemical properties ghee during deep frying. The results showed that addition CLE to resulted in significant changes L*, a*, b* values, likely due extraction chlorophyll molecules preparation. Deep frying caused a decrease L* values an increase a* ghee, as well re...

Business strategies and index evaluations on communities of practice (CoPs) could be the prevailing way for group learning and innovation building within firms. As firms grow in size, scope, and complexity, CoPs members who regularly engage in sharing and learning based on common interests, could improve organizational performance. Due to multi-criteria consideration and uncertain information h...

This study investigated the effects of cooking methods on the digestibility of lipids and formation of cholesterol oxidation products (COPs) in pork, during in vitro human digestion. Pork patties were cooked using four different methods (oven cooking, pan frying, boiling, and microwaving), to an internal temperature of approximately 85℃. The digestibility of pork patties were then evaluated, us...

Nontyphoidal Salmonella enterica serovars Enteritidis and Typhimurium are a common cause of gastroenteritis but also cause invasive infections and enteric fever in certain hosts (young children in sub-Saharan Africa, the elderly, and immunocompromised individuals). Salmonella O polysaccharides (OPS) and flagellar proteins are virulence factors and protective antigens. The surface polysaccharide...

The Nuclear Medicine Technology Certification Board presents Components of Preparedness Statements (COPS) to accompany its recently revised task list. The COPS expand the tasks identified as important to the practice of nuclear medicine technology. These tasks are developed through an extensive process called a task analysis, which is reviewed in the article. The COPS represent the final step i...
