nosocomial infection caused by methicillin-resistant staphylococci poses a serious problem in many countries. the aim of this study was to rapidly and reliably detect methicillin-resistant-staphylococci in order to suggest appropriate therapy. the presence or absence of the methicillin-resistance gene in 115 clinical isolates of staphylococcus aureus and 50 isolates of coagulase negative staphy...

Some identities of the k-Pell-Lucas sequence and their relationship to the Modified k-Pell sequence allow us to obtain some identities for Modified k-Pell numbers. Also the ordinary generating function for the Modified k-Pell sequence and another expression for the general term of the sequence, using the ordinary generating function, is provided. Mathematics Subject Classification 2010: 11B37, ...

Cluster examination is data mining task for the assignment of collection a set of items in such a path, to the point that questions in the same gathering (called a cluster) are more like one another than to those in different gatherings (clusters). K-means grouping is a technique for group investigation which intends to parcel n perceptions into k groups in which every perception fits in with t...

a simple method has been developed for the preconcentration of copper(ii) based on the adsorption of its modified nano polyacrylonitrile fiber. modified nano polyacrylonitrile fiber (panf) was prepared by adding of acrylic fibers to msethanolamine (mma) with different concentration solutions. the stability of a chemically modified nano polyacrylonitrile fiber especially in concentrated hydrochl...

The present work concerns with an investigation on the solubility of cis,cis-muconic acid dissolution in different polar solvents by characterizing and modeling the dissolution as a function of temperature. Water, ethanol, 2-propanol and acetic acid have been investigated as solvents in the range temperatures from a 298.15 to 348.15 K. Owing to the absence of cis,cis-muconic acid solubility...
