The characteristics of the synchrotron radiation generated by an electron beam in bending magnets, planar undulators and wiggler magnets are derived, with emphasis on the spectral flux, brilliance, and power densities. The interaction of the electron beam with the insertion device field is discussed in terms of closed orbit distortion, tune shift and non-linear effect. The technology of permane...

A necessary and sufficient condition in terms of lower cut sets are given for the insertion of a $gamma-$continuous function between two comparable real-valued functions.

background and objectives: enteropathogenic escherichia coli (epec) divided into two groups typical and atypical (aspect). the main virulence genes are located in a pathogenicity island called lee ( locus of enterocyte effacement ). lee frequently inserted in trna genes of selc , pheu and phev in the bacterial chromosome. tepec and aepec strains have some differences in their pathogenicity. the...

background and objectives: enteropathogenic escherichia coli (epec) strains can be detected by serogrouping and the presence of enterocyte attaching- effacing (eae) gene. most epec strains belong to a certain o antigenic group. locus of enterocyte effacement (lee) pathogenicity island contains the eae gene and secretory proteins (esps) that introduce the attaching-effacing lesion. lee inserted ...

conclusions evidence-based post-insertion recommended care practices were not consistently and uniformly implemented in the intensive care units. establishment of a program for the surveillance of adherence to recommended guidelines is required for improving compliance by health professionals and the quality of preventive care. background healthcare-associated infections (hais) are acquired by ...
