Abstract Background Active surveillance tests for carbapenemase-producing Enterobacteriaceae (CPE) are recommended in patients showing risk factors colonization by these bacteria. There limited data however on whether anatomic sites other than the stool would be useful to detect CPE colonization, and we investigated this our present study. Methods Retrospective analysis was performed cases at t...

We solve the Dirac equation in one space dimension for the case of a linear, Lorentz-scalar potential. This extends earlier work of Bhalerao and Ram [Am. J. Phys. 69 (7), 817-818 (2001)] by eliminating unnecessary constraints. The spectrum is shown to match smoothly to the nonrelativistic spectrum in a weak-coupling limit. 3.65.Pm, 3.65.Ge Typeset using REVTEX 1
