A clinical Providencia stuartii isolate SM662 was recovered from a patient hospitalized in the intensive care unit at the Military hospital, Tunisia. This isolate was resistant to penicillins, cephalosporins, aminoglycosides and fluoroquinolones. A marked in vitro synergy between ceftazidime or cefotaxime and amoxicillin-clavulanic acid on Mueller-Hinton agar plates suggested the presence of an...

For complex potentials V (x) = −(ix)3 − β(ix) − 2 β δ (ix) which are PT symmetric we show that in the β ≫ 1 strong coupling regime the low lying bound states almost coincide with harmonic oscillators whenever the spectrum remains real (this means, at all δ < δcritical(β) ≈ 1).

The almost Mathieu operator is the discrete Schrodinger Hα,β,θ on \(\ell ^2(\mathbb {Z})\) defined via \((H_{\alpha ,\beta ,\theta }f)(k) = f(k + 1) - \beta \cos {}(2\pi \alpha k \theta ) f(k)\). We derive explicit estimates for eigenvalues at edge of spectrum finite-dimensional \({H^{(n)}_{\alpha }}\). furthermore show that (properly rescaled) m-th Hermite function ϕm an approximate eigenvecto...

OBJECTIVES The objective of this study was to establish how antibiotic prescribing policies at National Health Service (NHS) hospitals match the England Department of Health 'Start Smart-Then Focus' recommendations and relate to Clostridium difficile infection (CDI) rates. METHODS Antibiotic pharmacists were surveyed regarding recommendations for empirical treatment of common syndromes ('Star...

conclusions our study emphasized the increasing role of esbl genes, especially blactx-m15 in epec isolates. results of 42 epec, eight isolates carried the blactx-m1. none of the isolates carried blactx-m2 and blactx-m9. the blactx-m15 variant was identified in all of blactx-m1-positive isolates. furthermore, blashv and blatem genes were detected in 40.5% (n = 17) and 19% (n = 8) of all epec iso...

For the jet pointing towards us: the spectrum in the jet rest frame is a power law from ν1 to ν2. In the observer frame, every frequency gets Doppler shifted by D+ = γ(1 + β cos θ) > 0, where β = v/c > 0 (RL equation 4.12b). The factor of 1 + β cos θ is the usual Doppler shift (train-whistle effect), while the factor of γ arises from time dilation. So the whole forward jet spectrum shifts to hi...

β-lactamases are the primary cause of resistance to β-lactams among members of the family Enterobacteriaceae. SHV enzymes have emerged in Enterobacteriaceae causing infections in health care in the last decades of the Twentieth century, and they are now observed in isolates in different epidemiological settings both in human, animal and the environment. Likely originated from a chromosomal peni...
