A rare clinical case of native aortic valve infective endocarditis (IE) caused by Klebsiella pneumoniae in a 56-year old man without known risk factors predisposing to the development IE is presented. Diagnosis this patient was challenge due lack recent interventions that could be considered as source bacteremia, scarce manifestation and absence typical complications. Aortic vegetation detected...

the effect of mentha spicata l. extract on the corrosion behaviour of carbon steel in 1.0 m hcl solution was investigated using polarization, electrochemical impedance spectroscopy (eis) and electrochemical noise (en) techniques. the solution containing 250 ppm of the ethanolic solution of extract showed the highest inhibition efficiency (ie). the effect of temperature on the rate of corrosion ...

AproductADF1 : : : FN of invertible block-diagonalmatrices will be bandedwith a banded inverse. We establish this factorization with the numberN controlled by the bandwidthsw and not by the matrix size n:When A is an orthogonal matrix, or a permutation, or banded plus finite rank, the factors Fi have w D 1 and generate that corresponding group. In the case of infinite matrices, conjectures rema...

in this paper, the effect of penicillin g drug as a green corrosion inhibitor on mild steel in 1.0 mhydrochloric acid solution has been investigated using potentiodynamic polarization, electrochemicalimpedance spectroscopy (eis) and electrochemical noise (en) techniques. the inhibition efficiencywas found to increase with increasing inhibitor concentration. potentiodynamic polarizationmeasureme...

Abstract Background Infective endocarditis (IE) requires a high degree of suspicion and advanced level multidisciplinary management. In 2015, the European guidelines recommended formation an endocarditis-team (ET) for optimal treatment IE. 2011, we already established ET within hospital that was only consulted on demand certain patients. Since has been increasingly involved in management almost...
