On the interpretation of pressure POD modes in the near field of a subsonic jet in terms of hydrodynamic and acoustic pressures
No full textIn this work an experimental investigation of the near-field pressure of a compressible jet is presented. The Proper Orthogonal Decomposition (POD) of the pressure fluctuations measured by a microphone array aligned with the jet spreading angle and placed in the linear hydrodynamic regime is performed in order to provide the streamwise evolution of the jet structure. The wavenumber-frequency spectrum of the space-time pressure fields re-constructed using each POD mode is computed in order to provide an interpretation of the physical nature of the mode in terms of hydrodynamic/acoustic pressures. Specifically, non-radiating hydrodynamic, radiating acoustic and ’hybrid’ hydro-acoustic modes are found based on the topology of the wavenumber-frequency spectrum and on account of the phase velocity associated with the spectral energy bumps. Furthermore, the preferential propagation direction in the far field of the radiating POD modes is detected through the cross-correlation with the measured far-field noise

Multicenter performance evaluation of the Unyvero IAI cartridge for detection of intra-abdominal infections
No full textIntra-abdominal infections (IAIs) are one of the most common type of infections in patients with sepsis and an important cause of death in intensive care units. Early detection and treatment are necessary to reduce patient complications and improve outcomes. The Unyvero IAI Application (Curetis GmbH) is the first automated assay to rapidly and simultaneously identify a large panel of bacteria, fungi, toxins, and antibiotic resistance markers directly from IAI-related samples. The assay was evaluated in four European clinical laboratories in comparison to routine microbiological practices. A total of 300 clinical samples were tested with an overall sensitivity of 89.3% and specificity of 99.5%, while time to results was reduced by an average of about 17 h compared to identification (ID) results and 41 h compared to full antibiotic susceptibility testing (AST) results. The Unyvero IAI was able to detect additional microorganisms compared with culture, in particular anaerobes, with most detections confirmed by sequencing. The most frequent resistance markers detected were mecA/mecC (n = 25), aacA4 (n = 20), and blaCTX-M(n = 17) and carbapenemase genes were identified in nine specimens. Further studies are now required to determine the clinical impact of this new rapid test which could play a role in the successful treatment of IAI

No full textLaminar Sinusoidal and Pulsatile Flows in a Curved Pipe
No full textTwo components of pulsatile flow (i.e. steady flow and sinusoidal flow) are studied separately by particle image
velocimetry (PIV).The topology of the secondary flow structures, axial vorticities and transverse strain rates in a pure
sinusoidal flow and also in a steady flow are compared to those in a pulsatile flow through a curved pipe. The
experimental setup provides different conditions for the flow entering a 90° circular curved pipe of diameter 0.04 m
and curvature radius 0.22m. Pulsatile flows were studied for two stationary Reynolds numbers, Rest=420 and
Rest=600. The frequency parameters =10.26 and =14.51 were chosen to study pure sinusoidal flow (=r0)0.5).
Pulsating conditions were obtained by combining steady and sinusoidal flow for (Rest=600, =10.26), (Rest=600,
=14.51) and (Rest=420, =14.51). The results of this study contribute to a better understanding of mixing in a
developing laminar flow through curved pipes (helical and twisted/chaotic mixers) in steady state flow, pure
sinusoidal flow and pulsatile flow
