Two modal decomposition techniques, including proper orthogonal (POD) and dynamic mode (DMD), were used to identify the wake patterns past single two crossing cylinders in 60° 90° arrangements with gap ratio G = 4. The flow was simulated using direct numerical simulations (DNS) for Reynolds numbers Re 100. From analysis, flow’s spatial scale decreased increasing frequency. main modes identified...

Abstract A three-dimensional incompressible annular jet is simulated by the large eddy simulation (LES) method at a Reynolds number Re = 8 500. The time-averaged velocity field shows an asymmetric wake behind central bluff-body although flow geometry symmetric. proper orthogonal decomposition (POD) analysis of fluctuation vectors conducted to study dynamics flow. distribution turbulent kinetic ...

Thrombotic microangiopathy is a form of antibody-mediated rejection (ABMR): it is the main complication of ABO-incompatible (ABOi) kidney transplantation (KT). Herein, we report on two cases of ABMR with biological and histological features of thrombotic microangiopathy (TMA) that were treated by eculizumab after ABOi KT. The first patient presented with features of TMA at postoperative day (PO...

1392 December 2012 We read with interest the recent article by Flink et al.1 in which the authors evaluated the frequency of postoperative delirium (POD) in 106 elderly patients aged 65 yr or older after elective knee replacement. The screening for POD was thorough and well-conducted with recognized screening tools, with an incidence of 25% on days 2–3 postoperatively. The pathophysiologic mech...

PROOF [1] is an extension of ROOT [2] enabling interactive analysis of large sets of files in parallel on clusters of computers. Normally users get PROOF provided by administrators as a pre-installed shared cluster. To avoid certain disadvantages of “static” PROOF clusters PoD [3] has been developed. PROOF on Demand is a tool-set, which dynamically sets up a PROOF cluster at user request, on an...

Zhang X., Shao X. (2015): Characterisation of polyphenol oxidase and peroxidase and the role in browning of loquat fruit. Czech J. Food Sci., 33: 109–117. Polyphenol oxidase (PPO) and peroxidase (POD) were extracted from a new loquat fruit cultivar (Ninghaibai) and characterised using reliable spectrophotometric methods. In both cases, the optimum pH for PPO was 4.5 and 5 for POD, and their opt...

The effect of dried pods of Caesalpinia spinosa, known as tara, on pH, cooking loss, lipid oxidation, colour stability and texture of model meat systems stored at 4 °C for 21 days was investigated. Tara pod powder showing a potential antioxidant activity was added at 0.02, 0.04 and 0.08% (by mass) directly to the pork batter and compared with a synthetic antioxidant, butylated hydroxyanisole (B...

Postoperative delirium (POD), which occurs in hospital up to 1‑week post‑procedure or until discharge, is a common complication, especially older adult patients. However, the pathogenesis of POD remains unclear. Although damage blood‑brain barrier (BBB) integrity involved neuropathogenesis POD, specific role BBB requires further elucidation. Anaesthesia using 2% isoflurane for 4 h results upreg...

Two peroxidases (EC. 1.11.1.7), POD I and POD II were purified from the roots of cultivatedRaphanus sativus L. Var. Cicil by one step ion-exchange chromatography after fractionation by acetone. The molecular weight of these enzymes were 43000 and 41000 Daltons and RZ 1.2 and 2.0 for POD I and POD II, respectively. Both enzymes consisted of a single polypeptide chain on SDS-PAGE. The maximum...
