Determination of Thermal Response on Mold Surface and Recommendation of Feasible Heating Time and Gas Flow Rate for a Circular Cavity by Gas Preheating
No full textImproving the performance of the trolley supply chain with a focus on visibility.
No full textThe lack of visibility, significant investment and a presumption of fleet shrinkage falter the decision-making process of a Dutch airline. Five decision areas have been identified and for each decision area improvements strategies or alternatives have been designed. Selecting the best alternative per decision area is a multi-criteria decision making problem. Therefore, a more sophisticated method is required to support the decision-maker. For this problem the novel Best-Worst Multi-Criteria Decision Making Method (BWM) has been selected. The BWM has been successfully applied to select the best alternative per decision area. Next steps for the airline are the implementation of the chosen alternatives.SEPAMTransport & LogisticsTechnology, Policy and Managemen

Environment-insensitive two-photon ratiometric probe for in cellulo quantitative measurement of hydrogen peroxide
No full textThe quantitative analysis of a biological analyte directly through fluorescence imaging is essential in biomedical sciences but remains as a challenge owing to the environment-sensitive nature of fluorescence intensity. We show that a fluorescent hydrogen peroxide probe based on an in cellulo super-bright benzothiazolyl-benzocoumarin dye of which emission properties are insensitive to environmental changes offers a reliable and practical means for the quantitative analysis of hydrogen peroxide in cells and tissues directly through ratiometric imaging both under one-photon and two-photon excitation conditions. Different cellular hydrogen peroxide concentrations were determined for several cell lines and also for tumour and normal tissues. © 2021 The Author(s)11Nscopu

Numerical investigation of free-stream rudder characteristics using a multi-block finite volume method
No full textThe turbulent flow around ship rudders in uniform inflow is computed by solving the Reynolds-averaged Navier-Stokes equations. The standard k-#epsilon# turbulence model with wall function is applied. The conservation equations are discretized by a (nearly) second-order finite volume method in a block-structured body-fitted grid and solved by the SIMPLE method. A simple procedure is applied to determine the cell-face velocity independent of the under-relaxation factor used in solving the momentum equations. The two-dimensional flow around various profiles is computed for a range of attack angles. Up to the stall angle the computed lift agrees well with measurements, whereas drag, stall angle and lift beyond the stall angle are a little over-predicted. The rudder profile HSVA MP73-xx proved to be superior to the most-used NACA 00xx profile. The three-dimensional flow around rudders of different aspect ratio, taper ratio, profile shape and thickness was computed at different Reynolds numbers. Also here, in general the results agreed very well with measurements below the stall angle whereas greater differences were observed beyond stall. The HSVA MP73-xx profile was again found superior to the standard NACA 00xx profile with respect to lift slope, maximum lift and drag as a function of lift.
