In the last years, there were two fields that experienced an astonishing growth within biocatalysis community: photobiocatalysis and applications of flow technology to catalytic processes. Therefore, it is not a surprise combination these research areas also gave place several recent interesting articles. However, best our knowledge, no review article covering advances was published so far. Wit...

BACKGROUND The aim of this study was to investigate the effects of different delivery circuit configurations, nebulizer positions, CPAP levels, and gas flow on the amount of aerosol bronchodilator delivered during simulated spontaneous breathing in an in vitro model. METHODS A pneumatic lung simulator was connected to 5 different circuits for aerosol delivery, 2 delivering CPAP through a high...

As identified in the CFD Vision 2030 Study commissioned by NASA, validation of advanced RANS models and scale-resolving methods for computing turbulent flow fields must be supported by continuous improvements in fundamental, high-fidelity experiments designed specifically for CFD implementation. In accordance with this effort, the underpinnings of a new test platform referred to herein as the N...

OBJECTIVES/HYPOTHESIS Paradoxical vocal fold motion and exercise-induced paradoxical vocal fold motion (EIPVFM) are two related conditions that do not have definitive diagnostic criteria. Much of the EIPVFM literature describes patients with characteristic physiologic findings of severe upper airway obstruction or obvious airflow limitation in the clinical context of exertional dyspnea with aud...

tip leakage loss introduces major part of losses of the rotor in axial gas turbines. therefore, the rotor blade tip has a considerable effect on rotor efficiency. to understand the flow physics of the rotor tip leakage, we solve the flow field for different tip platforms (passive flow control) and by considering coolant tip injection (active flow control). various blade tip configurations such ...

Label-free optical biosensors are powerful tools in drug discovery for the characterization of biomolecular interactions. In this study, we describe the use of four routinely used biosensor platforms in our laboratory to evaluate the binding affinity and kinetics of ten high-affinity monoclonal antibodies (mAbs) against human proprotein convertase subtilisin kexin type 9 (PCSK9). While both Bia...

In this work, we demonstrate for the first time the combination of conventional pressure-driven microfluidics with electrically-programmable digital microfluidics. The use of continuous microfluidics in channels of fixed geometry is widespread and has been used for numerous applications. Digital microfluidics is an emerging area based on programmable electrowetting droplet movement. Merging the...

Integration hell is a prime example of software evolution gone out of control. The Sisyphus continuous integration system is designed to prevent this situation in the context of component-based software configuration management. We show how incremental and backtracking techniques are applied to strike a balance between maximal feedback and being up-to-the-minute, and how these techniques enable...

in order to present a new and high performance structure of pem fuel cell and study the influence of the flow direction and distribution on the rate of reactants diffusion, three novel models of vertical reactant flow injection into the anode and cathode reaction area field have been introduced. they consist of one inlet and two inlets and also a continuous channel. the governing equations on t...

to simulate a new economical architecture for pem fuel cell and investigate the effectiveness of the introduced structure on the performance, computational fluid dynamics (cfd) code is used to solve the equations for a single domain of the cell namely: the flow field, the mass conservation, the energy conservation, the species transport, and the electric/ionic fields under the assumptions of st...
