A three-dimensional computational fluid dynamics model of a proton exchange membrane fuel cell (PEMFC) with both gas distribution flow channels and Membrane Electrode Assembly (MEA) is developed. A set of conservation equation is numerically solved by developing a CFD code based on the finite volume technique and SIMPLE algorithm. In this research, some parameters like oxygen consumption, water...
Cell structures were introduced by W. Debski and E. Tymchatyn as a way to study some classes of topological spaces their continuous functions through discrete approximations. In this work we weaken the notion cell structure prove that, resulting class space admitting such generalized includes non-regular spaces.
In the current project on effects of heavy ion irradiation in planar multilayer cell cultures, a “multicellular sensitization” was observed, i. e., multilayers were more radiosensitive than monolayers when treated under identical conditions [1]. This phenomenon was observed in multilayers, but also in multicell spheroids of SiHa and WiDr human tumor cells using plateau region or Bragg peak carb...
The multi-scale nature of architectured materials raises the need for advanced experimental methods suitable identification their effective properties, especially when size is finite and they undergo extreme deformations. present work demonstrates that state-of-the art image processing combined with numerical analytical models provide a comprehensive quantitative description these solids global...
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...
The classical approach to extreme value modelling for multivariate data is to assume that the joint distribution belongs to a multivariate domain of attraction. In particular, this requires that each marginal distribution be individually attracted to a univariate extreme value distribution. The domain of attraction condition may be phrased conveniently in terms of regular variation of the joint...
In recent years, abuse of synthetic cathinones, in particular, mephedrone, has increased among young adults worldwide. The study aim is to investigate the effects of mephedrone exposure during the gestational period on mice offspring outcomes, focusing on hippocampal neurotoxicity. The pregnant mice received mephedrone (50mg/kg, sc) on a regular schedule (once daily on all days, from day 5 to 1...
