objectives: specific language impaired children, despite being normal in cognitive and neurological characteristics, and also normal levels of hearing, experience multiple problems in syntax comprehension. this study compared the passive comprehension as one of syntactic structures in persian-speaking typically developing children and specific language impaired children. methods: 10 children wi...
introduction: the passive sentence structure is one of the most interesting syntactic structures on language development. studies in some languages have indicated that comprehension of this syntactic structure takes place late in the language acquisition process. therefore, the purpose of this study is to investigate the comprehension of active and passive structures in 48-59- and 60-71-month-o...
We report on our investigation of a low Reynolds number non-equilibrium electrokinetic flow in a micro/nanochannel platform. Non-equilibrium electrokinetic phenomena include so-called concentration polarization in a moderate electric field and vortex formation in a high electric field. We conducted a spectral analysis of non-equilibrium electrokinetic vortices at a micro/nanochannel interface. ...
In this paper, we present a novel, simple and low-cost micromixer that is based on the manipulation of self-assembled structures by an alternating magnetic field of magnetic microbeads over the section of a microfluidic channel. The principle is demonstrated using a microfluidic chip of polymethylmetacrylate (PMMA) that contains a 200 pm wide Y-shaped microchannel and is integrated with soft fe...
Currently, we are heading towards the period of nanotechnology which extends to many engineering disciplines. The necessity of its development is crucial to make life more convenient, to improve efficiency of each research field, and to integrate portable healthcare system. Thus, the next most important step is to develop a technology to meet the needs of both industry and research area [1]. He...
Based on the incompressible Navier Stokes equation (N-S) and coupling principle of laminar flow electric field, a new 3D electroosmotic micromixer with variable module is designed in this paper. A microchannel throughout to improve mixing efficiency. The efficiency different directions, positions, alternating voltages times was studied. It can be seen from simulation results that under influenc...
Euthanasia is one of the controversial topics in current medical ethics. Among the six well-known types of euthanasia, passive voluntary euthanasia (PVE) seems to be more plausible in comparison with other types, from the moral point of view. According to the Kantian framework, ethical features come from 'reason'. Maxims are formulated as categorical imperative which has three different version...
