The One-Dimensional Turbulence (ODT) model is applied for the evaluation of internal pipe flows subject to electrohydrodynamic (EHD) forces. ODT formulation presented here incorporates effects electrostatic potential energy transfer kinetic flow due EHD instabilities in presence a corona discharge. Results integral quantities such as skin friction coefficient Cf and Nusselt number Nu are obtain...

To present a framework for compassionate teaching, the views of teachers and students on the topic were sought. These informants were chosen from among their corresponding populations in Tehran, using the snowball and mixed methods. Semi-structured interviews were used to gather the needed data. To analyze the data open coding and descriptive categorization were utilized. Results show that from...

In recent years, the availability and use of various antibiotics and antimicrobial agents have resulted in increase of drug resistant pathogens. Therefore, scientist’s attention has been diverted to find a suitable replacement for antimicrobial treatment. Graphene (G), as a two-dimensional (2D) carbon-based nanomaterials (CBNs) has a unique physicochemical properties including thermal, optical ...

abstract background: well-being is a subjective concept and means different things to various people. most of the research investigating the experience has concentrated on its problematic and pathological aspects. the aim of this research was to enhance the understanding of the contextual meaning of well-being based on personal life experiences of the participants. this will be of help to exper...

It is a part of everyday life that objects appear different from each perspective they are seen from. Ordinary language has plenty of expressions referring to abstract issues “from my point of view” or “your perspective”. In this article, we argue for a perspectivist approach to conceptual spaces, that is, an approach to concepts as entities whose definition depends on the perspective from whic...

In managerial and economic applications, there appear problems in which the goal is to simultaneously optimize several criteria functions (CFs). However, since the CFs are in conflict with each other in such cases, there is not a feasible point available at which all CFs could be optimized simultaneously. Thus, in such cases, a set of points, referred to as 'non-dominate' points (NDPs), will be...

In general the problem of interpreting the three-dimensional structure of an object from an X-ray image is a difficult one . This is due to the almost complete absence of depth cues in a typical radiograph containing as it does only shape and grey scale information. The spatial information usually encountered in two-dimensional images, for example photographs, is missing. Psychological depth cu...

We illustrated via the sunset diagram that dimensional regularization ’deforms’ the nonlocal contents of multi-loop diagrams with its equivalence to cutoff regularization scheme recovered only after sub-divergence were subtracted. Then we employed a differential equation approach for calculating loop diagrams to verify that dimensional regularization deformed the ’low energy’ contents before su...

Three-dimensional (3D) printing has been employed as a potentially useful aid for the guidance of complex surgical procedures in recent years. Many clinical practitioners have preliminarily investigated its effect on improving the patients’ outcomes. As one of developing country, China has put forward a series of national plans to advance the development of this relatively new field. In this pe...

Dimensionality reduction is an unsupervised task that allows high-dimensional data to be processed or visualised in lower-dimensional spaces. This tutorial reviews the basic principles of dimensionality reduction and discusses some of the approaches that were published over the past years from the perspective of their application to big data. The tutorial ends with a short review of papers abou...
