    , Article Transportation Research Part D: Transport and Environment ; Volume 34 , January , 2015 , Pages 95-103 ; 13619209 (ISSN) Abbaspour, M ; Karimi, E ; Nassiri, P ; Monazzam, M. R ; Taghavi, L ; Sharif University of Technology
    Elsevier Ltd  2015
    Abstract
    Noise pollution in urban areas has many harmful effects on the citizens. There are varieties of noise generation sources of which the traffic noise could be a major source. The point which is perhaps less noticed is that sound level is not the only parameter to indicate the extent and intensity of noise pollution. Situation of urban land uses, distribution of population centers and types of passages can deeply affect the concern on this environmental issue but not with a similar ratio. This article presents an overlaying technique to define noise prone areas using all different factors involved. A case study was carried out in the District 14 of Tehran Metropolitan City where there are busy...

    , Article Research on Chemical Intermediates ; Volume 48, Issue 5 , 2022 , Pages 1793-1811 ; 09226168 (ISSN) Akhundi, A ; Naseri, A ; Abdollahi, N ; Samadi, M ; Moshfegh, A ; Sharif University of Technology
    Springer Science and Business Media B.V  2022
    Abstract
    Worldwide energy and environmental issues are forcing researchers to develop a green approach to produce a clean energy. However, traditional methods in reforming of fossil fuels to produce hydrogen (H2) are causing CO2 emission. Hydrogen is therefore an indirect greenhouse gas with a global warming potential. Hydrogen with high specific energy density can be considered as an efficient energy carrier as compared to fossil fuels. But hydrogen production from water splitting reaction has low efficiency, which limits its generation by green approach. For addressing this issue, different chemical hole scavengers have been applied, which is causing further environmental and economic problems. By...

    Elsevier B.V  2021
    Abstract
    The formation of liquid bridge is pertinent to many fields including seepage into underground fractured rocks as an environmental issue and capillary continuity between matrix blocks which controls oil recovery in fractured reservoirs. Evaporation from the surface of liquid bridge into the surrounding gas could affect the stability of liquid bridge and fracture capillary pressure, which is not well discussed in the available literatures. In this research, by the aid of analogy between the diffusive flux and electrostatic potential, a new model for predicting evaporation rate from a liquid bridge inside a horizontal fracture is presented. The proposed model is then coupled with Young-Laplace...
