in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...

Introduction: The values of individuals that orient their preferences and behaviors are not the same; this can lead to disagreements and be the basis of value conflicts. The present study aimed to analyze the value conflict resolution experiences and how to deal with the value conflicts among the faculty members. Methods: In this qualitative study, a semi-structured interview was carried out w...

asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...

Traces of waters footsteps can rarely be found in history of Kashan. Traces which Sohrab Sepehri, a contemporary figure of Kashan, showed us and its meaning runs deep in our mythology. In this article, we believe that tracing water’s footsteps gives us a better source and description on the social history of this city. Based on the recent documents about Kashan, this essay finds an important cl...
