The region of sea ice near the edge of the sea ice pack is known as the marginal ice zone (MIZ), and its dynamics are complicated by ocean wave interaction with the ice cover, strong gradients in the atmosphere and ocean and variations in sea ice rheology. This paper focuses on the role of sea ice rheology in determining the dynamics of the MIZ. Here, sea ice is treated as a granular material w...
T-cell growth factor, more recently termed interleukin 2 (IL-2), is the product of activated T lymphocytes and is considered the principal trophic factor for T lymphocytes. The activity of IL-2 preparations is assessed by the degree to which they support the growth of various IL-2-dependent cell lines. We report that murine epidermal epithelial cells (keratinocytes) produce and release a factor...
چکیده : نظریه ی شیوه ی تولید آسیایی ، اولین بار توسط مارکس و سپس در تأیید نظریات او ، در آثار انگلس مطرح شد . این نظریه علاوه بر شیوه تولید ، به بحث درباره ی ماهیت دولت در جوامع آسیایی می پردازد . در این پژوهش ، وجه تولید آسیایی و نظریات پیرامون آن در توسعه نیافتگی ایران ، مورد بحث و بررسی قرار می گیرند . مهمترین نظ the asian production theory was first introduced by marx and then was suppo...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
Several theoretical predictions of the mass flow rate of granular media discharged from a silo are based on the spontaneous development of a free-fall arch region, the existence of which is still controversial. In this Letter, we study experimentally and numerically the particle flow through an orifice placed at the bottom of 2D and 3D silos. The implementation of a coarse-grained technique all...

We develop a continuum description of partially fluidized granular flows. Our theory is based on the hydrodynamic equation for the flow coupled with the order parameter equation, which describes the transition between flowing and static components of the granular system. This theory captures important phenomenology recently observed in experiments with granular flows on rough inclined planes [A...
We study a dilute granular gas immersed in thermal bath made of smaller particles with masses not much than the ones this work. Granular are assumed to have inelastic and hard interactions, losing energy collisions as accounted by constant coefficient normal restitution. The interaction is modeled nonlinear drag force plus white-noise stochastic force. kinetic theory for system described an Ens...
