Analysis of non-laminar flows in coarse alluvial beds has a wide range of applications in various civil engineering, oil and gas, and geology problems. Darcy equation is not valid to analyze transient and turbulent flows, so non-linear equations should be applied. Non-linear equations are classified into power and binomial equations. Binomial equation is more accurate in a wide range of velocit...

This research focused on studying the flows of a null Cartan curve specified by velocity and acceleration fields. We have proven that tangential normal velocities are influenced binormal along motion. The fields used to drive time evolution equations for frame torsion curve. objective this work is construct family inextensible curves from initial surface formed obtained numerically visualized. ...

This study focuses on the carrying capacity estimation for Darkesh forest in Northeast Iran. Four factors were used for estimating the carrying capacity including tourist flows, size of the area, optimum space available for each tourist, and visiting time. Results showed that the physical carrying capacity was 2727 ha or 165 visitors/day, while the real carrying capacity was 2719 ha or 132 visi...

Concerns regarding the Trans-Pacific Partnership (TPP) have raised awareness about the negative public health impacts of trade and investment agreements. In the past decade, we have learned much about the implications of trade agreements for public health: reduced equity in access to health services; increased flows of unhealthy commodities; limits on access to medicines; and constrained policy...

‎in this paper, we discuss about existence of solution forintegro-differential system and then we solve it  by using the petrov-galerkin method. in the petrov-galerkin method choosing the trial and test space is important, so  we use alpert multi-wavelet as basisfunctions for these spaces. orthonormality is one of theproperties of alpert multi-wavelet which helps us to reducecomputations in the...
