background: yazd waste stabilization pond facilities consist of three stabilization pond systems, module 1, module 2 and module 3 that awsp module 1 has started its operation. the existing facilities have had several problems in their operation. the objectives of this research were to evaluate the performance of stabilization ponds in wastewater treatment of the city of yazd, due to several pro...

the class of ads modules with the sip (briefly‎, ‎$sa$-modules) is studied‎. ‎various conditions for a module to be $sa$-module are given‎. ‎it is proved that for a quasi-continuous module $m$‎, ‎$m$ is a uc-module if and only if $m$ is an $sa$-module‎. ‎also‎, ‎it is proved that the direct sum of two $sa$-modules as $r$-modules is an $sa$-module when $r$ is the sum of the annihilators of these...

This special issue amply fulfils its aim of moving the study of gene × environment (GE) interplay forward constructively and creatively, exploiting contributions from diverse disciplines. Rather than discussing the many interesting findings and methods in this special issue, I will comment on two cross-cutting issues - one about genes and the other about the environment - that came to mind as I...

An accurate formula exists for describing the decay of the current following the imposition of extreme concentration polarization on a disk electrode under diffusion-controlled conditions. It has been amply validated by diverse simulations and is presented here in a more compact form than hitherto. The formula finds application beyond the realm of potential-step chronoamperometry.

This paper analyses security mechanism and authentication, key agreement protocol of 3G system amply, puts forward a amelioration scheme. This scheme assures security communications without credible VLR. This paper analyses ameliorative protocol and resolves the security communications problem between MS and HLR.

let r be a commutative ring and m be an r-module. we say that m is fully primary, if every proper submodule of m is primary. in this paper, we state some characterizations of fully primary modules. we also give some characterizations of rings over which every module is fully primary, and of those rings over which there exists a faithful fully primary module. furthermore, we will introduce some ...
