Backgrounds and Objectives: Improvement of water quality standards and inability of mono layer filters in producing such quality caused researchers attended to multi layer filters. Due to specific characteristics of anthracite and leca can improve removal of organic materials and Surface over flow rate. The aim of this research was evaluation performance of dual media filters (anthracite/leca) ...
We give a theoretical lower bound for the slope of a Siegel modular cusp form that is as least as good as Eichler’s lower bound. In degrees n = 5, 6 and 7 we show that our new bound is strictly better. In the process we find the forms of smallest dyadic trace on the perfect core for ranks n 8. In degrees n = 5, 6 and 7 we settle the value of the generalized Hermite constant γ′ n introduced by B...
In the context of the ring Q[x,y], of polynomials in 2n variables x = x1, . . . , xn and y = y1, . . . , yn, we introduce the notion of diagonally quasisymmetric polynomials. These, also called diagonal Temperley-Lieb invariants, make possible the further introduction of the space of diagonal Temperley-Lieb harmonics and diagonal Temperley-Lieb coinvariant space. We present new results and conj...
apart from other aspects, desert is a natural environment and is one of the appealing terrestrial elements. putting its symbolic and fictional senses aside, the term “desert” bears mystic sense more than material sense. in addition to the worlds materialistic experiences, desert has attracted the attention of writers because it creates a kind of inner experience, which returns the individual in...
Nowadays, expensive living, elevated expectations, and changes in gender roles have changed families' lifestyles to dual-career couples. Examining the challenges of this issue can affect the mental health of the community. The current research aimed to compare dual-career and single-career couples in dimensions of the coping strategies and the differentiation. The statistical population of the ...
در دهه اخیر، ساختار فراماده الکترومغناطیسی توجه زیادی را در فیزیک و جوامع مهندسی به خود جلب کرده است. فراماده ساختاری است الکترومغناطیسی با خصوصیات همگن ومصنوعی که دارای خواص غیر عادی می¬باشد. این ساختارضریب گذردهی الکتریکی منفی و ضریب نفوذپذیری مغناطیسی منفی دارد و تحت عنوان ساختار چپگرد شناخته می¬شود. ابعاد سلولی آنها از طول موج کوچکتر است. این ساختار در طبیعت یافت نمی شوند. انتشار امواج در ا...
we introduce the notions of t-dual rickart and strongly t-dual rickart modules. we provide several characterizations and investigate properties of each of these concepts. it is shown that every free (resp. finitely generated free) $r$-module is t-dual rickart if and only if $overline{z}^2(r)$ is a direct summand of $r$ and end$(overline{z}^2(r))$ is a semisimple (resp. regular) ring. it is sho...
In this paper, we consider convex quadratic semidefinite optimization problems and provide a primal-dual Interior Point Method (IPM) based on a new kernel function with a trigonometric barrier term. Iteration complexity of the algorithm is analyzed using some easy to check and mild conditions. Although our proposed kernel function is neither a Self-Regular (SR) fun...
