1. EXISTENCE OF SOLUTIONS FOR n-GENERALIZED MIXED VECTOR EQUILIBRIUM PROBLEMS IN BANACH SPACES
by Zi-yan Li, Zhong-quan He & Da-peng Gao
Abstract

In this paper, some generalized mixed vector equilibrium problems in Banach spaces are introduced and the equivalence of two classes of h-generalized mixed vector equilibrium problems is proved under suitable assumptions. By using the equivalence theorem, some results on the existence of solutions for h-generalized mixed vector equilibrium problems are obtained.

2. LINEAR 3-ARMENDARIZ RINGS

by Ayoub Elshokry & Eltiyeb Ali

Abstract

In the present note we study the properties of linear 3-Armendariz rings, which are generalization of 3-Armendariz rings and linear Armendariz rings and the connections among linear 3-Armendariz rings, 3-Armendariz rings and ring satisfies condition (P). We prove that a right Ore ring R  is linear 3-Armendariz if and only if so is  Q, where Q  is the classical right quotient ring of  With the help of this result we can show that a commutative ring  R is linear 3-Armendariz if and only if the total quotient ring of R  is linear 3-Armendariz.

3. LINEAR MODELS OF DIFFERENT SCALES
by Xian He, Xudong Zhu, Hao Zhang & Qianlai Zhuang
Abstract

In tMany statistical models for environmental studies can be run at different scales, e.g., for daily, weekly or monthly data. It is important to know how these models differ in terms of prediction. We provide some theoretical results to compare these models. We show that when there is no high order terms of explanatory variables, the small scale model yields more efficient estimators for model parameters and also produces better prediction. However, when there are high order terms of explanatory variables, a larger scale model can be run in two different ways: product-of-sum or sum-of-product. Current practice made it hard to compare directly the larger scale model with the small scale model and no explicit conclusions are drawn in general. We provide a case study on gross primary production of terrestrial ecosystems in the conterminous United States to demonstrate our results.

4. APPROXIMATING COMMON ELEMENTS OF THE SET OF AMENABLE SEMIGROUP AND VARIATIONAL INEQUALITY AND INFINITE FAMILY OF NON-EXPANSIVE MAPPINGS AND GENERALIZED MIXED EQUILIBRIUM PROBLEMS
by Qiang Li & Jun Li
Abstract

In this paper, we introduce a new iterative scheme for finding a common element of the set of fixed point of an infinite family of non-expansive mappings and left amenable semigroup, the set of solution of generalized mixed equilibrium problem and the set of solutions of the variational inequalities for solving inverse strongly monotone mappings in Hilbert spaces by using a hybrid steepest descent methods. Then strong convergence of the scheme to a common element of the three sets is proved. Our results improve and generalize some well-known results in the literature.

5. THE ACCUMULATION OF SOME TOXIC METALS IN FOOD PLANTS NEAR A POLLUTED SITE
by Kebir Tahar, Bouhadjera Keltoum & Baba Ahmed Abderrazzak
Abstract

The transfer of heavy metals from the former sites of mining activity to the nearby agricultural soils is a serious environmental risk and concern due to the potential health impacts of consuming contaminated produce. The present study is determinate to the level of nine heavy metals: Fe, Pb, Zn, Ni, Cu, Cd, Mn, Cr and As in the different agricultural soils and three plants alimentary: Pepper (Capsicum annuum), Artichoke (Cynara cardunculus variety scolymus) and Grape (Vitis vinifera) grown near of dumpsite of site industrial activity AlZINC in Ghazaouet city western of Algeria country. Soil sample were takes from land in different direction, since the metal are generally associated with the fine fraction, the investigation was carries under 2 mm fraction sample according to NF ISO 11464 and the plants are ashes. The extraction of all metals was using by digestion with aqua regia method (nitric-chloric acid ratio1:3) and analysis via AES-ICP. The plant samples from the immediate environment were highly contaminated with Zn, Cd and Mn. particularly, grape met some of the conditions to be classifies as accumulators for Pb, Zn, Cu, Cd, Ni and Cr consequently and she revealed a health risk for human and livestock due to the spread of the metal pollution from dumpsites to agricultural areas.

6. NEW ALGORITHM FOR SOLVING THE MODIFIED KORTEWEG-DE VRIES (mKdV) EQUATION
by K.R. Raslan & H.A. Baghdady
Abstract

In this paper we will investigate the finite element approach using collocation method with septic spline interpolation functions to solve the Modified Korteweg-de Vries (MKdV) equation. It is unconditionally stable by von Neumann method. The exact soliton solution and the conserved quantities are used to assess the accuracy and to show the robustness of the scheme. The interaction of two solitary waves for different parameters is discussed.

7. LONG RUN IMPACT OF GOVERNMENT EXPENDITURE AND TAX ON LIQUIDITY AND EMPLOYMENT IN IRAN ECONOMY
by Ayoub Faramarzi, Mohammad Sadegh Avazalipour, Farnaz Khaleghi & Nader Hakimipour
Abstract

This paper studies the impact of fiscal policy on money supply in Iran’s economy .The trend of the main variables in this paper during the covered period are presented and analyzed. In order to study the main factors of on employment of labor and, Vector Auto regressive model (VAR) and Vector Error Connection (VECM) as well as co-integration test of Johansen Co-integration Test during 1976-2009 is used to find out the relation and also to evaluate the model.                                                                                

 Results showed that the effect of government expenditure on the both of the employment and liquidity is positive but the effect of tax on the employment is negative. The coefficients of the tax and government expenditure on liquidity are 0.44 and 0.07.

The coefficients of the tax and government expenditure on employment are -0.17 and 0.15.

8. MAXIMUM LIKELIHOOD FOR GENERALIZED LINEAR MODEL AND GENERALIZED ESTIMATING EQUATIONS
by A. Lanani
Abstract

The most frequent methods to analyze statistical data are the regression methods, whereby the maximum likelihood method or that of least squares. On the one hand, in the context of the longitudinal data or repeated measurements, these data are often unbalanced; on the other hand, their law of probability are not normal rending the passage to other models with other methods of estimate possible. In this paper, we initially recalled the maximum likelihood method applied to a mixed linear model; thereafter, we introduced the generalized estimating equations and their method of resolution. Finally, we showed the relationship between the maximum likelihood method and the iteratively reweighted least squares ones.

10. APPLICATION OF THE BPOMS FOR NUMERICAL SOLUTION OF THE ISOTHERMAL GAS SPHERES EQUATIONS
by Behrooz Basirat & Mohammad Amin Shahdadi
Abstract

In this article we present a matrix method for solving isothermal gas spheres equations (IGSEs) with initial conditions by Bernstein polynomials operational matrices (BPOMs) on interval [a,b]. This method transforms (IGSEs) and the given conditions into matrix equation which corresponds to a system of linear algebraic equations.
