In this paper, by using C-sequentially sign property for bifunctions, we provide sufficient conditions that ensure the existence of solutions of some vector equilibrium problems in Hausdorff topological vector spaces which ordered by a cone. The conditions which we consider are not imposed on the whole domain of the operators involved, but just on a locally segment-dense subset of the domain.

       In this paper an SIS epidemic model with saturated incidence rate and treatment func- tion is proposed and studied. The existence of all feasible equilibrium points is discussed. The local stability conditions of the disease free equilibrium point and endemic equilibrium point are established with the help of basic reproduction number.However the global stabili- ty conditions of these eq...

abstract downy mildew of cucurbits is one of the most important diseases of cucumber in humid areas and greenhouses. damage of disease is estimated 50% to 100% in suitable climatic conditions. therefore, achieving resistant or tolerant genotypes can be designed as the most important and safe method to reduce the damage and increase the benefits of cucumber farming. in order to evaluate the resi...

This paper studies whether (and how) corporate decisions are affected by internal factors (such as the financial conditions of own company) and external actions local competitors) in an imperfectly competitive environment. We study listed real estate developers Beijing a case study. Our hand-collected dataset includes transaction-level information booked indicators profitability, liability, liq...

This paper studies a fractional boundary value problem of nonlinear differential equations of arbitrary orders. New existence and uniqueness results are established using Banach contraction principle. Other existence results are obtained using Schaefer and Krasnoselskii fixed point theorems. In order to clarify our results, some illustrative examples are also presented.

The development of start-ups is a driving force the local and regional economy. Therefore, it should be in interest municipal authorities to take actions for their organizational resource support. In conditions limited public resources, however, difficult multifaceted task. this article, authors attempt determine influence on establishment start-ups. As natural environment type entrepreneurship...

In this paper, two inverse problems of Stephen kind with local (Dirichlet) boundary conditions are investigated. In the first problem only a part of boundary is unknown and in the second problem, the whole of boundary is unknown. For the both of problems, at first, analytic expressions for unknown boundary are presented, then by using these analytic expressions for unknown boundaries and bounda...

In the present work, forced convection heat transfer of slip flow in porous micro-tubes with local thermal non-equilibrium between the gas and the solid matrix is investigated numerically. For this purpose, the flow is considered hydrodynamically developed but thermally developing. The Darcy-Brinkman-Forchheimer model in conjunction with separate energy equations for the gas and the solid matri...
