The stable configurations, electronic structure and magnetic properties of B16N16, B8C24, Al and P inserted (BC3)8 was studied by performing density functional theory (DFT) calculations of the NMR parameters. The results indicate that B8C24 has semiconductivity property and be effectively modified by inserti...

Urban space has been formed in historical texture of cities under the influence of meaning and shape on the onehand and qualities related to human behaviors on the other hand. Among these points, neighborhood centers as themost important areas of social life in urban open space play a critical role in attracting people and improving qualityand vitality of environment. This study presents the re...

In this paper, we prove the existence and uniqueness of fixed points for cyclic (α,β)-admissible type F-contraction and F−weak contraction under the setting of modular spaces, where the modular is convex and satisfying the ∆2-condition. Later, we prove some periodic point results for self-mappings on a modular space. We also give some examples to s...

the urban open space is the context in which the human activities and behavior takes place and the socio-cultural relations of people happen in it. public spaces are places responding to the daily needs and public life in cities. these spaces throughout time and based on the socio-cultural and economic conditions would transform. urban spaces also are places for various activities. in a simple ...
