let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...

Fibre-reinforced concrete (FRC) has been increasingly used in construction for several decades to reduce crack growth by incorporating one or two types of fibre reinforced elements under the static load. This paper intends investigate experimentally how hybrid systems (micro and macro polypropylene fibres steel fibres) can enhance performance RC beams subjected loading restricting development m...

Algae-based wastewater treatment is a promising technology with various applications for excess biomass such as biofertilizer production or valuable elements extraction. The benefits of the have been discussed larger plants (WWTPs), but use microalgae in decentralized has barely reported. current study screens possible resource recovery potential onsite technology, which adds algae-based post-t...

the present paper investigates how far ideologies can be tease out in discourse by examining the employed schemata by two ideologically opposed news media, the bbc and press tv, to report syria crisis during a period of nine months in 2011. by assuming that news is not a valuefree construction of facts and drawing on micro structural approach of schema theory, for the first time in discours...

cAMP regulates integrin-dependent adhesions of vascular endothelial cells (VECs) to extracellular matrix proteins, their vascular endothelial cadherin-dependent intercellular adhesions, and their proliferation and migration in response to growth and chemotactic factors. Previously, we reported that cAMP-elevating agents differentially inhibited migration of human VECs isolated from large vascul...

How abortion is dealt with in law and policy is shaped through the multiple political and societal discourses on the issue within a particular society. Debate on abortion is constantly in flux, with progressive and regressive movements witnessed globally. This paper examines the translation of human rights norms into discourses on abortion in Northern Ireland, a region where abortion is highly ...

Granular anisotropy is attributable to many complex behaviors of granular materials and reflects important microstructures at the grain scale, and should be fully considered towards the development of realistic constitutive models for such materials. In this paper, we present a study on the behavior of anisotropy using a three-dimensional Discrete Element Method (DEM). Isotropic packings of san...
