Public and private sector collaboration to establish digital business ecosystems
This paper explores the extent in which public and private sector collaboration to set up a digital business ecosystem shapes the way digital entrepreneurs frame their roles. The study focuses on the case study of digital entrepreneurship in Bahrain, and particularly on the interactions that take place between public sector [...]
A secure framework for mobile cloud computing
Mobile Cloud Computing (MCC) has only been a natural evolution that has emerged post the amalgamation between cloud computing, the advancements in wireless technologies, and mobile technologies dominating the scene as of late. MCC offers many promises. It has the potential to override the mobile device limitations, empowering the user [...]

The effect of the choice of financing on small and medium enterprises’ post-entry performance-case of bahrain
This study investigates the effects of the choice of financing on Small and Medium Enterprises (SMEs) in the context of Bahrain. SMEs play a major role in the private sector especially in emerging markets. However, information asymmetries between lenders and entrepreneurs raise the issue of the different financing implications on [...]
Structural and magnetic properties and DFT analysis of ZnO:(Al,Er) nanoparticles
The structural, optical and electrical properties of un-doped and (Al,Er) co-doped zinc oxide (ZnO) powders synthesized by hydrothermal method were investigated. The obtained samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), energy-dispersive spectroscopy and magnetic measurements. XRD results reveal that the incorporation of Al and Er in [...]
First principles study of dehydrogenation properties of alkali/alkali-earth metal doped Mg7TiH16
First principles calculations were performed to investigate the influence of vacancy and alkali/alkali earth metals (Li, Na, K and Ca) doping on the dehydrogenation properties of Mg7TiH16. The occupation energy of dopants and dehydrogenation energy of defected Mg7TiH16 were calculated. It was found that dopants prefer to substitute for Mg [...]
Optical, magnetic and structural properties of ZnFe2O4 nanoparticles synthesized by conventional and microwave assisted combustion method: A comparative investigation
In the present work, zinc ferrite nanostructured materials were synthesized by a microwave combustion method (MCM) using Okra (Abelmoschus esculentus) as a plant extract and compared with the ones synthesized by a conventional combustion method (CCM). Plant extracts play a dual role of both oxidizing and reducing nature. Microwave assisted [...]
Linkage between company scores and stock returns
Previous studies on company scores conducted at firm-level, generally concluded that there exists a positive relation between company scores and stock returns. Motivated by these studies, this study examines the relationship between company scores (Corporate Governance Score, Economic Score, Environmental Score, and Social Score) and stock returns, both at portfolio-level [...]
Nanostructured Oxide Materials for Photodegradation of Dyes
Water purification has become a worldwide problem, in particular in industrialized countries, where wastewater usually contains organic pollutants, such as dyes from the textile industry, leather tanning industry, paper production, food technology, agricultural and pharmaceutical industries. The development of an effective treatment for these effluents is the subject of considerable [...]
Entropy generation in rayleigh-bénard problem for different geometrical cavities
Entropy generation for the natural convection phenomena is studied for different geometrical cavities that have identical boundary conditions and unit area. The key characteristic parameter in this study was the Grashof number. The effect of Grashof number on Nusselt number and entropy generation has been studied using finite element method. [...]
