Biosynthesis of Zinc oxide Nanoparticles using Barringtonia acutangula Flower Extract and Evaluation of their Antibacterial and Antioxidant Activities

Zinc oxide (ZnO) has broad applications in various areas. Nanoparticle synthesis using plants is an alternative to conventional physical and chemical methods. It is known that the biological synthesis of nanoparticles is gaining importance due to its simplicity, eco-friendliness and extensive antimicrobial activity. Also, in this study we report the synthesis of ZnO nanoparticles (ZnONPs) using Barringtonia acutangula   flower extract. The prepared ZnO nanoparticles have been characterized by UV–Vis absorption spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM)). The antioxidant activity of the nanoparticles was tested by the α-diphenyl-β-picrylhydrazyl (DPPH) method. Antibacterial properties of the synthesized ZnONPs were evaluated against Staphylococcus aureus and Escherichia coli by disc diffusion method

Main differentiating issues in aligning information systems with business performance

The information systems and technologies (IS/IT) are a decisive platform in the response capacity of organizations to the new management imperatives through new solutions that permit to improve their competitive position. As information management is a highly differentiating area, the present study compares several enterprises of different sectors, located (headoffice or branch) in the Algarve region, with the aim of systematising the main differentiating issues related with adoption, restructuring and implementation of information systems and supportive technologies. Every organization should define an accurate and in time plan which, in case of adopting and implementing information systems, has to analyse results within the same plan and on a yearly basis of the system's activity always aligned with the business strategy. Given the potential of ERP and CRM as powerful tools to guide customer-oriented understanding, greater attention is required on their economic viability for sustainable business dynamics
