    The main goal of the safe power outlet project is to make power outlets smart and integrate it to all old and new electrical wiring of homes and offices to eliminate the costs. Using the designed socket, home and office electrical appliances can be smarten and controlled remotely through wireless technology. The device designed in this project, is a smart power outlet that supports Wi-Fi connection and the user can connect directly to it and control it by the specific mobile application. There is no need for any other interfaces such as a modem or router, and the user can connect directly to the device. This is the innovative part of the project making it different from the conventional power outlets on the market. All home and office appliances running on AC power can be connected to a safe outlet directly and without an interface; they can be controlled via wireless network by mobiles. This device smartens all old and conventional outlets without making any changes in wiring. It also enables the control via Wi-Fi on the outlets

    Weblog effects on social capital

    Weblog is the newest and clearly one of the most influential computer mediated communication (CMC) tools. Growing body of literature about the weblog effects on education, marketing, journalism, and human resource management is a sign of importance and significant effects of weblogs. This rapidly growing communication tool is expected to have significant impact on the work life of the individual and organization. However, there is little research evidence as to the nature and extent of this impact. Using a sample of 326, this research examines the effects of weblogs on social capital and its components: social connections, trust, and reciprocity. Implications of these findings for research and practice are discussed

    A novel bioactive PEEK/HA composite with controlled 3D interconnected HA network

    Polyetheretherketone (PEEK) is a high-performance thermoplastic biomaterial which is currently used in a variety of biomedical orthopaedic applications. It has comparable tensile and compressive strength to cortical bone with favourable biocompatibility. However, natural grade PEEK-OPTIMA has shown insufficient bioactivity and limited bone integration. Bioactive PEEK composites (e.g., PEEK/calcium phosphates or Bioglass) and porous PEEK have been used to improve bone-implant interface of PEEK-based devices, but the bioactive phase distribution or porosity control is poor. In this paper, a novel method is developed to fabricate a bioactive PEEK/hydroxyapatite (PEEK/HA) composite with a unique configuration in which the HA (bioactive phase) distribution is computer-controlled within a PEEK matrix. This novel process results in complete interconnectivity of the HA network within a composite material, representing a superior advantage over alternative forms of product. The technique combines extrusion freeforming, a type of additive manufacturing (AM), and compression moulding. Compression moulding parameters, including pressure, temperature, dwelling time, and loading method together with HA microstructure were optimized by experimentation for successful biocomposite production. PEEK/HA composites with a range of HA were produced using static pressure loading to minimise air entrapment within PEEK matrix. In addition, the technique can also be employed to produce porous PEEK structures with controlled pore size and distribution
