In this paper, we explore the methodological and epistemological implications of conducting feminist projects in management information systems (MIS) research. These implications revolve around four core themes: that feminist research is situated in the margins, that current gender and MIS research is not adequately problematized, that feminist research questions the legitimacy and appropriaten...
Background: Although the presence of articular cartilage progenitor cells is already known, but due to lack of blood supply, its ability to heal is poor. In past, tissue engineering approaches has been mainly focused on the collection and culture of chondrocyte cells on biodegradable scaffolds such as polyglycolic acid in vitro and their autologous transplantation. Recently, due to the difficul...
Background and purpose: Natural bone is a combination of polymer and biological apatite, therefore, the composite scaffolds made of polymers and bioactive ceramics have found wide applications in bone tissue engineering studies. Among various polymers, the poly-L-lactic acid (PLLA) and hydroxyapatite (HA) have attracted much attention due to their optimal properties. In this study, using PLLA p...
Background: This study addressed the development of biodegradable and biocompatible scaffolds with enhanced biomechanical characteristics. The biocompatibility and the cationic nature of chitosan (CTS) make it more effective as a bone grafting material. Methods: The hydroxyapatite nanoparticles (nHA) were synthesized by hydrothermal method, and bioglass (nBG) (50% SiO2-45% CaO-5% P2O5) was synt...
Walkability is generally defined by the extent to which built environment supports and encourages walking promoting pedestrian comfort, connectivity convenience. This paper scrutinizes steps taken in Johannesburg develop walkability policies projects. It draws on empirical evidence from (e.g., Corridors of Freedom) projects Grayston Pedestrian Bridge) recently introduced. Rather than focusing m...
