Abstract

With their excellent high temperature mechanical, chemical and thermal properties, fibre reinforced ceramic matrix composites have emerged as an important class of materials having a wide range of applications in various technological fields. Microwave Enhanced Chemical Vapour Infiltration (MECVI) has been recognized as a new process route because of its ability to conserve the reliability and durability of the precursor materials. The primary advantage of using microwaves is that they cause an inverse temperature profile to be formed that prevents entrapment of accessible porosity and greatly accelerates the process. However, to develop the MECVI process further, a complete understanding of the effects of the process parameters on the infiltration mechanism and processing time is necessary. Modelling efforts can offer an insight into the critical factors in this process and suggest ways to optimize processing. A 2-D mathematical model investigating the densification of SiCf/SiC composites by microwave enhanced Chemical Vapour Infiltration (CVI) under forced-flow of the gaseous reactants is presented.

Abstract

Land use planning can now be considered as one of the best practices within natural Disaster Risk Management to improve the resilience of communities, ensure the safety of people and increase sustainability. Yet traditional land use planning and management practices lack the systematic nature to deal with risks associated with hazards, exposure and vulnerability. Risk based land use planning provides planners and managers the opportunity to move beyond planning for the likelihood of a natural hazard and to plan for the consequences of an event. The aim of this study was to review the tools and techniques that are used in risk based land use planning and eventually select a suitable one for the present case study, Mauritius. Google scholar was used as portal and keywords such as “risk based land use planning” were entered to extract relevant publications for the period 2010 to 2020. Over 90 papers were reviewed and 15 tools and techniques were identified as being in use in risk based land use planning. Consequently, an innovative 7-steps participatory/GIS based approach for risk reduction in the Mauritian context was proposed which considers communities’ participation in mapping land uses and disasters and translating the information onto GIS maps for visualization.

Abstract

ACL; The construction industry is searching for a more ecological material which can provide a good sustainability and also have the eco-friendly label. The quest to protect the environment has enabled researches to find alternate materials which can fit the concrete matrix to produce a concrete that can meet the demand of the construction industry. The purpose of this research is to substitute traditional materials with construction and demolition waste by keeping the same slump value and by replacing natural fine aggregates (NFA) with Construction and Demolition Waste (C&D) materials and investigate their properties on fresh and hardened concrete. To determine and compare the properties, different tests were performed to evaluate the workability, density, compressive strength, flexural strength and absorption of each concrete mix. The results demonstrated that, construction and demolition waste materials with a define slump range decreases the compressive strength and flexural strength, and the water absorption increases with increasing C&D content.

32. Towards emerging green information and communication technologies: a review

Author

Bekaroo, Girish and Bokhoree, Chandradeo

Abstract

Though the ICT industry has been one of the fastest growing industries in many countries over the past years, its relationship with the natural environment has not been given much consideration. This growing industry has as main negative impact on the environment, climate change in the form of global warming, caused by the emissions of carbon in the air. In order to minimize the harms caused by the growing IT industry on the environment, Green ICT is an emerging solution which is increasingly being adopted by businesses and computer users. Green ICT refers to environmentally sustainable computing and is a discipline that studies, develops and promotes environmentally friendly and resource-efficient ICT products over their entire life cycle. This paper discusses the effects of the growing IT industry on the environment along with a review of emerging green information and communications technologies and best practices which will shape the future of computing at home and in businesses.

Abstract

The need for a suitable and efficient solid waste collection and transportation system is essential in order to minimise environmental impacts. Collection vehicles consume significant amount of diesel, engendering high CO2 emissions as well as elevated costs. This paper focuses on the evaluation of possible causes for the rising CO2 emissions for curbside waste collection vehicles, through the causal analysis of 6 different collection areas in Mauritius. As disclosed by the survey carried out in this research, a collection vehicle in Mauritius is likely to emit about 7 metric tons of CO2 per annum. Hence, determining the factors influencing such a high level of emission is fundamental. The causal analysis is an effective means to identify and understand the relationships and impacts of various parameters affecting emissions for these types of vehicle. [ABSTRACT FROM AUTHOR]

Abstract

Though the IT industry has been one of the fastest growing industries in many countries over the past years, its relationship with the natural environment has not been given much consideration. This growing industry has as main negative impact on the environment, climate change in the form of global warming, caused by the emissions of carbon in the air. Green IT relates Information Technology and the environment by promoting studies, development of techniques for improving energy efficiency and reducing waste in the full life cycle of computing in the IT. This paper discusses the effects of the growing IT industry on the environment along with a review of existing work in Green IT. A conceptual framework for energy consumption and reduction using system dynamics modelling is also proposed which links the different locations within an IT organisation where most of the energy consumption takes place and a case-study is given that illustrates the application of the conceptual framework in a small in-house software development company consisting of ten employees.
