Green Computing-An Environmentally Sustainable Modus Operandi

Generating compatible and competitive materials that are environmentally sustainable and economically viable is paramount for the success of additive manufacturing using renewable materials. We report the successful application of renewable, modified lignin-containing photopolymer resins in a commercial stereolithography system. Resins were fabricated within operable ranges for viscosity and cure properties, using up to 15% modified lignin by weight with the potential for higher amounts. A four-fold increase in ductility in cured parts with higher lignin concentration is noted as compared to commercial SLA resins. Excellent print quality was seen in modified lignin resins, with good layer fusion, high surface definition, and visual clarity. These materials can be used to generate new products for additive manufacturing applications and help fill vacant material property spaces, where ductility, sustainability, and application costs are critical.

The increasing of energy cost and also environmental concern on green computing gaining more and more attention. Power and energy are a primary concern in the design and implementing green computing. Green is of the main step to make the computing world friendly with the environment. In this paper, an analysis on the comparison of green computer with other computing in E-learning environment had been done. The results show that green computing is friendly and less energy consuming. Therefore, this paper provide some suggestions in overcoming one of main challenging problems in environment problems which need to convert normally computing into green computing. In this paper also, we try to find out some specific area which consumes energy as compared to green computing in E –learning centre in Malaysia. The simulation results show that more than 30% of energy reduction by using green computing.

In the discussion on the future of the EU, the topic of differentiated integration has become a strategic issue, with different variants beginning to appear as modus operandi of the European Union, which has become a subject of controversy among Member States. Significantly, the debate on differentiated integration began to be accompanied by reflections on disintegration. This article attempts to define disintegration on the assumption that it should be defined through the prism of integration, and that such a defining process can not be limited to concluding a one-way contrast between disintegration versus integration and vice versa. This is due to the assumption that the European Union is a dichotomous construct in which integration and disintegration mutually exclude and complement each other. This dichotomy is most evident in the definition of integration and disintegration through the prism of Europeanisation top-down and bottom-up processes that generate, reveal, visualize, stimulate integration mechanisms what allows to diagnose their determinants.
