Retaining Emphasis on "Systems Approach" when Assessing E-Commerce by Life Cycle Assessment

In the issue of using Life cycle assessment (LCA) for assessing E-commerce, we had some epistemological observations, via content analyse method, indicating that LCA has not only aspects of the ‘Systems Approach’ but also of the ‘Analytical Approach’, with even less emphasis on the former in practical terms. The purpose of this paper is to shed light on the connection among these observations, and

Treatment of Textile Wastewater by Combining Biological Processes and Advanced Oxidation

Popular Abstract in English Colors have always been part of human life and culture. Today natural pigments have been substituted by synthetic dyes that usually end up threatening nature itself by polluting the environment. To what extent can we use chemistry and biology to minimize the environmental impact of the textile industry? During the dyeing process a certain amount of dye, 2 to 50 percent,Treatment of textile wastewater is challenging because the water contains toxic compounds that have low biodegradability. Dyes, detergents, surfactants, biocides and more are used to improve the textile process and to make the clothes resistant to physical, chemical and biological agents. New technologies have been developed in the last decades and in particular Advanced Oxidation Processes (AOPs)

Negationens syntax i älvdalskan

Th article deals with the system of negation in Övdalian (Swe. älvdalska), focusing on two inter-clausal negations and negative concord in the language.

Lattice Boltzmann Method for Water-Splitting over Nanorrods with Emphasis on Reactive Mass Transport in 3D

Lattice Boltzmann method (LBM) is an alternative to conventional CFD to capture the detailed activities of the transport processes at microscale. Here LBM is used to model the hydrogen production by splitting water by incident sunlight over water covered Si-nanorods. The purpose of this study is, by a 3D microscale model, to investigate the transport and the formation of the hydrogen bubbles by el
