Most people agree that the total ecological impact of society has become more than this planet can endure. This is because we consume our resources (such as oil and water) faster than they can regenerate and because we release more substances into the environment than can be assimilated (e.g. CO2). In other words: our society is not sustainable on a long term basis. Biocatalysis is being promoted
This paper reviews work on self-tuning regulators. The regulator algorithms, their theory and industrial applications are reviewed. The paper is expository—the major ideas are covered but detailed analysis is given elsewhere.
Belysningens tekniska utveckling och användning och förändringen när de industriella belysningsteknikerna införs
Glyoxal (CHOCHO), as an indicator of photochemical “hot spots”, was for the first time the subject of a differential absorption lidar (DIAL) campaign. The strongest absorption line of glyoxal in the blue wavelength region – 455.1 nm – was chosen as the experimental absorption wavelength. In order to handle the effects of absorption cross-section variation of the interfering gas – nitrogen dioxide
Abstract. The source material consists of interviews with twenty Scandinavian children aged seven and eight. The interviews focus on two issues: first, the way in which the children describe their participation at home in decisions about food and meals; and second, children's housework. The qualitative data has been supplemented with various quantitative studies: we consider the children’s attitud
