With diversified requirements and varying manufacturing environments, the optimal production planning encountered in a steel mill has become more flexible and also complicated. The flexibility provides the operator with auxiliary options to satisfy customer requirements through an implementable integrated production planning. In this paper, a mixed-integer nonlinear programming (MINLP) model is fo

In this study, a group of Swedish social media users – politically active as well as “unpolitical” users – are interviewed in focus groups as well as individually about their attitudes towards online political participation, providing a deeper, more informed view of how social media participation works. Sweden, with its high levels of voluntary participation and with an avant-garde position in Int

Protein S is a cofactor of activated protein C; together they function as a regulator of blood coagulation. A human liver cDNA library constructed in bacteriophage lambda gt11 was screened with DNA fragments from a full-length bovine cDNA clone encoding protein S. Several cDNA clones were isolated and sequenced. The combined cDNA sequences encoded the mature protein and 15 residues of the leader s

In this paper we introduce the digitization challenge for higher education. Furthermore, three parallel ‘roads’ are proposed to consider in designing higher education content to address the digitization challenge. Program designers and educators will benefit by giving consideration to: (1) non-digital teaching activities that promote digital literacy, (2) digital opportunities to enhance tradition

This paper reports on the ENABLED 3DEditor and 3DViewer. The software design is described, and results from user tests with end users are reported. Both the Editor and Viewer are seen to work quite well. It is possible for a developer to quickly start working with the editor. The Viewer was well received by the users who are able to use it to understand an environment, get an overview and locate a

This contribution traces the international contacts and impact of the leader school for German doctors ('Führerschule der deutschen Arzteschaft') in Alt Rehse 1935-1943 through studies of a visitors' book and of biographies.We suggest that the 'Föhrerschule', an institution providing political and ideological education for health professionals, interested non-German physicians to a larger extent t

The evidence for the contribution of soil warming to changes in atmospheric CO2 concentrations and carbon stocks of temperate forest ecosystems is equivocal. Here, we use data from a beech/oak forest on concentrations and stable isotope ratios of dissolved organic carbon (DOC), phosphate buffer-extractable organic carbon, soil organic carbon (SOC), respiration and microbial gross assimilation of N
