Karlstad University is a state university in Karlstad, Sweden. The university, being a former university college was granted university status in 1999 by the Government of Sweden. Originally it was a branch of the University of Gothenburg. There are about 50 training programmes, 20 programme extensions and 800 courses within humanities, social studies, science, technology, teaching, health care and arts. As of today, it has approximately 12,500 students and 1,200 employees. Its university press is named Karlstad University Press.Service Research Center , or "CTF", at Karlstad University is one of the world's leading research centers focusing on service management and value creation through service.On March 26, 2009 the faculty of Economics, communication and IT formed Karlstad Business School as a brand of their educational programmes in the business related areas.Karlstad University has two a cappella groups, Sällskapet CMB and Söt Likör. Many students live at the nearby student accommodation facilities called Unionen and Campus Futurum.The motto of the University is Sapere aude . Wikipedia.

With the rapid accumulation and processing of personal data by numerous organizations, it is of paramount importance to protect people from adverse uses of their data, while allowing them to enjoy the benefits the use of these data can possibly provide. This is the question of protecting citizens privacy, while enabling them to make informed decisions regarding their actions with privacy implications. The PRIVACY.US innovative training network will train thirteen creative, entrepreneurial and innovative early stage researchers (ESRs) to be able to reason, design and develop innovative solutions to questions related to the protection of citizens privacy, considering the multidisciplinary and intersectoral aspects of the issue. ESRs will be trained to face both current and future challenges in the area of privacy and usability. PRIVACY.US offers a combination of research-related and transferable competence skills that will enhance the career perspectives of the ESRs in both the academic and non-academic sectors. The consortium consists of five universities and five non-academic organizations. This deliberate and balanced construction will ensure that the project outcomes and impacts are maximal with respect to the call criteria and the EU policy areas regarding data security and privacy. The market potential for the generated knowledge is also a key element of this proposal. The consortium industrial partners are three SMEs, one large enterprise, and a data-protection authority. The ESRs will receive comprehensive training and engage in intersectoral collaboration. Through this collaborative effort, the project will make a significant contribution and impact to the ESRs future careers. It will also contribute to shaping future privacy policies and practices in Europe and will significantly advance the state of the art in privacy and usability research.

In this paper we investigate the global dynamics for the minimally coupled scalar field representation of the modified Chaplygin gas in the context of flat Friedmann-Lemaître-Robertson Walker cosmology. The tool for doing this is a new set of bounded variables that lead to a regular dynamical system. It is shown that the exact modified Chaplygin gas perfect fluid solution appears as a straight line in the associated phase plane. It is also shown that no other solutions stay close to this solution during their entire temporal evolution, but that there exists an open subset of solutions that stay arbitrarily close during an intermediate time interval, and into the future in the case when the scalar field potential exhibits a global minimum. © 2013 American Physical Society.

The objective was to test the application of a novel, non-destructive photo-method estimating the larval encystment of one of the highly threatened unionid mussels, the freshwater pearl mussel (Margaritifera margaritifera) on the gills of its host fish, brown trout (Salmo trutta). There were significant correlations between the encystment intensity based on microscope counts and using the new photo-method for both young-of-the-year and older brown trout just after the encystment in October 2007 and just before larval release from the host fish in June 2008. The mean encystment intensity based on the two methods did not differ from each other for the two age classes of trout when based on comparisons including all individuals. An aquaria experiment showed that there were no differences in survival or growth between fish subjected to the treatments: photo-method and individual marking, photo-method and a control. When applied to encystment in single streams, there were significant correlations between the mean encystment intensity in each stream based on the methods for both trout age classes. Therefore, it may be possible to get reliable estimation of the encystment rates without injuring the mussel or the host fish, which may also be used in restoration and cultivation work. Furthermore, the larvae of M. margaritifera are among the smallest of all the worldwide-distributed, threatened unionid mussel species. The photo-method may therefore also be used for other mussel species with larger larvae, as they are more easily recognized on photos. Therefore, it may now be possible to investigate every life stage of unionid species without using harmful methods at all. © 2011 Elsevier Ltd.

Residues from forest-industry wastewater-treatment systems are treated as waste at many pulp and paper mills. These organic substances have previously been shown to have potential for production of large quantities of biogas. There is concern, however, that the process would require expensive equipment because of the slow degradation of these substances. Pure non-fibrous sludge from forest industry showed lower specific methane production during mesophilic digestion for 19. days, 53. ±. 26. Nml/g of volatile solids as compared to municipal sewage sludge, 84. ±. 24. Nml/g of volatile solids. This paper explores the possibility of using anaerobic co-digestion with municipal sewage sludge to enhance the potential of methane production from secondary sludge from a pulp and paper mill. It was seen in a batch anaerobic-digestion operation of 19. days that the specific methane production remained largely the same for municipal sewage sludge when up to 50% of the volatile solids were replaced with forest-industry secondary sludge. It was also shown that the solid residue from anaerobic digestion of the forest-industry sludge should be of suitable quality to use for improving soil quality on lands that are not used for food production. © 2012 Elsevier Ltd.

In sheet metal forming, different types of tool steels are used depending on sheet quality. In the present work, influence of amount, and type, of primary carbides and carbo-nitrides was investigated regarding tool galling resistance against austenitic stainless steel. A significant impact of amount of carbides on galling resistance was observed and tool performance was improved as volume fraction increased. However, no influence of carbide type was distinguished. Alloying by nitrogen further improved the galling resistance and best tool performance was observed for a tool steel comprising only carbo-nitride M(C,N) particles. Besides transfer of sheet material, several other tool damage mechanisms were observed such as cracking, micro-chipping and abrasive scratching. © 2012 Elsevier Ltd.
