Hägglunds Drives in Mellansel, Sweden, manufacture radial piston hydraulic motors foremostwithin applications in the industry. These motors have several sliding contacts, one of these, isthe contact between piston ring and cylinder bore. The radial piston hydraulic motors advantageis to produce high torque in very low rotation velocity, this result in that the maximum slidingvelocity between piston ring and cylinder bore, during the whole stroke, is very low. Theconsequence of this low sliding velocity is that the contact between piston ring and cylinderbore, during the whole stroke, is bound to the boundary lubrication regime. This result in, thatthe piston ring is exposed to wear, thus affect the service life of the complete hydraulic motor.To minimize wear of piston ring, it is essential to determine the oil film thickness between thepiston ring and cylinder bore.

Resultaten av vår undersökning visar på att vi generellt sett inte kan säga om individuella investerare agerar enligt regret theory eller inte. En del resultat tyder dock på att vissa effekter inom teorin är applicerbar på individuella investerare. Vi kan urskilja trender som tyder på att individen beter sig på ett visst sett och resonerat kring varför han beter sig så. Individen föredrar alltid det säkra alternativet om förluster eller stora vinster står på spel. Om skillnaden i säkerhet är väldigt liten försummar han den.

After the 9/11 attack the United States declared war against terrorism, which launched a conflict between indefinable transnational networks and states. In this war it became clear that the strategies used in traditional wars between states were not sufficient. New strategies have been discussed, but without any concrete results.In this thesis assassinations of terrorist leaders ordered by states is being presented as a possible strategy in the war against terrorism. Assassinations have been used in all times to shift political power but is today not morally accepted. This thesis aims to show that when used under the premisses of the just war theory, the strategy can be equally morally justified as any traditional war.

Frågeställningen var; Kan det undersökta företagets återkommande kommunikationsproblem förklaras, utifrån Heifetz? (1994) teori, med att medarbetarna har identifierat och hanterat dem felaktigt? Data samlades in genom kvalitativa intervjuer på en svensk arbetsplats och analyserades enligt en induktiv tematisk analys.

This bachelor thesis aims to analyse archaeological finds related to mead during the Late Iron Age in southern Scandinavia. Five central places from the Iron Age are compared to five historical texts, that in some way connects to either the central places or to the use of mead. This will be done by using action theory. The action theory focuses on what kind of actions humans have done to create social and cultural purposes. Since the last part of the Late Iron Age, the Viking Age, is getting more popular due to movies, games and tv-shows it is also relevant to study how modern-day mead represents the Viking Age through its marketing.

Klassisk kriminologisk forskning fokuserar på antingen individbaserade eller miljörelaterade förklaringar till brottsliga handlingar. Situational Action Theory avser att föra samman dessa två synsätt för att bilda en integrerad kriminologisk handlingsteori. Vad får Situational Action Theory för stöd i den kriminologiska forskningen? Vad finns för kritik? Och vad bör forskningen fokusera ytterligare på när det kommer till att testa teorin? Den forskning som finns tillgänglig och som jag presenterar i denna litteraturgenomgång visar att teorin får stöd i empirisk forskning. De flesta studier visar att teorin får bra stöd, några visar stöd för vissa delar av teorin medan andra delar av teorin inte får något stöd.

The aim of this study was to examine, in the work against bullying how collaboration between the school counselor and other professions is described by the different professions within the student health team as well as how they describe that the different competencies involved in such teams shapes problem definitions and solutions. The student health (swedish- elevhälsoteamet) team of which the study is based on consists of different professions such as school counselors, school nurses, special education teachers, school psychologists and school principles. We have interviewed representatives of all the above mentioned professions with the exception of school psychologists using a qualitative research design. In this study we have chosen to focus on two student health teams from two different primary schools located in a middle-sized municipality in southern Sweden. We have analysed the results using new institutional theory and the terms domain and power. The main conclusion of the study is that school counselors themselves feel they have a specific knowledge regarding bullying but have difficulties in capitalizing on it while collaborating with the other professions in the student health team.
