CFD simulering av en fyrtakts Otto motorcykel motor

This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.

Orsak till sjuksköterskans stress och hur den påverkar omvårdnadsarbetet : En litteraturöversikt

Nurses in health care have a responsible and sometimes stressful job. Nowadays there?s a high pace in health care where many decisions have to be made during time pressure, a lot of information has to be transferred between health care units and sometimes complicated equipment are used. Cases of mistakes are reported more than ever to the national committee responsible for health care. Many of the mistakes, where the nurses are involved are due to the nurses? stress.The aim of this study was to gather information to describe causes of stress in nursing care and the nurses? experience of stress influence on health care.The method that was chosen for this study was a literature review where scientific, critically reviewed articles were analyzed.  The analysis resulted in two main themes.

Korruption och intressekonflikter : Hur hanteras offentliga intressekonflikter av den svenska lagstiftningen?

   Officially, Sweden has a very low level of corruption and in 2008 topped Transparency International?s list in terms of the perception of a lack of corruption. However, on closer examination it would appear that the Swedish public sector is not as clean as the Transparency International list suggests. What appears to be relatively common and quite widely accepted in Sweden, especially in local government, are conflict of interest situations in which public officials use their position to obtain advantages for themselves, their friends and their colleagues, in particular with respect to public procurement. According to the Swedish constitution, the public administration shall be governed by the principles on legality and objectivity. Grave violations of these principles are deemed illegal and contrary to the penal code provisions relating to bribery, public misconduct and breach of confidentiality.

Skillnader i kungsörnens (Aquila chrysaetos) flyttningsmönster beroende på ålder och klimatfaktorer : En studie för skyddet av kungsörn

This study examines the factors that influence the seasonal movements of Golden Eagles (Aquila chrysaetos), and can thus provide important information that helps to improve the protection of the species. There were two main purposes of this study. First, I wanted to analyze the difference between preferences of juvenile and adult Golden Eagles in their choice of southern or northern hibernation areas. Do younger eagles prefer moving longer distance to southern areas of Sweden? Second, I wanted to investigate how the climate influenced the choice of date of migration in the fall.

?DET ÄR JU MYCKET HUR MAN SKA VARA FÖR ATT PASSA IN SOM TONÅRING, OCH DÅ SPELAR JU NORMERNA I MEDIA ROLL FÖR HUR MAN TYCKER OM SIG SJÄLV? -En studie om Tv´s påverkan för ungdomars identitetsskapande

In this thesis we have examined if some young people's identity is influenced by television programs. We chose to illustrate this from a gender perspective and have made use of social construction theory. We did group interviews with 13 youngsters, in three groups, to find out how much insight they had in what they watch, if they believe that they are affected and how they believe that gender roles in television programs often look. Our questions are: Does young people's identity take influence of the TV program? How? Creates a social construction of gender in the television programs that young people are watching? Is there awareness among young people on what they watch and how is this in this case out? Important to emphasize is that our results are not necessarily representative of youngsters in general when we only had the opportunity to interview a few.

This was done in the context of how organisations of civil society have gained influence. Following questions were answered: How does UNICEF Sweden legitimise its operation? Which strategies does UNICEF Sweden use to encourage involvement and donations?The study shows how UNICEF Sweden legitimises its work by promoting a unique influence, their unique methods of work and by showing how the organisation helps the most disadvantaged children.

Utvärdering av lokal styrelse i Veberöd - En deliberativ demokratisk utvärdering

This thesis evaluates the user board of the elememtary school in Veberöd, Sweden. In this process an evaluation model is developed. The model itself gets evaluated in a meta-evaluation to improve the model for future use.The starting point of the evaluation is the deliberative democracy theory. Although Sweden is a representative democracy an official desire exists to have a democracy with deliberative qualities. The evaluation model is constructed to fit this context and is therefore, not only, set out from classical goal-based evaluation but also from deliberative democratic evaluation.

Intuition i beslutsfattande : En studie om det intuitiva beslutsfattandet och dess påverkande faktorer vid Akademiska sjukhuset i Uppsala

Managers operating within the dynamic society of today are said to rely on intuition when effective and quick decisions are to be made. This skill or phenomenon has aroused an interest within the academic world of management whom has explored intuition, its relation to decision making and its influencing factors, especially in the private sector. Intuitive decision making is however not isolated solely to this sector but also involved in decision making associated to the public sector. Therefore, the aim of the thesis is to investigate whether managers at the hospital Akademiska in Uppsala involve intuition in decision making and to what extent the factors time, amount of information, individual experience and decision complexity influence the intuition.The theoretical framework includes academic research regarding how intuition and rationality affect decisions, the concept of intuition and factors influencing the intuitiveness of decision making. Furthermore the theoretical discussion explores intuition connected to leadership, negative aspects of intuitive decisions and a comparison between different factors that separates public and private sector in terms of decision making.

Bottenfaunan i Stensjöån och dess tillflöde Bokån : - en undersökning av tre lokaler

The purpose of this study has been to examine whether the bottom fauna of the stream Stensjöån, has been negatively influenced since the harvesting of peat began on the nearby peat moss Skäftesmyr or not. Comparison has been made with the results of index calculations from earlier examinations in the stream, two calculated indexes has been made, Danish fauna index and ASPT-index. The sampling was made with the kick sampling method, SS-EN 27 828. Three locations were chosen for the examination, one upstream from the peat moss, one just downstream from where the brook from the peat moss joins Stensjöån and a third location near the outlet of the stream to the lake Stensjön. The samples were sorted and the found animals identified to the taxonomic level required for the calculation of the two indexes.
