Dragbrotschning av invändiga profiler

High-precision cutting in metal is very complicated, a lot of parameters affect the result: what geometries to be manufactured, surface roughness and tolerances to be achieved, batch size etcetera. When pull-broaching internal parts this might be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary toolwear it is essential to use the right cuttingfluid and the right cuttingspeed for an example.

Från ansökarland till medlemsstat. -En studie av Polens förhandlingsprestation under EU-utvidgningsförhandlingarna

In May 2004 the European Union enlarged from 15 to 25 member states and it was the biggest enlargement since the foundation. Two years earlier Poland, as one of the new member states, finished four years of accession negotiations with the EU.This study focus on the case of Poland and how the accession negotiations with EU were conducted. According to the theoretical framework of asymmetric negotiations Poland was said to be a weak party and the EU was considered a strong party in the enlargement negotiations.The aim of the thesis is to examine Poland's negotiation performance and determine what Polish failure and success in the accession negotiations depends on. The research contains a illustration of the motives for enlargement, the negotiation process and structure, attitudes and behaviour and finally results of negotiations in specific areas.The study concludes that Poland's negotiation performance was influenced by the Polish negotiation team's unpleasant attitude, confused organizational structure, lack of coalition partners and the strong will to become a member state, in both positive and negative ways. Finally, Poland was most successful in negotiations that concerned specific issues which were of great importance for Poland but less prioritized by the EU..

Utveckling och applicering av en aviditets-ELISA för bovint respiratoriskt syncytialt virus :

Bovine Respiratory Syncytial Virus (BRSV) is a common cause of respiratory disease among young cattle. The virus causes severe losses; the herd mortality rate can sometimes be as high as 20 %. In this study the avidity (i.e the antigen binding force) of BRSV specific antibodies was measured to see if there was a difference between antibodies produced during an acute phase of infection and antibodies produced by earlier infected animals. A commercially available ELISA-testkit against BRSV-specific antibodies was used and an incubation step with 6M urea was added. The effect of the urea is that it breaks the weak bonds between antibodies and antigen while the stronger bonds remain intact. Four different groups of animals were included in this study; seven calves that were naturally infected, three acutely infected calves with known time of infection, five cows that were seropositive during several years and four experimentally infected calves that had been a part of a vaccine trial. The results of this study showed that antibodies produced during the acute phase of an infection had a low avidity and that the avidity increased with time after infection.

Forza TV? : debatten kring den medierade valkampanjen i det italienska parlamentsvalet 1994

During the 1994 Italian elections many things were new for the voters. A new election system, new parties emerging where old traditional ones were dying out because of long ongoing corruption scandals that were coming up to the surface. In all this one man, Silvio Berlusconi, a famous Italian businessman, stepped in and with his two allied parties Lega Nord and Alleanza Nazionale he swept away the nation in a never before seen election campaign. Many things have been said about the motifs and the way he prosecuted the election campaign for the Forza Italia. But what I try to see for this thesis is the awereness in the Italian print media from this particular period - how and if the debate about an in just electoral campaign existed in the country from the date Silvio Berlusconi entered ?the playing field? as he called it and up to the days of election..

Nationalistiska och främlingsfientliga? -En diskursanalys av högerpopulistiska partier i Skandinavien

The focus of this study is the ways in which the discourses of the three largest right-wing populist parties in Scandinavia ? Danish Dansk Folkeparti, Norwegian Fremskrittspartiet and Swedish Sverigedemokraterna ? are articulated and on defining which individuals they include and exclude. The discourses of the three parties are compared and analyzed to determine whether they constitute specific nationalist and culturally racist discourses. The problem is addressed by applying a social constructivist theory of nationalism and cultural racism, and specifically the binary opposition ?we? and ?them?, on a material consisting of the respective parties? member magazines from 2007.

Revisionsutskott i svenska aktiebolag: En statistisk analys

The recent development in several countries? legislation and best practice recommendations in relation to corporate governance in general and audit committees in particular have affected Swedish listed corporations in the form of the Swedish Corporate Governance Code and the coming EU-directive. This paper aims to discover what factors affected Swedish listed companies to form audit committees when this was entirely voluntary. We collected data from the annual reports of 121 Swedish listed companies and formed eleven hypotheses as to what factors we believed affected the voluntary formation of audit committees based on Agency Theory, economies of scale and circumstances specific to the Swedish environment. We then analyzed the data through the use of a multivariate logistic regression model.

Man är som en hamburgare: man har stora krav både uppe- och nerifrån. : En kvalitativ studie om mellanchefers upplevelser av sin roll som mellanchef i olika former av människobehandlande organisationer i offentlig sektor.

The aim of this study was to explore and gain understanding of the situation between managers in different forms of human service organizations. I chose to use a qualitative method and conducted semi-structured interviews with five professional middle managers in the public sector. To accomplish my purpose, I worked on the basis of several questions. The questions dealt with the role of middle management and what it involves, how it is perceived and what the middle managers think of the specific requirements for them and their leadership in organizations that provide services relating to people.  As a result of the analysis I have used the theory of social roles that describes the meaning of the different roles and role conflicts that arise in connection with various and conflicting expectations. The review of the results shows that middle managers in human service organizations experience to have to deal with a complex leadership role.
