The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.

The IPv6 protocol offers with some new functions, one of them is auto configuration. With auto configuration it is possible for nodes, i.e. hosts and routers, for automatically associated with IPv6 addresses without manual configuration. Auto configuration it is another protocol as it uses Neighbor Discovery protocol (ND) messages (ND is mandatory in the IPv6 stack). The main purpose of ND is that nodes can discover other nodes on the local link, perform address resolution, check that addresses are unique, and check the reachability with active nodes.There are exactly the same vulnerabilities of IPv6 as IPv4 and is now exception, ND if not properly secured.

Today it is mandatory for every college or university student to pay a union fee to their student?s union. The fee is mandatory and is a payment for writing examinations, receiving grades. The fees purpose is also intended to secure the education quality and student influence. In the presence of the abolishment of the union fee the Swedish student?s unions stand before an uprising competition between themselves and most likely a decrease in membership.

Denna uppsats använder branschvis sysselsättningsförändring i Sveriges 21 län mellan åren1995-2002 som ett mått på regional tillväxt. Alla branscher i ett län delas in enligt SNIsystemetsbranschklassificering. För varje bransch beräknas enligt Economic-base modellenen lokaliseringskoefficient som visar branschens sysselsättningsandel i länet i förhållande tilldess sysselsättningsandel i riket. Den bransch som i respektive län uppvisar högst värde påkoefficienten benämns basindustri. Sambandet mellan sysselsättningsförändringen i varje länsbasindustri och länets totala sysselsättningsförändring undersöks genom en paneldatastudie.Förutom basindustrins sysselsättningsförändring används den länsvisa befolkningsnivån somförklarande variabel.

The terror attack in New York year 2001 was a turning point in international politics. New policies were reformed in both USA and EU to secure their citizens from terrorism.

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

The dissertation deals with an account of actual problem, which can arise within EMC and power quality. The cause of power interruption and what can be done to minimise the power interruption is discussed. It also includes a definition of planning levels and which factors one needs to have control over to carry out a possible planning strategy and how the local distributions net could be more secure. The electrical net could be secure but no system can be free from interruption.The dissertation examines two distribution transformers: GLA40T1 (Glansås) and T399 in Tranås Energy which don?t have regulators.

In Sweden there are 299 000 working in the construction industry. The construction industry is one of the industries where most accidents occur every year. During the last ten years there have been 111 death accidents in the construction industry and 48 of them were falling accidents. That means, in average, one death accident every month.Falling accidents gives serious injuries to the persons who are affected by them. It is anticipated that this report will investigate the factors beyond the falling accidents and also to present proposals that can decrease the number of falling accidents in the future.To secure a healthy and safe construction site it is of great importance that both the employers and the employees cooperate towards the same goal.

AbstractThis essay consists of an analytical study of three present-day Swedish films depiction of teenage life. From these films we like to see how youths are described, what attributes they are given, in shape of attire and different symbolic items, such as language and body expressions. The essay emphasizes which values that dominates among the illustrated teenage groups and compares it to the values and expectations that we can derive from an adult society. Here we let the school?s main determining base documents, Lpo 94 and Lpf 94, represent the dominating values of the society.Our hypothesis is that media, and also these films, creates images that affects the societies comprehension of teenagers and also how teens see themselves.

In an attempt to prevent ground damage and to reduce harvesting costs, StoraEnso's districts Värmbodal and Fryken, selected a number of final felling areas where the base roads have been marked by planners in the districts. The parties involved in the experiment are mainly planners, harvester operators and forwarder operators. The purpose of this paper is to determine the findings of this trial and to find cost savings or lost revenue. This has been done with a sample of interviews from the involved parties who logged the chosen felling areas. Literature about the interview process has been used to facilitate data collection, interpretation and analysis of the material. If we look at profitability based on assumed income and expenditure, revenue per MWh would be 63 SEK.

The authors were curious and asked themselves if teachers are aware of the base of their teaching in various teaching situations. Are teachers at all capable of expressing that in words? One of the reasons that the authors chose the particular issue was because they think teachers have the task to satisfy the needs of all students and therefore they found it interesting to study how various teachers act. The purpose of the study is to observe teachers didactical awareness, and how it can be added to their intentions and actions, as in how they speak about their teaching and how they act in various teaching situations. Methods used in the study were observations and qualitative interviews.
