There are many elderly buildings, particularly those constructed during the million program, in need of renovations and plumbing replacement. An alternative to the traditional plumbing replacement is the relatively new and untested technique called relining. The purpose of the study is to thoroughly investigate the different types of relining that are currently available on the market to help enhance Peab?s knowledge before purchasing relining services. The theoretical part of this report is based on relevant information provided from companies, previous studies, investigations and reports within the area.

AbstractThis report discusses how the intranet as a communication tool can bedeveloped to become a daily work tool. An intranet can help the organization to get information out to the employees fast, and the employees can choose when they want to take part of the information. This report also discusses how the functions and the presented information can be developed to be even better. The proposals has been developed out from information gathered from a survey,the people who has answered the survey has been given their point of view of the intranet, and also proposals for improvements, which we have implemented in to our theory part. There is no company or organization that uses the exact same intranet solution.

This essay is a case-study of an ethnically homogeneous association, situated in an ethnically heterogeneous neighbourhood. The purpose is to examine the social capital of the members in this particular association. The theory of social capital claims that this form of association constitutes an example of bonding social capital, and is running the risk of becoming excluding towards non-group members. However, several scientists suggest that the ethnically homogeneous associations can assist immigrants in their new home countries to become a part of society, hence promote a more bridging form of social capital. This would be extra valuable in an ethnically heterogeneous context where the phenomenon of social capital often has a hard time.

Anorexia nervosa is a psychosomatic eating disorder that involves self starvation and fear of gaining weight. Our purpose was to study the methods of treatment available and the function of them. Another part of the purpose was to find out what kind of goals the treatment has and if an anorectic person can be cured. To understand the methods of treatment we also wanted to find out what the causes to the development of the disease can be. The questions were: 1.

This thesis compares the impact on disk performance in a GNU/Linux  environmentwith three encryption algorithms: AES,  Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that  is  drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..

This paper deals with breaks in upper secondary school. The aim with the study was to study the function of breaks for upper secondary students by investigating students? activities during breaks with the main issues: ?what does the students do during breaks??, ?how do they experience breaks?? and ?What is the relation between breaks and lessons??.A combination of the two complementary methods observation and interview was chosen to study this. The study was executed on an upper secondary school during one month. I have visited the school several times every week and written daily notes over my observations.

AbstractLean production has become one common concept within industries to make the work more effective and to meet today?s hard competition. A challenge for Chinese production is the threat from new low cost countries. It will become very difficult to succeed to produce to a lower cost than these countries; this led to that Chinese companies must develop new strategies, according to Lee and Zhou (2000). This will put China in front of new challenges and new strategies can be needed to retain their strong competitive advantages.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

The purpose of this study was to investigate if female and male reporters and interviewees get the same amount of time in the news feature in the Swedish news programs TV4-Nyheterna and SVT 1 Rapport. The aim of this study was also to investigate if there is a breakdown of the reporting lines between male and female reporters, that is, if they are reporting on various topics. In our study we also determined if the two television channels in any way are different when it comes to gender.Our main theory was that men are overrepresented both among reporters and interviewees and that they are dominant in both hard and soft news. We thought that SVT 1Rapport would have a better gender balance than TV4-Nyheterna because SVT 1 has been working on gender issues for a long time.We were using a quantitative content analysis to examine the 19:30 news on SVT 1 Rapport and 22:00 news on TV4-Nyheterna for two weeks in November 2010. We examined domestic and foreign news and determined how much time each sex got.

To take part in a summer hockey camp during the summer vacation is something that is very popular. This study is carried out through parents of ice-hockey active children in the south of Sweden. The main purpose of this study is to investigate for which reasons parents might let their children participate in a summer hockey camp. It is also studied which parts of the contents in a camp that is considered important by the parents and how much they are willing to pay for a week. To answer this, were an inquiry send out to 86 respondents.

The edge or the fringe of the city is often the first part of the city we encounter, and our perception of it will probably color the image we make in our minds of the city as a whole. Even though the fringe of the city is important to the image of the cityscape it has not very often been the direct object of attention either in planning, building or even in the heads of the masters, when big ideas were formed. More often than not the fringe seems like something that just happened over time due to separate landowners, businesses or actions of other financially strong operators. The aim of this essay is to try to describe the history of the city edge in Sweden, from the very first town in the 10th century until today?s expanding mosaic of different ideas and styles as well as to bring some clarity and order into some of the different ideas and ideals in the planning of the edge in different eras and to review how the edge has been shaped and used.

3D-modelling in AutoCAD This thesis is done in cooperation with LB-Hus in Bromölla, and have aimed to establish a digital AutoCAD model of one of the company?s house types and to find out what opportunities there are to do visualisations in the form of images directly from the programme. Modeling has been carried out so that the very construction of the house is included. Interiors and installations, with the exception of the ventilation system, have been left out in the model. The model has been created with solid models after a comparative study made between solid models and surface models to find out which option in this case was the easiest to handle and took up the least space.

Computer Forensics investigations have become more and more common while investigating IT-related issues. From experience, hard disks, USB thumb, memory sticks contains information that might be useful. Computer Forensics is regulary conducted by Police, Customs, Tax investigators but also within private companies and organisations. However, there are areas within the storage device that are not part of the organisied structure that a file system gives. The reason for that might be that the information has been erased by intention, a virus destroyed the file system and so on.

During 2010, 1446 people committed suicide in Sweden. Research shows that groups that are less favored in society have an increased risk of suicide. Social services often encounter groups of people that have a high risk of suicide, for instance welfare recipients or substance abusers. The purpose of this study was to shed light on how social workers talk about suicide and how this might affect interactions with suicidal clients. The study is based on qualitative interviews with five social workers in Stockholm.
