En jämförelse mellan vakuumisolering och traditionell isolering
The purpose of this thesis is to investigate if vacuum insulation panels are a competitive alternative to traditional insulation.Vacuum insulation has been used as insulation in buildings in Germany and Switzerland for a few years. In Sweden the high-performance insulation material is mainly used in refrigerators, freezers and vacuum thermoses. The development is proceeding well and vacuum insulation is becoming more common in the construction industry. Since it is a relatively unexplored material on the market there are many flaws and problems with the material.The questions we have chosen to answer in this report include an increased knowledge of vacuum insulation, various problems that may arise when handling/installation and the pros and cons of vacuum insulation compared to standard traditional insulation.The methods we have chosen to use in this report is a literature study, interviews with various suppliers and manufactures and calculations to show the differences between traditional and vacuum insulation. Vacuum insulation is 5-10 times better insulation than standard traditional mineral wool insulation, mainly at the beginning of its lifetime.Vacuum insulation panels (VIP) have a service life of approximately 50 years, whereas traditional insulation has a service life of approximately 100 years.

Huvudhalscancer och livskvalitet : Patientens skattning av livskvalitet innan och efter strålbehandling
Introduction: Each year 1200-1300 patients are diagnosed with head neck cancer. Treatment that involves radiotherapy can cause severe side effects for example trismus that affects quality of life.Purpose: To study health-related quality of life in patients who have undergone radiation treatment for head and neck cancer and participated in a intervention group who received training intended to prevent trismus or in a control group who received standard treatment.Method: This is a prospective study in which data is collected from 66 patients participating in a randomized study aiming to evaluate a training program to prevent trismus. Thirty three participated in the intervention group and thirty three in the control group. Both patient groups assessed health related quality of life (HRQOL) with EORTC QLQ C30 and QLQ-H&N35, at start and end of the radiation treatment, and at 3 and 6-months after completing radiation treatment.Results: There is no difference between the intervention and control groups regarding symptoms, functional status and global health, except for intake of nutritional supplements. For both groups almost all scales measuring HRQOL deteriorated under the radiation treatment. However, 3 and 6 months after end of radiotherapy HRQOL had improved and had returned to the baseline values.

Att åka berg- och dalbana : en resa från barndom till vuxenliv med fyra vuxna barn till missbrukare
The aim of this degree project is to find out how people who have grown up in families with addiction problems have experienced their childhood and how their adult life has been affected by this. With the help of qualitative interviews with four grown up children to addicts, knowledge has been gained about what was experienced as problematic during childhood, what was beneficial and compensatory as well as how they feel today. The results have shown that their childhood was affected by a deficiency in the ability to parent, weak networks, adjusting, responsibility, a feeling of being left out and few positive experiences. Factors that have been protective are: important people, interests as well as attitude. In adult life many habits from childhood remain.
Utan biblioteket, det är tråkigt En grupp flerspråkiga barns interaktion med tre bibliotek
The aim of this study is to examine the interaction between a group of multilingual, twelve-year-old children, and three libraries. The children live in a suburb of a larger city. The three libraries are their school-library, the library in their suburb and the main library in the city. We have examined if and how the children use the libraries, what the libraries mean to them in their daily life and what their possibilities are when it comes to participate in and influence activities and collections at the libraries. We have pursued qualitative interviews with sixteen children in grade six and three librarians, working with multilingual children at the three libraries.
Då, nu och science-fiction : En studie av skönlitteraturens potential att utveckla elevers historiemedvetande
Denna studie undersöker skönlitteraturens potentiella möjlighet att utveckla historiemedvetande hos elever på svensk gymnasieskola. Syftet med undersökningen är att se om den skönlitterära författaren skapar förutsättningar för historiemedvetande och i så fall hur samt visa på hur skönlitteratur kan användas i en ämnesövergripande svensk- och historieundervisning enligt Gy11. Två romaner undersöks, den historiska romanen Boktjuven samt science-fiction-romanen Hungerspelen. Dessa romaner dekonstrueras med hjälp av analysschemat Inomvetenskaplig och utomvetenskaplig historieskrivning för att se om romanerna kombinerar historieförmedlande och skönlitterära grepp i en växelverkan mellan distans och närhet, något som enligt Carina Renander kan leda till ett potentiellt utvecklat historiemedvetande. Resultatet från denna analys kopplas sedan samman med Gy11 och exempel på undervisningssituationer presenteras.
Tänja tiden ur sin buk : Nattens skogar och historia
In this essay I trace the historical theme in Djuna Barnes?s Nightwood, stressing the importance of the concept of forgetfulness in the text. Read alongside Nietzsche?s On the Use and Abuse of History for Life as well as his later thoughts on genealogy, the novel can be seen to concern itself with that same dilemma of history that he articulates in his philosophy. That is: how not to be overburdened by historical knowledge to the point where it petrifies life and prevents any real and novel action, and how at the same time, to make oneself conscious of ones own historicity, so as not to be governed to much by the past.I argue that Robin inhabits what Nietzsche would call the unhistorical state, whereas the other characters, in contrast, struggle with their relation to the past.

Upprustningsmetoder för en bankropp : En jämförelse ur ett LCC-perspektiv
In recent years, the Swedish railway track system has been neglected in terms of capacity and maintenance. To adapt the existing system to current traffic load there is a great need for extensive improvement and maintenance. Shortcomings are especially occurring on older embankments running over soft subgrades. To select the most suitable method for reinforcement of the embankment, it is important to evaluate different solutions from a life cycle cost perspective. In long-term perspective, it is often shown that a method with low investment cost causes a higher maintenance cost and a shorter technical lifetime.
