Livscykelanalys för koldioxidutsläpp från flerbostadshus
Today, about 15 to 20 percent of Sweden?s total emission of carbon dioxide can be traced to the household sector. By examining apartment blocks in a life cycle perspective, the origin of the carbon dioxide emission has been charted and analyzed. This information has been used to create a computational model that calculates the total emission of carbon dioxide from a specific apartment block. The results from the analyzed apartment blocks indicate that both the use of energy and the emission of carbon dioxide have been reduced since the 1960s. Through the examination of building materials, it is possible to lower the emission of carbon dioxide that origins from the construction phase of an apartment block.

The costs for specialized health care was divided into three different subgroups; independent somatic specialized health care, specialized health care provided by private practices or outside the region and psychiatric specialized health care. The data was age-standardized.
Källsorterade systems påverkan på avloppsreningsverk : växthusgaser, energi- och resursanvändning i modellstudie
The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.

Common misconceptions about everyday astronomy-related phenomena among students in the 9th grade
Students of all ages host a wide variety of scientifically inaccurate ideas and conceptions about everyday astronomical phenomena, such as the seasons, the moon phases, and gravity. The field of Astronomy Education Research has over the last decade experienced an accelerating growth, although the majority of studies have been conducted in the USA. In this work, the 9th grade students of a typical Swedish school were surveyed by means of a questionnaire in order to probe their conceptual understanding of several key concepts in astronomy. In the end, the number of respondents amassed to a total of 90. The results were analyzed with a constructivist approach in light of conceptual change theory and phenomenological primitives.
Interaktionens betydelse i distansutbildning. Studenternas upplevelse av interaktionsdimensioners påverkan av sammankomster i en distansutbildning
The purpose of this study has been to create a better understading of how face?to?face activities in course´s impacts on the experience of interaction within a course.More specifically, the study puts the student'?s perception of how mandatory face?to?face activities affect and are affected by the interaction in focus. This is done by the following research questions. What affects the student'?s perception of face?to?face activities? Which interaction dimension affects the factors that influence students perception of the activities? Which interaction dimension is influenced by the student'?s perception of the activities?The theoretical base is Wagner'?s (1994) three types of interaction and Andersson´s(2003) theory of interaction dimensions.
Effects of Driver, Vehicle, and Environment Characteristics on Collision Warning System Design
The purpose of the present study was to examine effects of driver, vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ?risk? and ?safety margin? respectively. Rear-end collision had a stronger focus in the present study.
Logistiska lösningar för en lönsam byggprocess
This is a study, the purpose of which is to investigate how the construction company Sefab Bygg AB is able to increase its profitability and render a more efficient production process through logistic solutions. The study is made during one of Sefab´s present projects. The project includes sanitary renovation of 650 apartments in the co-operative Opalen in Norrköping.To find out whether changes of logistic routines are profitable or not, it?s necessary to evaluate the total cost of the changes. A total cost analysis is a mapping of all the costs for a particular material, on one hand for the present situation and on the other after the change.
Welfare impairment of lambs around weaning. Play and other behaviour indicative of affective state
The abrupt and early weaning of intensively kept lambs may have serious animal welfare implications, but relatively little is known about this. Weaning includes the breaking of the mother-young bond and abrupt replacement of milk by solid food, often coinciding with changes in the (social) environment. Altogether, these changes are likely to affect lamb welfare significantly. This study aimed to establish how strong and persistent lamb welfare is impaired following abrupt weaning by means of measuring behaviour parameters indicative of affective state. Also, we investigated the existence of a diurnal rhythm in play behaviour, which is considered an important indicator of positive affect and good welfare.
Att öppna texten för det främmande : en studie av litteraturens gränser och möjligheter vid gestaltningen av det främmande och annorlunda, den andre och av lidande.
The aim of this study is to examine ways of writing experiences of the strange and different, experiences of the other in his or her otherness and experiences of suffering. The study focuses possibilities and limits for the writing of these experiences and aims at finding a tangible way of writing literature. Part of the aim of this study is to elaborate a proposal for a way of writing experiences of the strange and different, experiences of the other in his or her otherness and experiences of suffering. The material for the study consists of three different approaches to literature, in which theories on literature or analyses of literary works are presented. This material is initially analysed in separate analyses in which conceptions, strategies and methods for writing experiences of the strange and different, the other and suffering are identified. Secondly, the material is analysed in a comparative analysis, aimed at finding similarities and differences between the approaches but above all to let the approaches supplement and challenge each other.
Feedback ur ett ledningsperspektiv: en fallstudie inom bemanningsföretag
Syftet med den här uppsatsen var att belysa hur ledningen i bemanningsföretag ger stöd till anställda genom feedback. Uppsatsen börjar med att vi tydliggör ett praktiskt problem som är vanligt förekommande inom bemanningsföretag. Vi illustrerar detta problem med en figur som åskådliggör en distans mellan bemanningsföretagen och dess anställda. Den här distansen kan emellertid leda till bristfällig kommunikation mellan parterna och för att minska sannolikheten att detta uppstår, kan ledaren i ett företag stödja de anställda genom att ge feedback. I teorikapitlet utgår vi från en modell som visar de faktorer som bör beaktas, det vill säga 360-gradersfeedback, coachning, uppmuntran till dialog, självkontroll samt lärande organisation.
Är plöjningsfri jordbearbetning bättre än konventionell plöjning? :
The background of this study is the fact that it nowadays is more common to grow wheat after wheat. Usually we plow every autumn to remove the straw, and we wanted to study the effect of alternative methods to do it. We have done this experiment to answer the question if no tillage is better than conventional plowing. The results of the field experiment indicate that there is a link between plant establishment and the choice of equipment, but also a higher weed pressure in experimental plots with only ground tillage. The equipments which left much straw on the top of the ground the problems with fungi were more severe.
Noggrannhet vid målinmätning : Analys av ett eldledningsinstrument med förbättringsförslag
This Master Thesis has been conducted as an assignment of the Swedish Defence MaterialAdministration and the Swedish Armed Forces and aims to examine the Target Location Error(TLE) of a Forward Observer System. The targeting accuracy of the system is vital if the systemis to be used as a sensor for precision munitions. The analyzed system, EOI (FOI 2000), wasdelivered to the Swedish Armed Forces in 2007. The targeting sequence starts with deciding theposition of the system with a GPS-receiver, continues with methods where the north direction issettled and ends by measuring the distance, direction and elevation to the target. When allparameters have been measured the system calculates the position of the target.
