The thesis aims to compare differentpiping materials in heating systems interms of cost as well as to illustratethe impact of energy characteristics ofdifferent materials over its servicelife. The methods used for costcalculations regarding piping are alsoto be examined to highlight thedifferences between template basedcalculations and more carefully executedones. The work is delimited to discusspipes of steel, copper, plastics andcomposites. The aim is that the resultcan be compiled to illustrate the prosand cons of various materials whenevaluating investments.The main object of the survey is part ofa heating system in the office-block KVSommaren located in southern Stockholm.The configured piping system is designedwith the mentioned piping materials andis used to make up the data for flow andcost calculations. The differentmaterials are calculated in both aconventional manner with a supplementarycost for additional fittings and with amore accurate quantification of thecomponents.

I den olfaktoriska litteraturen finns olika åsikter om huruvida människor kan bibehålla en mental representation av en doft. I denna studie undersöktes hur bra vi är på att föreställa oss dofter jämfört med bilder av personer, med hypotesen att denna förmåga är sämre för dofter än för bilder. Deltagarna försökte namnge 40 personer (bilder) och 40 lukter, där den ena gruppen endast exponerades för stimuli i 4 sekunder (singelsamplingsgruppen), den andra fick obegränsad tillgång under hela namngivningsförsöket (multisamplingsgruppen). Grundantagandet är att om deltagarna kan föreställa sig ett objekt för sitt inre så är de inte så beroende av återexponering. Resultatet visade inte på någon signifikant interaktion mellan grupp och modalitet, men nominellt går resultatet i hypotesens riktning.

AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.

Förståelsen för andra människor som krävs för lyckade interaktioner, förklaras i attributionsteorierna "Theory of Mind" och "Simulation Theory. Ett vanligt men ouppklarat fenomen är det fundamentala attributionsfelet, där beteende felaktigt attribueras till inre generella egenskaper. Fenomenet reflekterar en abstrakt mental konstruktion i enlighet med Construal Level Theorys antagande om hur psykologisk distans inverkar på perception. I en modifierad Attitude Attribution Paradigm modell undersöks om spatial distans påverkar det fundamentala attributionsfelet och om skillnader föreligger mellan kvinnor och män. Kort/lång spatial distans primades genom en kontroversiell text, via information om dess kompositionsplats, som fungerade som underlag för bedömning av skribentens åsikt.

This report deals with handling and interim storage of soils which are planned tobe reused in construction works. The types of soils that are dealt with are gravel, topsoil and sand. The thesis work has been carried out in collaboration with Skanska Sverige Väg och Anläggning Sydost. The main goal is to find an area for using to store soil in between projects.Studies of laws and regulations regarding exploitation and storage of soil has led to a theoretical background upon which the report is based. Background informationhas also been gathered in meetings with the employees at Tekniska Kontoret and Länsstyrelsen in Jönköping.On the basis of literature studies results, a general template has been developed for which desirable properties a possible location should meet.The model was applied to find a number of possible options in the vicinity of Jönköping.

The aim of this report was to investigate the economy of passive houses. The work was focused on economy in total and on the economy of different components such as windows, insulation, heat exchanger and the air tightness of the climate shell. No attention was paid on the comfort factor or to the impacts on the environment.Two houses, aspiring to be passive were chosen; A big one and a small one. Hence, comparisons considering the size of the building have been possible to do as well.The comparisons were made by calculating ?break even? between two concepts; passive and BBR- concept.

Abstract    Objective: The aim of the present study was to investigate if inclinometer estimates of arm posture during paper mill work differed between periods of different arm visibility. The aim was also to identify strategies for and difficulties in assessing body-visibility on video. Methods: The study consisted of two parts, where part 1 aimed to investigate the validity of observation-based assessment of arm posture during paper mill work. Study 2 was a survey among people with experience in assessing the posture of paper mill workers from video. Results: The total time for the right upper arm visibility indicates that it was on average visible in 54%, partly visible 15 %  and not visible 31%.

Stress is common in today?s society, but the word stress has numerous connotations. The aim of this study was to investigate how dogs are effected by stress and what the veterinary nurse can do to help dogs to avoid or at least mitigate stress within the veterinary hospital. The goal was also to see how dogs perceive the environment in the veterinary hospital and what behaviours dogs demonstrate when they enter the hospital and during their stay. Studies have shown that dogs have a reluctant feeling on entering a veterinary hospital. They can feel stressed by coming to a new environment, as well as by being put in a cage with no control over what is going to happen to them.

The aim of this study is to map the consumption patterns of the poor. We also examine if loyalty can be created in this segment, and try to discover different types of poverty. This study is of great importance since the poor segment has been slightly overlooked in marketing research. Therefore we have also turned to other academic disciplines such as sociology, ethnography and consumer culture in order to analyze our empirical input. The study is abductive and we have in a qualitative and ethnographical manner conducted interviews in order to obtain information and reveal categories.

In this multistudy the aim was to measure the effect of mindfulness and yoga in negative stress. Is it possible for yoga and mindfulness to increase awareness and acceptance to inner and outher circumstances? Mindfulness-Based Stress Reduction (MBSR) has shown good results in how to cope with negative stress and how to stay calm in a stressful envirorment. The qualitative study where Visby Yoga Center and Stockholm Yoga Shakti attended in a survey. Correlation showed no relationship between stress and mindfulness and no significant value, n=20, Cohens d=0,16.

The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background knowledge.The tenant-owner?s association Duvan at Petterslundsgatan in Uppsala installed year 1999-2000 a geothermal heating system. The purpose of this installation was that they hoped it would lead to a smaller usage of district heating which would lead to a reduction of the heating expenses for their buildings. The geothermal heating system consists of 19 energy wells and 4 geothermal heat pumps, and it is one of the first systems of that size in the region of Uppsala.

The purpose of this paper is to give a view of how violence and victims has been portrayed in novels. I have chosen 6 books where the main character is a child who has been exposed to physical, mental and/or sexual violence. I have asked questions to the book and I have tried to find patterns in the child's strategy to cope with violence and how the violence is described. I have also written two chapters about earlier studies of this field and theoretical standpoints. The main perspective I present is the salutogenese perspective and how people create meaningfulness in their lives.The children in the books have different ways to handle their situations.

The aim of the study was to describe parents' experiences of empty nest. The sample consisted of individuals who had experienced one child moving out of the parental home. Data were collected through qualitative semi-structured interviews and were analyzed by using thematic analysis. The thematic analysis revealed four themes, Concerns about the new time in life, Changing roles, Socializing in the family and Testing the relations. Due to the themes participants' stories reveal anxiety facing the time that will come when children takes the step to leave the nest.

The aim of this thesis is to discuss and analyse the media debate about feminist self-defence, by pointing out the pros and the cons. The arguments in favour could be separated into three different parts: statistical arguments, psychological arguments and justice arguments. The counter arguments could also be separated into three parts: general arguments, violence-related arguments and gender-related arguments. In short, feminist self-defence is built on women's experiences of men's violence. It contains three different parts to help women avoid violence, threat of violence, insult and sexual harassment.

 Like adult obesity, childhood obesity prevalence is rising, especially in the Western World.As many as 20 ? 25 percent of the ten years old children are overweight in Sweden. It isimportant to early identify overweight, since overweight could lead into diabetes, mentalsuffering, hypertension and cardiovascular disease.The aim of this study was to describe how nurses experience and perceive the conversationwith parents of overweight children. A qualitative method with a content analysis has beenused. Six nurses working in child health centre have been interviewed.The result shows that the conversation between the nurse and the parents of an overweightchild can be very difficult.
