Passivhus : En jämförelse mellan olika byggnadstekniska lösningar för ytterväggar
This report aims to examine the design of a passive house. The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.
Sjuksköterskors upplevda stress och stresshantering. En empirisk studie.
The purpose of this empirical study was to investigate if stress exists among nurses, and if it exists how do they experience it and how do they cope whit it. The nurses also got to define the word stress. Karasek and Theorells demandcontrollmodell were used as a theoretical framework. The result of the study answers our research questions and gives us a good insight how the nurses experience stress and how they cope with it. The result shows that 56 of 60 nurses indicated that they experience medium to high level of stress a couple of days a week or more often and that it affects their work.

Lanczos potentialer i kosmologiska rumtider
We derive the equation linking the Weyl tensor with its Lanczos potential, called the Weyl-Lanczos equation, in 1+3 covariant formalism for perfect fluid Bianchi type I spacetime and find an explicit expression for a Lanczos potential of the Weyl tensor in these spacetimes. To achieve this, we first need to derive the covariant decomposition of the Lanczos potential in this formalism. We also study an example by Novello and Velloso and derive their Lanczos potential in shear-free, irrotational perfect fluid spacetimes from a particular ansatz in 1+3 covariant formalism. The existence of the Lanczos potential is in some ways analogous to the vector potential in electromagnetic theory. Therefore, we also derive the electromagnetic potential equation in 1+3 covariant formalism for a general spacetime.
Laserprojektor
This report describes a thesis project on 15hp. The purpose of the thesis project is to build a laser projector that reacts on sound waves and thus get a laser beam to draw visualizations of sound waves on a wall. The idea was that the design would be independent and not have to be plugged into any audio equipment. This was achieved by absorbing sound waves into a microphone. Another factor was to get a ?do it yourself? -feeling of the design and therefore it was chosen to be constructed using for example, old hard-drives.The result was a relatively large and bulky designed laser projector that can draw sound waves on a wall..
Barn och stress - Specialpedagogens roll i det förebyggande arbetet/Childern and stress - the roll of the education teacher in the stress prevention
Sammanfattningvis visar resultaten på att barn och ungdomar är och upplevs mer stressade idag. Det finns många orsaker till barns stress och och den tar sig i olika uttryck. Skolans inre och yttre miljö är en stor stressfaktor som påverkar både yngre och äldre barn. För att kunna förebygga och motverka stress är det viktigt att identifiera stressen tidigt i livet..
Stress. Ur ett kvinnligt perspektiv
Stress är ett samhällsproblem som påverkar människan fysiskt och psykiskt. Att dessutom vara kvinna kan upplevas som extra kravfyllt då samhällets normer fortfarande klassificerar mannen som normen. Stress är ett fenomen som är svårt att påvisa då alla individer upplever stress på olika sätt. Detta problematiserar troligtvis forskningen då stress inte är påvisbart i samma utsträckning som andra företeelser. Dock har det gjorts en hel del forskning i ämnet och det finns även pågående forskning.
En plats - En identitet
We live in a society where we are not bound to one place. We are encouraged to be mobile and constantly moving between different locations. The life in a convent is a contrast to this; nuns live at a specific place they are bounded to by vows and can not leave. The sisters in the convent of St. Birgitta, Pax Mariae have promised to stay at the same place and live by the rules of the convent.
Beräkningsmall för väggskivor enligt Eurokoder
The regulatory framework for constructional calculations in Sweden did expire In January the 1.st, 2011.Since then the constructional regulatory that originally were composed by Boverket (BKR) has been replaced by new common range (Eurocodes) for the entire European Union. This transition has led to changes in existing rules and standards regarding dimensioning area in Grids and has forced a need for updating to structural Engineers.The new calculation system has caused time-consuming studies of the new rules and a proper understanding of all the advice and regulations for the entire profession.This study has been carried out in cooperation with the firm "Knut Jönson Ingenjörs AB i Stockholm?, that has been affected by this transition as all other consulting firms. The firm has requested for a calculation method of wall beams according to Eurocodes. The study's focus is therefore to clarify the rules and guidelines regarding the design of wall beams according to the new regulation.
Klättring i skolan : En studie om klättring som en del av den svenska idrottsundervisningen
AimThe aim of this essay is to investigate the possibility to exercise climbing within the framework of the physical education in the obligatory school. We investigated how physical education teachers think about exercising climbing in school and how the Swedish Climbing Association is working to reach out to schools.MethodA questionnaire was sent out to 81 schools (Idrottshögskolans partner schools) in suburban Stockholm, which corresponds to 10% of the total amount of schools in that area. A mail interview was also made with a representative for the Swedish Climbing Association who also represented a local climbing association, to collect information about how they worked with schools and youth.ResultsWe have not found anything in the steering documents against exercising climbing during physical education. There are obstacles for exercising climbing during physical education, a wall for climbing is very expensive and the schools have a lack of space for this wall. The results from the questionnaire showed that 76% of all the schools that did not have a wall for climbing wanted to have one.
Gallery Wall
För vissa är graffiti konst, för andra är det ett tecken på förlorad kontroll. För mig är det ett redskap för att mötas. Jag har delat in mitt examensarbete i två delar. Den första behandlar visionen jag baserat mitt arbete på. Den andra handlar om design och placering av de fysiska paviljongerna. I den första delen har jag utgått ifrån ett scenario där den fysiska arkitekturen återspeglas i ett virtuellt gallerisystem jag get namnet Gallery Wall. Denna del finns bara på idébasis men har varit utgångspunkt då jag formgivit mina paviljonger. Jag har skapat fem olika paviljongstyper som tillsammans på ett teoretiskt plan utgör en och samma virtuella huvudform.I, eller rättare sagt på, paviljongerna ges tillfälle för vem som helst att måla och presenteras sin gatukonst. Min förhoppning är att mina paviljongtyper skall inspirera andra att bygga egna varianter som alla är del av Gallery Wall.

Background: The stress in the society seems to having become more amplified and more trying. Statistics show that the appearance of stress related industrial diseases have increased strikingly. What can be stressing at the workplace? The work conditions are not the only thing that causes stress but no matter what the causes are employers have to restore the employees to their former positions. How are companies dealing with the problems of stress in reality? Do they have formulated strategies for how to manage the problems? Purpose: The purpose with this essay is to try to see pattern in how companies manage and treat stress and stress related industrial diseases.
Krisen på Wall Street : En analys av sju artiklar från tidningen Affärsvärlden och fem artiklar från tidningen XINHUA om banken Lehman Brothers konkurs 17 september 2008
The crisis on Wall Street. This essay is a comparative study of how two business newspapers report on the bankruptcy of Lehman Brothers Holdings in September 2008. Seven articles from the Swedish European financial newspaper Affärsvärlden (Business World) and five articles from the Chinese-Asian news agency XINHUA FINANCE are examined. The aim is to analyze, understand and evaluate from a rhetorical perspective. My thesis is that rhetors storytelling can tell us more about how we cope with crisis in the global economic discourse. The texts can portray man as a narrative creature when identification as a rational actor is not enough. The analytical methods used are linguistic analysis with an emphasis on metaphor analysis, narrative analysis based on pentad - Critical dramatism, and discourse analysis with doxological outlook. The results show that both newspapers seek to defend the global economic discourse, but they do so in different ways. Affärsvärlden advocates calmness and conveys a cautious attitude. The heart of the crisis, as well as its solution, is on Wall Street. XINHUA advocates control and expresses confidence in authorities and the system. Asia is presented as Wall Street's savior..
Passivhus, detaljutformning och dess köldbryggor
Along with rising energy prices and increasing awareness of environmental issues, the criteria for buildings energy performance have been sharpened through the years. Today, ?passive house? and ?low energy house? are commonly used phrases in the construction industry and is expected to become increasingly common in the future.For houses with well-insulated building envelope the importance of well constructed details increases when minimizing the heat losses. Examples of these details are floor-wall junction and window openings in the wall. In such connections thermal bridges occur, which means that heat more easily is transported out of the building, compared to the rest of the building envelope.This report deals with detail solutions around windows and a comparison between a traditional slab and a foundation from Koljern consisting of foam glass.
Barns medvetenhet om stress: en undersökning på en begränsad barngrupp
I dagens samhälle möts barn av enorma krav från olika håll, skolan är en stor del i barnens liv, och vi har i denna uppsats fokuserat på hur barn upplever stress och vad som orsakar deras stress. För att ta reda på detta har vi använt oss av den kvalitativa metoden i form av intervjuer med barn och en pedagog. Problemformuleringarna vi har använt oss av består av dessa frågor: är barnen medvetna om sin egen stress? Hur känns det i kroppen då de är stressade? Och vet de varför de är stressade? Resultatet av vår undersökning visar att vår barngrupps medvetenhet om stress inte är särskilt stor. Barnens svar kretsar runt tid och vuxnas stress, av 11 intervjuade barn var det endast tre som kopplade stressen till sig själv och beskrev sin egen stress..
