Beräkning av värmeenergiförluster i flerbostadshus genom analys av den totala fjärrvärmeenergianvändningen :
This thesis has been carried out on behalf of IV Produkt AB and intends to set an average ratio of thermal energy losses in apartment buildings that were built during the 1960-1990. This shall be derived by analyzing the total district energy consumption that has been divided into three parts: heat energy losses (the actual heating requirements), the heating of domestic hot water and heating energy consumption for the controlled ventilation.Three different residential areas that were built during the years 1962-1966 and one that was built in 1993 has been analyzed. All residential areas are located in Växjö urban and contains between four and six apartment buildings.The analyzed objects have a mechanical exhaust ventilation systems and district heating as the heating method. No own laboratory work or experiments have been done in this thesis, the calculations have been done on the basis of parameters from VEAB, interviews with property managers, and literature studies. By calculations, we have got a result that is reported in Chapter 6.
Design och konstruktion av mätuppställning för induktiv mätning av magnetisk spinndynamik
Development in spin dynamic occurs in the whole world because of therising demands on fast electronic storage for example hard drivesand RAM (Random Access Memory). Measuring the spin resonance of amaterial gives you the insight of the theoretical speed for amagnetic memory. This means the maximum storage speed is below thefirst resonance. All magnetic materials have different propertiesthat will inflict the resonance frequency which brings that theconstructors of memories need to know which magnetic material theywill use to obtain best results. In the market for normal users themaximum storage speed in a RAM memory is 1.6 GHz.
Utvärdering av fosforläckageefter stallgödsling med hjälp av lysimeterteknik : Evaluation of phosphorus leaching aftermanure application using lysimeter techniques
Based on laboratory studies with lysimeters, the concentrations of dissolved reactive phosphorus(DRP) and particulate phosphorus, which is the main part of other P (OVRP), has been studied inpercolating water. The experiment was conducted through irrigation of small soil columnscontaining clay topsoil from an experimental field in Västergötland. Three rain simulations wereconsecutively performed. DRP concentrations in the percolating water ranged between 0.2 - 0.3mg·Lclearly related to the phosphorus concentration in the soil, measured in a soil extract ofammonium lactate (P-AL). Concentrations of OVRP were relatively low and ranged between0.12 and 0.16 mg·Lwas not proven and the experiment may reflect how a relatively slow percolation of water mayrelease DRP.
Integration mellan system : En undersökning av olika framgångsfaktorer
This paper exposes the problems and challenges organizations face when integrating aged systems, web based systems and web services. The paper focuses on how people with different titles in an organization experience systems integration and the factors that contribute to project failure or success. The research methodology used in this is Grounded Theory and the resulting theory of this paper has taken form through the coding of transcribed interviews, which have gone through a constant comparing to other theories in the area of interest, mostly articles about success factors in system integration. The resulting outcome is a success model aimed to describe the underlying indicators to achieve project success.The success model consists of three factors that contribute to success in integration projects. The factors are: globalization, governance and balance.

Strukturell konservering av måleri på duk Studie kring den långsiktiga stabiliteten hos Plextol D 360, Plexisol P550 och Beva 371
In the early 80s, several new synthetic materials have come to be used in the treatment of canvaspaintings, among them Plextol D 360, Plexisol P 550 and Beva 371. Today, many conservatorsfind the information about the long term sustainability of these binding mediums to beincomplete. Evaluation of synthetic materials is mostly done through clinical research, sometimesartificial aging is simulated. The correlation between artificial and natural aging is however notestablished, useful information can therefore be gained through evaluations of actualconservation treatments. The intention of this study is to find out more about how thementioned products perform over time in normal museum conditions.
Utvärdering av befintliga passivhus : En byggnadsfysikalisk bedömning och mätningar om temperatur, och fukt analys på ytterväggarna
Energy price are on the way up to a high level that will not diminish in the future make us to focus more on the sustainable development for a better solution of residential houses. Passive house or low energy housing are one of the solution to make residential more environment friendly, in same time it´s a financial security using less energy, and saving money. The last 10 years in Germany and all around Europe the concept of passive house been developed, and people aim to know more about these concept that leading the market more attractive for passive houses. A passive house is a well designed building highly insulated and air tight with mechanical ventilated system for the whole building envelope that minimizes the use of energy for heating [1].The housing company Mimer has chosen to invest in low energy consumption in every new housing project. These future plan projects are decided to use less than 75 kwh per square meter annually in purchased energy [2].This thesis is about new constructed passive houses, and focuses on the evaluations of the temperature, and moisture condition for attic, external walls and joist.
Från teckning till färdig produktion : en studie av storyboards inom spelfilm och animerad film
In this thesis I focus on the artistry and essential work, behind the scenes that storyboard artists have contributed to, since the early days of film history. The works I will focus on are the important phases of pre-planning of feature films and animated films. I theorize on the aspect of what makes a good story and how it is brought to life on the screen, as well as how the story is actually conveyed with this drawings. The hypothesis maintains the importance of storyboards, as well as defining their main purpose. Using a formalistic point of view and historical argumentation, I examine and compare five different directors´ use of storyboards and how their respective collaborative teams (i.e director of photography, production designer and story artists, editors etc) create each film´s particular nuances and cinematic expressions.
Påvisande av Helicobacter spp hos hund : en metodologisk studie
The purpose of this study was to develop a reliable molecular-genetic method to determine the different species of helicobacter in dogs. The study is part of a larger project to map the prevalence of Helicobacter spp in healthy and sick dogs in Sweden, and to determine the possible connection of Helicobacter spp infection with gastrointestinal diseases in dogs.
Several published studies have reported on the prevalence of Helicobacter spp in dogs. The problem is that three of the most common species are so alike that a 16SrRNA-PCR with sequencing is not able to differentiate between them. In this study, DNA has been purified from samples and then a Multiplex PCR has been performed. Multiplex PCRs use multiple primers in one single PCR.
"Resan till London" : Språk, struktur och kvalitet i fyra narrativa elevtexter i årskurs 6
The aim of the study was to investigate how four pupils in sixth grade use language when writing narrative texts, examined in relation to the typical structure and linguistic features of a narrative text. Another aim was to explore the similarities and differences between texts which received an A or B grade and texts with a D or E grade. The pupils? texts are analysed from a systemic-functional perspective on language and on the basis of the typical structure and language of a narrative text, with the focus on expressions of time, processes, descriptions and nominal groups (cf. Johansson & Sandell Ring 2012).
Explicita och implicita attityder till överviktiga människor
Syftet med studien var att undersöka explicita och implicita attityder till överviktiga människor samt om och i så fall vilken betydelse ålder, kön och vikt har i denna relation till varandra. Utifrån tidigare forskningsresultat om attityder och övervikt predicerades en skillnad mellan explicita och implicita attityder till överviktiga, där äldre har en mer negativ attityd till överviktiga än yngre, att kvinnor är mer negativa än män och underviktiga är mer negativa än normal- och överviktiga. I vår studie användes IAT (Greenwald, McGhee & Schwartz, 1999) för att mäta försökspersonernas implicita attityder och en kort version av ?Fat Phobia Scale? (Bacon, Scheltema & Robinson, 2001) för att mäta deras explicita attityder. Studien omfattade 68 försökspersoner med en medelålder på 32 år och där 31 var män (46%) och 37 var kvinnor (54%).
Ny stamstation i Yttermalung för anslutning av vindkraft : Nätstudie av olika utföranden i normal- och reservdrift
Since 2004, wind power has had the largest installation of new capacity compared to other energy sources in Sweden. Accommodating new wind power may require strengthening or rebuilding of the existing grid in areas where the grid is already loaded to maximum capacity. This master thesis examine the possibility of a new 400/130 kV substation in Yttermalung, Sweden, with a connection to the two neighboring regional grids in Dalarna and Värmland owned by Fortum. This substation would provide a new connection point to the Swedish transmission system as well as an interconnection of the two, currently separated, regional grids. Different expansion scenarios where a substation with and without series compensation or a phase shifting transformer (PST) to control active power flow were studied.
Dimensionering av bärverk av stål : En jämförelse mellan Eurokod och BKR
The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.
Kan spirometri påverka motivationen till rökstopp?
Hälsorisker och lungsjukdomar relaterat till rökning är en sanning som inte kan underskattas. Att den effektivaste åtgärden är att sluta att röka är också ett känt fenomen. Att det krävs en stark inre motivation hos rökaren själv för att lyckas med att sluta att röka är ett annat känt faktum. Vårdpersonalen kan inom sitt hälsofrämjande kompetensområde påverka och förstärka motivationen hos rökare, genom att erbjuda olika rökavvänjningsmetoder. Dessutom finns det möjlighet att genom mätning av lungfunktionen/spirometri diagnostisera eller följa upp en försämrad lungfunktion orsakad av rökning.
Stråldoser vid konventionell undersökning av skolios
Bakgrund: Skolios kan bero på många olika orsaker. Beroende på dess orsak delas den in i strukturell och funktionell skolios. Vid idiopatisk skolios finns ingen känd orsak och dessa patienter utgör 80 % av de strukturella skolioserna. Det är vanligt att idiopatisk skolios upptäcks hos barn som är 10-12 år. Patienter med idiopatisk skolios kan komma att genomgå flera radiologiska undersökningar och det är därför viktigt att använda så låg stråldos som möjligt.Syfte: Syftet med denna litteraturstudie var att ta reda på hur stora stråldoser patienter med skolios får i samband med konventionella undersökningar.
