This paper deals with the opportunities for the technique of Condensation, for wood fired household heaters, on the Swedish market. In this project the condenser is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied. The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low temperature of the water going into the stove, from the condenser. In addition to this the wood was not of highest quality and the stove could have needed some maintenance before the tests.

Ett mycket högexploaterat förslag utformas där en egen identitet skapas åt Arenastaden i Växjö. Solens gång, bullerkällor, brandrisker, kulturhistoriska värden och många mål i kommunens visionsbild för Arenastaden väger in vid utformning av förslaget. Förslagets nya upplevelsevärden och andra kvalitéer analyseras med hjälp av en solstudie, bullerkällsundersökning och analysmetod av Kevin Lynch. Projektuppgiften är baserad på att en mycket hög exploatering drar ner på områdets upplevelsevärden. Då analysens resultat föll annorlunda erhölls ett annat resultat ? metoden; att bygga på höjden besparar grönytor och de värden som mäts vid en Lynchanalys..

This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.

Humidity problems and poor ventilation are factors that we associate with poor indoor airquality which are known to negatively affect health. Such problems have decreased with timein Sweden but, in other countries this is still a major problem especially during winter. InChile, this is most common in the central regions of the country, especially the Strait ofMagellan. This issue is primarily due to surface Condensation happening indoors which bringsabout dampness which facilitates the growth of fungus and stains, foul odors, metal corrosionand more. This is due to a combination of poor ventilation and insufficient forms of heatingalong with buildings which have no insulation.

The essay's aim was to see which attitudes county council's and municipality representatives had about themes like: collaboration and competence in the work around double diagnosed persons. Its objective was to zero in on the attitudes of the representatives regarding a coallocated collaboration project in Stockholm. Also, it sought to find out what attitudes the representatives had about the other representatives attitudes concerning the above mentioned themes. A number of attitudes were presented during the qualitative interviews with the representatives, highlighting which attitudes seemed strongest. Then the interviews were analyzed using meaning Condensation and then set against the theory of social representations.The analysis showed that before work with the target group starts, there?s a need for synchronization of the different representatives involved in the collaboration project.

The aim of this study was to, from a special educational approach, describe and analyse nine teachers and headmasters experiences and perceptions of the use of laptos, ?1-1?, as a tool for working with 13-16 year old pupils born outside of Sweden and with special educational needs (SEN). Interviews were used for data collection. The interview material was analysed with the phenomenografic analysis method and with meaning Condensation method. The result was analysed through three perspectives on special education and the concept of inclusion as the study?s frame of reference.

Background: In studies about Romani people?s health, it becomes clear that the Romani inseveral countries have a poor health and avoid seeking health care.Objective: The purpose of this study was to explore Romani men's experiences of treatmentin the Swedish health care.Method: A qualitative interview study was conducted with respondents about theirexperiences in individual interviews. Seven male Romanis were elected with a purposefulsample. A content analysis by systematic text Condensation on the data obtained was made asdescribed by Granheim & Lundman (2004).Results: The summed up impressions of the responses was perceived to be good, however,many men believe that the information is inadequate. Staff at the emergency department inUppsala should listen more to patients.

Vattenfall district Heating power plant in Uppsala produces district cooling with absorption heat pumps which leads to a large amount of waste heat that has to be cooled with evaporative cooling towers. The Environmental Court has ordered Vattenfall to survey the possibilities to recover the heat, which is the focus of this thesis.The study begins with an overview of the system, and conditions and limitations for waste heat recovery is examined. In the next step alternatives to recycle the heat is evaluated, either by direct recovering or by upgrading.First, the technical possibility of each alternative is discussed, and then the operation time and the amount of recovered heat is calculated. Those alternatives which are possible are brought further to an economic analysis.The cost of investment for each alternative constitutes the basis for a present value analysis. The results are put together in a table where the total amount of recovered heat is compared with the present value for the different alternatives.

Bakgrund: Måltidsmiljön och personalens agerande under måltiden påverkar gästens fysiska välmående och nutritionsstatus. Syfte: Att observera om följsamheten till riktlinjer för nutrition förändras efter en intervention med fokus på den sociala interaktionen och serveringen vid måltidssituation. Metod: Fältanteckningar från måltidsobservationer genomförda på två boenden analyserades enligt Systemic Text Condensation (STC). Denna innebar att identifiera teman, meningsbärande enheter, koder och underkoder för att slutligen resultera i en syntetisering som representerade innehållet i fältanteckningarna. Interventionen bestod av handledning av personalen under ett år.

There exists a great need among companies and other organizations to be able to visualize statistics. It?s also increasingly common to ask for web-based solutions for increased flexibility and accessibility for users. This paper describes how large amounts of geovisual data, for a large number of regions, can be visualized in an interactive and well-presented manner. The paper let?s you walk through two application scenarios, developed in a Flash environment, using the GeoViz component library for visualization. The first application has been developed for Statistics Sweden (SCB), to give a solution on how to visualize statistics for Sweden?s zip code regions.

Background: An increasing number of operations on children are performed as day surgery and this experience of health care may affect future hospital stays. The aim of this qualitative study was to describe children´s experiences in connection with day surgery. Method: Ten children aged six to fifteen who had gone through general anesthesia at examinations or surgery were interviewed and the content was analyzed by systematic text Condensation. Result: The core category ?From uncertainty to relief with newly acquired experience? could summarize the result of this interview study.

Transient driftförhållande blir allt mer intressant för forskare och tillverkare och de största svårigheterna är att minska emissionerna utan att påverka bränsleförbrukningen eller motorns respons vid gaspådrag negativt. Huvudmålet med det här examensarbetet var utvärdera olika metoder för att mäta NOx och antal partiklar med hög tidsupplösning för att möjliggöra studier av emissioner under transient driftförhållande.I arbetet har en Horiba MEXA 120NOx NOx-sensor studerats med avseende på linearitet, mätsäkerhet och responstid. Försök för att öka noggrannheten har också gjorts genom att kompensera för varierande skalfaktor för utsignalen och för responstiden.Ett spädsytem har arbetats fram för att ge hög tidsupplösning och god repeterbarhet. I detta ingick en Rotating Disc spädare och en två-stegs Dekati spädare. Spädsystemet var kopplat till en TSI Ultrafine Condensation Particle Counter 3025 A (CPC) och var nödvändigt för att hålla koncentrationen inom det mätbara området.

The purpose of this study has been to analyze how managers within the elderly care who operate according to the Social Services Act work to support the assistant nurses with the social documentation. In order to achieve my purpose and to be able to answer the research questions, a qualitative approach was selected. My empirical material consists of seven interviews, four with assistant nurses and three with managers. Anthony Giddens? structuration theory in Månsson, (2003 s. 422) has been my theoretical starting-point and the concepts of practical and discursive consciousness have been used in the analysis.

Svenska Aerogel AB has developed the material Quartzene® which is of the typeprecipitated silica and contains calcium - magnesium silicate ((Ca, Mg) SiO3). Thematerial is used for molecular filtration of contaminated air. Qartzene?, which is inpellet form, is porous and has a high internal surface which is a requirement for themolecular filtration. With the use of various impregnations, filtration can affect thedesired outcome.

Today there is an increasing market for businesses concerning horses, and since we are already running such establishments we sort of speak already have a finger in the pie. Due tothe increasing competition and demands, new and more practical constructions have become a necessity. In doing this project I wanted to make a comparison between having a stable integrated with a manege and having both constructions kept separate. I wanted to compare different layout and make an estimate of costs to see which solution would be less expensive and better with regard to working environment. I will further also deal with different ventilation-systems andlight transmissions.
