Modellering och simulering av det evaporativa bränslesystemet i en personbil
This thesis work has been performed at the department of diagnosis and dependability at Volvo Car Company, Torslanda. The background of this project is based on interest in ascertaining how different factors possibly can affect a diagnosis method, which has been developed to find leaks in the fuel tank and evaporation system. According to the OBD II requirements leaks with an orifice diameter larger or equal to 0,5 mm, must be detected. The idea of the diagnosis method is to create an over pressure in the system with an air-pump. The current through the pump is measured and correlates to the power consumed by the pump.
?Den frivillige soldaten.? : Manlighetsideal och legitimitet bland svenska frivilliga soldater samt det omgivande samhället under finska inbördeskriget 1918
This paper examines how the ideal of manhood is portrayed and constructed and how the participation of Swedish soldier volunteers are motivated and legitimatized. The purpose of this examination is to gain understanding and knowledge about the Swedish soldiers in the Swedish brigade, how they legitimatize and motivate their participation and how the ideal of manhood is portrayed and constructed. The study is based on material from the war archive in Stockholm. The empirical material is composed by letters and propaganda material. In the analysis of the empirical study, there have been two theories used which are Eric Hobsbawms historical method and theory about invented traditions and Peter Aronssons historical method and theory about ?historiebruk? and legitimacy.

Abstract______________________________________________________________________Title:A study about creating understanding for different kinds of empowermentLevel:Bachelors thesis in Business Administration, 15 creditsAuthor:Fredrik LegovicSupervisor:Tomas KällquistDate:2014 - JuneAim:The main purpose of this study is to increase the understanding for different kinds of empowerment and how it affects the staff in the public sector.Method:The choice of method was based on the research aim. The method used to meet the objective was qualitative. The qualitative study was conducted with a hermeneutic basis, where individuals were asked to describe their experience of empowerment and how they feel affected of it. This thesis has a deductive approach, where existing theories dealing empowerment formed the basis for the design of interview substrate, which is then paired with the empirical evidence, based on this the conclusions was drawn.Result & Conclusion:What separates the different kinds of empowerment and how it affect the staff depends most of all on how the management chooses to communicate and share information with their staff.Suggestions for future research:A study regarding managers that works with different kinds of empowerment, and how that affects them, could be regarded as an interesting future research.Contribution of thesis:It shows that different kinds of empowerment affect the staff in different ways, which I made clear to the readers.Keywords:empowerment, thinking skills, relations and organizational - structure and theory.
Establishment and evaluation of a Barley starch isolation method with focus on representability
The high viscosity of barley material makes starch isolation problematical using regular methods established for cereals. An adjusted starch isolation method has been set up for barley, based on fractionation and purification. The focus is on attaining truly representative isolates of six flour samples selected for widely differing characteristics within the research program BarleyFunFood (BFF). Beside establishment of the method, this diploma work aspires to serve the BFF with isolated material of sufficient yield valid for further starch characterisation. A pre study was conducted evaluating available wet mixing equipment, experimental conditions and mode of procedure.
Undervisningsmetodens påverkan på skolbiblioteksanvändningen: exemplet problemorienterad undervisningsmetod
This thesis is an attempt to study whether if problem-oriented teaching implies a moreadvanced use of school libraries than other teaching methods.Teachers have been interviewed about what kind of information they and their pupils need,and where they find their information. Another question is whether the problem-orientedteaching method makes it easier for the pupils to find information in school libraries thanother teaching methods do.The result of the study is that a problem-oriented teaching method creates opportunitiesfor the school library to become an important place for information retrieval. This teachingmethod is a major, but not the only determinal factor. Other contributing factors could beteamwork between teachers and school librarians and the existence of learning aids..
Elevers tillämpning av källkritik på Internet
This paper, called Pupils' practice of source criticism on the Internet, is investigating pupils? use of source criticism. The main research question was: how much knowledge pupils from an upper secondary class have about the use of source criticism, regarding examining data from the Internet intended for assignments. Furthermore, developing a suitable method to investigate this was included. The main research question led to further sub questions that aimed to answer to what extent pupils consider source critique criteria as sender, aim, up-to-dateness, credibility and dependence.The study has been conducted by using mixed methods, both qualitative and quantitative methods.
Inomföretagshandel : en deskriptiv studie av de gängse ekonomiska modellernas förmåga att förklara inomföretagshandel
This essay in economic geography describes what intra-firm trade as a concept is and different ways to determine in which cases trade is to be labeled as intra-firm trade (IFT) or not. The method used by the author is most easily described as descriptive. This method was chosen in order to test if existing theories; classic and neoclassic economics, new trade theory and international business studies, are capable to explain the phenomena of IFT. The theories are tested trough primary and secondary literature but also trough reasoning by the author.The conclusion is that the most reasonable way to determine whether trade occurs intra-firm or not, is to decide upon a 5-% rule where it when one part owns 5-% of the voting strength in the other company is to be considered intra-firm trade. This is a conclusion based on several reasons; the strongest one being that a common view on IFT could boost comparative studies as the U.S already collects data based on the 5-% rule.Classic and neoclassic economics are incapable of explaining IFT as aprerequisite for these theories is that markets are perfect.

The FMT-method is a musical form of therapy that targets all functional disabilities.
Underifrånperspektiv - en analys av utvärderingen av demokrati och delaktighetsmålet i storstadssatsningen i Malmö
The Swedish metropolitan politics have had the bottom-up perspective as a major principle to evolve the democratic participation in segregated areas. My objective was to investigate if a bottom-up perspective has been used as a method of evaluation in a sample of 10 evaluation reports made about democratic participation in Malmö.The key questions were; In the evaluations:- How was the bottom-up perspective and related concepts defined?- What criterias and theories were used?- What values surfaced?- What methods were used?- Has a critical approach been used?The method used is analysis using the theories of Critical Social Method by Alvesson & Deetz, Values in evaluation by House & Howe and Choices of perspective by Eliasson.None of the analysed evaluations have used participatorial methods. As participation is defined mainly statistically, the criterias are usually quantitative measurements, though the evaluators agree that democracy is a matter of quality. There is a common lack of theoretical basis of analysis and methodology description.
Behandling av lakvatten med kemiska oxidationsmedel för att delvis bryta ned oönskade organiska förening : en studie utförd vid Hovgårdens avfallsanläggning i Uppsala
A renewed application for environmental permit for the Hovgården landfill in Uppsala shall be submitted before December 2004, therefore the municipality of Uppsala needs improved knowledge of the contents, mostly organic compounds in the leachate and they also want to find a method to minimize the emissions of these compounds. The purpose of this study was to find a practical and economical method based on chemical oxidation using oxidants. The oxidants investigated are Fenton's reagent, hydrogen peroxide, Oxypro, potassium permanganate and potassium persulfate.
The study was made on untreated leachate and leachate that has been treated in an aerated dam followed by sedimentation dams collected from the Hovgården landfill, and alson on sludge water from sludge storage cells.
The effects of the five oxidants have been established by analysing the UV absorbance at the wavelengths 253,7 nm and 260,0 nm at different pH values. The UV absorbance was used to indicate the amount of aromatic hydrocarbons in the water. Also analyses of iron and manganese were done after the experiments with potassium permanganate, hydrogen peroxide and Fenton's reagent.
En ny metod för intraoral röntgenundersökning på häst :
A method for equine intra oral radiology has been tested. In the study, both a digital system with an intraoral sensor connected to a laptop and a system utilizing image plates and digital developing was tested, initially on cadaver sculls and finally on sedated horses.
The digital sensor was not considered viable for this purpose, while the system with image plates and digital developing worked very well. Two different techniques, i.e. parallel and bisectris, are suggested for the best visualization of different parts of the teeth. Intra carious injections of Mixobar oesophaghus contrast fluid was found useful when evaluating the extent of carious lesions.
Compared to extra oral radiology, the new method had several advantages and can be used both in clinic and field practices..
Utveckling och validering av en LC-MS/MS metod för kvantifiering av clopidogrel och dess metabolit i plasma
Clopidogrel is an antiplatelet substance that prevents blood coagulation in the arteries. It is an inactive pro drug that becomes activated after first-pass metabolism by the liver. The active metabolite of clopidogrel is 2-oxoclopidogrel, which is unstable therefore pharmacokinetic data is obtained by measuring the inactive metabolite clopidogrel acid in plasma. Clopidogrel is taken orally in tablet form. The aim of this project was to develop a LC-MS/MS method for quantification of clopidogrel and its metabolite in plasma. The method has been developed by optimizing the sample preparation.
Fåglar i urbana miljöer : kvaliteten på urbana habitat och om beståndstäthet är ett bra mått på habitatkvalitet
The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.
Vad har Gandhi med familjeterapi att göra?
Introduction: In this study an innovative and multimodal method in family therapy called NVR, Non-Violent Resistence, is examined. NVR is an approach developed by Haim Omer, professor in psychology at the University of Tel Aviv. This approach is described as coming from the ancient ideological roots used by Gandhi in the Nonviolent resistence of oppressive regimes. NVR advocates that the parents give up the desire to control their children. Instead parents should take control of their own lives by actively resisting any behaviors of the child that are damaging.
Omega System Kalibrering: Strål X-Separation mätning och kalibrering
Micronic Laser Systems AB produces and develops machines for the photo mask production market. One of their products is the Omega machine which exposes photo masks using 5 laser beams simultaneously. It is important that the distance between the each laser beam, the x-separation, is the same. The x-separation is today measured by exposing a photo mask with a certain pattern and thereafter measured with a metrology system. This takes to much time and it is desired to find a faster method to measure the x-separation without loosing precision.The task for this master thesis is to improve an existing measurement method which uses a calibration mask.
