Partnering för bättre samarbete men till vilket pris? : En studie av offentlig beställares argument till partnering

The electric vehicle market has potential to contribute to Sweden?s national goal to have a fossil fuel independent transport sector by 2030. However, the market answers to a lot of challenges making it difficult for the market to fully reach its potential. The volume of electric vehicles has seen a steady increase during the last year (2012), although many of these vehicles are mostly for PR purposes or bought by the public sector that wants to lead by example. Still, barriers in the form of high purchase costs, an anxiety for the limited battery capacity and the lack of standardisation are some of the problems that the market is struggling to solve.

Registreringsmetoder för initial och avancerad dental erosion : Litteraturstudie

Introduktion: Dental erosion definieras som förlust av tandens hårdvävnad genom en kemisk process som inte involverar bakterier. Dagens förändrade livsstil och kosthållning medför att våra tänder oftare utsätts för kemisk påverkan som kan leda till erosion. Det är flera faktorer som samverkar och dental erosion har en multifaktoriell etiologi.Syfte: Syftet är att beskriva olika registreringsmetoder för dental erosion.Frågeställningar: Vilka metoder kan användas för registrering av initial erosion? Vilka metoder kan användas för registrering av avancerad erosionsskada? Vilka metoder är kliniskt beprövade på patient?Metod: LitteraturstudieResultat: Ett flertal registreringsmetoder fanns beskrivna i litteraturen, merparten var inte applicerbara kliniskt. Registeringsmetoderna som framgick i den beskrivande litteraturstudien var: 3D scanning microscope (IFM), Atomic absorption spectroscopy (AAS), Digital photography (DP), Focus-variation 3D microscopy (FVM), Longitudinal microradiography (LMR), Non-contact confocal laser scanning microscopy (CLSM), Optical assessment, Optical profilometry (OP), Quantitative light-induced fluorescence (QLF), Scanning electron microscopy (SEM), Stylus profilometry (SP), Ultrasound, White light interferometry (WLI) och X-ray diffraction (XRD).Konklusion: Vid registrering av initial erosion krävs analys av tandytans mineralinnehåll samt optiska analyser med hjälp av instrument.

Konstitutionsutskottet och Regeringskontrollen - En studie av kontrollmaktens utövande i enkammarriksdagen 1971-2007

The purpose of this study is to examine how parliament executes its responsibility of oversight against the government. In Sweden, parliamentary oversight of the government rests with a standing committee of parliament known as the constitutional committee.Drawing on general principal-agent theory I construct a model in which members of the constitutional committee are seen as agents in double and conflicting agency assignments. This constitutes a problem for the agent. Since it is the party group in parliament that controls the fulfilment of the agents? objectives, the agent is presumed to follow the party assignment to the detriment of the parliament assignment.The model generates two hypotheses concerning they type of oversight we should expect the members of the constitutional committee to perform against the government.

Zoonoser hos sällskapsdjur : en risk för immunsupprimerade personer

Our companion animals can, with or without symptoms, carry infectious agents which have a potential to induce diseases in man, so called zoonoses. An immune compromised person has an increased risk of becoming infected by various agents, and thus also has an increased risk to become infected by one?s own companion animals. A study was carried out within the veterinary program at SLU, Sweden, based on a questionnaire answered by 31 physicians, 31 veterinarians and interviews of 30 immune compromised persons in Sweden. The study investigated the following questions: Which zoonoses do physicians and veterinarians consider to be the most important to inform immunecompromised persons about? How are immunecompromised persons being informed by their physicians about the risk of catching zoonoses from their companion animals? How are the owners of zoonosis-infected animals being informed by their veterinarians about zoonoses? Does veterinary medicine and human medicine communicate about zoonoses, in order to take the best care of immunecompromised persons in contact with animals? The results of our study imply that: - Physicians and veterinarians differ about which zoonoses immunecompromised persons should be informed about. - Only oral information is passed to immunecompromised persons and animal owners.

I förändringens spår En undersökning av referensbibliotekariers accepterande av tillgängliggörandet och användandet av databaser på och via folkbibliotek

In Sweden most public libraries give users access to databases. These databases are sometimes possible to reach outside the library by internet at any time and this provides a change for the library and the society. Librarians function as change agents when they give access to databases and when databases are introduced to users. However, reports show that the use of databases, especially those in English, is not high in reference work. This study aims at analysing attitudes of librarians to access and use of databases on and by public libraries.

Trombocyträkning hos katt : en ny metod

Platelet aggregation is a major and common problem in blood samples from cats. This greatly affects the accuracy of counting of the platelets. Because of the difficulties in counting feline platelets, results for patients and reliable reference values for cat platelets are currently so inaccurate as to be almost useless in diagnosis of thrombocytopenia. In this study we used an effective method to prevent platelet aggregation. Blood was collected in CTAD test tubes and prostaglandin E1 was added to the blood sample.

En praktisk lösning - om styrningsteknologier inom könsutredningar

The purpose of this article is to explore the technologies of government that are created within gender disorder assessments as an institution. I have done so by utilizing Norman Faircloughs discourse analysing instrument ?communicative action?, which focus on the social institution as relational.The material is strategically chosen by gathering texts from the Swedish state, the psychiatric clinics, NGO:s and by performing interviews with transsexual patients.When analysing the communication of the main agents, I have concluded that practices highly are a result of repeating text and speech inside the institution. The psychiatric assessments can also be seen as an illustration in changes in how citizens are governed in advanced liberal societies, where the role of the state has been gradually reduced in favour of other agents.I consider that the change illustrates an ?acting at a distance?-mentality where the patient is introduced to participate in the definition of the care in what I call ?negotiation as a technology?.

Dåliga mäklare, eller bristande kunskap hos konsumenten?

Aim: The aim of this thesis is to through a survey, gain information about the tenant owners knowledge concerning their own and the real estate agents rights and obligations, this to elucidate one of the factors we think play a big part in the general publics dissatisfaction about the real estate agents and the negative picture painted of them in media today. By throwing light on the assumed lack of knowledge in this area we hope to contribute to improve the information communicated to the customers so that they can feel safer when consulting a real estate agent in this matter.Our main question in this thesis is: How much knowledge does tenant owners and tenant owners to be have concerning the division of responsibilities when it comes to selling and buying a tenant owned flat and what problems can the presumed lack of knowledge in this area lead to?Method: We have used a combination of qualitative and quantitative methods. Data has been collected through a survey which we have put together and analyzed both based on the results we got from the survey but also based on the reactions we received from the participants. The results are presented both in text and in diagrams.Result & Conclusions: The results we got from the survey indicate that the knowledge among our participants is much worse than what would be desired.

Sveplaserns användning till inventering/befästning/kontroll av vägmarkering

The thesis mission is to investigate whether the swiveling laser that Vectura (former Vägverket Konsult) has in use to measure the road areas and straddle measuring can be used to detect differences in the reflective road markings function. This is to increase use of the swiveling laser and get rid of the manual measurements performed today.Currently, the measurement of road markings reflective function is performed with both mobile and handheld measuring instruments. The purpose of this thesis is to develop better methods for determination of road markings? reflective function, in order to facilitate the description and suggestions for improvements of the maintenance of road markings reflective function.The questions that the thesis has been to start with are:Can the swiveling laser detect differences in longitudinal and transverse road markings reflective function?The accuracy of measurement has been sweeping the laser over the reference instrument (LTL-2000)Is it necessary with a conversion factor for swiveling laser data against the reference instrument data?To answer the question 2 and 3, there has been a field work in Värnamo where a road stretch with longitudinal road markings and zebra crossing (transverse road markings) has been investigated with a swiveling laser and LTL-2000.The formulas and calculations contained in the thesis are drawn from scientific reports that are produced by VTI in Linköping. The same formula that was used to calculate the optical measurement data was also used for the swiveling laser data.

Värdepåverkande faktorer för bostadsrätter i småstäder i Sverige : Value-influencing factors for cooperative flats in small towns in Sweden

There are various value-influencing factors that have various effects on the value of a cooperative flat for buyers. What generates value is individual and different from buyer to buyer, but also between buyers and real-estate agents. Consequently, the real-estate agents who perform valuations can make incorrect estimates of a residential value. Therefore, it is important to examine which factors are important for buyers to prevent incorrect valuations. To find out which these factors are and which of them that are the most important for potential buyers, previous research has been done in larger cities in both Sweden and other countries.

Effektivt nyttjande av högeffektslysdioder i mobil belysning

The purpose of this master thesis has been to find different solutions to the design of a headlamp with a cluster of three or possibly four high power LEDs (Light Emitting Diodes). During the work, two different problems have been considered; how to design a lens in order to shape the light beam in a desirable way, and how to design a cooling system which will lower the temperature of the LEDs as efficiently as possible, still taking into account the geometry set by the optical solution as well as other given geometries. The results presented in this thesis are partly the outcome of a literature study, but derive mainly from a number of tests and measurements made on two test rigs and one concept prototype..

?Barnbibliotekarier är rätt kaxiga!?: några svenska barnbibliotekariers arbetssituation idag analyserade utifrån Pierre Bourdieus begrepp.

The purpose of this master thesis is to investigate how some children's librarians view their working situation. There is one main question and three subquestions at issue: How is the working situation of the children's librarians today described by agents on the library field? - Are children's librarians ascribed any value and has this changed during the last three decades'? - What is the apprehension of children's librarians and what qualities should they possess? - What is considered to be most important about work of children's librarians'? The thesis is based on qualitative interviews with children's librarians, library managers and library consultants. The interviews are analysed by the help of Pierre Bourdieu theoretical concepts; capital, habitus, field, doxa and distinction. Today, children's librarians are ascribed capital by their librarian colleagues because of their specialist qualifications.

Hur ser börsnoterade fastighetsbolag på vakans : En undersökning av den kommersiellafastighetsmarknaden

The commercial real estate market makes up a large part of Sweden's property portfolio, as well as other open, free markets in the real estate market it is regulated by supply and demand. There are several factors that affect the supply and demand in the commercial real estate market, for instance the price, type of real estate and the condition of the real estate. In order to achieve success in the commercial real estate market it requires that real estate agents have a certain expertise and flexibility in their thinking to adapt commercial real estates to supply and demand. Active investors on the commercial real estate market are for instance private real estate agents, their knowledge and experience will help increase the value of commercial real estate in the long run. In order to provide the market flexibility in its real estate portfolio, vacancy is a factor that can be used.

Läkemedel som förebygger och behandlar trombos hos hund och katt

Several diseases increase the risk of thrombosis in dogs and cats, often with a fatal outcome. Currently there are no definite treatment guidelines for the use of thrombolytic and thromboprofylactic agents in veterinary medicine. None of these drugs are approved for dogs and cats in Sweden. Medicines aimed for humans have been used tentatively. This literature study is an investigation of what is currently known about the effects and safety of these pharmacological agents when used for dogs and cats.
