Alternativa Drivmedel som Enhetsdrivmedel
Fossila drivmedel står idag för en överlägsen majoritet av den totala användningen av drivmedel som dagligen förburkas. Alternativ till de fossila drivmedlen krävs för att säkerställa tillgång i framtiden. Försvarsmakten har fått uppdrag från regeringen att utforska möjligheten att övergå till att driva sina fordon på förnyelsebara bränslen.Militära organisationer strävar efter ett enhetsdrivmedel, alltså ett gemensamt drivmedel som driver samtliga fordon och enheter. Största anledningen är den förenklade logistik som kan uppnås om endast ett drivmedel används.Detta arbete har sökt efter ett alternativt drivmedel som skulle kunna användas som enhetsdrivmedel inom Försvarsmakten. Detta för att lösa problematiken med att både byta till ett förnyelsebart drivmedel och ett enhetsdrivmedel i samma fas.Slutsatserna som dragit i detta arbete är att FT-bränslen har potential att användas som enhetsdrivmedel ur ett tekniskt perspektiv.
Urban agriculture : experiences from the Swedish horticulture
Urbanisation has increased the distance between the urban and the rural. Urban agriculture can be a solution to overcome that distance. The characteristic of urban agriculture is the intensive production in intra urban and peri-urban areas. Until 1950s food production in cities was an important part of the urban economy and the urban food supply. Since the 1950s the urban located production of food has almost ceased in Sweden, partly as a result of cheap food imports.
Tillämpning av RFID i små och medelstora hamnar
Enligt Steenken et al. (2004) motsvarar container shipping 60 % av världens transporter över haven. Användningen av containertransporter har ökat med tio gånger sedan mitten av 80-talet. En ökning av containertrafik ställer enligt Steenken et al. (2004) ökat krav på hamnars logistik och styrning samt val av teknisk utrustning.
Kunskap, motivation och stöd : En studie om kompetensutveckling inom statistisk analys av experimentella stöd
Testing and analysis of measurement data is a major part of the workday for development engineers within the section Fluid and Emission Treatment to assure the quality of products developed by Scania CV. The ineluctable variation and therefore uncertainty of results can be quantified and discussed with the use of statistical methods.The overall objective of this study is to examine how the competence of development engineers can be improved within the area of statistics. This has been done by relating the concept of competence with the use of statistical methods to analyse experimental data and by investigating which factors that influence the competence of the engineers. Observations of the daily operations, interviews and a focus group with development engineers and a workshop with management personnel, has been used as research methods in this study.The results show that the desired competence, from the perspective of the individual, consists of knowledge, motivation and support. It is important that none of these parts are neglected when the competence of engineers is to be strengthened.
Virtuell design av en testrigg för ett vindkraftverks drivlina - Analys av vibrationsdynamik
This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.
Kampen mellan etablissemang och näthatare - En studie om näthatsdebatten
This essay examines the Swedish debate on Internet hate with focus on theories concerning Internet as a public sphere, sociocultural turbulence and subaltern counterpublics. Examining material fromnewspapers, alternative news media and discussion forums, with an hermeneutical influenced method, the task is to understand the Internet hate debate, and the study wishes to discover its relations to biggercontexts, such as social transformations and power dynamics. The conflict evolves between the establishment (journalists, writers, politicians et cetera) on one part, and Internet ?haters? on the other.The examined theme also shows a conflict where the two combatants show not only two opposite views on what Internet hate is, but also shows two different conceptions of the world..

Pilotstudie för att utvärdera effekten av L-Mesitran : honungsbaserad sårsalva : vid behandling av yt-pyodermi hos hund.
Green manuring is a way of creating an organic fertilizer by growing a crop that is mowed down. Besides the fertilizing effect this method has been shown to have a positive influ-ence on soil organic matter as well as weed flora, and green manure is an important me-thod of weed control in organic farming in parts of Sweden. However, the release of nu-trients from the green manure varies and can therefore be difficult to control. Risks for losses of nutrients are also present. Although the area of organic farmland is increasing in Sweden, the use of green manure is decreasing.This report contains a literature study which compiles research on the functions of green manure in a cropping system and also how the crop can be used if harvested, for example to produce biogas.
Historiska emissioner av bly och arsenik till luft från Åfors Glasbruk och deras konsekvenser för miljön.
Åfors glasswork was a company which started in 1876 and closed in 2012 due to the bad economical situation in the company. After its closure, the glasswork left behind contaminated soil with different concentrations of heavy metals such as, arsenic from arsenic trioxide, a chemical used to remove bubbles during the melting of glass, and lead oxide, a chemical used in the production of crystal glass. Crystal glass?s production occurred under 1921-1971, but emissions of lead into the air from Åfors glasswork continued until 2011, because of the artist Bertil Valliens? artglas was made in Åfors glasswork from 1970?s and onwards.The aim of this study was to estimate how much lead (Pb) and arsenic (As) that were released by Åfors Glasswork into the atmosphere during the operational period of the glasswork in comparison with how much of lead and arsenic were purchased for the company. Added to the assistance of the data from National Archives the variations in the activities of Åfors glasswork could be shown.
Komplementär och alternativ medicinska behandlingsmetoder för lindring av smärta vid artros : en litteraturstudie
BakgrundArtros, som är en degenerativ ledsjukdom, är en av de vanligaste sjukdomarna i Sverige. Sjukdomen är vanligare hos äldre än hos yngre och det är fler kvinnor än män som utvecklar artros. Normalt sker en nybildning av brosk kontinuerligt i alla kroppens leder, men vid artros bryts brosket ner utan att någon nybildning sker. Artros kan förekomma i alla kroppens leder, men det är framför allt knä, höft och fingerleder som drabbas.Smärta är oftast det första symtomet på sjukdomen. Smärtan behandlas i första hand med paracetamol eller non steroid inflammatory drugs (NSAID).
Variationer- En intervjustudie om sexualitet och uppfattningen av det normala
Can the need for inclusion result in certain social norms remain unchallenged, and over time become hard to identify? To ?fit in? and be accepted in different social contexts we have to behave according to the dominating rules and conventions. We accept characteristics and make use of attributes specific for the group we want to be a part of. When we accept these attributes we contribute to keep the concept of them alive. Further on these attributes will be picked up by the next person who wants to become a part of that specific context.

From wheels to walking : exploring an alternative planning approach in Sub-Saharan countries - the case of the Axis in Nairobi, Kenya
Rapid urbanisation is putting strains on both the landscape and the city dwellers and the pressure on planning for sustainable and equitable cities is crucial. As many cities in Sub-Saharan Africa are expanding, city planning has trouble keeping up to meet the needs of the growing amount of urban dwellers. Many cities have also been planned with the cars in focus and the needs and comfort of the pedestrians have been overlooked. The capacity of institutions is limited due to centralized government and bureaucracy, as well as corruption. Planning is erratically implemented and it is difficult to know what will happen.
