Biblioteks- och informationsvetenskapens överordnade identitet : ämnets betydelse för studentens yrkesinriktning
Library and information science (LIS), being a research area characterized by theoretical discord and definition disarray, provides an interesting field of inquiry. Its content, boundaries, scope and superior identity are not clearly stated. This Master s thesis focuses on a thus far unexplored perspective on the discipline: a conceivable statistic and causes- and- effect relationship between the LIS students appreciated identification with the superior identity of the discipline, and the chosen vocational direction within the field. This relationship is examined through testing a working hypothesis on the results of a major quantitative questionnaire survey. The theory behind our research derives mainly from Thomas Kuhn and Richard Whitley.

Planering av produktionsflöden. Vad kan påverkas i projekteringsfasen?
Göteborg Energi AB är ett bolag med höga ambitioner att säkerställa ett stabilt distributionsnät för sina kunder. Med ett säkerställande följer åtgärder i form av beräkningar för komponenter som transformatorer av olika märkeffekt, hög- och lågspänningssäkringar och andra kritiska skyddsanordningar som t.ex. reläskydd. Vid ett flertal tillfällen under de senaste åren har det uppmärksammats en problematik där ett fel i lågspänningsnätet har löst ut anslutande transformator. Felet har grundat sig en svag selektivitet mellan transformatorsäkring och lågspänningssäkring.

Klassning av fjällbjörkskog enligt FAO:s definition av skogsmark med hjälp av flygburen laserskanning
Sweden?s forestry legislation was updated in 2010 and a new definition of forest land was introduced. This definition was adapted to the one used by the Food and Agriculture Organization of the United Nations (FAO) for international statistics on the state of the world's forests. It is in short based on the lands ability to grow forest that reaches 5 meters, 10 % canopy closure and has a continuous distribution, according to FAO at least 0.5 hectares. A country-wide laser scanning is now carried out for the production of a new national elevation model; the laser data also provides information on forest height and density.
Studier av koppar i mjölk : en prooxidant med negativa effekter på mjölkkvaliteten
The taste of the dairy product is probably the main factor determining consumer?s dairy products choice. Consequently it is of great importance that the product tastes good and as expected every time. Off-flavors in milk can be caused by for example oxidation of the milk fat. Since copper is a prooxidant, a high copper content in the milk can cause oxidation.
Jämförelse mellan ?Auditory Brainstem Response (ABR) och ?Auditory Steady State Response? (ASSR) för att uppskatta hörtrösklar på barn i narkos. Kan testtiden minska om 500 Hz utesluts vid ASSR-mätning?
ObjectiveThe objective of this study was to investigate the clinical application to use ASSR in anesthetized childrenDesignOne main ambition of the investigation was to compare hearing threshold using ABR with estimated hearing threshold using ASSR. Another aim was to examine if the duration of an ASSR measurement could be reduced by only using the frequencies 1, 2 and 4 kHz and exclude the frequency 0.5 kHz. This is a retrospective study using electrophysiological measurement from a database.ResultResults showed a high correlation between hearing threshold using ABR and estimated thresholds using ASSR, with the frequency 0.5 kHz showing a slightly lower correlation. Result also showed that the test duration was increased when using all test frequencies in ASSR-measurement compared to when 0.5kHz was excluded. ConclusionThe study showed a high correlation when comparing hearing threshold using ABR and ASSR.
Den ständigt avvikande förorten : Medias diskriminering av förorten Andersberg
The emerging Swedish suburbs of the 1960- 1970s started out as a utopian vision: a new city for the modern people. Media presented a different view and emphasized the inhuman livingenvironment and the social problems of the suburbs. Nationwide there have been local attempts to avoid this negative publicity by adjusting identified suburban problems. Due to medial presentation the suburbs are still associated with segregation, criminality and social problems. The presentation of suburbs and immigrants affects not only the process of integration and the general public idea of integration processes, but also the individual perception of themselves and their living.
Utveckling i Ammerån : att skapa ett hållbart fiske med hög kvalitet
Ammerån which is a small forest river in eastern Jämtland is a well-known river that has been a popular fishing river for a long time. The actual Ammerån begins downstream the lake Solbergsvattnet at Hammerdal and flows into the Indalsälven 10 km upstream Hammarstrand. The river environment switches between forests with wilderness feeling and open agricultural land. The entire Ammerån is today a nature reserve and protected from hydropower development. Fishing in Ammerån has mainly been focused on trout and grayling, and is so even today.

This master of science thesis is focusing on how the fault handling on hardware connected toa control unit on a Scania vehicle is working. To the hardware counts buttons levers, sensorsand CAN. The work has been concentrated upon how the fault handling is working and if it ispossible to find any new fault modes.The control unit that has been studied is called the Coordinator and is the core in Scanias threenetworks of control units. The Coordinators work is to transmit messages between the threenetworks and to process signals from buttons, levers and sensors. The values is then usedinternally or is sent to other control units on the CAN networks.
Används både formativ och summativ utvärdering i ett projekt?
In companies today, it is becoming more and more common for employees to work in a project based environment, as a result many companies have developed their own project models. Companies with a well developed product culture are striving to improve their existing models, and businesses relatively new in the marketplace are aiming to reach a high level of maturity as well as reach high levels of efficiency in the shortest time possible. As the number of mature and efficient companies with well developed project model increase, so does the level of competition in the market. Since a well developed project model often leads to a more efficient and accurate way of carrying out the project, which in turn leads to shorter delivery time towards the client. This is crucial as time is one of the most valuable parameters of competition in today?s business environment.
Effekter av olika skiftformer : En studie om effekter av olika skiftformer inom räddningstjänsten
Bakgrund: Uppsatsen tar upp problematiken kring att organisera arbetstid inom räddningstjänst. Grundförutsättningarna är att räddningstjänst är en High Reliability Organisation (HRO) och att det påverkar organisationen. I och med New Public Management (NPM) framfart och den ekonomiska situationen i världen har räddningstjänsten fått ett ökat krav på kostnadsbesparingar och resursutnyttjande. Då personalkostnader står för en stor del av räddningstjänstens kostnader kan förändringar av brandmännens arbetstid och skiftgång vara ett logiskt steg, något som skett i Greater Manchester Fire and Rescue Service (GMFRS).Syfte: Syftet med uppsatsen är ett ge ett teoretiskt bidrag till hur NPM influerade reformer påverkar en HRO. För att göra detta frågar vi oss vad de olika skiftformerna får för konsekvenser för de anställda och organisationen.Metod: Uppsatsen har en kvalitativ forskningsansats vid studerandet av fallorganisationen Greater Manchester Fire and Rescue Service och Storstockholms Brandförsvar.
Biochar as soil amendment in flow-through planters - for increased treatment of zinc roof runoff
In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.
Härliga hagar och skrämmande skogar : om våra känslor för landskapet och vad de beror på
Do our imaginations of real landscapes get affected by works of art such as paintings, myths and literature? They often give very colourful descriptions in words as well as pictures. Do they actually change our feelings for the landscapes we are in and carry around as images inside?
Close your eyes and take a few deep breaths. Imagine that you are leaning against a wooden fence a mild summer evening.
