Fjärrlåneverksamheten på Borås och Kalmar högskolebibliotek
The object of this essay has been to investigate the interlibrary loan service at the universitylibraries of Borås and Kalmar. For this purpose a quantitative and a qualitative methodhave been used.The main body of information consists of statistic data concerning the incoming interlendingorders for a three-month-period. In order to examine the circumstances under which theinterlending activity exists several interviews were made.The study showed that there are several important factors which together make up the complexitythat governs the interlending activity. What type of demand there is depends on theeducational level, whether the different study programmes have a broad or limited subjectorientation or not, and if the demand is of a constant or an inconstant nature. Well-establishedroutines at the information-desk and co-operation with the departments of the different studyprogrammes are important factors in keeping the knowledge of what books and serials areneeded up to date..
Prognostisering av försäkringsärenden : Hur brytpunktsdetektion och effekter av historiska lag? och villkorsförändringar kan användas i utvecklingen av prognosarbete
I denna rapport presenteras ett tillvägagångssätt för att hitta och datera brytpunkter i tidsserier. En brytpunkt definieras av det datum då det skett en stor nivåförändring i tidsserien. Det presenteras även en strategi för att skatta effekten av daterade brytpunkter. Genom att analysera tidsserier över AFA Försäkrings ärendeinflöde visar det sig att brytpunkter i tidsserien sammanfaller med exogena händelser som kan ha orsakat dessa brytpunkter, till exempel villkors- eller lagförändringar inom försäkringsbranschen. Rapporten visar att det genom ett metodiskt angreppssätt går att skatta effekten av en exogen händelse.
Peltierelement - spillvärme till el : Peltier element - waste heat into electricity
The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.
Occurrence of Verotoxin-encoding phages in mussels grown downstream the sewage treatment plant in Lysekil
The purpose of this study was to investigate the occurrence of Verotoxin-encoding bacteriophages in mussels, cultured downstream the sewage treatment plant in Lysekil.Mussels were collected in three growing areas from April 2008 to March 2009. Real-time PCR was performed for detection of vtx1 and vtx2 genes and enrichment of bacteriophages on non Verotoxin-producing Escherichia coli O157: H7 was carried out. All samples in real-time PCR analysis were negative; no presence of Verotoxin-encoding phages was shown. No plaque was formed on blood agar base plates, indicating that no bacteriophages had been taken up by E. coli bacteriaThe levels of Verotoxin-encoding phages and E.coli outside the sewage treatment plant in Lysekil were not high enough to be able to form VTEC in mussels, indicating that the faecal contamination was low.
Detection of Honey Bee Viruses in Apis mellifera and Apis cerana
Two species of bees in the genus Apis, real honey bees, has long been of interest for man. These two are the European honey bee, Apis mellifera, and the Asian honey bee, Apis cerana. In Vietnam, beekeeping is of great importance, both with A.cerana and A.mellifera. The aim of this project was to investigate if the introduction of the European honey bee in Asia has affected the Asian honey bee, and whether different pathogens from A.mellifera have been transferred to A.cerana. Totally 40 samples, 20 from every species, were analysed for 8 different viruses.
Bristfällig tillbudsrapportering : En sammanställning av attityder och kunskap kring tillbud inom Peab
The construction industry stands as one of the industries in Sweden where most employees tend to encounter accidents. At the same time, the Swedish authority of work environment estimates that there are large numbers of hidden statistics with accidents and incidents that never gets reported. To prevent accidents, the Swedish authority of work environment has decided that every company have to, beside report every accident and major incident to the authority of work environment, keep statistics and evaluate every incident that happens at their places of work.The people responsible for work environment at the Swedish building contractor Peab, believe that it is only a fraction of all incidents happening at their construction sites that actually gets reported. The purpose of this study is to investigate the reason why employees of Peab do not report incidents. By an inquiry and interviews with both craftsmen and office holders at Peab Bygg Öst 1, the employees? attitudes and knowledge have been studied and evaluated.The study shows that the craftsmen´s knowledge of incidents is relatively low.
Cytokinuttryck vid vaccination med olika vaccinkoncept mot FIP :
Feline infectious peritonitis (FIP) is a feline viral disease with high mortality. There is no cure or any effective vaccine available today. Many questions are yet to be answered about this disease and the immune response in affected cats.
The aim of the study is to evaluate two different techniques for the study of cytokine profiles in cats vaccinated with a vaccine concept against FIPV. More information about the immune response in these cats could give valuable information to better understand the pathogenesis of the disease and the development of an effective vaccine.
Mätning av partikelmassa i avgaser från en dieselmotor
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.
DEN TILLHÖRIGHETSSKAPANDE MÖTESPLATSEN - Folkbiblioteket som mötesplats i svensk biblioteksdebatt
This Master's thesis concerns the public library as a public meeting place. Our aim has been to find out why and how the library as a social meeting place has been discussed within the Swedish library community and if there has been a constant core in the discussions from the mid 70's and up to the present day. In order to do this we apply a place and space-perspective. The result of the study is that the core of the said discussions concerning the library as a meeting place is to create belongingness. This is the reason why the library community has an interest in the public library's function as a meeting place with the idea that people, by using the public library in that aspect, may experience a feeling of belonging to the society.
Våld eller sex? - En litteraturstudie om den akademiska kontroversen kring våldtäkt
Partly due to its consequences on the physical and mental health but also because of women?s constant fear of being violated, rape is considered to be a public health issue. The theoretical aspects of rape were first discussed in the 1970?s mainly from the viewpoints of Susan Brownmiller and Michel Foucault. The aim of this literature study is to investigate the different perspectives on whether rape should be viewed as sex or violence, how the controversy has developed and what the authors claim that the different perspectives result in.
Karaktärisering av hästerns gångarter med accelerometerteknik
In today?s horse keeping, there is an increasing awareness of the importance of movement and activity for the horses comfort and tenability, while tradition has it that horses should be kept in boxes and small paddocks. In order to develop housing systems that fulfils and optimizes the horses needs regarding movement and activity, we need to know more about factors that influence the activity patterns of horses. A first step is to be able to record and analyze the gaits in horses with an automated system. This could be done by use of accelerometer data.In this pilot study, existing accelerometer technique was used to characterize the different gaits in horses (walk, trot and canter) by studying how their respective signal patterns differ and how this is influenced by the size of the horse.The accelerometers being used in this study measures the movement in three different spaces; horizontal, lateral and vertical.
Lågkonjunkturens påverkan på den svenska konsumentmarknadsföringen
The purpose of this essay is to analyze and understand the effects that a recession can have on a company?s marketing department. In times of a recession most companies have less means to promote their products to their target market and to build their brand. This means that cutting the marketing budget will show some effects on today?s way of marketing.
Konflikthantering ur ett genusperspektiv : Hanterar kvinnor och män konflikter på olika sätt i olika situationer?
This study examines if men and women have different conflict resolution styles in different situations. There are several studies in this area, but the results are contradictive and they don?t take consideration to the context. The study is an explorative, quantitative examine in the form of a self-report questionnaire, where different scenarios are described. These scenarios are based on the parts of the context that this study focuses on; the relationship to the other part, the perception of treatment and the place where the conflict occurs.
Evaluation of specificity of a walnut antiserum and detection of English walnut (Juglans regia) in food with ELISA and Real-Time PCR
Nuts of all kinds are common ingredients in food. For nut allergy sufferers the frequent use of nuts cause problems and "hidden" nuts in food products may elicit allergic reaction when such foods are consumed. Methods for detecting and quantifying walnut (and other nuts) with high sensitivity and specificity are therefore very important.The objective of this project was to verify the specificity of a rabbit antiserum against walnut with immunodiffusion and to determine the size of the dominant walnut antigens with Western blotting. In addition, a commercial sandwich ELISA for walnut quantification was validated and compared with a qualitative real-time PCR.The rabbit antiserum proved to be less specific but after absorption with cross-reacting nuts and seeds it showed high specificity. The ELISA kit reacted, except for walnut, with pecan and slightly with other nuts and seeds tested.
Ett Fängelselikt Samhälle...? : en diskursiv betraktelse
My essay is fundamentally about an idea. It could even be placed in the study of the history of ideas by the fact that it could be seen as if I am trying to reflect upon how one single idea can get a strong societal and historical impact. How thoughts, visions and then inventions are constructing societies and everything that derives from them. In my text I try to illuminate and connect social theory to our social reality and by using discourse (theory) analysis I try to study central terms in the discourse of surveillance. The question which is of social psychological interest would be that of how the individual in dialectical relation to thesurrounding society is free and how he then would get inflected by this surveillance.
