Säkerhetsaspekter vid laddning av elfordon innehållande litium-jonackumulatorer: beskrivning av risker samt en studie av kontrollerande regelverk
Fortum har i samarbete med Stockholms stad presenterat en gemensam vision för att göra Stockholm till en av världens främsta miljöbilsstäder till 2030. Ett viktigt led i detta mål är introduktionen av nya elfordon innehållande litium?jontekniken på den svenska bilmarknaden. Då det befintliga regelverket angående laddning av ackumulatorer i fordon inte nämner den nya tekniken har frågeställningen kring luckor i lagstiftningen lyfts fram av Fortum. Det övergripande syftet med studien har varit att undersöka risker och regelverk kring laddning av elbilar innehållande litium?jonackumulatorer.
Engergieffektivt Bostadsområde : Förstudie Till Aktivhusområde i Halmstad
In the thesis we have shown that it is possible with current technology, to buildneighborhoods that are largely self-sufficient. We have obtained some information aboutongoing work in the field of energy efficient buildings and active house which we have usedto develop a model. The feasibility study for Ranagård we have e.g been forced tofollow laws on groundwater covered, resulting in the construction of basements for singlefamilyhome is not possible. The model that we have built up overtime has been the central part of the work. The model illustrates very well what an activehouse neighborhood means and potential of such an area.
Två presentationstekniker för grafer : deras styrkor respektive svagheter inom en bioinformatisk kontext
This degree project has been carried out in cooperation with Enertech AB in Ljungby and is pilot study to automating all current manual soldering. The soldering process accounts for a large part of the processing cost in the production of a heat pump. The process is also a quality risk and has a major impact on the lifetime of the final product.The Main task of this project has been to evaluate automation of the soldering process, to develop automation solutions and a principle layout, to draw the design changes required for the automation and to calculate the supposed solution.This pilot study has resulted in a suggested automation solution using laser as a heat source for soldering. Calculations of the solution show that a automating a laser soldering cell is very profitable..
Ideellt kårengagemang - Drivkrafter och resultat
The purpose of this study was to examine how modern information and communication technology influence collective action within the framework of social movements. By studying the protests in the Arab World 2011, and focusing on the social movements in Suleimanya in northern Iraq, by observation taken on place, the essay discusses that collective action is closely related to the use of technology, for example cell phones and Internet.Result shows that modern communication technology has enabled immeasurable access andconnection between individuals throughout the world, which seems to be different from previouscollective action. The new communication channels in the form of social media, has been used for the dissemination of information and news, documentation, organization and membership recruitment in the social movements in the Arab World and Suleimanya. The new social movements have the tendency to be decentralized and flattened organized, they are now self-organizing and that they only do a whole as global patterns, as evidenced by the social movements in the Arab World andSuleimanya..
Solceller som energikälla och solskydd för tält
This degree project is an investigation of solar cells and their ability to deliver electric power as well as reducing the need for cooling. The main object of interest is a BASE-X shelter. The shelter is purchased by the Swedish Defence Materiel Administration, FMV to be used for command and camp in the new force called Nordic Battlegroup, NBG. The demand on the equipment is firstly that it should have a small weight to be easy to transport and handle and secondly to be easy to bring up fast. Therefore the choice of solar cell technology fell on thin film cells.
Effekten av arktiskt klimat på inre kvalitet hos bär
This project is a literature study with the hypothesis that Arctic climate has a positive effect on the accumulation of metabolites in berries. Plant metabolites are often divided into primary and secondary metabolites. Primary metabolites such as proteins and nucleic acids are essential for cell function, while secondary metabolites are often non-essential, but have important functions regarding reproduction and survival. The berries mentioned in this project are from the families Ericaceae, Rosaceae, Elaeagnaceae och Grossulariaceae.The conclusion drawn from this literature study is that it is not obvious what favours accumulation of metabolites in berries. Other factors aside from climate affect the production of secondary metabolites, such as time of harvest, cultivars and ripeness.
Effect of insulin during oocyte maturation in vitro on bovine early embryo development : partially evaluated by novel fluorescent staining
Fertility is of central interest in the dairy production but has during the last decades declined. Increased milk yield has resulted in high pressure on the metabolism of the dairy cows that are supposed to manage the transition from dry cows to lactating cows within a few weeks around the parturition. Much indicate that metabolism and fertility are closely linked, with insulin playing a substantial part. There are many studies suggesting that the main part of gestation loss can be found during the early embryo development, a period which can be studied in vitro. The aim of this study was to test the effect of insulin during maturation in vitro and to evaluate two different fluorescent stainings on oocytes and embryos; a nuclear stain and a staining of apoptotic cells through the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)-method.
Bovine cumulus-oocyte-complexes (n=991) were aspirated from abattoir-derived ovaries.
Marknadsföringsprodukt för Kiruna studentkommun
This report is the concluding part of the course national minorities, main focus on design, at Luleå University of Technology spring 2007. The purpose of this written examination is to produce a prototype to a product, which can be used both when marketing Kiruna as a student municipality and when recruiting students to the study programmes Kiruna offers. The product has been produced through systematic problem solving, where methods to fix the problem, gather facts, examine and come to a solution have been used. The product should in one way or another get the student to think of Kiruna as a student municipality and it should also appeal to the target group ? the students.

Juverinfektion hos tackor med kliniskt friska juver : bakterieförekomst och celltal i mjölk
Subklinisk mastit (juverinflammation utan synliga symtom) är vanligt hos flera mjölkproducerande arter inklusive får. I kött- och pälsfårbesättningar kan subklinisk mastit ge lägre slaktvikt hos lammen till följd av minskad mjölkproduktion hos tackan. Risken att lammen försöker dia en annan tacka ökar om de inte blir mätta av sin mammas mjölk. Eftersom de flesta mastiter är bakteriellt orsakade kan lammens tjuvdiande vara en potentiell smittväg för juverinfektioner. För att förhindra smittspridning behövs snabba och pålitliga fältmetoder för att detektera juverinfektion.
Syftet med studien var att kartlägga förekomsten av juverinfektioner hos tackor med kliniskt friska juver i svenska kött- och pälsfårbesättningar.
Finns det ett samband mellan ökad mjölkproduktion och mastit?
The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

The work has been carried out in cooperation with the company Zenit Design in Malmö. The project's goal was to restore, improve and produce an ozone generator. During the project, the authors sought relevant literature in databases, been in contact with US suppliers of fuel cell membranes, Asian suppliers for the processing of Teflon and Titanium parts in mechanical engineering and Swedish suppliers of various standard components. The authors had access to a temporary lab at Zenit and electron microscope at Halmstad University where material tests were performed. The authors have also had access to measurement equipment to measure amounts of ozone.During the work, the authors have mapped how an existing ozone generator works and then have their own development.
Utveckling och tillämpning av en GIS-baserad hydrologisk modell
A distributed hydrological rainfall-runoff model has been developed using a GIS integrated with a dynamic programming module (PCRaster). The model has been developed within the framework of the EU-project TWINBAS at IVL Swedish Environmental Research Institute, and is intended for use in WATSHMAN ? a tool for watershed management developed at IVL. The model simulates runoff from a catchment based on daily mean values of temperature and precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model.
