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.

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.

Leder kastrering av hanhundar till bättre djurvälfärd?

Castration of dogs holds many reasons and opinions, therefore methods, traditions and rea-sons vary. The approaches have during time changed from mostly surgical castrations to also including hormonal treatments. Castration is used to control the dog's reproductive abilities, for medical reasons and to possibly rectify problems of behavioral nature. How common a particular method of castration is in a country is highly dependent on the country's traditions. In Sweden it is most common with castration for medical reasons, such as possible elimina-tion of diseases, for example, benign colorectal tumors.

Påverkan av probiotika på kariesbildande bakterier in vivo

Abstract Cavities used to be a very common problem but over time humans have learned to take care of their teeth. However, there are still many who have problems. This problem is due to microorganisms and in particular the various streptococci and lactobacilli producing acids which loosens up the enamel on teeth. These bacteria can be found at various places in the mouth and saliva. Besides being a discomfort it can be a major problems and the damaged tooth needs to be removed or make a dental filling. The aim of the study was to see how intake of probiotic tablets containing Lactobacillus reuteri PTA ATCC 5289 and Lactobacillus reuteri DSM 17938 affects the levels of oral Streptococcus mutans and lactobacilli over a three-week period.

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.

AbstractThe purpose of this article was to examine how students learn French by integrating a multimode way of learning through literature, music, poetry, painting, reading, writing and IT in the classroom, in order to create understanding and motivation regarding the subject, but also a sense of cooperation and sensibility toward each one of the students Individual work. In the study of Victor Hugo?s novel Les Misérables as a tool for learning and deepen understanding about human values, the focus was laid on essentials questions such as the question of good and evil which is the major theme presented in the novel. The results showed that the students developed a vast interest in literature and human condition and made progress in French in both oral and written work but also acquired more knowledge about the French history..

Att offentliggöra döden. Vad påverkar utformningen av dödsannonser?

Since long time ago people have announced in one way or another when one of the membersof their family had died. In the old times ?oral? messages were used, e.g. people went to theirneighbors and told them what had happened. In church the priest announced the death of amember of the parish from the pulpit.When newspapers came into use at the end of 1800 and announcements became customary,this eventually turned out to be the ?proper? way in Sweden for announcing death.

Två metoder för internrevision: fallstudie på ett svenskt kärnkraftverk

Internrevisioner är ett krav om företag och organisationer är certifierade enligt ISO 9001 eller ISO 14001. Främsta syftet med internrevisioner är enligt Wahlman (2004) att bekräfta att ledningssystemet och de arbetssätt som beskrivs i ledningssystemen ger den önskade effekten. Examensarbetets omfattning är att beskriva och jämföra de två olika metoderna för internrevisioner som finns inom kärnkraftsbranschen. Dessutom ges konkreta förbättringsförslag för de olika internrevisionsmetoderna. De två olika metoderna för internrevisioner har författaren studerat på fallföretaget Ringhals AB som är ett kärnkraftverk.
