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.

Upproren i Arabvärlden. En studie i kommunikationskanalernas roll i kollektiv handling
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..
Levo : En lyftanordning för höjdjustering av manuella gåbarrar
The parallel bars is used in physical therapy and is mainly used for patients who have to train walking and balance after a stroke or an operation. It consists of two long handrails with two legs on each handrail. These legs go down into two ground-plates and are locked at the wanted height with a pin. The parallel bars is an appreciated device and is used on a daily basis in many care units.The main issue with the manual parallel bars is that it is very difficult and heavy for a single person to adjust the height of it. If a larger adjustment of the height has to be done, the legs have to be adjusted one at a time otherwise the they will be locked.

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.
En jämförande undersökning om förloppet vid terapeutiskt utförd KAT-töjning och statisk egentöjning: Single Subject Experimental Design
Bakgrund: En stram muskel kan orsaka ett försämrat rörelsemönster som i sin tur kan vara orsaken till skada, detta kan dock motverkas genom stretching (töjning). Syfte: Syftet med studien var att undersöka hur och om rörelseökning i hamstringsmuskulaturen skedde genom töjning med KAT-metoden respektive statisk töjning under en töjningsperiod på tre veckor. Metod: Förloppet kring stretching av hamstringsmuskulaturen undersöktes genom töjning varannan dag under 10 interventionstillfällen. Studien genomfördes som en Single-Subject Experimental Design (SSED). Baseline och withdrawalmätningar grundlades där inga töjningar utfördes.
Konstruktion av elektrolytisk ozongenerator
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.
Ventral Töjning Pectoralt (VTP) som behandlingsmetod vid ett avvikande hållningsmönster i nacke och axlar : Single Subject Experimental Design
De senaste årtiondenas explosionsartade teknologiska utveckling har gett oss möjlighet till en mer stillasittande och inaktiv livsstil framför skärmbundna aktiviteter som datorer, surfplattor och smartphones. Det leder till en avvikande hållning. En avvikande hållning i nacke och axlar definieras som ökat framskjutet huvud, ökad thorakal kyfos samt protraherade (framskjutna) axlar. Genom ökad aktiv eller passiv tension av pectoralis minor har forskare antytt att det kan påverka skuldrans kinematik för individer med nack- och skuldersmärta. Syftet med studien var att utvärdera om töjning av pectoralis minor med behandlingsmetoden Ventral Töjning Pectoralt (VTP) har någon inverkan på individens avvikande hållning genom korrigering av axlarnas och nackens position.
