There are two species of potato cyst nematode (PCN), the yellow, Globodera rostochiensis, and the white, Globodera pallida. Each of them can appear in different pathotypes. These are separated by testing the nematode ability to multiply on a number of potato cultivars with different resistance properties. The aim of this project was to examine the virulence of Swedish and foreign PCN populations and to compare two test methods. Biotests are today the only available tests used to study virulence.

AbstractAim: The aim of this study was to investigate if treatment with ?dry needling? in myofascial triggerpoints (MTrPs) in the rotatorcuff muscles may affect impingement symptoms such as pain during provocative tests, shoulder mobility, and function. The research questions were: Does the value of pain change on the Visual Analog Pain Scale (VAS) between before and after treatment? Do the positive provocative tests for impingement change between before and after treatment? Does the active shoulder mobility change between before and after treatment? Does the self-rated function change between before and after treatment?Method: The study was a prospective randomized intervention study and 19 persons with impingement symptoms (mean ± standard deviation; 58 ± 18 years, and shoulder pain duration 3.9 ± 1.6 months) were randomized into two groups. The groups were tested before, directly after and 3 weeks after treatment.

This study aimed to investigate whether there was a correlation between an individual?s selfesteem and search for confirmation on social media. The study also sought to answer whether there were differences in self-esteem and search for confirmation from a gender perspective. In this study social media was defined as Instagram. The choice was founded on the basis that Instagram in the current situation is one of the world's largest social media that allows users to share their everydaylife in pictures, which are commented and ?liked? by other users.

This thesis has been carried out in cooperation with a company which develops mobile sensor platforms. The sensors measure different types of data such as temperature, pressure etc.. They will communicate through the internet with a server that stores data in a database. This system will be controlled and monitored through a web page. The project's aim has been to develop this system and to implement a server, a database, a website and a client application that simulates sensor signals.

The Swedish regions are new phenomena, from the start from the new regionalism which started in the 1980´s. The purpose of the thesis is to analyze Region Skåne and Västra Götalandsregionen to come to a conclusion which model of region they are and want to be by using theories of regional identity and identity of politics and see similarities and differences. My research question is: Which of cultural, administrative and functional region are Region Skåne and Västra Götaland striving to construct?   The methods I have used are qualitative text- and content analysis to analyze the regions, by using theories about regional identity and identity of politics. Furthermore, I am using some statistic from SOM-institutet to analyze the regional identity in the regions.   The result show that Region Skåne is constructing a cultural region, because of their strong regional identity and that the politicians are using identity of politics to combine the citizens.

Bakgrund: Reumatoid atrit (RA) är en av de mest kända reumatiska sjukdomarna och kan beskrivas som en kronisk, systemisk, inflammatorisk sjukdom. Sjukdomen drabbar ca 1 % av befolkningen. Fysiologiska och anatomiska störningar som kan drabba personer med RA är rörelse- och belastningssmärta, nedsatt rörlighet, leddeformitet, nedsatt muskelfunktion och nedsatt kondition. Syfte: Att undersöka vilka metoder för, och vilka effekter av, fysisk träning som fanns dokumenterade i vetenskaplig litteratur för personer med reumatoid artrit. Metod: En datasökning gjordes på databaserna PubMed, SweMed + och Cochrane.

A Quick Test (AQT) Färg och Form är ett test av snabb automatiserad benämning avsett att detektera kognitiva störningar. Det består av tre delar som var och en utgörs av 40 visuella stimuli som skall benämnas så snabbt som möjligt. Tidigare studier har indikerat att AQT skiljer personer med Alzheimers sjukdom från friska kontroller med högre precision än det ofta använda Mini-Mental-Testet (MMT). I denna studie undersöktes för första gången om AQT-resultat kunde predicera diagnosen hos en konsekutiv serie patienter vid en minnesklinik samt relationen mellan AQT-resultat och biomarkörer (likvorproteiner) för neurodegenerativ sjukdom. 492 svarsblanketter från AQT Färg och Form analyserades och diagnostisk prediktion samt korrelation med nivån av likvorproteiner fastställdes för de 374 första patienterna i serien.

Sweden have 419 000 km road in the country and about half of these roads is forestroads. The forest road net most important mission is to make it possible to deliver wood from the forest to the industries. With a raw material that is spread over a large area the road network is important. Each year has the forest road network been extended with about 1 700 km new roads. To decide if a new road is to be built different forest road cost estimation models has been used.

Modern agriculture equipment are more computer based today, and many equipments use a terminal in the tractor where the driver have the opportunity to make adjustments to the equipment. This is the reason why ISO developed a new standard called ISOBUS. It is a communication standard based on CAN specially adapted for griculture equipments. The purpose of the standard is that it should be ossible to equip a tractor with a standard terminal called Virtual Terminal that can be used to control the equipment. The use of the terminal should be independent of the manufacturer of the tractor as well as of the equipment.The purpose of this report is to ?nd a solution of how to use CC Systems on-board computer, CCP XS, as a Virtual Terminal.

Functional Magnetic Resonance Imaging, fMRI, can be used for analyzing brain activity in subjects performing language tasks. The purpose of this study was to develop aphasia-friendly information adjusted to aphasic subjects participating in fMRI studies. The objectives were to investigate if adjusted information was important for the ability to perform language tasks and if the information could be used for different types of aphasia.Sixteen aphasic subjects participated in the study, six of these underwent fMRI. The participants varied in grade and type of aphasia. They had Swedish as their native language and were aged between 26 and 89, mean 57.

The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.

Functional Subgrouping är en metod för konflikthantering, användbar på såväl individ, grupp som organisationsnivå. Konflikter kan definieras som meningsskiljaktigheter innefattande störningar i kommunikationen vilket kan leda till psykologisk belastning på individer. Vikten av funktionella konfliktlösningsstrategier är således stor. Syftet med föreliggande kvalitativa studie var att skapa övergripande förståelse för metoden utifrån användning samt för- och nackdelar i relation till annan konfliktlösning. Fyra halvstrukturerade intervjuer genomfördes vilka analyserades tematiskt.
