In this thesis, three separate experiments have been performed on different aspects of the interaction between the causal agent of clubroot, Plasmodiophora brassicae, and its hosts. In the first experiment the pathotype of the P. brassicae single spore isolate, which is currently used to construct a reference genome, has been classified using the ECD bioassay. The disease severity of infected plants was scored according to two different scales and the pathotype was determined according to three previously published guidelines. The results were compared to previous published studies describing the e3 isolate. The life cycle of P. brassicae is not well understood.

Bovine viral diarrhoea virus (BVDV) is the causative agent of a complex of disease syndromes in cattle with high economical and welfare impacts. BVDV occurs as two biotypes; cytopathic (BVDVcp) and noncytopathic (BVDVncp) determined by differential effects on cultured cells and can also be divided into two genotypes (BVDV1 and BVDV2) on the basis of genomic diversity. The interaction between BVDV and the host?s immune system is regarded a key aspect in the sequel of BVDV infection. Infection with BVDV normally causes an acute transient infection, with mild to subclinical signs, but occasionally results in severe and even fatal disease.

Barley is one of the most important cereals cultivated in the Nordic countries. Climate change brings warmer and moisture climate which favors fungal diseases. In the cropland barley can be seriously infested with hard fungus attack. Since it is important that the yield bears a high quality it is of great importance to find varieties more resistant to attacks.Pathogenesis-related (PR) proteins are stress proteins induced in the plant in response to infection and abiotic stress (van Loon, 1997). PRs are shown to have antimicrobial activity differing between bacteria, fungi and oomycetes (Tandrup Poulsen, 2001).

This study was conducted at the City Abattoir in Kampala, Uganda to evaluate the cleaning process, with focus on bacterial pathogens, in a pilot scale integrated bioprocess. This consisted of four steps: anaerobic sequencing batch reactors; aerobic/anoxic sequencing batch reactors; a high performance temperature controlled methanogenesis digester and a constructed wetland. The objective was to determine if this type of cleaning process could be used to clean wastewater from abattoirs in a satisfactory way. The indicator organisms for faecal contamination, Escherichia coli and Enterococcus spp. were used to investigate in what numbers bacteria could be found in the untreated wastewater and how much that was reduced in the different steps of the cleaning process. The water was analysed for Salmonella to see if human pathogens could be found and could survive the different steps of the treatment process.

Titel: Frivillig revision ? Varför väljer aktiebolagets företrädare att ha eller inte ha revisor?Nivå: C -uppsats i ämnet företagsekonomiFörfattare: Annelie Molin och Eva WidellHandledare: Ann Wetterlind-DörnerDatum: 2012 ? MajSyfte: I denna pilotstudie vill författarna se varför företrädarna har valt att ha eller inte ha revisor i bolaget, sedan möjligheten med frivillig revision infördes.Metod: Författarna har använt sig av enkäter som de skickat ut till bolagen, samt formulär till Bolagsverket och Skatteverket. Med hjälp av böcker, vetenskapliga artiklar och rapporter etc har författarna sedan analyserat svaren de fått.Resultat och slutsats: Det finns en ekonomisk vinnig med i resonemanget kring valet av att ha revisor eller inte ha revisor och det är viktigt för den enskilde företrädaren att noggrant analysera för- och nackdelarna och utifrån detta göra sina val.Förslag till fortsatt forskning: Det skulle vara intressant att följa upp studien om något år och se om åsikterna bland berörda parter förändras vartefter tiden går.Uppsatsens bidrag: Pilotstudien kan ge framtida forskare en inblick i hur bolagens företrädare uppfattar den frivilliga revisionen och anledningen till varför de gör på ena eller andra sättet i dagsläget. Med hjälp av pilotstudien kan de sedan utveckla egna idéer till nya forskningsfrågor eller att utveckla sina egna tjänster som riktar sig till bolagen..

Introduction Malignant lymphoma is the most common haematological blood cancer diagnosis. In spring 2013 a questionnaire was handed out to patients with various haematological malignancies. The results showed that the patients requested more verbal and written information about their disease and treatment. Providing information about chemotherapy and how it affects the patient's quality of life is part of the nursing care. Communication between nurse and patient is very important to share experiences and knowledge with each other Aim The aim is to describe the information and communication patients with malignant lymphoma demand, based on their own experience, in meeting with the nurse before and during curative chemotherapy treatment at a haematology outpatient clinic.

The purpose of this thesis was to examine if users of digital music games may acquire skills from the games that may be of use in learning to play a real instrument, that is a non-digitally simulated instrument like an acoustic piano. We have used Gee?s theory regarding a possible interconnection between different semiotic domains, and how this connection may enable a transfer of skills between related domains. In this thesis we examine possible skill transfer between the domains ?digital games? and ?non-digital instruments?. To examine our question formulation we chose to conduct a pilot study from which we collected both quantitative and qualitative data.

Bakgrund: Internationellt existerar fortfarande illegala aborter med kvinnans hälsa, och i somliga fall liv, som insats. Inom gynekologisk vård i Sverige arbetar allmänsjuksköterskor vilka vars arbetsuppgifter bland annat består av att vårda kvinnor som genomgår inducerade aborter. Deras arbete vilar på den svenska abortlagens bestämmelser om kvinnans rätt till fri abort samt den övergripande hälso- och sjukvårdslagen. Allmänsjuksköterskor har fått en mer framträdande roll i arbetet med inducerade aborter i takt med den ökade användningen av den medicinskt inducerade aborten. I sitt arbete ställs sjuksköterskorna inför specifika arbetsuppgifter vilka kan tyckas påfrestande.

Syftet med denna uppsats är att jämföra/analysera förmågorna till Suppression of Enemy Air Defences (SEAD) hosJAS 39 och en svensk UCAV år 2015. Årtalet 2015 är valt för att flera bedömare anser att det är först vid dennatidpunkt som en Unmanned Combat Air Vehicle (UCAV) har en utvecklingsnivå som tillåter att de sätts in i SEADuppdrag.I uppsatsen redovisas vilka krav som ställs på en plattforms sensorer och bekämpningsförmåga för attgenomföra ett SEAD-uppdrag mot två utvalda typer av mål. Därefter sker en jämförelse mellan de båda farkosternasförmåga att detektera respektive bekämpa de båda målen. Resultatet visar att JAS 39 som bemannad plattform har enfördel i de fall då operationer är hårt styrda av Rules of Engagement (ROE), särskilt gäller detta vid fredsbevarandeoperationer. Uppsatsen visar även att flygplanradarns förmåga att upptäcka och identifiera markmål är beroende avinförandet av en SAR-mod.

This is a study of some risk factors for Diabetes Mellitus (DM) in dogs. As a pilot study it is meant to give information to be used in a planned later, larger and better controlled study. The present study hypothesized that suboptimal feeding (high percentage of homemade and table foods), lack of activity and overweight contribute to the risk of DM. Twenty consecutive dogs diagnosed with DM at the Veterinary University Clinic in Uppsala between 2000 ? 2003 were chosen as the experimental group.

Människan inhämtar och bearbetar information via sina sinnen för att skapa en bild av omvärlden. Mängden information som människan kan bearbeta är begränsad, speciellt i komplexa miljöer där flera uppgifter ska utföras. Fokus för denna studie är att reducera piloters kognitiva belastning för att underlätta i svåra flygsituationer. Ett stort problem idag är att när en pilot förlorar yttre visuella referenser så kan spatial desorientering uppstå. Ett resultat av det kan vara att helikoptern börjar driva utan att piloten märker något.

A range of public health and animal welfare problems has been shown to be associated with free-roaming dogs. With a high density of free-roaming dogs and with a major tourism industry, Samoan tourists are likely to be influenced by the presence of the dogs. The tourists are mainly from the Oceanic region; with New Zealand and Australia as the biggest contributors. The aim of this study was to examine the potential impacts of dogs on visitors to Samoa. A questionnaire was handed out to 281 visitors all over Samoa, collecting opinions and information on visitors? experiences and behaviour regarding the Samoan dogs.

This thesis looks at two sides of the same coin: how to support the production and future development at a specialist medical technology department at Danderyd Hospital. The two sides are; a pilot study of a product management system (PDM) and an interview based study on the characteristics of the silent knowledge of the technicians. The department (National respiratory centre, NRC) is facing retirement of several key employees.The technical study shows that the success of an implementation is largely dependent on the users? prior knowledge and use of a 3D Computer aided design system (CAD).The system itself is shown to fulfill the Lifecycle requirement of tracking the products (mostly tracheostomy tubes) but without a CAD centered workflow, some substantial education and preferably some new recruits, an implementation of the PDM system will fail. The author recommends development of the current ?low-tech? system of MS Excel and Access rather than redistribute the dependency from technician towards a complex, commercial software and its vendor.The analysis of the technicians? silent knowledge with the newly developed method, epithet for silent knowledge (ETK), shows that the longer employment time:the more differentiated technicians become in describing their work,practical knowledge are regarded higher andthe social and collective problem solving factors of the work becomes more important.Typically, it is shown that a new employee should preferably enjoy problem solving, being pragmatic and social as well as having some prior education or work experience in a CAD and/or a PDM system..

Masters thesis in Business Economics IV, VT 2012Linneuniversity in Kalmar Authors: Johanna Susaeg and David JohanssonTutor: Petter BoyeExaminer: Karin JonnergårdTitle: Fair value - How real is it? Background and research discussion: The concept of fair value is today connected with great uncertainty, which may be a result of the various guidelines developed during recent years. Hence, auditors have an important role in situations where they have to make projections concerning fair value and also do inspections of the management´s own assumptions.     The critique that has been shown regarding fair value is that it can be difficult to estimate, especially when there is no active market to proceed from. This problem has been confirmed through that the management often uses the estimations subjectivity to deliberately show higher or lower values in the accounts. Purpose: The purpose of this essay is to study and describe auditors, appraisers and real estate companys interest and procedure in valuation of real estates.  We also going to describe theirs view on fair value of real estates plus analyze and explain the actor?s roles in the valueprocess and how their particular interests can affect the final valuation in different situations. Methodology: The study is characterized by a qualitative method containing a pilot interview and several personal interviews with auditors, estimators, and real estate companies.

Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium phosphate and a main component of bones and teeth. The purpose of the present study is to make oriented nano-sized composites with CNC and HAp. Although some researchers carried out to make CNC composites with HAp for biomedical materials, nano-sized and oriented ones haven?t been achieved yet.
