Plasmodiophora brassicae ? host and environment interactions

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.

Kalvhyddans utformning : påverkan på kalvens hälsa och komfort

This paper aims to, through a literature review, examine how to best design and adapt calf huts to meet the calf's physiological requirements and reduce the infection pressure for enteric and respiratory diseases. It illuminates how the calf relates to different temperatures and climate, which temperature control mechanisms it uses and its ability to perform these regulations, as well as providing a summary of the past decades´ research on the calf huts housing system. These two theory chapters, along with a concluding discussion, provide a better understanding of how to, especially in temperate climates, design the most suitable calf hut, which cater to the calf's both thermal comfort and physical health. The literature suggests that the calf's own temperature control works well to counteract the temperature outside the desired range, and that one of the most important factors rather is ventilation of a calf hut, which reduces moisture and pathogens. The conclusion of this paper is mainly that there is not an obvious way to place and construct a calf hutch and that most design principles contribute to both positive and negative effects simultaneously.

Interorganisatorisk styrning av leverantörsrelationer inom lågprismodebranschen: -En fallstudie av lågprismodeföretaget BikBok

This thesis concerns the control of outsourced interorganizational buyer-supplier relationships in the low-price fashion industry. A qualitative case study has been performed on two supplier relationships of a low-price fashion company. By identifying specificities of the industry and relating them to control problems and their implications on control solutions, the thesis has established a relation between industry specific characteristics and the way companies in the industry control their supplier relationships. The analysis is based on a theoretical framework created by Dekker (2004). Amongst other factors, the difficulty to define, quantify and measure the design variables of a fashion good, the high heterogeneity between individual products and the difficulty to predict the trend based demand, create high coordination requirements as well as appropriation concerns solved through extensive formal control.

Modellbaserad prediktiv reglering av en dieselmotor med variabel geometriturbin och återcirkulering av avgaser

Control of a diesel engine equipped with Variable Geometry Turbine (VGT) and Exhaust Gas Recirculation (EGR) requires a multivariable control method. One problem is that the engine system is non-linear. Furthermore there are strong cross-connections between inputs and outputs and the inputs have alsoboundaries. To be able to manage these control problems, MPC has been used that is a multivariable method. The MPC-controller consists of an optimization problem and therefore MPC can find the optimum control signals in an easy way.

Budget som styrmedel ? ett effektivt verktyg eller ett onödigt ont?: En fallstudie av den ekonomiska styrningen inom Luftfartsverket

The aim of this Master?s thesis is to examine the function of the budget as a means of control within an organisation in the public sector. To accomplish this, a case study has been conducted on a certain business unit within Luftfartsverket responsible for providing Air Traffic Control services. The thesis is built on a framework of contemporary theories of budgeting and includes a brief discussion of the weaknesses usually associated with the traditional budget. The conclusion of the study is that the use of budget as a means of financial control within Luftfartsverket is not efficient enough at the moment.

Kvalitetssäkring och processtyrningav ytstruktur på lackerat objekt

To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..

Ekonomistyrning i interorganisatoriska relationer

Background: Inter-organisational ways of working have become more and more common during the last decades. In order to attain efficiency and productivity, such inter-organisational relationships need to be governed and controlled. However, studies have shown that inadequate control is one of the main reasons for why inter-organisational relationships fail. One of the means that can be used for governing and controlling a business is management control. The use of management control in inter-organisational contexts is a quite unexplored area of research at the present time, which might seem somewhat surprising considering the fact that inadequate control is a common explanation for why inter-organisational relationships fail.

EN KARTLÄGGNING OM VÅRDPERSONALENS KUNSKAP OM BASALA HYGIENRUTINER : - Enkätundersökning utförd på Skaraborgs sjukhus

Bakgrund: En vårdrelaterad infektion (VRI) är en av de vanligaste komplikationer som drabbar patienter som vårdas på sjukhus eller andra vårdinrättningar; uppskattningsvis drabbas cirka 10 % av patienterna. Basala hygienrutiner är en effektiv metod för att förhindra kontaktsmitta och därmed minska spridningen av VRI. Enligt Socialstyrelsens föreskrifter om basala hygienrutiner inom hälso- och sjukvården ska vårdpersonalen för att begränsa VRI iaktta dessa åtgärder vid all undersökning, behandling eller annan direktkontakt med patienten.Syfte: Syftet med studien var att kartlägga vårdpersonalens kunskaper om basala hygienrutiner och om det finns faktorer som påverkar följsamheten till de basala hygienrutinerna.Metod: Studien hade en kvantitativ ansats med icke experimentell design, där personalens kunskaper om basala hygienrutiner beskrevs och mättes. Hypoteser utformades och testades. Deskriptiv- och sambandsanalys genomfördes på resultatet.Resultat: Kunskapsnivån hos personalen är relativt hög men förbättringspotential finns.

Intern kontroll : Inom mindre grossistföretag

Accounting is a well discussed topic, and an important tool that allows stakeholders and others to interact with the companies. To gain credible reports, the companies require maintenance, activities and monitoring. Wholesalers account for approximately 20% of Sweden's net and is increasing at a steady pace. Few studies on wholesalers are acquired and the internal control has shown to be important for the preparation of the financial statements.Therefore the study will be focusing on the smaller wholesaler?s internal control, all the way to the financial statements.

Patienters upplevelse av att vårdas i isolering : en litteraturöversikt

Background: Isolation care may be necessary when a patient is carrying infection or is being inflicted with disease that causes deficit immune system. Being isolated means that the patient is in a confined space and may stay only there. Even in ancient times, people discovered the importance of isolating people carrying an infection from the rest of society. According to the Infectious Diseases Act, patients should be isolated in order to reduce the spread of infection both from the patient to the surroundings as well as the opposite. Isolation care can be psychologically stressful for some patients.

När gränsen för styrning suddas ut - En fallstudie av hur ett företags styrning påverkar dess kundrelationer

As collaboration between companies move beyond the single transaction into more long-term relationships the consequences of a company's control system become more complex. The aim of this paper is to provide an understanding of how intra- and inter-organizational control and work practices interact through examining how a company's intra-organizational control influences its customer relationships. The empirical research is performed through a qualitative case study where interviews have been conducted with management and sales staff within the case company as well as with one of the customers. The empirical findings have been analyzed using frameworks and theories regarding management control and customer relationships. The study reveals that the intra-organizational control of the case company affects its relationships with customers in a number of ways.
