This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.

In this study, the sea trout (Salmo trutta) spawning migration was studied in the river Själsöån, Gotland, to assess the main external factors determining upstream migration and seasonal changes in fish parameters. Additionally population trends were studied by examination of old data. The most important external factors for upstream migration were the air pressure, air temperature and wind direction. No significant difference was found between when males and females migrated upstream. Larger females in better condition started migration earlier than the smaller females in poorer condition.

There is an increased pressure for firms to provide the financial market with additional information. Such disclosure is attached with different kinds of costs. In spite of these costs, and in spite of increased mandatory disclosures, firms choose to voluntary disclosure financial information to analysts and others. This indicates that firms also benefit from providing additional information. The subjects of this study is 431 annual reports from firms listed at the Stockholm Stock Exchange for 2002 and 2005 and the objective is to survey factors that can explain variations in firms? voluntary disclosure.

Syftet med denna studie var att klargöra eventuellt samband mellan nutrition och trycksår genom att söka svar på de tre frågorna: Har nutritionen någon betydelse för uppkomst och läkning av trycksår? Vilka näringsämnen behövs för att förhind-ra uppkomsten och främja läkningen av trycksår? Finns de något samband mellan malnutrition och/eller ätsvårigheter och trycksår? Metoden för denna litteraturstu-die innefattade systematisk databassökning och manuell sökning av artiklar från referenslistor. Tio vetenskapliga artiklar med kvantitativ forskning i ämnet har analyserats och sammanställts. Resultatet presenteras i följande fyra tema: Nutri-tionens betydelse, energiintagets betydelse, vitaminers och mineralers betydelse samt bifynd. Analysen indikerar på samband mellan förbättrad nutrition och både minskad incidens och förbättrad läkning av trycksår..

The problem presented in this report is that of finding a method to calculate the lift force from a single-element airfoil of arbitrary shape. A number of restrictions are used in order to simplify calculations while retaining reasonable accuracy. The problem is solved for the two-dimensional case only and no finite-wing effects are taken into account. Furthermore, inviscid and incompressible flow is assumed. The method used to solve the problem is the vortex panel method, with vortex singularities distributed over simplified airfoil geometry.

This thesis is based on a case study of the City of Stockholm. The study aims to explore the effects on the city's large investments caused by the public reform. Furthermore, the question concerns the character of the impact and if it will affect what type of investments that will be prioritized. The theoretical background is based on Brunsson's ideas about political organizations shifting towards corporate nature, and Almqvist's interpretation of New Public Management (NPM). Moreover, models explaining public management reform, and the main components of corporate shifting, are used.

Environment friendly transports are one of the main topics in the industry and society today.Shell organizes an annual university competition called Shell Eco Marathon. The goal is to buildthe car that consumes the least fuel during a race. KTH participated for the first time in 2006.The engine for this competition, DoubleTwo, has been developed within the school. Theprinciple is a two stroke counter piston HCCI engine with variable compression ratio. HCCIstands for homogenous charge compression ignition.

To succeed, and make money at your animal production you need to feed your animals with high quality fodder. Other condition to succeed is that you keep your production costs at a minimum. To be able to produce baled silage at a low cost it?s very important that the bales have a high density. Density is measured in kg dry matter (DM) per cubic meter. The purpose with this report was to learn more about making silage in round bales and to how much the bale density varies between different brands of round balers.

Public procurement stands for a substantial part of the total food consumption in Sweden. The majority of the procured food is today imported and according to market trends it?s intended to stay that way. Imported food is favoured for locally produced due to price pressure. Consequently domestic pork farmers have declined by 25 percent during the last twenty years.

Every year big events takes place in different cities, one of the largest half marathons in the world is located in Gothenburg and is called GöteborgsVarvet. These kind of events rely on volunteers to even be able to manage the pressure from the arrangement. The purpose of the study was to investigate the motivation factors among volunteers? at GöteborgsVarvet 2012. This study is a part of a bigger project called EVINN that is an EU-financial researchproject which aims to develop arrangements.

This essay investigates the work situation for teacher educators at a university with focus on the subject areas education, research and administration. The research questions contain the work situation the teacher educators have, how they apprehend it, and how they find their position within the work organisation. Six interviews have been executed at the teacher education at a university. Some of the results from the investigation indicate that the teacher educators find education to be very a very demanding work and that the split of work during the academic year is uneven. The work with administration before and after the education, for example work with syllabuses and descriptions for courses, are activities demanding much time.

Patienter med trycksår lider av både fysisk och psykisk ohälsa. Många av dem är oftast äldre, stillasittande och kanske även undernärda. Författarna ville undersöka hur trycksår kunde förhindras samt läka bättre. Syftet med denna studie var att undersöka betydelsen av korrekt riskbedömning för trycksår så att preventiva åtgärder sätts in i rätt tid. Vidare var författarna intresserade av hur en adekvat näringstillförsel inverkar på sårläkningsprocessen.

The aim was to examinehow managers, based on similar education and policy background, perceive their leadership today, and how it according to them, maybe developed in the future.
