Djurvälfärd vid tidpunkten för slakt är en fråga som engagerar allmänheten. De flesta nötkreatur i Sverige bedövas med bultpistol inför slakt, med syftet att befrias från onödigt lidande. Undersökningar visar dock att bedövningskvaliteten i många fall inte är tillräckligt hög efter skottet. Den här litteraturstudien syftar till att undersöka hur en god bedövningskvalitet säkrast kan uppnås vid bultbedövning, det vill säga vilka vapen, vilken träffpunkt och vilken skjutkraft som har visat sig ge bäst resultat, samt hur situationen ser ut i dagsläget. Tidigare studier har visat att mellan 8,7 och 31,8 procent av djuren inte uppnår en god bedövningskvalitet efter skottet och statistiken ser ännu sämre ut för tjurar och äldre djur. Vilka indikatorer som används för att bedöma bedövningskvaliteten varierar lite mellan olika slakterier men den vanligaste och förmodat säkraste indikatorn är att titta på djurets eventuella kornealreflexer. Skottets träffpunkt finns reglerad i lagstiftningen men studier har visat att även avvikelser från denna punkt kan ge en god bedövningskvalitet om vapnet som används har tillräckligt hög kapacitet.

The jetengines of today are growing in complexity. Reliability for aircraft engines are of extreme importance, mainly due to safety reasons but also economical ones. This master thesis deals with faultdiagnosis in the turbine section of RM12, the engine used in Saab/BAe's Gripen. Three different faults which can occur in the turbine section was studied. These faults are: clogged fuel nozzle, hole in outlet guide vane and sensor fault.

The first version of the Swedish Code of Corporate Governance was published year 2004, by the code group, Kollegiet, after a mission from the Swedish government. The Code consists a collection of rules and standards about corporate governance and internal control, and the first version was intended to include incorporated limited companies on Stockholm?s alpha stocks, and also listed companies with a stock market value over three thousand million Swedish kronor. Now a few years have passed, and in July 2008 a new, revised version of the Code was implemented, now simplified and shorted, with the intention to include all joint-stock companies in Sweden. The Code contains rules about for example ownership, management commitments, annual stockholders meetings, and the accountant. This study intends to, with a qualitative research approach and an inductive reasoning, through studies of empirics in the subject, review whether the accountant?s profession has been influenced by the Code.

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

The increasing oil prices during the last years have made it profitable to use cereal grains as a fuel. When compared with wood, cereals contain higher amounts of Cl, S and ash. The Cl and S content makes the gases from cereal combustion more corrosive than gases from wood combustion. The goal of this master thesis was to find out the variation of Cl, S and ash content for oat grain grown under different conditions. Oats was chosen because in Sweden it's considered as the cereal with the best fuel qualities.

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

In tune with the cross-border trade the infringement of intellectual property rights has become a growing problem in Europe and the rest of the world. In June 2008 negotiations about a new international agreement was initiated between Europe, its member states and ten other countries, which will restrict infringements of intellectual property rights. The agreement is called ACTA, which stands for Anti-Counterfeiting Trade Agreement. On January 26, 2012 the European Union (EU) and twenty-two of its twenty-seven member states signed a letter of intent to the agreement and the EU?s internal processes of the agreement began.

Hunger is a problem in some parts of the world (www, FAO 1, 2012). The lack of food is often a result of insufficient knowledge in soil fertility management (Röing de Nowina, 2012). Ongoing hunger and malnourishment are quite prevalent in Sub-Saharan Africa and are often combined with poverty (www, FAO 1, 2012). Farming is the most common occupation in this area and the farms are often small-scale farms with subsistence crops and a few cattle. The farmers who operate these small-scale farms are economically a weak group.

Oilseed rape crops are an important in southern Sweden because of the high intensity of wheat growing. Pollen beetles are the most important pest in oilseed rape and causes often economic losses. Therefore it?s of great importance that we can control the population density, e g by using insecticides if necessary, to avoid mayor yield losses. In year 2000 pollen beetles were numerous in the province of Östergötland. The farmers sprayed with insecticides several times, but with low effects on the beetles. Field trials and laboratory experiments showed that pollen beetles had developed resistance against pyrethroids.

As revenues from newspaper advertising plummet and their readers loyalty erode, the need to understand newspapers' changing environment and the actors involved in this change is growing in importance. Evidence is the entire industry is entering into a restructuring phase and that this restructuring is driven by the rapid consumer adaption of internet media.In this thesis I elaborate on "how the Internet is affecting the conditions for value creation in printed newspapers" and "how the Internet is affecting the conditions for other actors involved in the printed newspaper's value creation". These two questions land us in the bigger question of "Does the Internet act as a compliment or a substitute to the printed newspaper ".To answer these questions the printed newspaper is represented as the actor in the middle of content producers, advertisers and consumers. It is in its role as a means of distribution and as a co-ordinating force that we study the value creation of the printed newspaper. The empirical base of this thesis is a qualitative participant observation where the author during a period of time interacted and collected data from the open discussion in blogs by several of the industry's top influentials combined with material from seminars and reports on the current state of media.

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

This study shows how to plan a pond with an ecosystem which although it will have turtles living in it will not need to be cared. I will also demonstrate how this pond would be designed to work in the natural landscape on Mallorca. The background to the study is that I am interested to investigate how plants that we in Sweden are using as indoor plants are growing in their natural landscape and how to build a land-scape with them. The study highlights different cleaning-systems that can be used to clean a pond in a natural way. A comparison will be made between the conditions of an exterminated turtle-species which will live in this environment and a species that is easier to care for.

Silviculture in young stands in Sweden is below the mark concerning what has to be done in the forest, and it is time to solve the problem. The problem will not be solved only by the private forest owners, professional help is needed. Skogsägarna Mellanskog is one of four forest unions in Sweden who wants to play a role and take responsibility for forestry in the middle of Sweden. This academic essay is based on a market survey sent to 350 forest owners in the Örebro district. 186 of them answered the questions, giving a response frequence of 53 percentage. The purpose of the essay is to find the determining factors which will make a forest owner to find a collaborator when planning and carrying out the silviculture measures in young stands. The result of the survey shows that the forest owners are anxious about the price and the costs. The costs have a severe effect if the silviculture measures in young stands will be carried out or not.

The purpose of this study was, if possible, to find a housing system for growing bulls that was as optimal as possible for the animal welfare. In order to select housing systems you must take into account the size of the group, body weight and the type of floor. Seven of the international most common housing systems were compared, straw bedding, deep straw bedding, sliding straw bedding, concrete slatted floor, rubber coated slatted floor, cubicles and feeding cubicles. Studies that have examined the proportion of tail, claw and leg injuries and the presence of unnatural behavior in the different systems. In summary, all studies showed that soft underlay were beneficial for the animals in terms of the proportion of bone lesions and swellings.

During the years 1950-75 was the construction of building apartments in high speed. A rapidly growing reconstruction requirement is the consequence of the rapid construction speed in these years. The technical lifetime of the different parts of the buildings is about to end and the needs for reconstruction is huge. One of Sweden's national environmental objectives is to reduce the urge of energy in buildings. This calls for radical measures to implement energy efficiency of existing assistance particularly in the assistance that is now facing reconstruction.
