One way of signalling commands to the horse during riding is through applying tension on the reins to create bit pressure in the horse?s mouth (Terada et al., 2006; Clayton et al., 2011). The skilfulness of the rider in using the hands when applying bit pressure has consequences both for the horse?s performance and welfare (Manfredi et al., 2010). At the trot there are large vertical deviations of the horse?s body which the rider must adjust and adapt to (Terada et al., 2006) and an unsteady hand due to inability to follow the horse?s movement can be a source of discomfort and conflict behaviour in the horse (Heleski et al., 2009).

From embankment dams is something that has long been noticed and given rise to different questions. The most serious question is if the sludge is a result of inner erosion through the dam, and thus consists of material transported from the dam. Concerns have also been raised whether the sludge could interfere with the systems drainage capacity and thereby lead to high pore pressure in the dam, or if the measurement of seepage is disturbed, as the measuring is usually made via Thomson weirs, which could risk being blocked. The result of this investigation shows that the sludge is a result of the oxidation of iron by iron bacteria, and to the greater part consists of these oxides as well as the bacteria?s own structures. The iron oxidizing bacteria, FeOB, oxides ferrous iron to ferric as a part of their metabolism, and thereby create large quantities of iron(oxy)hydroxides.

Bakgrund och problem: Olika belöningssystem har den senaste tiden skapat stora rubriker massmedialt. Belöningssystem används som ett styrningsverktyg för att skapa incitament hos de anställda samt motivera dessa till att göra ett bättre arbete. Det är av stor betydelse att de anställdas mål överensstämmer med företagets övergripande mål och strategier. För att uppnå detta mål inom företaget som vidare skapar effektivitet används en rad olika belöningsformer. Dessa är såväl monetära som icke-monetära samt delas ut kollektivt och/eller individuellt.

Bakgrund och problemEtt generellt problem är att forskning baserad på små och medelstora företag är mycket liten, med avseende på ekonomistyrning samt mätning av resultat.SyfteSyftet är att beskriva och analysera vilka mått som används i fyra små tillverkande företag. Hur måtten mäts, hur informationen kommuniceras kring dem, i vilket syfte de används och om måtten är kopplade till något mål i företaget, är frågor som studien vill besvara. Uppsatsen syftar till att skapa en ökad förståelse för hur små företag mäter sin verksamhet i avsikt att bedöma sitt resultat.Metod Med en abduktiv ansats och hermeneutiskt synsätt har den empiriska och teoretiska referensramen insamlats. Genom en kvalitativ studie och besöksintervjuer hos fyra små tillverkande företag har vi fått möjlighet att beskriva och analysera hur de använder sig av mätning i sin verksamhet. Teoriramen har sedan använts för att skapa en djupare förståelse för empirisk data.SlutsatsDe mått som används i små företag måste utformas utifrån varje företags specifika förutsättningar för att träffa rätt då många faktorer spelar in i valet av mått.

Sahlgrenska Academy at University of GothenburgDepartment of Internal medicine and Clinical nutritionAbstractTitel: Can omega-3 prevent the emergence of allergy?? A systematic reviewAuthor: Karin Andersson and Cecilia BjörertzSupervisor: Henriette PhilipsonExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 hpType of paper: Examination paper, 15 hpDate: 2012-05-23Background Today allergy is a major public health issue and one of our most common chronic diseases. It would be most profitable if there was a way to prevent the emergence of allergies, both regarding the community and the individual. The antiinflammatory property of omega-3 influences the immune system and is thought to have a preventive effect on allergic symptoms. To investigate whether the mothers intake of omega-3 during pregnancy and lactation affects the child?s future development of allergy is therefore of high interest.Objective To examine if omega-3 supplement given to mothers during pregnancy, or pregnancy and lactation, is shown to be beneficial in children with heredity to develop allergy.Search strategy Articles were collected from the data bases PubMed, Cochrane and Scopus.

One must consider cost effectiveness when deciding how resources within the health sector should be distributed. Quality adjusted life years (QALYs) are used to measure the value of different medical treatments. QALY is based on utility maximization theory, which suggests that a QALY is always a QALY regardless of who receives it. Therefore, a produced QALY is worth the same regardless of the age or the initial health of the patient. Previous research has shown that these assumptions do not seem to fit the real preferences of individuals.

Bakgrund och problemdiskussion: När IAS 40 Förvaltningsfastigheter blev tillämplig 2005 tilläts förvaltningsfastigheter värderas till verkligt värde. En del problem har framkommit genom införandet av värdering till verkligt värde av förvaltningsfastigheter. Detta har lett till att IASB i samarbete med FASB arbetat fram en ny standard, IFRS 13 Fair value measurement, som behandlar hur värdering till verkligt värde ska gå till. Syftet med samarbetet av den nya standarden var att få en mer harmoniserad, globaliserad och jämförbar redovisning. Då det idag inte är självklart hur värdering till verkligt värde ska gå till vill vi utreda om införandet av IFRS 13 kan komplettera IAS 40 och ge mer vägledning för värdering av förvaltningsfastigheter.

This report describes an investigation of the indoor climate in two different workspaces. Since we a big part of our lives are staying indoors in artificial environments, and more particularly in our workplaces, we think it would be interesting to do this investigation. The technical solutions for air treatment systems began with simple natural systems without fans and where the thermal rise of the air applied. In modern time is technical air treating systems used to take care of the fresh air supply. This type of units can supply filtered air with the right temperature to the building. Well-functioning ventilation is essential to bring clean fresh air to the room and effectively remove impurities without sound- or draught problems. The indoor climate is relevant for the output capacity.

In order to facilitate testing of anesthesia machines a patient simulator has been required by Maquet Critical Care AB. A patient simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient simulator has fulfilled the requirements.

Emotron is a company specialised in developing, producing and marketing equipment to con-trol, monitor and protect processes and machinery driven by electric motors, with an applica-tion focus. Examples of uses for their products are fans, pumps, lifts and cranes.The project is to look at Emotrons end of line test. The company has seen that at the final test-ing there is a bottleneck that restricts the outflow and prevents an increase in the number of tested products.The purpose of this project is to review how Emotrons end-of-line test works today and if there is a possibility to make the test more efficient in such a way that the quality is not at risk, while increasing the outflow of tested products.The projects first step is to look at and analyse what is causing the bottleneck at the end-of-line. When the analysis is complete, the next step is to review whether there is a possibility to solve the bottleneck and if so in what way can this be done. Emotrons most overall objective of the project is to increase the outflow of the number of tested products without jeopardizing the quality.An analysis has been made on frequency inverters, soft starters and shaft power monitors.

The aim of this thesis was to answer a number of questions about the environmental consequences of aircraft de-icing. A further aim was to suggest how the environmental consequences due to the release of de-icing fluids can be measured and reduced.The main impact of the aircraft de-icing on the environment is due to the large oxygen demand for the degradation of glycol based de-icing fluids which are released in the environment. The effect of the increase in oxygen demand depends on where the degradation occurs in the ecosystem. In a sensitive ecosystem, the large demand of oxygen could provide an anaerobic environment which would be harmful for many types of organisms.In order to reduce the negative effects of the applied de-icing fluid, there is some type of collection system at every regular airport in Sweden. The methods of collection can be divided into two general groups, hydrological isolation or vacuum sweeper trucks.

The purpose of this study is to incrementally, through a combination of various methods, examine the assumptions about the working economic outcomes that can be made based on planned ergonomic intervention in a department at Pfizer Health AB in Strängnäs. The study contributes to knowledge about how assumptions on OSH financial results can be made, based on planned ergonomic interventions. These assumptions were based on biomechanical calculations made on the basis of ergonomics measurements with inclinometer. The study is important because previous research has shown that poor work environment have a bad impact on the economy of a company in different ways. It can for example be negative impact on the company's productivity and quality of the units produced or the services provided.

The Swedish beef cattle population is growing when the dairy cattle become fewer. The fertility of the beef cows is important for the profitability in beef cattle production. Today there is no genetic evaluation for female fertility in Swedish beef cows. The purpose of this study was to see if calving interval can be used in the genetic evaluation as a measure of female fertility in beef cows. For this purpose the variation in calving interval for beef cows of different breeds and ages registred in KAP was studied.

Vaccination of fish can be assumed to cause pain. This study was designed to see if we can minimize the suffering of fish following vaccination. Fishes are cold-blooded animals and thus more primitive than warm-blooded animals. Despite this, many organs, e.g. the nervous system, have the same basic structure as that of other vertebrates. The fibre system for conducting pain is more diffuse than in humans.
