Controlled traffic for grass silage production : an economic evaluation for dairy farmers
The farm management system controlled traffic farming (CTF) aims to reduce soil compaction by restricting the field traffic from agricultural machinery to permanent traffic
lanes. Literature and empirical findings show that soil compaction and field traffic from heavy machinery may affect crop growth negatively, reducing crop yields. If grass-clover leys are subject to heavy field traffic the botanic composition might be altered, providing a lower
clover content in the forage. Clover as a silage feed is rich in protein providing good conditions for high yielding dairy cows. Grass-clover silage production is generally associated with intensive field traffic.
Darfur - Ett utdraget Rwanda?
In the Darfur region, located in the West of Sudan, there is a conflict between rebel groups and the government-supported Janjaweed militia. The fighting?s, which started in 2003, has caused the loss of at least 200 000 human life and more than 2 million people have fled their homes. The conflict has been described as a? prolonged Rwanda?.
Vad är vanvård? : - En kvantitativ studie om omsorgspersonalens kunskap om och inställning till lex Sarah och vanvård
Media has reported frequently about elder abuse in Sweden during the year of 2011. The authors have found an interest in elder abuse due to the attention about it and the law about the duty to report elder abuse, which is called lex Sarah. The aim was to investigate, due to quantitative method with surveys, the care givers tolerance to elder abuse, attitude and knowledge about lex Sarah. The result of the thesis was analyzed based on two theories, Lipsky?s street-level bureaucracy as well as Svensson?s, Johnsson?s and Laanemets? theory about knowledge.
Glukosamin som fodertillskott till häst
In this report female farmers use of technical equipment is investigated. There is little research made on this subject in Sweden, therefore this report can be seen as an explorative study. Research makes it clear that machinery, throughout history and even today, has been seen as a male area. Heavy machines are often associated with the same attributes as masculinity. Force, power, efficiency and control are some examples.
Flerpartslogistik med fokus på rutter, fyllnadsgrad och miljö
The globalization has increased the trade between different places and countries. Products are now available from all over the world, but this requires transports that have consequences in the environment as well as the economy. New professions are creates that do formality, organize, administrate and implement other businesses transports. Their operations are between the business and customer and they are called logistics companies. The purpose of this report was to study third-party logistics and why more and more companies use this logistics services.
Pneumatiska artificiella muskler : med hjälp av en robotarm
According to the study [1] several firefighters are killed in action each year. This happens naturally in various ways. One of the major factors is that firefighters often do not know how the environment looks like, for example that a building in an industrial area contains hazardous gas cylinders. Without a solution, fire-fighters will continue to die in duty. It is therefore important to solve this problem so that we can minimize the risks and save lives.The goal of this project was a control system for pneumatic artificial muscles.

Fordonsbestånd och nyregistreringar - en statistisk analys av regionala skillnader och strukturella faktorer
The official statistics on communication and transports in Sweden is administered by Statens Institut för kommunikationsanalys (SIKA). SIKA?s commission includes production of statistics on the Swedish vehicle fleet. These statistics provide important information tofinancial institutes, ministries, industry and mass media among others. Furthermore, the vehicle statistics include measures of comparison between different counties and municipalities.
Immunoglobulin VH gen analys in human B-cell
Malt lymphoma is a malignant disease that can arise in a variety of extra nodal sites. Previous studies indicate that tumour arise from more mature B-cells.Our purpose was to examine the presence of clonality and somatic hypermutation of immunoglobulin (IgV?) of MALT lymphomas.Paraffin-embedded tumour samples from13 MALT lymphoma were subjected to rearrangement analysis, by using PCR, heteroduplex gels and sequence analysis.Successful amplification was seen in 10/13 cases and sequences of IgV? genes were obtained in 6/13, all of them were mutated. The percentage of mutation compared to germline sequences was 1,1% to 8,6% monoclonal rearrangemang. It was demonstrated that 5 of 7 clones were derived from the V?3 family, 2 from V?1 and 1 from the V? 4 family..
Metalheads och Moralpanik : En undersökning kring Hårdrockens självpresentation, värde och kulturella etablering genom Close-Up Magazine
Uppsatsen granskar det spänningsförhållande som existerar mellan Hårdrockens uttryck och den oinvigda allmänhetens moralpanik. Genom självpresentation och smakdistinktioner undersöker den också hur Hårdrocken idag har positionerat sig som en etablerad kultur med ursprung och tradition. På så sätt behandlar uppsatsen vad och vem som definierar Hårdrockens kulturella värde och position. Undersökningen görs genom en textanalys av den svenska hårdrockstidningen Close-Up Magazine. Uppsatsen granskar även hur tidningen positionerar och presenterar sig som betydande aktör inom Hårdrockens verksamhetsfält..
CAP KC3-12 : Design and finite element analysis
In offshore oil production FMC Subsea systems use a product called cap. The cap´s mainly task is to protect hubface and seal areas on inboard hub against dirt, corrosion and mechanical damage under installation of a subsea system. A new model of a cap has been designed and analysed using finite element method. The model is called KC3-12 and has a new function, emergency release, which is a backup method for the ROV (remote operated vehicle) to release the cap from the hubface when it is placed under water. The cap KC3-12 was found to fulfil the criteria under the test load pressure, according to ASME VIII, div2.
Förskola och bibliotek - förskolorna som användare av och samarbetspartner till biblioteken i Kalmar och Växjö
The purpose was to examine how the pre-schools used the public libraries in two Swedishtowns. We also examined if and how the pre-schools and the public libraries were cooperating.Literature showed that it is possible to stimulate children's language development and this is a duty for pre-schools and public libraries. We sent an inquiry to all pre-schools divisions in both towns. We interviewed two librarians. Our results showed that the pre-schools did use the libraries to a great extent but they didn't cooperate with the libraries in the sense that they had elaborated agreements.

Mean value modelling of a poppet valve EGR-system
Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.
Pedagogers anmälningsplikt : - att anmäla barn som far illa
AbstractIn 1998 the Swedish legislation was sharpened, and active educationalists were legally bound to report any suspicion of child maltreatment. Nevertheless, there are a number of unrecorded cases of maltreated children, and research reveals that less than half of these children are reported to social services (Olsson, 2001). The purpose of the present study was to illustrate the problems with the mandatory reports in schools, as well as to study how educationalists proceed when they suspect that a child is maltreated. The method consisted of semi-structured interviews with five educationalists. The results revealed complex problems regarding educationalists mandatory reports.
