The main purpose of the catch crops is to reduce leakage of nitrogen. They are sown after the main crop and killed before the next crop. In Sweden the farmers gets subsidies to establish catch crops.
The thesis is limited to the trail L3-9010 sited at HS- Malmöhus, Borgeby Gård, 237 91 Bjärred, Sweden, 2007. Only treatments with oil radish, white mustard and the reference treatments were studied.
Styrlagar för en höghastighetsrobot
För att en målsökande robot skall träffa sitt mål behövs det som på engelska kallas guidance. På svenska brukar det kallas styrlagar. Styrlagarna är referenssignaler till styrautomaten i form av accelerationskrav i girled och tippled. I detta examensarbete har fyra olika styrlagar härletts teoretiskt och implementerats i en simuleringsmodell bestående av robot och mål i en omgivning. Rapportens huvudsyfte är att utreda vilken styrlag som passar bäst till en höghastighetsrobot.

Elevers och lärares förväntningar på studie- och yrkesvägledning
För individer med parodontal sjukdom är egenvården betydelsefull för en bättre prognos. Förebyggande åtgärder kan behöva ses i ett större sammanhang om det ska vara möjligt att främja tandhälsa eller förhindra fortsatt tandsjukdom. En insikt i patientens upplevelser och syn på sin förbättrade egenvård kan vara värdefull för att bättre förstå vad som behöver hända för att det ska ske en förflyttning mot en bättre hälsa.
Syftet var att beskriva innebörden av ett upplevt förbättrat munhälso¬relaterat beteende sett utifrån ett patientperspektiv.
Studiepopulation & metod: Deskriptiv fenomenologisk metod (Giorgi) valdes för insamling och analys av data.

Systemanalys flingtork : Produktionseffektivisering
BillerudKorsnäs is a leading global provider of primary fiber-based packaging materials and on Gruvöns Bruk in Grums, they have chosen to invest millions in the boiler at the facility to increase the total capacity of the factory. This results in the Pulp Flash Dryer at Gruvön being burden more, which makes it important that it is of great reliability and can be run with a high capacity. The reliability of the Pulp Flash Dryer at Gruvön is not as good as one could hope, which leads to reduced availability and production, as well as to increased maintenance costs. There are a number of different reasons for this, but all the casual links are not known.The purpose of this project was to perform a system analysis of the Pulp Flash Dryer to identify bottlenecks and the most critical parts from a capacity- and availability perspective. Appropriate methodology for the system analysis was used and would be used in a structured way to perform the analysis with data from the process and the maintenance system.
Revisorns roll i nystartade företag
I den allmänna debatten om revisorer diskuteras bl.a. revisorns oberoende och hur det kan påverkas av revisorns roller som rådgivare till och granskare av ett företag. Vi ville undersöka inom vilka områden revisorn bidrar med rådgivning och få en uppfattning om hur detta eventuellt kunde påverka oberoendet mellan revisorn och ett nystartat företag. Vi valde att undersöka nystartade företag då vi inte funnit några tidigare studier på just den här kombinationen, revisor/nystartat företag.I vårt syfte att undersöka revisorns roll i nystartade företag har vi tagit reda på de vanligaste problemområdena, som nystartade företag upplever, och i vilken mån revisorerna hjälpt till som rådgivare. Undersökningen genomfördes med hjälp av intervjuer där respondenterna bestod av tre revisorer och ägarna till tre nystartade företag.
Bonusföräldraskapets många ansikten : en kvalitativ studie av roller och rollskapandet bland bonusföräldrar
The aim of our study is to examine stepparents´experiences of their role in the new family, we also want to examine if the role as stepparent is affected to the role as a biological parent. Our study is based on six semi-structured interviews, with three stepmothers and three stepfathers.By using role theory and symbolic interactionism our results indicate the requirement of constant negotiation as well as acknowledging the need to consider the other familymembers, those you may not have chosen to live with.We can see that the division of responsibility is governed by what is best for the family - to make life as easy as possible. It is clear that many stepparent lack guidance in what is expected of them in their new role; howeverr, they have been able to grow into it. .
Kostnader vid gallring med flerträdshanterande aggregat, från skog till industri
Profit in first commercial thinnings of today is hard to achieve. This is because of prevailing pulpwood prices and because of high costs of logging and transport. To reduce these costs higher productivity is advocated. One way to increase the productivity is the use of multi-tree handling harvester heads. The aim of this study was to calculate logging and transport costs in first thinnings, where multi-tree handling has been used.
Effekt av spädningsvätska på spermiemembranintegritet analyserad med NucleoCounter SP-100 :
This study is a part of a larger project where the aim has been to evaluate different methods to assure the quality in stallion semen, due to the fact that some stallions in horse breeding have poor semen quality. The increased use of transport semen requires new methods to ensure good semen quality.
In this part of the project the viability and concentration in fresh and cooled semen was examined with NucleoCounter SP-100. A comparison between two different commercially available semen extenders, Kenney?s and INRA 96, was made.
Utökade tillämpningsmöjligheter för turbinlösning i våtpartiet hos tissuemaskiner : Konceptförslag som möjliggör tillämpning av turbinlösning för maskiner vars banbredd är bredare än 2,9 meter
AbstractThis thesis is the final part of the Innovation and Design Engineering Programme (180 ECTS credits)at the Faculty of Health, Nature and Engineering Science at Karlstad University. The extent of thisthesis is 22.5 ECTS credits and has been performed independently by Hannes Jernberg during thespring of 2013. Metso Paper Karlstad AB is the task maker of this project, and Arvid Johansson is thecompany Representative. Metso Paper Karlstad AB is one of the world leading developer andmanufacturer of tissue paper machines.In the current situation, the company has developed and patented a power management systembased on a Cross Flow Turbine. The current construction is limited to a paper width of 2.9 meters.The company wants to take advantage of all the opportunities provided by the patents, to develop aturbine solution paper machine with a paper width that is wider than 5.5 meters, and give the abilityto manufacture paper for lower energy consumption which is an important part of the production asit is very energy intensive.Problems arise with the increasing length of the turbine, ultimately resulting in that the deflectionbecomes too big and that the momentums, due to the increased torque the turbine blades breaks.By applying the design process, this work has resulted in a number of potential solutions to theproblem.
Förbättrad vakuumtätning mot kabeln under plastextruderingsprocessen
This thesis is about developing a design that provides improved vacuum seal between a lead coating and a plastic coating during plastic extrusion processes of cables. This report is a part of the course MSGC 17 for Bachelor Engineers in mechanical engineering.The work is performed at Nexans Norway AS in Halden where they have a production of high voltage cables for sea-, and offshore industry. A problem they face is that they do not get enough good seal at the attachment to the plastic extrusion machine. They want to achieve a vacuum between a lead coating on the cable and a plastic coating of the cable for plastic extrusion, which is something they do not achieve today. The thesis is thus to come up with a design that provides better sealing against the cable.The work involves a construction part with the phases of product development processes.

Flexibla fixturer i bearbetande maskiner
This thesis was conducted at Linköping University and Saab Aerostructures DPS, Linköping, and focuses on the possibilities of flexible fixturing in machining applications. The thesis is part of the research project "Koofix", which is collaboration between Linköping University and a number of companies.The thesis is aimed towards small batch production which, for Saab Aerostructures DPS, means diverse part geometry and that parts are manufactured in very small numbers, sometimes just one piece. The result of this is that expensive dedicated fixtures are made for most parts. By introducing more flexible fixturing methods to this kind of production the cost of fixtures and tooling will be reduced, and make the production more efficient.New flexible fixturing methods has been presented and evaluated through the thesis, which has resulted in three different concepts. These concepts have been the result of literature screening and study of current manufacturing process at Saab Aerostructures DPS.
