This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.

The purpose of this study is to find out how the four teachers at the two preschools believe they are working with gender and how they actually work with it in practice. It also aims to show how they treat the children at the preschool based on their gender.What is the preschool teachers view on gender and equality?How do they consider that they work with gender and gender equality, and how do they really work with it in practice?The study is based on a qualitative study were I chose to both interview and observe four preschool teachers from two different preschools. My theoretical starting point is Yvonne Hirdmans theory of gender and also research on gender equality. The results show that the majority of respondents believed that gender and gender equality means almost the same thing or have the same meaning.

The purpose of this paper is to create increased understanding of how pupils learn statistics. This includes gaining insight into pupils' use of their own experience and group experience to help to get a better understanding of statistical problem solving. The study's research questions are about how pupils learn to work with data in tables and diagram and how pupils learn to work with measures.The theoretical framework consists of two approaches to studying learning. One approach is based on pupils? cognitive conditions, called set-befores, and the pupils' previous experiences, called met-befores.

The break up of the family unit leads to new living arrangements and significant changes for children. This can be an extremely upsetting experience for a child, especially if the child is old enough to understand what is happening. New living arrangements can effect a childs fundamental sense of security as well as having consequences later on in life. The object of this research paper was to examine how a group of seven people (children from split families who are now adults), interpreted and described their childhood in relation to the living arrangements they grew up with after the breakdown of the family unit. The main question areas we have examined are: How have the interviewee's living arrangements during childhood affected their understanding of themselves today? In what way has the adult's present day lifestyle been influenced by the split up of the family that they grew up with - using their own words? How do the children from split families describe and interpret concepts such as family and marriage, based on their own experiences? Our research was conducted with the help of seven people from split families who are now adults and who experienced different types of split family arrangements as a child ? permanent residence with mother/father or alternate living with both parents.

Teaching preschool children about the environment. A comparative study of how two preschools work with environmental issues.My investigations are based on qualitative interviews and observations carried out at two preschools, one of which has a nature and environment profile while the other works in traditional ways with these questions. I sought to explore the ways in which pedagogues in each preschool raise environmental awareness and, more generally, awaken an interest in nature in the children. The consequences of methodological similarities and differences will be considered.This term paper concludes that the difference between an environmental profile preschool and a traditional preschool working on environmental awareness is not large. The knowledge gained by children in the latter preschool surpassed that gained in the former.

The purpose with this report is to give structure to the storage area betweenproduction and packaging at Spaljisten AB in Åseda.

They will manage this by installing a new automated packing line andincrease the efficiency of the old manual one. The theoretical background ismostly obtained from literature which contains relevant facts for our report.The storage area has been studied visually in order to search for improvements oftoday?s layout.

Quality is the key to a well executed product or service. The construction industry hasn?t highlighted the quality in recent times which have contributed to the construction industry receiving much criticism in the field. The public sees it as an offhanded industry where errors and delays are common.The reason for this is considered to be primarily the lack of time, constant pressure to reduce costs and skills and the ability to communicate between the parties about what the correct quality really means. The industry has begun to realize that it must start setting clearer standards and that there are great opportunities for improvement.This report will give Peab an opportunity to develop their quality work.

By focusing on the spokespeople who appears in the articles we have made an attempt to answer questions regarding who was heard in the debate on gender-neutral marriage and how the homosexual couples are portrayed in relation to the above criteria.The collected material consists of 89 articles, published in 2009, in Swedish newspapers which have been analysed by using quantitative content analysis. Ten articles have also been selected for a critical discourse analysis based on Norman Fairclough?s approach.

This master thesis is performed at Scania Axles and Gearboxes, a production plant located in Södertälje. Within the plant axles, gearboxes as well as central gears are assembled from components to finished products. All production is conducted on production lines, with a pre-determined rate, which is supplied with components by the material handling department. Since the production quantity and the mix of product variants produced on the production line is customer order-based, the number and type of components needed for production as well as appropriate staffing within the material handling department is difficult to predict. Scania is currently using a number of different resource planning tools for each material handling-department within Axles and Gearboxes to visualize the workload within the departments.
