The aim of this thesis is to find a statistical model that sort logs according to a predicted modulus of elasticity on the sawn boards. The input parameters for the model are X-ray variables from an X-ray scanner. For some of the log classes sawn at the sawmill it is desirable to have a narrow distribution of modulus of elasticity on the sawn boards. 250 pine logs from five different diameter classes were numbered and followed through the sawmill process. Log data were collected from X-ray and 3-D scanners in the log intake.

Are we able to help younger students to develop their understanding and their use of the capital letter, dot and question mark by giving them intensive teaching on the subject during a short period, and would the effect be long lasting?I decided to investigate this together with young students in second and third grade and at the same time try to see which grade would benefit most.By using an experimental research design I conducted the investigation in a class with children from both grades where the result was compared with two similar control groups. The investigation lasted during five months, while the students were able to show their knowledge in the subject just before and after a two weeks period of intensive teaching and then again after four months.The result showed that the intensive teaching had an effect that lasted over time and that it was the students in second grade that would benefit most. .

AbstractBy finding out the pupils' choice of strategies for problem solving, we as teachers, can get a better understanding of their way of thinking, and thus also help them develop in their learning of mathematics. In a classroom environment where several different strategies could be found, the pupils' learning is facilitated as they, with the help of classmates, find positive and negative attributes of different kinds of strategies. The pupils are, in other words, each other's resources, rather than competitors. The main point is that the classroom environment, as well as the role of the teacher in the classroom, are both key elements for good mathematics learning.In order to increase the understanding of the pupils' choice of learning strategies, a survey was performed based on two school classes, one third grade and one six grade class at the same school. Both classes received the same mathematical problem to work with, and the strategies observed were analyzed and compared.

The lake Spexhultasjön is a moderate humic mesotrophic lake that is not acidified. The fish fauna was investigated by using a standard method for sampling freshwater fish with multi mesh gill nets. The fish fauna was diverse with perch, pike, tench, common whitefish, and roach. Perch and roach dominated. There were few pikes.

In this study, five qualitative interviews were conducted, four of those with pupils and one with a teacher, in grade 9. Humans - a gregarious creature written in the context of status and hierarchy, aims to study how these students in grade 9 are grouped and how you look at each other in and between these groups and also in terms of status between and within the group. Using the concepts of identity, adaption, exclusion and the meaning of emotions with the chosen theoretical concepts by Goffman and, Elias and Scotson the purpose of this study has been answered. The results showed that the students were quite flexible between the groups in their class; most of them were part of a small group that consisted of their ?close? friends.

The aim of this thesis is to examine how the history of mathematics can be used in teaching and whether pupils? attitudes to mathematics can be affected by this. In order to do this a school project about the history of mathematics is planned, implemented and analysed.The following questions are addressed:? Why use the history of mathematics in teaching?? How can the history of mathematics be used in teaching?? Can a historical perspective in teaching affect pupils? views on mathematics?The school curriculum emphasizes the importance of history in teaching. Literature, scientific articles and government inquiries call attention to the positive effects of including a historical perspective in teaching.The school project, which underlies this thesis, is put to practice by 25 pupils in a mathematics science profile class.

The main purpose of this report is a first step to cover the scarcely investigated subject of interspecific competition between roe deer, Capreolus capreolus, and fallow deer, Dama dama. The report focuses on the distance between individuals of roe and fallow in the study area as well as which factors that is affecting the variation in distance depending on fallow deer group size and changing population density over time and in two areas. For additional information the history of the populations, such as harvest and distribution, is also investigated. The report came to the conclusion that interspecific competition between the species do occur. The elevated distance between individuals of the two species is clearly significant. The most important factor affecting the distance seemed to be the size of the fallow groups.

This study was carried out in Ronneby municipality during May 2006. I chose to compare three senior schools with regards to the implementation of objective orientated directives based on the teachers understanding of the task, motivation, resources allocated and their significance for the disparity between boys? and girls? grades.I carried out nine in-depth interviews: three at each senior school. From the interviews it emerged that teachers perceive objectives differently from parents and students. Teachers claim that they understand the directives but say that they lack the resources.

Knowledge of ecological processes are a basis for the understanding of important environmental issues. Through qualitative interviews, 8 preschool class pupils have replied to questions concerning the concept nature, disintegration and environment. The aim of this survey was to examine what attitudes and knowledge children with different pedagogical background have about the nature and the environment.The result of this survey in whole demonstrates that all pupils have good and equivalent knowledge of the nature and the environment, independently of their different pedagogical backgrounds. A difference was however that children that have background from ?I Ur och Skur? (a Swedish outdoors preschool program) know the names of all small bugs that were in the survey.

The purpose of this essay is to find out how two schools work with newly arrived children and to see how they differ. There is a lack of national directives for those who work with newly arrived children and teenagers; this makes the introduction very different between schools.The study is qualitative, based on interviews with four teachers in two different compulsory schools. One school is situated in a suburb of Stockholm and the other one is situated in a minor community in Dalarna. One schools got a preparatory class for newly immigrated pupils and the other school doesn?t.The theoretical frame that I have chosen to analyse these interviews are literature and research on Bilingualism, Children with PTSD, Intercultural Pedagogy and Special PedagogyMy results also show that these schools work very differently, and that there is very little co-operation within the school and with the units around the school, regarding these children.

This paper is about the different parts within the officers training that motivate the cadets to continue their employment within the armed forces after graduation, it also brings up the different parts that influences their motivation in a negative way. Six cadets from the 2011 class at the military academy at Karlberg have been interview in order to give their view on the following seven themes; reasons to take employment, collegiate attitude, comfort, study motivation, perceived education quality, the regiment and career. The responses have then been compared to the previous research at a cadet level which have been scarce. The result followed the previous findings about conscript?s motivation to continue their career and officers to end theirs.

This essay is an investigation of the level- and importance of interactivity on YouTube for the active user. YouTube is a great example of a user-friendly Internet environment which enables the users to take part in a virtual community where they can create the content and, with the various functions the site has to offer, interact with each other. With Uses and Gratifications as a tool for this research we look at the motivations and needs of the user and how they come into play on the most popular video distribution site in the world today. Qualitative interviews on Swedish respondents give us insight in how the YouTube-users with their own words perceive this relatively new highly interactive era. We focus on a narrow group of the most popular age-group of YouTube-users to go deeper - not to expand.

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

This study concerns digital stories told by five young Romani students and one teacher from Roma Culture Class in Stockholm, Sweden. The theoretical framework draws from theories concerning identity, culture,Romanipe, the Romani value system and social semiotics. The material for the study is the digital stories that were analyzed qualitatively. The results show that the young Roma in the study demonstrate pride in their Romani background and culture, but also signs of changes and development in their culture. Some of the participants do not show external signs of Romani traditions, for example in the ways of dressing.
