Trenden i byggbranschen är att efterfrågan på täta, energisnåla byggnader ökar. Passivhus och andra lågenergikonstruktioner blir vanligare och vanligare. Riskerna med att bygga in organiskt material som trä i dessa konstruktioner har fått branschen att börja titta på alternativa material. Lättbetong är ett material som både har bärande och isolerande egenskaper. Dessutom är det inte organiskt vilket gör det okänsligt för mikrobiell påväxt.

The purpose of this study is to find out teachers view on manipulatives as a way to concretize a certain mathematical content and to highlight knowledge and experiences within the range of using manipulatives to concretize. By answering the questions below different approaches a teacher may have towards the manipulatives and how that may impact on student?s learning will also be discussed in comparison to mainly traditional and socially constructive theories of learning.What is the teachers view on manipulatives as a way to concretize?What purpose do they have when using manipulatives?According to the teachers, what does it mean to concretize a certain mathematical content?According to the teachers, what connection is there between manipulatives and concretizing?Through interviews and observations conclusions can be made that the teachers are in general positive towards using manipulatives as a way to concretize a certain mathematical content although the definition of what a manipulative is differ somewhat between the teachers. The teachers working with manipulatives do it in a well thought out fashion but more research is needed to furthermore define the purpose of using manipulatives. Few countries spend so much time concretizing and working with manipulatives as Sweden do, but still Sweden score below the OECD-average on the mathematical PISA-tests.

Background: What is a share and what determines the value of a company? This is a constant issue that many in the financial world are facing. Many argue that there has been some decoupling between stock valuation and how the company in question is developing operationally after the financial crisis that the world faced during 2008-2009.Problem: It is important to distinguish between the company and the share. A company that is good and well maintained may not be worth buying only because of it. The share is judged by other elements also.

The county of Dalarna is at present carrying through a process of digitalization where traditional x-ray film is being replaced with digital detectors. Earlier used methods for dose optimization turned out not being sufficient. This report presents a method to harmonize dose levels between x- ray sites equipped with Fujifilm imaging plate systems. An exposure index, S, related to the dose level of the examination is computed to every x-ray image. S turned out to be inversely proportional to the detector dose used at the examination.

The purpose of this investigation is to see if there is any difference in how long pupils are staying in the activity of the music- and culture schools in the country. I have compared this with how large the teachers engagements are in average at each school, how many teachers each school holds and if one teacher is teaching within different areas, e.g. on different instruments. Thru mail contact with the headmasters at the music- and culture schools I have gathered data concerning the length of which the pupils are staying at the schools, the number of teachers at each school, the size of the teachers services and in how many different areas each teacher is teaching.It has been hard to get to any results in the investigation since the music- and culture schools don?t compile statistics on how long their pupils are staying at their schools.

Background: First Line Managers are expected to create a health promoting work environment. Research has shown that the prerequisites for accomplishing a health promoting leadership are not always the best. Aim: The aim was to elucidate the prerequisites for a health promoting leadership as First Line Manager at a University hospital in Sweden based on competence, role, support structures and own durability. Results: First Line Managers at the chosen hospital seems to have rather good conditions for conducting a health promoting leadership. All respondents did have a university degree and most thought that their competence corresponded well with the role.

Sveriges skogsindustri är beroende av skogsmaskinentreprenörer för råvaruanskaffning. För att trygga försörjningen till industrierna, effektivisera och förbättra drivningstjänsterna är det viktigt att företagen i branschen är lönsamma. Syftet med den här studien är att identifiera hur lönsamma skogsmaskinentreprenörer i Götaland arbetar för att uppnå goda ekonomiska resultat. Med hjälp av gränsvärden för nyckeltalen avkastning på eget kapital, avkastning på totalt kapital, soliditet, nettomarginal och kassalikviditet identifierades de mest lönsamma skogsmaskinentreprenörerna. I en kvalitativ intervjustudie intervjuades företagarna om hur de arbetade med att leda sina företag, vad de ansåg vara den viktigaste framgångsfaktorn och deras syn på möjligheter till ökad lönsamhet. Tillsammans med tidigare studier formulerades faktorer och förbättringsområden som påverkar skogsmaskinentreprenörernas lönsamhet.

The aim of this study about wind power planning in forest was to examine the factors and restrictions, which represent technical limitations, biodiversity, tourism and amount of energy for wind farms in Kronoberg County. Suitable areas for wind power were identified from the collected information about planning principles and potential conflicts. From the suitable areas the potential energy gain is calculated. Methods used were mainly a literature review, interviews with experts and practitioners, GIS analysis and a rough calculation of the energy gain. The section of information and facts describes in general wind power planning and possible conflicts.

In this study I analysed how burning affects sprouting ability and survival of oak (Quercus robur) during the first season after a burn in southern Sweden. The study consisted of two separate field tests; in the first, two 300 m2- plots in western oak dominated forest were burned to analyze the fire behavior and the immediate mortality of oak and beech seedlings defined as individuals (> 20cm of height). At the end of the season almost 50% of the oak seedlings had resprouted while the beech seedlings had 100% mortality. An attempt to investigate the effect of the burn of artificially sown acorns was totally ruined by wild boar grouting before any conclusive results could be seen. In the second test the resprouting ability of oaks of varying diameters (average BHD 7-9 cm, range 2-42 cm) was examined one season after a prescribed burn in southeastern Sweden.

The paper aims to examine how well a small group unaccompanied children have established themselves in Swedish society. In order to determine how well they have established the empirical material which is primarily based on quantitative data has been measured with a theoretical model developed by the theorists Nancy Fraser and Alistair Ager and Alison Strang. Based on the theoretical framework the unaccompanied children establishments have been measured in example income, education, debts with Kronofogdemyndigheten and social network. It was found that the unaccompanied children had not achieved the establishment in the society that was expected from the theoretical framework. Their results were also generally below the national average for young adults in Sweden who are the same age.

In the media richness of everyday life, the encounter with information graphics ishappening on a daily basis, whether we are aware or not. With the development andeasy access of technologies, new ways to create and display information graphics hasemerged. Among them, the animated information graphics, which in the few pastyears appears to have increased in popularity on video sharing websites such asVimeo and Youtube. In the genre of animated information graphics, there seems to bean inherent diversity regarding the design characteristics. In this study we exploredliterature and research on information graphics and related subjects.

The Swedish agriculture has gone through some changes and there are more changes coming in the near future. The structure is mowing towards bigger units. The average age for the Swedish farmer is high, and a great number of agricultural enterprises are going to get an owner from the next generation within the family. The aim of this thesis is through case studies examine the economic consequences of transfer of agricultural holdings. The methods in change of generation that this essay treats are changes of generation, in the form of gift and purchases.

There are some students who leave their studies. How can this be explained? Are present day high school students satisfied with their choice of school or the courses they have chosen? How did they decide what to study in upper secondary school? The main focus of this study is to examine the factors that influence the decision making of young people when it comes to choosing schools, their educational ambitions, and finally their focus on grades in Upper secondary school.   The study is based on the quantitative method, extracting its results through a poll conducted at an upper secondary school. The target audience of this poll was students that are completing their second year.  A statistical analysis of the results was carried out and the results were then presented by relevant diagrams.
