24 years have passed since the Chernobyl accident when radionuclides were spread over largeareas of Europe, including the Scandinavian countries. Today, measurable activities of 137Csare still observed in many Swedish ecosystems.Ants (belonging to the order Hymenoptera) are social insects which collect organic materialfrom a large area around their nests. This study focuses on the 137Cs activity in ant nests andthe cesium accumulation in these nests. The aims were (1) to estimate the 137Cs fall-out in1986, (2) estimate the radiation exposure of ants and (3) find how 137Cs is distributed in an anthill. Seven ant hills (occupied by the species Formica polyctena) were studied near the villageof Hille, situated north of the city of Gävle in central Sweden.

The purpose of this study was to investigate the relationship between Health Locus of Control, Exercise habits, Food habits and Self-esteem (Personal self and Physical self) between two groups of student teachers at a university in the south of Sweden. Is health such as exercise, eating and self-esteem something that is controlled by internal or external factors? Student teachers that participated in Physical and Health programme and student teachers that participeted in other programme were investigeted. The participants (N = 160) answered the questionnaire. The Health Locus of Control scale and Tennessee Self-Concept Scale were used.

When models are used to describe physical phenomenon during development or modification of a technical system, it is often possible to reduce both the time needed and the overall development cost. With the use of models it is also possible to investigate the potential of the selected solution, without the need for any expensive details and testrigs. In many cases it is also not possible to test all the aspects regarding the functionality that are desired from the system, without using the complete and final product.In this case a model based approach has been used to optimize the different parameters in the new snubbing mechanism for the Nose Landing Gear Retract Actuator on the JAS39 Gripen.During the simulations, upper and lower boundaries were calculated for the length of the spring and the diameter for the restrictor. The governing constraints were given by the requirements for the retraction time during cold conditions and that the amplitude of the alternating loads in the uplock mechanism were brought to an acceptable level.The most promising results from the simulations were then used in a limited number of trials in the hydraulic rig to verify that the configurations comply with the requirements.The final parameters for the snubbing mechanism were chosen to 35±1mm for the spring and 0.4-0.5 mm diameter for the restrictor..

AbstractThe Swedish society has always been monolingual, but has for the past decades transformed into a multicultural and multilingual society. The aim of this study is to investigate if and in that case how preschool teachers work with language development in bilingual and multicultural preschools. The concept of linguistic and cultural diversity includes several different components, not least the social interactions that are of great importance to every individual's development, learning and participation in the world. By understanding the importance of language, language development and the role of mother tongue in second language acquisition, we look into various researches done concerning the effects of the preschool teachers? opinions, methods used to language developmental primarily for children who are multilingual and how the physical environment is shaped to promote language in multicultural and multilingual preschools.The method used in this study is semi-structured interviews with preschool teacher working in multicultural or bilingual preschool settings.

The purpose of the study was based on scientific literature to describe the quality of life of persons who have undergone a total hip replacement. The method was a descriptive literature review. The results showed that pain was the most obvious change after surgery. Mild pain before surgery was strongly associated with mild pain after surgery. But despite less pain were experienced early, it took 1 year to achieve the full benefits of improved physical function.

Knowledge organization is perceived as a central, constituting activity defining the notion of libraries. Critique calling for a new theoretical foundation voiced by active researchers within library and information science concerning the current knowledge organization has been utilized as a point of departure. Specifications concerning a new theoretical foundation implied by these critiques are considered within this thesis and theory found in The Order of Things by Michel Foucault proposed as an alternative theory for understanding knowledge organization as a human science where meaning, value and representation, by which the ordering of things is possible, is acknowledged as a result of human activity and history. Thus meaning, value and representation must be perceived as dynamic. An example of implementation of the proposed theory has been achieved by the use of bibliometrics.

With the technological development of the last decades, an increasing number of genealogists are carrying out their research online. The purpose of this master?s thesis is to examine how and why genealogists' information behavior has been influenced by the use of online services for genealogy. Using a conceptual model of genealogists' information behavior as theoretical basis for the study, I examine how the use of online services affect genealogists? search process, what information they are looking for and what information resources they use.

Syfte: Syftet med denna litteraturstudie var att genom en litteraturgranskning undersöka om ökad fysisk aktivitet har något samband med inlärningen och skolprestationerna hos barn i åldrarna 6-12 år. Metod: Litteratursökningen i databaserna CINAHL och Academic Search Elite resulterade i 15 artiklar som publicerats de senaste fem åren. Artiklarna har kvalitetsgranskats och därefter sammanställts. Resultat: Fysisk aktivitet i samband med inlärning har i ett flertal studier visat sig leda till positiva resultat genom snabbare svarstid, noggrannhet och uppmärksamhet. Barnen som deltog i aeroba aktiviteter blev mer uthålliga och kunde behålla fokus längre vid de kognitiva testerna.

This essay examines middle school students? understanding of a text read aloud to them in English and the connection between the degree of listening comprehension and the expected increase of vocabulary throughout middle school. The same listening comprehension test was carried out in grades 4, 5 and 6 in a middle school in order to survey differences in English listening comprehension in regard to the ability to reproduce the content of an oral text. The result shows that there was a progression from level to level when it comes to comprehension and the number of words reproduced and that this progression was most noticeable between grades 4 and 5..

The title: ?Klara färdiga GÅ? can be translated as ?Ready steady GO?, and is ment as a request to start move. In this project I want to invite people to walk more by creating creative, demanding and playful walkways and paths, where the body can be allowed to work just a tiny bit harder.It?s because walking means exercise and fresh air, for free and without spetial equipment. Walking can also be fun, it allows people to stop, change direction and experience things.I think activity should be fun, inspired by children playground my project is a contribution to how adults might stay healthier in a city, where too often healthy activity is solely confined to the gym or sports fields.

The intention of this study is to perform a content analysis based on a theoretical framework founded on multi-level governance, MLG. The thesis examines the formal changes within employment politics between 1999 and 2004 (Sweden´s action plan for employment) and 1998 and 2007 (the spring budget proposition). I will investigate how multi-level governance has effected the Swedish employment politics. Furthermore, the purpose of the thesis and the questions under consideration are: How have the formal structures within Swedish employment politics changed since Sweden?s admission to the European union, particularly during the periods 1997-2008 and 1999-2004? And: How do the changes in Sweden, together with the European union directive concerning employment, coincide in the so-called employment strategy?While performing the analysis I have focused on multi-level governance.

The purpose of this paper is to explore how practicing teachers have included their education in their teaching profession. The five teachers who were interviewed expressed that they lack experience in dealing with administrative issues, conflict management, parental contact and how to manage stress. There has been prior research on how teachers perceive their everyday working lives. Those results showed that teachers are becoming stressed by not knowing how to handle certain situations.My results showed that the teachers were to busy so they created their own methods on how to deal with phenomena that the education have not treated or discussed. The interviews were analyzed with the help of two constructivist concept, authenticity and activity .Authenticity focuses on knowledge is created and constructed by everyday situations.

Oxochlorates are anions with a partially naturally occurrence in nature but are also spread by human activities, including the paper industry. These compounds are harmful to both nature and humans, which makes it necessary to find a good way for their degradation. There are two different kinds of bacteria that can use oxochlorates as electron acceptors in their metabolism, bacteria that break down perchlorate and bacteria that break down both perchlorate and chlorate. A bacterium that can break down chlorate under anaerobic conditions is Ideonella dechloratans which holds the genes for chlorite dismutase and chlorate reductase which are enzymes for the degradation of chlorate. Gene expression and enzyme activity of chlorite dismutase are induced under anaerobic conditions, which makes it interesting to find out how this regulation functions in order to better exploit these bacteria in biological wastewater treatment.

The goal with this study have been to investigate how teachers in physical education perceive health as a concept, and how they choose to work with in the classes they teach. Health as a concept can be somewhat diffuse and as the Swedish curriculum doesn?t define the concept the teacher are given a freedom in interpreting what health is and how it will be taught to the students. This makes it interesting to study if teachers perceive health differently and if that affect what they are teaching their students.I used interviews as a method to answer my questions and the results show that there wasn?t much difference between the teachers in how they perceive health and how, and what, they teach their students.

This thesis is about a language-stimulating activity, called the Book Teddy, which take placein Markaryd, a small municipality in southern Sweden. The activity is described and someexamples given of the Book Teddy's visits to the homes of parents and their preschool children.Similar activities in Värnamo, Kumla and Borås, which have been inspired by the BookTeddy are also described.Facts about children's psychology, language development and child language illustrate theimportance of stimulating language acquisition in the early years. An important example is"The Bristol Study", a longitudinal study of preschool children.A questionnaire was sent to 93 parents, whose children were bom in 1991. 53 parents or57% answered. The analysis was made out of these 53 questionnaires.
