In Sweden there are 1894 small-scale hydropower plants in operation, which together generate 4.3 TWh of electricity per year according to Swedish hydropower compound (SVKF, 2011). This corresponds to the annual consumption of about 860,000 Swedish households (based on an annual consumption of 5000 kWh). In the mid-1950s there were around 4000 small-scale hydropower plants in operation in Sweden before cheap fossil fuels and uranium competed with them, in the current situation only 1,894 of these are in use. If slumbering small hydropower plants once again would be taken into use and some new ones are built, we would be able to extract about 7 TWh of renewable electricity from these annually in Sweden, representing about 1.4 million households.The thesis intends to calculate and construct a hydroelectric power plant at the existing dam in Olofsfors and give suggestions on how the power station should run during the time that fish migration is greatest in Leduån.The turbine and generator to the station in Leduån at Olofsfors is designed by the height of the fall and the water flow through the dam. The turbine selected for the station is a CK-1000RM turbine with a 4-pole 250 kW generator from Cargo & power turbine Sweden AB, which is expected to deliver 1.2 GWh per year.

The Church of Sweden has in recent years offered activities such as Christian deep medita-tion, mindfulness and health days. This may be a way for the Church of Sweden to reach the modern man who would not otherwise have come to the church, but there are critics who argue that new spirituality has made its entry in the Church of Sweden. The phenomenon of Christian deep meditation has become increasingly common in the Church of Sweden. In order to satisfy my curiosity about what a Christian deep meditation is, I decided to write an essay about this. My question is as follows: How important is Christian deep meditation as a religious practice in the Church of Sweden? This essay is a qualitative study and I have cho-sen to perform eight pieces of interviews, two of them are recorded.

Background: Sweden is a country where vitamin D deficiency seems to be common, partly because of its geographical position, which reduces the availability of UVB radiation, but also that people avoid sunlight due to increased skin cancer risk. Research shows that vitamin D plays an important role in the prevention of many diseases such as cancer as well as autoimmune and neuropsychiatric diseases.Vitamin D is a fat soluble pre-hormone and a collective name for closely related compounds which act as hormones after undergoing a transformation in the body.Humans can utilize vitamin D through diet and produce it in the body by exposing the skin to the sun. Previous observational studies and epidemiological studies have established a hypothesis that there seems to be an association between vitamin D supplementation and reduction of depressive symptoms.Objective: The aim of this study was to investigate if vitamin D supplements may decrease depressive symptoms.Methods: This work is organized as a literature review and article search is made in the database PubMed in January 2012. Keywords used were ?vitamin D and depression? and inclusion criteria were: randomized clinical trials, be conducted on humans, written in English.

In the forest sector, non-industrial private forest (NIPF) owners commonly interact with numerous stakeholders (e.g. forest managers, timber buyers, harvesting contractors and advisors) for counseling, planning, selling and hiring. Forest management is therefore built and influenced by the relationships between NIPF owners and other stakeholders. In the local context of a Southern Sweden, the Swedish Forest Agency (SFA) and the Southern Forest Owners Association (SÖDRA) are very influential stakeholders in small-scale forest management. Based on qualitative interviews and by means of grounded theory, an analysis of the relationships between NIPF owners and the mentioned organizations was carried out in order to understand the social context at the genesis of forest management decisions.

Syftet var att undersöka skillnader mellan olika studentgrupper uppdelat efter år av arbetslivserfarenhet och ålder. Detta för att se om arbetslivserfarenhet och ålder hade någon betydelse för studenters interna motivation, externa motivation, amotivation och kontrollokus. I tvärsnittsstudien deltog 71 studenter (60 kvinnor och 11 män) från en högskola i Mellansverige och deltagarnas ålderspridning var 19-47 år. Undersökningen byggde på två enkäter; The Academic motivation scale (AMS-C28) for college students (Ryan & Deci, 2000) och Academic locus of control scale for college students (ALC) (Trice, 2013). Statistiskt signifikant skillnad fanns mellan en studentgrupp som var 19-22 år gamla och en studentgrupp som var 26 år och äldre på kontrollokus, där resultatet visade att den äldsta gruppen upplevde mer externt kontrollokus än den yngre gruppen.

This study was made to compare and distinguish any differences in olfactory recognition and host plant adaptation between two strains of cotton leaf worm, Spodoptera littoralis. The populations used were established in Egypt and Benin, Africa. The documentation consisted of information about (1) each of the strains development through the larval stage up to pupation on diets of cotton, clover and cowpea. (2) Their oviposition preferences as adults between cotton, clover, cowpea, maize and cabbage. (3) Electroantennographic recordings to quantify any possible responses to plant volatiles. Throughout the diet experiments the larvae from the Benin strain showed significantly a better development between artificial, clover, cowpea and cotton respectively, while the Egypt strain had significance between artificial, cotton and cowpea/clover as diet. Also noted was how the strains substantial development of weight differentiated if fed the cotton diet, followed by the cowpea diet showing that the Benin strain would develop a higher body mass on a cotton diet as well as on a cowpea diet. This trend was however switched once the pupal stage was reached, where the Egyptian strain contained a significantly greater body mass than the Benin strain on the artificial and the Benin strain a greater on cowpea, which suggests that in the end, the Benin strain develops significantly better on cowpea while the Egypt strain develops better on an artificial diet. During the oviposition experiment that both stains showed a clear difference in hierarchy of host plants considered suitable for oviposition, where the Egyptian strain is significantly more attracted to clover than the Benin strain. Also showed with electroantennographic recordings and significant values was the higher sensitivity the Egypt strain had towards (E)2-hexenal, (E/Z)-b-ocimene, (Z)-3-hexenyl acetate, Nonanal, (-)-linalool and ?-myrcene when compared to the responses from the Benin strain..

Med utgångspunkt i George Lakoff och Mark Johnsons teori om den konceptuella metaforen analyseras i denna uppsats bildspråket i opionsjournalistiska texter som behandlar frågan om individualiserad föräldraförsäkring. Därtill anläggs med hjälp av Yvonne Hirdmans teori om genussystemet ett genuserspektiv, för att undersöka om metaforerna är könade och/eller reproducerar det binära könstänkandet. Materialet är hämtat från DN, Aftonbladet, Expressen och SvD under perioden januari 2010-novmeber 2013. .

This essay is an attempt to give indications of how pupils in the ninth grade value the arts subjects in Swedish schools. We believe that the subjects in arts education is mainly seen as ?fun? subjects rather than ?important? or ?useful?. However, this is not an attempt to find out the pupils view in a national scale, but instead an attempt to show what pupils may think and how this may affect the art subjects value..

This paper deals with a taphonomic study of contexts with osteological material of dog (C. familiaris L.) from the Mesolithic and Neolithic of Sweden and Zealand, Denmark. The general aim is to develop and test a method to try to understand the activity behind and define specific archaeological structures. My questions also regards to wether a taphonomic analysis of the material could be used to identify treatments as wrapping and contraction of the dogs, but also dismembering and other preparations of the body. The study focuses on the relation between the space of decomposition, disarti-culation of the joints, evidence of wall effect, cutmarks, weathering and signs of postdepositional arrangements.The analysis is based on contexts from the materials Hornborgasjön, Vedbæk, Skateholm I and II, Sjöholmen, Ertebølle, Bökeberg, Bredasten, Löddesborg, Bergsvägen and Röekillorna, dating from early Maglemose culture to Neolithic Battle axe culture.The analysis shows that a closer study of taphonomic processes can be used to identify different structures as graves, offerings, religious and non religious contexts or parts of animals, probably put into the ground as waste.

Hopp och Självkänsla är två begrepp som studerats länge inom positiv psykologi och Hoppteorin av Snyder och kollegor (1991) förklarade hur egenskaperna hänger ihop. Hopp är ett begrepp inom kognitiv motivationsteori och definieras som den generella upplevelsen att ens mål går att uppnå medan Självkänsla är upplevelsen av det egna värdet. Hopp består av två komponenter:Agency och Pathway. Pathway är vägfinnande tänkande och Agency den motiverande komponenten. Föreliggande studie syftade till att undersöka sambandet mellan Hopp samt Hopps två komponenter med Självkänsla.

According to old european tradition the ideal national state has a unified people, but in reality practically all states has one of several minorities that to a smaller or greater degree differs from the majority. One such minority that have been present in many countries and managed to avoid becoming completly assimilated are the jewish people. Their dream of a state of their own eventually lead to the founding of the state of Israel where they themselves are now in majority. The purpose of this report is to study how the jews historic experiances has affected the political parties in Israel, how they choose to meet the ?challenge? of their own minorities och whatever they treat different minorites differently.

With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods. The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute. 2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.

Since prehistoric time man has used wood to build their environment. The material?s availabilitycombined with its good mechanical properties has often made it the material of choice. Like allmaterials exposed to natures degradative processes the properties of wood decreases over time.Rot, UV radiation and attacks by insects and pests damage wood if not protected. Since we wantwhat we build to consist, optimizing our building materials durability is of great interest.Techniques and methods for increasing the endurance of wood have been developed in severaldifferent places and for a long time.

The aim has been to see if physical education (PE) is more an arena for bullying than swedish language education, in a swedish urban school. Furthermore to get an insight in the students sense of exposure to bullying in the locker room and during PE class. In the purpose is also included to analyse the answers in a gender perspective.Questions are: Is PE to wider extent an arena for bullying compared to swedish language education? Is the students? opinion that they feel worried about being and changing clothes in the locker room due to other students bad intentions? Do the students think that boys and girls bully in different ways?The method used is a questionnaire answered by 69 students in seventh and eighth grade in Åsö compulsory school. Furthermore, interviews has been made with a boy, a girl at the school and a teacher in PE to get a deeper insight above the questionnaire.Results of the study showed that the students to a wide extent, 100 % of the girls (g) and 89 % of the boys (b) thought that bullying can look different between PE and swedish language class.
