Vertical hydropower units has a rotating mass of up to 1000 tons. For the generator and turbine to work well the rotating system is required to be centered in relation to the surrounding structure. This is achieved by means of radial bearings. The dynamic characteristics of these bearings have a strong impact on the overall rotational dynamics of the total system and thus influence the vibrations in the unit. At Vattenfall Research & Development in Älvkarleby ongoing research is taking place on how the bearing parameters should be represented in the rotor dynamic calculations.

Riksteatern is a Swedish movement which was formed during the 1930s. The movement now consists of 230 local societies and had 545 000 visitors last year. The purpose of this thesis is to investigate how a movement, mainly financed by the Swedish government, is run. To be able to understand this, the theories of Pierre Bourdieu are used together with organizational theories. The empirics are collected mainly by semi-structured interviews made with employees at Riksteatern.

This paper deals with the subject internal communication. We received this assignment from Region Värmland, an organization formed jointly by the 16 municipalities in the county of Värmland, to take responsibility for regional development, growth issues, culture and adult education in Värmland. The organization consists of a number of geographically dispersed units with specialized working areas. In this type of organization, there are high demands on internal communication as a tool to coordinate the organization?s different units and integrate their work, in order to reach the common goals.

Training of zoo animals started when the first zoo opened in 1752. The difference between then and now is that from the beginning the zookeepers did not focus so much on animal welfare. Nowadays animal welfare is the most important thing in the training. Therefore, the zookeepers are training the animals mainly for veterinary purposes and activation. The training makes the animals less stresses during handling. When the zookeepers started to train elephants they used unpleasant stimuli such as a whip when the elephant did something wrong.

This paper examines the film distribution and exhibition sector in Europe. The general analysis of these sectors? situation was made. Moreover, the comparative and more in depth analysis of three countries by the Porter?s five forces model was made; These were United Kingdom, France and Denmark.

The economic situation in the Swedish agricultural industry is currently experiencing a development towards larger units. This progress occurs simultaneously as farmers in cooperation more frequently make investments to decrease risk exposure and to improve the financial result. The purpose with this thesis is to study which advantages and problems a group of farmers experience after a common investment in a small-scale seed production. The aim with this investment is to increase the level of vertical integration in their respective agricultural firms and the results will be analyzed from an economic point of view. At present, the farmers are all seed producers with considerable cultivation areas.

This report is the result of a degree project in building engineering, at an advanced level. The project evaluated a building from a technical and historical point of view, and focused on its energy consumption, particularly the energy used for heating. The building in question was a small apartment building in Strömsholm, Sweden. It was made in 1902, from vertical logs, a not so common form of the traditional log house. The goal of the project was to evaluate if the energy consumption could be reduced in accordance with building preservation regulations, that is without damaging any of the building?s cultural or historical values.The building was surveyed with the help of archive and literature studies, interviews and inspections.

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.

En hörselnedsättning är en kommunikationsstörning som starkt påverkar en bebis utveckling på många områden, inte bara ljudperception och talad kommunikation. I Sverige screenas idag alla bebisar redan på BB, för att så tidigt som möjligt upptäcka medfödda skador. Dessa metoder har dock informationsbegränsningar angående hörselnedsättningens grad och frekvensberoende. När bebisar är ett halvår gamla kan den observerande audiometriska metoden Visual Reinforcement Audiometry (VRA) användas för att utreda hörselnedsättningen. Metoden baseras på att en audionom gör en subjektiv bedömning om bebisen reagerar och vänder huvudet till följd av presenterade ljudstimuli med känt frekvensinnehåll och känd ljudtrycksnivå.

This thesis describes a conceptual design of a support frame for a synchronousgenerator used in a vertical axis wind power plant. In this system the generator isplaced on ground level. The thesis also considers the design of housing for thesupport frame and generator. The concept presented in this report is based on anearlier design. Besides geometric design, simplified simulations has been run in orderto optimize some of the parts included in the construction considering naturalfrequencies and structural strength.The result is presented as CAD-models andan assembly drawing..

Dressage schooling is not a subject that rests on science, it is a matter of dependable experience. So far there hasn?t been so much research about it, but more and more is done. Especially the interaction between rider and horse is a nearly uninvestigated field. Riding skills is much about having the right position, and having the horses head and neck in different positions, but there are no research done that support or deny that this old ?knowledge? is for the best for the horse. This study was performed to evaluate if the head and neck position of the horse, and the velocity, has any influence on the position of the rider.

At the beginning of 2011, Sweden started using the European rules for structural design, the Eurocodes, instead of the previous national rules. In both the previous rules and the Eurocodes, it is possible to dimension concrete columns using tabled values. However, the required cross section measurements have increased considerably. Moreover, it is possible to dimension concrete columns using calculations, however, this is unusual.The development of a fire in a fire cell can be divided into the growth stage, the fully developed fire and the cooling phase. The duration of each phase, as well as the temperature, is dependent on a number of factors, e.g.

Vertical village är ett tätt kvarter på östermalm med sammanlänkande trappor och gator som tar dig upp i stadsrummet,en förlängning av staden upp över takåsarna med vidsträckt utsikt. Längs din väg upp mellan gator och gränder nns livoch rörelse. För att skapa denna o-entlighet krävs en öppen byggnad med god förankring till marknivån men istället förett traditionellt kvarter med o-entlig verksamhet i markplan valde jag att lyfta det o-entliga rummet över takåsarna medutblick över staden. Detta skulle bli ett o-entligt rum på Östermalm som man söker sig till på samma sätt som observatorielundeneller söders höjder.I mitt projekt har jag valt att arbeta med två skalor, den mindre som blir det o-entliga stadsrummet medan bostäder ochkontor ger byggnaden sin höjd. Sett från staden ska byggnaden upplevas som en upphöjd fortsättning av gatan med enmindre skala som på ett spännande sätt bjuder in till detta stadsliv.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

In present time, more and more people move into cities. Densification of cities as planning policy together with an intensive urbanization, makes urban planners face with the contradictory task of creating a city that is both dense and green. Façade vegetation has been used for centuries, mainly in the form of various climbing plants that with or without supportive structures have spread over facades to give a green impression to the environment. The development of new technology today allows urban planners to use greenery integrated with façades. Vertical gardens offer a larger variety of plants, and at the same time takes advantage of the technological benefits of vegetation in city planning.
