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.

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.

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.

The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.

The notion of firms interacting with technology is not new; these types of systems were already in place in the mid eighties. E-business users worked with connections between their inbound logistics and procurement systems, and suppliers? order-entry systems. When these connections were described for the first time the vertical links between two, or more, value chains in a value system received more attention in firm strategy. The design of the linkages in the value system was said to be a product of the need for coordination and relative bargaining power.

A study has been performed that investigates the variation of iron content in groundwater.The study was initiated by Midvatten AB, which noticed that the iron content in groundwater samples can vary greatly over small distances. The purpose of this study was to geochemically and geohydrologically determine the factors that influence the content of iron and manganese in groundwater from a selection of eskers in Dalarna, and determine how to best sample groundwater with the method used by Midvatten AB. An evaluation was made of how the vertical variation in soil material, water composition, pumping time and pipe material affects the content of iron in groundwater. Piper diagrams were used to study the relationship between the chemical composition of the groundwater and the content of iron and manganese in groundwater samples from the studied areas. The groundwater from the studied areas was then classified in the Piper diagrams, according to the content of the major ions.

Syftet med rapporten är att utvärdera och jämföra två standarder, AATCC Test method 198-2011: Horizontal Wicking of Textiles och AATCC Test method 197-2011: Vertical Wicking of Textiles. Standarderna publicerades år 2011 av American Association of Textile Chemists and Colorists. Standarderna mäter wicking, det vill säga, med vilken hastighet som vätska transporteras genom textil, med en horisontell och en vertikal testmetod. Hastigheten anges i olika enheter beroende på standard, enheten för AATCC Test method 197-2011: Vertical Wicking of Textiles är mm/s och AATCC Test method 198-2011: Horizontal Wicking of Textiles anges i mm2/s. Skillnaden i enhet och mätmetod innebär att standarderna inte kan jämföras rakt av genom resultat och mätvärden mellan de båda standarderna.
