Vidhäftning mellan prefabelement och pågjutningsbetong : Undersökning hur skrovligheten påverkar vidhäftningskapaciteten vid skjuvning

Self-compacting concrete has soon been around for a decade. Recently the prefabrication industry has started to use this fairly new concrete type in larger scales, mainly because of its distinctive properties.  There are still certain areas that need to be thoroughly examined, such as bond capacity. There have been very few studies regarding shear capacity due to the fact that the procedure is complicated.This report will highlight a method to examine the shear capacity of different surfaces that have been prewetted as well as non-prewetted surfaces. The surface areas follow BBK 04?s and Eurocode 2?s demand for surface roughness.  A smooth surface will be completed in order to confirm if the different shapes influence the bond strength by shear stress or not.                       The purpose of this essay is to measure the bond strength within the shear capacity as well as examine the impact it has on surface roughness and treatment for shear bond.The method used to identify the shear capacity is called L-shaped Push-Off Test.

Reaktionskrafter i dragarmarna på en traktors trepunktslyft : Teori och praktik

Tractors of today come equipped with a CAN-system. A CAN-system sends information from sensors to electronic control units who process the signals. The sensors measure several interesting parameters such as force, pressure and speed for various components of the tractor. This thesis discuss a force sensor which is placed in the pivot of the tractors three point linkage, the sensor measure the horizontal reaction force from the load that the tractor is exposed to. Signals from this sensor can be used to measure the force from any implement that the tractor is exposed to during an operation.

Vattenkvarnar - en studie om Hjul- och skvaltkvarnar och deras förekomst i Fulltofta socken

This rapport handles the presence of two kinds of watermills in the Swedish landscape. The first is a small type with a horizontal shovel blade and the other a bigger kind with a Vertical standing shovel scoop. The rapport seeks for information of their capacity and how long they existed as flour producing units. A important issue is how small can a brook be and still run a mill. Finally the reasons for their disappearance in one selected parish is shown..

Kraftanalys och framtagning av mätanordning för vertikala vindkraftverket Lucias bärarmar

The project contains a force analysis of the Vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.

Doktoranders förhållningssätt till Open Access: En studie av epistemiska kulturers betydelse för doktoranders tankar kring vetenskaplig publicering

The aim of this bachelor-thesis is to study how postgraduates approach open access during times of change within scholarly communication. Our theoretical framework is based upon Knorr Cetinas epistemic cultures and Cullen & Chawners theory that there is a paradigmatic conflict within scholarly communication due to the fact that open access has failed to reach the same level of prominence among researchers as it has within research libraries. We interviewed six postgraduates at Malmö högskola in order to find answers to our research questions. We identified a shared epistemic culture among the postgraduates, which can be explained by the fact that being postgraduates, they all share similar experiences and values. We chose to call this epistemic culture the horizontal epistemic culture.

Analys av lageregenskaper utifrån mätningar i testrigg

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: Hur styrs folkrörelsen?

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.

Kommunikation och samordning : En studie av internkommunikationen inom Region Värmland

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.

Film distribution and exhibition in the EU

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.

Småskalig utsädesproduktion : ekonomiska och organisatoriska aspekter

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.

Energihushållning och varsamhet för äldre byggnader : Chefsbostaden i Strömsholm, ett timmerhus från 1900-talets början

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.

137Cesium i myrsamhällen i Gävleborgs län 24 årefter Tjernobylolyckan

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.

Sambandet mellan hästens huvud/halsposition och ryttarens rörelse i sadeln :

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.

Urban building kv. domherren

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.
