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.

A study to optimize insulation thickness for stock-, industrial- and office-buildings for external walls and roof in an economical perspective has been conducted on behalf of DynaMate. DynaMate?s role is to maintain all Scania?s buildings. Analysis has also included other parts of the building envelope, such as windows, exterior doors and industrial doors. In this thesis, three different types of exterior wall constructions has been investigated, these are a sandwich design consisting of sheet metal and a another one consisting of concrete, as well as a wall of concrete with a coating of plasters.

AbstractClimate and environmental issues are of paramount importance. Researchers agreethat we must all contribute to a reduction of gases that contribute to climatechange. Energy consumption must decrease within all sectors and the promotionof renewable sources of energy must be introduced.Each sector should aspire to decrease its energy consumption. Energyconsumption is strongly linked to waste gases that contribute to climate change.Passive houses are a part of the construction industry's methods to attain energyconservation.Passive houses are derived from low energy houses and super insulated houses. Apassive house is intended to obtain heat from the inhabitants and through theiractivities.

The purpose of my task was to map the pallet flows at Findus and put together as well as analyze the problems. My work has also included finding out what alternatives there are to the present pallet exchange system and suggest measures to reduce the problems.The problems can be divided into poor quality and hygiene issues. The poor quality, for instance poor strength is due to arbitrary judgements and the fact that there are companies that make a system of manufacturing forged pallets of an inferior quality compared to the EUR-pallets. These pallets are marked with stamps more or less similar to the EUR-mark and taken into the exchange system. Of course there are rules how to judge a pallet but these rules are many and sometimes indistinct and there are a lot of marks to keep track of.The most dangerous part is when the pallets lack the prescribed carrying capacity.

This report presents suggestions and recommendations on how to convert an old industrial building, built in 1958, to an office hotel. One of the main criteria was that the floor plan should be flexible. The building is situated at Jonsereds Fabriker and the study was conducted for Hantverkslokaler i Göteborg AB, the estate owner.The survey is initiated with study visits at various office hotels, together with studies of literature regarding office planning. One conclusion from the study visits is that meeting-places, where the different companies can meet and exchange ideas and services, are important. Another one, and probably the most important parameter when planning offices is that they should have windows.

International Marine Group, IMG AB, was established in year 2000, and became the parent company of the three sister companies, Momec AB, Isolamin AB and Premec AB. The IMG ? group supplies complete marine/offshore interior accommodation and tailor-made system supplies to the Building/Industrial sector. With a starting point to develop IMG AB?s logistic and distribution the company has decided to survey the present logistic at their subsidiaries, mainly concentrated on the goods for delivery.

Fieldstudys on 22 farms (23 silos) to study relationships between the actual particle size of the maize silage and the theoretical length of cut. The measure of theoretical length of cut were stated by the farmers and not measured by us. Particle size of maize silage was determined using the New Penn State Forage Particle Separator. SLU Skara made a special sieve for us, that had larger holes than de original sieves. The samples were shaken after instructions and then the material was weighted. We have also been taking out samples for microbiological analyses from the silos on 13 of the farms.

To build high-rise buildings made of timber has for long been limited by national laws, due to the lack of knowledge in engineering solutions. Frame structures made of wood has for a long time been associated with major fire hazards and consequently lower safety and this connection is still being made today. The increased environmental awareness in recent years has contributed to the exploitation of indigenous building materials, including wood from our own Swedish forests and has become increasingly common. Increased knowledge about how structures behave in fire and how they can be protected in order to achieve safe timber structures has resulted in a growing interest in these structures in the construction industry. Research in the area is constantly updated and new laws allow any number of storeys in wooden buildings in Sweden as long as the performance requirements are fulfilled.The main part of this work has involved calculations of the fire resistance and load bearing capacity of floor and wall constructions.

By limiting our horse?s freedom of movement, we restrict their opportunity to forage, which is one of their most important needs. If their need of forage is not fulfilled it can lead to frustration, which might manifest itself in abnormal behaviour, like the oral stereotypies for example crib-biting. It is a held belief that the horse swallows air while crib-biting, which they don?t, and that swallowed air causes colic, and the belief that other horses can copy the behaviour, leads to the use of many methods to prevent the behaviour.

This is a final year project considering constructional techniques for joining cavity walls. The project is related to an ongoing scientific programme about the restoration of The City wall of Visby located on Gotland. The programme was set by Riksantikvarieämbetet as a reaction to a collapse of the outer masonry wall shell which took place in February 2012.The City wall of Visby is a medieval fortification built out of limestone during the 13th century. The wall is constructed as a cavity wall with two separate masonry shells connected to each other through an intermediate core. During the 14th century the wall was heightened which lead to a higher stress, especially in the outer wall face.

The Swedish Transport Administration manage nearly 4,000 railway bridges in different condition and age around the country. These bridges is in constant need of maintenance and requires continuous inspections. This thesis is designed as a damage investigation on a single-track railway bridge south of Solvarbo in Säter municipality. The railway bridge is in operation and serves over 10,000 trains a year, everything from speed trains to freight trains. The bridge is built as a beam bridge, simply supported over a road.

Högre byggnader i Sverige stabiliseras vanligen med väggar som dimensioneras för att uppta både skjuv- och tryckkraft, så kallade ?Shear-Walls? eller stabiliserande väggar. Vid dimensionering av dessa element refererar den aktuella normen, SS-EN 1992-1-1 (EK2) till fackverksmetoden. Då det råder brist på praktiskt applicerbara dimensioneringsregler för fackverksmetoden för stabiliserande väggar används i dagens läge ofta den amerikanska betongnormen, ACI som med sitt enklare och mer praktiska tillvägagångssätt konkurrerar ut fackverksmetoden. Eftersom dessa hus byggs i Sverige ska Eurokoderna tillämpas, därför är det intressant att veta hur stor skillnaden i både armering, men även styvhet blir om båda metoderna tillämpas på ett väggelement.

This degree project concludes the Innovation and Design Engineering programme at Karlstad University. The project was carried out by David Brocker, Erik Hallberg and Andreas Hertzman during the spring of 2006 and corresponded to 15 weeks of work per student. Assigner was Martin Larsson at Arexor and instructor at Karlstad University was Monica Jakobsson.Arexor has a patent to a construction of an electrical skirting board with moveable wall sockets, called Electrical Track System. The lowest parts of the interior walls along the floor are today almost always covered by a conventional skirting board. Arexors patented product replaces that with the possibility to move and increase the number of wall sockets by choice along an electrical skirting board.
