EN TOTALKOSTNADSJÄMFÖRELSE MELLAN CELL-, SKUM- OCH LECA-BETONG
This report provides a comparison between the products cellular concrete, foam concrete and LECA concrete. The questions to be answered during the work is how the cellular concrete stands up in cost terms to the existing competitors on the market, how the concrete products differ in design work, and in which situations the concrete varieties are preferred to use.Cellular concrete is a variant of ordinary concrete, with the difference that the ballast is exchanged from stone materials to expanded polystyrene beads (EPS). This substitution gives a product with higher insulation values but lower weight than ordinary concrete.The work was carried out by designing a survey which was sent to two hundred randomly chosen companies across Sweden, to see the building industry?s opinion of the product cellular concrete. The survey showed that cellular concrete was equals its competitors in terms of price, while the product was said to be more flexible, quicker and easier to cast.Then some of the companies, who participated in the survey, were interviewed to see more carefully, how the price, the workmanship and the time for casting and dehydration differed between the products.
Pallhantering på Findus - Flöden , problematik och alternativ
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.
Skredriskutsatta områden vid ett förändrat klimat - Konsekvenser för vattendistributionen i Göteborg
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.
Majsensilage - partikelstorleksfördelning och hygienisk kvalité :
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.
Tillämpning av nya beräkningsmetoder för branddimensionering av träkonstruktioner - analyser och jämförelser
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.

Krubbitning hos häst på olika strömaterial :
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.
Akustisk trädgårdskonst : att ge sonisk karaktär åt en plats
Ljud och trädgård är kanske inte det första par man tänker sig som gifta men de tus
historia kan spåras längre tillbaka i tiden än man kan föreställa sig. När jag bestämde
mig för att skriva min kandidatuppsats om akustisk trädgårdskonst trodde jag att
ljudinstallationer i trädgårdar och parker var ett nytt fenomen. En helt ny värld
öppnade sig framför mina ögon då jag insåg att så inte var fallet. Konstgjorda
ljudkällor, såsom gyllene fåglar och vattenorglar, har kommit och gått genom tiderna
medan naturliga ljud, såsom vind och fågelsång, bestått. När det kommer till vår
egen tid är trädgårdsljud, även om moderna material och tankesätt används, en
konstform som starkt präglas och inspireras av sin historia.
Du kan skapa olika sorters ljudmiljöer i din trädgård beroende på vad du väljer att
använda för material.
Byggnation av ett tak i Lwengo Basilla : En fältstudie med fokus på infästningar, pelare och bärläkt på en skola i Demokratiska Republiken Kongo
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.

Jämförelse och utvärdering av dimensioneringsmetoder för stabiliserande väggar av armerad betong i höga hus
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.
Electrical track system : Utveckling av ett nytt system, innefattande elektrisk golvlist och uttag, som medger flytt av de traditionellt fasta vägguttagen
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.
"Yes! Man kan bli kranförare." : - En studie av manligt tolkningsföreträde i svensk inrikesnyhetsjournalistik
The free press is an invaluable part of the democratic society and a pillar stone in the creation of ideas, opinions and norms. According to theories such as agenda-setting and framing the media have a significant influence on people?s perspectives and opinions. With this view of media along with the gender system provided by Yvonne Hirdman as a framework, this study intends to examine the gender representation in Swedish domestic news journalism. The study consists of a quantitative analysis of two major Swedish morning papers, Dagens Nyheter and Svenska Dagbladet, where the gender representation regarding journalists, main news sources and pictures are being accounted for.
Kan man ingjuta mer liv i Norra Fäladens centrum? : analys, diskussion och förslag på hur man kan skapa ett bättre lokalt centrum genom fysiska åtgärder.
This is a master thesis on how to develop the central area of Norra Fäladen, a suburban housing area in the town of Lund, Sweden. The area is discussed on the basis of literature studies, analysis, and place descriptions, which leads on to a proposal. The starting point for the proposal is to create a more lively local centre and to make the area pleasanter for the visitor. A large part of the thesis is devoted to giving a background about local centres and to describe and analyse the area.
Fäladstorget has an important role as a central place for supply and services and as a local meeting place for the inhabitants of Norra Fäladen.
Stadsrum och stadsliv - Bebyggelsestrukturers inverkan på kvalitet och innehåll i det offentliga
ABSTRACTToday's modern technological society is constantly evolving and house planning is one area that is constantly creating new technical solutions. By looking back at selected architectural eras during the 1900?s, the idea is to study and analyse three building structures in Gothenburg with a focus on quality and content in the urban space.In order to provide a background for the three selected areas, their history has been studied. The main question for the research is: how do different building structures affect the content and qualities in the urban space?The areas have been selected to represent three typical epochs in Swedish building history.
