Askans inverkan på beläggningstendensen i ett biobränsleeldat kraftvärmeverk och växtplatsens påverkan på askegenskaperna :

This report was written by Sofia Ericson and describes the degree thesis with the title: ?Connections between the growing site of bio fuel, the chemical composition of bio fuel ash and the deposit growth in a bio fuel fired boiler.? The purpose of this degree thesis was to avoid melted deposit growth in the bio fuel fired boiler at ENA Kraft in Enköping. Potassium and sodium are known to lower the melting point of bio fuel ashes and are therefore not wanted in the trees in higher amounts than necessary for the growth. Silicon is also known to be important for the deposit growth but it is not possible to say in general if higher or lower contents of silicon is better. The relation between silicon and other chemical substances is more important than the total amount of silicon.

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.

Beräkning av bindningsenergier i atomära system med Bi2Te3 och SiO2 ? Simuleringar med täthetsfunktionalteori

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.

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.

"Inte bara glass och ballong" En kvalitativ studie av svenska militära utlandsveteraners upplevelser av stöd och förståelse från Försvarsmakten och allmänheten efter utlandstjänstgöring

Kvinnligt karriäravancemang i allmänhet, och kvinnors problem att nå organisatoriska toppositioner i synnerhet, är ett ämne som länge varit föremål för diskussion. Åsikterna om hur snedfördelningen ska åtgärdas går isär och har lett till heta debatter. Inte minst förslaget om lagstadgad kvotering i svenska styrelser har rört upp känslor och debatterats intensivt. Stiftelsen AllBright la 2013 fram en rapport som visade på att det finns fler med namnet Johan i svenska styrelser än det finns kvinnor. Detta uppmärksammades stort i flertalet media.

Från ståtlig befästning till vittrande världsarv : En jämförelse av byggnadstekniska metoder för sammanbindning av skalmurar

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.

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.

Yeast in forage crops and silage aerobic stability at 15 Swedish dairy farms

This study investigates the role of yeast in green crop and its impact on the aerobic stability of silage. Fresh crop was collected from 15 farms in southern and middle parts of Sweden during the summer 2014; samples from the primary harvest was collected from eight farms and samples from the first regrowth harvest was collected from seven farms. The grass was ensiled in 1.7 l glass silos. After three months of ensiling, silos were opened and silages were stored aerobically for 10 days. Samples from both harvests were ensiled in completely airtight silos, but samples from the second harvest were also ensiled in slightly ventilated silos. Chemical analyses and yeast counts were performed for fresh crop and silage.

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.

Hackerör på Sydsvenska höglandet : vad skiljer röjningsröseområden från celtic fields, stensträngsområden och bandparcellområden?

From the pre-Roman and Roman Iron Age, a number of different fossil agrarian landscapes can be found in southern Sweden - clearance cairn areas, celtic fields, stone-wall complexes and geometrically laid-out strip fields. With two different comparative analyses, this paper tries to explain some of the differences between clearance cairn systems and the other fossil field systemsThe shape of the early Iron Age agrarian landscape varies between different provinces of southern Sweden. At Gotland, celtic field systems were laid-out before 500 BC. In Småland at the same time, areas with clearance cairns were created. How can the difference be explained? The different physical appearance of clearance cairn areas and celtic fields can be explained by the different ways to handle the ard in till and in sandy soil.

Externa mentorsprogram - För kvinnor som vill avancera i karriären?

SammanfattningProblemdiskussion: Inom området ledarskap så domineras de högre positionerna av männen, och har så alltid gjort. Kvinnorna som vill avancera stöter på fler svårigheter än män, och detta fenomen har sedan 1986 benämnts The Glass Ceiling ? då begreppet först dök upp i Wall Street Journal. Kvinnor verkar alltså slå emot ett glastak på sin väg mot toppen, som hindrar dem från avancemang. För att överbygga hindren har en del olika lösningar föreslagits i befintlig forskning, och vi har valt att fördjupa oss i ämnet externt mentorskap.

Vegetationsbekämpning i dräneringsdiken inom ett järnvägsområde i Västra Götalandsregionen

My purpose with this thesis has been tostudy the intersection between Landscapearchitecture and Land Art. They both relateto the landscape in some way whetherit is to the urban landscape or thenatural landscape.What tangent points are there betweenthese two subjects, and can you learnsomething of the artists approach to thelandscape?Land Art is an art movement that began inthe late 60?s, what links are there to thecurrent landscape?Last summer, I travelled around the U.S.for a month and visited the three classicLand Art projects. Lightning Field in NewMexico, by Walter De Maria, Sun Tunnels inUtah, by Nancy Holt and the Spiral Jetty,also in Utah, by Robert Smithson.The sites where visited from half a day upto 24 hours and was described and analyzedwith text and photographs.To visit these sites has been crucial formy thesis and will affect my future workas a landscape architect. The use of themethod has been a thought of mine for along time, particularly to analyze ordescribe a landscape with images.

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.
