Produktivitetsstudie Brobyggnad

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

Hur fungerar en glaselektrod?

To understand the glass electrode needs knowledge from more than one level. The construction ofthe glass electrode is one part, an other is the composition and structure of glass. The Nernstequation have an important role, but also the sources of errors in the analysis and the calibration ofthe glass electrode. Focus for this article is how the glass electrode really works and how Gibbs freeenergy made the potential dependent of the concentration of H+and gives the logarithm to thefunction. Nikolskii's ion exchange theory starts to explain the question about how the potentialcreates and Baucke's dissociation mechanism made it more explicit.

PlusTak

Today´s roofing of dwelling houses is a very time consuming procedure, which includes a lot of different steps on the construction site. Not only does it cost a lot of money, but often do problems with rot and mold occur in the attics of houses today. The use of prefabricated modules has seen a great breakthrough in the field of construction of dwelling houses; at least when it comes to foundations and walls, where this type of approach makes the construction process way more efficient. What no one previous has succeeded to develop is a corresponding system for roofs that meets the demands of a dwelling house. Accordingly the goal of PlusTak has been to come up with a proper module system for roofing of dwelling houses, where the roofing is completed to meet the demands of the Scandinavian market. During the project a lot of effort has been put into customer contacts and the usability of the product, as well in the manufacturing process as on the construction site. This development has gone hand in hand with several practical tests and tryouts.

Fuktsäkert byggande : Sjönära bostäder i Östra Hamnen i Västerås

Housing construction very close to the lake Mälaren has become very popular today. One potential problem with these houses is the influence of the sea climate. Unprotected buildings are affected by strong winds and precipitation. So for that reason, it is very important to make an accurate climate investigation and use it for decision-making during the planning of the new settlement.It is very important with a good moisture protection regarding pelting rain, that is the combination of wind and rain. This is more important for buildings close to a lake, as this location normally means a higher exposure to wind.

Att konstruera en gemenskap -teori och konstruktion av virtuella samhällen

Virtual communities are a phenomenon that is becoming more common as the information technology comes with in reach for the general public. This report will bring the theories and construction of a virtual community together. The purpose of this report is to describe the different theories that have emerged from the research within this field and to examine the work procedures that have been used during the development of a site for a MDA-community. The MDA-website is a homepage on the Internet that was developed to bring the students closer together. The report describes the work of the project group, why the website was not completed and at the end the theories are looked at on the basis of the construction of the website..

Hur påverkar byggnadsmaterial av stål en induktiv hörslingas fältstyrka samt frekvensgång?

This research analyzed differences in measurements of magnetic field strength and frequency response in five audio induction loops installed in rooms of wooden construction materials and five audio inductive loops installed in rooms of steel reinforced concrete constructions. The inductive loops were installed at floor level and the measurements were made at the listening height of 1.2m. Measurements of background noise, field strength and frequency response were made at fifteen different measurement points across the room. The research measurements showed that there are differences in field strength and frequency response between these two conditions, whether the audio induction loop is installed in a wooden construction or the audio induction loop is installed in a reinforced concrete construction. The results had a significance level of p=0,05..

Kroppsfett, genus och queer sexualitet : en undersökning av meningsskapande kring kroppar och fett i queera sammanhang

This essay examine the meaning produced around bodies and body fat in the queer community, but also in the surrounding straight community. The author has interviewed fat activists, and are using queertehory, to examine and analyze the relationship between body fat and the understanding and construction of sexuality and gender. The author concludes that even if norms around body shape and body fat are overlapping between the two contexts to some degree, they also differ. In the straight community, people with larger body shapes and sizes are punished, and encouraged to stay, or become, slim. However, in the queer community, ?fat? or bigger body sizes are not frowned upon in the same degree.

Jämförelse av analysmetoder för clickstream-data

Det här arbetet har som syfte att genom en jämförelse av olika analysmetoder för clickstream-data kunna fungera som en vägledning när en metod ska implementeras. Metoden som använts vid jämförelsen är litteraturstudie i och med att de analyseringsmetoder som ska undersökas redan är framtagna och kunskap om dem fås genom att studera litteratur i vilka de förekommer. Ett antal kriterier används sedan vid själva jämförelsen, anledningen till detta är att metoderna ska jämföras utifrån en gemensam grund.De metoder som uppfyllde kraven för de olika kriterierna bäst var page events fact model och subsession fact model. Subsession fact model kan dock upplevas som det bästa valet i alla lägen men samtidigt är den kanske lite överdriven om clickstream-datan bara ska användas till att se hur besökarna använder varje individuell sida för att användas i designsupport syfte. Det går alltså att påvisa att syftet styr vilken metod som är mest lämpad..

Modiga pojkar och hjälpsamma flickor : En diskursanalys hur manligt och kvinnligt framställs i läseböcker från 1950-talet, 1970-talet och 2000-talet

Societies are surrounded by unaware attitudes and views about what is masculine and what is feminine and this can contribute to people being raced differently. Boys and girls are shaped to think and act in different ways from an early age because of their gender. According to the curriculum in the Swedish school system, the school has an important task to prevent such perceptions young people have about sex and gender. Reading books are still a central source where students gather information in the Swedish school. Therefore, I find it interesting to examine how gender is produced in three Swedish reading books from three different periods (1950s, 1970s and 2000s) to see what similarities and differences there are between the texts and the study has been based on three questions:How are men/boys and women/girls described in the reading books based on their characteristics, interests and pursuits?How much space in the texts are represented by men/boys and by women/girls?What masculinities and femininities can be found in the texts and which ones are the most desirable?I have used a text analysis in my research to analyse the three reading books and based my theory on that gender is a social construction.

Logistik i byggbranschen : Fo?r fo?rba?ttrad arbetsmiljo? och effektivitet

Logistics and supply chain management in the construction sector is an area with great potential for improvements. Today, a lot of the workers time is spent on non-value adding activities. Research has shown that waste is a large proportion of the total production cost in building projects today.The purpose of this report is to analyze problems concerning logistics in the construction sector. Two of Skanska?s construction projects in Uppsala have been analyzed to identify problems.

Mediakonstruktionen av den brottsliga invandrarkillen

This qualitative research is about how Swedish media constructs immigrants in articles. The focus of the study will lie on ten Swedish articles and how they stereotype immigrants, but the demarcation will be for young immigrant boys related to crimes. The purpose of this paper is to highlight how media achieves its goal to construct a group as inferior. This will be implemented with the help of articles from different newspapers that reported on immigrants who have committed crimes. We have chosen to look at different newspapers to see if there is a curtain pattern in the construction of immigrant boy.

Vattenanläggningar som gestaltningselement i offentliga miljöer :

Water constructions - as a design element in public spaces is the title of this Master thesis, with a focus on waters function and meaning in the urban environment. By way of introduction, mans relationship to places is described and the factors that contribute to the reality that we prefer some places more than others. A good place to stay is open but well defined, gives protection, offers a good view and is varying in topography and vegetation, together with contents of single landscape elements like visible water. This study then continues to discuss mans relationship to water and its means for our wellbeing. Despite the fact that people have a different relations to water due to personality, background and age, it?s an element that raises positive feelings, interest and aesthetic pleasure for most people.

ENERGIANVÄNDING PÅ BYGGARBETSPLATSER : Analys av införandet av energieffektiva bygg­etableringar

This report is the final step in the Bachelor of Science program in Building Construction Engineering, Department of Engineering Sciences, Uppsala University.The purpose of this study is to highlight the difficulties and possibilities that could involve the introduction of new energy efficient technologies and changing work around this technology. This study focuses on energy use at a construction site or other temporary workplace where so-called portacabins are in place to address the need for temporary facilities.The method for obtaining knowledge on the subject was mainly interviews with site managers working in Svevia AB's various activities. In conjunction with the interviews I visited construction sites and portacabins if it was possible.My most important suggestion to Svevia AB concerns a better organization in order to make poratacabins more efficient on energy and costs. The company should also evaluate and monitor the energy efficient portacabins that are in operation.Expected energy savings of new technology may not materialize if there are gaps in information, education, technical services and technical maintenance. It is very important to utilize the experiences of new technology.

Grundläggning med cellglas : En studie av byggtid och lönsamhet

This report describes a new foundation method and compares it with a traditional founding of concrete. This new method is called the Koljern technique and uses cellular glass which is called Foamglas. The Foamglas is compounded to founding elements by lightweight steel beams. Foamglas is an insulation material with high compressive strength, and is rot, insect, vermin and acid proof. The cellular glass is also fire proof and watertight, which makes it a very good construction material.The report contains a study of a number of cases for which the Koljern technique is compared with a foundation of concrete.
