Heavy duty vehicles often have problems with traction during the winter periods. For vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the vehicle to regulate the normal force by lowering the pressure in the air suspension associated with the tag axles or by the lifting of these axles. The vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty vehicles when driving on slippery slopes and how traction can be improved.

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..

Urbanization has for a long time been a threat to our biodiversity. Epiphytic organisms such as lichens have been negative affected by traffic pollution and the new urban environment surrounding their old habitat (van Her 2001). Another epiphytic organism is the green algae Desmococcus olivaceus. Unlike lichens the green algae is favoured by polluted areas. The aim of this study was to investigate if time in urban environments affected the cover of the green algae on old oaks.

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..

A product and design development of a household device which shall dry food waste has beencarried out in collaboration with Smedlund Miljösystem AB.This project has been implemented through several brainstorms and a questionnaire study.A great insight of how it is to work in a project in real work life has this project been givenme. This is a slightly less straight road to a conclusion than in the academic world that I amused to..

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.

This study aims to highlight patients´ experiences about and thoughts of side effects fromelectroconvulsive therapy (ECT), a therapeutic method commonly used when having severedepressions. The framing of questions were how the respondents of this study describe theirlife before, during and after ECT-treatment, how the treatment has affected their daily life andhow these experiences may contribute to the awareness of power in professional relations.The study is based on three semi-structured narrative interviews and the main result showedthat, according to my interpretation, ECT as a treatment obliterated memories, quality of lifeand daily structure for all participants. Unfortunately they have all become subjects ofpsychiatric power and have faced considerable difficulty in getting professional recognitionaccording to their severe memory issues. The respondents have lost the ability to relate totheir past which clearly makes them struggle in their present context. A point in commonamong them is that neither of them wanted ECT but, because of the lack of communicationbetween them as patients and the health care in general, they all ended up getting it..

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.

In the construction industry the number of female managers is very low, only four percent (SCB, 2010). In fact, women with management positions has risen by six percentage overall, the last seven years (SCB, 2010). If women in managerial positions continue to grow at this rate, the proportion of women managers will be equal to that of male managers in 2033. More women are needed in the maledominated construction industry in particular because it is deemed that they have a different way of thinking and acting (Granér, 1994). Nelton (1991) believes that companies can take advantage of female managers to be more competitive on the market, the reason why is because women can see other possibilities when solving problems. Rapacioli (2010) argues that the recruitment of women into management positions not only benefits the individual itself but also the company. We have used a qualitative study with a deductive approach. Six respondents from the same company were interviewed, two of them have management positions and the other four were underemployed.The research question of this paper is: What differences and similarities are seen between male and female leadership in terms of their characteristics in the construction industry?The purpose of this paper is to examine similarities and differences in leadership in the construction industry where the focus is on the female and male characteristics. To fulfill our purpose we chose a qualitative study. We have interviewed six respondents at one company in the construction industry. Two of the six respondents have management positions and the remaining four are employed. In this paper we have concluded that there are some differences and similarities between men and women´s leadership in terms of their characteristics.

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.

To save energy it?s popular to build houses with low energy loss. In these houses the walls are keeping a lower temperature in the external side which leads to a higher relative humidity. In addition more material, such as wood studs, are used which means that there is more moisture to dry. More moisture in combination with higher relative humidity may pose a higher risk of microbial growth.

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.

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.
