Syftet med det här examensarbetet var att undersöka 3-5 åringars förmåga att utveckla sin förståelse för vattnets väg till kranen genom med en pedagogisk aktivitet. Genom den pedagogiska aktiviteten gavs barnen möjlighet att färdas genom vattensystemet med sina kroppar och sinnen, från sjön till kranen. För att kartlägga hur barnens förståelse utvecklats genomfördes kvalitativa intervjuer före och efter den pedagogiska aktiviteten.Jämförelsen mellan resultaten av förintervjuerna och uppföljningsintervjuerna pekar på en tydlig utveckling av barnens förståelse av vattnets väg till kranen, som ett tekniskt system. Flera av barnen utvecklade sin förståelse för att vårt hushållsvatten måste genomgå en reningsprocess, färdas genom olika komponenter i vattensystemet och rör innan det slutligen når kranen och kan förtäras..

When the emissions from the diesel trucks today accounts for a large part of the total emissions from the road traffic, the trend with a more extensive use of diesel trucks for transportation will therefore lead to increasing carbondioxide emissions to the atmosphere. Because of the fact that technical progress in the form of optimized engines and shifts in the means of transport sometimes result in even greater emission levels, other solutions to this problem must be studied to decrease the emissions of carbondioxide from the diesel trucks. The purpose of the thesis is to show how a decrease of the carbondioxide emissions from diesel trucks in Sweden can be achieved in a costeffective way by the use of a carbondioxide tax and a differentiated vehicle tax. The method used in order to fullfill the purpose of the thesis is studies of literature, mainly of public government reports. Literature of enviromental economics will be used to show the need of a tax and how to determine the dynamic effective carbondioxide tax in steady-state.

A new site- and construction-law came into effect in May 2011. The new law, PBL2010:900 implies several different changes of the law. These changes concern bothconstructors, people working in municipality and county councils and other peoplethat in some way are related to the building sector. Except from the change in orderof the chapters and the renewed and modernized language, the law has now beenextended with a few new phases.According to the new law a certificate has to be issued to start and finish theconstruction; the construction consulting has changed name into technical consultingand the protocol for the controls has to show what the control is being compared to.This diploma work concerns control visits on construction sites as related to the newlaw. The reason why visits on construction sites are now implemented in the law isbecause the government saw a lack of trustworthiness in the old law.

To introduce a standardized component assortment takes a lot of effort in order to make real cost savings. The rationalization effect itself is important, but perhaps even more important is to state the aim of the standardization efforts in a well-defined way. How can an organization assure that they are working in a proper way? How do they know that their efforts are being interpreted into the whole organization? And, how do they know that the standardization efforts actually save money? Different components differ heavily e.g. in technical complexity and quality issues.

All around the world more and more people move from rural areas to live in the cities. Because of this, the urban areas have become an important part in the debate about the effects on the environment and sustainability. In many countries word wide initiatives have been taken to build sustainable cities and eco cities, the Stockholm Royal Seaport is one example. The vision for the district is to become a world class sustainable city based on the three dimensions of sustainable development: social, economic and ecologic. The municipality of Stockholm has set requirements for the buildings? energy usage, emissions and amount of waste generated during the building process.

Volvo Cars in Skövde manufacture and assemble Volvo engines. When attaching the ignition coil to all 4-cylinder engines, a special mounting tool is required. This mounting tool is currently manufactured from injection-molded polyoxymethylene (POM), a thermoplastic. It has been noted that the life span of the tool is shortened as a result of abrasive wear that occurs during the attachment process of the ignition coil.An investigation of the possibility of manufacturing the mounting tool with a 3D-printer is undertaken in cooperation with ÅF, a consultant to Volvo Cars. A literature study is first presented to introduce broader knowledge on the subject.

The Swedish automotive industry has since way back been struggling with bankruptcy, abroad buy outs and staff cuts. Competition and pressure on prices are two factors that affect the automotive industry. Because of this, the companies are pressured to continuously developing their work in addition to be able to compete on the market. The aircraft industry has successfully managed to implement additive manufacturing (AM) and for motorsport has several components manufactured with AM been used. When AM is used as a manufacturing method, there are a number of advantagesthat follows.

In order to get a better understanding of the interaction between employees and their technical work tools one needs to know what factors influence the interaction. The purpose of this study was to examine if there is a correlation between the personality traits Extraversion (E) and Neuroticism (N), tested with Eysenck Personality Inventory (EPI), and experience of the new Intranet among employees at The Swedish National Transport Administration (SNTA), and also to gather information of employees? opinions about the new Intranet. A survey, containing questions about the Intranet and a personality test (EPI), was posted on SNTA?s Intranet for eight workdays (N = 88, females = 53, males = 35).

Poorly maintained forges are a common sight in the province of Gästrikland. Because of their changed appearance, possible move from the origin location and poor items related knowledge they will rarely qualify for the range of funds available through Länsstyrelsen. Therefore this study deals with the problems associated with the forges in southern Gästrikland, i.e. Hedesunda and Österfärnebo parishes.The aim of the study is to increase the items related knowledge of forges and perhaps form the basis for restoration projects in the area. Eleven forges have been examined and the changes they have undergone have been highlighted.A forge was erected on the farm and was used for the households needs such as producing and repairing tools.

The aim of the present study is to describe the experiences of high school students as regards the effects of their activities, in and out of lessons, being published on the web. In addition, a further purpose is to acquire knowledge about whether a website could be used as means of increasing the students level of attention, and focus, to their activities in school; and, furthermore, how such a website should be designed to correspond with the students requests.The implemented methods are interviews with students, school administrators and teachers. A survey was conducted covering the student?s personal experiences and opinions. Furthermore, an interface test of the website was performed.

Although being recognized as holding great cultural-historical significance by local officials, numerous parts of the functionalistic development along Friggagatan became demolished in 2008.This bachelor thesis have surveyed how the planning process proceeded through various municipal committees, and moreover, how different interest groups gathered around certain discursive attitudes. As a consequence of various paradigm shifts in society, e.g. that local government gradually are depending on private economic initiatives, there are to some extent a fear among politicians that cultural-historical demands can risk economic growth.Nevertheless, a building or a development are in fact bearing different value-perspectives, such as economic, functional and cultural-historical. Due to the fact that the heritage-sector has limited resources, in combination with sometimes vaguely and obsolete conservation documents, the sector have difficulties of responding common economic arguments, which leads that the real estate-owner gets total interpretative prerogative.However, despite a sometimes suspicious political attitude towards an improved conservation document, e.g. with continuously updates concerning a building?s technical and economic status, there are some political initiatives working towards it..

AbstractThe urgency to find alternative fabrics to conventionally produced cotton is increasing as vast amounts of agrochemicals are used and a lot of irrigation is required. In this literature survey the potential of organic cultivation practices to produce highly qualitative hemp fibre, suitable for the textile industry, was investigated. The definition of a fibre in the textile context as well as of the qualities that are essential for a textile fibre was necessary as a base for the discussion in this thesis. The quality parameters looked at were fineness, strength, length, friction, and colour. The impact of external growth factors and plant development on these quality properties are discussed.

Steam was used as a site preparation method to eliminate unwanted bilberry (Vaccinium myrtillus L.) in the boreal forest. The efficiency of steam to suppress bilberry was compared with prescribed burning and cutting the bilberry. Different combinations of steaming and/or cutting the bilberry were set up to investigate in which way steaming and cutting influenced the sprouting and regrowth of bilberry. The regrowth of the bilberry vegetation was monitored for 40 month. Steam was most efficient in suppressing bilberry.

The purpose of this thesis is to investigate reading habits among parents of preschool children who do not use the public library. Another aim has been to investigate why these parents don?t use the library and if there is anything the library can do to change this. Little research had earlier been done on this subject. The theoretical framework consists of two different models.

The aim of this two year master thesis is to study the knowledge production within the field of Textile Studies at Uppsala University, with special focus on the use of artifact documentation as a research method. With domain analysis as a theoretical framework, ontological and epistemological assumptions as well as historical and social aspects are studied in relation to the research process. Qualitative research methods are used, including interviews, observations and text analysis. In the analysis of the knowledge processes in the field, perspectives on tacit knowledge and the concept of documents, are used as a theoretical basis. In the field of Textile Studies, the artifacts are used as one of the main objects of study, along with archival and pictorial sources. The main epistemological assumptions are that artifact analysis is dependent on a knowledge base, where technical handicraft skills, contextual knowledge and practical experience of object observation are the most important qualifications.
