The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

 This report will describe a project between two students from Karlstad University and Markus Norström from Hovercraft solutions. The project aim was to develop a cabin for the hovercraft 380TD. The project was divided into two sub parts; one concerning the design of the cabin and one concerning the engineering. Throughout this rapport you can follow the engineering part of the project. The project has followed a systematic product development process resulting in optimized results for material selection and engineering solutions.

Expansion och förtätning av städer leder till att såväl areal som andel hårdgjord yta ökar i våra stadsmiljöer. Detta genererar en ökad dagvattenavrinning eftersom regnvattnet inte har samma möjlighet att infiltrera i naturmarker och grönområden. Den ökade mängden dagvatten riskerar att orsaka problem i områden där ledningsnätet dimensionerats för de dagvattenmängder som tidigare varit aktuella. Att utöka ledningsnätets kapacitet är ofta mycket kostsamt och det är därför önskvärt att istället minska belastningen på de befintliga systemen. En allt vanligare metod för detta är att byggnaders takyta bekläds med växter, så kallade gröna tak.

The aim of this study is to investigate wether the participatory democracy is a threat or a complement to the representative democracy. To achieve my purpose I will focus on two different lokal councils, the civil council in Hovsjö and the youth council in Västra Skogås, which have been objects of the urban policy in 1998. The theoretical framework on which this study is based consists of the participation democratic theory, representative democratic theory and implementation theory. By problemizing these theoretical frameworks in comparison with eachother I will mapp how these two lokal councils were implemented. The research question is: In what way was the civil council and the youth council a complement or threat to the representative democracy? In which way was it difficult to implement them?The method used for this purpose is a qualitative comparative case study.

What is an economic crime? Who is an economic criminal? How do we speak of the phenomenon and what does they way we speak mean? The immediate result of the study is that there is a stereotype image of the economic criminal that is produced within peoples speech. This image contains characteristics that bring the subject, the economic criminal, far away from the traditional crime subject, and brings it closer to a non-criminal subject. This motion render possible that economic criminals can talk of themselves as ?not bad people?, ?normal? and ?like everyone else?.

This work has been done to develop a plan for a future dairy barn at theGästgivaregården and to show the space needed for cows and replacement heifers. Itwould also show the storage that will be needed. The design was largely based on resultsfrom studies on six different farms, but also the facts that are taken from research papersand articles in order to compare theory with practice. Because some farms only whereinterviewed by phone I have used a query form to obtain comparable resultes.The aim is to build a new barn with Automatic milking. I've drawn a milking stable for120 milking cow and replacement heifers with the capability to house up to 140 milkingcows if the farm would expand in the future.Calculations of feed amounts and space requirements have been made to see how manyhectares are needed to supply the cows and replacement heifers with feed and to knowabout what size of storage space is required.The investigations made in this writing are to answer questions about the AMS-unit`sposition and how to best maintain a good health status in the herd.

AbstractThe struggle for land has been an issue ever since Brazil was colonized by the Portuguese Crown. The deep social inequalities that the country faces were raised then. More than 45% of the agricultural land is controlled by only 1% of the landowners. There have been many movements since then, who has fought for agrarian reforms.MST, the largest social movement in Brazil, was born in the 1980s. They managed to mobilize the peasants and the poor people.

Webexhibits is a growing but unexplored, cultural phenomenon that indicates a new use of the Internet for cultural communication. In the essay two quantitative methods, logganalysis and websurveys, have been used to study the visitors in 5hus.nu. The purpose is to generate knowledge about webexhibits as a cultural manifestation and medium by studying the experience and actions of its visitors. To achieve the aim the paper explores the methodological questions of how to study webusers. Theories about the exhibition as a medium and the web as a virtual area of exhibits have been used to understand and interpret the results.

The Essay starts with studying the time after the Second World War and its boom, the force behind many of the abandoned locations we see in our city today. Thereafter the idea of place is looked into, its importance for the individual and how the own individual experience affects the experience of place. It is about how we can create own places and through that recapture the city and give it meaning and contents again. The social aspects are being discussed as an important component of creating a feeling of reality. Further studies the abandoned rooms historical values since the past have an ability to raise the experience of a place. How decayed depends highly of economy and how we have gotten so used to changes that we accept capitalism as a driving force to decay is also being discussed. Thereafter the planers roll for the abandoned places in the city is being raised.

Människan är i allt större utsträckning urban och när städerna förtätas är det ofta friytorna som går förlorade. Detta trots att grönska har flertalet positiva effekter som att förse oss människor med livsnödvändiga ekosystemtjänster. För att åstadkomma ett hållbart stadsliv måste stadens friytor planeras på ett medvetet sätt som gör dem attraktiva och hälsosamma för människor, djur och växter. Att integrera ekosystemtjänster i planeringssammanhang är ett angreppssätt som används allt mer för att främja en hållbar stadsutveckling. I Malmö som beräknas växa med 100 000 invånare de närmsta tjugo åren finns en ambitionen om en tät och samtidigt grön stad.

?Urban Leftovers ?Problem eller potential? handlar om stadens överblivna ytor och stadens fragment. Ämnet överblivna ytor i staden är aktuellt och rör sig ofta i gränslandet mellan arkitektur, planering och konst. Man kan förhålla sig till dessa icke-definierade platser på olika sätt men gemensamt är att de i grund och botten berör frågan Vem har rätt till staden? Ofta har de överblivna ytorna inte någon egen funktion utan finns enbart som gränser eller skyddszoner för att skilja andra funktionsområden från varandra.

Över hela världen pågår en kraftig urbanisering och idag lever mer än hälften av alla människor i städer. Många utvecklingsländer hinner inte med att generera hållbara och alternativa försörjningsmetoder till den allt större urbana befolkningen. Allt fler lever i en tillvaro som präglas av fattigdom. Kraftfulla planeringsstrategier krävs för att förbättra dessa människors levnadsförhållanden och därmed också verka för en hållbar utveckling. Uppsatsen presenterar det urbana jordbruket som en i dessa avseenden möjlig strategi. Urbant jordbruk finns i alla städer och har gjort det i alla tider.
