Kärnkraftens värde i framtiden : en jämförelse med kraftvärmeteknologi från biobränsle
The debate on the future of Nuclear power in Sweden has increased with the discussion on global warming. The uncertainty of fossil fuel- and carbonprices the latest years has aroused considerable interest in Nuclear from power companies, industry and politicians. Nuclear power plants have negligible CO2 emissions and are not directly affected by increased price of emission rights and fossil fuels. The future power production needs to reduce its emissions of greenhouse gases to become sustainable.
The purpose of this study is to examine the value for power producers to have the option to invest in Nuclear power and how a Nuclear power venture would affect future electricity prices. The study uses two methods, a traditional cash flow model and real option analysis, to estimate the value of Nuclear power.

Stadsklimat/Gatuklimat :
The purpose of this paper is to understand the climate of the street and how it can be modified to better meet the needs of the street and the user groups. At the same time the conditions of the street and its surroundings also has to be taken into account. To accomplish this it is necessary to have a broad knowledge of the climate conditions in the city. Therefore an overview of the climate elements and how these are modified in the built-up areas are given. The part of the paper which deals with the city climate has a global approach to be able to give an as complete picture as possible.
Fysikalisk modellering av klimat i entreprenadmaskin
This masters thesis concerns a modeling project performed at Volvo Technology in Gothenburg, Sweden. The main purpose of the project has been to develop a physical model of the climate in construction vehicles that later on can be used in the development of an electronic climate controller. The focus of the work has been on one type of wheel loader and one type of excavator. The temperature inside the compartment has been set equal to the notion climate. With physical theories about air flow and heat transfer in respect, relations between the components in the climate unit and the compartment has been calculated.
ScenÖsterlen. Kulturprojekt för barn och ungdomar - betydelsefullt i en mindre kommun?
AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and District heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power. ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant. As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol. Etanolens framtid vilar på bra lösningar för framställning. I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle. Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.
Utvärdering av miljönytta för olika miljöcertifieringssystem för byggnader : En jämförande fallstudie på Swecos kontor i Stockholm, Göteborg och Malmö
This thesis examines the environmental benefits resulting from the choice of environmental certification scheme, with focus on energy. This was carried out by studying the measures that were implemented as a result of the certification of Sweco's three largest office buildings in Stockholm, Gothenburg and Malmö. The office property in Stockholm has been certified with the Swedish Environmental Building, Gothenburg with the British BREEAM and Malmö with the U.S system LEED.The results from the study indicate that an environmental certification can reduce the energy consumption by up to 59 percent and the water consumption by 20 to 66 percent. However; the interviews, literature study and simulations in MATLAB indicate that the size and scope of these environmental benefits depend on several identified factors: the type of building and its conditions, system selection, grade level, the choice of indicators, the ambition of those involved and when in time the certification process begins. The comparison between Environmental Building, LEED and BREEAM showed that Environmental Building for the office property in Stockholm gave the largest environmental benefit in terms of reduced energy consumption thanks to several large measures.

It is also to describe the access of material available in prevention of cross infections. The study was also carried out with a comparative and quantitative run up design. The study is based on a questionnaire in the district of Gävleborg in the spring of 2009. Nurses, auxiliaries and carers whom were in close contact with patients were asked to join the study.
Hur arbetar distriktssköterskan inom primärvården med sjukdomsförebyggande metoder?
Bakgrund: Den medicinska och ekonomiska kostnaden för hjärt- kärlsjukdomar är idagmycket omfattande. Största delen av dessa sjukdomar liksom andra kroniska, ickesmittsamma sjukdomar som cancer, lungsjukdom och diabetes, hör ihop med påverkbara,livsstilsrelaterade riskfaktorer. Genom att göra hälsosamma val när det gäller mat, rökning,alkohol och motion kan livsstilssjukdomar förhindras eller fördröjas. Livsstilsfrågor är enav distriktssköterskans huvuduppgifter och efter vårdvalet är det få distriktssköterskor somverkligen får arbeta med detta. Syfte: Syftet med denna studie är att beskriva hurdistriktssköterskan arbetar med sjukdomsförebyggande metoder inom primärvården.Metod: Studien är baserad på en kvalitativ metod med en induktiv ansats.
100 % svenskt foder till mjölkkor :
As for today, a large quantity of protein feeds is imported from other countries to be used in
the Swedish dairy production. The main import is soya from Brazil. The soya-production in
Brazil results in negative consequences for the natural environment in the area, and the long
transport of the feeds requires a lot of energy. The organic dairy production in Sweden is,
with the highest probability going to be forced to use 100 % organic feed to the cows in the
year 2005, due to new EU-rules. These are some of the causes why there are reasons to look
closer at the possibilities to feed Swedish cows with only Swedish feeds.
In this study, I have looked at the KRAV-rules for organic feeding, where the goal is feeding
with only KRAV-approved feeds.
Synen på idealelever i Pedagogisk tidskrift 1945-1962 utifrån en differentierande och exkluderande pedagogisk diskurs
AbstractSeveral of researchers have reflected that the school ought to be developed to a learning organization. A method as proceed from such a perspective and should be able to match a local child- and educations administration is problembased school development. To investigate in which ways a child- and educations administration prosecute a problem based learning inside the organization a case study was used as research strategy. The question this report gives answer to is:In what/which way works a child- and educations administration in a rural district with a method to fulfil a problembased learning.To collect empiric data a canvassing inquiry was accomplished among the child- and educations administrations group of management. According to the research result it can declares that there are good conditions for the organization to prosecute problem based school development, but there is yet a great deal to do before it´s can be said totally fulfilled.
Vi har i alla fall aldrig varit apor! : En postkolonial studie om kreationism bland unga
This case study examines how a group of upper secondary school students in a multiethnical suburb of Stockholm reason about the theory of evolution. The theoretical background of the thesis is postcolonial and the questions raised were how spread the creationist thoughts are in the group; in what way the backgrounds of the students are relevant to their thoughts; how the students construct the notion of the theory of evolution; how they position themselves and others in relation to the discourse of the theory of evolution; if there are any differences between students at the collage program of natural science and the collage program of social science, and in that case, what differences; and who or what inspires the young in their thoughts about the theory of evolution. To answer these questions both a survey poll and interviews were used. The result of the case study showed that a majority of the students at the investigated school has creationist ideas and that the students profiled on social science have creationist ideas in a wider extent. Another result is that the religious background seems to be relevant to develop creationist thoughts, while the variables gender, home district and educational level did not differ the creationist group from the whole group.
Distriktssköterskors reflektioner kring att arbeta med kroniska bensår : en intervjustudie
SammanfattningSyftet med studien var att beskriva distriktssköterskors reflektioner kring att arbeta med kroniska bensår. Studien genomfördes som en semistrukturerad intervjustudie och hade deskriptiv design. Totalt sexton distriktssköterskor intervjuades, åtta distriktssköterskor med landstinget som arbetsgivare och åtta distriktssköterskor med kommunal arbetsgivare. Materialet analyserades med kvalitativ innehållsanalys. Resultatet visade att distriktssköterskorna ansåg att arbetet med kroniska bensår var ett vanligt förekommande arbetsmoment samt att bristande samarbete från patienten var en bidragande orsak till långa behandlingstider och utebliven sårläkning.
Delaktighet hos barn i behov av särskilt stöd : En studie om hur möjligheten ser ut för barn i behov av särskilt stöd att få vara med och påverka vardagen i förskolans verksamhet
Earlier studies shows that democracy within the preschool is an important and on-going work, but could implicate certain consequences. For example that goals regarding democracy and influence in the preschool, rarely is done in practice but instead remains just words on a paper. It could also mean that the pedagogues lack education and knowledge within the area, but also how they react to the influence of children. Preschool is expected to be a place for all children, no matter what luggage the child is carrying. The luggage is filled with the life experience, the personality and in this case the needs that the child has. The needs could be anything from nearness to physical and psychological disorders that requires more pedagogical attention.
Hur påverkar förtätningen stadens grönstruktur? :
Urban density is not new, but rather one side of the continous processes of change underway in the city. During the urbanizing boom of the industrialization, when the cities grew bigger, the first spaces to be built on were vacant and planted areas in the interior of the district. The gardens that once were there were replaced by yardhouses. The idea of urban density is that a dense city means less distance between residential areas and workplaces, resulting in fewer shipments and travelers, which ultimately leads to lower energy consumption and lower emissions. Urban density may lead to shorter
distances, but not necessarily.
In the wake of urban density the greenstructures of the city is shattered.
The possibilities for green areas to contribute to the health of the city and its inhabitants is dramatically reduced.
Konstruktion av kostnadseffektiv fläkt till härdningsugnar
Scana-Booforge is a Swedish company which specialize in heat treatment of various metal. The treatments take place in quenching ovens, where fans are used to circulate the hot air. The fans used today do not have a satisfactory lifespan. This thesis aims to develop a new design of the fans for the quenching ovens, and the goal is that the new fans will bring cost savings for Scana-Booforge.The design development process started with mapping out the environment in which the fans operate, and with analysis of the existing fan structure and damages, in order to establish the cause of failure and of short durability. The performance of the fan were also established at this stage.
