KVARTERSINTEGRERING
Through the different stages of life people have different requirements for their homes. The requirements changes depending on people?s life situation, lifestyleand age. Depending on where people are in life they live in different place, often in areas with other people who are in the same stage of life. In Sweden, this separation has always been noticeable, sometimes more than other.
Jämförande LCA av engångssängkläder och tvättbara sängkläder i sjukvården
Inom sjukvården används ? precis som överallt där människor sover ? sängkläder av hygienskäl. Problem med smittspridningar av typen multiresistenta bakterier (MRSA) och spridning av andra sjukdomar har drivit företag som Cellcomb i Karlstad AB till att utveckla engångssängkläder för att förhindra detta. Engångssängkläderna är skyddade av en biofilm som ska ge ökat skydd mot bakterier och fungerar som en barriär så att inte vätska tränger igenom. Problemet är att det inte finns mycket till underlag för hur engångssängkläderna står sig mot vanliga sängkläder ur miljösynpunkt.

Framtidens elnät : Hur elbilar och solceller påverkar på det lokala elnätet
The purpose of the project is to determine the impact of solar cells and electrical vehicles on the future electricity grid and distribution network. Future electricity grids will be affected differently than it does today. Therefore, it is important to determine the impacts so that the current electricity distribution system can be developed and redesign to achieve the future demand. In Sweden, government has changed rules and laws in order to make it easier for private sector to invest in renewable energy sources. Our project focused on the impact of the solar cells and electric vehicles on the low voltage electricity distribution.
Utbildningsnivå i riksdagen : utbildningsnivå hos riksdagens ledamöter 1971-2006
In the past decades the level of education of the Swedish population has steadily risen. This paper asks questions about the level of education level among members of the Swedish parliament, Riksdagen. The answers are found by studying biographic data over members of parliament between 1971 and 2006. In 1971 a new riksdag, enkammarriksdagen which consists of one ?House?, was founded.
Miljöbyggnad i ombyggnadsprocessen : Miljöcertifiering av Jakobsbergsskolan i Kristinehamn
Climate change is an increasingly widely known concept. In the EU the construction sector is responsible for more than a third of the carbon dioxide emissions and 40 % of the total energy use. In Sweden, measures have been taken to prevent this climate change. By 16 targets, three of which can be linked to the construction sector, Sweden will reduce the negative trend. None of the three goals with relation to the construction sector will however be achieved before 2020.
Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration
As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
Värmeöverföring i bergvärmesystem : En numerisk analys av den ringformade koaxiala borrhålsvärmeväxlaren
The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.
Informationsstyrning av en försörjningskedja i ett icke tillverkande företag.
In this report listed buildings, according to the Swedish Heritage Conservation Act, have been studied with a focus on cases where economical compensation has been given to the owner of the building and cases where the listing of the building has been appealed by the owner. In order for a building to become listed it needs to be particularly valuable from a cultural and historical standpoint. The listed buildings are protected through a list of regulations that determines which parts of the building can or cannot be changed, what methods and materials should be used for changes and repairs, and how the building should be maintained. These regulations should as far as possible be formulated in agreement with the owner, but a building can become listed against the owners will. To decrease the damage this causes the owner he can in some cases have the right to economical compensation. There is also a possibility for the owner to appeal the listing of the building.
Designerrollen i en webbdesignprocess
This study investigates if, and in that case, how design theory is applied in practice in the web development field. Prior research has focused on methods used in the web development field. We wanted to study the designers role in a web design process by comparing existing designer roles with design theory literature. We did qualitative interviews with two practitioners at two different communication agencies in northern Sweden. Based on our qualitative data and literature review we have concluded that a designer has to devote a lot of energy on requirements engineering in order to develop a clear understanding of the design situation..
Landsortsdeckare - den nya hembygdslitteraturen? : Analys av tre deckarserier från Sandhamn, Kiruna och Öland
During the last years the number of Swedish detective stories which take place in the province outside the big cities has increased enormously. In this study I have analysed the novels by the three authors Viveca Sten, Åsa Larsson and Johan Theorin to investigate the connection between the milieu and the story and in what way it is involved in the crime riddle.They all keep to the formula of the classical detective story but represent different variations within this formula. In spite of the differences in their stories the basic pattern is the same. As their protagonists the authors are emotionally connected to the place in the novels. This connection it strengthen by the authors themselves as well as the publishing companies when introducing them on the market.
Effektiv lagerstyrning genom tillförlitlig prognostisering : Effective inventory control through reliable forecasting
This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.
Landskapsplanering ur ett hållbarhetsperspektiv :
Environmental problems are accelerating with energy consumption and the release of greenhouse gases as the major issues. This affects landscape planning mostly through environmentally hazardous transportation and heating of buildings. In environmental work, the term "Sustainable development" is often used. This term was coined in the Bruntland report in 1987. A number of frameworks have been developed to clarify the term and to remind the user about relevant aspects of sustainability.
Estetiska lärprocessers betydelse för barns språkutveckling : En studie om pedagogers tankar kring bildskapande för att främja barns språkutveckling
This master thesis is based on the sociocultural perspective. A qualitative research study was conducted to investigate children's attitudes towards reading, texts and libraries.The theoretical background is constituted by ideas from the new sociology of childhood, literacy-studies and reader-response theory.The study was conducted with 23 children, 13 girls and 10 boys, participating in focus groups.The results of the study reveal that children's literacy-activities in school are strongly influenced and limited by adults. Children's interest in pictures and non-fiction-reading do not correspond to the school institution that favors traditional media and fiction. The study also reveals a gender division between children's literacy-activities that tends to grow with age. All the children in the study regard libraries as book-houses and wished for libraries that combine activity and serenity.The thesis shows the importance of being aware of, and engage in, children's reading-interests and reading-practices if the reading stimulating activities in schools and libraries are to be successful.
Hur bör unga hundar av storvuxna raser utfodras?
The dog is unique in the way that the adult weight can vary 100 folds between the different breeds. Despite this, most of the breeds reach adult size before two years of age. For the large-breed dogs this means a very rapid growth when some of them can have a weight gain of up to 150 times their birth weight. The most rapid growth occurs when the puppies are between three to six months old and that kind of rapid growth during such a short period of time makes these large-breed puppies very sensitive to deficits and excesses of energy, nutrients and minerals. Some examples can be excess of energy, excess or deficit of minerals such as calcium and phosphorus or deficits of protein.
The rapid growth can also make the large-breed puppies predisposed to some diseases affecting the skeletal and joints.
