Uppsalahem is the leading housing corporation in Uppsala with its over 160 real estate properties. Uppsalahem is owned by the municipality of Uppsala, which has a climate and energy goal that aims for 100 MW of solar energy to be installed in Uppsala by 2030. The 100 MW goal, combined with Uppsalahem?s environmental policy, is a strong incentive to investigate the possibility of installing PV modules on the many available roof areas that Uppsalahem possesses. The objective of this thesis is to create a foundation for future decisions regarding PV systems for Uppsalahem.

Previous studies of central tire inflation (CTI) in truck transport of roundwood have shown potential benefits to include more even wood flow and reduced road damage. The greatest benefits are found to be during periods of low bearing capacity such as spring thaw. No previous studies have examined geographical variations in the potential benefit of CTI-equipped trucks. The aim of the study was to develop and use a simple method for geographically prioritizing the use of CTI-equipped trucks within a forest company´s sector of activity.The host company for the study was Holmen Skog. The area studied consisted of Holmen Skog?s entire sector of activity extending from the province of Västerbotten to the province of Småland.

In most countries, the dairy industry focuses on the volume of milk produced instead of its composition. This results in a high content of water and a lower proportion of fat and protein. A high proportion of water is not desirable when processing the milk into various dairy products like cheese, cream and milk powder. High water content also increases the costs for transport and storage, and also an unnecessary, albeit marginal, strains on the world?s water reservoir.

The discussion about high culture and popular culture in our society has been going on for decades. In few places is it as loud as within culture journalism and the critics? society, where the question of what is good taste and what is dumb entertainment constantly gets brought to the surface. Film is a particularly vulnerable area, since it is such a universally appealing and rather young medium. In America and England several studies have been performed of the reviewing society and reveiwers? use of high and low art-discourse in their writing.

The last hundred years humans have drastically changed the amount of available nitrogen in nature. Today human activities release twice as much available nitrogen as all natural processes are doing together. We also have degraded nature´s possibilities to take care of nitrogen through the draining of wetlands and straightening of rivers. In order to regain the potential of nitrogen retention in the water systems there now requires a reshape of the landscape we live in. A planned expansion of the mining activities in Garpenberg, Dalarna, would double the content of nitrogen in the waters below the mine.

Swedish schools have during the last few years started to providing pupils in high school with tablet-computers. By doing interviews I examine how pupils in high school use tablet-computers in different ways and how that affect their studies. From a sociocultural perspective and with the concept of artefacts I analyze how suitable tablet-computers are for studies on this level of education. My results show that the tablet-computers are used as the pupils primary study tool. They are available to all pupils and can be used in most parts of their studies and this creates new opportonities in how to interact with collective knowledge and with other people.

Our purpose with this study was to investigate whether there was any difference between high and low performing students from selected aspects such as choice of studies, achievement, self-image, motivation, confidence and career choices.A training professional in today's schools requires knowledge of how young people think about their lives for us to help students develop both high-and low-performing students. Students have different conditions, but no matter good or bad conditions, each individual pupil must be allowed to develop.The concepts used in the study are of study, self-image, motivation, achievement in the future and career choices. In the background, describes these concepts through literature study. The method we have used was semi-structured interviews. Which means a fixed structure, but with room for follow-up questions.The results of our study indicate that there were clear differences between high-and low-performing students.

The purspose of this study is to investigate how teachers are working to individualize mathemathics education relative to high-performing students and how they define the therm individualization. According to the Swedish curriculum the teaching process should be based on the students prevoius knowledge and experiences. The teachers should in their preperation take every student in to consideration. To be able to investigate these subjets I prepared following questions:What does the concept of individualization in mathematics mean for the teachers?What does it mean to work with an individualized mathematics teaching?How does teachers individualizes teaching mathematics relative to high performing students?This study is based on a qualitative method with both interviews and observations.

During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of contaminated sites, MIFO, the site in Grötingen has been identified as a potentially contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.

Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.

In this literature review the characteristics of two free-floating macrophytes, water hyacinth   (Eichhornia crassipes) and duckweed (Lemna sp.), and two microalgae, Chlorella and Scenedesmus, have been examined regarding their suitability as efficient nutrient removers in the treatment of wastewater with high levels of nutrients and suspended solids from a biogas plant in Loudden. The needs required for the plants to be able to grow in wastewater and the amounts of biomass they can produce have also been studied. The results show that Chlorella is capable of a very high uptake of nutrients in photobioreactors with high nutrient loadings. With an ammonia uptake maximum value at 10900mg/m2/d Chlorella outshines the other organisms in this study. The test organism that performed the closest to Chlorella in terms of nitrogen uptake was water hyacinth with an uptake about 1602mg/m2/d.

Roughly 130 000 dwellings have been officially registered since Norway as of summer 2009 passed their bill ?Energimerkeforskriften? on energy performance certificates in buildings. The main objective is to decrease the total amount of national energy consumption by producing a methodology of calculation of the integrated energy performance of buildings as well as proposing cost effective measures to lower each building?s energy consumption. As the measures should not contravene nor be incompatible with the intended quality and character of the building, the ?Energimerkeforskriften? exempts buildings that due to their historical and cultural values are protected cultural heritage legislation. The current system offers a couple of professional certification alternatives, but when two online semi-automatic methods developed specifically for non-professionals are by far the most used, and since the methods of calculation primarily have focused on modern building materials and construction, the rest of the historical building stock stands literally unprotected by incorrect performance certificates and high-risk energy efficient measures. The objective of this thesis is to identify if the current Norwegian energy certificate system poses a threat to older buildings.

A quantitative survey of students in grades one in high school, where the aim is to find out what factors affected their upper secondary school. The survey is based on marketing, and looks to how to market a high school..

Statistics Sweden is an administrative agency that delimits built-up areas and produces statistics regarding them. The statistics provide information about the area of the built-up areas, their population number, number of gainfully employees working in the built-up areas, and of buildings. Now Statistics Sweden wishes to extend such statistics by producing a measure regarding how well developed the service is in each built-up area.This study is a contribution to this statistical improvement work and the purpose is to ? by employing geographical information systems and cluster analysis ? classify the Swedish built-up areas according to 1) service width and 2) service degree. A particular built-up area has a high service width if it has many different service functions, such as pharmacies, schools and grocery stores.

The study is based on a new approach on how Swedish healthcare is supposed to be controlled and organized. There is a renowned administration problem within Swedish healthcare, which seems to be an obstacle to exploit the resources to the fullest. The latest venture within the healthcare system is patient involvement, where the patients become co-producers of their own care, which aims to both improve and make healthcare more efficient. A few wards in Sweden have implemented this new approach whereupon the study intends to discuss the effectiveness and efficiency in some of these.The study is restricted to three wards, whereof two of these are inpatient wards and the other one is an outpatient ward, within the medical clinic in Jönköping County Council, which has implemented the patient involvement approach in their daily work. The methodology for this study is qualitative in its nature where a time study of personnel time allocation and supplementary interviews with managing nurses on the wards have been conducted.
