The aim of this thesis is to look for signs of students? understanding of algebra by studying how they make the transition from arithmetic to algebra. Students in an Upper Secondary class on the Natural Science program and Science and Technology program were given a questionnaire with a number of algebraic problems of different levels of difficulty. Especially important for the study was that students leave comments and explanations of how they solved the problems. According to earlier research, transitions are the most critical steps in problem solving.

International organizations are important actors on the stage of world politics, and how these actors securitize the climate change issue is of importance for how it will be tackled by actors on global and national levels. The purpose of this study is to contribute to research on climate security discourses and how climate change is defined as a security concern amongst different actors. This study, in contrast to previous research, focuses on systematically mapping the definitions made by different international organizations by asking: whose security is at stake; who is responsible for responding to the threat; how is the nature of the threat defined; and what responses are suggested? By analyzing material consisting of a variety of documents and statements from five international organizations, I aim to identify differences between these actors ? in how the climate change issue is conceptualized from a security perspective. The result of the study shows that only one of the organizations shows clear elements of the national/geopolitical security discourse, while all of the other actors primarily use the human security discourse.

Both serum creatinine and measuring GFR can be used to evaluate renal function in dogs suspected to have chronic kidney disease (CKD). Although high creatinine levels usually indicate renal disease, normal creatinine levels can be present in dogs with decreased renal filtration. Measuring GFR is generally believed to be the most accurate way of detecting decreased renal filtration and scintigraphy GFR using 99mTc-DTPA has been found to correlate well with the ?gold standard? inulin clearance method.When measuring GFR by scintigraphy, 99mTc-DTPA is injected intravenously and radioactive decay of technetium gives rise to gamma radiation, which is registered by a gamma camera. Pictures and curves of radioactivity in the kidneys are generated by means of a computer program.

In the report parasites in the gastrointestinal tract and easily visible external symptoms of disease in capercaillie, (Tetrao urogallus), was taken into account. The study was based on results from the examination of 62 fresh faecal samples, collected in spring 2003, and postmortem examination of 22 frozen birds that were collected between 1999 and 2003. All of the samples principally were from the north of Sweden. In total, 4 species of parasites, but no significant symptoms of disease were found. In the faeces low levels eggs of the roundworms Capillaria spp. (125 epg) and Ascaridia spp.

The following thesis is a study of the forest history on the island of Ängsön-Marskär concentrating on the last three hundred years. The island is located in the administrative province of Stockholm, the local community of Haninge and it is situated approximately seven kilometres east of the island Ornö in the south of the Stockholm archipelago. The questions this thesis attempts to answer are: How where the natural resources on Ängsön-Marskär used through the centuries? How has the state of the forests developed since the 16th century? How will the nature develop onwards? The thesis is based on archival sources for Ängsön-Marskär and the surrounding areas. A field study was conducted where the entire island was investigated using an objective forest inventory method. The first map material existing over Ängsön-Marskär is from the year 1711.

The purpose of this study was to examine how school counselors in a specific municipalityviewed their work situation, if they experienced stress and how they would handle that stress.Five school counselors out of eight in the specific municipality participated in qualitativeinterviews where they could describe their feelings and thoughts. Their experiences wasexamined and analyzed with the theories of coping and empowerment. The results showedthat there were unhealthy levels of stress in the profession amongst the five counselors. It alsoshowed that the uttermost reason for the experienced unhealthy stress was the feeling of notbeing able to give as much time and help to the pupils as they want and need. The reason forthis was that an increasing number of pupils were, and are, experiencing unhappiness and arein need of seeing the school counselor.

The effects from a planned wind farm on the grid utility Gävle Energis electrical grid have been studied. The wind farm is planned to be built in the forest 15 km north of Gävle and will have 23 turbines with rated power from 2 to 2.5 MW, resulting in a total installed power between 46 MW and 57.5 MW. The grid connection will be made at 70 kV. The aim of the analysis was to determine what effects the wind farm would have on the power grid in the form of electrical disturbances (flicker etc.), need for new investment and raised operational cost. To allow the connection of the wind farm technical solutions (new lines, power stations and grid reinforcements) have been constructed.

This report treats two assignments that concerns the biofuel furnace at Billerud Skärblacka AB and how these assignments were solved. The assignments were: reducing the number of CO-spikes and tuning the overfire air control loop. To reduce the number of CO-spikes the possibility that skewness in mass distribution affects the number of CO-spikes were study. The skewnwss of mass distribution was controled and adjusted with two experiments. The conclusion that was made is that the skewness of mass distribution were not sufficient enough to affect the number of CO-spikes.

The purpose of this research is to investigate the group constellation that is, what thoughts, feelings and sensations that arise when students and pupils change groups. The study will also affect students and pupils knowledge of why they should work in groups. Their perceived security will also be something that this study is looking for.The main questions of this study are:How does students and pupils experience the phenomenon of "group replacement"?What is considered to work or not work in the new group formations?The method that is used in this study is based on six qualitative interviews with students and pupils from three different levels of education. The target groups are college and high school students.

In this paper we have looked closer on a car-retailer in the middle of Sweden. We have chosen to dig deeper in the different problems that can occur, related to the supply. Soon we realized that that the problems weren?t related to stock management. Through studying the whole of the company, we have identified reasons to why details aren?t in the stock.

This master's thesis aims to study the relationship between two publiclibraries and Berättarministeriet, a foundation that offers free writingworkshops for children in areas with high levels of unemployment. Theworkshops are located in spaces that formerly belonged to the libraries.Questions posed in this thesis are How can the relationship between thelibraries and Berättarministeriet be described?, Why did the relationship turnout differently in the two places? and How does the library see itself, inrelation to Berättarministeriet?The theories used are Ögland's taxonomy for relationships between librariesand local organizations, and Folkesson's theory on interaction betweendifferent professional groups, and this was studied through interviews. Theresults showed a relationship without much interaction, beyond a "handover"of children from one place to the other, with time and shortness of staff beingcontributing factors to the low level of collaboration. Regarding the differentrelationships in the two places the results were not conclusive, butnevertheless showed tendancies of issues in the legitimacy dimension, fromthe library towards Berättarministeriet.

The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. The forest also have great value and in Malaysia as in many other tropical countries large volumes are harvested which leaves great areas of degraded forest with little growth and biological diversity. Due to their low financial value these forests are often transformed and used for other purposes than forestry such as oil palm plantations. The trees are often transported out of the forest using large bulldozers. They are heavy which causes compaction of the forest floor and during transport the top soil layers are moved to improve mobility.

The aim of this study was to understand how evaluations are implemented and used in procured nursing homes for elderly. Our methodological approach consisted of a single-case study research. The case in this study was Växjö municipality. Three procured nursing homes for elderly were chosen in the municipality as examples of implementation and use of evaluation. The method for retrieving empirical data and the analyzing of it was based on triangulation.

This degree project studied surface waters on Kåbo Golf Course in Uppsala, Sweden, with the aim of determining the status of the water and how it is affected by the activities of the golf club, and to obtain suggestions of measures to create better conditions for the water environment on and around the golf course. The project forms part of the environmental protection work of Kåbo Golf Club, which is working towards achieving environmental certification from the Swedish Golf Association (SGF). The study is based on literature studies and quantitative and qualitative field studies of water on the golf course, with the focus on environmental factors identified as being important for the golf industry and on strategic environmental goals developed by SGF. The number of open water bodies in the Swedish landscape has substantially declined during the past 200 years, so it is important to save those that remain. This study showed that the surface water at Kåbo Golf Course is an important element in the surroundings since the area contains few wetlands, which can be a habitat for large numbers of species. The stream and ponds on Kåbo Golf Course also have the important function of serving as water hazards in the game and adding difficulty and variety to the course. Since Kåbo Golf Club wants its surface waters to look aesthetically appealing, extensive algal growth and drying up of ponds during parts of the year are regarded as problems.

This paper aims at describing and explaining the bi-and multilateral negotiations that are, and have been, taking place between Sweden's chief negotiator Allan Larsson and European countries, and within the EU institutions in Brussels, in order to seek support for the Swedish offer to host the European Spallation Source, ESS. It applies a case study method using political science theories ? governance and government ? and to a large extent information from the involved actors in the policy process. The paper also presents a constructive position, in showing how the negotiations on ESS can turn into a process leading to a decision on the construction of this research facility. ESS is negotiated in networks on bi- and multilateral levels consisting of European research representatives and financiers.
