The concept of function represents a major part of mathematics and becomes more significant in school during high school. Throughout history, it has been a difficult concept to define and may create challenges for contemporary students. This literature study aims to identify students' difficulties with the concept of function, as well as to account for how the definition of a function has evolved historically. The literature study has been conducted through database searches in ERIC, Education Research Complete and MathSciNet via EBSCOhost, as well as through chain searching. The study results in identifying that students' difficulties with the concept of function primarily include the graphical and algebraic forms of representation.

Användningen av biomarkörer inom medicin är ett viktigt verktyg för att ställa diagnos och fatta terapetiska beslut. Surfaktant protein D (SP-D) har visat sig vara en lovande biomarkör för perifera lungsjukdomar på humansidan och har därför även börjat studeras inom veterinärmedicinen. Surfaktant protein D är ett relativt lungspecifikt protein och produceras främst i perifera delar av lungorna, f.f.a av claraceller i bronkioler och typ II pneumocyter i alveoler. Det fungerar som ett akutfasprotein med liknande egenskaper som kollektiner och är därför viktigt för medfödda immunförsvaret. Förutom detta har det också visat sig vara grundläggande för normala lunghomeostasen genom att utgöra en beståndsdel i surfaktant. Mekanismerna bakom dess funktion i lungan är dock inte helt klarlagda. Eftersom SP-D är så basalt för lungan påverkas det ofta kraftigt vid perifera lungskador.

The number of LBOs in Sweden has increased during the last years and the current market trend is positive. MostLBOs involves private companies, but a few concerns public corporations on the national share market. In this thesis we will examine the conditions of a LBO of Cloetta Fazer AB. The purpose is to study existing conditions of Cloetta Fazer AB and to examine pros and cons with the deal. Based upon information presented in the frame of reference and in the empirical part, two cash flow valuations have been carried out.

Abstract    Objective: The aim of the present study was to investigate if inclinometer estimates of arm posture during paper mill work differed between periods of different arm visibility. The aim was also to identify strategies for and difficulties in assessing body-visibility on video. Methods: The study consisted of two parts, where part 1 aimed to investigate the validity of observation-based assessment of arm posture during paper mill work. Study 2 was a survey among people with experience in assessing the posture of paper mill workers from video. Results: The total time for the right upper arm visibility indicates that it was on average visible in 54%, partly visible 15 %  and not visible 31%.

This study shows how to plan a pond with an ecosystem which although it will have turtles living in it will not need to be cared. I will also demonstrate how this pond would be designed to work in the natural landscape on Mallorca. The background to the study is that I am interested to investigate how plants that we in Sweden are using as indoor plants are growing in their natural landscape and how to build a land-scape with them. The study highlights different cleaning-systems that can be used to clean a pond in a natural way. A comparison will be made between the conditions of an exterminated turtle-species which will live in this environment and a species that is easier to care for.

Vobbla Racing is a racing team who has an online sales department that is in need of an upgrade to be more efficient and easier to use. Before this study their present homepage was anything but structured. The products were sorted in an illogical order which made it difficult for the customer to find a wanted product. The customer had to summarize the products, transport sums and other costs. The order had to be e-mailed or phoned in to Vobbla Racing Produkter.

Test is an area in system development. Test can be performed manually or automated. Test activities can be supported by Word documents and Excel sheets for documenting and executing test cases and as well for follow up, but there are also new test tools designed to support and facilitate the testing process and the activities of the test. This study has described manual test and identified strengths and weaknesses of manual testing with a testing tool called Microsoft Test Manager (MTM) and of manual testing using test cases and test log templates developed by the testers at Sogeti. The result that emerged from the problem and strength analysis and the analysis of literature studies and firsthand experiences (in terms of creating, documenting and executing test cases) addresses the issue of the following weaknesses and strengths.

The purpose of this essay was to investigate whether speakers of different languages find different things difficult when learning Swedish. The results showed that the first language was not the only aspect that mattered when it comes to what difficulties the learners face. Also individual differences and the level the learner has reached in the language are important to consider. However, some differences between the groups investigated surfaced and this shows that the first language can infact effect what difficulties the learners will encounter.   .

The transition from having been under another country?s control to becoming a democratic country can, many times, pose difficulties, which has proven itself to be quite common. Estonia and Moldova?s processes towards a democratic regime are two examples of countries with varied success in the final transition phase.When the USSR (Soviet union) fell and collapsed in 1991 Estonia was well on their way from having a communistic ruling to a democratic one due to the fact that their democratic work had already begun a few years prior to 1991. After the collapse Estonia continued with their democratic work and in 2004 the country became a EU member state.

The fact that Sweden has changed from a homogeneous to a heterogeneous culture with multiculturalism as key word requires an intercultural approach in the community and school. The purpose of this study was to examine how teachers of maternal languages experience their teaching in school and what resources they have available from their employer and the municipality. What methods do the teachers in maternal languages use in their teaching at school and what resources do they have to their disposal? How do teachers in maternal languages use the perspective of intercultural education in their teaching and how do the teachers look on their future role in the Swedish school. To achieve this I have chosen the method to make depth interviews with 6 teachers of maternal languages and compare and relate the result to the theories about interculturality and the circle model, to official curricula and to existing literature in this subject.Teachers of maternal languages are very spread out, they work in several schools and sometimes even in different municipalities, during the same week.

The European Union is seen as democratic, and one of the criteria for a democratic decision process is that it must be fully transparent for the citizens. That is the only way for them to make their own decisions about political issues, and it is only possible as long as the citizens have access to relevant and reliable information. However, this is not always the case within the European Union, since it is often difficult to get a hold of different documents of the institutions, and since the civil servants to a great extent are forbidden to give away any information..

Introduction: To become acute ill and to be forced to seek treatment involves a difficult but also a vulnerable time for the individual. This acquires a good relationship between the nurse and the patient. At a surgical emergency ward patients with different diagnoses and trauma are treated. What distinguishes this specific type of ward is that care often occurs in a rapid rate and as a patient the environment may be experienced as stressed. The relationship with the nurse at the ward establishes a foundation for how the patient experiences the health care.

COPD (Chronic Obstructive Pulmonary Disease) is one of the most widespread lung diseases today and is a growing cause for suffering and mortality worldwide. It is considered to be the third leading cause of death in the near future. Smoking is the most important risk factor for this disease and about 50% of smokers develop COPD. The purpose of this study was to mediate the experience of not being able to stop smoking described by persons diagnosed with mild or moderate COPD. The study involved five women and five men.

The aim of the study was to examine individual staff experience and management of threats and violence in the acute psychiatric department for children and teenagers in Uppsala. Previous research shows that the experience of threats and/or violence is individual, and that it is difficult to distinguish between these concepts. Research shows that it is particularly vulnerable to work in psychiatry when mental illness is a cause when threats and violence occurs. Threats and violence can result in different consequences for the individual. The study is based on qualitative interviews and the material was collected in the autumn of 2012 at Akademiska sjukhuset.
