Öppna problem i läroböcker för kurs Matematik A
The purpose of this essay is to investigate the presences of open-ended problems in the textbooks of high school Mathematics A. For practical reasons the study was limited to three textbooks and two topics, Fractions and Area & Volume. The Essay also describes the theory behind open-ended problems and why they should be used. I identify three criteria as a definition for open-ended problems. The study found that only 7,6% of the investigated tasks qualified, and met at least 1 criterion.

Hur skall den totala vårdkostnaden för en hjärtprodukt beräknas? : En fallstudie av tre hjärtprodukter vid Hjärt- och Medicincentrum på Universitetssjukhuset i Linköping
This thesis, in the field of healthcare logistics, has been carried out at Hjärt- och Medicincentrum (HMC) at the University Hospital in Linköping during the fall and spring of 2012/2013. The thesis is done by two students at Linköping University at master?s level within the framework of Industrial Engineering and Management.As Sweden's county councils should not make a profit or loss, it is important that the councils are aware of how much care processes cost. Kardiologiska kliniken at HMC in Östergötland?s county council is one of the clinics that are profitable.
Ny konsumtion av gamla kläder : ? En studie om konsumenters miljömedvetenhet och motiv till att köpa second hand kläder på Myrorna
The world?s consumption is increasing at an accelerating rate and it´s produced and consumed more goods and services than ever before. A large part of people's consumption consists of clothing that is bought and discarded increasingly leading to a number of environmental problems such as global warming, pollution, loss of biodiversity and the depletion of natural assets. One way to save the earth's resources is to buy used clothing, so called second hand, instead of new ones. The store chain ?The Ants? (in Swedish ?Myrorna?) has specializing in second-hand goods and sells, among other things, clothes.
Hållbar design för en bättre värld - med hemlösa i fokus
The aim of this project is to examine the needs and problems that exists amongst homeless people and to develop a solution that will help them in their everyday life. Since the homeless are a relatively large vulnerable group i Sweden, their everyday lives could be made easier in many ways.A clear definition of the target group is put together to create a good starting point. What state and help orginazations do to help the homelss and the society?s view of the homeless is also relevant and has been documented. Four personal stories have been put together to desicribe cases of clear problems existing in everyday life.Several interesting problems has been defined from the research and acceptance in the communtiy, desire to be seen and heard and a lack of confidence were the main needs.
Personer med utmattningssyndrom: : Finns det ett samband mellan subjektiv och objektiv kognition?
Research shows that people with burnout experience a high degree of impairments in a range of cognitive functions including memory, attention and concentration. The overall aim of the present study is to investigate whether there is a correlation between subjective estimates of cognition and cognitive performance with objective tests in people with burnout with a focus on working memory and executive functions. Three specific questions were addressed; First, what cognitive problems are described and to what degree? Second, is the performance of executive and working memory tests related to self-reported cognitive problems? Third, are the self-reported cognitive problems related to measures of psychological distress? The study included 77 patients, 65 women and 12 men, with a mean age of 43.48 years. The results show that patients with burnout perceive themselves as having significantly impaired cognition in everyday life, which is clearly evident on the basis of the self-assessment forms PRMQ and CFQ.
Undervisning i media : med fokus på elever med läs- och skrivsvårigheter
This paper is based on observations made in the classroom, interviews and studies ofliterature.The observations that I made during my practical training period made me believethat pupils with writing and reading problems succeeded more often with the methodsof teaching used in media education than with more traditional teaching methods.Through this study I hope to specify and define the factors that were the reasons for this. In doing so I wanted to show that you could adapt the teaching methods to reach more pupils with different kinds of learning styles.I have come to the conclusion that the following factors made the pupils with writing and reading problems succeed more often in subjects related to media education:Variety, time spent, the pupils? interests and the equipment used..
Klimatsimulering av ett kontorsrum : Hur de termiska stigkrafterna påverkar ventilationseffektiviteten
AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.
Uppskattning av Ytkurvatur och CFD-simuleringar i Mänskliga Bukaortor
By applying a segmentation procedure to two different sets of computed tomography scans, two geometrical models of the abdominal aorta, containing one inlet and two outlets have been constructed. One of these depicts a healthy blood vessel while the other displays one afflicted with a Abdominal Aortic Aneurysm. After inputting these geometries into the computational dynamics software FLUENT, six simulations of laminar, stationary flow of a fluid that was assumed to be Newtonian were performed. The mass flow rate across the model outlet boundaries was varied for the different simulations to produce a basis for a parameter analysis study. The segmentation data was also used as input data to a surface description procedure which produced not only the surface itself, but also the first and second directional derivatives in every one of its defining spatial data points.
Försöksmetod för automatisering av kvalitetssäkring av SKB
Within all industries, there is a change in working time required; this also includes the construction sector. However, the way construction sectors are differentiated is by not having been given the opportunity to be practiced or tested. The aim of this thesis that we have done in collaboration with the Concrete Industry was to investigate the possibility of developing an automated method for quality assurance of SKB at the site. The idea is to make the O-funnel to be more utilized and therefore ensuring that the appropriate concrete quality is provided which eventually would lead to a better development in the production process.The project has involved theoretical work and laboratory experiments. The theoretical work gave us a good foundation at the beginning of the project. After gathering the information and material, the laboratory experiments began by SCC in their laboratory in Hammarby. The collected data from the various laboratory tests formed the foundation for trying to relate measurements for consistency of SCC with each other and therefore find out how measurements from O-funnel varies with different concrete mixtures.
Kulturella och språkliga skillnader i globalt inköpsarbete
In the global society of today it takes more and more to become a successful purchaser. One part of this is to understand distinctions between different countries. The first and the biggest thing that you think about are the languages. Of course this is a big obstacle but there are also big cultural differences to be considered. According to Van Weele (2002) this is something that not, until these days, have been prioritized but today it is becoming more common in the industries.The biggest question we asked ourselves before the work started was how cultural and verbal differences affected the global procurement on Husqvarna.
Erfarenheter bland omvårdnadspersonal av att bemöta personer med missbruks- eller beroendeproblem på en akutmottagning : En intervjustudie
The number of persons with problems of abuse or addiction seeking care has increased during the last years in Sweden. Recent international studies show stigmatizing attitudes among nursing staff, which affect the treatment and care negatively. The purpose of this study was to describe experiences among nursing staff of treating persons with problems of abuse or addiction at an emergency department. The participants were six nurses and one assistant nurse who worked at an emergency department. The interviews were analyzed through qualitative content analysis.
En vampyr i sitt liv : En studie om elevers syn på gymnasieskolans arbete mot diskriminering, trakasserier och kränkning
The representative democracy has become weakened during the last decades. At the same time the United Nations declared at the Rio de Janeiro meeting in 1992 that environmental problems can best be solved by involvement of all concerned citizens in decision-making. The main purpose of this study has been to examine if citizens panels is a possible way to involve citizens in environmental decision-making and what the outcomes can be. Furthermore the study has investigated what the participation has contributed to environmental politics and how representative the results have been. This has been carried out by investigating the Piteåpanel in the municipality of Piteå by conducting interviews.The result of the study shows that the involvement of the citizens in the decision-making influenced the environmental politics of the municipality.
Frihet och jord : En studie av frihetens gränser för bönder, jordfattiga och trälar i landskapslagarnas samhälle
The aim of this study is to analyze how problems are represented within SOU 2008:27. Further more, the aim is to analyze how the new subject plan for history can bee seen as a product of this document. The method used, and the theoretical frame of the study, is based on Carol Lee Bacchi?s ?what´s the problem represented to be?? approach, which basic principle is that policies are filled with representations of problems and that these representations need to be examined. These problem representations are then themselves subject for scrutiny, the second step being an analysis of the texts presumptions and assumptions concerning view of man and perception of knowledge. The results show, among other things, that a problem representations can be found in the SOU; the school system is too vague and unclear.
Kvantifiering av föroreningstillskott från dagvatten inom skyddsområdet för Göta Älv : en simuleringsstudie med modellen SEWSYS
The river Göta Älv reaches between Vänern and Gothenburg and is the main raw water source for Gothenburg that supplies about 700 000 people with water. To protect and maintain a high water quality, continuously samples and water analyses are made throughout the river. In 1998 a protection area was founded between surte and Lärjeholm where the raw water intake is. This was made to increase the awareness of the importance to protect the water. However, there is a lot of contribution of untreated stormwater to Göta Älv within the protection area.Göteborg Water and Sewage Works commissioned this thesis where two areas, Tagene industrial area and Kärra residential area, with untreated stormwater outlets within the protection area are studied.
