Kontinuerlig temperaturmätning i bädden på gratevagnar
Luossavaara-Kiirunavaara Aktiebolag (LKAB) är en gruvdriftskoncern med järnmalmsbrytning som huvudsaklig verksamhet. En av produkterna tas fram genom att raffinera järnmalm till pellets vilket är en efterfrågad produkt vid ståltillverkning. Vid sintring av råkulor till pellets är temperaturen väsentlig för att få så hög oxidation som möjligt av magnetit till hematit och för att få rätt fasthet. För att reglera värmen bör temperaturen mätas bland råkulorna eftersom det är kulornas temperatur som är det viktiga. Projektet går ut på att undersöka möjligheterna att mäta temperatur bland råkulor på gratevagnar som åker genom en pelletsugn med ett permanent mätsystem. Här ställs höga krav på mätsystemet på grund av miljö, portabilitet och drifttid.Miljöanalyser gjordes för att ta reda på vilken påfrestning ett mätsystem bör klara av. Förslag om placering av mätutrustning framtogs genom kartläggning av miljön.
Fossilfri kollektivtrafik : En företags- och samhällsekonomisk kostnadsjämförelse av förnybara drivmedel för stadsbussar i Uppsala utifrån tre skattescenarier
Stockholms län är en expansiv region vars befolkning har vuxit kraftigt de senaste årtiondena och kommer enligt prognoser att fortsätta växa under en överskådlig framtid. Inflyttningen har inneburit att en redan hög efterfrågan på hyresrätter har blivit ännu högre. Trots en hög efterfrågan så är utbudet på hyresrätter trögrörligt och har inte hunnit i kapp. Detta har resulterat i att det råder bostadsbrist i stort sett i hela regionen.Det pågår ständigt en debatt bland experter, politiker och aktörer på fastighetsmarknaden om vad som kan göras för att åtgärda bristen på hyresrätter i regionen.En orsak till det låga byggandet av hyresrätter är att privata aktörer oftast betraktar den som en olönsam investering jämfört med bostadsrätten. Detta har hämmat byggandet enligt flera experter.
Mellan det sagda och det outsägliga : om socialsekreterares kompetens i barnavårdsutredningar
The purpose of this essay is to examine the concept of competence within the social services. More specifically it aims to find out how the social workers themselves look upon their own competence in social investigations concerning children. As the study was based on focus groups the main questions were vague at the beginning and were cleared later on during the group sessions.In three focus group interviews in three different municipalities in southern Sweden 11 social workers were asked to discuss this issue. The interviews were then thoroughly transcribed. In the data I identified 9 themes seeming to play a special roll in the discussions about competence: practice; experience; approach; intuition; responsibility; theories, methods and laws; reflection; resources and ethics; specialisation versus integration.The analysis made on these themes was based on two different kinds of perspective; one focusing knowing-in-action and the other focusing the organization framing the competence considered.As a conclusion the 7 first themes can be seen as a definition of the competence used in social investigations concerning children.
Biovetare, bibliotek och bioinformatiska resurser
Bioinformatics is an interdisciplinary scientific subject which connects biology, biomedicine and information science. Bioinformatics generates new biological knowledge by using computer methods and biological databases and can thereby play an important role for the understanding of diseases and be used for development of new medicines. The appearance of bioinformatics has thereby had a big impact on biomedical research.In this study, I have examined bioscientists' use of bibliographical databases, bioinformatic databases/web sites and bioinformatic tools and their needs of support concerning these resources. I have also examined which support the scientific libraries offer their users concerning bibliographical databases, bioinformatic databases/web sites and bioinformatic tools and have compared it with the needs the libraries think that the users have and the needs the users state that they have.The results from the study show that there is a wish for library support concerning bibliographical databases, bioinformatic databases/web sites and bioinformatic tools. The wishes of the respondents are in contrast to the libraries' view about bioscientists interest concerning bioinformatic databases/web sites and bioinformatic tools.
Om individanpassad matematikundervisning i praktiken : en intervjustudie med tre pedagoger i grundskolans tidigare år
Studies show that the performance of Swedish students in the subject of mathematics is to be considered somewhat average. The government has therefore decided to assist with extended project funding to schools on a local level in order to improve these results.Schools will, unlike before, practice teaching suited for the individual needs of students based on their previous experiences, knowledge level, language comprehension and their environment. This is also clearly stated in the Swedish school curriculum.My survey shows how three teachers in primary school actually work towards individualized teaching of mathematics and what methods they prefer. This survey also answered what these teachers considered to be the obstacles and opportunities with individualized teaching methods. The difference in approach of how to practice this has also been documented.The survey, based on interviews and class observations, have been analyzed and compared to previous research and theories in the field of teaching practices.
Effects of storage time, die channel length and moisture content on pellet quality of lodgepole pine (Pinus contorta Dougl. var. latifolia)
The use of Renewable resources is rapidly increasing in Sweden, especially the use of fuel pellets. Through pelletizing the energy content per volume unit is greatly increased and the pellets are more homogeneous with regard to moisture content, particle size and density compared to unrefined fuels like forest residues and chips. For further development of the Swedish pellet industry, the use of different assortments from lodgepole pine (Pinus contorta Dougl. var. latifolia) is of particular interest, mainly because of its high volume production.
LEAN produktuveckling : Ett arbete om kunskapsbaserad produktutveckling med fokus på tvärfunktionellt samarbete & lärande
Lean Product Development is a knowledge-based business concept in order to maintain high quality, meetcustomer requirements and to make product development more efficient. An important part of the processis to add a lot of resources at an early stage and execute the development as an iterative process betweendepartments exploring many alternatives thoroughly. The work focuses on how Lean ProductDevelopment is carried out and explores how to manage interaction between different departments andexpertise with regard to cross-functional collaboration and knowledge sharing i.e. learning.The information for the studies was gathered at a major Swedish company from two projects. The projectswere carried out as cross-functional and possible key factors for cross-functional collaboration wasidentified.The results have been correlated with theories of Lean, Product development, Lean product developmentand Learning.
Industriell symbios som affär : Hur kan ett återvinningsföretag facilitera utvecklingen av regionala industriella ekosystem?
Addressing increasing global environmental problems requires greater resource efficiency, and one way of working towards this is through industrial symbiosis. Industrial symbiosis means that companies collaborate through sharing of resources for collective benefits. The documented benefits of working with industrial symbiosis indicate that there is potential for companies to operate commercially with facilitation of industrial symbiosis. An interesting company to study within this context is Econova. Econova operates within the recycling and gardening industry and has been identified as a possible catalyst for industrial symbiosis.
Från passiv till aktiv strategi - Näringspolitisk förändring och handlingskapacitet i industrikommunerna Bromölla och Östra Göinge
Since the 1980's economic policies has become an important issue in municipalities and more resources are put into projects that are intended to have a positive influence on the local economic growth. From a theoretical perspective of regime theory and a model of local political economy, concerning the strategies chosen by the actors involved designed by Jon Pierre, the discussion points to the fact that it is possible to affect the local development. The municipalities discussed and compared in this thesis, Bromölla and Östra Göinge, have similar prerequisite for growth mainly due to their dependence to large industrial companies.In order to fulfill the aim of the thesis and examine the change in economic policies over time and between the two municipalities a comparative method is used. The creation of local governing coalitions is emphasized which makes efforts and intentions of individual actors crucial for the success of the local economic policies. Bromölla started their more active efforts in the area of economic policies earlier than Östra Göinge and has also come a bit further in the process.

Abstract Many researchers in social work believe that in today's society require the interaction between organisations takes place on social problems. This study examined the interaction between the police, social services and schools.The purpose of this study are as follows; the aim is to investigate the interaction between social services, the police and schools about young people aged 12-18 years who are at risk for abuse and crime.My questions are: How do the different professions interact regarding young people at risk for abuse and crime? How do they meet young people in their daily work? What obstacles can the different professions see in interaction? What effects do the different professions see in interaction?The study is a qualitative study conducted with semi-structured interviews. Respondents have been two from each organisation.The theory used in the analysis of empirical data is new-institutionalismen. New-institutionalism is a theory developed from organizational theories.
Bostadsförsörjning planlagd?
This thesis seeks to investigate the relationship between municipal policy for housing supply and the planning of new housing in Sweden. Through a case study of Göteborg municipality and a comparative content analysis of Göteborgs policy for housing supply and a number of plans featuring housing the analysis seeks to investigate the effect of policy for housing supply as a tool for securing the demand for housing in the Swedish municipalities. The thesis also seeks to discuss its findings using theory concerning the implementation of policy and the general planning situation for Swedish municipalities today. The result of the analysis shows that most plans fail to regulate most of the content suggested in the policy for housing supply, particularly regarding aspects such as pricing, type of housing and type of ownership. The result also points towards a relationship regarding the prevalence of municipal land contracts and compatibility to policy for housing supply as well as a connection between how extensive the plans are in their proposed land use and their compatibility with policy for housing supply.
Undersökning av processparametrar för optimering av sol-gelprocessen för produktion av kärnbränsle
A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.
Rekryteringsprocessen vid Svenska Spel
In the constantly changing working life of today, where emphasis on human capital grows stronger, the importance of recruiting and retaining good staff increases. Successful recruitment requires a first-rate recruitment process. In literature on recruitment recommendations for successful recruitment are presented. The aim of this study is to describe similarities and differences between these recommendations and Svenska Spel?s recruitment practice on the basis of a description of the recruitment process at AB Svenska Spel, and also to identify possible reasons for differences between theory and practice. To meet the purpose of this study literature and scientific reports have been studied. Interviews with five HR-specialists and four managers have also been conducted. The recruitment process is therefore described out of the employer?s point of view.
