Utökade tillämpningsmöjligheter för turbinlösning i våtpartiet hos tissuemaskiner : Konceptförslag som möjliggör tillämpning av turbinlösning för maskiner vars banbredd är bredare än 2,9 meter
AbstractThis thesis is the final part of the Innovation and Design Engineering Programme (180 ECTS credits)at the Faculty of Health, Nature and Engineering Science at Karlstad University. The extent of thisthesis is 22.5 ECTS credits and has been performed independently by Hannes Jernberg during thespring of 2013. Metso Paper Karlstad AB is the task maker of this project, and Arvid Johansson is thecompany Representative. Metso Paper Karlstad AB is one of the world leading developer andmanufacturer of tissue paper machines.In the current situation, the company has developed and patented a power management systembased on a Cross Flow Turbine. The current construction is limited to a paper width of 2.9 meters.The company wants to take advantage of all the opportunities provided by the patents, to develop aturbine solution paper machine with a paper width that is wider than 5.5 meters, and give the abilityto manufacture paper for lower energy consumption which is an important part of the production asit is very energy intensive.Problems arise with the increasing length of the turbine, ultimately resulting in that the deflectionbecomes too big and that the momentums, due to the increased torque the turbine blades breaks.By applying the design process, this work has resulted in a number of potential solutions to theproblem.
Förvandling : från verklighet till fiktion
The purpose of this study is to describe some primary school teachers understanding of language development and approach of first and second language speakers with Arne Tragetons Writing to reading, for pupils in early ages.By using a qualitative method with interviews and participant observations and informal conversations, the basis for the survey was collected. Four teachers in three schools participated. The proportion of second-language pupils at each school was 35%, 17% and 0%. My theoretical starting point in the study was the hermeneutic research tradition, which has been used to interpret and understand the collected material. Theories of behaviorism, constructivism and socio-cultural perspective has been used in the analysis part of this study.
Inventering av tillgängligheten i Bilbergska huset.
Akademiska Hus owns and manages the university facilities in most university towns in Sweden. Bilbergska house in Örebro was built in 2008 by Akademiska Hus, and designed by White Architects. Today's buildings must meet accessibility requirements determined by Swedish Board of Housing, and it is the developer who must ensure that they are fulfilled. Swedish Board of Housing requirements are often vaguely written and interpretation space is large.This report aims to investigate how much of the requirements which are set towards the University and landlord Akademiska Hus are being achieved. This is done by studying the requirements that are set.
DFM för Lasersvetsning
The purpose with this thesis was to develop a designguideline which will simplify the development of new products that will be laser welded. The need for this thesis has come forward from the quality problems that Volvo Construction Equipment, Components Division is having with their laser welding manufacturing unit. The reason for the problems emerges from the bad communication between the development unit and the manufacturing unit within the company when the products produced today was developed. This resulted in products that were hard to and in some cases almost impossible to weld. To avoid these problems from occurring again it was needed to gather the experiences within this area and compile it and present in a brief a pedagogical manner. The information for the groundwork of our results has been gathered by interviews of several key persons in Volvo Construction Equipment, Components Division.
Vindfällning i naturliga och skapade bryn och kanter :
The aim of this work was to study if the edge of the forest is more resistant to heavy winds than the trees located further in from the edge, and how this edge effect changes between different types of tree species and site types.
The data was collected from an electric power line going from the north to the south of
Sweden. The mean value of the clearcutted area around the power line was 120 meters. The
main direction of the storm in January 2005 was west-southwest and thus the power line was a perfect place for gathering a large data set.
The main parameter studied was the damage frequency at the edge of the forest compared to
the trees located further in from the edge (up to 100 m from the power line). Tree species mixture, soil moisture class, soil type, topography, stand height, stand height of the stand on the other side of the power line and wind exposition was estimated.
The results showed a distinct edge effect. The edge of the forest had clearly lower damage frequency for all tree species.
A marked difference was observed between tree species and damage frequency.
Barn i behov av särskilt stöd - pedagogers bemötande i förskolan
Mitt mål som förskollärare är att alla barn ska ha möjlighet att utvecklas till självständiga individer. För att kunna uppnå det måste man som pedagog ha kunskapen om barns olikheter. Alla barn har behov men det är behoven som är olika. Ibland krävs det att man ändrar i miljön, ibland behöver den vuxne stöd och handledning i sitt arbete och ibland behöver pedagogerna till och med kompetensutveckling kring det aktuella ämnet. Detta behövs för att alla barns behov och förutsättningar ska tas i beaktande.

Samverkan mellan totalentreprenör och projektör i stora byggprojekt
As a result of the so called ?Million Program? between the years 1965 ? 1975 the design-build contract had its breakthrough in Sweden. Since then, the contract form has become increasingly common and now holds a strong position on the Swedish market. In design-build contracts it?s usual that the design and production time is overlapping.
Naturhänsynen i FSC-standarden : vetenskap eller gissningar?
The Swedish FSC standard (Forest Stewardship Council) is a level standard used to certify forestry. All the major Swedish forest companies are using the FSC standard, and approximately 50% of the Swedish forests are FSC certified today. In the essay six items within the chapter on environmental issues and biodiversity are examined: the proportion of protected forest, the proportion of annually burnt clear-cut stands, the number of trees with large diameter, the amount of dead wood, the proportion of deciduous trees within a stand and the proportion of deciduous-dominated stands. The FSC standard states a level for all items, and the purpose of the essay is to analyse whether these levels are supported by research within the field of conservation biology. The validity of the levels of the six items is them discussed to evaluate whether changes are required to the next revision of the FSC standard.
Membranbioreaktorteknik- en framtida lösning på Lundåkraverket? : Membrane bioreactors- A future solution at Lundåkra wastewater treatment plant?
Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.
Historien längs tuvor och slingriga vägar : En jämförande studie av tematisk och kronologisk undervisning i historia för gymnasieskolan
In the following study the author compares two methods of teaching history, the thematic approach and a more traditional chronological approach. Aiming at distinguishing the perceived notions of strength and weaknesses of each method, from the perspective of teaching, the author uses semi-structural interviews with four teachers in order to shed light on the reasons why each method is chosen. The perceptions of the thematical and chronological method in teaching history are further compared with the result in students? grades. The result shows that the thematic method is perceived as being better at teaching the student about causality and different understandings of changes in history, which would have positive impact on higher grades.
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.
Koma som konst
In my work as speech and language pathologist I often meet people emerging from coma andtheir experiences intrigue me. Coma is an eluding human condition that offers a challenge formodern science and our view on body and mind. In my Master project in Creative Writing Iwanted to try to enter this zone that is so hard for a clinician to reach: the personal experienceof being in a coma. By writing HUSK MIDAS I have tried to create a realistic fiction based onresearch on coma state and real-life stories of people waking up from coma.In my exploration of the coma state I found that lucid dreaming is common apart fromdreaming, many patients experience sensory inputs like sound and touch which aremisinterpreted and woven into dreams and creating a feeling of confusion and fear.Coma is a frequent theme in literature and film but is often depicted unrealistically andmisleadingly. A few works like Artur Lundkvist?s Journeys in Dream and Imagination andthe film The Descendents by Alexander Payne show a more reality based fiction.

Level-Up! : En uppsats om spelutvecklares väg till ökad autonomi
Vår uppsats fokuserar på data- och tvspelsbranschen med en inriktning på relationerna mellan spelutvecklare och spelutgivare. Bakgrunden till uppsatsen och studien bygger på att maktbalansen mellan spelutvecklare och spelutgivaren faller i favör för spelutgivaren som ofta kontrollerar både finansiering och distribution av en spelproduktion. Detta skapar en situation där spelutvecklaren, som står för den skapande delen av en spelproduktion, har liten till ingen kontroll över sin egen verksamhet. Denna balans håller på att förändras genom uppkomsten av nya finansierings- och distributionsalternativ som tillåter spelutvecklaren att förbigå spelutgivarens inblandning i spelproduktionen. I vår uppsats har vi valt att undersöka hur folkfinansiering, digital distribution och mun till mun-marknadsföring påverkar spelutvecklares autonomi.
