Avsättningar i pappersmaskiner : Utbildning och förslag till processförbättringar

Deposits can be formed in the paper machine due to sticky materials from wood and recycled paper. These deposits get stuck on process equipment and cause the product quality to deteriorate and the efficiency of the paper machine is reduced. The purpose of this thesis is to increase the understanding about deposits among machine operators, and to suggest methods that can be used to reduce the amount of deposits formed in Bravikens paper machines.To fulfill the purpose of the thesis a pre-study, a literature review and interviews with machine operators and production staff, were carried out. These methods led to the planning and creation of an education about deposits for machine operators.The education about deposits for machine operators consisted of an interactive lecture to introduce the subject of deposits and a subsequent discussion. This approach was chosen to give the machine operators the opportunity to discuss their work situation on the paper machines related to their new knowledge about deposits.

Förskollärarens didaktiska val av material för barns fria lek : En undersökning om förskollärares tankar

Syftet med denna undersökning är att lyfta fram hur förskollärarna tänker i sina didaktiska val av lekmaterial i den fria leken. Dessa val kan påverka barns lärande och utveckling i den fria leken genom regler gällande olika materials användande. Genom material kan barn i sin fantasi omvandla ett material med ett specifikt användningsområde till något helt annat, då barn gärna transformerar material så de passar in i den fria leken. Dessa tankar baseras på det sociokulturella perspektivet.Metoden som används är intervjuer då utgångspunkten är att förstå och beskriva hur förskollärare tänker om sitt handlande, vår ansats utgår därför från ett kognitivistiskt perspektiv. Resultatet baseras på sex intervjuer av förskollärare.Resultatet som framkom i undersökningen var att samtliga förskollärare tänkte på att ge barnen fri tillgång till allt material i en tillåtande miljö.

Tillvaratagande och återanvändning av träbyggnadsmaterial : tjänstedesign för återbruk inom byggsektorn

The purpose of this Bachelor degree project is to design different types of services that can increase the amount of re-used timber within the building sector and by that means improve their environmental efforts. By examining how the sectors environmental work concerning recycling and re-using timber as a building material is getting on at present, conclusions have been drawn about what further could be done for improvement.The project has shown that there is a scarcity of information and statistics within the sector, but that there are efforts in progress to change this. Questionnaires have been sent to a number of companies working with demolition and utilizing re-usable materials in order to find out what kind of problems there are within the trade. Unfortunately the survey gave insufficient result due to the low reply frequency.It is obvious that active environmental work within the building sector is important and the knowledge acquired while working with the project has led to the design of three suggestions for services regarded as being of interest for improving the negative environmental impact caused by the sector:Suggestion 1 ? Sale of construction parts prior to the demolition of a buildingSuggestion 2 ? Re-utilization circulation when manufacturing buildingsSuggestion 3 ? Education in relation to the purchase of houses  The positive and negative qualities of the suggestions have been examined with SWOT-analysis and further adaptions and the results have been interpreted.

Ansvaret för tillämpningen av vissa familjerättsliga skyddsregler : Om gränsen mellan opartiskhet och etisk plikt som jurist

AbstractWorking as a lawyer demands not only legal skills, but also ethical ones due to the involvement with humans. The area of ethics is far from as regulated as the area of law is. The reasons for this are both historical ? as the area of ethics is, in comparison with the practice of law, a relatively new area, especially combined with the traditional work of lawyers ? and technical, since ethics is an area that seems difficult to regulate due to its adopting skills. Ethics looks different depending on which work area it addresses; who you ask; and in what situation it shall be enlightened.

KONSTEN ATT KONSUMERA - En kvalitativ studie om föreställningar, materialitet och identitet inom Every Day Carry

The purpose of this thesis is to study how today?s consumer society can be understood from ananalysis of the phenomenon Every Day Carry (EDC). The aim is thus to problematize the daily useof the artifacts that surrounds us and investigate how these can be understood as networks of humanand non-human actors, aswell as identity- and meaning-making practices in today?s consumersociety.The theoretical and methodical framework is built upon an eclectic variety of consumptiontheories,Michel Callon?s, John Law?s and Bruno Latour?s work on Actor-Network-Theory,Discourse analysis inspired by Michel Foucault, Ernesto Laclau and Chantal Mouffe and anethnographic methodology specifically adapted for online research.

Förpackningshantering i det dolda : En studie om hur den interna hanteringen kan synliggöras och förbättras.

Handling materials and packaging, which is the focus of this study, requires efficient logistics, both internally and between companies. To achieve an efficient material flow, good information systems, whose role is to collect, store, process and distribute information, are required. The assumption that packagings are handled in an efficient manner is currently not a matter of course, when many companies do not prioritize the internal management of the package.The purpose of this report was to investigate how medium-sized businesses working with distribution and handling of spare parts packaging can improve their internal management of packaging. In order to answer the purpose, we have used an abductive process and a qualitative data collection. The study had Logistic Center Ljungby (LCL) at Electrolux Laundry Systems (ELS) as a case company and two other respondents, Nibe in Markaryd and Enertech in Ljungby.

Utveckling av mobilapplikation

The company System Andersson is developing systems for controlling materials and production in industries. They want to add a new service, where parts of those systems are accessible through cell phones.In this paper we are investigating which technology are best suited for this kind of application. And then we describe how we are developing a prototype fort this application, based upon that technology. After investigating technologies such as Java ME, Microsoft Silverlight, and web applications we settled upon building the system as a web application, customized for a mobile environment.To build a web page which is readable by many different cell phones we use the markup-languages which are developed for cell phones. We put much effort in reading about the standards and recommendations for the mobile web, produced by the organizations W3C and OMA.

Analys och dimensionering av robusta kilspårsförband

This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.

Kan fogen bli bättre Fogar i Industriellt byggande

Fogar i industriellt byggande tar allt mer plats och det diskuteras idag omfogar på annorlunda sätt i jmf. med innan när man inte visste vilken betydelse de hade i hela konstruktionen.Idag tar man hänsyn till personer som bor i själva huset och derashälsotillstånd, eftersom det är lika viktigt att vi mår bra i våra hus som att konstruktionen håller längre och det är allra viktigast att vi försöker undvika att använda miljöskadliga material som påverkar vår hälsa och när det gäller fogar att vi undviker PCB som är cancer framkallande. Mer om PCB, bifogar vi i Bilaga 1.Tekniken utvecklas fort och vi måste anpassa oss till dagens utveckling påvarje område, IT, bilindustri, byggindustri som strävar mot industriellt byggande men för att lyckas måste vi ta hänsyn till allt som ingår i byggkonstruktionen, bland annat fogar som vi valde som tema att fördjupa oss i vårt magisterarbete.Vi har undersökt fogar angående? var de förekommer? hur de uppför sig vid olika klimatförändringar? hur de anpassar sig till andra materials förändringar (krympningar)? vilken roll spelar anslutningar (betongelement) till rörelser som uppstår i fogar? vilka material används? skador som uppstår? var felet uppträder oftastGenom dessa undersökningar har vi försökt förklara problematiken somuppstår och åtgärder som är nödvändiga att göra.Slutligen försöker vi peka på, vad det är som man närmare skall studera, närdet gäller fogar för att undvika sprickbildningar och materialbrott i anslutande byggkomponenter. Vi vill också visa på vilket värde ?en god kommunikation? mellan inblandade parter har.Eftersom våra studier har visat behov av kunskapslyft i fogteknik, bifogar viett teknikkapitel om fogar i Bilaga2..

Att förhålla sig till den nära historien - och planera för den avlägsna framtiden :

This thesis concerns the term contemporary history and its role in landscape architecture. Today?s contemporary history is defined as the planning and architecture connected to the 60s and 70s, in Sweden carried out as a large scale planning project called ?Miljonprogrammet?, which set out to build one million new residences in ten years. Initially, the term contemporary history and its complex of problem are examined. To deepen the picture of today?s situation, a historical review has been made, starting in early 1900s ending in 2000s concerning how different planning and architectural influences has varied through the years.
