This thesis has been performed at Uddeholms AB with the purpose to investigate theparameters affecting the formation of inclusions during the manufacturing of a low carbonmanganese-steel.A follow-up, steel and slag sampling and evaluations in microscope have been done for a totalof five heats.The results for each heat have been evaluated in relation to the theory from the literaturesurvey and suggestions for changes in the process to reduce the amount of inclusions whichhave a negative effect on the steel quality have been given.The project extends over a large process where many parameters affect the formation ofinclusions. However, a tendency that a higher addition of alloys seems to increase the totalamount of inclusions before and after the vacuum degassing is seen.The majority of the studied inclusions seem to approach the composition of the top slag aftervacuum degassing. Ladle glaze may cause the inclusions which had a different compositioncompared to that of the slag.A high or low ladleage together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted material.In machined material so called stringers were found. The main composition of those stringerswas pure alumina. Inclusions with a composition of pure alumina were not found in the liquidsteel, thus the pure alumina inclusions must be formed during the casting.

Knowledge is today one of the most important resources for an organization to handle. But knowledge can also be difficult for organizations to manage. The internet is still growing and new tools take form that allows users to effectively share information. The purpose of this report was to describe how organizations can make use out of internal social media to facilitate knowledge management processes. Three issues involving mapping, coding and dissemination of knowledge to were produced to answer the thesis. The study was limited to examining the identification, coding and dissemination of knowledge through the internal social media plattformen, IBM Connections. The theoretical framework emphasizes how social networks can promote knowledge sharing, how a knowledge mapping can promote knowledge dissemination and sharing, how knowledge can be stored in data sources and how important interaction is to spread awareness. The theory has been supplemented by descriptions of how the system IBM Connections works. Surveys were conducted on four companies that use IBM Connections as an internal communication plattformen. The four companies were selected to illustrate how they use the plattformen of knowledge management processes and we chose to interview the people who were responsible for the introduction of the plattformen. The study identified several similarities between the different companies and that although there were some technical and cultural recalcitrant units against this new type of system within the organization so favored IBM Connections knowledge in several ways. The built-in search automatic created a map of knowledge through the plattform's user profiles. Saved files and documents could be found even after the employees left the company, which encodes knowledge into the company knowledge resources. The opportunity to interact with one another, often over great distances, favored the sharing of knowledge. A comparison with the theoretical framework provided us with the conclusion that internal social media can be used in several ways to Knowledge management through automated knowledge maps, the ability to store knowledge within the company and to communicate knowledge across functional and geographical boundaries in interactive discussions..

This study has been carried out in the spring of 2014 on behalf of PQR Consult AB in Stockholm. The aim of the study has been to analyse the energy usage of the building Skarpövägen 1 in order to explore the possibilites of saving energy by using appropriate equipment. These possible solutions have been simulated by using the programe IDA Indoor Climate and Energy, combined with a life cycle cost analysis. The laundry building, Skarövägen 23, has also been analysed due to its high amount of energy usage. The result of the energy analysis showed that the energy usage was much higher than the energy declaration.

Rapporten handlar om ett examensarbete omfattande 20 p som är utfört för Thermia AB i Arvika. Uppdragsgivaren ville få fram förslag på möjliga åtgärder som kan minska ljudnivån från en luftvärmeväxlare. För bra helhetsbild av projektet, läs även kapitel: 6.Värmeväxlaren ingår som en komponent i ett värmepumpssystem, Thermia Aer 5, som använder uteluften som värmekälla. Huvudmålet med projektet blev alltså att undersöka och utvärdera ljudbildningen från värmeväxlaren samt att komma fram till olika förslag på möjliga åtgärder som har potential att sänka ljudnivån. Värmeväxlarens förmåga att uppta energi fick ej heller försämras.I projektets slutskede tillverkades det också en enkel prototyp på ett av designförslagen där den störande ljudnivån blev lägre.

The following essay is a study of the theatre-play Min Arm, a translation and performance by Per Lasson for Fria Teatern in Stockholm 2009-2010. Actor, director and playwright Tim Crouch wrote the original script My Arm in English in 2003.With basis in intermedial theory, as defined by Jörgen Bruhn, as well as Hans-Thies Lehmann?s theory on post-dramatic theatre this study investigates the meaning-building processes in Min Arm as a theatrical performance. Concepts of the difference between stage play and performance text are borrowed from and inspired mainly by Eli Rozik?s Generating Theatre Meaning.

The ISO 9000-series is a set of quality standards created by the International Organization for Standardization. The series is intended to provide guidance to companies in the process of deploying an effective quality management system. The series includes the requirements standard ISO 9001. This standard contains requirements on how a quality management system should be designed and how companies generally must work with quality issues. When a quality management system is introduced, if wanted, a quality certification can be implemented.

The purpose of this work is to study a circulation project in Enköping municipality, where the society?s rest products are used to make beneficial products. In Enköping the rest products from waste treatment plants and private sewers are used to fertilize and irrigate Salix plantations that later are harvested and burned at the local combined heating and power plant, ENA Energy AB, to produce electricity and heat. Possibilities to apply this kind of project ona municipality in Russia are also explored.Guryevsk municipality in Kaliningrad region was chosen since there is a need to improve energy systems and reduce emissions to water and air. This municipality strives to become environmentally friendly.

AimThe purpose of this study is to investigate whether there is scientific evidence that exercise and/or manual therapy can improve function, in terms of increased mobility and strength on shoulder impingement-like symptoms among athletes. Another aim is to investigate whether these interventions can reduce shoulder pain.MethodA systematic review was conducted in the databases PubMed, CINAHL, PEDro and Amed. A total of thirteen articles were selected for further review and compilation. They were then graded for level of evidence according to the PEDro scale and the Swedish Council on Technology Assessment (SBU).ResultsThe systematic review shows that there is strong scientific evidence that acupuncture and heat can reduce pain in athletes diagnosed with supraspinatus-tendiopathy. There is limited scientific evidence that exercise increases strength, limited scientific evidence that stretching increases mobility and insufficient scientific evidence that a combination of treatments, with both exercise and stretching, reduces pain and increases function in overhead athletes.ConclusionsExercise and manual therapy can reduce pain and/or improve function in terms of increased mobility and strength in athletes with shoulder impingement-like symptoms.

Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.

Inom Radiostyrd Bilsport tävlas det med ett antal olika klasser som drivs av 2-taktsförbränningsmotorer. Dessa blir mycket varma och måste kylas av. Det sker med hjälp av enkylfläns som är monterad ovanpå förbränningsrummet, och som kyls av fartvinden.HP Hobbyprodukter har frågat oss om vi kan hjälpa dem att ta fram en egen kylfläns åt dem.Eftersom det ofta förekommer ovarsam behandling i tävlingssammanhang, är det ett krav attkylflänsens ska tåla detta. Den måste även avleda värme från förbränningsrummet, motorblocketoch övriga motorkomponenter effektivt. Ett önskemål är att kylflänsen ska ha ett unikt utseende,så att den är lätt att känna igen ute på banan.Arbetet har inriktat sig på prototypnivå.

This study focuses on the Nordic model of Extended Collective Licenses (ECL) and how this model can be used in the process of digitalising and publishing archival material such as photos, letters, maps or films. The question that this study aims to deal with is what advantages, and disadvantages, there are for archives and copyright holders when an ECL is being used. To help answering this question the ?theory of the knowledge commons? has been applied. The research question has been answered through a text analysis based on legal texts including Swedish law.

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.
