Parameterstudie av inneslutningsbildning och utvärdering av processföring för tillverkning av plastformsstål
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.
Analysis of CD4+ and CD8+ T-lymphocytes : A comparison between EPICS XL and Celldyn Sapphire
Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.
LEAN i ankomst och kontroll : Processkartläggning av ankomst och kontroll av material på Sanmina i Örnsköldsvik. Syftet är att genom analys identifiera slöseri i processen och genomföra förbättringar som eliminerar eller minskar störningar
This report is the result of a thesis at the company Sanmina in O?rnsko?ldsvik. The thesis is the final work at the mechanical engineering program at Umea? University.Sanmina has in 2015 launched an initiative to ensure that all sites are using LEAN principles and tools to enhance their business. As part of the plan for the LEAN-work, an LSS (Lean Six Sigma)-project has started to study the company's receivehall and inspection.
Inlandskommunens digitala klyfta : En kvalitativ studie om hur Vilhelmina kommun kan nå alla invånare
This surveys hypothesis is based on the notion that all citizens have the right to access information of the municipality they live in. The aim of the study is to examine how residents of Vilhelmina municipality take note of the current information, and also how they would proceed to access information in the future. In order to conceptualise the results these following theories were used: digital divide, digital immigrants, digital native, uses and gratification theory, social capital, communications strategies and two-way communication. The survey is conducted with four focus group interviews and one separate interview with a person working at the municipal office. The focus groups were divided into age categories in order to see the similarities and differences between the groups' media habits and preferences of future communications.
Byggnader för arbete och fotboll : Kanal 5, Stockholm. Canon, Solna. Swedbank Stadion, Malmö
Examensarbetet utgörs av en sammanfattning av tre genomförda nybyggnadsprojekt. Foton, ritningar och skisser visar hur arkitektoniska koncept omsatts från vision till verklighet. Gemensamt för projekten är att målbilden varit inriktad på nytta, identitet och mervärde. Kanal 5 i Stockholm är en mindre glasbyggnad som blivit en symbol för omvandlingen av ett helt innerstadskvarter, där verksamheterna ändrats från industri och hantverk till arbetsplats för idéprojekt och mediaproduktion. Byggnaden fungerar som huvudentré till äldre lokaler som renoverats. Stadsutveckling.
Ockupanter och gerillor, kort sagt en hel del att tänka på
Uppsatsen är inriktad på den militära delen i upprorsbekämpning och tar sin utgångspunkt i två stycken militärteoretikers teorier inom ämnet. Teoretikerna är John Mackinlay och David Kilcullen, som under 2009 utkom med varsin ny bok inom området, The Insurgent Archipelago samt The Accidental Guerilla. Den metod som arbetet vilar på är kvalitativ textanalys. Syftet med uppsatsen är att undersöka i vilken utsträckning som teorin och doktrinerna stämmer överrens. Därför har först teoretikernas syn på hur en utifrån kommande intervenerande styrka påverkar lokalbefolkningen analyserats.
Akta er för dörrarna - en observationsstudie av dörröppningar i en hybridsal
SUMMARYPrevious research has shown that there is a connection between the doorways and postoperative wound infections. Despite recommendations from Socialstyrelsen and the individual hospitals' PM there is still high traffic in the operating theatres. In a hybrid theatre environment combined X-ray techniques of surgery, resulting in it being further two categories inside the operating theatre. This may generate an increase in traffic flow. The study is a prospective, non-participant observation study conducted in the spring of 2013 at a university hospital in western Sweden.
Hur tron finner ankarfäste. Pastorers informationssökande i sin andliga tjänst
This Master?s thesis concerns the information behaviour of pastors in nonconformist churches (especially new evangelical and Baptist church communions) in Sweden in their spiritual service to the local parish. The thesis also looks into how the information flow functions in the pastors? context and why the information need appears as it does. The theory used in this study is contextual analysis based on Buckland?s, Weber?s and Patrick Wilson?s theories on authority and power structures.
Ingen spaning - ingen aning - En studie av vilka nyckeltal som ABB AB kan använda sig av för mätningar av incident management processen
Dagens IT?organisationer står inför många stora utmaningar. Företagens ITinfrastrukturerblir allt mer komplexa då företagen implementerar många olikasystem och applikationer under kort tid utan att avveckla befintliga system ochapplikationer.Syftet till att man investerar i IT?tjänster är att de ska generera ett värde iorganisationen och på så sätt bidra till att affärsmål uppnås. Det som många avföretagen missar är att mäta hur deras IT?tjänster påverkat organisationeröverlag.
Att placera eller inte placera... : En studie om socialsekreterares handlingsutrymme i ungdomsärenden
The present study deals with the scope of action available to a social worker when analyzing, assessing and proposing measures regarding young persons experiencing social problems. The interest in the subject area emanates from the fact that the number of youth placed in different forms of round the clock out-of-home care in Sweden increases, whereas research in the subject shows that such placement gives few positive results and sometimes even has negative consequences for their development.The study investigates how the preconditions of the social worker influence their scope of possible action, in particular as regards their place of work, the situation of the individual dealt with, and the profession itself being one based both on scientific evidence and knowledge gained by experience. Lipsky?s theory on ?street-level bureaucracy? and Hasenfelds theory on human servicing organizations form the theoretical framework of the present study. The empirical input comes from interviews with focus groups of active social workers.The analysis of the interviews shows that social workers generally feel that they have a broad scope of action as far as the regulatory framework and office management are concerned.
Kommunikation i dubbel bemärkelse : Enkätsstudie av barnfamiljer och SL:s digitala plattformar
As a result of a successful human development around the world an extensive urbanization of societies are taking place that are networked in various ways. In these networks, increased travel and digitization are central where individuals and organizations converge in a constant and immediate wireless and mobile technology flow. An example of this is Stockholm and its public transportation company Storstockholms Lokaltrafik (SL). Although most participate in most of the network society, SL is struggling with an audience that seldom travel with them: families with children. We intended to find out how the communication of SL´s digital platforms could get families to travel more with public transportation.
Böndernas vägar till Bryssel, många och långa men värda att gå. En studie om svenska jordbruksintressens möjligheter att påverka den gemensamma jordbrukspolitiken
In this essay, I investigate Swedish possibilities to influence the Common Agricultural Policy of the European Union (CAP). After having summarized my findings, I try to explain the structure of influence by using Multi-level governance theory.Ten years have passed since Sweden joined the Union, and many changes have followed in the agricultural sector. By investigating the small country of Sweden's possibilities to influence CAP, I hope to be able to get a notion of the possibilities to influence the EU in general. The essay examines four possible paths for agricultural interests to influence the policy process in Brussels:* Through elected representatives of Sweden in the European Parliament, the Council of Ministers and in the Swedish Parliament* Through subnational institutions, such as the local authorities and regional representatives.* Through the Swedish Agricultural Office* Through the Swedish pressure group within the agricultural area, LRFThese four groups all have very different channels to the policy process on agricultural issues. The differences are mostly in terms of decisive power or advisory power and institutional contacts or lobby contacts.
Textilindustrins avloppsvatten och avloppsslam ur ett miljöperspektiv : Underlag för internationella riktlinjer inom projektet Sweden Textile Water Initiative
The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.
Entering a new market ? A model for evaluating a new commercial real estate market
The development for Skanska Commercial Development (SCD) during the last years has been positive on all markets and Skanska therefore plans on expanding their activity. Central and Eastern Europe has had a considerable economic development, what is assessed to continue during the next following years. Bucharest is one possible alternative in the CEE for a new establishment by SCD. However, the investigation before an entry is a process with many factors that need to be taken into consideration. There are today no models on how and what a developer as SCD should evaluate in terms of opportunities and risks on a possible new market.
Ekonomiska sanktioner ur ett sjömaktsteoretiskt perspektiv
Fleets have the ability to affect an adversary?s use of the seas for transportation. Nations have in numerous occasions exercised this power in order to ravage their opponent?s trade in times of conflict with the purpose of diminishing their military might. Great naval thinkers like Mahan and Corbett have described this use of seapower during conflicts in great depth but theories regarding the use of seapower to affect a nation?s peacetime economy in order to achieve limited political goals is lacking.
