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.

Förbättrad patientsäkerhet vid överlämnandet från operationssalen till intensivvårdsavdelningen

När säkerheten vid rapportering brister kan det få förödande konsekvenser. Inom intensiv- samt operationssjukvården bedrivs omvårdnad i en högteknologisk miljö där patienten befinner sig i en stark beroendeställning. Säkerhetsaspekten vid överrapporteringar är här mycket viktig. Syftet med litteraturstudien var att beskriva en patientsäker överrapportering mellan operation och intensivvård. Granskning av 14 vetenskapliga artiklar visade att kommunikationen mellan intensivvården samt operation förbättrades genom användandet av ett strukturerat rapporteringsverktyg.

Energikartläggning av ett 1970-tals lägenhetshus på Skarpövägen i Nacka kommun : Simulering av energibesparande åtgärder i ?IDA Indoor Climate and Energy?

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.

Luftvärmeväxlare med låg ljudnivå : Även i symbios med solfångare

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.

Queera Barnbiblar - En narratologisk & queerteoretisk analys av transformationen av berättelsen om David och Jonatan

As humans we transfer norms and values, which we are aware or unaware of, to the children near to us. These children embrace them, and the adult´s norms and values become the child's own ones. When a Bible story is going to be transformed into a children?s bible text it goes through shortening and simplification of the story to fit children´s bible edition. The adjustment will be unconscious and conscious choices that change the meaning of the text and the possibility of contextual interpretation.

Psykoterapeuters egen psykoterapi

Inledning: Det har funnits många aspekter av vad som påverkat psykoterapeuter i deras yrkesutövning.I forskning har psykoterapeuter uttryckt att den egna psykoterapin har varit en av de viktigas erfarenheterna i den egna utvecklingen som psykoterapeuter.Frågeställning: Hur har psykoterapeuter upplevt den egna psykoterapins påverkan på yrkesutövningen och har olika perioder av terapi haft olika inflytande?Metod: Denna studie har varit kvalitativ, i form av semistrukturerade intervjuer, med sju stycken psykodynamiskt utbildade psykoterapeuter. Förutom intervjuer har också tidigare forskning och litteratur i ämnet redovisats.Bearbetning av resultatet har skett i tematisk analys.Resultat: Psykoterapeuternas egen psykoterapi har påverkat dem inom flera områden i deras yrkesutövning. Främsta skälet till att de har gått i egen terapi har varit personliga svårigheter men också utbildningskrav.Diskussion: Psykoterapeuterna har upplevt att den egna psykoterapin har stort inflytande på olika delar av identiteten som psykoterapeut. De har inte varit lika lätt att skilja ut olika perioder av terapi och deras påverkan.

Transitioner i f-9-skolor : - en smidig ?röd? tråd eller en med svårlösta knutar

The aim of this study was to identify and make transitions in Swedish preschool-class-9-years elementary schools visible with a special-needs educational perspective. Transitions in focus were those between preschool-class and primary school, between grade three and four and the last between grade six and seven.In the 1960?th Swedish elementary school were devided into three levels; primary school, intermediate level school and upper level lower secondary school. Those levels were officially removed when the curriculum of 1994 was introduced. However, in some way such levels still exist, for example in organisation and structure of schools, the curriculum and teacher education.How did school leaders design transitions between levels and which tools were used? What kind of information was transferred to help children with special needs and what was the role of the special pedagogue in the transition process?The study was a combination of a quantitative and qualitative method, a questionnaire survey complemented with qualitative interviews with special pedagogues in three schools in a middle-sized Swedish town.The result of the study shows that schools in focus had a work plan.

Träning och manuell behandling för att minska impingementliknande symptom i skuldran hos idrottare? : En systematisk litteraturstudie

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.

Kylfläns till förbränningsmotor hos radiostyrda tävlingsbilar

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.

Intellectual Property Rights : A Barricade to Technological Development. An Ethical Analysis on the Less Developed Countries

Debate over Intellectual Property Rights ?IPRs? particularly patent and copyrights is mainly on forward-looking industries in computer software. As part of a trade deal reached in 1994, the member nations of the World Trade Organisation must adhere to a global agreement known as TRIPS, for the Trade- Related Aspect of Intellectual Property Rights.This study is to analyse the ethical conception of Intellectual Property Rights and in particular its implications on the developing countries in relation to TRIPS. The approach will be to analyse a broad philosophical theories of property to see if there is any justification for a software program to be treated as private property and also argue base on John Rawls two principles of justice in relation to TRIPS Agreement. Some reflections will be put on the use of open-source software by less developing countries.From the study it was asserted that, strong IPRs protection would hinder technological transfer and indigenous learning activities in the early stage of industrialisation when learning takes place through reverse engineering.

Varje mynt har två sidor : en undersökning om hur den kommande generationsväxlingen påverkar turismföretag

A central discussion within society and businesses today, is the change of generations in the business market which occurs within the upcoming years. A change of generations is unavoidable and a natural step in business. The challenge of the forthcoming reform is the large number of people leaving the labour market and the grand entrance of new labour; Generation Y. The characteristics of Generation Y differ from the older generation which enhances the challenges for the businesses to attract a new workforce. It may also be necessary for the organisations to adapt to the younger generation.
