Optimering av skumdämpande additiver För användning i en lufttorkande vattenburen rostskyddsprimer

The development of defoaming additives is steadily progressing and there are therefore always new and improved additives on the market. Some modern additives provide the desired defoaming effects by themselves, in contrasts to previous additives that needed to be used in combination with other additives. The task of this bachelors thesis was to evaluate the possibility of using these improved defoaming additives, with the aim to find alternatives that give the system better defoaming attributes while, at the same time, using less of the primary products. The tests were carried out in the coating type Teknocryl Aqua Combi 2780. The coating is a waterborne air drying acrylat-latex/alkyd based coating that can be used for both single coat painting and primer.

Hantering av skadade styrstavar

The thesis was performed at Forsmarks Kraftgrupp AB in the department ofmechanical engineering, FTCM. Forsmark nuclear power plant has had problems with cracks in some of the controlrods which are placed in the reactor at Forsmark 3. To investigate the cause of this,material samples were taken from five of the damaged control rods. This sampling ofthe rods resulted too short rods to be transported in the shipping container to theinterim storage facility for used nuclear fuel in Oskarshamn. Control rods are crucial components in a nuclear reactor, regulating the reactoreffect by blocking or unblocking fuel rods. Control rods which have been in thereactor are always handled under water in order to protect against the radiation theyemit. The task was to design a control rod adapter that extends the control rod sotransport can be performed from Forsmark. The goal of the work was a complete setof blueprints so the control rod adapter can be manufactured and mounted on theshort control rods and then be transported to the interim storage facility. The work began with mapping of how control rods normally being handled from thereactor to the interim storage facility.

Markanvändning och ekosystemtjänster i en gradient från borealt till alpint landskap ? Vilhelmina Model Forest

Begreppet ekosystemtjänster kan användas för att tydliggöra värdet av landskapets funktioner och därmed underlätta kommunikation mellan markanvändare då olika intressen konkurrerar. Emellertid finns det få studier som inkluderar en kvantitativ eller kvalitativ värdering av ekosystemtjänster på landskapsnivå. I detta arbete har markanvändning och ekosystemtjänster studerats i ett landskapsperspektiv, med Vilhelmina Model Forest (VMF) som studieområde. Den övergripande frågan i VMF är hur rennäring kan kombineras med andra markanvändningsintressen, huvudsakligen skogsbruk. Syftet med studien var att göra en kvantitativ värdering av markanvändningsintressen och ekosystemtjänster.

Manufactured Destiny. Hur svenska medier håller balansen på bortaplan och huvudet kallt i stridens hetta

Titel: Manufactured Destiny - hur svenska medier håller balansen på bortaplanFörfattare: Johan LindahlInlämnat: 29 maj 2009Kurs: Examensarbete i medie- och kommunikazionsvetenskap, Institutionen för journalistik och masskommunikation, GöteborgTermin: våren 2009Handledare: Bengt JohanssonKursansvarig: Ingela WadbringSidantal: 50, inkl. bilaga (kodbok)Syfte: att undersöka hur balanserade och rättvisande svenska nyhetsmedier var i sin rapportering från presidentvalet i USA 2008Metod: Kvantitativ innehållsanalysMaterial: 115 artiklar från tre svenska dagstidningar under veckorna före valdagen 4 november 2008Resultat i korthet: Studien visar att det under de berörda veckorna fanns en klar övervikt avartiklar där demokraten Barack Obama framstod som en trolig vinnare, medan republikanskemotkandidaten John McCain var på väg mot en sannolik valförlust. Obama förekom otvetydigtoftare än McCain i både text och bild. Andelen positiva omdömen om Obama kan också sägas ha varit fler än för motståndaren, såväl från tillfrågade väljare, som från intervjuade inflytelserika personligheter och analyserande artikelförfattare. Om detta innebär en oskälig obalans i rapporteringen kan dock diskuteras, eftersom materialet åtminstone delvis stödde sig på opinionsmätningar och andra bakgrundsfakta för att underbygga slutsatserna.

Abrasiv nötning av polymerer tillverkade genom 3D-skrivning

Volvo Cars in Skövde manufacture and assemble Volvo engines. When attaching the ignition coil to all 4-cylinder engines, a special mounting tool is required. This mounting tool is currently manufactured from injection-molded polyoxymethylene (POM), a thermoplastic. It has been noted that the life span of the tool is shortened as a result of abrasive wear that occurs during the attachment process of the ignition coil.An investigation of the possibility of manufacturing the mounting tool with a 3D-printer is undertaken in cooperation with ÅF, a consultant to Volvo Cars. A literature study is first presented to introduce broader knowledge on the subject.

Millions of animals are annually affected by human activities; in the food industry, zoos and animal shows, clothes and shoes production, furniture and pharmaceutical industry, research, as well as pet and sports animal industry. Companies working with Corporate Social Responsibility, CSR, have become more common and within this area there are great possibilities for companies to work with animal welfare. In this study five companies were interviewed and 27 companies participated in a survey regarding CSR and animal welfare. The aim of this study was to investigate opinion and approach among companies towards implementing animal welfare as a part of their work with CSR. Furthermore the aim of the study was to investigate how companies may implement animal welfare. The result showed that the vast majority of the companies participating in the study works with CSR and the main part of the companies also answered that they have implemented animal welfare. The way of working with animal welfare varied among the participants; e.g.

The purpose of this investigation was to find out more about students? spontaneous ideas about properties and transformations of matter. Examples of matter chosen are such which students know about from everyday life and focus is mainly on the questions if students know that all matter has weight and that matter is preserved in transformations.The method used is semi structured qualitative interviews with individual students. Different experiments were carried out together with the students who afterwards were interviewed. However, the students show varying answers and no generalizations can be done.

Livscykelanalys av en gängtapp - Underlag och verktyg för att inkludera livscykelperspektivet i utvecklingsarbetet vid Dormer Tools AB

The aim of my thesis was to do a Life Cycle Assessment (LCA) of an average thread tap that is manufactured by Dormer Tools AB, and to create a practical model that the company can use in order to study other thread taps from an environmental perspective.The method of LCA is used to investigate the environmental effects of a product during its life cycle. This is a gate-to-grave analysis with focus on steel and thread tap manufacturing, coating procedure, use, waste management and transports. Three common coating types were compared separately. Steel manufacturing answers for the highest energy and raw material consumption under the life cycle of the thread tap. Its emissions contribute to global warming, acidification and eutrophication above others.
