  3. 2. International large-scale assessments and mathematics textbooks in a curriculum reform process : Changes in lower secondary school algebra in Sweden 1995–2015

    Författare :Kristina Palm Kaplan; Johan Prytz; Kajsa Bråting; Astrid Pettersson; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; curriculum reform; algebra; textbooks; international assessment; TIMSS; secondary school; test validity; student achievement.; Curriculum Studies; Didaktik;

    Sammanfattning : Reforming a curriculum entails more than simply launching new steering documents: it includes the development of new materials, evaluation of reform and identification of needs for further action. Drawing from algebra material surrounding the 2011 Swedish curriculum reform, this thesis contributes to understanding the process of curriculum reform concerning mathematics textbooks and international large-scale assessments.

  4. 3. Studies on the Recovery of Secondary Antimony Compounds from Waste

    Författare :Toni Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Morphology; Thermolysis; Leaching; Municipal Solid Waste; Zinc; Metal Oxide Varistor; Cementation; Fly Ash; Recycling; Antimony;

    Sammanfattning : The global supply of antimony is dominated by one country which has led the European Union to classify antimony as a critical raw material. Other than the rare-earth elements antimony has the highest supply risk. Therefore, a feasibility study on the recycling of antimony and antimony compounds is of great importance. LÄS MER

  5. 4. Recycling of TiO2 Pigments from Waste Paint: Process Development, Surface Analysis, and Characterization

    Författare :Mikael Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Recovery; Paint; Titanium dioxide; Waste.; Municipal solid waste handling; Pyrolysis; Pigment;

    Sammanfattning : Pigments are commonly used in paint, plastic and paper products and titanium dioxide (TiO2), the most important white pigment, accounts for approximately 70 % of the total volume of all pigments used today. Minerals containing TiO2 are relatively abundant in the earth’s crust. LÄS MER

  7. 5. Thermophysical Properties of Aqueous Solutions Used as Secondary Working Fluids

    Författare :Åke Melinder; Björn Palm; Antero Aittomäki; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Secondary working fluids; secondary refrigerants; indirect systems; aqueous solutions; ice slurry; thermophysical properties; freezing point; density; viscosity; specific heat; thermal conductivity; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

    Sammanfattning : Secondary working fluids (secondary refrigerants, heat transfer fluids, antifreezes, brines) have long been used in various indirect re-frigeration and heat pump systems. Aqueous solutions (water solu-tions) have long been used as single phase (liquid only) secondary working fluids for cooling in supermarkets, ice rinks, heat recovery systems, heat pumps and other applications.
