  1. 1. Single Phase Convective Heat Transfer with Nanofluids : An Experimental Approach

    Författare :Ehsan Bitaraf Hgahighi; Björn E. Palm; Elena V. Timofeeva; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofluid; convective heat transfer; thermal conductivity; viscosity; heat transfer coefficient; performance; pumping power; Reynolds number; shelf stability;

    Sammanfattning : Nanofluids (NFs) are engineered colloids of nanoparticles (NPs) dispersed homogenously within base fluids (BFs). Due to the presence of NPs, the thermophysical and transport properties of BFs are subject to change. LÄS MER

  2. 2. Kognitiva och metakognitiva perspektiv på läsförståelse inom matematik

    Författare :Magnus Österholm; Björn Textorius; Christer Bergsten; Carl Winsløw; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematical texts; metacognition; reading comprehension; self-regulation; university; upper secondary level; beliefs; cognition; gymnasium; kognition; läsförståelse; matematiska texter; metakognition; självreglering; universitet; uppfattningar; Subject didactics; Ämnesdidaktik;

    Sammanfattning : Det verkar finnas en allmän uppfattning om att matematiska texter är så speciella att man måste få lära sig en särskild typ av läsförmåga för att förstå sådana texter. Denna uppfattning verkar dock inte vara baserad på forskningsresultat eftersom det visar sig inte finnas mycket forskning genomförd som behandlar läsförståelse inom matematik. LÄS MER

  3. 3. To include or not to include : Teachers’ social representations of inclusion of students with Asperger syndrome

    Författare :Ann-Charlotte Linton; Christina Chaib; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inclusion; Asperger diagnosis; mainstream teachers; social representations; Inkludering; Asperger diagnos; lärare; sociala representationer;

    Sammanfattning : Evidence on inclusive classrooms shows that successful implementation of inclusion can lead to increased social involvement, personal well-being and higher levels of academic performance compared with segregated provision. Despite these potential benefits inclusion of students with Asperger syndrome (AS) in the mainstream classroom is problematic. LÄS MER

  4. 4. Impact of erosion and deposition processes on wall materials in tokamaks

    Författare :Sunwoo Moon; Marek Rubel; Per Petersson; Wolff Max; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Understanding of material migration and control of fuel retention are essential for the safe operation of a reactor-class fusion machine. Work presented in the thesis focuses on erosion-deposition processes which are decisive for the formation and properties of co-deposited fuel-containing layers on plasma-facing and diagnostic components, and for the dust formation.

  5. 5. Ready meals from the consumers' perspective : attitudes, beliefs, contexts and appropriateness

    Författare :Mia Prim; Inga-Britt Gustafsson; Gunnar Hall; John Edwards; Örebro universitet; []
    Nyckelord :attitude; consumer; context; food choice; meal; ready meal; situation; attityd; färdigmat; konsument; kontext; matval; måltid; situation; Culinary Arts and Meal Science; Måltidskunskap; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Måltidskunskap; Culinary Arts and Meal Science;

    Sammanfattning : The aim of this thesis was to gain a deeper understanding of ready meal consumers and their demands regarding ready meal products in different situations. Data were gathered with one extensive postal survey and five focus group discussions. LÄS MER
