  1. 11. Den moderna 1800-talsgården : dagens behov i kombination med 1800-talets charm

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Helen Strid Bozac; [2018]
    Keywords : 1800-tal; trädgård; stilideal; Ormanäs; Skåne; gestaltning;

    Abstract : Den moderna 1800-talsgården handlar om en lantgård belägen i Ormanäs, norr om Västra Ringsjön mitt i Skåne. Familjen som bor här vill få en tydlig 1800-talsprägel på sin gård samtidigt som de har behov av att skapa en struktur på utemiljön som fungerar med deras moderna livsstil. READ MORE

  3. 12. Binder Migration in Double Pressed Drill Bit Inserts

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Axel Bjerke; [2018]
    Keywords : Physics and Astronomy;

    Abstract : It is possible to produce functionally graded cemented carbides on a large scale by double pressing. Being able to predict the binder migration in WC-Co cemented carbides during the sintering is essential to the design of such cemented carbides. The cobalt content is one of the main factors determining the hardness gradient. READ MORE

  4. 13. Urbana mikroklimat : designstrategier för solstrålning, vind, luft- och ljudkvalité

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Evelina Bengtsson; [2018]
    Keywords : mikroklimat; microclimate; solstrålning; vind; ljud; luftkvalité; design; termisk komfort; SLU;

    Abstract : Landskapsarkitekter ställs varje dag inför den svåra frågan: hur ska vi skapa städer som är ekonomiskt, socialt och ekologiskt hållbara? De urbana mikroklimaten rör alla dessa aspekter. Genom val av material, placering av hårda landskapselement och vegetation påverkar landskapsarkitekten allt från temperatur till ljudkvalité.

  6. 15. In-situ Reduction by Incorporating H2 Filled Hollow Glass Microspheres in PM HIP Capsules

    University essay from KTH/Materialvetenskap

    Author : Emil Strand; [2018]
    Keywords : Hot isostatic pressing; hollow glass microspheres; powder metallurgy; oxide reduction; surface oxides; hydrogen;

    Abstract : For many metal components the presence of hard, non-metallic inclusions such as oxides lowers the impact toughness by acting as fracture initiation points and easing crack propagation. In components produced by powder metallurgy hot isostatic pressing (PM HIP), oxides often form a continuous network of small, spherical inclusions after consolidation at the prior particle boundaries (PPB).
