  1. 1. Optimization of concrete recipe made with crushed aggregate

    Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Jonathan Lindekrantz; Pontus Axelsson; [2023]
    Nyckelord :;

    Sammanfattning : This paper investigate however concrete recipes with a specific type ofcrushed aggregate can be optimized to reduce cement content for concreteand compares it to concrete made with natural fine aggregate. The different aggregate types are sieved, and the particle size distribution curve is made for each one. LÄS MER

    Sammanfattning : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. LÄS MER

  4. 3. Effekter av packning av finfilter i fyllningsdammar

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Anton Jonsson; [2023]
    Nyckelord :Fyllnadsdamm; Finfilter; Packningsgrad;

    Sammanfattning : There are over 10 000 dams in Sweden of various types and sizes. Most of the larger dams were built around 1950-1970 when the Swedish hydropower was expanded. Since then, the knowledge of engineering dam structures has increased and there are new guidelines for how a dam should be built. LÄS MER

  5. 4. Properties & Stability of Hybrid Pea-Dairy Protein Formulas

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Kyriaki-Eirini Moschou; [2023]
    Nyckelord :properties; stability; hybrid formula; pea-dairy; protein mixtures; development; RTD; Agriculture and Food Sciences;

    Sammanfattning : The aim of this study was to investigate the functional properties and stability of hybrid pea-dairy protein formulas. To achieve this goal, the combination of pea protein isolate (PPI) with dairy proteins such as micellar casein isolate (MCI), sodium caseinate (NaCas), whey protein aggregate (WPA) was evaluated.

  7. 5. Magnetic properties of a martensitic stainless steel powder : Investigation of magnetic properties for a metallic powder with different sizes and its possible correlation to flow properties

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Carl Back; Saga Grevarp; Arthur Pollet; [2023]
    Nyckelord :;

    Sammanfattning : For metal powders, flow properties are important. If the powder does not move properly, it can result in problems with the final product in additive manufacturing. Some of the products created with this manufacturing method are complex and used for important purposes such as medical devices and aerospace. LÄS MER
