  1. 1. Life Cycle Assessment of Food Sensors

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Weijie Yan; [2023]
    Nyckelord :;

    Sammanfattning : The global demand for food increased with the booming trend of population, while food waste is a severe issue to be solved. Xanthine is a chemical compound which will accumulate in meat after the death of the animal, and the concentration of it can be an indicator of meat freshness. LÄS MER

  3. 2. Optimizing Conditions of Coagulation for Removal of Natural Organic Matter (NOM) : Comparison of Removal Efficiency of NOM When Using Bench-Scale Inline Coagulation Over Ultrafiltration and Classical Jar Tests

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Hiwa Oveisy; [2023]
    Nyckelord :drinking water; in-line coagulation; inline coagulation; jar test; membrane filtration; NOM removal; treatment; ultrafiltration; behandling; dricksvatten; inlinekoagulering; krusprov; membranfiltrering; NOM-borttagning; onlinekoagulering; ultrafiltrering;

    Sammanfattning : Abstract The removal of Natural Organic Matter (NOM) from water supplies is crucial for the provision of clean, safe drinking water. Lab-scale experiments have been extensively utilized in water treatment facilities to optimize this process. The most used lab-scale method is known as jar test. LÄS MER

  4. 3. Fouling modelling in a UHT unit based on plant data.

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Thai Lam; [2023]
    Nyckelord :UHT; dairy; tubular heat exchanger; fouling development; fouling removal; food engineering; Technology and Engineering; Agriculture and Food Sciences;

    Sammanfattning : Heat treatment of dairy products is essential for food safety, one way to perform this is ultra-high temperature (UHT) processing. During the process, macronutrients and minerals form fouling deposits which impairs heat transfer. Eventually the fouling needs to be removed chemically by alkaline and acidic detergents. LÄS MER

  5. 4. Use of a multi-parameter sensor for oil degradation monitoring

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Nicolas Gasnier; [2022]
    Nyckelord :;

    Sammanfattning : The continuous monitoring in real time of the degradation of lubricants is of great interest for many different industries to optimize the use of lubricating oil in combustion engines. Traditional oil quality diagnostic methods can measure accurately the different levels of oil degradation, but they cannot be implemented on engines to perform continuous oil quality diagnostics.

  7. 5. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Nsioh Elvis Nkioh; [2022]
    Nyckelord :geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

    Sammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER
