  1. 1. Numerical and experimental investigation of multiple gas jet flow behaviour in the gas atomization process

    Master-uppsats, KTH/Materialvetenskap

    Författare :Mahsa Darvishghanbar; [2022]
    Nyckelord :;

    Sammanfattning : In several industrial applications, the interaction of supersonic gas jets is encountered such as gas atomization, jet engines and the basic oxygen furnace process. In the gas atomization process, high pressure gases are converted to high velocity gas jets through convergent-divergent nozzles. LÄS MER

  3. 2. Spatial patterns of Dissolved Organic Matter in Swedish Surface Waters

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Anna Lackner; [2022]
    Nyckelord :Dissolved Organic Matter; Brownification; Digital Mapping; Soil Moisture; Stream Length;

    Sammanfattning : Dissolved organic matter (DOM) in surface water has been widely studied, in part due to its significance for aquatic ecology and drinking water quality. Across Sweden, increases in the total organic carbon (TOC) concentrations and color of surface waters, known as brownification, were noted in the decades before and after year 2000, though recent analysis has found widespread DOM increase to have ceased after 2010.

  4. 3. The role of bed sediments for fractionation of phosphorus in remediated ditches in Sweden

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Emma Ryding; [2022]
    Nyckelord :Phosphorus fractionation; agricultural stream; sediment; two-stage ditch; eutrophication;

    Sammanfattning : Sweden’s environmental quality objectives “A varied agricultural landscape” and “Zero eutrophication”, aims to ensure food production while reducing negative impact from fertilizers on the environment. The input ceilings of nutrient concentrations in the Baltic Sea are still critical. LÄS MER

  5. 4. Investigating the dynamics controlling dissolved organic matter bioreactivity in agricultural stream water and its link to carbon evasion : A statistical analysis

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Sara Schützer; [2022]
    Nyckelord :;

    Sammanfattning : While streams and rivers emit large quantities of CO2 to the atmosphere, both the mechanisms controlling CO2 evasion as well as the sources of CO2 are still uncertain. One potential source of stream CO2 is in-stream degradation of dissolved organic matter (DOM). LÄS MER

  7. 5. Identifiering och minimering av slöserier på en liten tandläkarklinik

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för industriell ekonomi, industridesign och maskinteknik

    Författare :Mario Jergees; Ramtin Eftekhari; [2022]
    Nyckelord :Lean; Kaizen; 5S; värdeflödesanalys; visuell styrning; slöseri; små tandläkarkliniker;

    Sammanfattning : This case study focuses its purpose on the use of Lean tools for identification and minimization of waste on small dental clinics. During the projects course we will examine how Lean tools can be used to identify different types of waste dynamics. Then which wastes that are identified and how these can be minimized. LÄS MER
