  1. 1. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products

    University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Author : Fritjof Nilsson; Yanjun Peng; [2023]
    Keywords : Leak rate; Optimization; Pressure Decay; Vacuum Technology; Volume; Läckhastighet; Optimering; Tryckfall; Vakuum Teknologi; Volym;

    Abstract : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. READ MORE

  3. 2. Methanobacterium cauma sp. nov., a hydrogenotrophic, halotolerant methanogen from an active serpintinization system at Chimaera seep

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Aubree Stephens; [2023]
    Keywords : methanogen; archaea; hydrogenotroph; halotolerant; Methanobacterium; Chimaera seep; methanogenesis;

    Abstract : The archaeal branch of life represents some of the oldest life forms on Earth. Archaea are believed to have diverged from Prokaryotes roughly 3.5 billion years ago and it’s theorized that biological methane production started around this time as well. This would make methanogenesis one of the oldest metabolisms on our planet. READ MORE

  4. 3. Macroeconomic Factors and their role in Moderating Diversification effect of Asset Classes in the EU

    University essay from Umeå universitet/Företagsekonomi

    Author : Karl Nilsson; Tanyue Zheng; [2023]
    Keywords : macroeconomic factors; asset classes; diversification strategies; portfolio management; institutional qualities;

    Abstract : After the 2008 financial crisis, some have questioned the historically positive benefits ofdiversification, meanwhile others have stated a clear misunderstanding of whatdiversification entails. This study argues diversification is still viable in portfolio theory,and that more effort should be emphasized on macroeconomic factors’ role in theoptimal portfolio. READ MORE

  5. 4. OPTIMIZING CYCLE TIME OF ELECTRIC AUTONOMOUS HAULERS:A CASE STUDY IN MINING APPLICATIONS

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik; Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Victor Aziz; Hanna Brouillette; [2023]
    Keywords : ;

    Abstract : Traditionally, the fastest method to travel between two points is perceived as driving at maximumspeed. However, when the vehicle in question is an electric vehicle, the additional time requiredfor charging introduces another variable that can be optimized alongside driving time. READ MORE

  6. 5. Servicing or Buying New? Estimating the Environmentally Optimal Time for Car Replacement in Sweden – an LCA Approach.

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Larissa Patricia Wissert; [2022]
    Keywords : Sustainable Development; Life Cycle Analysis LCA ; Vehicle Replacement; ICEV; BEV; GHG Emissions;

    Abstract : Purpose. Road transportation is one of the major sources of GHG emissions today. Technological improvements in fuel consumption, as well as the electrification of vehicles can reduce emissions from road transportation. This study aims to investigate the optimal time for vehicle replacement in Sweden for an ICEV to minimise GHG emissions. READ MORE
