  1. 16. Development of osmo- and appetite regulation during transfer of smolt from freshwater to increasing salinities

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Jonna Hellesten; [2023-01-26]
    Keywords : ;

    Abstract : Atlantic salmon (Salmo salar) is common in Scandinavian aquaculture and must be transferred from freshwater to seawater to grow properly. Despite being assessed as ready smolts, meaning they have gone through the physiological changes to prepare for SW transfer, the transfer result in a mortality rate of around 13-19%, and significant appetite- and growth reductions.

  3. 17. Selected PFAS in the water treatment at the waste-to-energy plant in Umeå : Investigating concentration and composition of selected PFAS in different water treatment steps

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Amanda Carlund; [2023]
    Keywords : ;

    Abstract : The present study investigated the changes in concentration and composition of five selected PFAS substances in the water treatment at the waste-to-energy plant in Umeå. The five PFAS were PFHxA, PFHpA, PFOA, PFHxS and PFOS. As PFAS exists in a variety of consumer products, they will to some extent end up in waste incineration. READ MORE

  5. 19. 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
