1. 6. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
   Keywords : high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

   Abstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE

3. 7. A New FrontierThe emergence of the Outdoor Workspace

   University essay from KTH/Ergonomi

   Author : Robin Gülenay; [2023]
   Keywords : Utomhusarbetsplats; Utomhusarbetsmiljö; Naturbaserad arbetsplats; Arbetsplatsdesign; Hälsa och välbefinnande;

   Abstract : A new norm and culture has been created which has lowered the threshold for individuals to work from different and alternate locations, such as the outdoor workspace. The purpose of outdoor workspaces has been suggested to be designed to allow and provide individuals to work in a different scenery with the intention of providing mental and physical health effects that will improve wellbeing and productivity.

4. 8. Kvalitetsförändringar i ’Elise’- äpplen efter öppning av ULO-lager

   University essay from SLU/Dept. of Plant Breeding (from 130101)

   Author : Dag Pålsson; [2023]
   Keywords : Äpplen; lagring; shelf-life; kvalité; fasthet; sockerinnehåll; livsmedelsförluster;

   Abstract : För att kunna erbjuda konsumenter svenskproducerade äpplen över en stor del av året lagras frukten i sk ULO (ultra low oxygen) -lagring. Genom att temperatur, relativ fuktighet och atmosfär reglerass kan biologiska processer, såsom respiration och etylenproduktion, kontrolleras och sänkas vilket resulterar i att frukten håller längre och har bättre kvalité över en längre tid.

5. 9. Detectability of insects in Malaise traps : assessing insect detectability in Malaise traps through High-Resolution Sampling, and development of a novel marking technique

   University essay from SLU/Dept. of Ecology

   Author : Viktor Gårdman; [2023]
   Keywords : Malaise trap; activity; movement; weather; mark-recapture; detectability; insects;

   Abstract : Malaise traps are extensively used in insect surveys and studies, yet the detectability of insects in relation to the traps remain unknown. Detectability is the odds that a taxon ends up in a trap, given that the taxon is present in the area around the trap. READ MORE

6. 10. Heat recovery from low emission steel production through electrolysis and hydrogen reduction

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Sofia Kongshöj; [2023]
   Keywords : Electrolysis; H2 Green Steel H2GS ; waste heat recovery; district heating.; Earth and Environmental Sciences;

   Abstract : The steel industry is a large emitter of carbon dioxide and uses a lot of energy. Because of an increased awareness of the detrimental effects of climate change, research in alternative ways to operate steel plants have been made. It is now possible to build plants with far less emissions by using electrolysis and hydrogen reduction. READ MORE
