1. 26. Gravity water waves over constant vorticity flows: from laminar flows to touching waves

   University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

   Author : Francisco Gonçalves Jorge Dias de Carvalho; [2023]
   Keywords : Partial differential equations; Water waves; Euler equations; Free boundary problem; Bifurcation theory; Nonlinear functional analysis; Hilbert transform; Mathematics and Statistics;

   Abstract : In a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touching wave for fixed non-zero gravity. READ MORE

3. 27. Att motverka luftemboli vid transfusion av blodprodukter : en pilotstudie av produkten AirVault

   University essay from SLU/Dept. of Clinical Sciences

   Author : Amanda Nordgren; Marie-Louise Sund; [2023]
   Keywords : AirVault; blodtransfusion; FFP; hund; luftbildning; luftemboli; pRBC;

   Abstract : En blodtransfusion kan vara en livsnödvändig behandling vid akut blodförlust, anemi och vid vissa blödarsjukdomar. Att ge blodtransfusioner är dock inte helt riskfritt, en potentiell fara är att det kan bildas luftbubblor i blodet inom aggregatslangarna enligt Henrys lag. READ MORE

4. 28. Future-competing battery chemistries for large-scale energy storage

   University essay from KTH/Kemiteknik

   Author : Erik Adolfsson; [2023]
   Keywords : Battery energy storage systems; Nickel-hydrogen battery; Zinc-bromide flow battery; Iron-air battery; Large-scale applications; Batterier för energilagringssystem; Nickel-vätgasbatteri; Zink-brom flödesbatteri; Järn-luftbatteri; Storskaliga användningsområden;

   Abstract : ’Netto-noll utsläpp’ i EU vid 2050 är ett av målen för att påskynda övergången från fossila bränslen till mer förnyelsebara och hållbara alternativ. Detta har däremot introducerat mer turbulens på elnäten. READ MORE

5. 29. Mitigating Post-Harvest Losses in Bhutan through Solar Food Drying: Optimization and Analysis

   University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Author : Christian Rissler; [2023]
   Keywords : Solar dryer; Ginger; Drying; Bhutan; Heat exchanger; Heat storage; Solar absorber; Drying rate; Air flow; Technology and Engineering;

   Abstract : Bhutan is the world’s most mountainous country which comes with some logistical difficulties. Due to slow transportation times and lackluster food preservation are the post-harvest losses high which especially affects the rural parts of Bhutan negatively. READ MORE

6. 30. Modification of combined cycle power plant to reduce CO2 footprint

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : I Wayan Sudiasa; [2023]
   Keywords : Combined cycle; LNG; carbon capture; hydrogen blending.; Kombinerad cykel; LNG; kolavskiljning; väteblandning.;

   Abstract : Worldwide concern on reducing global warming consequences has motivated the development of power generation technologies to move towards renewable and sustainable energy. The process takes time and currently, a significant percentage of the world’s electricity systems are driven by fossil fuels. READ MORE
