  1. 41. The Swampland and Early Universe Cosmology

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Alexia Nix; [2022]
    Keywords : Swampland; Early Universe; String Theory; Cosmology; Effective Field Theory; Dark Energy.;

    Abstract : Until now the quantum field theory (QFT) that successfully describes the electric, weak and strong interactions (three out of the four fundamental forces) between particles is the Standard Model, but it omits gravity. The prime candidate for a quantum theory of gravity is string theory. READ MORE

  3. 42. Pushing the boundaries of acoustic particle separation: achieving high-throughput, avoiding spillover effects, investigating the effects of the particle concentration, and measuring acoustic properties

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Linda Péroux; [2022]
    Keywords : Technology and Engineering;

    Abstract : Acoustophoresis, i.e., the contactless manipulation of small cells or particles via acoustic waves is a gentle and label-free method that can, amongst others, be used to isolate rare cells such as circulating tumor cells from blood. To isolate enough cells, a large amount of sample needs to be processed in a reasonable amount of time. READ MORE

  4. 43. Reduktion av viltskador i tallungskog med Trico

    University essay from SLU/School for Forest Management

    Author : Elis Gruvborg; Petter Ericsson; [2022]
    Keywords : tall; beteskador; viltskydd;

    Abstract : Ett stort problem för det svenska skogsbruket är viltskador på ung tall orsakad av klövvilt. De ekonomiska förlusterna av betningen är stora och i denna studie utvärderas en metod med Trico viltreppelent för att minska skador orsakade av vilt. READ MORE

  5. 44. Numerical simulations of pore pressure on concrete buttress dams

    University essay from KTH/Betongbyggnad

    Author : Mohammed Abdi; Dimitirios Ntzimanis; [2022]
    Keywords : Porepressureanalysis; upliftpressure; buttressdams; drainage; groutcur- tain; rockfractures; damsafety; RIDAS.;

    Abstract : Uplift pressure is one of the most dominant forces on a dam structure. Difference in head water and tail water creates a hydraulic gradient resulting an upward oriented pressure called uplift pressure, which reduces the dam safety against sliding. READ MORE

  6. 45. Studies of Dark Showers for Present and Future Colliders

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Nicoline Krogh Hemme; [2022]
    Keywords : high-energy particle physics; dark matter; collider physics; beyond the standard model; Physics and Astronomy;

    Abstract : In this work we explore a strongly-interacting dark sector with a Z’ portal to the Standard Model. We focus on the dark shower phenomenology and their semi-visible jet signatures with a strong emphasis on first principles of the theory. READ MORE
