1. 6. Seasonal Variability of Ice Nucleating Particles (INP) in Southern Sweden

   Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Författare :Tamina Kabir; [2023-03-08]
   Nyckelord :;

   Sammanfattning : Cloud ice crystals are formed by ice-nucleating particles (INPs). The micro-physical properties of clouds, precipitation formation and the life cycle of clouds are strongly influenced by the presence or absence of ice. Therefore knowledge of atmospheric INP concentrations is crucial to improve weather forecasting and climate projections. LÄS MER

3. 7. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Ahsan Ali; [2023]
   Nyckelord :High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

   Sammanfattning : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

4. 8. Wastewater Characterisation for Design and Modelling of Primary Settlers at Municipal Wastewater Treatment Plants

   Master-uppsats, Lunds universitet/Industriell elektroteknik och automation

   Författare :Louise Westin; [2023]
   Nyckelord :Primary Settling Tank; Wastewater Treatment; Settleometer; Particle Settling Velocity Distribution; Modelling.; Technology and Engineering;

   Sammanfattning : The primary settling tank (PST) is often one of the first treatment steps at a wastewater treatment plant (WWTP) and is the first process in the plant to remove significant amounts of suspended solids. Its role in wastewater treatment however, has oftentimes been neglected and little effort has been made to optimize and model the process. LÄS MER

5. 9. Exploring electroweak symmetry breaking in the scale-invariant Two-Higgs-Doublet Model

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Erik Rustas; [2023]
   Nyckelord :Two-Higgs-Doublet Models; 2HDM; Scale-invariance; Baryogenesis; BSM; Baryon Asymmetry; Coleman-Weinberg Potential; Theoretical Particle Physics; Physics and Astronomy;

   Sammanfattning : This thesis investigates the properties of a general scale-invariant Two-Higgs-Doublet Model and its phenomenological consequences with focus on the scalar sector. The concept suggests that introducing more CP-violation, both spontaneous and explicit, may make it possible to meet the Sakharov conditions and account for the Universe's baryon asymmetry. LÄS MER

7. 10. Brottsförebyggande urban design på bibliotek

   Kandidat-uppsats, KTH/Urbana och regionala studier

   Författare :Maria Hrnjez; [2023]
   Nyckelord :CPTED; Public library; Situational crime prevention; Criminals; Criminal acts; CPTED; Bibliotek; Situationell brottsprevention; Brottsutövare; Brottsliga handlingar;

   Sammanfattning : I denna rapport genomfördes en studie på fem folkbibliotek* i Stockholmsregionen, där bibliotekensomgivning och deras inre fysiska miljö undersöktes. Studien utfördes genom att besöka biblioteken där enbesiktning utfördes med hjälp av ett protokoll skapat utifrån teoretiska principer om situationellbrottsprevention och Crime Prevention through Environmental Design (CPTED).
