2. 1. Infrared Laser-Induced Grating Techniques for Diagnostics in Reactive Flows

   Author : Dina Hot; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser diagnostics; infrared; laser-induced grating spectroscopy; degenerate four-wave mixing; flames; temperature; concentration; Fysicumarkivet A:2020:Hot;

   Abstract : AbstractThe work presented in this thesis is mainly focused on the development andapplication of infrared laser-induced grating techniques in order to measure the gasphase temperature and species concentrations in reactive flows. The two techniquesused for this purpose are laser-induced grating spectroscopy (LIGS) and degeneratefour-wave mixing (DFWM). READ MORE

4. 2. Too Hot! : an Epidemiological Investigation of Weather-Related Mortality in Rural India

   Author : Vijendra Ingole; Barbara Schumann; Joacim Rocklöv; Rainer Sauerborn; Sanjay Juvekar; Patrick Kinney; Umeå universitet; []
   Keywords : Temperature; heat and cold; mortality; education; socioeconomic status; occupation; rural population; India; folkhälsa; Public health;

   Abstract : BackgroundMost environmental epidemiological studies are conducted in high income settings. The association between ambient temperature and mortality has been studied worldwide, especially in developed countries. READ MORE

5. 3. Molecular aspects of WNT/Frizzled signalling in brain angiogenesis

   Author : Belma Hot; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The family of WNT lipoglycoproteins consists of 19 secreted proteins that are important for multiple cellular processes including cell proliferation, migration and fate. WNTs induce signalling cascades by binding the seven transmembrane receptors named Frizzleds (FZDs) classified as G protein-coupled receptors (GPCRs). READ MORE

6. 4. Hot forming tribology : galling of tools and associated problems

   Author : Leonardo Pelcastre; Ewald Badisch; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements; Centrumbildning - Centrum för högpresterande stål CHS ; Centre - Centre for High Performance Steel CHS ;

   Abstract : In recent years, the use of ultra high-strength steels (UHSS) as structural reinforcements and in energy-absorbing systems in automobiles has increased rapidly; mainly in view of their favourable strength to weight ratios. However, due to their high strength, the formability of UHSS is poor, thus complex-shaped UHSS components are invariably produced through hot-metal forming processes. READ MORE

7. 5. Graphene Hot-electron Transistors

   Author : Sam Vaziri; Mikael Östling; Max Lemme; Suman Datta; KTH; []
   Keywords : Graphene; hot-electron transistors; graphene base transistors; GBT; cross-plane carrier transport; tunneling; ballistic transport; heterojunction transistors; graphene integration; graphene transfer; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Graphene base transistors (GBTs) have been, recently, proposed to overcome the intrinsic limitations of the graphene field effect transistors (GFETs) and exploit the graphene unique properties in high frequency (HF) applications. These devices utilize single layer graphene as the base material in the vertical hot-electron transistors. READ MORE
