  1. 16. Swedish Numerals in an International Perspective

    Författare :Magnus Olsson; tolkning i offentlig sektor och översättning danska och isländska Avdelningen för svenska; []
    Nyckelord :HUMANIORA; HUMANITIES; synchrony; round numbers; base; vacillation; parallelism; affinity; inflection; derivation; dualism; affix; language change; language planning; dates; number; measurement; typology; homonymy; semantics; syntax; phonology; morphology; designation transition; Scandinavian languages and literature; Nordiska språk språk och litteratur ;

    Sammanfattning : Swedish numerals are here treated from different points of view. The book is however not intended to be a textbook of Swedish numerals, though one may learn a great deal about the system herein - more than the general user of the language knows. Phonology, morphology, syntax and semantics all get their fair share of attention. LÄS MER

  4. 18. Molecular mechanism of plasmid copy number control in Yersinia

    Författare :Tifaine Héchard; Helen Wang; Javier Pizarro-Cerda; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia pseudotuberculosis; plasmid copy number; T3SS; infection; ddPCR; Mikrobiologi; Microbiology;

    Sammanfattning : The ability of pathogenic bacteria to cause disease depends on various virulence mechanisms. The three pathogenic species of Yersinia use a type III secretion system (T3SS) to translocate effector proteins into host cells and disrupt the immune system. This T3SS is encoded on a 70kb, low-copy, virulence plasmid. LÄS MER

  5. 19. High Octane Number Fuels in Advanced Combustion Modes for Sustainable Transportation

    Författare :Amir Bin Aziz; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Octane number; Low temperature combustion LTC ; Ignition delay; Methanol; HCCI; PPC; Multiple injection strategy; φ-stratification;

    Sammanfattning : The research community recently proposed a low-temperature combustion (LTC) concept that can simultaneously reduce Nitrogen Oxides (NOx) and soot emissions while maintaining high engine efficiency. Given that diesel fuel is prone to preignition with early injection, gasoline-like fuel with high octane number is utilised to provide sufficient ignition delay and extend the load range. LÄS MER

  7. 20. Experimental Determination of Aeracoustic Sources in Low Mach Number Internal Flows

    Författare :Andreas Holmberg; Hans Bodén; Lars Enghardt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aeracoustics; ducts; N-ports; scattering matrix; wave decomposition; source determination; over-determination; flow noise; fluid-acoustic interaction; fluid-structure-acoustic interaction; wave number; T-junction; power balance; grazing-bias flow; Acoustics; Akustik; Vehicle engineering; Farkostteknik;

    Sammanfattning : In this thesis, the in-duct experimental methods for determining aeroacoustic N-ports of in-duct elements are discussed and improved. The scattering matrix determination methods and the related wave decomposition methods are evaluated from measurements in an empty duct carrying a mean flow. LÄS MER
