  1. 6. Noise emissions from sustainable transport : A multi-scale modeling approach

    Författare :Johan Nygren; Susann Boij; Romain Rumpler; Ciarán J. O'Reilly; Eoin King; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic simulation; sustainable transport; environmental noise; vehicle acoustics; energy efficiency; Trafiksimulering; hållbar transport; samhällsbuller; fordonsakustik; energieffektivitet; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Noise emissions from transportation remain one of the greatest environmental issues of modern day. Inhabitants in urban environments are especially exposed, with almost 80 million people in the European Union exposed to noise levels exceeding the recommended limits set by the World Health Organization (WHO).

  3. 7. Hadronic Structure Measurements of the Photon by DELPHI at LEP II

    Författare :Andreas Nygren; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elementarpartikelfysik; DELPHI; LEP; VSAT; luminosity; two-photon physics; cross section; double tag; bhabha; background; structure function; kvantfältteori; quantum field theory; Elementary particle physics; Fysicumarkivet A:2001:Nygren;

    Sammanfattning : This thesis is mainly an analysis of data taken by the VSAT detector in the DELPHI experiment at the LEP II collider at CERN. The analysis spans from 1998 to 2000, with a center of mass energy ranging from 189 to 206 GeV. LÄS MER

  4. 8. Development of Multi-Dimensional Laser Techniques for In-situ Combustion Diagnostics

    Författare :Jenny Nygren; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser Diagnsotics; Visualisation; Laser technology; Laserteknik; Motors and propulsion systems; Motorer; framdrivningssystem; Combustion; Temperature; Fysicumarkivet A:2003:Nygren;

    Sammanfattning : Multi-dimensional, laser-based measurements of quantities important for obtaining a better understanding of combustion processes, particularly of temperature and of species distributions, were performed using laser-induced fluorescence (LIF). The main purpose of the temperature experiments was to investigate the potential of employing a two-line atomic fluorescence technique (TLAF), using indium as the tracer species, in sooting environments such as in diesel engines.

  5. 9. Nedläggningen av NCB i Köpmanholmen : en studie av de hushållsekonomiska konsekvenserna

    Författare :Lennart Nygren; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Plant close-cown; unemployment insurance; household economy of the unemployed; receiving supplementary benefits; adjustment strategies; strategies of social policy; labour market mobility;

    Sammanfattning : This study deals with the consequences for household economy in connection with unemployment. Various mechanisms that influence the relationship between unemployment and the reception of supplementary benefits are described and analyzed. LÄS MER

  7. 10. A mouse model for direct evaluation of cholera vaccines

    Författare :Erik Nygren; Göteborgs universitet; []
    Nyckelord :Vibrio cholerae; cholera vaccine; cholera toxin; LPS; anti-bacterial immunity; IgA; challenge; protection; colonization;

    Sammanfattning : Cholera continues to be an important cause of morbidity and mortality in large parts of the developing world and is a significant negative factor for economic development. Vibrio cholerae bacteria of the O1 or O139 serogroup can cause disease due to their ability to colonize the intestine and produce an enterotoxin, cholera toxin (CT). LÄS MER
