  2. 1. Adolescent self-reported health in the Umeå region : Associations with behavioral, parental and school factors

    Author : Karina Nygren; Lennart Nygren; Urban Janlert; Curt Hagquist; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; adolescence; school survey; self-reported health; somatic complaints; stress; norm compliance; parent-adolescent relations; compulsory school; school managers; research utilization; ungdomar; skolenkät; självrapporterad hälsa; somatiska besvär; stress; normföljsamhet; föräldrarelationer; skola; skolområdeschefer; forskningsanvändning;

    Abstract : This thesis consists of a quantitative and a qualitative study. The quantitative study (articles I-III) aimed to examine how self-reported health in adolescence is associated with behavioral, parental, and school factors. Through a survey directed at all adolescents in grades 7-9, data were collected in 2005 in a region in northern Sweden (n=5060). READ MORE

  4. 2. Hadronic Structure Measurements of the Photon by DELPHI at LEP II

    Author : Andreas Nygren; Partikel- och kärnfysik; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Development of Multi-Dimensional Laser Techniques for In-situ Combustion Diagnostics

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

    Abstract : 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.

  6. 4. Molecular diagnostics of infectious diseases

    Author : Malin Nygren; KTH; []
    Keywords : ;

    Abstract : In DNA-based diagnostics, the polymerase chain reaction(PCR) is the most widely used DNA amplification method. Toenable both sensitive and specific detection of agents causinginfectious diseases, the PCR needs to becombined with methodsto prepare the clinical sample containing the genetic materialof the pathogen.

  7. 5. Growth hormone and the heart in children

    Author : Anders Nygren; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone secretion pattern; Cardiac dimensions; Growth hormone treatment;

    Abstract : Background and Aims: The fact that growth hormone (GH) influences cardiovascular structure and function is well established through both human and animal studies. Despite being secreted in a pulsatile fashion, only the impact of peak GH concentrations on cardiac parameters has previously been reported, and the time-dependency of cardiovascular effects during GH treatment has not been detailed.
