  2. 1. Measurements of 2π0 and 3π0 Production in Proton-Proton Collisions at a Center of Mass Energy of 2.465 GeV

    Author : Inken Koch; Sven Kullander; Alfons Khoukaz; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; two pion; three pion; production; WASA; Celsius; cross section; calorimeter; CsI crystals; kinematical distribution; Strålningsvetenskap; Radiation biology; Strålningsbiologi;

    Abstract : Neutral two- and three-pion productions in proton-proton collisions at a center of mass energy of 2.465 GeV have been studied using the WASA detector and an internal pellet target at the CELSIUS storage ring in Uppsala. READ MORE

  4. 2. Double Pion Production in the dd to αππ reaction

    Author : Samson Keleta; Pia Thörngren Engblom; Bo Höistad; Hans Ströher; Uppsala universitet; []
    Keywords : Nuclear physics; ABC effect; double pion; Kärnfysik; Nuclear Physics; kärnfysik;

    Abstract : The reaction dd → 4Heππ has been measured exclusively for the first time. The measurements were performed at Td = 712 MeV and Td = 1029 MeV, with the WASA detector assembly at CELSIUS (Uppsala-Sweden). The aim was to investigate a long standing puzzle, the so called ABC effect. READ MORE

  5. 3. The nature of stars with a common origin: clues from metallicity, elemental abundances, and kinematics

    Author : Cheng Liu; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stars: abundances; Galaxy: evolution; Galaxy: solar neighbourhood; Galaxy: bulge; Galaxy: globular clusters;

    Abstract : Most of field stars originate from dissolved star clusters. If the gas cloud is well mixed the stars in the cluster are expected to be chemically homogenous. READ MORE

  6. 4. The OH/IR Star Population in the Galactic Center

    Author : Loránt Olivér Sjouwerman; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The OH/IR stars and M-type Mira variables, that form the topic of this thesis are in two important ways different from OH/IR stars found elsewhere in the Galaxy. Their location in the central few tens of parsecs of the Galactic center allows one to study the dynamics of the Galaxy on that scale, and to investigata a population of evolved stars with a high metal abundance.

  7. 5. Physiological and biomechanical aspects of rifle carriage during biathlon skiing

    Author : Malin Jonsson Kårström; Marko Laaksonen; Kerry McGawley; Guillaume Millet; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D-measurement; anaerobic energy contribution; crosscountry skiing; kinematics; lactate threshold; load carriage; oxygen uptake; performance; sex differences; sub-techniques; training;

    Abstract : Biathlon is an endurance-based winter sport that combines crosscountry (XC) skiing with rifle marksmanship. While skiing, biathletes carry the rifle (weighing ≥ 3.5 kg) on their backs. However, research regarding the effects of rifle carriage in biathlon is lacking. READ MORE
