  2. 1. Resistance of polygonal cross-sections : application on steel towers for wind turbines

    Author : Olga Garzon; Carlos Alberto da Silva Rebelo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : Wind power is considered an efficient alternative for production of electrical energy. One advantage that wind power offers compared to conventional ways of producing energy such as fossil energy and nuclear energy is the low emission of carbon dioxide “CO2” during production of electrical energy.

  5. 3. Fragmentation cross sections: measurement, systematics and model developement

    Author : Chiara La Tessa; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; projectile total charge-changing cross sections; weak factorization; strong factorization; projectile partial charge-changing cross sections; heavy-ions; space radioprotection; nuclear fragmentation;

    Abstract : Man's attitude towards space exploration has been mainly limited by the health risk related to the exposure to the space radiation environment. Some components of the space field can be characterized by such a high flux to kill a man if directly exposed and in general, all space radiation constitutes a hazard for astronauts engaged in long-term missions.

  6. 4. From Particle-Production Cross Sections to KERMA and Absorbed Dose for the Case 96 MeV n-12C Interactions

    Author : Bel E. Bergenwall; Ayşe Ataç; Eva Lund; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Fast neutrons; En = 96 MeV; charged-particle production; 12C n; px ; 12C n; dx ; 12C n; tx ; 12C n; 3Hex ; 12C n; ax reactions; cross sections; KERMA; microscopic measurements; absorbed dose; Kärnfysik; Nuclear physics; Kärnfysik;

    Abstract : Neutron-carbon interactions have been studied with a focus on charged-particle production of relevance to radiation protection and medical applications, such as cancer therapy. The measurements have been performed using the particle-detection setup, MEDLEY, and the 96 MeV neutron beam at the The Svedberg Laboratory in Uppsala. READ MORE

  7. 5. Investigations of Reaction Cross Sections for Protons and 3He

    Author : Mattias Lantz; Anders Ingemarsson; Livius Trache; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; reaction cross section; protons; 3He; experimental method; transmission method; optical model; parametrization; matter distributions; Kärnfysik; Nuclear physics; Kärnfysik;

    Abstract : The reaction cross section gives the probability that a particle will undergo a nonelastic process when passing through a nuclear medium. Therefore reaction cross section data are of importance both for theoretical studies and for applications in such diverse fields as medicine, biology, astrophysics and accelerator-driven transmutation of nuclear waste.
