  2. 16. Describing Interstitials in Close-packed Lattices: First-principles Study

    Author : Noura Al-Zoubi; Levente Vitos; Se Kyun Kwon; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Describing interstitial atoms in intermetallics or simple mono-atomic close-packed metals is a straightforward procedure in common full-potential calculations. One establishes a sufficiently large supercell, introduces the interstitial impurity and performs the electronic structure and total energy calculation. READ MORE

  4. 17. The miswak (chewing stick) and oral health : studies on oral hygiene practices of urban Saudi Arabians

    Author : Meshari Al-Otaibi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Chewing stick; DNA probe; miswak; oral hygiene; oral microbiota; Salvadora persica; subgingival plaque; Saudi Arabia;

    Abstract : The miswak, a traditional chewing stick for cleaning teeth, is made from the plant Salvadora persica. For religious and cultural reasons, miswak use is firmly established and widespread in Saudi Arabia and most other Muslim countries. Only recently has scientific evaluation of the miswak been undertaken. READ MORE

  5. 18. Towards elimination of anal-sphincter and rectal dysfunction after radiation therapy for prostate cancer

    Author : Massoud al-Abany; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Fecal leakage; rectal bleeding; defecation urgency; diarrhea; dose; volume; and potency.;

    Abstract : Background: External radiation therapy is one of the best management options available for localized prostate cancer. The higher the radiation therapy dose administered, the more likely local control will be obtained, but the radiation dose that can be given is limited by the need to restrict the frequency and severity of unwanted effects.

  6. 19. Investigation of 234U(n,f) with a Frisch-grid ionization chamber

    Author : Ali Al-Adili; Franz-Josef Hambsch; Stephan Pomp; Richard Brenner; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : This work treats three topics. The main topic concerns neutron-induced fission of 234U. The main goal is to investigate the fission-fragments properties  as a function of the incident neutron energy. The study was carried out using a twin Frisch-grid ionization chamber. READ MORE

  7. 20. Measurements of the 234U(n,f) Reaction with a Frisch-Grid Ionization Chamber up to En=5 MeV

    Author : Ali Al-Adili; Pomp Stephan; Franz-Josef Hambsch; Michael Österlund; Talou Patrick; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fission; U-234; Neutron; Uranium; Resonance; Ionization Chamber; Frisch-grid; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Abstract : This study on the neutron-induced fission of 234U was carried out at the 7 MV Van de Graaff accelerator of IRMM in Belgium. A Twin Frisch-Grid Ionization Chamber (TFGIC) was used to study 234U(n,f) between En = 0.2 and 5.0 MeV. READ MORE
