  1. 1. Development of New Monte Carlo Methods in Reactor Physics : Criticality, Non-Linear Steady-State and Burnup Problems

    Author : Jan Dufek; Jan Wallenius; Waclaw Gudowski; Cheikh Diop; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; reactor physics; fission source; inactive cycles; convergence; burnup; steady-state; criticality; eigenvalue; Nuclear physics; Kärnfysik;

    Abstract : The Monte Carlo method is, practically, the only approach capable of giving detail insight into complex neutron transport problems. In reactor physics, the method has been used mainly for determining the keff in criticality calculations. READ MORE

  2. 2. Development and Evaluation of Validity and Utility of the Instrument Assessment of Work Performance (AWP)

    Author : Jan Sandqvist; Björn Gerdle; Jan Ekholm; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ability; measurement; MOHO; occupational therapy; rehabilitation; vocational; Occupational therapy; Arbetsterapi;

    Abstract : The last decades have shown a great need for vocational rehabilitation due to high levels of absenteeism due to sickness and disability pension. An essential part of the vocational rehabilitation process is assessment of persons with reduced work functioning. READ MORE

  3. 3. Reading bones : Stone Age hunters and seals in the Baltic

    Author : Jan Storå; Jan Ekman; Stockholms universitet; []
    Keywords : Epiphyseal fusion; Harp seal; Marine mammals; Neolithic; Pitted Ware culture; Ringed seal; Seal hunting; Seasonality; Taphonomy; arkeologi; Archaeology;

    Abstract : This is a study of hunters and seals in the Stone Age in the Baltic. The ambition has been to develop and utilize methods for osteological analyses of archaeological seal bones. The main aims of the zooarchaeological analyses have been to study seal hunting strategies and the formation processes of the faunal remains. READ MORE

  4. 4. Sleep Related Movement Disorders : Association with Menopause and Pregnancy

    Author : Jan Wesström; Inger Sundström-Poromaa; Jan Ulfberg; Staffan Nilsson; Päivi Polo; Uppsala universitet; []

    Abstract : It is known that sleep problems affect people’s wellbeing and has great consequences for public health.Restless legs syndrome (RLS) gives uncomfortable sensations in the legs at rest, leading to an irresistible need for activity. It aggravates in evening and at night. READ MORE

  5. 5. Interaction between Electromagnetic Waves and Localized Plasma Oscillations

    Author : Jan-Ove Hall; Thomas Leyser; Jan Trulsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; space physics; plasma physics; radio waves; ionospheric modification; density depleations; field-aligned irregularities; lower hybrid solitary structures; lower hybrid cavities; Z mode waves; magnetosonic waves; scattering; mode conversion; Rymd- och plasmafysik; Space physics; Rymdfysik;

    Abstract : This thesis treats interaction between electromagnetic waves and localized plasma oscillations. Two specific physical systems are considered, namely artificially excited magnetic field-aligned irregularities (striations) and naturally excited lower hybrid solitary structures (LHSS). READ MORE
