  1. 6. Effects of cold and hand-arm vibration on the peripheral neurosensory and vascular system : an occupational perspective

    Författare :Daniel Carlsson; Jens Wahlström; Tohr Nilsson; Erik Nordh; Hans Pettersson; Tiina Ikäheimo; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hand-arm vibration; Raynaud’s phenomenon; paresthesia; sensation of cold; hand-arm vibration syndrome; quantitative sensory testing; cold sensitivity; cold; cold exposure; frostbite; Sweden; cold injury; military; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Background In Swedish working life, exposure to cold and exposure to hand-arm vibration (HAV) are two common health hazards. Health effects of HAV in the neurosensory, vascular and musculoskeletal systems are collectively denoted hand-arm vibration syndrome (HAVS), and have been thoroughly studied. LÄS MER

  3. 7. Public Health Programmes, Healthcare and Child Health

    Författare :Daniel Knutsson; Per Pettersson-Lidbom; Mårten Palme; Sonia Bhalotra; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public Health; Mortality; Infant Mortality; Piped Water; Well-visits; Crowding; Delivery Care; Sulfa; Information; Clean Water; Neonatal Mortality; Economics; nationalekonomi;

    Sammanfattning : This thesis consists of three self-contained chapters.Modern Medicine, Public Policy and Infant Health: Evidence from a Preventive Health Programme in Sweden. This paper explores a universal preventive health programme targeting infants that coincided in time with the introduction and availability of an early antibiotic, sulfa. LÄS MER

  4. 8. Strong n-generators in some one-dimensional domains

    Författare :Kerstin Pettersson; Daniel D Anderson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Sammanfattning : Let R be a commutative Noetherian one-dimensional domain such that each ideal in R can be generated by n elements. A strong n-generator in R is an element r which can be chosen as one of n generators for each ideal in which it is contained. LÄS MER

  5. 9. Multiple Kernel Imputation : A Locally Balanced Real Donor Method

    Författare :Nicklas Pettersson; Daniel Thorburn; Susanne Rässler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bayesian Bootstrap; Boundary Effects; External Information; Kernel estimation features; Local Balancing; Pólya Sampling; statistik; Statistics;

    Sammanfattning : We present an algorithm for imputation of incomplete datasets based on Bayesian exchangeability through Pólya sampling. Each (donee) unit with a missing value is imputed multiple times by observed (real) values on units from a donor pool. The donor pools are constructed using auxiliary variables. LÄS MER

  7. 10. Molecular structure and dynamics of liquid water : Simulations complementing experiments

    Författare :Daniel Schlesinger; Lars G. M. Pettersson; Paola Gallo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; liquid water; supercooled water; molecular simulation; evaporative cooling; teoretisk fysik; Theoretical Physics;

    Sammanfattning : Water is abundant on earth and in the atmosphere and the most crucial liquid for life as we know it. It has been subject to rather intense research since more than a century and still holds secrets about its molecular structure and dynamics, particularly in the supercooled state, i. e. the metastable liquid below its melting point.
