    Sammanfattning : Hjärt-kärl sjukdom är den vanligaste dödsorsaken i västvärlden. Samtidigt som antalet patienter med hjärtinfarkt har minskat, har antalet patienter med instabil kranskärlsjukdom d.v.s. LÄS MER

  3. 2. Variation in age and size at maturation in two benthic crustaceans in the Gulf of Bothnia

    Författare :Kjell Leonardsson; J. Ekman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Age at maturation; alternative prey; Bergmanris rule; cannibalism; growth; life-history theory; mortality; Mvoxocephalus quadricornis; poikilotherm; Pontoporeia affinis; population dynamics; risk- taking behaviour; Saduria entomon; size at maturation; temperature;

    Sammanfattning : The thesis deals with variation in age and size at maturation in Saduria entomon and Pontoporeia affinis along a depth gradient in the Gulf of Bothnia, Sweden. I have analysed at what sizes and ages animals should mature in relation to growth and mortality conditions. LÄS MER

  4. 3. Climate change impacts on production and dynamics of fish populations

    Författare :Per Hedström; Pär Byström; Jan Karlsson; Peter Eklöv; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Temperature; terrestrial dissolved organic carbon; light extinction; GPP; recruitment; winter mortality; metabolism; cohort competition; fish production; fish biomass;

    Sammanfattning : Ongoing climate change is predicted to increase water temperatures and export of terrestrial dissolved matter (TDOM) to aquatic ecosystems influencing ecosystem productivity, food web dynamics and production of top consumers. Ecosystem productivity is mainly determined by the rates of primary production (GPP) in turn controlled by nutrients, light availability and temperature, while temperature alone affect vital rates like consumption and metabolic rates and maintenance requirements of consumers.

  5. 4. Improved health economic assessments of sustainable transport solutions in urban environments

    Författare :Hedi Katre Kriit; Johan Nilsson Sommar; Joacim Rocklöv; Martin Andersson; Joel Schwartz; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; active commuting; electric vehicles; air pollution; particle matter; physical activity; morbidity; mortality; health economic evaluation; epidemiologi; Epidemiology; Public health; folkhälsa; sustainable development; hållbar utveckling;

    Sammanfattning : Introduction: Part of the European Strategy to achieve climate neutrality in the transport sector is to increase the proportion of electric vehicles (EVs) and active commuting. Health co-benefits from reduced air pollution and increased active commuting are assumed to follow; however, all dimensions of expected health effects are not quantified nor valued monetarily.

  7. 5. Boning up on Vitamin D : Observational Studies on Bone and Health

    Författare :Greta Snellman; Karl Michaëlsson; Haakon Meyer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vitamin D; fracture; BMD; assays; genes; mortality; cohort studies; Orthopaedics; Ortopedi;

    Sammanfattning : The primary function of vitamin D in humans is to maintain sufficient circulating calcium concentrations. Low vitamin D levels could result in excessive calcium resorption from bone. Vitamin deficiency may therefore decrease bone mineral density (BMD), resulting in an increased risk of fracture. LÄS MER
