  2. 2. Firefighters' physical work capacity

    University dissertation from Umeå : Umeå Universitet

    Author : Ann-Sofie Lindberg; Umeå universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical demands; performance; work capacity; aerobic fitness; anaerobic fitness; muscle strength; muscle endurance; balance; ergonomics; physical testing; SIMCA;

    Abstract : The overall aim of this thesis was to identify valid, simple, and inexpensive physical tests that can be used for evaluation of firefighters’ physical work capacity. Paper I included fulltime- and part-time firefighters (n = 193), aged 20-60 years. READ MORE

  3. 3. Haploid selection in animals Exploring the fitness consequences and underlying mechanisms

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ghazal Alavioon; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sperm; evolution; haploid selection; reproductive aging; fitness;

    Abstract : A consequence of sexual reproduction in eukaryotes is the evolution of a biphasic life cycle with alternating diploid and haploid gametic phases. While our focus in evolutionary biology is on selection during the diploid phase, we know relatively little about selection occurring during the haploid gametic stage. READ MORE

  4. 4. Aerobic fitness and healthy brain aging cognition, brain structure, and dopamine

    University dissertation from Umeå : Umeå Universitet

    Author : Lars Jonasson; Umeå universitet.; Umeå universitet.; Umeå universitet.; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aerobic exercise; VO2; working memory; executive function; freesurfer; striatum; dopamine; D2-receptors; [11C]raclopride;

    Abstract : Background: Performing aerobic exercise and maintaining high levels of aerobic fitness may have positive effects on both brain structure and function in older adults. Despite decades of research however, there is still a rather poor understanding of the neurocognitive mechanisms explaining the positive effects of aerobic exercise on cognition. READ MORE

  5. 5. Experimental Evolution and Fitness Effects of Mutations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Knöppel; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Experimental evolution; Fitness effects; mutations; S20; fis; ribosome; horizontal gene transfer; adaptation; synonymous mutations; Mikrobiologi; Microbiology;

    Abstract : Bacteria have small, streamlined genomes and evolve rapidly. Their large population sizes allow selection to be the main driver of evolution. With advances in sequencing technologies and precise methods for genetic engineering, many bacteria are excellent models for studying elementary questions in evolutionary biology. READ MORE
