  2. 1. Dating Divergence Times in Phylogenies

    Author : Cajsa Lisa Anderson; Kåre Bremer; Katleen M. Pryer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; systematic biology; divergence time; nonprametric rate smoothing; Bayesian; multidivtime; eudicots; Neoaves; monocots; dating; molecular clock; relaxed clock; age constraint; fossil; calibration; PATHd8; penalized likelihood; Biology; Biologi;

    Abstract : This thesis concerns different aspects of dating divergence times in phylogenetic trees, using molecular data and multiple fossil age constraints.Datings of phylogenetically basal eudicots, monocots and modern birds (Neoaves) are presented. Large phylograms and multiple fossil constraints were used in all these studies. READ MORE

  4. 2. Avian thermoregulation across age and seasons

    Author : Fredrik Andreasson; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ambient temperature; body temperature; Cyanistes caeruleus; energy expenditure; hypothermia; life-history theory; metabolic rate; Parus major; thermoregulation; trade-off; winter ecology;

    Abstract : Animals constantly need to relate to prevailing environmental conditions and regulate their body temperature accordingly. Body temperature regulation in birds and mammals is inherently linked to energy expenditure and, thus, thermoregulation is a physiological mechanism that could trade-off with other costly processes, with potential long-term fitness consequences.

  5. 3. Lower-extremity constraint-induced movement therapy in individuals with stroke : improvements, experiences, and health-related quality of life

    Author : Ingela Marklund; Xiao-Lei Hu; Britt-Marie Stålnacke; Maria Klässbo; Brynjar Fure; Christina Brogårdh; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stroke; rehabilitation; high-intensity; lower-extremity; constraint-induced movement therapy; physiotherapy; experiences; qualitative content analysis; health-related quality of life; rehabiliteringsmedicin; Rehabilitation Medicine;

    Abstract : Background: Stroke is the third-leading cause of disability worldwide, and there are rehabilitation needs not only in the first year but throughout the lifetime. The ability to walk is crucial in everyday life since it affects mobility, self-care, and social activities. READ MORE

  6. 4. Durability Aspects of Fast Charging, Mechanical Constraint, and Inhomogeneity in Lithium-Ion Batteries

    Author : Abdilbari Shifa Mussa; Rakel Wreland Lindström; Göran Lindbergh; Gregory Offer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion batteries; NMC 111 ; Graphite; Cycle ageing; Fast-charging; Inhomogeneity; Current distribution; Pressure; Curvature; Temperature.; Chemical Engineering; Kemiteknik;

    Abstract : The development of lithium-ion batteries with higher energy and power density, better safety, and lower cost has significantly contributed to the increased market share of electric vehicles (EVs) in the last decade. However, the expectations of end-users of EVs still require a continuous quest for better performance. READ MORE

  7. 5. Intimate partner violence among women of reproductive age in Nigeria : magnitude, nature and consequences for reproductive health

    Author : Leah Okenwa; Karolinska Institutet; Karolinska Institutet; Stockholm Karolinska institutet Institutionen för folkhälsovetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Background: Intimate Partner Violence (IPV) against women is now recognised as a problem of global magnitude, owing to its detrimental consequences on the health, social and economic welfare of women and their children. This scenario has prompted increased research to understand its risk factors and data has indicated contextual variation in this regard, warranting an assessment in each unique setting. READ MORE
