  1. 1. Feathers by day, membranes by night - Aerodynamic performance in bird and bat flight

    University dissertation from Department of Biology, Lund University

    Author : Florian Muijres; Lunds universitet.; Lund University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; animal flight; aerodynamics; vortex wake; actuator disk; flight performance; span efficiency; bird; bat; wind tunnel; PIV; Pied Flycatcher; Glossophaga soricina; Leptonycteris yerbabuenae;

    Abstract : Popular Abstract in English Animal flight has always intrigued people, and different aspects of animal flight have therefore widely been studied by biologists, physicists and engineers. At least to me, the aspect concerning the aerodynamics of animal flight in particular is very interesting because of the complex temporal varying wake dynamics as a result of continually wing morphing in flapping flight.

  2. 2. Aerodynamic performance in bat flight

    University dissertation from Lund University, Faculty of Science, Department of Biology

    Author : Jonas Håkansson; Lunds universitet.; Lund University.; [2017-05]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Leptonycteris yerbabuenae; Plecotus auritus; Glossophaga soricina; PIV; aerodynamics; wing morphology; bats; wind tunnel; animal flight;

    Abstract : Den här avhandlingen handlar om aerodynamik hos fladdermöss. Det vill säga, hur fladdermöss skapar de krafter som låter dem flyga, hur de påverkar luften för att åstadkomma detta, och hur deras vingar rör sig när de gör det. READ MORE

  3. 3. Energy flow and metabolic efficiency attributed to brown adipose tissue

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Author : Gabriella von Essen; Stockholms universitet.; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brown adipose tissue; BAT; UCP1; diet-induced thermogenesis; DIT; obesity; high-fat diet; energy expenditure; fysiologi; Physiology;

    Abstract : The large capacity of brown adipose tissue (BAT) to expend energy as heat makes it an interesting potential player in weight regulation and other metabolic conditions. This is of particular interest as it has been recognized that adult humans possess BAT. READ MORE

  4. 4. Bone Morphogenetic Protein 4 regulates white, beige and brown adipose tissue

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Author : Jenny M Hoffmann; Göteborgs universitet.; Gothenburg University.; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obesity; BMP4; Browning; WAT; BAT; insulin sensitivity;

    Abstract : Obesity and its associated complications, including Type 2 diabetes, are increasing at an epidemic rate globally. Adipose tissue exerts different functions and is central in energy homeostasis, and it consists of white, beige or brown adipocytes. READ MORE

  5. 5. Four Essays on Technology, Productivity and Environment

    University dissertation from Göteborg

    Author : Jan Larsson; Göteborgs universitet.; Gothenburg University.; [2006]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; BAT; DEA; Dynamic factor demand; Efficiency; Emission; Environmental regulation; Multiproduct symmetric generalized McFadden cost function; Malmquist index; Mexico; NAFTA; Norwegian manufacturing; Productivity; Trade liberalisation;

    Abstract : The main subject of this thesis is the relationship between economic growth and environmental effects when the interaction between firms' behaviour and regulations are taken into account. In the first three papers I discuss different aspects of the relationship between regulations and environmental effects. READ MORE
