  1. 11. Plasminogen : a pleiotropic inflammatory regulator in radiation-induced wound formation and wound repair

    Author : Mahsa Fallah; Tor Ny; Malgorzata Wilczynska; Robert Medcalf; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The plasminogen activator (PA) system plays important roles in many physiological and pathological processes, including inflammation and wound healing. Plasmin, the central component of the PA system, is a broad-spectrum serine protease that is derived from its inactive precursor form, plasminogen. READ MORE

  2. 12. Palaeoenvironment in North-Western Romania during the last 15 000 years

    Author : Angelica Feurdean; Barbara Wohlfarth; Ann-Marie Robertsson; Leif Björkman; Iustinian Petrescu; Katherine J Willis; Stockholms universitet; []
    Keywords : Northwest Romania; Gutaiului Mountains; pollenstratigraphy; macrofossil remains; Lateglacial; Holocene; tree refugia; tree dynamics; past climate; human influence;

    Abstract : The objectives of this thesis are to establish a chronological framework for environmental changes during the last 15,000 years in northwest Romania, to reconstruct the vegetation development, and to evaluate the underlying processes for forest dynamics. Furthermore, an overview of earlier and ongoing pollenstratigraphic work in Romania is provided. READ MORE

  3. 13. Fabry-Pérot based refractometry : development of a transportable refractometer for assessment of gas pressure

    Author : Clayton Forssén; Ove Axner; Isak Silander; Martin Zelan; Leslie Pendrill; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fabry-pérot; refractometry; optical resonator; transportable; pressure standard; gamor; pressure; metrology; ring comparison; si; pascal; quantumpascal; fysik; Physics;

    Abstract : A unified description of physical phenomena through measurement science is one of the foundational pillars in a global society. The International System of Units (SI) is the most widely used system of units and since its redefinition in 2019, all units encompassed by it are based on fundamental physical constants. READ MORE

  4. 14. Mechanisms of inelastic behavior of fiber reinforced polymer composites

    Author : Konstantinos Giannadakis; Lars-Olof Nordin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : In the present thesis, the sources of linear/non-linear viscoelastic and viscoplastic behaviour in polymer composite materials are under study. The significance of this work is related to the nature of all composite materials. All polymer composites tend to indicate a time-dependent behaviour. This behaviour can be either linear or nonlinear. READ MORE

  5. 15. Mechanisms controlling air-sea gas exchange in the Baltic Sea

    Author : Lucía Gutiérrez-Loza; Anna Rutgersson; Erik Sahlée; Marcus Wallin; John Prytherch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Air-sea gas exchange; Baltic Sea; CO2 flux; methane flux;

    Abstract : Carbon plays a major role in physical and biogeochemical processes in the atmosphere, the biosphere, and the ocean. CO2 and CH4 are two of the most common carbon-containing compounds in the atmosphere, also recognized as major greenhouse gases. READ MORE
