  2. 6. Enhanced District Heating Technology : Maintaining Future System Feasibility

    Author : Helge Averfalk; Sven Werner; Urban Persson; Mei Gong; Patrick Lauenburg; Kerstin Sernhed; Per-Olof Johansson Kallioniemi; Louise Ödlund; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : When heat demand and high temperature heat supply gradually decreases in the future, then it will effect district heating systems ability to compete on the heat market. A good way to mitigate less district heating feasibility is to operate systems with lower temperature levels and the most conceivable way to achieve lower temperature levels is to decrease return temperatures.

  4. 7. On Crack Dynamics in Brittle Heterogeneous Materials

    Author : Jenny Carlsson; Per Isaksson; Urban Wiklund; Cecilia Persson; Ralf Denzer; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering science with specialization in Applied Mechanics; Teknisk fysik med inriktning mot tillämpad mekanik;

    Abstract : Natural variation, sub-structural features, heterogeneity and porosity make fracture modelling of wood and many other heterogeneous and cellular materials challenging. In this thesis, fracture in such complicated materials is simulated using phase field methods for fracture. READ MORE

  5. 8. Angiotensin-converting enzyme in cardiovascular function and dysfunction

    Author : Liza Ljungberg; Toste Länne; Karin Persson; Urban Alehagen; Thomas Kahan; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Angiotensin-converting enzyme (ACE) is a key enzyme in the renin-angiotensin system, converting angiotensin I to the vasoactive peptide angiotensin II, and degrading bradykinin. Angiotensin II is a multifunctional peptide, acting on a number of different tissues. READ MORE

  6. 9. Urban greenness and related health effects

    Author : Åsa Persson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Exposure to urban greenness has been linked to a wide range of health outcomes, including many non-communicable health conditions which are presently among the largest contributors to the global burden of disease, such as cardiovascular and metabolic diseases, as well as mental disorders. Half of the world’s population now lives in urban areas; often affected by health hazards such as pollutants and heat islands, and characterized by low levels of physical activity, inadequate diets, and decreased access to nature.

  7. 10. Intra-Representational Practice : An Inquiry into the Conditions for the Possibility of Interdisciplinary Imaginative Collaborative Architectural Modeling in Sustainable Urban Design

    Author : Pehr-Mikael Sällström; Daniel Koch; Helene Frichot; Gunilla Almström Persson; Isabelle Doucet; KTH; []
    Keywords : HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Practice epistemology; Architecture; Urban design; Collaborative modeling; Interdisciplinary imagination; Communicative interaction; Representation; Distributed cognition; Intermodal communication; Trans-discourse.; Praktisk kunskap; Arkitektur; Stadsbyggnad; Kollaborativ modellering; Interdisciplinär föreställning; Kommunikativ interaktion; Representation; Distribuerad kognition; Intermodal kommunikation; Trans-diskurs; Arkitektonisk gestaltning; Architectural Design;

    Abstract : A consequence of the concern for a sustainable future is that the number of experts needed to be included in the imaginative stage of architectural modeling is rising. This motivates a better understanding of the conditions for the possibility of transgressive collaborative plural imagination in architectural modeling. READ MORE
