  2. 6. Probabilistic Modelling of Air Infiltration and Heat Loss in Low-Rise Buildings

    Author : Krystyna Pietrzyk; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation; heat loss; reliability; leakage; air infiltration; risk analysis; thermal transmittance; probabilistic model; wind; building physics;

    Abstract : A probabilistic model (PROMO) of air exchange and heat loss in a low-rise building with a lightweight construction is proposed. The probability distributions of the air change rate and of the heat loss are the main outputs of the model. READ MORE

  4. 7. The role of hematopoietic chromosome Y loss in health and disease

    Author : Jonas Mattisson; Lars A. Forsberg; Jonatan Halvardson; Adam Ameur; Andrea Ganna; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; loss of chromosome Y; LOY; mosaic loss of chromosome Y; mLOY;

    Abstract : Mosaic loss of chromosome Y (mLOY) is the most common somatic mutation, and affected men have increased risk for all major causes of death, including cardiovascular diseases and cancer. As a male specific mutation, it helps explain why men live shorter lives than women. READ MORE

  5. 8. Thermal Modeling of Walls, Foundations and Whole Buildings Using Dynamic Thermal Networks

    Author : Eva-Lotta Wentzel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; walls; weighting functions; Dynamic thermal networks; building; dynamic heat conduction; foundation; step-response functions;

    Abstract : The modeling of the energy balance of buildings is a major task in building physics. A new theory called dynamic thermal networks is under development at the Building Physics Research Group at Chalmers. The calculations are based on step-response functions, and the problems are illustrated in so-called dynamic networks. READ MORE

  6. 9. Evolution of New Genes and Functions

    Author : Erik Lundin; Dan I Andersson; Joakim Näsvall; Diarmaid Hughes; Arjan de Visser; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : To answer major evolutionary questions, we need a better understanding of the effects of mutations on specific functions and organism fitness. The aim of this thesis was to elucidate how new functions evolve and potential trade-offs with the original function. READ MORE

  7. 10. Functions of Pericytes in Ischemic Stroke

    Author : Michaela Roth; Lund Neurologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stroke; Pericytes; RGS5; Blood-brain barrier; vascular remodelling; scar formation;

    Abstract : Ischemic stroke remains one of the leading causes of death and disability worldwide, and its burden is predicted to further increase due to the aging population. The only available treatments, thrombolysis or thrombectomy, can only be applied within a limited time window after stroke onset, and thus are applicable only to a small proportion of stroke patients.
