  1. 36. Molecular population genetics of inducible defense genes in Populus tremula

    Författare :Carolina Bernhardsson; Stefan Jansson; Santiago González-Martinez; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Populus; herbivore defense; adaptation; population genetics; population structure; association mapping; complex traits; evolutionär genetik; evolutionary genetics;

    Sammanfattning : Plant-herbivore interactions are among the most common of ecological interactions. It is therefore not surprising that plants have evolved multiple mechanisms to defend themselves, using both constitutive chemical and physical barriers and by induced responses which are only expressed after herbivory has occurred.

  2. 37. Safe Intersection and Merging Coordination of Connected and Automated Vehicles

    Författare :Xiao Chen; Jonas Mårtensson; Björn Olofsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Connected and automated vehicles (CAVs) are a transformative technology that promises to bring innovative solutions to transportation systems. One of their significant advantages is the elimination of human factors, which makes them capable of resolving the congestion problem prevalent in areas such as ramp merging points and road intersections.

  3. 38. Exercise training and testing in patients with heart failure

    Författare :Charlotta Lans; Lars Brudin; Eva Nylander; Åsa Cider; Anita Wisén; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Patients with heart failure (HF) suffer from symptoms such as dyspnea, fatigue and reduced quality of life, which affect their physical function and often lead to immobilization and poor survival prognosis. Exercise training in cardiac rehabilitation should be offered to every patient with HF and can be performed both in a hospital-setting and with a home training programme. LÄS MER

  4. 39. Make It Easier : A psychological perspective on sustainable behavior change

    Författare :Noah Linder; Stephan Barthel; Therese Lindahl; Robert Ljung; Patrik Sörqvist; Janne Hukkinen; Högskolan i Gävle; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pro-environmental behavior; behavior change; intervention; habits; intentions; information; nudge; choice architecture; miljövänligt beteende; beteendeförändring; vanor; intentioner; information; nudge; valarkitektur; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : Human behavior is the cause of most environmental challenges we face today, and widespread behavioral change is urgently needed across actors and scales. Even though the public perception of the current ecological crisis has changed drastically in recent decades, a corresponding shift in behavior is lacking — unfortunately, mere belief in climate change is a poor predictor of taking action.

  5. 40. Traveller information in support of the mobility of older people and people with disabilities. User and provider perspectives

    Författare :Nina Waara; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Traveller information designed to fulfil needs and expectations of individual travellers is a key factor in improving access for older people and people with disabilities to public transport. The overall aim of this thesis is to contribute to the knowledge of user and provider perspectives on the provision of traveller information for older people and people with disabilities in public transport with a focus on use and provision of such traveller information through online traveller information services.
