    Författare :Maria Furberg; Maria Nilsson; Anders Johansson; Lars Weinehall; Peter Friberg; Umeå universitet; []
    Nyckelord :Climate change; public health; Indigenous peoples; Sami; reindeer herding; resilience; tularemia; mixed-methods; infectious disease; seroprevalence; ELISA; outbreak investigation; risk factor; ecology; Francisella tularensis; Epidemiology; epidemiologi; folkhälsa; Public health;

    Sammanfattning : BackgroundIndigenous peoples with traditional lifestyles worldwide are considered particularly vulnerable to climate change effects. Large climate change impacts on the spread of infectious vector-borne diseases are expected as a health outcome. LÄS MER

  3. 17. Polymer Actuators for Micro Robotic Applications

    Författare :Erik Edqvist; Stefan Johansson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micro actuator; PVDF-TrFE; I-SWARM; Multilayer actuator; Materials science; Teknisk materialvetenskap;

    Sammanfattning : In this thesis a multilayer actuator structure is developed for the I-SWARM project. In order to build an energy efficient and low voltage actuator system for the 3x3x3 mm3 robot, the resonance drive mode in combination with a ten layer multilayer structure build upon the most suitable substrate material was used.

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epidemiology; COPD; ischemic heart disease; cardiovascular disease; ECG; spirometry; kardiologi; Cardiology;

    Sammanfattning : Background: Chronic Obstructive Pulmonary disease (COPD) is an under-diagnosed disease with a prevalence of approximately 10%, highly dependent on age and smoking habits. Comorbidities are common in COPD and of these, cardiovascular diseases (CVD) are the most common. LÄS MER

  5. 19. Challenges of renovating the Gothenburg multi-family building stock - An analysis of comprehensive building-specific information, including energy performance, ownership and affordability

    Författare :Mikael Mangold; Seppo Junnila; Sweden Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aging building stock; Energy performance certificate; Energy retrofitting; Equity; GIS; Göteborg; Measured energy usage; Multi-family dwellings; Social sustainability; Tenure;

    Sammanfattning : In Sweden and many European countries, the building stock increased at a rapid pace during the period of 1950-1975. This aging building stock is in need of renovation which is a challenge and an opportunity in reaching the energy performance targets as well as decreasing societal inequities. LÄS MER
