  2. 1. Theoretical Studies on CO2 Reduction Electrocatalysts

    Author : Xiaoyu Chen; Mårten S. G. Ahlquist; Sandra Luber; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational Chemistry; CO2 reduction; electrocatalysis; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : The atmospheric CO2 concentration has increased by more than 20% since 1980s and has now reached the highest level than at any point in the past 800 000 years. Electrochemical CO2 reductions are receiving particular in- terest as the apparatus are relatively easy to maintain and cheap to operate. READ MORE

  4. 2. Managing Urban Disaster Risk: Analysis and Adaptation Frameworks for Integrated Settlement Development Programming for the Urban Poor

    Author : Christine Wamsler; Boende och bostadsutveckling; []
    Keywords : HUMANIORA; HUMANITIES; poverty reduction; urban planning; vulnerability; adaptation; settlement development planning; development assistance; disaster; social housing; disaster risk management; prevention; mainstreaming; El Salvador; mitigation; risk accumulation; risk reduction;

    Abstract : The damage caused by the dramatic worldwide increase in ‘natural’ disasters is staggering, with the poor in developing countries being most at risk. Disasters make their already precarious living conditions worse, creating a vicious circle of poverty from which they find it hard to escape. READ MORE

  5. 3. Similarity-Based Test Effort Reduction

    Author : Daniel Flemström; Daniel Sundmark; Afzal Wasif; Eduards Enoiu; Miroslaw Staron; Emelie Engström; Vahid Garousi; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Software Testing; Computer Science; datavetenskap;

    Abstract : Embedded computer systems are all around us. We find them in everything, from dishwashers to cars and airplanes. They must always work correctly and moreover, often within certain time constraints. The software of such a system can be very large and complex, e. READ MORE

  6. 4. Obesity and IVF outcome. The hope of improvements through weight reduction

    Author : Linda Kluge; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infertility; IVF; obesity; weight reduction; live birth; patient s views; maternal outcome; perinatal outcome;

    Abstract : Background: Female obesity is associated with decreased live birth rate (LBR) after in vitro fertilization (IVF) and adverse maternal and perinatal outcomes are increased in obese women compared to normal weight women after spontaneous conceived pregnancies. If the same applies in pregnancies achieved after IVF is scarcely investigated. READ MORE

  7. 5. Iron-nitrogen containing carbon catalysts for oxygen reduction in fuel cells

    Author : Caroline Janson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; active site; mesoporous carbon; fuel cell; electron paramagnetic resonance; oxygen reduction reaction; cathode catalyst; non-precious metal catalyst;

    Abstract : New solutions to efficiently convert energy are needed to mitigate global climate changes and sustain the needs of the growing population. An energy device with high potential is the proton exchange membrane (PEM) fuel cell. PEM fuel cells can convert chemical energy to electrical energy with extraordinary high conversion efficiency.
