    Sammanfattning : Chemistry has a tremendous impact on everyone’s life, although society does not always realize its power and ubiquity. In recent years, improved economy and sustainability of chemical processes has become a worldwide priority. LÄS MER

  3. 2. The Role of Carbon-Nitrogen Interactions for Terrestrial Ecosystem Dynamics under Global Change - a modelling perspective

    Författare :David Wårlind; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C-N Interactions; Ecosystem Modelling; DGVM; Nitrogen; Carbon; Climate Change;

    Sammanfattning : The nature of future climate change will depend on anthropogenic emissions of CO2, as well as climate- and CO2-mediated feedbacks through carbon (C) cycling in both terrestrial ecosystems and oceans. Terrestrial ecosystems remove presently about 25% of the anthropogenic CO2 fossil-fuel and land-use change emissions, but to attribute which mechanisms cause this uptake, and the key regions where it occurs, is a challenging task.

  4. 3. Scalable Analysis of Large Datasets in Life Sciences

    Författare :Laeeq Ahmed; Erwin Laure; Ola Spjuth; Ake Edlund; Vincent Breton; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Big Data; Apache Spark; Virtual Screening; EEG; Cloud Computing; Life Sciences; Machine Learning; Computer Science; Datalogi;

    Sammanfattning : We are experiencing a deluge of data in all fields of scientific and business research, particularly in the life sciences, due to the development of better instrumentation and the rapid advancements that have occurred in information technology in recent times. There are major challenges when it comes to handling such large amounts of data. LÄS MER

  5. 4. Stress-induced BVOC emissions from forests in Sweden

    Författare :Erica Jaakkola; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Volatile organic compounds; Plant stress; Forests; Volatile emissions; spruce bark beetle infestations; ozone stress; wildfire recovery; Picea abies Norway spruce ; Betula pubescens ssp. czerepanovii; Pinus sylvestris Scots pine ; sweden;

    Sammanfattning : A changing climate is expected to lead to more extreme weather events, such as an increased frequency of droughts and forest fires. Changing forest conditions can offer benefits to species such as insects, including bark borers that thrive in warm conditions. LÄS MER

  7. 5. Enhancing the circular economy: Resource recovery through thermochemical conversion processes of landfill waste and biomass

    Författare :Ilman Nuran Zaini; Weihong Yang; Pär Jönsson; Ashwani K. Gupta; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; pyrolysis; waste-to-energy; landfill waste; hydrogen production; circular economy; municipal solid waste; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Currently, the global economy looses a considerable amount of potential secondary raw materials from the disposed waste streams. Furthermore, the existing landfill sites that often do not have proper environmental protection technologies pose a long-lasting risk for the environment, which urge immediate actions for landfill remediations.
