1. 1. Fighting flameless fires : Initiating and extinguishing self-sustainedsmoldering fires in wood pellets

   Författare :Ragni Fjellgaard Mikalsen; Vidar Frette; Bjarne C. Hagen; Ulrich Krause; Anne Steen-Hansen; Ulrich Krause; Nieves Fernandez-Anez; RISE; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel storage safety; Industrial fire; Biofuels; Smoldering; Extinguishment; Fire suppression; Fire growth; Fire spread; Heat transfer; Nonlinear dynamics; Complex systems; Combustion; Biomass energy; Synchronization; Oscillations; EMRIS;

   Sammanfattning : Smoldering fires represent domestic, environmental and industrial hazards. This flameless form of combustion is more easily initiated than flaming, and is also more persistent and difficult to extinguish. The growing demand for non-fossil fuels has increased the use of solid biofuels such as biomass. LÄS MER

3. 2. Hygroscopic Properties of Aerosols from Open-Air Burning and Controlled Combustion of Biomass

   Författare :Jenny Rissler; Kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cloud condensation nuclei; H-TDMA; CCN; hygroscopic growth; Teknik; internal and external mixture; CLAIRE; SMOCC; Physics; Fysik; Environmental chemistry; Technological sciences; Miljökemi; tandem differential mobility analyzer; slash and burn; Amazon; Biomass burning; combustion; Fysicumarkivet A:2005:Rissler;

   Sammanfattning : The major uncertainty in predicting the influence of human activities on global climate change is the effect of aerosols. Two physical properties of aerosols largely controlling their influence on climate are the particle number size distribution and the interaction of the particles with the surrounding water vapor.

4. 3. Genetic analyses of multiple myeloma and related plasma cell dyscrasias

   Författare :Therese Nilsson; Avdelningen för klinisk genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetik; cytogenetik; cytogenetics; Genetics; FISH; cytogenetic; multiple myeloma; MGUS;

   Sammanfattning : Acquired genetic changes have proved to be of diagnostic and prognostic importance in different hematologic malignancies as well as in some solid tumor types. However, although multiple myeloma (MM), an incurable disease, and its proceeding stage monoclonal gammopathy of undetermined significance (MGUS) are quite common, little is known about the karyotypic features of these plasma cell dyscrasias.

5. 4. Strategies to assess and improve prognostication of plasma cell disorders

   Författare :Charlotte Gran; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Plasma cell dyscrasias (PCD) are a group of disorders, most of which have the overproduction of monoclonal immunoglobulins (M-protein) in common. Included in the group of PCDs are both benign and treatment demanding disorders. Multiple myeloma (MM) is one of the treatment demanding PCDs and also the second most common hematological malignancy.

7. 5. Multispectral Remote Sensing and Deep Learning for Wildfire Detection

   Författare :Xikun Hu; Yifang Ban; Ioannis Gitas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active fire detection; biome; multi-criteria; Sentinel-2; Landsat-8; burned area mapping; deep learning; semantic segmentation; machine learning.; aktiv branddetektering; biom; multikriterietillvägagångssätt; Sentinel-2; Landsat-8; kartläggning av bränt område; djupinlärning; semantisk segmentering; maskininlärningsmetoderna; Geoinformatik; Geoinformatics;

   Sammanfattning : Remote sensing data has great potential for wildfire detection and monitoring with enhanced spatial resolution and temporal coverage. Earth Observation satellites have been employed to systematically monitor fire activity over large regions in two ways: (i) to detect the location of actively burning spots (during the fire event), and (ii) to map the spatial extent of the burned scars (during or after the event).
