1. The influence of climate, population density, tree species and land cover on fire pattern in mainland Portugal
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Forest fires in mainland Portugal are becoming more extreme, resulting in increasingly larger burnt areas and tragic human fatalities, as was shown by the 2017 fires. Research shows that there are many natural factors contributing to such fire vulnerability conditions, such as climate, fuel continuity, forest structure, tree species types, amongst others, that are intertwined with anthropic factors than can intensity the fire vulnerability.

2. Factors influencing the generation of carbon monoxide in fires partially suppressed through water mist application
Master-uppsats, Lunds universitet/Avdelningen för BrandteknikSammanfattning : Fires in the built environment typically consist of diffusion flames with inefficient mixing of fuel and oxygen, resulting in a degree of incomplete combustion and the generation of carbon monoxide. Fire suppression systems, used to control the growth and spread of fire, influence the combustion reaction process. LÄS MER
3. Utvärdering av potential hos organiska restmaterial för avsättning i form av biokol
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Runtom på den svenska marknaden finns olika strömmar av restmaterial som idag ofta uppfattas som avfall. För att uppnå ett mer cirkulärt samhälle finns förhoppningen om att dessa restmaterial skulle kunna nyttjas i en ny applikation och anses som en resurs istället för ett avfall. LÄS MER
4. Spridning av släckvattenpartiklar : En studie på spridning av partiklar genererade från brand
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : During a fire large amounts of particles and unhealthy agents occur. Polyaromatic hydrocarbons (PAH) and toxic metals are examples among many others. These agents have a capacity to bond to particles and when the fire is extinguished, the particles can be transferred with the extinguish water into the soil and to the groundwater. LÄS MER
5. The influence of climate and land cover on wildfire patterns in the conterminous United States
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The occurrence of wildfires is greatly dependent on an ecoregions typical climate and land cover type. To investigate whether climate or land cover primarily lead to wildfires in the conterminous United States, wildfire events from 1999- 2010 are analyzed. Wildfires are divided into years and eco-divisions, a sub-form of ecoregions. LÄS MER
