1. 1. Rapid expansion of roof mounted PV systems in commercial facilities - How can they be insured?

   Master-uppsats, Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Författare :Erik Lindén; [2023]
   Nyckelord :PV system fires; PV component failures; PV regulations; future PV regulations; PV risk assessment; PV risk evaluation; PV insurance price; Technology and Engineering;

   Sammanfattning : PV system components that are exposed to unmanageable strain can be overheated, which subsequently results in a fire ignition. Common failure factors are poor component quality, mechanical exposure due to natural phenomena and poor craftmanship. The underlying problem is that PV regulations are lacking in quality or are non-existent. LÄS MER

3. 2. Identification of restoration hotspots in landscape-scale green infrastructure planning based on model-predicted connectivity forest

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Xiaoming Wang; [2023]
   Nyckelord :boreal forest; conservation; restoration; connectivity; green infrastructure; GIS; Sweden; Earth and Environmental Sciences;

   Sammanfattning : Boreal forest landscapes have undergone severe anthropogenic fragmentation and their enormous values concerning, e.g., ecosystem service, biodiversity and culture are hazarded. LÄS MER

4. 3. Increased carbon sequestration of actively restored tropical forests in Sabah, Malaysia : a comparison of natural regeneration and active restoration

   Master-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Johan Engström; [2023]
   Nyckelord :Degraded tropical forest; Active restoration; Carbon sequestration; Natural regeneration; Enrichment planting; Biomass accumulation;

   Sammanfattning : As restoration with assisted natural regeneration and enrichment planting becomes a more important and popular method to restore ecosystem services and mitigate negative climate effects, these treatments and their effectiveness is heavily debated. There are three main groups of opinions regarding restoration, one is that humans actively need to help nature recover and the second is that nature itself does a better job without our help and the third is somewhere in between.

5. 4. Making nets more acoustically visible : Floats as passive mitigation measures to reduce bycatch of harbour porpoise (Phocoena phocoena) in gillnets

   Master-uppsats, SLU/Dept. Of Aquatic Resources

   Författare :Frida Rosshagen; [2023]
   Nyckelord :toothed whales; harbour porpoise; Phocoena phocoena; incidental capture; bycatch; fisheries; fishing gear; ; gillnet; mitigation; reduction; low-cost; passive acoustic reflector; float;

   Sammanfattning : Incidental capture in fishing gear is today affecting at least 112 marine mammal species worldwide and for many smaller toothed whale species (Odontocete), gillnets are considered to be the largest problem. Although some effective mitigation measures exists, these are often context specific and many might be hard to implement due to reasons such as high costs and maintenance. LÄS MER

7. 5. Fasta och rörliga solskydd : En fallstudie på två skolor

   Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Författare :Mustafa Ekk; Homam Alsakati; Antouine Matloub; [2022]
   Nyckelord :Dynamic solar shading; fixed solar shading; thermal comfort; PPD-index; IDA-ICE; solar shading; energy; Dynamiskt solskydd; fasta solskydd; termisk komfort; PPD-index; IDA-ICE; solavskärmning; energi.;

   Sammanfattning : Purpose: During the summer, overheating in buildings is becoming more common, but at the same time the passive heat from the sun during the winter can be utilized. This project investigates which solar shading is the best alternative to use in new buildings in Kungsbacka municipality. LÄS MER
