   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Martin Sturdy; [2023]
   Nyckelord :Flame length; curved ceiling; Technology and Engineering;

   Sammanfattning : In this Master thesis project the factors affecting flame extension under flat and curved ceilings have been investigated. An experimental campaign was carried out in Lund University’s Fire Lab using a propane gas burner and heptane pool fire in different positions and heat release rates within the setups. LÄS MER

3. 7. Riskreducerande åtgärder för vätgasläckage

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Jacob Kuhs; Oskar Zubac; [2022]
   Nyckelord :Hydrogen; Risk reduction measures; Risk mitigation; Gas leak detection; Leakage sound; Ultrasonic; Ultrasound; Gas leak detector; USGD; UGLD; Fire detection; Flame detector; Flame spectroscopy; Spectrum; Technology and Engineering;

   Sammanfattning : Hydrogen use increase and so does the knowledge about its risks, but not necessarily about how to handle these risks. Limited literature is available about risk mitigation for hydrogen use, the objective of this thesis is to increase this knowledge. LÄS MER

4. 8. Fire Risk and Hazard Analysis of Lithium-Ion Battery Technologies in Underground Facilities: A Literature Review

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Sean Meehan; [2022]
   Nyckelord :lithium-ion battery; hazards; risks; thermal runaway; detection; fire protection; Technology and Engineering;

   Sammanfattning : The past decades have seen an exponential growth of the lithium-ion battery (LIB) market as use of this high-energy storage has found applications in nearly every industry. The European Organization for Nuclear Research (CERN) is interested in implementing this technology within their underground network and this literature review is intended to assist with addressing fire and safety concerns.

5. 9. Eld och lågor, eller? : En kvantitativ studie om tolkningen av idiom

   Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet/Institutionen för språk, litteratur och interkultur (from 2013)

   Författare :Caroline Ahlstrand; [2022]
   Nyckelord :Idiom; fixed phrases; conventionalized phrases; opacity; Idiom; fasta fraser; konventionaliserade fraser; ogenomskinlighet;

   Sammanfattning : The amin with this paper is to investigate how a few of today’s idioms are interpreted, if there are any difference between generations in the interpretation and if the younger generation in higher extent than the older tends to interpret them in other ways. This have been investigated trough a quantitative web-based survey there the respondents were asked to state their interpretation of twelve idioms, also answer a few questions regarding their use of idioms.

7. 10. The Heat reducing Effects of Reflective Clothing in Firefighting : A study on the efficiency of reflective textiles in personal protective equipment

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Albin Henning; [2022]
   Nyckelord :Firefighter; Reflective textiles; Radiant heat; Protective equipment;

   Sammanfattning : Modern firefighter protective equipment is excellent at protecting firefighters from surrounding heat, but how effective is at deflecting incoming radiant heat, and would the use of more reflective textiles, be able to further increase the equipment’s protective properties? This study aims to understand the different properties that reflective materials, compared to standard firefighter outer layers, have against radiative heat flux. The textiles of firefighter turnout gear and the reflective textiles used in the smelting industry have been examined when exposed to varying levels of radiant heat in a cone calorimeter. LÄS MER
