1. 1. Development of Laser-Spectroscopic Techniques for New Detection Schemes in Combustion Diagnostics

   Författare :Johan Zetterberg; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laser-Spectroscopy; Laser Combustion Diagnostics; Rayleigh scattering; FRS; LIF; Polarization Spectroscopy; PS; IRPS;

   Sammanfattning : The thesis work, aimed at the development of laser-spectroscopic detection schemes, consists of three parts, concerned with the development and application of different techniques. The development of UV filtered Rayleigh scattering (FRS) for thermometry and fuel/air ratio measurements, using a frequency tripled, single-longitudinal-mode alexandrite laser at ~254 nm together with an isotopically enhanced mercury filter, is examined first.

3. 2. Indoor emissions and fate of flame retardants : A modelling approach

   Författare :Ioannis Liagkouridis; Ian Cousins; Anna Palm Cousins; Thomas McKone; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flame retardants; BFRs; OPFRs; indoor environment; emissions; fate; modelling; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : A significant number of consumer goods and building materials act as emission sources of flame retardants (FRs) in the indoor environment. As a result, FRs have become ubiquitous indoors raising concerns about human exposure and possible health implications. LÄS MER

4. 3. Exploring Collaboration Between the Fire and Rescue Service and New Actors : Cost-efficiency and Adaptation

   Författare :Weinholt Åsa; Jan Lundgren; Tobias Andersson Granberg; Johan Holmgren; Sofie Pilemalm; Björn Sund; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Fire and rescue service; emergency services; collaboration; new actors; first responders; costefficiency; adaptation;

   Sammanfattning : The emergency services serves an important purpose in society by ensuring that people in need, regardless of their geographical location, receives help when they fall victims to undesirable incidents. Existing resources are however often limited and concentrated to urban areas making travel distances to remote areas long. LÄS MER

5. 4. Räddningsaktörers tidiga närvaro vid akuta situationer på svensk landsbygd

   Författare :Anders Svensson; Johan Herlitz; Linnéuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ambulance nurse; Dual dispatch; Emergency care; Firefighters; First incident person; First responder; Home healthcare; Nurses experiences; Prehospital emergency care; Scene of an accident; Worry.; Health and Caring Sciences; Hälsovetenskap;

   Sammanfattning : Aim: The overall aim was to describe the first responders´ (FRs) experiences ofarriving early at emergency situations in rural areas in Sweden and the characteristicfeatures of the assignments they encounter. The four studies aimed to: describe critical incidents in which ambulance nurses experience worry in their professional life and the actions they take in order to prevent and cope with it (I), explore and describe experiences of the First Incident Person (FIP) assignment within an Fire Department (FD) (II), describe experiences of the While Waiting for the Ambulance (WWFA) assignment, as experienced by home healthcare nurses (III) and map out and describe WWFA assignments focusing on frequency, event time,CardioPulmonary Resuscitation (CPR) and survival >30 days after performed CPR (IV).

7. 5. Leaching and Transformation of Flame Retardants and Plasticizers under Simulated Landfill Conditions

   Författare :Maritha Hörsing; Bo H. Svensson; Susanne Jonsson; Anna Karlsson; Cynthia de Wit; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DEHP; BBP; tetrabromobisphenol A; TBBPA; TBBPA-DAE; TBBPA-DBPE; TBBPA-DHEE; Proban; Pyrovatex; Melamine; Environmental chemistry; Miljökemi;

   Sammanfattning : Many products used in our everyday life contain chemicals added to give them specific properties. Flame retardants (FRs) are added to prevent or retard fires in textiles, plastics etc., while plasticizers are supplied to make plastics more flexible. LÄS MER
