1. 41. Bleeding complications following acute myocardial infarction : time trends, risk assessment and associated prognosis

   Författare :Moa Simonsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: In patients with acute myocardial infarction (MI), bleeding complications are common and associated with worse prognosis. This thesis aimed to investigate the epidemiology, risk assessment and associated outcomes of bleeding complications in patients with acute MI. LÄS MER

3. 42. Environmental, health and safety assessment of phase-change solvents for post combustion CO2 capture

   Författare :Gulnara Shavalieva; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-change solvents; carbon capture; CAMD; LCA; EHS;

   Sammanfattning : A novel class of solvents exhibiting liquid-liquid phase separation upon reaction with CO2 and/or change in temperature, promises significant reduction of energy requirement of the post combustion capture by chemical absorption. However, proceeding to a large-scale application of novel materials requires holistic evaluation of the aspects related to human health, safety, and environmental impacts currently missing for phase-change solvent alternatives.

4. 43. Hazard Identification of Anti-fouling Paints and Contaminated Sediments by the Use of Biological Tests in Brackish Water

   Författare :Jenny Karlsson; Britta Eklund; Magnus Breitholtz; Göran Dave; Stockholms universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anti-fouling paints; Toxicity tests; Hazard identification; Sediment toxicity; Ceramium tenuicorne; Nitocra spinipes; Environmental engineering; Miljöteknik; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Ecotoxicological test methods are important tools in environmental risk assessment to investigate possible adverse effects that chemical substances may cause to aquatic ecosystems. The main aim of this doctoral thesis was to identify potential toxicity (hazard) of anti-fouling compounds and paints as well as contaminated sediments. LÄS MER

5. 44. Lithium-ion Battery Safety - Assessment by Abuse Testing, Fluoride Gas Emissions and Fire Propagation

   Författare :Carl Fredrik Larsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fire; thermal runaway; gas emission; gas explosion; propagation; safety; abuse testing; Lithium-ion; cell case explosion; hydrogen fluoride;

   Sammanfattning : Lithium-ion batteries offer high energy and power densities as well as long life time but have a more narrow stability window compared to other battery types and contain reactive and flammable materials. In case of overheating the battery cell can release gas (vent) and, at temperatures of about 150-200 °C, a so called thermal runaway can occur, that is a rapid self-heated temperature increase which is typically accompanied with a large release of smoke and gas, fire and a potential cell case explosion or gas explosion.

7. 45. Inconsistencies and missing links in EU chemicals legislation

   Författare :Diana Kättström; Marlene Ågerstrand; Steffen Foss Hansen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; REACH; Cosmetic Products Regulation; Biocidal Products Regulation; CLP; new hazard classes; PBT vPvB; EDC; PMT vPvM; endocrine disruptor; Chemicals Strategy for Sustainability; Environmental Sciences; miljövetenskap;

   Sammanfattning : The EU chemicals legislation consists of the Regulation on Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) and the Regulation on Classification, Labelling, and Packaging of Substances and Mixtures (CLP), complemented by over fifty regulations and directives regulating specific uses and products. While regulating individual uses may offer a faster and simpler approach to protecting human health and the environment from hazardous chemicals, it can also lead to inconsistencies, such as gaps and overlaps.
