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

   Author : Carl Fredrik Larsson; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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.

4. 2. Assessment of safety characteristics for Li-ion battery cells by abuse testing

   Author : Carl Fredrik Larsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; overcharge; Lithium-ion; toxic gases; abuse test; thermal runaway; short circuit; safety; battery; fire;

   Abstract : Despite the many advantages with lithium-ion batteries there can be disadvantages in form of safetyissues. In an abuse situation a Li-ion cell can undergo a thermal runaway releasing excessive heat,flammable and toxic gas emissions and eventually accompanied by dissembling/explosion and fire. READ MORE

5. 3. Neuropeptide Receptors as Treatment Targets in Alcohol Use Disorders

   Author : Abdul Maruf Asif Aziz; Annika Thorsell; David Engblom; Elizabeth Jerlhag; Linköpings universitet; []

   Abstract : Alcohol use disorder (AUD) is a complex disorder with multiple pathophysiological processes contributing to the initiation, progression and development of the disease state. AUD is a chronic relapsing disease with escalation of alcohol-intake over time in repeated cycles of tolerance, abstinence and relapse and hence, it is very difficult to treat. READ MORE

6. 4. Server-Aided Privacy-Preserving Proximity Testing

   Author : Ivan Oleinikov; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active security; MPC; privacy; secure proximity testing;

   Abstract : Proximity testing is at the core of many Location-Based online Services (LBS) which we use in our daily lives to order taxis, find places of interest nearby, connect with people. Currently, most such services expect a user to submit his location to them and trust the LBS not to abuse this information, and use it only to provide the service. READ MORE

7. 5. Characteristics and Consequences of Use of Anabolic Androgenic Steroids in Poly Substance Abuse

   Author : Anna Petersson; Ingemar Thiblin; Harrison G Pope Jr; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anabolic steroids; Crime; morbidity; mortality; substance abuse; Forensic medicine; Rättsmedicin;

   Abstract : The use of anabolic androgenic steroids (AAS) has been associated with use of illegal or unprescribed prescription drugs, as well as different adverse psychiatric effects, such as ma-nia, psychosis and hostility. Further, there is an association between use of AAS and other different risk behaviours, including carrying guns and reckless driving. READ MORE
