2. 1. Contributions to Emission, Exposure and Risk Assessment of Nanomaterials

   Author : Rickard Arvidsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; particle flow analysis; emission assessment; titanium dioxide; graphene; silver; risk assessment; exposure assessment; Nanomaterials; substance flow analysis.;

   Abstract : In recent years, synthetic nanomaterials have begun to be produced and used in increasingly larger volumes. These materials may cause new or increased risks to the environment, but no harmonized methods for structured assessment of their environmental risks exist. READ MORE

4. 2. Improving alternatives assessment of plastic additives : exploring in silico tools to identify less hazardous flame retardants

   Author : Ziye Zheng; Patrik L. Andersson; Hans Peter Arp; Gregory Peters; Gerrit Schüürmann; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemical alternatives assessment; plastic additives; flame retardants; hazard; emission; in silico; modeling; quantitative structure-activity relationship QSAR ; multi-criteria decision analysis MCDA ; environmental science; miljövetenskap; organisk kemi; Organic Chemistry; ekotoxikologi; Ecotoxicology; Toxicology; toxikologi;

   Abstract : Alternatives assessment is applied for replacing hazardous chemicals with viable, safer substitutes. High quality experimental hazard data, however, are usually unavailable for this purpose, and obtaining in silico data is the only approach to fill in data gaps. READ MORE

5. 3. Air Pollution from Ships - Emission Measurements and Impact Assessments

   Author : Hulda Winnes; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel; air pollution; ships; impact assessment; emission measurement; ship emissions; emission inventory; manoeuvring ships; abatement;

   Abstract : Environmental impact and air pollution from ships have received increasing attention the last decades. Due to combustion characteristics of typical marine engines and a wide spread use of unrefined fuel, the global fleet emits significant amounts of SO2, NOX and particles to air. READ MORE

6. 4. ELM: Environmental Assessment of Fuel Supply Systems for Vehicle Fleets

   Author : Magnus Blinge; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; exergy; biomass; alternative motor fuel; wnvironment; transportation; renewable; energy; Life Cycle Assessment; logistics; emission;

   Abstract : This thesis is based on the idea of applying a logistics approach to fuel supply systems. The complete supply chain from energy raw material to end use in the vehicle is analysed while keeping track of energy conversion efficiency, exergy consumption and emissions to air. READ MORE

7. 5. Assessment of Graft Effects and Function in Cell Replacement Therapy for Parkinson's Disease

   Author : Peter Hagell; Äldres hälsa och personcentrerad vård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; neuropsychology; Neurology; measurement; psychometrics; perceived health; dyskinesias; assessment; striatum; positron emission tomography; dopamine; Parkinson s disease; transplantation;

   Abstract : This explorative study aimed to apply, develop, and evaluate assessment methods at various levels in cell replacement therapy for Parkinson’s disease (PD). Observed motor effects in five grafted patients support that timed motor tasks and clinical ratings of parkinsonism are able to monitor motor function, but their psychometric properties need further attention.
