    Author : Anna Mentor; Maria Jönsson; Patrick Babin; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; Mixtures; Developmental toxicology; Endocrine disrupting chemicals; Metabolism; Feminization; Zebrafish; Chicken embryo; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi;

    Abstract : Humans and wildlife are continuously exposed to mixtures of environmental pollutants. Mixture toxicity can be challenging to predict due to interactions between chemicals and thus whole-mixture approaches are crucial in toxicology. READ MORE

  3. 3. Ageing of Asphalt Mixtures : Micro-scale and mixture morphology investigation

    Author : Prabir Kumar Das; Björn Birgisson; Nicole Kringos; Andreas Loizos; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Ageing; Aggregate packing; Atomic force microscopy; Asphalt mixture; Bitumen; Diffusion; Finite element analysis; Gradation; Micro-structure; Mixture morphology; Oxidative ageing; Surface ageing;

    Abstract : There are many variables that affect the viscoelastic properties of asphalt mixtures with time, among which age hardening may be considered one of the important ones. Age hardening of asphalt mixtures is an irreversible process, which contributes to a reduction of the durability of pavements and eventually increases the maintenance cost. READ MORE

  4. 4. Risk assessment of chemical mixtures in the aquatic environment

    Author : Mikael Gustavsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemical mixtures; Risk assessment; Pesticides; Industrial chemicals; REACH; Chemical monitoring;

    Abstract : The total chemical production within the European Union amounts to more than 300 million tonnes per year, of which 140 million tonnes are considered as hazardous to the environment. In order to ensure that these chemicals do not have harmful effects under normal use, likely environmental concentrations are compared to assumed environmentally safe concentration, and only if the resulting risk is deemed acceptable is the product or chemical allowed for use.

  5. 5. Dielectric Relaxation in Dielectric Mixtures

    Author : Enis Tuncer; Chalmers University of Technology; []
    Keywords : ;

    Abstract : In this thesis dielectric properties of both ideal composite structures and polymeric composite materials were investigated. Numerical calculations were performed to simulate frequency response of interfacial polarization using the finite element method in two dimensions. READ MORE
