  2. 16. Neuroblastoma SH-SY5Y and neural progenitor C17.2 cell lines as models for neurotoxicological studies​

    Author : Jessica Lundqvist; Anna Forsby; Åsa Fex Svenningsen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SH-SY5Y; C17.2; in vitro neurotoxicity; cell culture conditions; biomarkers; in vitro developmental neurotoxicity; whole genome microarray; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : We are surrounded by chemicals, thus understanding how exposure to these chemicals affect us during our life is of great social importance. In order to predict human acute toxicity of chemicals, cosmetics or drugs, development of novel in vitro test strategies is required. READ MORE

  4. 17. Allergenic Oxidation Products from Fragrance Terpenes. Chemical Analysis and Determination of Sensitizing Potency

    Author : Johanna Rudbäck; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Autoxidation; Contact allergy; Essential oils; Fragrances; Hydroperoxides; Ionization techniques; Mass spectrometry; Prehapten; Sensitization; Skin; Structure-activity relationships; Terpenes;

    Abstract : The ubiquitous presence of fragrance compounds in consumer products has resulted in a high frequency of contact allergy to fragrances in the population. For prevention purposes and according to EU regulations, cosmetics must be labeled when containing the most prominent fragrance allergens in concentrations exceeding 0. READ MORE

  5. 18. Structure and Phase Stability of Polyelectrolyte-Macroion Solutions

    Author : Marie Skepö; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; hydrophobicity; spatially distributed interaction sites; protein-polymer interaction; Monte Carlo Simulations; redissolution; phase separation; cluster; complex; Polyelectrolytes; macroions;

    Abstract : Polyelectrolytes are polymers bearing ionisable groups, which, in polar solvents, can dissociate into charged polymer chains (polyelectrolytes) and small counterions. In aqueous solutions, polyelectrolytes interact strongly with other macroions and in particular they tend to associate with objects of opposite charge and form complexes. READ MORE

  6. 19. Self-diagnosis techniques and their applications to error reduction for ultrasonic flow measurement

    Author : Jonathan Berrebi; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : Flow metering plays a major role in modern life. In the process industry, flow metering is critical in industries ranging from food processing to cosmetics. It is also essential in custody transfer or billing, as flow meters are present in gas pumps and district heating substations. READ MORE

  7. 20. Contributions to the Use of Statistical Methods for Improving Continuous Production

    Author : Francesca Capaci; Erik Vanhatalo; Bjarne Bergquist; Murat Kulahci; Johan Carlson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process industry; Continuous process; Statistical process control; Design of experiments; Process improvements; Simulation tool; Engineering process control; Kvalitetsteknik; Quality Technology Management;

    Abstract : Complexity of production processes, high computing capabilities, and massive datasets characterize today’s manufacturing environments, such as those of continuous andbatch production industries. Continuous production has spread gradually acrossdifferent industries, covering a significant part of today’s production. READ MORE
