  2. 1. The measurement of chemical persistence in the field by benchmarking : Theory and Experiment

    Author : Hongyan Zou; Michael McLachlan; Keri Hornbuckle; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chemical benchmarking; persistence; half-lives; modeling; threshold benchmarking; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Persistence is one of the core criteria in chemical exposure and hazard assessment. It is often defined as the half-life for the removal of a chemical from a specified environment by transformation. Chemicals with long transformation half-lives may pose high risks for wildlife or humans and be subject to long-range transport to remote areas. READ MORE

  4. 2. Exploitation of interactions with the neonatal Fc receptor to manipulate biological half-lives for therapeutic applications

    Author : Shengze Yu; Torbjörn Gräslund; Mats Ohlin; KTH; []
    Keywords : Glioblastoma Multiforme GBM ; Prolacin Prl ; Prolacin receptor PrlR ; Prolactin antagonist PrlRA ; Albumin binding domain ABD ; serum albumin SA ; half-life extension; FcRn; Affibody; human growth hormone hGH ; immunoglobulin G IgG ; blocking; autoimmune disease; Bioteknologi; Biotechnology;

    Abstract : Protein engineering provides powerful tools to create useful proteins with desired properties. In this thesis, rational design principles have been used for development of fusion proteins that can interact with the neonatal Fc receptor (FcRn) for potential medical applications. FcRn is widely expressed in the human body.

  5. 3. How to estimate environmental persistence : Understanding persistence of organic micropollutants in rivers from a multidisciplinary perspective

    Author : Claudia Coll Mora; Anna Sobek; Matthew MacLeod; Emma J. Rosi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic micropollutants; biodegradation; persistence; rivers; flume mesocosms; Junge relationships; OECD 308 bottle incubations; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Organic micropollutants such as food additives, pharmaceuticals and personal care products are found in rivers worldwide. Persistence is a key criteria in chemical risk assessment as micropollutants that are persistent pose an exposure hazard to humans and the environment. READ MORE

  6. 4. Design, Synthesis and Evaluation of Photoswitches for Molecular Solar Thermal Energy Storage Systems

    Author : Maria Quant; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Solar fuels; Norbornadiene; Tetracyclooctane.; Quadricyclane; Energy storage and release; Solar energy; Photoswitches; Molecular solar thermal energy storage; Diels-Alder reaction; Bicyclooctadiene; Energy conversion;

    Abstract : To meet the future energy demands and handle climate changes, new sustainable energy sources must be developed. Over the last decades, great scientific progress on harvesting solar energy has been made, but storing the energy is still a challenge. READ MORE

  7. 5. On Alpha-decay and Alpha Clustering

    Author : Gordana Dodig Crnkovic; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The half-life for the Alpha-decay of 212 Po is calculated within a harmonic oscillator representation. Clustering induced by the nuclear interaction appear by considering alarge configuration space. The role of clusterisation in the alpha-decay process isclearly demonstrated. READ MORE
