  1. 1. Persistency, bioaccumulation and toxicity assessment of selected brominated flame retardants

    Författare :Jenny Rattfelt Nyholm; Patrik L. Andersson; Peter Haglund; Mats Tysklind; Walter Vetter; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; persistence; bioaccumulation; toxicity; biodegradation; biotransformation; PBT; read across; soil; earthworm; zebrafish; copepod; BFRs; polybrominated diphenyl ethers; tetrabromobisphenol A; hexabromocyclododecane; hexabromobenzene; 2; 4; 6-tribromophenol; tetrabromobisphenol A; 2-hydroxyethyl ether; 1; 2-dibromo-4- 1; 2-dibromoethyl cyclohexane; Environmental chemistry; Miljökemi;

    Sammanfattning : Brominated flame retardants (BFRs) are chemicals used in e.g. electronic equipment, textiles and plastics for the prevention of fire. Over recent decades, concern has been raised regarding some heavily used BFRs, since the levels in the environment have been increasing. LÄS MER

  3. 2. Inconsistencies and missing links in EU chemicals legislation

    Författare :Diana Kättström; Marlene Ågerstrand; Steffen Foss Hansen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; REACH; Cosmetic Products Regulation; Biocidal Products Regulation; CLP; new hazard classes; PBT vPvB; EDC; PMT vPvM; endocrine disruptor; Chemicals Strategy for Sustainability; Environmental Sciences; miljövetenskap;

    Sammanfattning : The EU chemicals legislation consists of the Regulation on Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) and the Regulation on Classification, Labelling, and Packaging of Substances and Mixtures (CLP), complemented by over fifty regulations and directives regulating specific uses and products. While regulating individual uses may offer a faster and simpler approach to protecting human health and the environment from hazardous chemicals, it can also lead to inconsistencies, such as gaps and overlaps.

  4. 3. Targeted Property-Based Testing with Applications in Sensor Networks

    Författare :Andreas Löscher; Konstantinos Sagonas; Thiemo Voigt; John Hughes; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software Testing; Search-Based Software Testing; Property-Based Testing; Datavetenskap; Computer Science;

    Sammanfattning : Testing is a fundamental part of modern software development, as it unveils bugs in the system under test and gives confidence in their correctness. Testing is often a laborious task as it typically requires to write by hand a plethora of test cases to test a system thoroughly. LÄS MER

  5. 4. Testing Safety-Critical Systems using Fault Injection and Property-Based Testing

    Författare :Benjamin Vedder; Magnus Jonsson; Andreas Johansson; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Injection; FaultCheck; Property-Based Testing; Simulation; Fault Model; Quadcopter; E2E;

    Sammanfattning : Testing software-intensive systems can be challenging, especially when safety requirements are involved. Property-Based Testing (PBT) is a software testing technique where properties about software are specified and thousands of test cases with a wide range of inputs are automatically generated based on these properties.

  7. 5. Dose Escalation with High Dose Rate Brachytherapy or Protons in Curative Radiotherapy of Prostate Cancer

    Författare :Lennart Åström; Lars Holmberg; Gunilla Enblad; Henrik Grönberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; radiotherapy; brachytherapy; high dose rate; protons; PSA bounce;

    Sammanfattning : The aim of the thesis was to study the outcome and side effects after dose-escalated radiotherapy with high dose rate brachytherapy (HDR-BT) or proton beam therapy (PBT) boost in prostate cancer.The first cohorts of men in Sweden treated with either HDR-BT or PBT in combination with conventional photon beam therapy (2 Gray (Gy) fractions to 50 Gy) were analysed.
