  1. 1. Modeling and Compensation of Polarization Effects in Fiber-Optic Communication Systems

    Författare :Cristian Bogdan Czegledi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear compensation; Channel model; model-based; polarization demultiplexing; polarization-mode dispersion; polarization drift; backpropagation; PMD; DBP;

    Sammanfattning : Optical communication systems that exploit the orthogonality between two polarizations of light convey information over optical fibers by modulating data over the two polarizations. In an idealized scenario, the two polarizations propagate through the fiber without interfering. LÄS MER

  3. 2. Toxicological studies of di-n-butyl phthalate (DBP) : Impact on the reproductive system and gut microbiota

    Författare :Radwa Almamoun; Oskar Karlsson; Paula Pierozan; Harri Alenius; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dibutyl phthalate; Antiandrogen; Gut microbiota; Reproductive toxicity; Endocrine disrupting chemicals; Environmental contaminants; Phthalates; Plastics; 3D cell culture model; Exposome; Toxicology; Environmental Sciences; miljövetenskap;

    Sammanfattning : The potential health impact of exposure to anthropogenic chemicals has raised major concerns worldwide. Phthalates are mainly used in the plastic industry and have been associated with adverse effects in humans. Di-n-butyl phthalate (DBP) is one of the dominant phthalates with a ubiquitous presence in the environment. LÄS MER

  4. 3. In vitro and in vivo studies on the toxicology of di-n-butyl phthalate (DBP) : Effects on reproductive, endocrine, and immune systems

    Författare :Liselott Källsten; Oskar Karlsson; Paula Pierozan; Jonathan W. Martin; Jorma Toppari; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dibutyl phthalate; Endocrine disrupting chemicals; Male reproductive health; Phthalates; Immunotoxicity; Toxicology; Steroidogenesis; Environmental Sciences; miljövetenskap;

    Sammanfattning : Chemical pollution is an increasing societal problem and has a major impact on human and environmental health. One important source of chemical pollution is plastic, which contains many different compounds with often largely unknown hazards. LÄS MER

  5. 4. Uncharted Waters : Non-target analysis of disinfection by-products in drinking water

    Författare :Anna Andersson; David Bastviken; Henrik Kylin; David Reckhow; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water treatment technologies; chemical disinfection; FT-ICR MS; bioassays; Vattenreningstekniker; klor; kloramin; FT-ICR MS; effektbaserad analys;

    Sammanfattning : Disinfection by-products (DBPs) are potentially toxic compounds formed when drinking water is treated with disinfectants, such as chlorine or chloramine. A large proportion of the exposure to DBPs is still unknown and the health risks observed through epidemiological studies cannot be explained by DBPs known today. LÄS MER

  7. 5. The occurrence of disinfection by-products in four Swedish drinking waterworks

    Författare :Muhammad Jamshaid Ashiq; David Bastviken; Henrik Kylin; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Disinfection by-products (DBPs) are unwanted, potentially toxic compounds formed when drinking water is disinfected with chemical disinfectants such as chlorine or chloramine. The levels of DBPs produced depends on parameters, such as levels of natural organic matter (NOM) and the nature and concentration of chemical disinfectant used. LÄS MER
