  4. 3. Interaction of Lightning Flashes with Wireless Communication Networks : Special Attention to Narrow Bipolar Pulses

    Författare :Mohd Riduan Ahmad; Vernon Cooray; Mahbubur Rahman; Rajeev Thottappillil; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Latitude; Lightning; Narrow bipolar pulse; Wireless network.; Engineering Science with specialization in Atmospheric Discharges; Teknisk fysik med inriktning mot atmosfäriska urladdningar;

    Sammanfattning : In this thesis, the features of electric field signatures of narrow bipolar pulses (NBPs) generated by cloud flashes are investigated and their effects on wireless communication systems are studied. A handful amount of NBPs (14.5%) have been observed to occur as part of cloud-to-ground flashes in South Malaysia. LÄS MER

  5. 4. The effect of climate on oak-based species interactions : annual number of leaf flushes and insect voltinism

    Författare :Álvaro Gaytán; Ayco J. M. Tack; Karl Gotthard; Kailen A. Mooney; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate change; food webs; latitude; leaf flush; plant-based species interactions; Quercus robur; voltinism; Ecology and Evolution; ekologi och evolution;

    Sammanfattning : Plants interact with a large diversity of organisms, including insects and microorganisms. These species interactions are strongly influenced by climate, as illustrated by the advances in plant and insect phenology in response to increasing temperatures. LÄS MER

  7. 5. Atmospheric transport of persistent organic pollutants to aquatic ecosystems

    Författare :Cecilia Agrell; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Temperature; Latitude; Deposition; PCB; Baltic Sea; Ekologi;

    Sammanfattning : The load of persistent organic pollutants (POPs) is considered high in the Baltic ecosystem. The Baltic Sea spans over 12 latitudes and the regional differences in climate affect the behavior of POPs. LÄS MER
