  2. 2. Interaction of Lightning Flashes with Wireless Communication Networks Special Attention to Narrow Bipolar Pulses

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mohd Riduan Ahmad; Uppsala universitet.; [2014]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Atmospheric transport of persistent organic pollutants to aquatic ecosystems

    University dissertation from Cecilia Agrell Ecology Building, S-223 62 Lund

    Author : Cecilia Agrell; Lund University.; Lunds universitet.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Temperature; Latitude; Deposition; PCB; Baltic Sea; Ekologi;

    Abstract : 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. READ MORE

  4. 4. Polybrominated diphenylethers in the environment - Local and long range transport

    University dissertation from Arnout ter Schure, Dept. of Ecology, Chemical Ecology and Ecotoxicology, Sölvegatan 37, 22362, Lund, Sweden

    Author : Arnout ter Schure; Lund University.; Lunds universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Substance Flow Analysis; Spatial Variation; Sources; PCB; PBDE; Latitude; Global Fractionation; Frogs; Deposition; Atmosphere; Baltic Sea; Ekologi; Temperature; Washout ratio; Ecology;

    Abstract : I have studied the sources, long range transport, and rates of flow of polybrominated diphenyl ethers (PBDEs), from the technosphere to the Baltic ecosystems. PBDEs are mainly used in polymers, which are applied in electrical equipment to prevent overheating or flashover and are produced in large quantities. READ MORE

  5. 5. The plasticity and geography of host use and the diversification of butterflies

    University dissertation from Department of Zoology, Stockholm University

    Author : Jessica Slove Davidson; Stockholms universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nymphalidae; host range; phylogeny; distribution; latitude; phylogeography; local specialisation; colonisation; host shift; polyphagy; speciation; diversification; zoologisk ekologi; Animal Ecology;

    Abstract : Our world is changing rapidly and factors like urbanisation, changed agricultural practices and climate change are causing losses in butterfly diversity. It is therefore of importance to understand the source of their diversity. READ MORE
