  2. 1. Stormy records from peat bogs in south-west Sweden : implications for regional climatic variability and vegetation changes during the past 6500 years

    Author : Rixt de Jong; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Holocene climate; south-west Sweden; aeolian activity; humidity changes; vegetation development; REVEALS vegetation modelling; atmospheric circulation changes; peat sediments;

    Abstract : This thesis aims to reconstruct and explain variations in storm activity, humidity, vegetation composition and land cover in south-west Sweden during the past 6500 years. Two ombrotrophic bogs, Store Mosse and Undarsmosse, situated on the coastal plain of Halland, were selected for this purpose. READ MORE

  5. 3. Late Holocene humidity variability in central Sweden

    Author : Sofia Andersson; Stefan Wastegård; Gunhild Rosqvist; Kristian Schoning; Frank Chambers; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; humidity change; stable isotopes; Chara spp; Pisidium spp; testate amoebae assemblages; humification; C N ratio; late Holocene; central Sweden; Quaternary geology; Kvartärgeologi; kvartärgeologi; Quarternary Geology;

    Abstract : The aim of this thesis was to reconstruct humidity variability in central Sweden during the late Holocene. A multi-proxy approach was used to infer humidity changes as recorded in a lake and a mire. Age-models were constructed based on radiocarbon dating and the Askja-1875 tephra. READ MORE

  6. 4. Evaluating Tropical Upper-tropospheric Water in Climate Models Using Satellite Data

    Author : Marston Sheldon Johnston; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ECHAM6; Humidity; Climate; CAM5; IWC; Clouds; EC-Earth;

    Abstract : Measuring and simulating moist processes in the tropical upper troposphere are difficult tasks. Humidity in this region of the atmosphere is mainly supplied by deep convection and, problems with simulated convection areknown to be a major contributor to uncertainties in climate model projections.

  7. 5. Dielectric properties of poly(ethyelene-co-butyl acrylate) filled with Alumina nanoparticles

    Author : Nadejda Jäverberg; Hans Edin; Eva Mårtensson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanocomposites; poly ethylene-co-butyl acrylate ; EBA; alumina; dielectric permittivity; absorbed water; humidity; temperature; dielectric spectroscopy; partial discharge; electrical treeing; Electrical engineering; Elektroteknik;

    Abstract : In this work dielectric properties of the poly(ethylene-co-butyl acrylate)filled with alumina nanoparticles are evaluated. These nanocomposite materialswere manufactured at the department of Fibre and Polymer Technology,KTH.This study is limited to the properties of general importance for the AC applications. READ MORE
