  3. 7. The Use of Press Archives in the Temporal and Spatial Analysis of Rainfall-Induced Landslides in Tegucigalpa, Honduras, 1980-2005

    Författare :Elias Garcia-Urquia; Kristofer Gamstedt; José Cepeda; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; press archives; landslide database; urban landslides; critical rainfall intensity; antecedent rainfall; rainfall frequency contour lines; matrix method; landslide susceptibility index; Tegucigalpa; Honduras; Hurricane Mitch; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

    Sammanfattning : The scarcity of data poses a challenging obstacle for the study of natural disasters, especially in developing countries where the social vulnerability plays as important a role as the physical vulnerability.  The work presented in this thesis is oriented towards the demonstration of the usefulness of press archives as a data source for the temporal and spatial analysis of landslides in Tegucigalpa, Honduras for the period between 1980 and 2005.

  5. 9. Clinical and Experimental Aspects of Phonetogram Analysis

    Författare :Leif Åkerlund; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; subglottal pressure.; sound pressure level; semitones; phonetogram contours; phonetogram; intensity; Fundamental frequency; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Sammanfattning : A phonetogram is a diagram displaying sound pressure levels (SPL) of softest and loudest possible phonation over the entire fundamental frequency range (F0) of a voice. Female singers mean phonetogram had a significantly higher upper contour than female nonsingers. LÄS MER

  7. 10. Hydrological effects of water harvesting techniques

    Författare :Slah Nasri; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil mechanics; Väg- och vattenbyggnadsteknik; offshore technology; hydraulic engineering; hydrological effects; Civil engineering; rainwater harvesting; erosion;

    Sammanfattning : The thesis investigates hydrological effects of large-scale water harvesting techniques on local water balances as well as sediment erosion. The techniques of tabias, soil contour ridges and small hill reservoirs are investigated. Pertinent processes are observed and simulated using various hydrological models.. LÄS MER
