  1. 41. Determinants of Infant Mortality in Kenya - Analysis of Kenya DHS 2003 and 2008/9

    Magister-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Danning Liu; [2014]
    Nyckelord :infant mortality; Kenya; regional differences; demographic determinants; socio-economic determinants; proximate determinants; Business and Economics;

    Sammanfattning : Infant mortality rate is considered as sensitive indicators of living standard and socio-economic conditions of a country. It remains a big challenge for the Kenyan Government due to the high infant mortality rates as she strives to achieve the Millennium Development Goals (MDGs). LÄS MER

  3. 42. Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements

    Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Kristin Forsell; [2014]
    Nyckelord :flodpärlmussla; biologiska kvalitetsfaktorer; freshwater pearl mussel; biological quality elements;

    Sammanfattning : The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity.

  4. 43. Polygon ponds and their ostracode assemblages as bioindicators in the Indigirka Lowland (north-east Siberia)

    Master-uppsats, Institutionen för naturgeografi och kvartärgeologi (INK)

    Författare :Andrea Schneider; [2013]
    Nyckelord :arctic limnology; polygon ponds; biological indicators; freshwater ostracods; stable water isotopes;

    Sammanfattning : Freshwater ostracods (crustacea, ostracoda) are sensitive to environmental conditions, and are widely used as biological indicators for past and present environmental changes. The abundance and diversity of ostracods from permafrost areas is currently documented in scattered records with incomplete ecological characterizations. LÄS MER

  5. 44. Maturity of kerogen, petroleum generation and the application of fossils and organic matter for paleotemperature measurements

    Magister-uppsats, Limnologi; Institutionen för biologisk grundutbildning

    Författare :David Landbecker; [2011]
    Nyckelord :macrophytes; biological quality factors; lakes; nutrient level; eutrophication; Swedish EPA; assessment criteria; WFD; makrofyter; biologiska kvalitetsfaktorer; sjöar; näringsnivå; eutrofiering; Naturvårdsverket; bedömningsgrunder; Ramvattendirektivet;

    Sammanfattning : According to the Water Framework Directive of the European Union, macrophytes should be used as indicators in the ecological and environmental monitoring of lakes. In the member state Sweden the Environmental Protection Agency has elaborated assessment criteria for determining lake status based on macrophytes. LÄS MER
