2. 6. Predicting surfacing internal erosion in moraine core dams

   Author : Hans Rönnqvist; Anders Wörman; Hans Bergh; Kaare Høeg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; internal erosion; internal stability; filters; moraine core; embankment dams; sinkholes; internal erosion assessment; Geoengineering and mining engineering; Geoteknik och gruvteknik;

   Abstract : Dams that comprise broadly and widely graded glacial materials, such as moraines, have been found to be susceptible to internal erosion, perhaps more than dams of other soil types. Internal erosion washes out fine-grained particles from the filling material; the erosion occurs within the material itself or at an interface to another dam zone, depending on the mode of initiation.

4. 7. Cognitive erosion and its implications in Alzheimer’s disease

   Author : Selina Mårdh; Thomas Karlsson; Anders Wallin; Linköpings universitet; []
   Keywords : Alzheimer’s disease; longitudinal study; mixed methods design; semantic memory; awareness; metacognition; central coherence; emotions; Alzheimers sjukdom; longitudinell studie; mixed methods design; semantiskt minne; medvetande; metakognition; central koherens; emotioner; Do Psychology;

   Abstract : The aim of the present thesis was twofold, first to map the semantic memory decline in Alzheimer patients over time, second to take the patient’s perspective and create a multifaceted picture of the individual with Alzheimer’s disease through the study of memory, awareness, central coherence and emotions. Further issues concerned how Alzheimer individuals handled their cognitive erosion in everyday life and if they were well calibrated with their spouse in disease related matters. READ MORE

5. 8. Palaeosurfaces and palaeovalleys on North Atlantic previously glaciated passive margins : reference forms for conclusions on uplift and erosion

   Author : Johan M. Bonow; Karna Lidmar-Bergström; Clas Hättestrand; Jens-Ove Näslund; Mats Olvmo; Adrian Hall; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; palaeosurface; palaeovalley; uplift; valley; incision; glacial erosion; weathering; Neogene; southern Norway; West Greenland; Earth sciences; Geovetenskap;

   Abstract : Palaeosurfaces and palaeovalleys are landforms under destruction in the present climate and/or tectonic regime, and thus mainly reflect processes not active today. Uplifted palaeosurfaces exist along the formerly glaciated passive continental margins around the North Atlantic. READ MORE

7. 10. The village that vanished : The roots of erosion in a Tanzanian village

   Author : Vesa-Matti Loiske; Ulf Sporrong; Aud Talle; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; soil erosion; soil conservation; Tanzania; Iraqw; social stratification; land tenure; Mama Issara; Giting; Hanang; Political Ecology; Scientific realism; Geography; villagization; Human geography; Kulturgeografi; Human Geography; kulturgeografi;

   Abstract : In the village'of Citing in the northern highlands of Tanzania, the factors: social stratification, land tenure, production strategies, investment patterns and the economic uncertainties of society are studied and their relationship to land degradation is examined. The main assumption of the study is that the causes of land degradation are so complex that a methodology that emphasises contextualisation has to be used. READ MORE
