  • A simplified approach for determining the hydrometer's dynamic settling depth in particle-size analysis
  • 2012
  • The concept of resilience in ecology has been expanded into a framework to analyse human-environment dynamics. The extension of resilience notions to society has important limits, particularly its conceptualization of social change. The paper argues
  • that this stems from the lack of attention to normative and epistemological issues underlying the notion of ‘social resilience’. The AA. suggest that critically examining the role of knowledge at the intersections between social and environmental dynamics helps

  • From rebel governance to state consolidation - Dynamics of loyalty and the securitisation of the state of Eritrea
  • 2012
  • AIDS-affected children, family collectives and the social dynamics of care in Ethiopia
  • 2012
  • Differentiation of temporal water level dynamics in the Besko and Klimkówka Reservoirs (the low Beskids, Poland)
  • , but the reservoirs operate on rivers with different hydrological regimes (the Wisłok River and the Ropa River). The performed analysis shows that during the year, the analyzed reservoirs are characterized by different water level dynamics. The water level changes

  • Mudboil and ice-wedge dynamics investigated by electrical resistivity tomography, ground temperatures and surface movements in Svalbard
  • controlled by thermo-hydrological dynamics and (3) spatial variation in resistivity reflecting desiccation in summer and intensive ice segregation in winter. These results demonstrate ERT as a useful complementary technique for monitoring active-layer depths

  • Coupled control of land use and topography on nitrate-nitrogen dynamics in three adjacent watersheds
  • To investigate the factors controlling nitrate-nitrogen dynamics during snowmelt season and rainfall events, this study was conducted in 3 adjacent headwater stream watersheds with coupled land use and topography characteristics in eastern Hokkaido
  • 2012
  • Rock fall dynamics and deposition : an integrated analysis of the 2009 Ahwiyah Point rock fall, Yosemite National Park, USA
  • The AA. analyzed a combination of airborne and terrestrial LiDAR, high-resolution photography, seismic, and acoustic data in order to gain insights into the initiation, dynamics, and talus deposition of a complex rock fall in eastern Yosemite Valley
