The potential of global solar radiation in the Silesia region as a renewable source of energy
Environmental & Socio-economic Studies, 2016 Historically, Silesia has been at the centre of the Polish coal industry for many years and thus has experienced poorer air quality compared to other voivodeships.

Insights Into the Mechanisms Controlling the Residual Strength of Bio‐cemented Sands
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 6, Page 2711-2726, 25 April 2026.ABSTRACT Microbially induced carbonate precipitation (MICP) is an emerging technique for enhancing the mechanical properties of granular soils. Although several experimental studies have reported increased shear strength in MICP‐treated soils at both peak and residual states, other findings have shown reductions in residual strength compared to ...

Convergence: Are the Eurozone countries too different? Bertelsmann Stiftung EUROPA Briefing 2017 [PDF]
, 2017 The Eurozone countries are economically different. The crisis has rendered some of these differences more acute and this could destabilize the currency union.

Evaluation of LISS-III Sensor Data of IRS-P6 Satellite for Detection Saline Soils (Case Study: Najmabad Region) [PDF]
Desert, 2012 Soil Salinity has been a large problem in arid and semi arid regions. Preparation of such maps is useful for Natural resource managers. Old methods of preparing such maps require a lot of time and cost.

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.Abstract We present idealized 3‐D discrete element simulations exploring how varying boundary roughness and grain‐size distribution affect bulk granular‐rheology and basal‐force distributions. Boundary roughness has a direct control on the internal static friction coefficient.

Imbalances: Should the EU intervene? Bertelsmann Stiftung EUROPA Briefing 2017 [PDF]
, 2017 Economic imbalances keep recurring in the EU. Differences in trade balances dominate the debate. Germany has been generating very high surpluses for years and meets criticism for this reason. Are imbalances a threat to the EU, and what role does the euro

Earth and Space Science, Volume 12, Issue 10, October 2025.Abstract An accurate geoid has important consequences for many fields such as engineering applications, underground resource exploration, geophysical surveys, etc. Its precise determination relies on two key data sets: gravity measurements and high‐resolution elevation data, both of which are critical for achieving reliable results.

Monitoring bulk material pressure on bottom of storage using DEM
Open Engineering, 2019 This article focuses on the experimental verification of a mathematical derivation of Janssen’s theory, which describes the distribution of pressures within the bulk material and pressure distribution on the walls of storage facilities.

River Research and Applications, Volume 41, Issue 7, Page 1418-1426, September 2025.ABSTRACT Streambank erosion is an important source of sediment to river systems but is difficult to quantify at watershed scales. In this study, high‐resolution Light Detection and Ranging (LiDAR) measurements collected from 2009 and 2020 were used to quantify the difference in land surface elevation that occurred along the fourth and fifth‐order ...

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 5, Page 1420-1436, 10 April 2025.ABSTRACT In this work, a fatigue crack propagation model is proposed using the two‐dimensional discrete element method (DEM). The challenge lies in describing the small progressive fatigue crack growth within a single cycle, which is typically much smaller than the size of the smallest particles, making it difficult to continuously capture the loss of ...
