Object-oriented image analysis for detection of the barren karst areas. A case study: the central sector of the Mehedinti Mountains (Southern Carpathians)
The barren karst areas are not typically for the karst regions of the morphoclimatic system of temperate zone. Nevertheless the importance of assessing the extension and degree of compactness of bare karst is grounded by the fact that these areas represent both particular geomorphological landscape, with specific implications in the karstic processes, and diverse and fragile ecosystems. The touristic potential of barren karst is important too. The

The viscoelastic properties of 2% poly(ethylene glycol) aqueous solutions containing Laponite RD from 1% to 4% were investigated by oscillatory and flow measurements in the temperature range of 15-40 degrees C. The enhancement of the clay content from mixture causes the increase of the viscoelastic moduli and the change of the flow from liquid-like behavior (Maxwellian fluid) to a solid-like one at a set temperature. The longest relaxation times

The possibility of finding multistability in the density and current of an interacting nanoscale junction coupled to semi-infinite leads is studied at various levels of approximation. The system is driven out of equilibrium by an external bias and the nonequilibrium properties are determined by real-time propagation using both time-dependent density functional theory (TDDFT) and many-body perturbation theory (MBPT). In TDDFT the exchange-correlation
