Hybrid nanocomposite materials made out of integrated inorganic nanoparticles within an organic polymeric matrix canbe foundasgels, thermoplastics, thermosets or elastomers. This class of materials can exhibit the combined advantages of both the integrated nanoparticles, in terms of optical and electrical properties, and the processability of the polymeric matrix. As a result, bulk modification...

The Thebes Limestone Formation of Lower Eocene age is one the most extensive rock units in Egypt. It importance to apogee ancient Egyptian civilization, particularly Luxor (South-Central Egypt), where formation hosts Theban Necropolis, a group funerary chambers and temples from New Kingdom era (3500–3000 BP). In this work, we investigated petrophysical mechanical properties (e.g., strength, cri...

A chemical budget analysis for Williams Lake, Minnesota, tracks the seasonal progression of carbon inputs and outputs. CO, exchanges with the atmosphere reverse seasonally, with uptake by the lake in summer preceded and followed by larger losses to the atmosphere. Calcium bicarbonate-rich groundwaters seep steadily into the lake, augmented by remobilization of lacustrine marls. Most of the carb...

Abstract Cenomanian strata of the Elbtal Group (Saxony, eastern Germany) reflect a major global sea-level rise and contain, in certain intervals, green authigenic clay mineral abundance. Based on integrated study five new core sections, environmental background spatio-temporal patterns these glauconitic are reconstructed some general preconditions allegedly needed for glaucony formation critica...

Abstract Mantle-derived volcanic rocks from the Subbetic hyperextended basin in SE Spain provide new insights into composition and mechanical behavior of mantle during continental rifting. The present study describes a sequential restored cross-section along with geochemical characteristics basaltic interbedded within Mesozoic succession basin. Sedimentary stacking patterns minibasins above mob...

The pollution of surface waters, due to the demographic and economic growth, requires very complex ways treatment, where world concern is focused on substitution synthetic products commonly used for depollution by other natural elements, ensure sustainable development. Moreover main object our study exploit supports, as bio polymers able substitute aids flocculation in treatment waters loaded w...

Natural fractures and discontinuities have significant impact on subsurface flow conditions thus production, of carbonate reservoirs, particularly in low-permeability sediments such as chalk-marl successions characterizing the Lower Cretaceous reservoirs Danish North Sea. Yet diversity distribution are often poorly understood largely underestimated. In heterogeneous, tight natural can enhance p...

Abstract Understanding basic petrophysical properties may enhance the recovery of residual oil saturation and help in reservoir management. Reservoir is fraction porosity a zone occupied by oil. The trapping increase with porosity. Oil reservoirs represent significant world-wide. We try to make evaluation using analysis well logs core samples at Issaran Field, South Gharib Formation, West Gulf ...
