This paper presents a numerical analysis of the mechanical performance bentonite clay buffer for containment nuclear waste in context deep geological disposal. The design is based on Swiss concept where canisters are emplaced pedestals compacted blocks and remaining space between tunnel canister backfilled with grains highly bentonite. A complete long-term repository requires good understanding...

Several types of fundamental ontological relations connect the endurant (continuant) and perdurant (occurrent) entities in every domain. These include: instantiation, parthood, location, and connection relations, and those that are derived from them, such as adjacency, overlap, containment, and coincidence. Some of these types of relations, and their subtypes, are formally defi ned in the conte...

The history of geological cartography the present territory Lithuania starts with a map published by Jean Etienne Guettard in 1764 and followed maps Stanisław Staszic 1806, Ignacy Domeyko 1837, Frederic Dubois de Montpereaux 1830. A new period investigations compilation about 1840 is closely related development stratigraphic knowledge; therefore, this marks beginning mapping using concept (Helm...

The Neoproterozoic era was arguably the most revolutionary in Earth history. Extending from 1000 to 541 million years ago, it stands at the intersection of the two great tracts of evolutionary time: on the one side, some three billion years of pervasively microbial 'Precambrian' life, and on the other the modern 'Phanerozoic' biosphere with its extraordinary diversity of large multicellular org...

Projections of climate change impact are associated with a cascade of uncertainties including in CO2 emission scenarios, climate models, downscaling and impact models. The relative importance of the individual uncertainty sources is expected to depend on several factors including the quantity that is projected. In the present study the impacts of climate model uncertainty and geological model u...

The Mar Piccolo basin is an internal sea basin located along the Ionian coast (Southern Italy), and it is surrounded primarily by fractured carbonate karstic environment. Because of the karstic features, the main continental water inflow is from groundwater discharge. The Mar Piccolo basin represents a peculiar and sensitive environment and a social emergency because of sea water and sediment p...

saymareh dam and hydro-power plant are under construction on saymareh river in ravandi anticline, ilam province. during boring the power tunnel which crosses the anticline, a large volume of water was encountered. this volume of water was not observed in the past. considering the water quality of springs, water level of dam site piezometers, geological and hydrogeological inspections, isotope a...
