Abstract The Western Balkans hosts the richest subterranean aquatic gastropod fauna in world. main factors shaping intraspecies diversity are thought to be isolation and endemism. In genus Belgrandiella , minute snails inhabiting waters springs Central Europe Balkans, molecular studies have shown much fewer valid species than previously anticipated. present study applies mitochondrial cytochrom...

of the Dalmatian coast type, formed primarily from karst limestone, Eastern Adriatic coast shows great diversity of habitats. This diversity is also influenced by the position of the Adriatic Basin, stretching from northwest to southeast, climatic differences along its length, and the direction of sea currents. Habitats in the submerged karst characteristic for the Croatian side of the Adriatic...

The mid-Cretaceous histories (origin, growth, death) of algal-rudist-stromatoporoid reef communities located on many Pacific Basin guyots are complex and controversial. These shallow water, tropical communities originated on volcanic edifices extruded during the Barremian-Albian, grew upward during edifice subsidenceftransgression throughout the Aptian, Albian and Cenomanian and several of them...

Abstract Although chalk aquifers are not too often associated with conduit flow, they highly productive groundwater systems and, like limestone aquifers, can be vulnerable to contamination when exposed land use activities. The Danish carbonate rocks generally recognized fractured and covered by thick Quaternary sediments. Fissure flow is pronounced, occurring in the upper 50–100 m due Pleistoce...

In a mature karstic system, the realisation of galleries using the methodology of railway tunnel boring machine (TBM) involves particular problems due to the high risk of interference with groundwater (often subject to remarkable level variations) and with cavities and/or thick fill deposits. In order to define groundwater features it is necessary to investigate both hydrodynamic and karstifica...

In this article, the temporal and spatial development of probable sinkholes in close vicinity a couple that occurred 2007 2018 Kozaklı (Nevşehir) geothermal field, which is one most important thermal tourism centers where treatment with radon gases mud can be carried out Central Anatolia, was investigated using multi-electrode resistivity method core drilling data. The primary water aquifer con...

Abstract Faults and fractures are a critical store pathway for groundwater in Ireland’s limestone bedrock aquifers either directly as conductive structures or indirectly the locus development of karst conduits. From quantitative analysis post-Devonian faults range lithological sequences, this report describes principal characteristics Cenozoic strike-slip joints, youngest most intrinsically wit...

An empirical potential energy surface has been developed for the Ne·OH/D complexes from the experimentally observed vibrational and rotational energy levels with ab initio calculations being used for initial esti-

Abstract. The Franconian Alb of SE Germany is characterized by large-scale exposures Jurassic shallow marine limestones and dolostones, which are frequently considered to be outcrop analogues for deep geothermal reservoir rocks in the North Alpine Foreland Basin farther south. However, burial history strata not well known as they were affected emersion, leading extensive erosion karstification ...

to investigate the electromagnetic interaction of molecules inside the nanotubes, first, the structure of nanotubes b16n16 was optimized with hybrid density functional theory (b3lyp) using the epr-ii basis set, then cu, cu+, cu++ were located in nanotube and we studied the total energy, band gap energy, electrical potential, changes of band gap energy in terms of total energy and dipole moment ...
