Impact of Zn–Pb mining in the Olkusz ore district on the Permian aquifer (SW Poland)
Long-term extensive mining of Zn-Pb ores in the Olkusz area resulted in significant changes of water table levels and chemical composition of water in all aquifers in this area. Within the Permian aquifer, hydrochemical type of water evolved in two general stages. Short-term effect was freshening in the zones of contact with overlying the Triassic limestones and dolomites. Long-term effect was ...

15 صفحه اولOn the Importance of Header Classification in HW/SW Network Intrusion Detection Systems
In this paper we examine the impact of various levels of (partial) hardware acceleration levels on a software based Network Intrusion Detection System. While complete hardware solutions are possible and have been studied extensively, they are costly and may suffer from scalability and flexibility limitations. The flexibility of software is attractive to address these concerns. We show in this p...
متن کاملMethane Release from Igneous Intrusion of Coal during Late Permian Extinction Events
Unusually large and locally variable carbon isotope excursions coincident with mass extinctions at the end of the Permian Period (253 Ma) and Guadalupian Epoch (260 Ma) can be attributed to methane outbursts to the atmosphere. Methane has isotopic values (dC) low enough to reduce to feasible amounts the carbon required for isotopic mass balance. The duration of the carbon isotopic excursions an...
