Coal and lignite regions are on the way to reinvent themselves. In this work, three aspects related reclamation exploitation of these mining areas analyzed, focusing role geotechnical engineering. Firstly, slope stability excavations is examined during water filling practice. Secondly, effect extreme rainfall studied abandoned mines. Finally, potential a waste dump by highway or railroad invest...

The coal mining residues from past activities in the Douro Coalfield are emplaced many dumps near areas, causing substantial environmental impacts. This study aims to contribute investigation of impacts caused by disposal residue through determination geochemical composition waste materials collected at 3 – 15 m depth, and water-leachable fraction produced percolation these inside dump. element...

Experimental evidence for a 5-exocyclic methylene-dUMP intermediate in the thymidylate synthase reaction was recently obtained by demonstrating that tryptophan 82 mutants of the Lactobacillus casei enzyme produced 5-(2-hydroxyethyl)thiomethyl-dUMP (HETM-dUMP) (Barret, J. E., Maltby, D. A., Santi, D. V., and Schultz, P. G. (1998) J. Am. Chem. Soc. 120, 449-450). The unusual product was proposed ...

An industrial waste-phosphogypsum-is formed in the production of phosphorus mineral fertilizers. As is well-known, issues processing and utilization phosphogypsum on an scale remain unsolved. Consequently, waste generated at chemical plants stored various types storage tanks. The currently used hydraulic method provides for supply form a slurry into dump cells, their sequential dehydration dump...

Initial commissioning of the LHC beam dump system with beam took place in August and September 2008. The preparation, setting-up and the tests performed are described together with results of the extractions of beam into the dump lines. Analysis of the first detailed aperture measurements of the extraction channels and kicker performance derived from dilution sweep shapes are presented. The per...

Sewage sludge dumped at Garroch Head in the Firth of Clyde contains significant quantities of chlorinated hydrocarbons, such as polychlorinated biphenyls (CBs). These compounds are lipophilic and resistant to degradation. They accumulate in the biota either from the water column or through the food chain, particularly in tissue with a high lipid content. Bottom dwelling fish, such as plaice, in...

Homo Electromagneticus is a musical performance realized in 2022 through set of original instruments created with open-source and low-cost technologies. Arduino microcontrollers, sensors, brainwaves, MIDI, algorithms, the interaction plants’ capacitance provide digital, acoustic mechatronic sound production forms. Cognizant material energy dump that signature Anthropocene, piece thrives on comm...

During a period of 60 days assays were carried out with the moss Pohlia nutans transplanted from an uncontaminated control site to a dump consisting of a heavily polluted mine and smelter wastes located near wałbrzych in southwestern Poland. within the same period also samples of native P. nutans growing on the dump substrate were collected together with the same species from a control site. Co...
