Abstract Arbuscular Mycorrhizal Fungi that colonize the roots of plants growing on lands contaminated by heavy metals may influence phytostabilization process reducing translocation to aboveground parts plant. This study aimed evaluate effects soil amendments (lime and lignite) concentration bioavailable form (CaCl 2 extraction) in colonization Lolium perenne when cultivated soil. During experi...

The experimental facility for pressure hydrogasification research was adapted to the pressure of 10 MPa and temperature of 1300 K, which ensured repeatability of results and hydrogen heating to the process temperature. A hydrogasification reaction of chars produced from two rank coals was investigated at temperatures up to 1173 K, pressures up to 8 MPa, and the gas flow rates of 0.5-5 dm(n)(3)/...

To explore increased risk for human Rickettsia spp. infection in Germany, we investigated recreational areas and renatured brown coal surface-mining sites (also used for recreation) for the presence of spotted fever group rickettsiae in ticks. R. raoultii (56.7%), R. slovaca (13.3%), and R. helvetica (>13.4%) were detected in the respective tick species.

In January 2012, the Sierra Club and the Kosovo Institute for Development Policy (INDEP) issued a report entitled Re-evaluating Kosovo’s Least Cost Electricity Option (Sierra Club/INDEP Report). 1 This report evaluated the World Bank’s proposed Kosovo Power Project, as described in the Bank’s December 2011 study, Development and Evaluation of Power Supply Options for Kosovo: A Background Paper ...

Abstract The purpose of this study is to determine the groundwater quality Gadilam River basin on basis Geographic Information Technology (GIS) taxonomy evaluation and risk assessment statistical analysis. originates from district Kallakurichi flows into Viluppuram finally confluence at Bay Bengal in Cuddalore. Groundwater supplies are serving entire drinking needs residents basin, pollution it...

A diode laser based in situ absorption spectrometer is presented for the simultaneous detection of CO (1560nm), water (813nm) and the gas temperature within the combustion chamber of a 600MW lignite-fired power-plant. A fractional absorption resolution better than 10 equivalent to a few hundred ppmV CO could be demonstrated with a 30 sec time response. ? 2000 Optical Society of America OCIS cod...

The modification experiment of Inner Mongolia Baiyinhua lignite by hot air at 200 ℃ for 1 h was carried out. Thestructural changes before and after thermal were analyzed infrared spectrum. Theresults show that the moisture oxygen content in are greatly reduced modification, carboncontent calorific value also increased to varying degrees. In process variousoxygen-containing functional groups dif...

A new acidophilic iron-oxidizing strain (C25) belonging to the novel genus Acidithrix was isolated from pelagic iron-rich aggregates ('iron snow') collected below the redoxcline of an acidic lignite mine lake. Strain C25 catalysed the oxidation of ferrous iron [Fe(II)] under oxic conditions at 25 °C at a rate of 3.8 mM Fe(II) day(-1) in synthetic medium and 3.0 mM Fe(II) day(-1) in sterilized l...

A main objective of restoration and afforestation at post-mining sites is establishing a long-term sustainable ecosystem which depends on adaptations of tree species and which in turn depends on the soil nutrient flux. The nutrient concentration (nitrogen (N), P, K, Ca, Mg, and sulfur (S)) of Scots pine needles was investigated in reclaimed mine soils (RMS) located at the following post-mining ...
