This study is focused on the emission of fixed bed combustor batch operated. Real-time analyser ELPI (electrical low-pressure impactor) system was used to size-segregated particulate matter emission ranging from 40 nm to 10 μm. The results show that total number concentration were 3.4 × 10(3), 1.6 × 10(4), and 1.5 × 10(5) particles/cm(3) · kg(fuel), while total mass of particles were 12.2, 8.0,...
Standard procedure for dispersing natural soils for particle size fractionation can be too aggressive for soil containing coal and other organic particles from coal industries. We have investigated ultrasonic dispersion for the latter in four soils differing in pedogenesis (Phaeozem, Podzol, reclaimed mine soils), carbon content (27.5±138.6 g kg), clay content (80±153 g kg) and sources of parti...
Although hypersaline environments pose challenges to life because of the low water content (water activity), many such habitats appear to support eukaryotic microbes. This contribution presents brief reviews of our current knowledge on eukaryotes of water-column haloclines and brines from Deep Hypersaline Anoxic Basins (DHABs) of the Eastern Mediterranean, as well as shallow-water hypersaline m...
Microbial life inhabits deeply buried marine sediments, but the extent of this vast ecosystem remains poorly constrained. Here we provide evidence for the existence of microbial communities in ~40° to 60°C sediment associated with lignite coal beds at ~1.5 to 2.5 km below the seafloor in the Pacific Ocean off Japan. Microbial methanogenesis was indicated by the isotopic compositions of methane ...
The geographic origin of bats is still unknown, and fossils of earliest bats are rare and poorly diversified, with, maybe, the exception of Europe. The earliest bats are recorded from the Early Eocene of North America, Europe, North Africa and Australia where they seem to appear suddenly and simultaneously. Until now, the oldest record in Asia was from theMiddle Eocene. In this paper, we report...
Flooding the remaining gaps of lignite open-pits and formation so-called open-pit lakes tends to become an increasingly common practice in Romania (in Oltenia Mining Basin, where deposit contained Dacian Romanian formations was is extracted through open-pits). This type ecological reconstruction former exploitation areas has been applied worldwide for quite a time, there are many references thi...
Apart from the history and traditions associated with this material, there are several questions that need to be answered. What exactly is Spanish jet? What is its nature? What are the reasons for its special properties and, above all, why has it retained its reputation over so many years as an unalterable material throughout time? Spanish jet is a humic coal, conventionally assimilated to a va...
