Anaerobic digestion can be used to convert organic waste into energy not only to provide renewable energy, but also reduce greenhouse gases. During the anaerobic digestion process, biogas is produced, which can be used for heating and electricity generation. The produced biogas contains methane and some other gases, the most destructive of which is hydrogen sulfide gas. If hydrogen sulfide gas ...
Portland cement could be produced by heating the raw materials (clay, lime stone) about 1500°C which clinker will be formed. The geochemistry and mineralogical studies of raw materials, clinker, Portland cement and dust have been carried out by optical microscopy, X-ray diffraction and X-ray florescence. The results of spectrometry indicate the presence of calcite mineral in limestone, montmori...
Hyperspectral imaging is a powerful tool for mineral mapping and increasingly used in poorly-accessible areas. It only requires a limited amount of validation sample points, but can fail to discriminate spectrally-similar features. In this manuscript, we show that we improve the identification of interesting targets by including geomorphological data in the spectral mapping scheme. We jointly u...
Regional tectonic synthesis suggests that a segment of the bipartite eastern Gondwana-type Carpathian-Balkan nappe-stacked Getic/Kučaj/Supragetic basement (eastern Serbia) experienced Cambro-Ordovician Cenerian (Sardic) accretionary-type deformation. The Ordovician Alpine Getic/Kučaj nappe exposes an earlier-mapped shallow-marine transgressive-type Fe-silicate-rich ironstone sequence. is used a...
CO 2 geological storage will be needed as part of the transition to lower greenhouse gas emissions. During storage, mobilization metals from minerals formation water via rock reactions may a concern for quality. The sources, behavior, and fate metals, however, are not well understood. Metals in calcite cemented sandstone, feldspar-rich ironstone seal drill cores target site were characterized. ...
The return of vegetation to mined lands often requires broadcast seeding diverse native seed mixes. However, seeds are highly adapted germination windows with specific hydrothermal thresholds that maximize the likelihood seedling survival, and post-mining landscapes typically offer markedly different conditions than pre-disturbance ecosystems. According niche theory, generalist species should e...
Palynological study of Tungu Buzum Hill was investigated with a view towards determining the age outcrop, compare its miospore content adjacent Buzu Valley carbonaceous shale, their stratigraphic relationship and paleoenvironment deposition litho-sequence. Field involved litho-description logging achieved by noting rock type, mineralogical composition, bed thickness, texture, sorting, roundness...
Purpose . Barsova Gora is a unique archaeological and landscape site located in the Tyumen Region (West Siberia) of Russian Federation. The technical technological analysis Kalinkino ceramics from Barsov gorodok III/2 settlement (25 vessels) was performed accordance with method developed by A. Bobrinsky. Results For manufacture vessels at settlement, ferruginous clays were selected. Five subspe...
The impact of discharges from abandoned metal and ironstone mines has been a much studied form of aquatic pollution in recent decades. Few attempts however, have been made to accurately determine the overall contaminant mass flux arising from abandoned mine sites at scales above catchment level. Such assessments are critical to determine the significance of former mining to national, regional a...
Ceramics marked with the Phillips name are frequently found in estate auctions, antiques shops, and historical societies in New England. While transfer printed wares predominate, the firm produced a range of earthenwares, including flow blue, creamware, edged ware, painted pearlware, plain white ironstone, and luster. Printed pieces were often marked with a transfer containing the name of the p...
