The abiotic environment often influences the ways in which animals interact. By affecting the cues associated with buried seeds, the type of substrate used by seed-caching rodents may alter the relative probabilities of cache pilferage and cache retrieval. We predicted that, after a wildfire, the presence of ash would impair rodents’ ability to smell pine seeds on the forest floor. In a laborat...

The potential problems and their consequences due to fly ash disposal have been well studied around the world. Ash pond is a common available disposal facility for thermal power plants. The pond ash is subjected to weathering and the ions present in ash migrate to the soil and subsequently to the ground water over a period of time. A study has been carried out at Vijayawada Thermal Power Statio...

It might not appear at first that this paper has sig­ nificance in the field of Solid Waste Processing, since it applies to cleaning wash water from cleaning the fireside surfaces of utility boilers burning gas and oil. It is generally believed that systems which burn mu­ nicipal solid waste (MSW) do not require treatment of boiler wash water, since this can be used to quench the ash and thus b...

Copper is one of the most important trace elements in municipal solid waste (MSW) combustion. Knowledge of the speciation of copper is fundamental for the understanding of the effects of copper compounds on the combustion chemistry, for the evaluation of the environmental effects of copper in ash leachates and for the development of methods to recover copper from the MSW combustion ash. In this...

Volcanic activity is observed worldwide with a variety of ground and space-based remote sensing instruments, each with advantages and drawbacks. No single system can give a comprehensive description of eruptive activity, and so, a multi-sensor approach is required. This work integrates infrared and microwave volcanic ash retrievals obtained from the geostationary Meteosat Second Generation (MSG...

The behaviour of alkali metals, especially of potassium, during circulating fluidised bed combustion of wood-based fuels was studied experimentally in pilot-scale and industrial scale combustors. The fuels included willow, forest residue and waste wood co-combusted with paper mill sludge. As a result of this work, the main chemical and physical transformation mechanisms of potassium compounds i...

The study of undertaken for heavy metal Pb accumulation by fly ash and coal waste in Singrauli industrialised district of India, using atomic absorption spectrometry. Ashes from collected vegetables and plants leaves samples were analysed for the quality and quantity of Cr, Mn, Pb, Zn, Cu, As, Ni and Co and detectable levels of all were found. Pb distrusted the metabolic processes of living org...

BACKGROUND U.S. military perception of nuclear warfare led to countless unethical nuclear experiments performed on unsuspecting individuals without their informed consent. As evidenced here, subsequent perception of weather warfare has led to exposing millions of unsuspecting individuals to toxic coal fly ash with no public disclosure, no informed consent, and no health warnings. METHODS Thre...

This paper deals with use of pond ash and RBI Grade 81 for improvement in CBR values of clayey soil and grade-III materials used for base course of flexible pavement. The pond ash is a thermal power plant waste and RBI Grade 81 is chemical soil stabilizer. The geotechnical properties like Maximum Dry Density (MDD), Optimum Moisture Content (OMC), Unconfined Compressive Strength (UCS), CBR value...

The effects of wood ash fertilization on soil chemical properties were studied in three young Scots pine (Pinus sylvestris L.) plantations and a Norway spruce (Picea abies (L.) Karst.) plantation with different site fertility in southern Finland. The dose of 3 t ha–1 of loose wood ash was applied to 4 replicate plots (25 × 25 m) at each experiment. Humus layer and mineral soil samples were take...
