The invasive emerald ash borer (EAB, Agrilus planipennis Fairmaire) infects and eventually kills endemic ash trees and is currently spreading across the Great Lakes region of North America. The need for early detection of EAB infestation is critical to managing the spread of this pest. Using WorldView-2 (WV2) imagery, the goal of this study was to establish a remote sensing-based method for map...

Fly ash particles emitted from municipal solid waste-incinerators are of environmental concern. This study aims to investigate the applicability of sedimentation/steric field-flow fractionation (Sd/StFFF) and to develop a Sd/StFFF method for the separation and size characterization of incinerator fly ash. This study focuses on the fly ash particles larger than approxiamtely 1 microm, which comp...

Woody biomass is an abundant, renewable energy source. Forest residue is the fraction remaining after harvest and the outtake of wood timber, including tree tops and bark. Compared with the wood portion, bark has a wide variation of ash content. Wood usually has a relatively low ash content, while bark has considerably higher ash content, which may generate clinker in the furnace and thereby te...

Fly ash is an important waste, produced in thermal power plants which causes very important environmental pollutions. For this reason the usage and evaluation the fly ash in various areas are very important. Nearly, 15 million tons/year of fly ash is produced in Turkey. In this study, usage of fly ash with diatomite and molasses for heavy metal (Cd) adsorption from wastewater is investigated. T...

Fly ash is a waste produced mostly from the burning of coal in thermal power stations, which contributes to environmental pollution. Also, a number of studies have been conducted to investigate the influence of randomly oriented fibers on the engineering behavior of coarse grained and fine grained soils. The influence of randomly oriented polypropylene fibers on the engineering behavior of soil...

Expansive soil is collected near the mirchi yard gutur district, where NH 5 expansion is taking place. This study revealed that the fiber reinforcement improves the CBR values in admixture stabilized soil. In the present work, an attempt is made to compare the quantity of the earth required for the sub grade with and without fly ash stabilization, for 1.5% of fiber and 15 % of fly ash the thick...

Airborne volcanic ash particles are a known hazard to aviation. Currently, there are no means available to detect ash in flight as the particles are too fine (radii < 30 μm) for on-board radar detection and, even in good visibility, ash clouds are difficult or impossible to detect by eye. The economic cost and societal impact of the April/May 2010 Icelandic eruption of Eyjafjallajökull generate...

Effective survey methods to detect and monitor recently established, low-density infestations of emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), remain a high priority because they provide land managers and property owners with time to implement tactics to slow emerald ash borer population growth and the progression of ash mortality. We evaluated options for using gi...

in this study, the chemical characterization of solid residues, i.e., bottom ash, fly ash, and filter cake, produced from the izmit hazardous and Clinical waste incineration Plant (izAyDAS) was investigated. the izAyDAS is located in the city of kocaeli in turkey and it has been in use since 1997. Several parameters were measured, including AoX, Cl-, CN-, So4 2and selected heavy metals includin...
