Emerald ash borer (Agrilus planipennis Fairmaire) is an invasive primary pest of North American ash (Fraxinus spp.) trees. Blue ash (F. quadrangulata) is less susceptible to emerald ash borer infestations in the forest than other species of North American ash. Whereas other studies have examined adult host preferences, we compared the capacity of emerald ash borer larvae reared from emerald ash...

The recovery of phosphorus (P) from sewage sludge ashes has been the focus recent research due to initiatives for use biogenic resources and resource recovery. This study investigates ash transformation chemistry P in during co-gasification with K-Si- K-rich agricultural residues wheat straw sunflower husks, respectively, at temperatures relevant fluidized bed technology, namely 800 °C 950 °C. ...

Abstract Fly ash as residue from coal combustion has potential for environmental applications an adsorbent water pollution treatment. Adsorption performance of fly depends on origin and chemical Modification by the treatment could increase adsorption capacity. In this paper, was alkali modified with NaOH solution at various concentrations (2 N, 4 6 10 N) a temperature 60 °C. The physical proper...

Leaching of fluoride from fly ash has been studied at different ash/water ratios and temperatures and also over a broad range of pH. The efficiency of leaching was only slightly dependent on the ash/water ratio, thus revealing a solubilitycontrolled mechanism of the process. The efficiency was also independent of the temperature over the range 20 90°C.

Most applications of coal fly ash, such as concrete, structural fill, and waste stabilization, use fresh fly ash received directly from coal fired power generation plants. However, if the current rate of usage continues, the demand for fresh coal fly ash for various applications will increase and utilization of coal fly ash disposed in landfills will have to be considered. This study investigat...

A preliminary in vitro acid neutralizing capacity test of twelve traditional Ayurvedic antacids were performed in this study. Five traditional preparations of ash of conch shell, ash of oyster, ash of pearl, limestone, and ash of cowrie showed high acid neutralizing capacity similar to standard antacid combination of Al(OH) 3 and Mg(OH) 2 . Among these the ash of conch shell found the highest a...

This research explores the influence of fly ash source, alkali concentration and temperature on dissolution kinetics Al Si. The characteristics reaction products solid residue were evaluated with ICP-MS, SEM-EDS, quantitative XRD. It was found that occurs faster a higher yield compared to Si for both types. NaOH had similar effect Al, while influenced more by concentration. simultaneous alumino...
