Wings of various Drosophila melanogaster fly lines were analyzed: the common laboratory fly strain OregonR, inbred fly strains North-Carolina 375 and North-Carolina 399, and wild-caught flies from New Jersey, USA and Cartagena, Colombia. Flies were grown at 22◦C, except otherwise noted. For the temperature experiment, flies were kept at defined temperatures (16◦C, 18◦C, and 28◦C) for two genera...

While it is true that fly ash contains trace amounts of certain elements, which can be toxic in larger concentrations, it is unlikely that fly ash as used in concrete would exhibit leaching characteristics. First, the permeability of concrete containing fly ash is negligible compared to the permeability of fly ash as typically disposed. This reduced permeability prevents water or other liquids ...

Studies were performed to compare the physical and chemical characteristics and the in vitro macrophage cytotoxicity of oil and coal fly ash. Sampling methodology was developed to collect size-fractionated particulate matter from the smokestack of either a coal-fired or an oil-fired power plant. Morphological studies demonstrated particle heterogeneity, although most coal fly ash particles appe...

In this study, the treatment of fly ash and steel making slag in aqueous ammonia chloride has been conducted. These zero-value wastes have distinctively high concentrations of magnesium, calcium and iron. The ammonium chloride has been employed as the leaching reagent to extract MgO out of fly ash and slag, and the dissolved cations in the leachate were subsequently precipitated by carbonation....

In order to study the application of lime-fly ash loess in permafrost subgrade engineering, uniaxial compressive test, fast direct shearing test and permeability tests were carried out on lime-fly ash loess under different curing ages and freeze-thaw cycles. Uniaxial compressive strength of lime-fly ash loess increases slowly with the curing ages, and can reach 3.5 Mpa after the curing ages of ...

In this paper, the design of a real-time image acquisition system for tracking the movement of Drosophila in three-dimensional space is presented. The system uses three calibrated and synchronized cameras to detect multiple flies and integrates the detected fly silhouettes to construct the three-dimensional visual hull models of each fly. We used an extended Kalman filter to estimate the state ...

Emami Paper Mill Ltd. at Balgopalpur industrial area produces a huge amount of fly ash and waste water to the environment. The application of disposed fly ash and waste water in crop cultivation may reduce the problem to some extent. The aim of this study is to investigate the effects of direct land application of fly ash on plant growth and production of rice (Oriza sativa). In the fly ash exp...
