All rights reserved.The main objectives of this study are determining grey and blue water footprints and identifying the hotspots of the carbon in pulp (CIP) gold processing using water footprint assessment (WFA). Results revealed that the total blue water footprint, including the extraction and processing of the gold, was found 452.40 m3/kg Au, and the grey WF 2300.69 m3/kg Au. On the direct blue WF side the lost return flow has the largest contribution, with a value of 260.61 m3/kg Au, and the only source of the lost return flow is the tailing pond. On the indirect side, it is seen that the oxygen consumption used for the leaching process has the highest value, with 37.38 m3/kg. For the grey water footprint, the critical component is by far arsenic among the nine contaminants in the mine tailings, with a value of 1777 m3/kg Au. The results will be used to make recommendations for reducing water consumption in mining operations and to develop sustainable design for environment. The study is a pioneering study, being the first implementation of water footprint assessment in gold mining in Turkey.

© 2022 Gazi Universitesi Muhendislik-Mimarlik. All rights reserved.In this paper, a shear deformable force-based frame finite element with semi-rigid connections is derived for nonlinear analysis of steel structures. Distributed plasticity approach is defined along element length and section depth, and linear or non-linear semi-rigid connection behavior can be specified anywhere along elements without the necessity to define additional nodes and to increase the degrees of freedom of the structural system.

© 2022. L&H Scientific Publishing, LLC. All Rights Reserved.The impulsive differential equations with unpredictable perturbations are under investigation. The definition of the discontinuous unpredictable function with the discrete unpredictable set of discontinuity moments is introduced. The existence and uniqueness of asymptotically stable discontinuous unpredictable solutions for quasi linear systems are proved. Examples with simulations are given to illustrate the results.

All Rights Reserved.Lignocellulolytic enzymes such as cellulases and xylanases are needed on the industrial scales for low cost production of biofuels and the other value-added products from lignocellulosic biomass such as distillers' dried grains with solubles (DDGS). Optimization of fermentation variables such as agitation, aeration, and inoculum size for fungal enzyme production by submerged fermentation can enhance the enzyme production levels. Therefore, this research focuses on the stati...
