Modeling on adsorption–desorption of trace metals to suspended particle matter in the Changjiang EstuarySpringer Science and Business Media LLC - Tập 53 - Trang 1751-1766 - 2007
Y. Y. Zhang, E. R. Zhang, J. Zhang
The uptake and release of trace metals (Cu, Ni, Zn, Cd, and Co) in estuaries are studied using river and sea end-member waters and suspended particulate matter (SPM) collected from the Changjiang Estuary, China. The kinetics of adsorption and desorption were studied in terms of environmental factors (pH, SPM loading, and salinity) and metal concentrations. The uptake of the metals studied onto SPM...... hiện toàn bộ
Microscopic modelling of the hydraulic fracturing processSpringer Science and Business Media LLC - Tập 68 - Trang 1169-1186 - 2012
Kenneth I. Eshiet, Yong Sheng, Jianqiao Ye
A microscopic perspective is introduced in this study which offers a detailed insight at the inter-particle level to the geo-mechanical responses caused by fluid injection and the resulting pressure build-up. This was achieved by employing the Discrete Element Method (DEM) to model the pressure development and the subsequent fracturing and/or cavity propagation. This technique represents the forma...... hiện toàn bộ
Conceptual site models for sinkhole formation and remediationSpringer Science and Business Media LLC - Tập 76 - Trang 1-12 - 2017
Wanfang Zhou, Mingtang Lei
Extensive research has been done on investigation, monitoring, risk evaluation and land management to prevent formation of sinkholes and subsidences in karst terranes. Little emphasis is, however, given to the various processes and methodologies with respect to their remediation. Sinkholes are a surface symptom of complicated erosion and deformation processes that occur on the surface and in the s...... hiện toàn bộ
Nitrogen and phosphate adsorption on biofilms in reclaimed waterSpringer Science and Business Media LLC - Tập 74 - Trang 451-461 - 2015
Zigong Ning, Mingchao Liang, Zhenhua Wang, Yunkai Li, Yaoze Liu, Tianzhi Wang
Biofilms, abundantly attached on the surfaces of multiple media (such as pebbles and aquatic plants) in rivers or lakes reusing reclaimed water (RW), are of great significance to contaminants’ self-purification of water bodies. In this paper, the nitrogen and phosphate adsorption characteristics of such biofilms were studied by the batch method, using biofilms cultivated under an outdoor simulativ...... hiện toàn bộ
Vulnerability assessment of urban groundwater resources to nitrate: the case study of Mashhad, IranSpringer Science and Business Media LLC - Tập 76 - Trang 1-15 - 2016
Parisa Asadi, Behzad Ataie-Ashtiani, Aliasghar Beheshti
Groundwater vulnerability assessment of urban areas is a challenging task in the fast trend of urbanization around the globe. This study introduces a new approach for modifying well-known parameters of common vulnerability indexes to adjust them for urban areas. The approach is independent of a specific weighting system. The aquifer of Mashhad city, contaminated by domestic wastewater, is selected...... hiện toàn bộ
An introduction to Chinese safety regulations for blasting vibrationSpringer Science and Business Media LLC - Tập 67 - Trang 1951-1959 - 2012
Wen-bo Lu, Yi Luo, Ming Chen, Da-qiang Shu
By reviewing the development history and the state-of-art, this paper introduces Chinese safety regulations for blasting vibration for adjacent structures and equipments, as well as for structures themselves under blasting operation, such as high rock slopes, underground caverns, foundation rock masses, and fresh concrete. The mechanism of failures or damages induced by blasting vibration, the ana...... hiện toàn bộ
