The construction industry has played an important role in reducing carbon emissions. Various policies have been implemented to stimulate construction enterprises to reduce carbon emissions, but the effects of emission reduction are not obvious, for they do not directly benefit the enterprises. This paper employs a modified Shapley value method to study benefit allocation in a construction supply chain...
During shortcut biological nitrogen removal in a polluted river, total nitrogen, ammonia nitrogen and nitrite nitrogen were quantified by near infrared spectroscopy and the synergy interval partial least squares (siPLS) algorithm. Spectral data of 138 water samples were obtained with a near infrared spectrometer. In addition, the real values of total nitrogen, ammonia nitrogen and nitrite nitrogen...
Aspergillus niger is adopted in bioleaching to dispose of sludge from an urban wastewater treatment plant to determine the bioleaching influence of sludge on heavy metal fraction and nutritive material loss. The enrichment effect on wheat seedlings of Cu, Zn, Pb, and Cd in sludge is researched by a soil-cultivated experiment. Results indicate that the removal rates of Cu, Zn, Pb, and Cd are 74.1%,...
As urbanization increases, urban runoff becomes an increasingly more important component of urban non-point pollution. In this study, the Storm Water Management Model was used to simulate the quantity and quality of runoff in a highly urbanized catchment. Data from three rainfall events were collected and used for model calibration and validation. Model performance was assessed using the Nash-Sutcliffe...
To determine the growth rate and element contents of fingernails in young adults, 109 apparently healthy college students were recruited for determination. As a result, the average growth rate of the left thumb was 3.14±0.63 mm/month with significantly faster rates in male and taller participants. The concentrations for Ca, Na, P, K, and Mg were 701.1±274.8 µg/g, 452.3±353.9 µg/g, 33l.6±119.7 µg/g,...
