As over 80% of global trade relies on maritime transport, and container shipping accounts for more than 90% of the total value of maritime trade. The research on collusion strategies in a monitored container transport chain based on a tripartite evolutionary game, which this paper tackles, is a very...

ABSTRACT This study evaluated the performance of a high‐resolution statistical downscaling (HSD) approach integrating optimal global climate models (GCMs) and quantile delta mapping (QDM) for the source region of the Yangtze and Yellow rivers, and then projected regional precipitation extremes. The...

The recent status of arsenic pollution in the sediments of the Grand Canal and the West Lake was evaluated. The sorption characteristics of arsenic by the sediments, and the various arsenic species in the sediments were studied.

Recent research progresses in copper pollution of soil-plant system, including the response of soil ecosystem, copper behavior in the soil and bioremediation (especially phytoremediation) of copper-contaminated soil are reviewed in this paper. Some future prospects in this field of research are also...

The present study evaluated the effects of nitrogen nutrition on dry matter and N partitioning in hybrid rice 518. Higher N application significantly increased dry matter partitioning of leaf at the vegetative stage. Partitioning of dry matter to leaves decreased as the N concentration in the leaves...

The accumulation mechanism of Cd and Pb in raddish roots was studied. The results showed that in the first 12 hours the accumulation process of Pb in roots was probably due to rapid adsorption, later, to slow chemical precipitation and cell absorption. Especially, at high Pb content, chemical precip...

The present paper deals with the chemical behavior of Pb, Cd and their interaction in rhizosphere and bulk after growing plants (rice or wheat) using a rhizobox or rhizobag. The main results were as follows: The contents of Pb extractable in both rice and wheat rhizosphere of the red soils, were hig...

Simple analysis methods using microwave and boiling waterbath to solve the problem for microcystin-LR (MCLR) and microcystin-RR (MCRR) extraction from cyanobacteria cells were studied as a substitute for the traditional solvent extraction methods. Standards were used to confirm the feasibility and e...

Four different amounts of inoculum in mixed sludge, namely 2%, 5%, 10% and 20%, were adopted to investigate the bioleaching of heavy metals from sludge by batch experiment. The result showed that the rate and degree of decrease in pH increased with the amount of inoculum at the beginning. The pH of...

Contract farming has been increasingly found to benefit smallholders in developing countries, yet much less is known about its role in the poultry industry where economies of scale could be more prominent. This study aims to narrow this gap by analysing the choice of contract farming among Chinese b...
