In this research, Ningbo City, a typical industrial city in southeastern China, was selected as the study area, and concentrations of 12 heavy metals (Cd, Cr, Ni, Pb, Zn, Cu, Hg, As, Co, V, Se, Mn) were measured at 248 sampling points. Pollution index methods used to assess status soil metal contamination, Positive Matrix Factorization (PMF) model Unmix integrated identify apportion sources contamination. The results indicated that nearly 70% area polluted by metals, Zn main enriched metals....

As a new type of bridge foundation, rectangular closed diaphragm walls (RCDWs) provide an efficient solution to controlling the settlement high-speed railway bridges. However, scant research on prediction for RCDWs has hindered their application in practical engineering. This paper attempts establish simplified approach predicting RCDWs. First, analytical model RCDW is established accordance with load transfer approach. Then, curves and related coefficients skin friction foot resistance are...

Perishable goods are those whose value decay rapidly over time. To reach the maximum profit, vendors should sell them as soon possible ever since they available on market. Advance selling strategy refers to a product before it is ready for sale and this helps sellers observe market response adjust its operational plans. With rapid development of E-commerce, becomes much easier cheaper both buyers search desired information. has become an effective popular sales perishable selling. In paper,...
