On the Weldability of Thick P355NL1 Pressure Vessel Steel Plates Using Laser Welding.

Pipeline transport uses millions of kilometers of pipes worldwide to transport liquid or gas over long distances to the point of consumption. High demands are placed, especially on the transport of hazardous substances under high pressure (gas, oil, etc.).

Assessment of elemental distribution and trace element contamination in surficial wetland sediments, Southern Tibetan Plateau.

An investigation was performed to measure concentrations of major and trace elements in surficial wetland sediments in the southern Tibetan Plateau in order to assess the sediment quality. Results showed that most of elements have concentrations comparable to those of the Tibetan surface soil (TSS) except for As, Ca, Cs, Sr, and Cu. Correlation analysis indicated that most elements were highly associated with major crustal elements, suggestive of their common natural origin.
