Comprehensive Network Analysis Identified SIRT7, NTRK2, and CHI3L1 as New Potential Markers for Intervertebral Disc Degeneration.

Intervertebral disc degeneration (IDD) is considered the basis of serious clinical symptoms, especially for low back pain (LBP). Therefore, it is essential to explore the regulatory role and diagnostic performance of dysregulated genes and potential drugs in IDD. Through WGCNA co-expression analysis, 36 co-expression modules were obtained.

Formation of bcc and fcc during the coalescence of free and supported Fe and Ni clusters.

The formation of bcc and fcc during the coalescence of free and supported Fe and Ni clusters has been studied by molecular dynamics simulation using an embedded atom method. Structural evolution of the clusters, coalesced under varying temperature, Ni content and substrate conditions, was explored by interatomic energy, snapshots, pair distribution functions and bond order parameters. The results show that the formation of bcc and fcc is strongly related to Ni content, substrate and coalescence temperature.

Evolution of morphology in electrodeposited nanocrystalline Co-Ni films by in-situ high magnetic field application.

The effect of high magnetic fields up to 12 T, applied during electrodeposition process, on the morphology of nanocrystalline CoNi films has been investigated. The magneto-induced dramatic modifications in the morphology were observed by using field-emission scanning electronic microscopy and atomic force microscopy. Along with the increase of magnetic flux density (B), the grain size and the surface roughness of the films increased to reach a maximum value at a field of 9 T.

[Air pollutant emissions of aircraft in China in recent 30 years].

Although aircrafts are of great importance in transportation in China, there has been rare study on air pollutant emissions of aircrafts until now. Based on the annually statistical data collected by the Statistic Center of Civil Aviation of China, using the emission factor method derived from fuel consumption, the air pollutant emissions of aircrafts during 1980-2009 were calculated, and their emission intensities and dynamic characteristics were analyzed. The results show that the emissions of SO2, CO, NO(x) and HC from aircrafts of China Civil Aviation increased from 0.

[Air pollutants emissions of locomotives in China railways in recent 33 years].

Although railway has played a great role in transportation in China, there has been no any study on air pollutants emissions of locomotives until now. Based on the annual statistical data collected by the Chinese Railway Statistic Center, using the emission factor method derived from fuel consumption, the air pollutants emissions of locomotives during 1975-2007 were calculated, and their emission intensities and dynamic characteristics were analyzed. The results show that the emissions of soot, SO2, CO and CnHm from steam and diesel locomotives in china decreased from 3510.

Effects of high magnetic fields on solidified structures of Mn-90.4 wt% Sb hypoeutectic alloy.

Mn-90.4 wt% Sb alloy specimens were solidified under both uniform magnetic field and magnetic field gradient conditions. The solidification behavior was examined to elucidate the effects of high magnetic fields on the solidified structure evolution of this hypoeutectic alloy.
