The mechanism of the fluid-solid coupled vibration is analyzed as the fluctuating pressure acts on the inlet and the outlet slits of a slab. The parameter multinomial method was exploited to calculate the pressure field within the joints of the slabs by solving the basic equations of the oscillation flow. The calculated result shows that the time-averaged uplift increases with the increase of the length of the slab and is large in the middle and is small in both sides. The time-averaged uplift reduces with the increase of water depth, and the fluctuating uplift reduces rapidly with the increase of the thickness of the slit. The calculated result is in agreement with the experimental results.

Spent selective catalytic reduction(SCR) catalysts are defined as hazardous wastes because of the toxicity of V2O5to the ecological environment. Recycling of V2O5and TiO2from the spent SCR catalysts has strikingly social and environmental benefits as well as economic values. In this work, a “NaOH + Na2CO3” system was employed to recycle 99.2% of anatase/rutile TiO2nanospheres with a nanospherical morphology from the spent SCR catalysts by a simple sintering-leaching process. The observed photocatalytic performance of anatase/rutile TiO2nanospheres was higher than that of the other TiO2recovered from the spent SCR catalysts,commercial TiO2, and chemosynthetic TiO2, which can be ascribed to the enhanced separation of photo-excited electron/hole in a direct Z-scheme of anatase/rutile TiO2homostructures. Additionally, high-purity V2O5microrods with high H2S removal performance were efficiently prepared by a hydrothermal method in the leaching solution, which is superior to the traditional method including NH4VO3precipitation and solvent extraction as the present method can recycle vanadate from low-grade filtrate with a 99.6% of recovery *** study develops an alternative method for controlling pollution of vanadate to soil and water and recycling of valuable metals.

The Z curve is a very useful method for visual-izing and analyzing DNA sequences. It is a three-dimensional space curve that constitutes a unique representation of a given DNA se-quence. It becomes more and more important to study non-coding regions in the recent years. Using Z curve method, 15 disease-related ncRNAs and some snoRNAs and miRNAs sequences are selected from the NONCODE database in this paper, which relate to Alzheimer Disease. The corresponding Z curves of the studied ncRNAs, sequences have been mapped and compared. The statistical features of the Z curves are ob-tained. These features indicate that the ncRNAs sequences playing same roles in the celluar process have almost the same Z-curves. And the base content in these sequences is almost same too.
