During screening operation, blinding or clogging of screen perforations generally occurs to reduce the sieving capacity and efficiency. Recently, the flip-flow screening has been widely recognized as a feasible method to deal with the problem. In this paper, a novel centralized-driving flip-flow screen(CFS) was developed for the separation of fine and moist coal, and the key structures, namely, a centralized-driving mechanism and a quasi-circle beam mounted with the mat were designed for high reliability and stability. By means of a test on an experimental prototype, the effect of some factors, i.e., initial stretch and hardness of the polyurethane panel, respectively, and the rotation speed of the driving motor on the kinematic characteristic of the screen surface was investigated. Results show that without an initial stretch, the sieve mat generates the largest vibratory amplitude while the slacker the sieve mat initially is, the smaller amplitude it will accomplish. And an increase in the rotation speed could cause a rise in the vibratory amplitude. Unlike the two factors, the hardness does not have a definite effect on the kinematic performance, on which a further study is required. Finally, screening processing on a laboratory prototype was conducted to draw the conclusion that the developed CFS also has a high sieving efficiency for the fine and moist coal.

Bisphenol A（BPA） plays an important role in metabolic disorders. As a major alternative to BPA, it is unclear whether the exposure of bisphenol S（BPS） may result in lipidome disturbance. Using a mouse model, we investigated the effects of BPS exposure on metabolism and spatial distribution of lipids by using lipidomics analysis and matrix-assisted laser desorption/ionization（MALDI）-mass spectrometry imaging（MSI） in mouse liver tissues. Lipid metabolites displayed significant up-regulation in phosphatidylethanolamines（PE）, lysophosphatidylcholines（LPC）, lysophosphatidylethanolamines（LPE） and lysophosphatidylserine（LPS） as well as remarkable down-regulation in phosphatidylcholine（PC） and phosphatidylserine（PS） in mouse liver after the exposure at 100 m g BPS/kg body weight/*** obtained results indicated that the lipidome of liver was perturbed significantly in glycerophospholipid（GP） fatty acid remodeling pathway upon the BPS exposure. We applied MSI and multivariate statistical analysis to evaluate the abundance variation of lipid markers in BPS-treated liver sections and to compare with the analytical results from olive oil-treated liver sections. Differential structural lipids with up-regulated PE（20：1/20：4）, LPC（20：4）, LPE（20：4）, LPS（33：4） and down-regulated PC（20：4/22：6）and PS（18：0/22：6）, which were related to GP fatty acid remodeling, changed and co-localized in the liver sections. To explore the cause of variation of lipid abundance, expression of enzymes that regulate biosynthesis and metabolism of fatty acid in liver tissues were analyzed. Consistent with the results of liver lipidome and spatial distribution, a decrease in hepatic expression of LPC acyltransferase 1（LPCAT1）,LPCAT2 and LPS acyltransferase and an increase expression of LPCAT3, LPCAT4, LPE acyltransferase 1（LPEAT1）, LPEAT2 and phospholipase A2 s were observed in GP fatty acid remodeling pathway. Our results demonstrated that exposure to BPS could induce the GP fatty acid remodeling, which m
