卫生陶瓷生产的新思路

1.背景改革开放以来,我国的建筑卫生陶瓷工业得到了长足的发展。而引进对提高我国建筑卫生陶瓷生产的技术装备,开阔工艺路线和经营规模的思路,都起到了十分有益的推进作用。引进设备的产量估计约占全国总产量的一半,但我国建筑卫生陶瓷的产品,在国际市场上所占份额尚不够大,而国内高级宾馆及大型民用建筑的卫生洁具,进口产品仍占主导地位,这种现象颇值得深思,表明我国建筑卫生陶瓷工业发展的不平衡,尚未形成完整的、具有中国特色的生产体系。     

我国建筑卫生陶瓷的现状及发展

加入WTO对我国建筑卫生陶瓷行业的影响及对策

目前，我国建筑卫生陶瓷生产有两大特点：一是建筑卫生陶瓷生产企业过多，其数量堪称世界第一。然而，中小型建筑卫生陶瓷企业占总数的90％左右，其中设备陈旧，技术落后和陷于亏损的企业占有相当大的比例，二是产品严重过剩。在出口无大幅增长，国内消费依然低迷的情况下，又会过剩相当多的建筑卫生陶瓷产品。

Reactions in Stabilizer and Between Stabilizer and Nitrocellulose in Propellants

HPLC analysis of the stabilizer is one of the major methods in use for surveillance testing of diphenylamine (DPA) stabilized propellants. Often 0.2% DPA is used as a minimum content for safe propellants. In most cases the propellant can be stored much longer after this limit has been reached without any risk for self‐ignition. We report here about a reaction where DPA bonds to nitrocellulose, leaving a non extractable aromatic stabilizing compound left in the propellant, resulting in a longer time to autocatalysis than predicted. Diphenylnitramine is discussed as a possible intermediary compound occurring from the reaction between DPA and nitrocellulose. This should add to a better understanding of the degradation processes in propellants.     

Differences in color naming and color salience in Vietnamese and English

The accepted model of color naming postulates that 11 “basic” color terms representing 11 common perceptual experiences show increased processing salience due to a theorized linkage between perception, visual neurophysiology, and cognition. We tested this theory, originally proposed by Berlin and Kay in 1969. Experiment 1 tested salience by comparing unconstrained color naming across two languages, English and Vietnamese. Results were compared with previous research by Berlin and Kay, Boynton and Olson, and colleagues. Experiment 2 validated our stimuli by comparing OSA, Munsell, and newly rendered “basic” exemplars using colorimetry and behavioral measures. Our results show that the relationship between the visual and verbal domains is more complex than current theory acknowledges. An interpoint distance model of color‐naming behavior is proposed as an alternative perspective on color‐naming universality and color‐category structure. © 2003 Wiley Periodicals, Inc.

Designer enzyme and cell applications in industry and in environmental monitoring

Renewed world interest in enzyme biotechnological industries now derives from the expectation that many new biocatalysts will be created by genetic engineering associated with protein engineering designer techniques, or by chemical modification of existing enzymes by use of protein tailoring methods. The biocatalysts produced are mainly enzymes, abzymes (catalytic antibodies) and synthesis (synthetic analogues or mimics), and these will be used in industry, synthesis, therapy: and in bioanalysis of components of foodstuffs, and the environment including water, air and soil. The biocatalysts, including whole cells, are firstly incorporated into a particular bioreactor form by use of enzyme engineering techniques such as immobilization, and are then used, as appropriate, to modify their substrates. Improved processing or enhanced products are thereby achieved in the case of manufacturing industry: or monitoring signals are generated, often in the form of a measurable change in current flow, in the case of environmental biosensors. Designer enzymes and cells can be made now for identified applications where the presently available biocatalysts are inadequate, incompatible or uncompetitive.     

EZH2 Down-Regulation Exacerbates Lipid Accumulation and Inflammation in in Vitro and in Vivo NAFLD

Non-alcoholic fatty liver disease (NAFLD) is one of the most prevalent, chronic liver diseases, worldwide. It is a multifactorial disease caused by complex interactions between genetic, epigenetic and environmental factors. Recently, several microRNAs, some of which epigenetically regulated, have been found to be up- and/or down-regulated during NAFLD development. However, in NAFLD, the essential role of the Polycomb Group protein Enhancer of Zeste Homolog 2 (EZH2), which controls the epigenetic silencing of specific genes and/or microRNAs by trimethylating Lys27 on histone H3, still remains unknown. In this study, we demonstrate that the nuclear expression/activity of the EZH2 protein is down-regulated both in livers from NAFLD rats and in the free fatty acid-treated HepG2. The drop in EZH2 is inversely correlated with: (i) lipid accumulation; (ii) the expression of pro-inflammatory markers including TNF-α and TGF-β; and (iii) the expression of miR-200b and miR-155. Consistently, the pharmacological inhibition of EZH2 by 3-Deazaneplanocin A (DZNep) significantly reduces EZH2 expression/activity, while it increases lipid accumulation, inflammatory molecules and microRNAs. In conclusion, the results of this study suggest that the defective activity of EZH2 can enhance the NAFLD development by favouring steatosis and the de-repression of the inflammatory genes and that of specific microRNAs.
