Azo dyes have been used in many industries (textile mill, printing and dyeing mill, paper and pulp mill) and have caused great environmental pollution due to complicated constitution and high chemical stability. The construction of azo dyes can be destroyed by ozonization, but not thoroughly when the ozone dosage is controlled to a certain extent and the operating cost is higher. Ozonization decomposed ability with ultrasonic enhancement on azo dyes has been demonstrated in the study. The conclusion derived from this investigation may be summarized as follows: (1) The decoloration rate of arsenazo I solutions during sono-zone treatment is more rapid than the rate obtained with ozone alone because the complicated constitution has been destroyed by the O free radical from ozone decomposition. (2) The destructing pathway of arsenazo I by ozone with ultrasound is identical with that of by ozone alone: the breakdown of-N=N-bonds, the conversion of benzene ring to car-boxylic acid, and-HSO3 bonds to H2SO4. So,

Preeclampsia(PE),a pregnancy-specific syndrome,is the leading cause of maternal and fetal morbidity and mortality and has been labeled the“great obstetrical syndrome”[1,2].Although the etiology and pathophysiology of PE are still not precisely understood,uncontrolled excessive inflammatory responses in the maternal decidua basalis and circulation have been identified as key contributors to PE development.

部分保险企业存在期限错配、流动性错配等投资扭曲问题,2018年实施的《关于规范金融机构资产管理业务的指导意见》(资管新规)可能会对这一问题产生影响。本文首先使用Hamilton方程对二者之间的关系进行理论分析,之后将资管新规实施作为准自然实验,以手工整理的2015-2021年保险企业投资数据为样本,分析这一政策对保险企业投资扭曲的影响效应及作用机理。研究表明:第一,政策显著缓解了高杠杆保险企业的投资扭曲程度;第二,政策对保险企业投资扭曲的缓解效应具有明显的异质性。规模较大以及未设有独立董事的保险企业受到的约束更强,投资扭曲缓解效果更好;经济发展水平高、民间金融活跃、保费密度较高的地区对政策的接受度和执行力更强,缓解效果也更显著;第三,在影响机制方面,政策主要通过降低保险企业资产负债的期限错配、流动性错配与信用错配程度来缓解企业投资扭曲水平;第四,高管的政策执行能力越强,资管新规缓解资金扭曲的效果越好。

A method for preparing a graphene oxide/polyaniline （GO/PANI） composite electrode was developed to investigate the effect of GO doped in PANI. PANI was first prepared by the polymerisation of aniline and then dedoped by NH4OH to form emeraldine base （EB）. The dedoped PANI and as-prepared GO were dissolved in N-methyl-2-pyrrolidone （NMP） to generate a homogeneous dispersion. The GO/PANI composites were redoped in HCI before use as electrode materials. These composites were characterised by Raman spectroscopy, X-ray diffraction, UV-vis adsorption spectroscopy, scanning electron microscopy, atomic force microscopy and electrochemical measurements. The GO/PANI composite electrode （containing 2.5% GO） has an initial gravimetric capacitance of 896 F g-1 at a scan rate of 5 mV s-1 and a retention life of 51% after 500 cycles, which is an improvement over that of pure PANI （23%）. The results show that the synergy of GO and PANI attributes to the good electrochemical performance of the GO/PANI composite electrode.

In this paper, we use the variational method to study the efficiency loss of user equilibrium for the multi-class, multi-criterion traffic equilibrium with general tolls and a discrete set of value of. time. By introducing three important parameters k1, k2, k3, we derive several bounds of price of anarchy for this problem when tolls are considered and not considered as part of the system cost, with the cost-based criterion.
