Wet air oxidation is an effective method to deal with highly concentrated nondegradable emulsification wastewater which contains non-ionic surfactants. This article illustrates our investigation on dynamic characteristics of wet air oxidation of typical non-ionic surfactants like polyether, phenol ether and widely used alcohol ether. The experimental results indicated that the oxidation rate of polyether, phenol ether and alcohol ether obviously ascended as the temperature rose. A good oxidation effect was available at 240°C. The TOC removal rate could reach 88.0%, 94% and 91.5%, after 125 min reaction. Alcohol ether was prone to an easier oxidation compared with polyether and phenol ether when the temperature was 220°C or below. The oxidation rate of alcohol ether was higher than that of polyether at 160°C, while the oxidation rate of polyether was higher than that of phenol ether between 180°C and 220°C. During the later period of the reaction at 240°C, the rate of phenol ether was higher than that of alcohol ether, which was still higher than that of polyether. Partitioned first order kinetics model analysis showed that the apparent activation energy of alcohol ether was lower than that of both polyether and phenol ether in the leading stage and lagging stage, and it was easy to acquire a higher oxidation rate for alcohol ether at low temperature. Three parameter general dynamics model analyses showed that the reason why the oxidation rate of polyether was lower than that of alcohol ether was that the oxidation of polyether was more apt to be converted to intermediate production than that of alcohol ether, whereas between 200°C and 220°C, the direct oxidation rate of polyether and the oxidation rate of intermediate product were obviously lower than that of alcohol ether. The apparent activation energy of direct and indirect oxidation of polyether was 43.37 and 60.45 kJ·mol?1, respectively, while the corresponding apparent activation energy of alcohol was 38.74 an

在当今社会,网络空间已日益成为人们彼此之间分享信息、交换意见,以及进行情感交流的重要场域。由于网络空间具有虚拟性、自主性、开放性、包容性的特点,以及各种新媒体技术具有极高的表现力,人们的语言创造力得到了极大的激发,网络语言随之也蓬勃发展起来。于根元(2001)指出,网络语言是一种网络空间常用的“独特的自然语言”。[1]一般认为,虚拟空间所使用的语言具有临时、短暂性的特点,使得人们可以在短时间内观察到某些词语出现、消亡的整个过程。

以福建省漳州尾巨桉(Eucalyptus urophylla×***)人工林为研究对象,研究物理去除灌草和施用除草剂2种灌草管理方式对尾巨桉人工林土壤CO2排放和凋落物分解的影响。实验时间为2012年12月至2014年11月,采用LI-COR 8100系统测定土壤呼吸,用分解袋法开展分解实验。结果表明,物理去除灌草方式下土壤温度显著升高,但土壤CO2排放降低;施用除草剂对土壤温度和土壤CO2排放无明显影响。土壤呼吸有明显的季节变化,在雨季较高,在旱季则明显降低。土壤呼吸的温度敏感系数Q10表现为去除灌草(2.49)>对照(2.38)>施用除草剂(2.15)。研究表明不同的灌草管理方式对人工林土壤碳循环影响有差异,物理去除对土壤碳排放和物质循环的效应大于施用除草剂。

Long-term artificial sweetener intake is linked to increased risk of obesity. In the present study, supplement of natural sweetener from Siraitia grosvenorii(SG)(or Momordica grosvenorii) fruit, compared with the artificial sweetener aspartame(ASM), was evaluated for anti-obesity effects on mice fed with high fat diet(HFD). We found that, in contrary to ASM, SG extracts prevented body weight gain, the insulin resistance and fat mass accumulation in HFD mice. SG extracts treatment inhibited the infiltration of inflammatory macrophages and lowered the levels of the fat inflammatory cytokines(leptin, macrophage chemoattractant protein 1(MCP-1) and tumor necrosis factor-α(TNF-α)) in adipose tissues. In addition, SG extracts supplement counteracted the remodeling of gut microbiota resulted from HFD. However, ASM supplement aggravated the HFD-induced obese performances, fat inflammation and dysregulation of gut microbiota. Taken together, our results indicate that supplement of SG extracts may represent a promising alternation of artificial sweeteners in preventing metabolic diseases.

The fundamental importance of sex lies in the need for reproduction and species continuity. For humans, sexual expression is an important source of physical pleasure and emotional intimacy. Healthy sexual expression is closely related to well-being, health and overall quality of life in both men and women. Sexual activity is also considered an important determinant of quality of life. At present, questions about sex are still largely ignored in routine consultations in almost all medical specialties. The factors affecting sexual activity are complex and can be divided into the influence of bio-psycho-sociological factors. Biological influences include anthropometric parameters, sexual function, lifestyle, neuroendocrine system, and diseases;psychological influences include psychological status, mental illness, and sexual attitudes;sociological influences include factors such as marriage, occupation, and economic status. With the epidemic and outbreak of Coronavirus disease 2019 (COVID-19), people’s way of life and work has changed, which also has a great impact on sexual activities. This article will provide a systematic review of factors related to male sexual activity.
