作者： Chen Shi Xia Jintao Hola Kora China

Through the deep data analysis of the cosmetics industry, it can be found that the changes in population structure, differences of consumption habits, and income factors which have led to the intergenerational replacement of Chinese consumers. Middle-aged crowd in China, their consumption concept tend to be relatively conservative, while for young generations, their income level is becoming higher. The purchasing power and consumption tendency of such young consumer groups are significantly higher than that of middle-aged and elderly people. Relevant data show that the consumption intention and consumer confidence index of the new generation (born in 1995 and beyond) are significantly higher than the overall level of ditferent age groups, and the growth rate are accelerating. In the urban residents’ consumption in 2012, the contribution of the new generation is 15%, and it is expected to reach 35% by 2020, which fully shows that the new generation of consumers has begun to become the mainstream of new generation consumption.

With development of foreign language education in China, more and more people pay attention to the research of the mainstream EFL teaching styles, which combines the seemingly contradictory points of both traditional and current linguistic theories and use them well in foreign language teaching. With special features, the mainstream EFL teaching style has its advantage and weakness and it needs much improvement in teaching process.

Retention mechanism of phenol in mainstream cigarette smoke by cellulose acetate filters

中国烟草学会2017年学术年会

作者：陈敏 Leijun Wang Huizhong Dong Xi Shao Da Wu Baizhan Liu Xiangmin Zhang Chaoying Chen Department of Chemistry Fudan University Technology Center Shanghai Tobacco Group Co. Ltd.

A heart-cutting two dimensional liquid chromatography coupled with tandem mass spectrometry method was developed for the analysis of tobacco-specific nitrosamines at low concentration level in Virginia type cigarette smoke. A strong cation exchange column was utilized for the first dimensional separation, which effectively removed acidic and neutral components in the smoke, followed by a reversed phase liquid chromatography coupled with tandem mass spectrometric analysis. To capture components of the tobacco-specific nitrosamines in the effluent on the trapping column, a compensating pump was applied for on-line dilution and p H adjustment during the period of the tobacco-specific nitrosamines fraction transferring and enrichment. High sensitive determination of the tobacco-specific nitrosamines in mainstream cigarette smoke was achieved by isotope deuterated internal standards under the multiple reaction monitoring mode. Compared with traditional methodologies, the method was almost no matrix interference. Limits of quantity for the tobacco-specific nitrosamines were within 0.027 - 0.094 ng/mL. And the results showed good reproducibility and accuracy. Finally, the new method was applied to analysis of the Kentucky reference cigarettes and the results agreed well with joint experiments of Cooperation Centre for Scientific Research Relative to Tobacco.

To understand the retention mechanism of phenol in mainstream cigarette smoke by cellulose acetate(CA)filters,the phenol filtration efficiency,the phenol distribution in the gas phase and particulate phase during filtration and the retention characteristics of the filter for both the gas phase and particulate phenol species were *** distribution of particulate bound phenol as a function of the particle size was *** ratio of phenol transferring from the particulate phase to the gas phase during smoke flowing through the CA filter were *** mechanisms for phenol in the gas phase as well as particulate phase phenol in the filter and the phase transition of phenol were *** filtration efficiency of the cigarette filter was calculated based on the proposed retention mechanisms and compared with available experimental *** results showed that:1)Comparing with nicotine and the other particulate bound smoke constituents,CA filter exhibited a certain retention selectivity for phenol.2)Although phenol was mainly bound to the particulate phase of the cigarette mainstream smoke,about 35% of gas phase phenol was found at the tobacco end of the filter,whilst this dropped to approximately 0 at the mouth end of the filter,mostly by selective chemical adsorption.3)The weighted average smoke particle size and particulate phenol was 0.44 and 0.38 pm,*** filtration efficiency of the filter to particulate phenol was near 40%.4)About 19% of particulate bound phenol transferred to gas phase when smoke passing the filter,and was selectively adsorbed.5)The overall filtration efficiency of the CA filter for phenol in mainstream cigarette smoke was 68.7%,with-7.7% variation compared with experimental *** results demonstrated the phase transition of phenol during the filtration process and the selective retention with varying particle *** results showed that the application of CA filter in product designs reduces harmful

The adoption and use of social media has played a major role in the changes in journalists’ work. The use of these new means has become indispensable to the daily tasks and work of journalists in most news organizations. It is no longer possible to bypass these means when it comes to searching for information and news, or in production, publishing, distribution and marketing, or even in interaction with the public. The characteristics of ease, speed, immediacy, interactivity, and being free of charge that characterize them, have made them a useful technological tool, which is influential and necessary not only for the future of the journalist’s career but also for the future of the news organization itself. With the growing number of users of social media around the world, journalists and news organizations have found additional access, more important than previous channels, to access additional sources that help them market and interact with their work in a new dynamic environment completely different from previous communication models, and put audience activity at the forefront. In this study, which is part of the Technology Acceptance Model (TAM), the author tries to understand and analyze the factors of adoption and use of social media as a new technological tool by Bahraini journalists and to identify their new role in the changes in journalism. In addition, the study attempts to examine the implications in relation to the future of the press profession and the economic model of the news organization. The results showed a clear adoption and an increased use of social media by journalists, who consider it a key element in the development of journalism, and an inevitable strategic choice for the future of the news organization. They also expressed their full awareness of the problems surrounding the issue of precision and credibility of news accessed through social media.
