Core–shell ZIFs wrapped CuO hybrid materials (CuO@ZIF-67(Co)) were designed, synthesized, characterized, and employed as peroxymonosulfate (PMS) activators to degrade methylene blue (MB). It demonstrated outstanding catalytic activity on account of the unique structure and the synergistic effect between CuO cores and ZIF-67(Co) shells, resulting in complete degradation of MB (10 mg/L) in 1 min. Reactive oxygen species (ROSs) research showed that both SO4 − and OH were responsible for the removal of MB. The synergistic activation mechanisms in the CuO@ZIF-67(Co)/PMS system were investigated, which mainly involved the effective electron transfer of CuO and ZIF-67(Co) for accelerating the cycle of CuII/ CuI and CoIII/ CoII. This study broadens the application of MOF-derived materials for wastewater treatment.

Counterfeit luxury is big business in China (Chen et al. 2018). The U.S. Chamber of Commerce estimates China to be the source of 86% of the world’s counterfeit luxury goods worth about $397bn (USCC 2016). Counterfeit luxury encompasses not only low quality replicas (Lai and Zaichkowsky 1999), but also high quality products that are appear almost identical to original brands. However, the price of high quality counterfeits amounts in many cases to only 10% of that of the originals (Geiger-Oneto et al. 2013). This makes high quality counterfeit luxury brands a major threat to established luxury brands. Luxury brand marketers, therefore, require a better understanding of what motivates target consumers to purchase either original or counterfeit luxury brands.

The purpose of this study was to measure the mean peak mobilization forces to the lumbar spine 1-3 with grade III and grade IV of posteroanterior (PA) mobilization. Twenty subjects with no history of Lumbar back pain (LBP) (10 female, 10 male) with a mean age of 24.1 years (SD = 6.0) were recruited for the study and PA mobilization were performed in each spine and the therapist took approximately 2.5s to complete mobilization. In the results, applied grade IV force showed no different according to each segment in LS1, LS2, LS3, however, there are distinct differences between LS1 and LS2, LS1 and LS3 during mobilization with grade III force. This study suggested that the mean peak force of the grade III and grade IV mobilization in the L1-L3 was almost similar each other.

The global economic and financial conditions in 2010 and 2011 were positive and the business trade grew at about twice of the rate of that in 2009. The container shipping players started to enjoy a new chapter of international business trade having struggled to operate their vessels since 2008. So we now have to consider if the shipping business will return to its old strategy? What will happen to the container shipping sector in 10 years from now still remains uncertain. Recently, the uncertain situation globally has been giving shipping companies in difficulty the opportunity to make decision as to whether it is necessary to use super slow steaming for containerships. Therefore, the aim of this study is to analyse the necessity of super slow steaming on containerships despite such uncertainty. A Fuzzy Rule-based Bayesian Reasoning method has been used which incorporates the membership function and 14 selected nodes. Finally, the outcome of this study is 48 rules which have been proposed to assist shipping companies in their decision making processes when dealing with the dynamic business environment. Each rule gives a clear-cut understanding of the result which is able to be applied to real situations the containership industry faces.

In the design of urban rail traffic entrances and ventilation pavilion in the city of Zhengzhou, Henan province, this study tries to explore a kind of regional appearance about the subway entrances and ventilation pavilion design in the new period through the combination of sustainable building ideology [ 1] and local culture. The creation inspiration of the design is from the aspects of humanism, and the design tries to make the building have distinct regional characteristic in the premise of the contemporary feeling with the rational method. The building is located in the central plains , where the cultural resources are very rich. The design tries to choose clements that are from the famous cultural heritage and appeared appropriately in the plan, which to read and promote culture with the perspective of modem style architecture, and also make the subway entrance building have local differences and the identify ability. In the deepening of the design, the green and sustainable thought is the main exploration direction. The design tries to use High-tech building materials, and shows the building texture with the Combination of ETFE (ethylene-tetra-fluoric-ethylene) and steel skeleton, which appear the structure and the form of the building in the new period with the eco-friendly style. At the same time, the design discusses the way of Subway Entrances and the ventilation pavilion in central plains under the constraints of geography, climate and function.

The authors calculate the long-term predictability of GDP, domestic demand, investment, and net exports for Guangdong province, P.R. China from 2000 to 2013. A vector autoregressive (VAR) model with quarterly data for this period is first co-integrated then the Granger causality test is applied to empirically assess the relationships among gross domestic product (GDP), consumption, investment, and net exports. There is a strong causality effect between investment and net exports in Guangdong province. However, the variance decomposition results indicate that exports respond to foreign shocks rather than domestic ones, making their impact on the Guangdong economy to predict. Results show the stimulating effect of domestic demand on GDP is larger than the stimulating effect of net exports and much larger than even the stimulating effect of investment. The analysis suggests that there are dynamic influences with various levels of persistence between GDP, consumption, investment, and net exports. Macroeconomic policy adjustments are urgently required to expand domestic demand and thereby stimulate economic growth in Guangdong province.

Chromosome segment substitution lines (CSSLs), in which each line carries a single or a few defined chromosome segment of donor genome and has a pure genetic background from a recurrent genotype, is a fundamental approach to conduct the QTL mapping in order to improve the mapping precision. In the present study, variety ‘ZM36’ (Gossypium. hirsutum) and ‘Hai1’ (Gossypium. Barbadense) were used as recurrent and donor parent to produce a segment substitution lines populations, respectively. The results indicated that most of fiber quality traits, yield-related traits and verticillium wilt traits fit the normal distribution in the Kolmogorov-Smirnov test. In 133 lines of BC4S2:3 generation fiber length longer the recurrent parent has 37, micronaire lower than the recurrent parent has 58, Fiber strength over than the recurrent parent has 34. In 199 individuals of BC4S2:4 generation fiber length longer the recurrent parent has 37, micronaire lower than the recurrent parent has 36, Fiber strength over than the recurrent parent has 49. Fiber length had significantly positive correlation with fiber strength and negative correlation with micronaire, seed index had significantly positive correlation with boll weight and negative correlation with lint percentage, lint percentage had negative correlation with fiber length and strength.

Most traits of crop are quantitative, which are controlled by polygenes. Finely mapping ofquantitative trait loci (QTLs) is very important for cotton genetic improvement. Chromosome segment substitution lines (CSSLs) containing only one or a few segments of donor chromosome introgressed into a recipient genetic background can be used for QTL fine mapping and map-based cloning. In this study, the Gossypium. hirsutum variety ‘ZM36’ and Gossypium. barbadense ‘Hai1’ were respectively used as recurrent and donor parent to produce a segment substitution lines populations, including the BC4F2:3 and BC4S2:4 generations, by using microsatellite marker-assisted selection (MAS). We obtained 283 SSR marks by taking about the average 5 cM distance selection marks on this map, and these marks were carried to the molecular examination with to two populations. The results showedthat recurrent parent genetic background already to restore the very high degree through the high generation of backcross.
