BackgroundIn 2005, China established an internet-based Tuberculosis Information Management System (TBIMS) to monitor changes in tuberculosis (TB). Many scholars have conducted epidemiological research using TBIMS; however, few studies assessing control strategies have been performed based on this platform data. Henan province is a high TB incidence area in China where, in addition to following the nationwide TB strategies, a series of local intervention combinations have been implemented. ObjectiveOur study aims to evaluate the impact of nationwide TB intervention combinations on epidemiological changes and determine whether Henan province can achieve the World Health Organization’s (WHO) goal of reducing TB incidence by 50% and TB mortality by 75% by the year 2025. MethodsWe used descriptive statistical methods to show the spatial and temporal distribution of pulmonary tuberculosis (PTB) reported to the TBIMS database from 2005 to 2018, and logistic regression analysis was performed to identify the risk factors of bacteriological-positive TB. The dynamic compartmental model and Bayesian melding approach was adopted to estimate the burden of TB under the impact of different TB control policies. ResultsIn total, 976,526 PTB cases were notified to the TBIMS in Henan in a period of 14 years. Although the overall incidence of PTB declined from 91.4/105 to 58.5/105, and the overall incidence of bacteriological-positive PTB declined from 44.5/105 to 14.7/105, the WHO’s 2025 goal could not be met. The distribution of high incidence and poverty-stricken counties were basically overlapped. Men, farmers and herdsmen (in rural areas), and subjects aged ≥60 years were more likely to develop bacteriological-positive PTB. The increasing treatment success for drug-susceptible tuberculosis and multidrug-resistant tuberculosis has not provided the desired reduction in incidence and mortality. ConclusionsTo achieve the targeted goal, while improving the cure rate of TB, new active (rather than passive) detection and intervention strategies should be formulated based on epidemiological characteristics in Henan province.

As one of the most advanced film forming technologies, the surface-initiated controlled/living radical polymerization provides an effective method for in-situ fabricating functional films on material surface. In this paper, the triazole film of polymerized (1-tosyl-1H-1,2,3-triazol-4-yl) methyl acrylate (P-TTMA) is in-situ prepared on copper surface via Cu catalyzed surface-initiated atom transfer radical polymerization (SI-ATRP) method. The P-TTMA film with different degree of polymerization (DP) is obtained by varying its molecular weight, which is achieved via regulating the polymerization time of SI-ATRP reaction. When the polymerization time is within 48 h, the SI-ATRP system can achieve a regular chain growth of P-TTMA film, the DP value of P-TTMA film shows an S-shaped variation as the polymerization time increasing. The electrochemical test is performed to evaluate the anticorrosion performance of different P-TTMA films for copper. The result demonstrates that the P-TTMA films exhibit good anticorrosion performance for Cu in 3.5 wt% NaCl solution. The P-TTMA obtained by 48 h polymerization time, with the DP value of 105, exhibits the stable and good protection performance. The anticorrosion performance of P-TTMA film can be optimized via regulating the SI-ATRP reaction. This paper provides a new idea for preparing inhibition film with a certain degree of polymerization and protection performance on metal surface. It is expected to be a theoretical guidance for fabricating triazole polymer film using ATRP with lower catalyst loading or metal-free ATRP in the coming future.

Academic libraries have long recognised the benefits of integrating information literacy into disciplinary curricula. One model that addresses the common problems of sustainability and scalability of such efforts is the train the trainer model, where academic librarians serve as faculty developers. Improving faculty development efforts requires understanding the methods and strategies of librarians engaged in this work. Using an action research methodology, this paper investigated the experiences of librarians and disciplinary instructors participating in a course redesign program at a large, public university in the midwestern United States, in order to identify effective strategies for engaging with disciplinary instructors about information literacy. Findings include focusing on pragmatic, contextual ways in which students will need to use information in the future, providing professional development opportunities for librarians to further develop faculty development skills, and prioritising strong collaborations between librarians and other academic units.

In order to investigate the effect of different copper surface state on the protection performance of triazole click-assembly film on Cu in circulating cooling water of power plants，the triazole inhibition films (CuMA-PR，Cu2OMA-PR，CuOMA-PR) were prepared via an in-situ click assembling reaction using p-toluenesulfonyl azide (MA) and propionic acid (PR) as assembly units on different copper surface state.Corrosion inhibition performance of the triazole inhibition films on copper substrate was evaluated by electrochemical method，corrosion coupon testing，SEM characterization and antibacterial property analysis.At the same time，the protective effect of Cu2OMA-PR on copper substrate in the circulating cooling water system of power plant was investigated.Results showed that Cu2O surface state was the best for the formation of triazole inhibition film(Cu2OMA-PR).The Cu2OMA-PR exhibited an excellent corrosion inhibition and antibacterial property on copper substrate within 21 d.The average inhibition efficiency of Cu2OMA-PR for copper in 3 weeks was 85.4%.Besides，Cu2OMA-PR could also effectively inhibit the proliferation of various microbial communities.

Ionic thermoelectric (i-TE) technologies can power Internet of Things (IoT) sensors by harvesting thermal energy from the environment because of their large thermopowers. Present research focuses mostly on using the interactions between ions and matrices to enhance i-TE performance, but i-TE materials can benefit from utilizing different methods to control ion transport. Here, we introduced a new strategy that employs an ion entanglement effect. A giant thermopower of 28 ​mV ​K−1 was obtained in a quasi-solid-state i-TE Gelatin-CF3SO3K–CH3SO3K gel via entanglement between CF3SO3− and CH3SO3− anions. The anionic entanglement effect involves complex interactions between these two anions, slowing anionic thermodiffusion and thus suppressing bipolar effects and boosting p-type thermopower. A Au@Cu | Gelatin-CF3SO3K–CH3SO3K | Au@Cu i-TE device with a generator mode delivers a specific output energy density of 67.2 ​mJ ​m−2 K−2 during 2 ​h of discharging. Long-term operation of the i-TE generator for 10 days shows that the harvested energy density offers an average of 2 ​J ​m−2 per day in a cyclic working-reactivation model at a temperature difference of 6 ​K. The results demonstrate that anionic entanglement is an effective strategy for achieving giant thermopower with i-TE gels, so they have excellent potential for powering IoT sensors.
