Sustainability analysis of reused industrial buildings in China: an assessment method

The sustainable development of old industrial buildings is in line with the national construction strategy and has an important impact on current urban renewal. Only by achieving a unified balance among economic, social, and environmental factors can reused industrial buildings be considered sustainable. However, there are no relevant sustainability assessment indicators and methods for reused industrial buildings in China. The purpose of this study was to provide a reasonable and effective method for assessing the sustainability of reused industrial buildings. First, this study analysed the factors influencing reused industrial building sustainability through a project investigation. Second, based on the assessment indicator setting procedure, the sustainability assessment indicator system for reused industrial buildings was optimised. Moreover, a multi-level sustainability assessment model based on extenics was established to identify the correlation functions of indicators with different attributes. Finally, a case was considered to verify this assessment method. The results showed that this assessment method in good agreement with the actual state of the case was validated to be more effective and practical. The assessment method could provide a basis for decision-making to improve sustainability and could be adopted by relevant rating agencies to determine the sustainability level of reused industrial buildings

Secondhand smoke exposure assessment and counseling in the Chinese pediatric setting: a qualitative study

Background: Assisting smoking parents to quit smoking and eliminating the secondhand smoke (SHS) exposure of their children is a global health priority. Engaging healthcare workers in developing countries to address this priority has been a challenge. This study intends to explore issues around current practice related to SHS exposure assessment and counseling and identify barriers to SHS exposure reduction counseling in the Chinese pediatric setting. Methods: We conducted qualitative interviews (11 focus groups discussions (FGDs) with pediatricians, 6 FGDs with pediatric nurses and 11 in-depth interviews (IDIs) with hospital administrators) among 101 health-care professionals (HCP) from 5 hospitals in four major cities of Guangxi Province, China. All FGDs/ IDIs were audio recorded and analysed thematically. Results: The findings suggest that few Chinese pediatricians routinely address the SHS exposure of children in their usual practice. All HCPs felt the need for clinical interventions to promote SHS exposure reduction for children. Primary barriers to SHS exposure reduction counseling in the Chinese pediatric setting included: lack of skills and training in tobacco use reduction and cessation counseling; time constraints and heavy workloads, uncertainty about the usefulness of smoking cessation interventions and lack of hospital-wide systems requiring pediatricians to record tobacco use or SHS exposure information. Ideas for overcoming these barriers were building capacity of pediatricians, collaboration with international organization to initiate training, engaging top level leaders in the effort and ensuring financial resources to support the program. Conclusions: This study among hospital administrators and service providers in China demonstrated a high level of interest in delivering SHS exposure reduction interventions in the pediatric setting. The findings can inform the creation and delivery of clinical interventions in China to promote SHS exposure reduction to children in the pediatric setting.

Ammonium fluoride additive-modified interphase chemistry stabilizes zinc anodes in aqueous electrolytes

Herein, ammonium fluoride is reported as an additive within 1 M ZnSO4 aqueous electrolyte to improve zinc anodes. The as-formed electrostatic shielding layer and ZnF2-rich solid-state interphase layer can jointly inhibit side reactions and dendrite growth. Consequently, symmetric Zn‖Zn cells, asymmetric Zn‖Cu cells and Zn‖MnO2 cells with the additives present dramatically enhanced performance in comparison to the ones with pure ZnSO4 electrolyte counterparts. This work proposes a facile but effective method to achieve highly reversible zinc anodes

Electrotunable liquid sulfur microdroplets.

Manipulating liquids with tunable shape and optical functionalities in real time is important for electroactive flow devices and optoelectronic devices, but remains a great challenge. Here, we demonstrate electrotunable liquid sulfur microdroplets in an electrochemical cell. We observe electrowetting and merging of sulfur droplets under different potentiostatic conditions, and successfully control these processes via selective design of sulfiphilic/sulfiphobic substrates. Moreover, we employ the electrowetting phenomena to create a microlens based on the liquid sulfur microdroplets and tune its characteristics in real time through changing the shape of the liquid microdroplets in a fast, repeatable, and controlled manner. These studies demonstrate a powerful in situ optical battery platform for unraveling the complex reaction mechanism of sulfur chemistries and for exploring the rich material properties of the liquid sulfur, which shed light on the applications of liquid sulfur droplets in devices such as microlenses, and potentially other electrotunable and optoelectronic devices

CENet: A Cabinet Environmental Sensing Network

For data center cooling and intelligent substation systems, real time cabinet environmental monitoring is a strong requirement. Monitoring data, such as temperature, humidity, and noise, is important for operators to manage the facilities in cabinets. We here propose a sensing network, called CENet, which is energy efficient and reliable for cabinet environmental monitoring. CENet achieves above 93% reliable data yield and sends fewer beacons compared to periodic beaconing. It does so through a data-aided routing protocol. In addition, based on B-MAC, we propose a scheduling scheme to increase the lifetime of the network by reducing unnecessary message snooping and channel listening, thus it is more energy efficient than B-MAC. The performance of CENet is evaluated by simulations and experiments

Are Chinese pediatricians missing the opportunity to help parents quit smoking?

Background: Secondhand smoke (SHS) exposure of children due to parental tobacco use is a particularly prevalent health issue and is associated with adverse health outcomes. Following the US Clinical Practice guidelines, pediatricians in the United States deliver 5A’s (ask, advise, assess, assist, and arrange) counseling to smoking parents which has proven to be effective. We examined Chinese pediatricians’ adherence to the clinical practice guidelines for smoking cessation (i.e. 5A’s counseling practices) with smoking parents, and identified factors associated with these practices. Methods: A cross-sectional paper-and-pencil survey of pediatricians was conducted in twelve conveniently selected southern Chinese hospitals. Factors associated with any of the 5A’s smoking cessation counseling practices were identified by logistic regression. Results: Of respondents (504/550), only 26 % routinely provided 5A’s smoking cessation counseling to smoking parents. More than 80 % of pediatricians didn’t receive formal training in smoking cessation and had not read China smoking cessation guidelines; 24 % reported being “very confident” in discussing smoking or SHS reduction with parents. Pediatricians who had never smoked (OR: 2.29, CI:1.02-5.12), received training in smoking cessation (OR: 2.50, CI:1.40-4.48), had read China smoking cessation guidelines (OR: 2.17, CI:1.10-4.26), and felt very (OR: 7.12, CI:2.45-20.70) or somewhat (OR: 3.05, CI:1.11-8.37) confident in delivering cessation counseling were more likely to practice 5A’s. Pediatricians who reported “it is hard to find a time to talk with parents” (OR: 0.32, CI: 0.11-0.92) or “lack of a standard of care requiring pediatricians to provide smoking cessation or SHS exposure reduction intervention” (OR: 0.45, CI: 0.21-0.98) as a barrier were less likely to follow the 5A’s guidelines. Conclusions: Smoking cessation counseling to address parental smoking is infrequent among Chinese pediatricians. There is a need to develop and test intervention strategies to improve the delivery of 5A’s smoking cessation counseling to parental smokers

Genome‑wide association analyses of leaf rust resistance in cultivated emmer wheat

Leaf rust, caused by Puccinia triticina (Pt), constantly threatens durum (Triticum turgidum ssp. durum) and bread wheat (Triticum aestivum) production worldwide. A Pt race BBBQD detected in California in 2009 poses a potential threat to durum production in North America because resistance source to this race is rare in durum germplasm. To find new resistance sources, we assessed a panel of 180 cultivated emmer wheat (Triticum turgidum ssp. dicoccum) accessions for seedling resistance to BBBQD and for adult resistance to a mixture of durum-specific races BBBQJ, CCMSS, and MCDSS in the field, and genotyped the panel using genotype-by-sequencing (GBS) and the 9 K SNP (Single Nucleotide Polymorphism) Infinium array. The results showed 24 and nine accessions consistently exhibited seedling and adult resistance, respectively, with two accessions providing resistance at both stages. We performed genome-wide association studies using 46,383 GBS and 4,331 9 K SNP markers and identified 15 quantitative trait loci (QTL) for seedling resistance located mostly on chromosomes 2B and 6B, and 11 QTL for adult resistance on 2B, 3B and 6A. Of these QTL, one might be associated with leaf rust resistance (Lr) gene Lr53, and two with the QTL previously reported in durum or hexaploid wheat. The remaining QTL are potentially associated with new Lr genes. Further linkage analysis and gene cloning are necessary to identify the causal genes underlying these QTL. The emmer accessions with high levels of resistance will be useful for developing mapping populations and adapted durum germplasm and varieties with resistance to the durum-specific races

Chinese pediatrician beliefs about counseling and medications for parents who smoke: a survey in southern China

Background: Pediatricians play an important role in promoting smoking cessation among the parents of young children as more behavioral counseling and cessation treatment are made available in the Chinese healthcare system. However, beliefs about the effectiveness of these interventions can influence pediatricians’ recommendations to their patients. This study examined pediatricians’ beliefs regarding effectiveness of counseling and medications for smoking cessation. Methods: A cross-sectional survey of pediatricians was conducted in thirteen conveniently selected southern Chinese hospitals, during September to December 2013. A self-administered questionnaire was used for data collection. We used chi square tests and multinomial logistic regression analysis to identify factors associated with beliefs regarding effectiveness of counseling and medications for smoking cessation. Results: Beliefs of the respondents (504/550; 92% response rate) were divided regarding the effectiveness of counseling and medications for smoking cessation. Sixty percent believed that physician counseling is effective for smoking cessation; 53% believed pharmacological products (or medications) are effective. Factors that were associated with positive beliefs towards the effectiveness of counseling included: believing about the professional responsibility to discuss smoking cessation, being confident in discussing smoking cessation or SHS exposure reduction with patients’ parents, believing that health professionals should routinely ask about their patients smoking habits, believing that health professionals should routinely advise their smoking patients to quit smoking, possessing adequate knowledge in quitting smoking, and being able to assess smokers different stages of readiness to quit. Most of the above factors were also associated with the belief that medication is effective for smoking cessation. Conclusions: A substantial proportion of Chinese pediatricians believed that cessation counseling and medications are not effective, which is not supported by current evidence in the field. Several factors including individual, practice level and health system level characteristics were associated with their belief. Training efforts are needed to influence pediatricians’ beliefs regarding the effectiveness of cessation counseling and medications
