World Journal of Pediatrics 2018年第4期14卷 383-391页

作者： Tiago Rodrigues de Lima Diego Augusto Santos Silva Physical Education department Federal University of Santa CatarinaProfessor Clementino de Britto Street362 ap 334 CapoeirasFlorianópolisSanta CatarinaBrazil

Background Good sleep quality is an essential component for growth, development, and physical and mental health of the individual, in addition to being a positive indicator of health and well-being. The objective of this study was to estimate the prevalence of poor sleep quality and to identify the association of poor sleep quality with sociodemographic factors, lifestyle, weight status, and associated aerobic fitness in adolescents. Methods This study included 1110 students aged 14–19 years from city of S?o José/SC, Brazil. Sleep quality of the subjects was assessed using a questionnaire and classified as adequate and low. Independent variables were gender, age, monthly household income, maternal education, school shift, global physical activity, proper diet, screen time, sleeping hours of full week, sleeping hours of weekdays, sleeping hours of weekends, weight status, and aerobic fitness. Binary logistic regression was used to estimate odds ratios and confidence intervals of 95%. Results Prevalence of poor sleep quality was 60.4%. More likely to have poor sleep quality were identified in female students (oR 1.68, 95% CI 1.11–2.55), whose mothers had higher levels of education (oR 1.44, 95% CI 1.20–1.73) and low aerobic fitness (oR 1.80, 95% CI 1.02–3.19). Conclusion Adolescents who were most likely to report poor sleep quality were female, those whose mothers had a higher educational level and had low aerobic fitness. Students with sedentary risk behavior were less likely of reporting poor sleep quality.

olfaction as a soldier——a review of the physiology and its present and future use in the military

引用

Military Medical Research 2017年第3期4卷 157-169页

作者： Palaniappan Ganesh Nagappan Somasundram Subramaniam de-Yun Wang School of Clinical Medicine University of Cambridge department of otolaryngology Ng Teng Fong General Hospital department of otolaryngology National University of Singapore National University Health System department of otolaryngology Yong Loo Lin School of Medicine National University of Singapore

olfaction is one of our 5 main qualitative sensory abilities. In this review, we have examined the physiology of olfaction from the olfactory receptor to the brain. Through analyzing the physiology of olfaction, we have found that the biochemistry of olfactory nerve stimulation is unique from that of other similar pathways. Upon receiving large amounts of input from the olfactory nerve, the olfactory bulb, followed by several layers of centrifugal and centripetal processing in the brain, has to sort the information from the input as well as integrate it with other inputs from the brain to develop a coherent understanding of the input. We then examined the implications of olfaction in the military, the practical applications of electronic noses and problems associated with injury to olfaction that could affect compensation and combat worthiness of a soldier following injury. In the military, olfaction can allow the army to perform at its best through 4 main methods, namely ensuring olfaction is consistent with other dimensions of perception(ensuring optimal olfaction ability in all soldiers in combat), understanding the impact of different common combat environments on the sense of smell, utilizing odor as a defense mechanism and using olfactory aids when necessary. Electronic noses are olfactory aids that have a large potential in the military ranging from saving lives through the detection of explosives to potential methods for improving combustion efficiency. There are several problems associated with injury to olfaction that should be considered when deciding on compensation and combat worthiness of the soldier following an injury.

肠道黏膜屏障阻碍病原物质入侵的第一道防线是由黏蛋白-2(MUC2)组成的肠道黏液层,覆盖于上皮细胞表面,由杯状细胞分泌而成。脂多糖(lipopolysaccharides, LPS)可通过损伤肠黏膜从而干扰屏障功能的正常发挥。论文对Caco-2/HT-29(3∶1)共培养模拟肠道上皮细胞,通过沉默黏蛋白-2(siMUC2)分析脂多糖对肠道黏液层屏障及其上皮紧密连接结构的影响。结果显示,与对照组相比,LPS组E-钙黏素(E-cadherin)、闭合蛋白mRNA表达量均明显降低。与LPS组相比,LPS+siMUC2组中连接蛋白(claudin)、连接附着分子(JAMA)、E-cadherin以及桥粒(desmosome) mRNA水平显著降低,细胞连接蛋白mRNA水平的下调可能影响细胞通透性进而导致屏障功能紊乱。说明黏蛋白-2作为黏液层骨架蛋白成分可以保护细胞紧密连接蛋白免受LPS的干扰。LPS可诱导Caco-2/HT-29细胞模型黏蛋白-2表达增多以及E-cadherin、闭合蛋白mRNA表达下调。当黏蛋白-2基因被沉默后,LPS可导致细胞紧密连接蛋白mRNA表达量的显著下降,提示肠道上皮细胞紧密连接的屏障功能可能被破坏。

Nuclear Science and Techniques 2005年第4期16卷 201-203页

作者： CAo Hong-Ping CHEN Huan-Guang LI de-Ming Shanghai Institute of Applied Physics the Chinese Academy of Sciences Shanghai 201800 Graduate School of the Chinese Academy of Sciences Beijing 100049

The picosecond accelerator (PA) is a low energy electron linear accelerator facility under commissioning, which is built for the experiment of ps level pulse radiolysis in Shanghai Institute of Applied Physics (SINAP). A practical distributed DA&C system for this facility has been developed. In view of the upgrading-ability and main-tainability of the control system and controlled devices, Advantech? distributed intelligent DA&C products are adopted into the control system. ADAM 5000/TCPs with the protocol of Modbus/TCP are employed to accomplish data acquisition and device control. The PC-compatible programmable logic controller, ADAM-5511, is also adopted to handle the interlocks and the emergency events. on the software side, the integrated software package King-view?V6.5, which friendly supports all Advantech products, has been used to develop the upper layer control logic and process the data. This paper describes the control system design and system architecture. The intelligent ADAM controllers and the software platform are also discussed in detail.

CAN-based Synchronized Motion Control for Induction Motors

引用

International Journal of Automation and computing 2009年第1期6卷 55-61页

作者： Jun Ren Chun-Wen Li de-Zong Zhao department of Automation Tsinghua University Beijing 100084 PRC

A control area network （CAN） based multi-motor synchronized motion control system with an advanced synchronized control strategy is proposed. The strategy is to incorporate the adjacent cross-coupling control strategy into the sliding mode control architecture. As illustrated by the four-induction-motor-based experimental results, the multi-motor synchronized motion control system, via the CAN bus, has been successfully implemented. With the employment of the advanced synchronized motion control strategy, the synchronization performance can be significantly improved.

Etching graphitic carbon nitride by acid for enhanced photocatalytic activity toward degradation of 4-nitrophenol

引用

Chinese Chemical Letters 2014年第9期25卷 1247-1251页

作者： Si-Zhan Wu Cai-Hong Chen Wei-de Zhang School of Chemistry and Chemical Engineering South China University of Technology

Graphitic carbon nitride （g-C3N4） with high photocatalytic activity toward degradation of 4-nitrophenol under visible light irradiation was prepared by HCI etching followed by ammonia neutralization. The structure, morphology, surface area, and photocatalytic properties of the prepared samples were studied. After treatment, the size of the g-C3N4 decreased from several micrometers to several hundred nanometers, and the specific area of the g-C3N4 increased from 11.5 m2/g to 115 m2/g. Meanwhile, the photocatalytic activity of g-C3N4 was significantly improved after treatment toward degradation of 4- nitrophenol under visible light irradiation. The degradation rate constant of the small particle g-C3N4 is 5.7 times of that of bulk g-C3N4, which makes it a promising visible light photocatalyst for future applications for water treatment and environmental remediation.
