To the Editor:During pregnancy,it is critical to obtain adequate micronutrients to ensure maternal and fetal health.Due to the rapidly increasing demand for micronutrients among pregnant women and that the demand is not being fulfilled by daily dietary intake,especially in resource-poor settings,micronutrient deficiency during pregnancy is very common worldwide and in China.[1]Previous studies in China reported that a high proportion of pregnant women had insufficient intakes of folate,vitamins,and calcium.[1]Of these insufficient intakes,calcium deficiency was the leading problem.[2]

The use of abundant elements in the earth as electrocatalytic hydrogen production catalysts is of great significance for hydrogen energy cycling.Herein,we report amorphous TiO_(2)-decorated CoP/NF(TiO_(2)–CoP/NF)as an excellent electrocatalyst for alkaline hydrogen evolution reaction(HER).The welldispersed amorphous TiO_(2)on nanoneedle-like CoP arrays preserves the crystal structure of CoP and changes its electronic structure by interfacial charge transfer.Compared to CoP/NF catalyst,the Ti O_(2)–CoP/NF composite catalyst exhibits high HER activity with an overpotential of 61 mV at 10 mA cm^(-2)and high stability.Importantly,it almost maintains the Volmer step as a rate-determining step(RDS)and the Tafel slope at a wide cathodic potential range showing the fast kinetics under large polarization regions.Theoretical simulations reveal that the combination of TiO_(2)and CoP selectively accelerates the hydrated K+diffusion,regulates the interfacial water orientation to adapt to the subsequent smooth water dissociation,and optimizes*H adsorption/H_(2)desorption.The strengthened coupling of HER multi-scale-processes on transition metal compound composites catalysts is the underlying mechanism for improving HER activity.

“毒品”范围的确定影响着毒品犯罪的定罪量刑。根据《刑法》第357条,我国毒品范围的确定采用的是“部分列举+抽象定义”模式。这种毒品范围确定模式在适用中容易产生两个方面问题:一是涉非列管物质犯罪认定问题;二是涉自用或医用型麻... 详细信息

“毒品”范围的确定影响着毒品犯罪的定罪量刑。根据《刑法》第357条,我国毒品范围的确定采用的是“部分列举+抽象定义”模式。这种毒品范围确定模式在适用中容易产生两个方面问题:一是涉非列管物质犯罪认定问题;二是涉自用或医用型麻醉药品和精神药品犯罪认定问题。出现这些问题的根源在于对“毒品范围”的形式化理解和适用,不能满足新型毒品犯罪的治理需求。实质刑法观以法益保护为目的,对犯罪构成要件进行实质解释,更契合新形势下毒品犯罪治理的需要。因此,在实质刑法观视野下,毒品范围认定不应只局限于国家规定管制、成瘾性以及“麻醉药品和精神药品”三要素,还应当考量涉案成瘾物质的现实社会危害性。具体路径包括:适当调整毒品范围确定模式;对非列管物质犯罪、自用或医用型麻精药品犯罪进行实质解释;做好毒品犯罪治理的行刑衔接。

Due to the widespread use of nanocarbon materials(NCMs),more researchers are studying their tribological performances.In this work,the tribological behaviors of the following five types of NCMs with different geometric shapes were evaluated in a novel oil‐in‐water system:spherical fullerenes(C60,0D),tubular multi‐walled carbon nanotubes(MWCNT,1D),sheet graphene oxide(GO,2D),sheet graphene oxide derivative(Oct‐O‐GO,2D),and lamellar graphite(G,3D).Among these,GO with two types of oxidation degrees,i.e.,GO(1),GO(2),and Oct‐O‐GO(1)were synthesized and characterized using Fourier‐transform infrared spectroscopy,Raman spectroscopy,x‐ray diffraction,thermogravimetric analysis,scanning electron microscopy,and contact angle measurements.The load‐carrying capacity of the NCM emulsions were evaluated using a four‐ball test machine,and the lubrication performances were investigated using a high‐frequency reciprocating friction and wear tester with a sliding distance of 1,800 mm under different loads(50 N and 100 N)at 0.5 Hz.The results revealed that the Oct‐O‐GO(1)emulsion exhibited the best load‐carrying capacity,and the best friction‐reducing and anti‐wear properties compared to other emulsions.Moreover,the anti‐wear advantage was more prominent under high load conditions,whereas the other emulsions exhibited a certain degree of abrasive or adhesive wear.The lubrication mechanism was determined through the analysis of worn surfaces using scanning electron microscopy/energy‐dispersive x‐ray spectroscopy,micro‐Raman spectroscopy,and x‐ray photoelectron spectroscopy.The results revealed that during frictional sliding,the ingredients in the emulsion can absorb and react with the freshly exposed metal surface to form surface‐active films to protect the surfaces from abrasion.Moreover,it was found that the higher the amount of ingredients that contain alkyl and O‐H/C=O,the better was the lubrication performance in addition to an increase in the carbon residue in the tribofilm generated on the meal surface.

As known to all,China has witnessed remarkable development in addition to its effective implementation of the“double reduction”policy.Under such circumstance,the piano has drawn more interest and parental affection as a vital course that may improve students’all-round qualities.While piano education is gaining momentum,the country has raised the requirements for the piano teacher workforce in terms of their professional qualities.Under the background of promoting quality-oriented education nationwide,piano education in Chinese vocational colleges of art has garnered more attention.In contrast to applied piano instruction,which has received wide recognition and promotion,the traditional elite private teaching model targeted at nurturing pianists has more than ever failed to meet societal demands.The majority of graduates from vocational colleges of art seem to be unable to apply what they have learned.They are unable to compose accompaniment for simple songs,write piano music,provide piano accompaniment for singers,or sing while playing the piano.As a result,they fall short of living up to the expectations of piano teaching and meeting the needs of music teacher employment in primary and secondary schools.The development of“Xindi Applied Piano Pedagogy”can effectively address the aforementioned problems.As piano teachers,the authors experimented with Xindi Applied Piano Pedagogy to teach singing while playing the piano to first-year students at Fujian Vocational College of Art.A measurement table was used to measure the differences in various musical abilities of those students after the experiment,statistical analysis of the data was performed,and the preliminary results were obtained.The results showed that training in Applied Piano Singing while Playing led to a noticeable improvement in students’musical literacy,harmonic hearing,singing while playing beloved songs,and other abilities.Xindi Applied Piano Pedagogy is guided by the philosophy of talent cultivation,featuring“application,theories,and practice.”It c

Xindi Applied Piano Pedagogy(XAPP)is one of the key achievements of Chinese music education reform in recent years,reflecting the booming of piano education in China.Twenty years after its establishment,the pedagogy has been widely accepted by society.Based on the PDCA(plan-do-check-act)cycle,the paper studies XAPP in relation to teaching quality management,hoping to achieve quality teaching results by improving teaching models and quality.In order to investigate the XAPP teaching process,a closed-loop management on XAPP’s teaching quality is formed,and the questions are divided into different modules:teaching team building,curriculum design,course in effect,teaching materials selection,teacher assessment and rectification,customer satisfaction survey,as well as teaching evaluation and feedback.The application of the PDCA cycle in XAPP’s teaching quality management is then analyzed,with an aim to optimize applied piano teaching management and improve XAPP’s teaching system,curriculum design,teaching materials,and theoretical framework.This paper also studies XAPP from a management perspective,which not only promotes the development of music education,but also expands the research field of music education management.

Background Non-suicidal self-injury (NSSI) behaviour is very common among adolescents. Its prevalence and behavioural characteristics may vary according to regional and cultural differences. Investigation of NSSI locations and diagnosis of adolescents with NSSI are relatively lacking in China. Aims The study objective was to determine the prevalence and features of NSSI among middle school students in Shanghai. Methods The participants were from grade 6 to 8 selected from three junior schools in Jing’an District. Consenting students completed the Ottawa Self-Injury Inventory to determine the prevalence and characteristics of NSSI. Those who indicated NSSI within the past month were administered the Mini-International Neuropsychiatric Interview for Children and Adolescents to assess for emotional disorders. Result The result shows 510 participants (21.7%;mean age 13.51 (0.97) years old;56.7% female) reported at least one instance of NSSI during the previous 12 months. NSSI was significantly more common in girls than boys (24.9% vs 18.5%;χ^2=14.03, p=0.00). Commonly reported reasons for NSSI were for internal and external emotion regulation (87.9%, 82.3%) and social influence (57.8%). Anxiety disorders were the most common (28.9%) disorder associated with NSSI. Conclusion The rate of NSSI of middle school students in Shanghai inner bound is similar to those reported in North American and European youth. It is essential that school mental health professionals are aware of how to manage NSSI within the school setting.

背景机会性输卵管切除术(OS)可以作为卵巢癌(OC)的一级预防手段,但由于卵巢与输卵管拥有同源血供系统,OS可能会引起卵巢功能的损害,从而增加卵巢老化和更年期提前的风险。目的基于GRADE证据分级系统,评价OS对卵巢储备的短期影响。方法于2022年9月,检索中国知网、万方数据知识服务平台、维普网、PubMed、Web of Science、Scopus,获取评估OS对卵巢储备短期影响的文献,检索时限均为建库至2022-09-10。由2名研究者独立筛选文献并提取数据,使用Jadad量表评价文献质量,Stata 17.0软件用于数据处理与荟萃分析,GRADEpro 3.2软件用于评估荟萃分析结果的证据质量。结果共纳入9项随机对照试验(RCT),包含482例患者,其中OS组238例、non-OS组244例。Jadad风险评估量表结果显示所纳入的RCT均为高质量文献。荟萃分析结果表明:相对于non-OS组,OS组抗苗勒氏激素(AMH)(WMD=-0.07,95%CI=-0.28~0.13,P=0.13)、卵泡刺激素(FSH)(WMD=-0.03,95%CI=-1.65~1.59,P=0.24)、黄体生成素(LH)(WMD=-0.39,95%CI=-1.62~0.83,P=0.08)、雌二醇(E2)(WMD=3.08,95%CI=-4.26~10.43,P=0.35)手术前后的变化差异无统计学意义(P>0.05)。GRADEpro软件对荟萃分析的结果显示,AMH的研究为高质量证据,FSH的研究为中等质量证据,E2和LH的研究为低质量证据。结论在短期内因良性疾病接受OS的未绝经女性的卵巢储备功能指标与未接受OS的女性无明显差异。已完成生育的绝经前女性通过OS来预防OC是合理的,但是这个结论仍有待于更长随访时间、设计更严谨且样本量更大的RCT来验证。

Triboelectric nanogenerators(TENGs)have been developed rapidly into an efficient wind energy collection equipment.Reducing the frictionwear and energy loss in breeze energy collection is a research direction worthy of attention.Herein,a flutter-effect-based triboelectricnanogen erator(FE-TENG)is designed to collect the breeze energy at low wind speed from arbitrary directions.Distinguishing from previouswind-driven TENGs,the wind-driven part of this device is separated from the TENG units,which not only avoids the wear of friction layerscaused by direct wind contact but also reduces the energy loss,therefore,relatively stable electric outputs are obtained with Voc-281 V,Isc-13.4μA,Qsc-143 nC,and output power-4 mW at the wind speed of 4.5 m/s,respectively.In addition,a real-time wind speed monitoringsystem based on LabVIEW software with high sen sitivity and fast response to wind is achieved relying on the excellent linear relation shipbetween wind speed and electrical output signal.Furthermore,it has been successfully applied as power sources for portable electronics,about 170 commercial light-emitting devices(LEDs)are lighted and a digital watch is successfully driven at the wind speed of 2.9 m/s.This worknot only provides a new structure and idea for the future collection of clean and sustainable breeze energy from arbitrary directions but also hasgreat potential in the field of self-powered systems.
