Quasi-Solid-State Ion-Conducting Arrays Composite Electrolytes with Fast Ion Transport Vertical-Aligned Interfaces for All-Weather Practical Lithium-Metal Batteries

The rapid improvement in the gel polymer electrolytes(GPEs)with high ionic conductivity brought it closer to practical applications in solid-state Li-metal batteries.The combination of solvent and polymer enables quasi-liquid fast ion transport in the GPEs.However,different ion transport capacity between solvent and polymer will cause local nonuniform Li+distribution,leading to severe dendrite growth.In addition,the poor thermal stability of the solvent also limits the operating-temperature window of the electrolytes.Optimizing the ion transport environment and enhancing the thermal stability are two major challenges that hinder the application of GPEs.Here,a strategy by introducing ion-conducting arrays(ICA)is created by vertical-aligned montmorillonite into GPE.Rapid ion transport on the ICA was demonstrated by 6Li solid-state nuclear magnetic resonance and synchrotron X-ray diffraction,combined with computer simulations to visualize the transport process.Compared with conventional randomly dispersed fillers,ICA provides continuous interfaces to regulate the ion transport environment and enhances the tolerance of GPEs to extreme temperatures.Therefore,GPE/ICA exhibits high room-temperature ionic conductivity(1.08 mS cm^(−1))and long-term stable Li deposition/stripping cycles(>1000 h).As a final proof,Li||GPE/ICA||LiFePO_(4) cells exhibit excellent cycle performance at wide temperature range(from 0 to 60°C),which shows a promising path toward all-weather practical solid-state batteries.

Ultra-Stable and Durable Piezoelectric Nanogenerator with All-Weather Service Capability Based on N Doped 4H-SiC Nanohole Arrays

Ultra-stable piezoelectric nanogenerator(PENG)driven by environmental actuation sources with all-weather service capability is highly desirable.Here,the PENG based on N doped 4H-SiC nanohole arrays(NHAs)is proposed to harvest ambient energy under low/high temperature and relative humidity(RH)conditions.Finite element method simulation of N doped 4H-SiC NHAs in compression mode is developed to evaluate the relationship between nanohole diameter and piezoelectric performance.The density of short circuit current of the assembled PENG reaches 313 nA cm^(-2),which is 1.57 times the output of PENG based on N doped 4H-SiC nanowire arrays.The enhancement can be attributed to the existence of nanohole sidewalls in NHAs.All-weather service capability of the PENG is verified after being treated at-80/80℃and 0%/100%RH for 50 days.The PENG is promising to be widely used in practice worldwide to harvest biomechanical energy and mechanical energy.

Management of Immediate Postpartum Hemorrhage at the University Hospital Center of the Sino-Central African Friendship

Introduction: Immediate postpartum hemorrhages constitute a frequent maternal complication and remain at the forefront of maternal death in our countries. Objective: Contribute to improving the management of immediate postpartum hemorrhage in our context with a view to reducing maternal mortality. Patients and Methods: We conducted a retrospective descriptive and analytical study over a period of 12 months from January 1st to December 31st 2020. Results: We collected a total of 109 files on a total of 4360 deliveries. The frequency of postpartum haemorrhages was of the order of 2.5%. The most represented age group was between 20 and 24 years old. Pauciparas represented the majority of our study population. 64.5% of patients were uneducated. These hemorrhages occurred in patients who often gave birth outside the department with 63.8%. The main causes of postpartum hemorrhage were cervical tears (51.2%) and partial placental retention (30.7%). The majority of these deliveries (48.8%) were carried out by midwives followed by assistant midwives (33.2%). Active management of the third period of delivery was systematic and immediate followed by the valve examination completed by the infusion of oxytocin in case of uterine atony, tranexamic acid ans misoprostol intrarectally. In the event of persistent hemorrhage, suture of the cervical lesions, ligation of the cervical vessels or even laparotomy either for the selective ligation of the blood vessels or for the hysterectomy for hemostasis were practiced. We do not have a Nalador, nor a Bakry balloon, nor an Interventional Radiology service for embolization of the uterine arteries. We deplore 1.3% of deaths from afibrinogenemia. Conclusion: The frequency of immediate postpartum hemorrhages is lower in our health facility. This is due to the rapid handling of cases. Improving the quality of services offered to women during childbirth can further help reduce the frequency of these hemorrhages.

Clandestine Abortions and Its Complications at the University Hospital Center of the Sino-Central African Friendship

Introduction: In developed countries in general and particularly in the Central African Republic, clandestine abortions constitute a real health problem. The aim of our work was to study the method of carrying out clandestine abortions, to describe the profile of the providers and the complications that result from it. Patients and Methods: This was a descriptive cross-sectional study of patients hospitalized at the University Hospital Center for Sino-Central African Friendship (CHUASC) from 2015 to 2019 on 236 cases. Results: We identified a total of 254 patients for 8039 live births in the same period, a frequency of 3.16%. The age of the patients was between 15 years old and 48 years old with an average of 25 years old. Singles accounted for 42.5%. Induced abortions were more performed among students (32.6%) and the unemployed 53.6%. Contraception was used in 11.5% of cases. The methods used were numerous: misoprostol (32%), the traditional method (18%), the mechanical method (50%). In this method, we note the dilation of the cervix by the cassava stem;Hegar’s candles;the probes, which are infusion tubes cut and introduced into the cervix, of which 2 cases had escaped at the level of the uterine muscles and emerged under the skin at the pubis part two years later. The practice of induced abortions in our series was done by medical students in 37.3% followed by unqualified staff in 49.7%. It took place either at home or in centers managed by Non-Governmental Organizations. The aseptic conditions were not perfect. Some patients (43.2%) were aware of the ensuing complications. All complications were present: hemorrhage (60.7%), pelviperitonitis (23.6%), uterine perforation (6.6%), peritonitis (2.8%) and death (2%) related to sepsis. Conclusion: Clandestine abortion remains a real health problem for young Central African women.

创意越轨:双元领导影响员工创意实施的“非法”路径研究

基于紧张理论和资源保存理论,提出双元领导在同事职场友谊边界下通过创意越轨作用于创意实施的“非法”路径,并对5家国有企业管理者和员工进行问卷调查,采用多项式回归和块变量分析法进行假设验证。结果发现:双元领导的不一致性会带来更多结构紧张,员工创意越轨行为随之增加,而双元领导一致性有利于员工开展更多创意实施;创意越轨在双元领导与创意实施间发挥部分中介作用;同事职场友谊存在调节效应,高同事职场友谊条件下创意越轨的中介效应显著,反之,低同事职场友谊下创意越轨不存在显著中介效应。

利益、品格还是自成一类:亚里士多德论政治友爱

亚里士多德在《尼各马可伦理学》和《欧德伦理学》中讨论了政治友爱(homonia,或译为“同心”),关于这种友爱在亚里士多德的友爱三分法中所处的位置,学术界存在持续的争论。主要争议在于,这种友爱是利益型友爱、品格型友爱,还是一种不同于三种基本友爱类型的独立类型,或仅仅是好意而非友爱。亚里士多德的文本中有充分的证据表明,政治友爱属于利益型友爱。相反的观点或多或少地误解了亚里士多德对政治友爱的定位。尽管政治友爱被归类为利益型友爱,但这并不妨碍它在政治共同体的塑造中扮演至关重要的角色,也不妨碍在此基础上发展出品格型的友爱。亚里士多德的“政治友爱”观念可以延伸到斯多亚学派的“世界公民”思想,体现了两种思想的延续性及斯多亚学派对亚里士多德思想的发展。

中国恩德文化的范畴体系

中国文化是恩德文化,就是以施恩-报恩法则规定人际关系,其中社会的管理者是施恩者,被管理者是受恩者、报恩者。恩德文化在不同的领域建立了不同的伦理范畴。在家庭领域形成了以孝悌为中心的伦理范畴,建构了父慈子孝、兄友弟恭、夫德妻贤的伦理规范。在社会领域形成了以友敬为中心的伦理范畴,建构了尊上恤下、敬老爱幼、朋友互信的伦理规范。在政治领域形成了以忠顺为中心的伦理范畴,建构了君明臣忠、官良民顺的伦理规范。这些范畴都体现了恩德观念,构成了一个完整的中国文化体系。

论李杜交谊及其意义

李白杜甫交谊是重要的文学现象和文化现象,其意义绝不限于普通的人际关系,二人的友谊是中国文学史、文化史上伟大的情谊,是儒家倡导的以义相交的典范。具体而言,李白对杜甫很关心,但与杜甫对李白的盛情相比,李白对杜甫的情谊不够“对等”:在李白交游圈中,杜甫只是他的普通朋友;在杜甫的交友圈中,李白是他一见倾心的人物。杜甫推崇李白的才华和气质,理解李白为诗为人,同情李白的遭遇,甚至为李白申冤,这充分证明李白飘逸人格与绝世才华的巨大魅力。杜甫对李白的推崇、关怀、同情、理解,也反映出杜甫独特的思想素质和精神需求,在杜甫成长过程中发挥了独特的作用,具有重要的思想史和诗史意义。

1936—1945年中共东北党组织与朝鲜革命关系

1936年初,中共东北党组织根据共产国际“七大”精神和中共驻共产国际代表团的指示,提出了更加符合东北朝鲜民族抗日革命特殊性的新的一系列方针政策。在党的正确领导下,东北朝鲜民族共产主义者肩负着“双重革命使命”,在东北抗战中积极发挥重要作用的同时,更加有力地推进了朝鲜国内反日民族独立解放斗争。中国共产党支援和推进朝鲜革命的方针政策主要是以东北党组织及其武装队伍中的朝鲜民族党员、团员和指战员贯彻执行的,在这一过程中形成了以金日成将军为首的朝鲜革命的坚强的领导核心群体。这一段历史是中共东北党组织正确执行无产阶级国际主义原则和抗日民族统一战线政策,树立东方反日民族解放斗争的光辉典范的历程,是东方各国人民并肩战斗、共同争取抗战胜利的伟大历史,也是以生命和鲜血坚实地奠定现代中朝友谊基础的宝贵的历史财富。

“中美友好通商航海条约”清理的“外部性”问题

外交部条约委员会曾根据《中国人民政治协商会议共同纲领》第55条的规定,对1949年之前国民党政府签署的旧条约进行了清理。然而,清理结果并未正式对外公布,导致无论是国际法院还是美国政府等都认为“中美友好通商航海条约”这一旧条约依然“有效”。我国有必要尽快在法律上公开对此旧条约的清理程序,宣布此条约无效,并将清理结果告知国际法院,敦促国际法院适用1971年联合国大会第2758号决议,改变其对“中美友好通商航海条约”的既有立场。
