The effect of self-reactivation on the CO_(2) capture capacity of the spent calcium based sorbent was investigated in a dual-fixed bed reactor.The sampled sorbents from the dual-fixed bed reactor were sent for XRD,SEM and N_2 adsorption analysis to explain the self-reactivation mechanism.The results show that the CaO in the spent sorbent discharged from the calciner absorbs the vapor in the air to form Ca(OH)_(2) and further Ca(OH)_(2)·2 H_(2) O under environmental conditions,during which process the CO_(2) capture capacity of the spent sorbent can be self-reactivated.The microstructure of the spent sorbent is improved by the self-reactivation process,resulting in more porous microstructure,higher BET surface area and pore volume.Compared with the calcined spent sorbent that has experienced 20 cycles,the pore volume and BET surface area are increased by 6.69 times and 56.3% after self-reactivation when φ=170%.The improved microstructure makes it easier for the CO_(2) diffusion and carbonation reaction in the sorbent.Therefore,the CO_(2) capture capacity of the spent sorbent is enhanced by self-reactivation process.A self-reactivation process coupled with calcium looping process was proposed to reuse the discharged spent calcium based sorbent from the calciner.Higher average carbonation conversion and CO_(2) capture efficiency can be achieved when self-reactivated spent sorbent is used as supplementary sorbent in the calciner rather than fresh CaCO_(3) under the same conditions.

Anthocyanins are secondary metabolites induced by environmental stimuli and developmental signals.The positive regulators of anthocyanin biosynthesis have been reported,whereas the anthocyanin repressors have been neglected.Although the signal transduction pathways of gibberellin(GA)and jasmonic acid(JA)and their regulation of anthocyanin biosynthesis have been investigated,the cross-talk between GA and JA and the antagonistic mechanism of regulating anthocyanin biosynthesis remain to be investigated.In this study,we identified the anthocyanin repressor MdbHLH162 in apple and revealed its molecular mechanism of regulating anthocyanin biosynthesis by integrating the GA and JA signals.MdbHLH162 exerted passive repression by interacting with MdbHLH3 and MdbHLH33,which are two recognized positive regulators of anthocyanin biosynthesis.MdbHLH162 negatively regulated anthocyanin biosynthesis by disrupting the formation of the anthocyanin-activated MdMYB1-MdbHLH3/33complexes and weakening transcriptional activation of the anthocyanin biosynthetic genes MdDFR and MdUF3GT by MdbHLH3 and MdbHLH33.The GA repressor MdRGL2a antagonized MdbHLH162-mediated inhibition of anthocyanins by sequestering MdbHLH162 from the MdbHLH162-MdbHLH3/33 complex.The JA repressors MdJAZ1 and MdJAZ2 interfered with the antagonistic regulation of MdbHLH162 by MdRGL2a by titrating the formation of the MdRGL2a-MdbHLH162 complex.Our findings reveal that MdbHLH162 integrates the GA and JA signals to negatively regulate anthocyanin biosynthesis.This study provides new information for discovering more anthocyanin biosynthesis repressors and explores the cross-talk between hormone signals.

Tough elastomers and gels have garnered broad research interest due to their wide-ranging potential applications. However, during the loading and unloading cycles, a clear stress softening behavior can be observed in many material systems, which is also named as the Mullins effect. In this work, we aim to provide a complete review of the Mullins effect in soft yet tough materials, specifically focusing on nanocomposite gels, double-network hydrogels, and multi-network elastomers. We first revisit the experimental observations for these soft materials. We then discuss the recent developments of constitutive models, emphasizing novel developments in the damage mechanisms or network representations. Some phenomenological models will also be briefly introduced. Particular attention is then placed on the anisotropic and multiaxial modeling aspects. It is demonstrated that most of the existing models fail to accurately predict the multiaxial data, posing a significant challenge for developing future anisotropic models tailored for tough gels and elastomers.

On 22 May 2021,the Maduo Earthquake occurred on a branch fault of the East Kunlun fault in the Bayan Har Block,which provides opportunity to constrain fault geometry and strain accumulation and release for assessment of earthquake hazards.We processed the Sentinal-1A/B SAR images acquired before and after the earthquake,with which we constrained a finite fault model to best fit to the combined data set of downsampled InSAR image and GPS displacements.The inversion indicates that the Maduo event ruptured a 160 km long section striking 286.5°and a dipping 81.39°with rake angle of 4.62°.The model suggests three compact rupture areas with the slip amplitude exceeding 4 m on the main rupture section and the largest slip region is in the east of the epicenter with a slip of approximately 4.6 m below the surface,in a good agreement with the field geological survey.The total geodetic moment is 1.67×10^(20) N·m equivalent to Mw7.44,slightly larger than estimate of the USGS.

As industrialization accelerates and the amount of hazardous waste generated gradually increases,the means of disposal of hazardous waste is of increasing concern.In this paper,a 40 t/d counter-fow rotary kiln incineration system owned by a Jiangsu environmental protection company was researched.The software Aspen Plus was used to build the mixed pyrolysis model and the software Fluent was used to build the computational fuid dynamics model of the incineration system.The infuence of the calorifc value of the hazardous waste,the operating temperature and the air supply on the operational efectiveness of the incineration system were analyzed by varying the simulation conditions.The results show that the SO_(x)and NO_(x)content of the product is lower when the operating temperature is above 800℃.The incineration system could only operate above 800℃when the calorifc value of the hazardous waste is not less than 1500 kcal/kg.The incineration system operated best at a primary air velocity of 1.5 m/s.The simulation results in this paper serve as a guide for the operation of counter-fow rotary kiln incineration systems.

Co-pyrolysis of lignin and waste plastics,for example polyethylene(PE),has been studied,but related reports are basically on condition optimizations.This study revealed a new perspective on PE-promoted lignin pyrolysis to phenolic monomers with mass transfer and radical explanation.Lignin and PE were first pyrolyzed individually to identify pyrolysis characteristics,pyrolytic products,as well as the suitable copyrolysis temperature.Then,co-pyrolysis of blended lignin/PE with various ratios was investigated.Yields of lignin products reached the maximum under lignin/PE ratio of 1:1,but blended approach always inhibited the production of lignin phenols.This resulted from the poor mass transfer and interactions between lignin and PE,in which PE pyrolysates could easily escape from the particle gaps.While in layered approach,PE pyrolysates had to pass through the lignin layer which contributed to the good interactions with lignin pyrolysis intermediates,thus the yields of lignin-derived products were significantly improved.Interactions between lignin and PE(or their pyrolysates)were mainly radical quenching reactions,and X-ray photoelectron spectrum(XPS)and electron paramagnetic resonance(EPR)of pyrolytic chars were conducted to verify these interactions controlled by mass transfer.The percentage of C]C(sp^(2))and concentration of organic stable radicals in layered lignin/PE char were both the lowest compared with those in blended lignin/PE and lignin char,indicating the stabilization of lignin-derived radicals by PE pyrolysates.Moreover,the spin concentration of radicals in the char from layered char/PE was lower than that in lignin char,which further affirmed the quenching of radicals by PE in the layered co-pyrolysis mode.

本文的主要研究目的是通过对马来西亚中医的历史发展和现状,包括教育、协会、政策、临床现状的调查和分析,希望可以帮助国内的中医界了解东南亚中医药的发展情况,促进国内中医界自身的更加繁荣。同时也可以为中医药在全世界的推广发展提供借鉴。尤其是关于中医教育方面,在临床教育上其他国家可以向马来西亚学习。与中国的高校联合办学,可以帮助提高学生的临床经验。而在政策方面,目前海外许多其他国家尚未立法,而马来西亚的卫生部下属传统与补充疗法部门的统一管理可以为所有西医为主流医学的海外国家提供可供参考的目标。还希望能帮助马来西亚各个族群更深入的了解中医药的益处,中医界能够与其他的传统与补充疗法一起更好的为马来西亚各族人民服务。希望可以促进全世界的中医界的相互学习交流。设计了对针灸师的调查问卷,研究针灸方面的临床情况,共发放问卷调查表二十份,研究了针灸师们的工作时间、病人数目、病种、针灸和其他操作手法、收费等情况。研究结果:中医药传入马来西亚从十四世纪郑和下西洋开始,但是直到十九、二十世纪由于华人华侨增多,才开始加速发展。一些中医药协会团体和教育机构相继成立,到2004年成立传统与补充疗法部门(T&CMD)进行专门管理。中医教育方面,共有九所高校提供中医药全日制高等教育课程,大部分都使用英文和中文双语授课,且课程都包含了部分西医学与当地文化的内容。中医学部分很多学校都注重中医经典比如黄帝内经、金匮要略、温病学、伤寒论、子午流注等的学习。所有的高校都有自己的临床实习基地,也都与中国的一些高校合作,可以将学生派往中国学习更多的临床经验。在马来西亚注册成为中医师或者针灸师需要有五年制中医本科学历或三年制中医针灸专业学历。根据卫生部规定,外国医师注册还有年龄限制30岁以上和必须要有5年以上工作经验,还要求同时在马来西亚授课和进行义诊。这样保证进入马来西亚工作的外国中医师拥有足够的经验,且能帮助促进马来西亚的学术交流和中医进步。T&CMD在全国十四所医院内设立了针灸科室,主要用以治疗慢性疼痛和中风。在4所医院内设立了中草药科室,主要是作为辅助疗法治疗癌症。针灸和草药进入公立医院使更多的当地人了解到中医的优势与益处,极大地推动了中医的发展。而在民间则是中药、针灸、推拿、拔罐、刮痧等百花齐放,病种也是多种多样,普通的肌肉关节疼痛到内科中风妇科痛经等都有,而且为了保持疗效,使用的针灸手法也不只是传统体针,还包含了腹针、董氏奇穴针法等。在马来西亚的许多医师都是定期前往偏远地区或者土著族群里进行义诊,推广发扬中医。这方面是值得我们所有人学习的。中医药的科研主要是T&CMD拨款和推动,相继进行了一些关于针灸和草药的临床研究,暂时还没有基础研究。

Induced circularly polarized luminescence of perovskite nanocrystals by self-assembly chiral gel

2012 Genomic Analysis of Diseases Conference

作者： Professor Rui XIAO Inner Mongolia Medical University Inner Mongolia Autonomous Region China

＜正＞The ATP/GTP binding protein 1（Agtpbp1） was known to be associated with neuronal differentiation and regeneration.In Purkinje cell degeneration（pcd） mice,mutated Agtpbp1 causes specific neuronal populations degeneration,including Purkinje neurons in the cerebellum,photoreceptors in the retina and mitral cells in the olfactory bulb.Snapin,a ubiquitous protein known to associate with SNARE complex,has been implicated in the neurotransmission and dendrite patterning.Here,we identified that Snapin is a binding partner of Agtpbpl using yeast two-hybrid screen of a mouse brain cDNA library. Co-immunoprecipitation experiment verified the interaction between Agtpbp1 and Snapin,indicating that Agtpbpl participates with the SNARE machinery in the mouse brain.Confocal microscopic analysis showed colocalization in both the cytoplasm and plasma membrane.In addition,overexpressed Agtpbpl regulates Snapin mRNA expression level in vitro.We conclude that Snapin,interacting with Agtpbpl,plays important role in the neuronal differentiation.

Perovskites nanocrystals(NCs)with circularly polarized light(CPL)activity have drawn much attention due to the fascinating photoelectric properties of perovskite NCs as well as the abundant applications of CPL in three-dimensional(3D)displays,nonlinear optics,spintronics devices,CPL lasers,and so on.Herein,bio-inspired by life,we designed and synthesized a simple amphiphilic molecule which could self-assemble into chiral gel with helix chirality in non-polar solvents.Through co-assembly of the CsPbX3 NCs with the chiral gel,CPL at the first excitation band of CsPbX3 NCs is induced in the whole visible spectrum with a maximum glum of 8.2×10−3.The induced CPL arises from the selective CPL-absorption of the CsPbX3 NCs’luminesce by the chiral gel,which provides a facile and practical approach to induce CPL in perovskite NCs and other nanocrystals.
