Understanding the habitat shifting pattern is a prerequisite for implementing in situ conservation of migratory species.Spotted seals(Phoca largha)inhabiting the Yellow Sea ecoregion(YSE)comprise a small population with independent genes and represent a charismatic flagship species in this region.However,this population has declined by 80%since the 1940s,and increased support from the countries around the YSE is urgently needed to address the potential local extinction risk.A time-series niche model and life-history weighted systematic conservation planning were designed on the basis of a satellite beacon tracking survey(2010–2020)of the YSE population.The results showed clustering and spreading shifting patterns during the breeding and migratory seasons,respectively.The closed-loop migration route formed in the YSE indicated that this population might be geographically isolated from populations in other breeding areas around the world.The conservation priority area(CPA),with an area of 19632 km^(2)(3.58%of the total YSE area),was the most effective response to the potential in situ risk.However,nearly 80%of the CPA was exposed outside the existing marine protected areas(MPAs).Future establishment of MPAs in China should strategically consider the conservation gap identified herein,and it is recommended for Korea’s closed fishing season to be spatially set in the western Korean Peninsula from May to August.This study also exemplified that the lack of temporal information would lead to the dislocation of niche modeling for migratory species represented by spotted seals.Attention should be paid to protecting small and migratory populations in marine biodiversity conservation planning.

The Laizhou Bay(LB)represents a substantial ecological area that is vulnerable to human activities and confronts diverse environmental challenges.This study provides a comprehensive characterization of nutrients,petroleum,heavy metals,and phytoplankton community structure across seven distinct areas in LB.The results indicate relatively high concentrations of NO_(2)-N,SiO_(4)-Si,and NO_(3)-N in the Southwest Laizhou Bay(SWLB)and Huanghe River Estuary(HRE).In contrast,the East Laizhou bay(ELB)and the North of Huanghe River Estuary(NHRE)exhibit the highest concentrations of heavy metals(As,Cr and Hg).The areas with high phytoplankton density and community diversity are mainly located in the SWLB.After adjusting for basic environmental factors,phytoplankton density and Margalef richness index D are significantly associated with nutrients(NO_(3)-N,NO_(2)-N,NH_(4)-N,SiO_(4)-Si),and heavy metal(Cr)concentrations.We highlight that,in addition to Xiaoqinghe River,nutrients brought by the Mihe River in the SWLB and heavy metal(Cr)pollution in the ELB resulting from industrial and mining activities along the coast significantly influence phytoplankton growth and community structure.Therefore,it is recommended that more monitoring and management efforts be focused on these regions in the future.

Achieving land degradation neutrality(LDN)worldwide is a significant target of the Sustainable Development Goal(SDG15.3).Inner Mongolia,as a typical dryland region in northern China,has carried out several large-scale ecological restoration programs to combat land degradation.However,there is a lack of comprehensive assess-ment of its land degradation situation after ecological programs implementation,which is of great significance to supporting SDG15.3 in China.This study analyzed the land degradation situation using the improved SDG15.3.1 calculation framework based on fine resolution data in Inner Mongolia from 2000 to 2020,and finally compre-hensively evaluated the land status of the whole region and those subject to ecological programs.The results show that net land restoration proportion of various ecological project regions and whole region continues to increase.The scope of the Grain for Green Program(GGP)had the largest proportion of net land restoration while the Natural Reserve Program(NRP)had the lowest proportion from 2000 to 2020.The net land restoration area of Inner Mongolia during 2000-2010 and 2010-2020 was 35,800 km 2 and 65,300 km 2,respectively.Overall,Inner Mongolia has achieved statistically zero growth in land degradation under the governance of ecological restora-tion programs.Therefore,reasonable planning,well monitoring,and timely assessment of ecological restoration programs are crucial to support SDG15.3.

The most common subtype of lung cancer is non-small cell lung cancer(NSCLC), which has a poor prognosis and seriously threatens the health of human beings. The multidisciplinary comprehensive treatment model has gradually become the mainstream of NSCLC treatment. Traditional Chinese medicine(TCM) can be used effectively either as an adjunctive therapy or alone throughout the NSCLC therapy,which has a significant impact on survival, quality of life, and reduction of toxicity. Therefore, this paper reviewed the theoretical basis, the latest clinical application, and combined treatment mechanisms in order to explore the advantage stage of TCM treatment and the synergistic therapeutic mechanisms.

Regional coordinated ecological development is a new form of regional coordinated development that aims to construct an ecological civilization in the“new normal”period.The coordinated ecological development of the Beijing-Tianjin-Hebei(BTH)region is especially significant because this region is leading the overall coordinated development and reform in China.Based on complex system theory,synergetics,and the ecological civilization and green development ideas of the“new normal”period,we constructed a regional ecological synergy measurement model that scientifically evaluates the dynamic evolution of the BTH ecological synergy level from 2006 to 2018.Using an econometric model,we also analyzed the welfare effect and the regional heterogeneity of ecological synergy in regional development.First,it was found that in general,the degree of ecological synergy in BTH increased yearly up to 2018 with a strong development trend.The speed of ecological synergy in the Tianjin-Hebei and Beijing-Hebei subsystems was accelerating during that period,but the development potential of the ecological synergy in Beijing-Tianjin was insufficient and slow-growing.Second,whereas Beijing had entered the stage of moderate coordinated ecological development,Tianjin and Hebei remained in the low level of coordinated development;moreover,the coordinated development was unstable.The uneven development of the internal subsystems in BTH restricted the development of the cooperative effect and the overall development of the region.Third,improving the degree of ecological synergy significantly benefited the social and economic welfare in BTH.Finally,the welfare effect of the degree of ecological synergy showed a significant regional heterogeneity,being significantly higher in Tianjin and Hebei than in Beijing.This result indicates that improving the ecological synergy can narrow the development gaps between Tianjin,Hebei,and Beijing.To further improve the level of regional ecological synergy,we should innovate the coordinated model of regional d

China has banned harvesting organs from executed prisoners since January 1st, 2015, making voluntary donation the only legitimate venue for organ transplant. It is a critical move to settle all the controversies about China＇s organ transplant process by making a loud and strong statement worldwide that the Chinese government respects human rights and is streamlining its organ transplant process to conform with internationally accepted standards on organ transplantation. This regulation removes one major obstacle of organ transplant in China; however, China still faces the other maior obstacle of critical organ shortage.

1.Introduction Nonaqueous Li–O2 batteries have attracted considerable research interest due to their high energy density to replace the present power Liion batteries possibly[1–3].However,the fierce challenge in Li–O2 batteries is how to make it work in real air atmosphere,and explore the roles of H2O and CO2,which can adapt to a wider range of applications.With the rapid development,energy consumption is increasing and the amount of CO2 produced by the utilization of fossil fuels worldwide reaches thousands of tons per year,which aggravates the global“greenhouse effect”.It is the demand for social and economic development to combine the reduction of“greenhouse effect”with energy storage,and the utilization of CO2 in rechargeable batteries could skillfully realize this target[4,5].Among various battery systems,Li/Na–CO2 batteries have attracted rapidly increasing attention in the past a few years.However,Li/Na–CO2 batteries still suffer from insufficient electrochemical performance and ambiguous reaction mechanisms.To this end,substantial efforts and innovative directions are required to ameliorate the current predicament for Li/Na–CO2 batteries.

Synthesis and catalytic performance of macroporous La1-xCexCoO3 perovskite oxide catalysts with high oxygen mobility for catalytic combustion of soot

引用

Journal of Rare Earths 2020年第6期38卷 584-593页

作者： Jiachen Sun Zhen zhao Yazhao Li Xuehua Yu linlin zhao Jianmei Li Yuechang Wei Jian Liu State Key Laboratory of Heavy Oil Processing China University of Petroleum-BeijingBeijing 102249China Institute of Catalysis for Energy and Environment College of Chemistry and Chemical EngineeringShenyang Normal UniversityShenyang 110034China

The disordered macroporous-mesoporous La1-xCexCoO3 catalysts were prepared by complexcombustion method with ethylene glycol as complexing agent at relatively low calcination temperature.The samples were characterized by means of X-ray diffraction,N2 adsorption-ndash;desorption,Xray photoelectron spectroscopy,transmission electron microscopy,hydrogen temperature-programmed reduction and soot temperature-programmed reduction,and so on.The results show that the use of complexing agent and relatively low calcination temperature increase the specific surface area of the catalyst and have abundant pore structure.The Ce ions introduced into lattice of LaCoO3 mainly exist in the form of tetravalent.At the same time,Ce ions enhance the redox performance of the catalyst and the mobility of active oxygen species,which enhances the catalytic activity of the catalyst for soot combustion.The results of activity test show that La0.9Ce0.1CoO3 catalyst exhibits the highest activity in the absence of NO and NO2,and its T10,T50 and T90 are 371,444,and 497℃,respectively.At the same time,a possible reaction mechanism is proposed in this study based on the turnover frequency(TOF) calculated by isothermal anaerobic titrations,XPS and XRD results.
