| 1 | Reduced interferon antagonism but similar drug sensitivity in Omicron variant compared to Delta variant of SARS-CoV-2 isolates显示文摘Dear Editor,Omicron(B.1.1.529),is a heavily mutated and highly contagious SARS-CoV-2 variant,which is currently causing large outbreaks in many countries.Protection provided by current vaccines is substantially reduced against Omicron.1,2 Moreover,many immunocompromised individuals cannot effectively be protected by vaccines.3 Hence,antiviral therapies will be essential to protect the most vulnerable individuals from severe COVID-19. | Denisa Bojkova Marek Widera Sandra Ciesek Mark N.Wass Martin Michaelis Jindrich Cinatl Jr | 2022 | Cell Research2022,32,3: | 10 |
| 2 | 巨桉(Eucalyptus grandis)植被和其相邻的山地雨林中土壤营养的评价(英文)显示文摘研究评价巨桉(Eucalyptus grandis)植被和其相邻的山地雨林中土壤营养状况。在研究地建立了20个样方,每个小样方为20mx20m。在每个小样方内对土壤进行5个样点的采样(4角和中心点)。把每个小样方的不同点采集的土样进行混合,并独立放置。分析结果表明,巨桉植被和其相邻的山地雨林中土壤指标(全N、有效P、可交换性K、Ca和Mg含量),pH值以及全碳含量)没有明显的变化。但两种林地土壤中的粘土颗粒和可交换性N含量有明显的变化。与巨桉植被相邻的山地雨林中土壤指标比较表明,巨桉植被有提高土壤营养和全碳含量的作用。 | Shiferaw Alem Tadesse Woldemariam Jindrich Pavlis | 2010 | Journal of Forestry Research2010,21,4: | 3 |
| 3 | The role of carbonate-fluoride melt immiscibility in shallow REE deposit evolution显示文摘The Lugiin Gol nepheline syenite intrusion, Mongolia, hosts a range of carbonatite dikes mineralized in rare-earth elements(REE). Both carbonatites and nepheline syenite-fluorite-calcite veinlets are host to a previously unreported macroscale texture involving pseudo-graphic intergrowths of fluorite and calcite. The inclusions within calcite occur as either pure fluorite, with associated REE minerals within the surrounding calcite, or as mixed calcite-fluorite inclusions, with associated zirconosilicate minerals. Consideration of the nature of the texture, and the proportions of fluorite and calcite present(~29 and 71 mol%,respectively), indicates that these textures most likely formed either through the immiscible separation of carbonate and fluoride melts, or from cotectic crystallization of a carbonatefluoride melt. Laser ablation ICP-MS analyses show the pure fluorite inclusions to be depleted in REE relative to the calcite. A model is proposed, in which a carbonate-fluoride melt phase enriched in Zr and the REE, separated from a phonolitic melt, and then either unmixed or underwent cotectic crystallization to generate an REE-rich carbonate melt and an REE-poor fluoride phase. The separation of the fluoride phase(either solid or melt) may have contributed to the enrichment of the carbonate melt in REE, and ultimately its saturation with REE minerals. Previous data have suggested that carbonate melts separated from silicate melts are relatively depleted in the REE, and thus melt immiscibility cannot result in the formation of REE-enriched carbonatites. The observations presented here provide a mechanism by which this could occur, as under either model the textures imply initial separation of a mixed carbonate-fluoride melt from a silicate magma. The separation of an REEenriched carbonate-fluoride melt from phonolitic magma is a hitherto unrecognized mechanism for REE-enrichment in carbonatites, and may play an important role in the formation of shallow magmatic REE deposits. | Jindrich Kynicky Martin P.Smith Wenlei Song Anton R.Chakhmouradian Cheng Xu Antonin Kopriva Michaela Vasinova Galiova Martin Brtnicky | 2019 | Geoscience Frontiers2019,10,2: | 3 |
| 4 | 华北克拉通丰镇碳酸岩中榴辉岩捕虏体岩石学研究:现今板块体制古元古代开始启动证据显示文摘关于现今板块构造体制何时启动是目前地球科学研究的焦点问题。本文在原报道的古元古代丰镇火成碳酸岩中发现的榴辉岩捕虏体基础上,开展了详细的岩石学研究。该榴辉岩捕虏体分为两种类型:即相对富石榴石的Fz-2和贫石榴石的Fz-16,它们产于同一地点,且具有相同的矿物成分和结构构造特征。Xu et al.(2018)的研究表明该捕虏体具有1839±26Ma和1766±7Ma的独居石U-Th-Pb年龄且具有大洋辉长岩原岩的全岩成分特征。本文通过进一步的岩相学研究发现该榴辉岩至少经历了两期变质阶段:M1,角闪石/绿帘石-榴辉岩阶段;M2,硬柱石-榴辉岩阶段。具有放射状裂纹包裹特征的柯英石假象在石榴石变斑晶和基质绿辉石中以包体形式出现。以蓝晶石与黝帘石共存为特征的柱状硬柱石假象,也偶尔以包体形式存在于石榴石中。变斑晶石榴石分为富含包体的核部和比较干净的边部。石榴石从中心到边部具有明显的镁铝榴石含量增加和钙铝榴石含量降低的环带特征,通过相平衡模拟和等值线投图得到其温压范围为2.6~3.7GPa和655~670℃,记录了从M1到M2的近等温增压的进变质过程。通过石榴石边部-绿辉石-蓝晶石-石英的地质温压计计算得到温压条件为3.0GPa、734℃。金红石中的锆含量温度计也给出了相似的温度条件,即在2.6~3.7GPa压力时为601~685℃。石榴石边部的柯石英假象和硬柱石假象支持了M2硬柱石-榴辉岩阶段的存在,这表明丰镇古元古代榴辉岩可能是目前发现的世界上最古老的低温超高压变质岩。同时,我们得到该榴辉岩代表的进变质过程中的地温梯度为216±35℃/GPa,证明至少在~1.8Ga以来代表现今板块构造体制的板块冷俯冲作用就开始启动了。 | 李韵秀 张立飞 许成 KYNICKY Jindrich FEI YingWei | 2021 | 岩石学报2021,37,2: | 2 |
| 5 | Monitoring dioxins and PCBs in eggs as sensitive indicators for environmental pollution and global contaminated sites and recommendations for reducing and controlling releases and exposure显示文摘This review compiles information on PCDD/F-and PCB-contaminated eggs from 20 years of global egg monitoring around emission sources in four continents conducted by the International Pollutants Elimination Network(IPEN)and Arnika as well as a compilation of data from scientific literature.IPEN monitored 127 pooled egg samples including samples from 113 chicken flocks at potential PCDD/F-and PCB-contaminated sites around priority sources listed in the Stockholm Convention(e.g.waste incinerators,metal industries,cement plants,and open burning).99(88%)of pooled egg samples were above the EU maximum limits for PCDD/Fs(2.5 pg PCDD/F-TEQ/g fat)or the sum of PCDD/Fs and dioxinlike PCBs(5 pg PCDD/F-PCB-TEQ/g fat).Children consuming such eggs exceed the tolerable weekly intake(TWI).This demonstrates that close to 90%of these areas were not safe for the production of free-range eggs.Sixteen out of the 113 egg samples(14%)were contaminated above 50 pg TEQ/g fat and exceeded the EU maximum limit more than 10 times.From the 26 pooled egg samples around incinerators 24(92%)exceeded the limit with a mean of 43.1 pg TEQ/g fat(2.6e234 pg TEQ/g).All 21 egg samples around metal industries(4.4e112.6 pg TEQ/g fat)were above limits with mean concentration of 26.0 pg TEQ/g fat.Also all 7 egg samples measured at e-waste recycling sites were above limits(mean 308 pg TEQ/g fat).In 58(51%)pooled egg samples the PCB-TEQ was above 5 pg TEQ/g fat exceeding the EU maximum limit with dioxin-like PCBs alone.This highlights the role of commercial PCBs for global contamination with dioxin-like compounds.It was discovered that around metal industries,shredder plants,open burning sites of e-waste and dump sites,a high share of contamination was caused by dl-PCBs.This clearly shows severe PCB release from the end-of-life management of PCB-containing equipment in developing countries.Also highly contaminated eggs were found at many sites where plastic was incinerated.The highest contaminated egg sample ever measured came from an e-waste site in Ghana and had 856 pg TEQ/g fat plus 300 pg TEQ from brominated dioxins(PBDD/Fs).Other extreme PCDD/F contaminations of eggs were found at a chlor-alkali site(514 pg TEQ/g fat),Agent Orange contaminated areas in Vietnam(490,249 and 246 pg TEQ/g fat)and e-waste sites(568 and 520 pg TEQ/g fat).Where DR CALUX®bioassay revealed higher TEQ compared to measured PCDD/F-PCB-TEQ in IPEN studies,polybrominated PBDD/F were also measured and detected up to 300 pg TEQ/g fat at e-waste sites.One positive outcome from the IPEN studies is that all 10 pooled supermarket eggs in developing countries were below regulatory limit.Policy recommendations are made including:a systematic assessment of areas around PCDD/Fs and PCBs sources;measures for reduction of exposures of populations;urgent control of emission sources including PCB equipment,the open burning of plastic,and the use of plastic as fuel in boilers/incinerators in developing countries without air pollution control.Furthermore,soil limits need to be re-assessed and lowered for free-range poultry. | Jindrich Petrlik Lee Bell Joe DiGangi Serge Molly Allo'o Allo'o Gilbert Kuepouo Griffins Ochieng Ochola Valeriya Grechko Nikola Jelinek Jitka Strakova Martin Skalsky Yuyun Ismawati Drwiega Jonathan N.Hogarh Eric Akortia Sam Adu-Kumi Akarapon Teebthaisong Maria Carcamo Bjorn Beeler Peter Behnisch Claudia Baitinger Christine Herold Roland Weber | 2022 | Emerging Contaminants2022,8,1: | 2 |
| 6 | Large-scale permafrost degradation as a primary factor in Larix sibirica forest dieback in the Khentii massif,northern Mongolia显示文摘The objective of this study is to investigate the potential causes of widespread Larix sibirica Ledeb.mortality observed in the Khentii massif of northern Mongolia.The ratio of deadwood to living trees in affected stands in the Goricho region,the southernmost study site situated close to the Gobi Desert,was as high as 3.6:1.Moisture fluctuations monitored over 2 years using electrical impedance spectrometry revealed that the Goricho study site had higher soil moisture levels than the two less affected sites Barun Bayan and Dzun Bayan.High soil moisture was recorded in an area characterized by highly skeletal soils,ones with more than 35%by volume of rock fragments,and comparatively shallow soil horizons,from valley to mountains.The layer of permafrost influencing hydrogeological processes is much deeper in the Goricho region compared to the undisturbed study sites.Redundancy analysis confirmed a significant number of dead L.sibirica on sites with developed soils.Live forest stands,however damaged,grow in this region on well-drained scree slopes or on rocky bastions.The mass mortality observed for L.sibirica may be directly linked to accelerated permafrost thaw in the area bordered by the Tuul and the Terelj Rivers.Our assumption is that L.sibirica root system necrosis occurred as a result of long-term waterlogging of developed soils with high spatial heterogeneity,normally able to absorb high quantities of groundwater.The areas unaffected were scree fields and rocky bastions characterized by adequate drainage.All of our findings support the primary stages of large-scale permafrost thaw,i.e.,correlating increases in soil moisture with increasing permafrost active layer thickness. | David Juricka Jitka Novotna Jakub Houska Jana Parilkova Jan Hladky Vaclav Pecina Hana Cihlarova Marcela Burnog Jakub Elbl Zdena Rosicka Martin Brtnicky Jindrich Kynicky | 2020 | Journal of Forestry Research2020,31,1: | 2 |

| 11 | Optimization of Root Section for Ultra-long Steam Turbine Rotor Blade显示文摘This study presents the comparison of aerodynamic performances of two successive designs of the root profiles for the ultra-long rotor blade equipped with a straight fir-tree dovetail. Since aerodynamic and strength requirements laid upon the root section design are contradictory, it is necessary to aerodynamically optimize the design within the limits given by the foremost strength requirements. The most limiting criterion of the static strength is the size of the blade cross-section, which is determined by the number of blades in a rotor and also by the shape and size of a blade dovetail. The aerodynamic design requires mainly the zero incidence angle at the inlet of a profile and in the ideal case ensures that the load does not exceed a limit load condition. Moreover, the typical root profile cascades are transonic with supersonic exit Mach number, therefore, the shape of a suction side and a trailing edge has to respect transonic expansion of a working gas. In this paper, the two variants of root section profile cascades are compared and the aerodynamic qualities of both variants are verified using CFD simulation and two mutually independent experimental methods of measurements(optical and pneumatic). | Jindrich Hala Martin Luxa David Simurda marek Bobcik Ondrej Novak Bartolomej Rudas Jaroslav Synac | 2018 | Journal of Thermal Science2018,27,2: | 1 |
