Passive seismic investigation of intraplate earthquakes epicentral zones in the north of Russia as one of the ways to understand their source mechanics

引用

Journal of Earth Science 2024年

Studying the inner structure of intraplate earthquakes originating in aseismic areas， which are poorly covered by seismic networks or as historical earthquakes is usually the only way to get knowledge about their source mechanisms that is partially important to deeper understand intraplate geodynamics. The epicentral zones of earthquakes are situated in hard-to-reach areas， so， using active seismic methods for such purposes is unreasonable or even impossible because of high cost and logistical difficulties. We are presenting a way to join using different passive seismic methods， which allows us to get sufficient information about geological environment structure for such task solutions. As an example， we investigated the inner structure of platform earthquake epicentral zone originated up north of Russia. We used four passive seismic methods: microseismic sounding method， passive seismic interferometry， HVSR method， and microseismic activity method. We show that passive seismic data， recoded in the same installation and processed by these different methods， can provide sufficient information about structure of studied environment， needed to explain source mechanism. In sum， the hypocenter zone is presented by intersection of vertical faults and a lateral fractured zone in the middle crust. Results were confirmed by comparison with results by active seismic methods.

通过室内模型试验，以普通尿素（U）、腐植酸包膜尿素（U-HA）和脲酶抑制剂n-（正丁基）硫磷三酰胺处理尿素（U-UI）为研究对象，研究了3种尿素肥料对土壤氮素转化过程的影响。更正研究了尿素肥料对土壤化学（水浸提n-nH4和n-nO3含量）和微生物特性（n2O实际和潜在排放速率、基础呼吸和底物诱导的呼吸、微生物生物量碳、乙烯排放速率）的影响，旨在验证：（i）腐植酸包膜尿素是否具有减少土壤氮素损失的能力；（ii）与合成脲酶抑制剂相比，它是如何影响土壤生物活性的。结果表明，U-HA在减少土壤氮素损失方面具有与U相当的优势，使土壤n-nH4含量增加了35%，硝酸盐含量减少了9%，n2O排放减少了50%。U-HA使土壤基础呼吸提高了10%，土壤微生物群落比活性提高了7%，提供了最高的代谢熵qCO2。与U-UI相比，U-HA主要表现为介于U-UI和U之间的效果。考虑到腐植酸原料成本低，U-HA可以被认为是减少土壤氮素损失的有前景的工具。

Influence of non-covalent interactions on properties of lanthanide systems with aromatic ligands

引用

Journal of Rare Earths 2008年第2期26卷 146-152页

作者： Lada Puntus konstantin Lyssenko Laboratory of Molecular nanoelectronics Institute of Radioengineering & Electronics Russian Academy of Sciences 11-7 MokhovayaMoscow 125009 Russia A. n. nesmeyanov Institute of Organoelement Compounds Russian Academy of Sciences GSP-1 28 Vavilov StreetMoscow 119991 Russia

Two series of lanthanide compounds, namely, chlorides containing different numbers of both 1,10-phenanthroline （Phen） molecules and chloride anions in the first coordination sphere, and Schiff Bases （SBs） derived from Pyridoxal （PL） and amino acids, were characterized by single crystal X-ray diffraction and luminescence techniques. The combined use of these techniques for the analysis of long-distance europium non-covalent interactions was performed for the first time. As a result, the correlation between supramolecular organization and the features of the Eum electronic transitions was found for the compounds of the first series. Strong non-covalent interactions between pyridoxal tings of SBs （the second series of compotmd） led to the formation of 1：2 species and four-dentate coordination function of these SBs in aqueous solution.

Restoration of function after cortical lesion: does it require an internal template?

neural Regeneration Research 2014年第23期9卷 2029-2031页

作者： Holger Schulze konstantin Tziridis Experimental Otolaryngology Friedrich-Alexander University Erlangen-Nürnberg

The brain controls virtually all body functions, both internally and in interaction with the external environment. As the basic body anatomy of all vertebrates has a bilateral symmetry, structures and functions of vertebrate brains are also organized according to this fundamental anatomical principle to meet all sensory, motor, and internal requirements of body control. Consequently, particular parts or functions of the body are controlled by particular brain structures.
