The new way of purification of silicon hexacoordinated tris-products [Si(L)3]I4 from [Si(L)2I2]I2 where L is diimide ligand is presented. The effectivity of the suggested method is proven by H1 NMR spectroscopy data. ...

The five known lactones matricarin, austricin, canin, and achillin guaianolides and argolide germacranolide and the two flavonoids eupatilin and its 7-O-methyl ester were isolated for the first time from the aerial part ...

Four sesquiterpene lactones with the germacrane structure were isolated from the aerial part ofStizolophus balsamita. X-ray structure analyses showed that two of them were previously known balsamin derivatives. A third was ...

Any set of uniqueness for regular method of summation for trigonometric series is also a set of uniqueness. J. Marcinkiewicz and A. Zygmund constructed regular method of summation for that there not exist sets of uniqueness. ...

Data are presented from BOR-60 irradiations showing that significant radiation-induced swelling causes severe embrittlement in austenitic stainless steels, reducing the service life of structural components and introducing ...

The need to ensure LTE network coverage in sparsely populated and rural areas of Europe (ITU Region 1) has led to a massive use of 800 MHz band (band 20) with its good characteristics of radio wave propagation in LTE net- ...

We prove sharp stability estimates for the variation of the eigenvalues of non-negative self-adjoint elliptic operators of arbitrary even order upon varia-tion of the open sets on which they are defined. These estimates ...

Изготовлен прибор и внедрена методика исследования , позволяющие определять механические свойства высокорадиоактивных материалов, облученных до высоких повреждающих доз. Исследовано влияние толщины образца d на результаты ...

This article aims to provide a historical ground for future research on geopolitical and economic transformations in Asia. It is devoted to the current situation around two Central Asian megaprojects: The U.S.'s "New Silk ...
