The essence of the concept circular economy was determined. processes transition to a are analyzed, as result which three levels distinguished: efficient use materials; product life extention; smart production and products. connection between sustainable development implemented. main business models considered: Resources recovery, Sharing platforms, Product extension, service, Circular supplier...

we introduce a new concept of general $g$-$eta$-monotone operator generalizing the general $(h,eta)$-monotone operator cite{arvar2, arvar1}, general $h-$ monotone operator cite{xiahuang} in banach spaces, and also generalizing $g$-$eta$-monotone operator cite{zhang}, $(a, eta)$-monotone operator cite{verma2}, $a$-monotone operator cite{verma0}, $(h, eta)$-monotone operator cite{fanghuang}, $h$-...

ependymomas are glial tumors originate from ependymal cells lining the ventricles and the central canal of the spinal cord. two thirds of ependymomas arise in the infratentorial or intraventriclesandone-third aredetected in supratentorial area. however supratentorial “cortical” ependymomas are veryuncommon. ependymomas are usually infratentorial, intraventricular tumor, including 2–9% of all ce...

We describe an extention of the Standard Model (the νMSM) by three light singlet Majorana fermions – sterile neutrinos, which allows to address simultaneously the problem of neutrino oscillations and the problems of dark matter and baryon asymmetry of the Universe. We discuss the ways these new particles can be searched for in astrophysical, laboratory, and accelerator experiments.
