The aim of this clinical case - to suggest the pathogenesis and etiology of relapsing oligoarthritis in the patient.Цель данного клинического наблюдения - проведение дифференциальной диагностики и предположение этиопатогенеза протекающего рецидивирующего олигоартрита у ребенка

Bulk and surface morphologies of ABC miktoarm star terpolymers comprised of PDMS, PI and PMMA arms

DIM miktoarm star copolymers, composed of polydimethylsiloxane [D], poly(1,4-isoprene) [I], and poly(methyl methacrylate) [M], were synthesized using a newly developed linking methodology with 4-allyl-1,1-diphenylethylene as a linking agent. The equilibrium bulk morphologies of the DIM stars were found to range from [6.6.6] tiling patterns to alternating lamellar and alternating cylindrical morphologies, as determined experimentally by small-angle X-ray scattering and transmission electron microscopy and confirmed by dissipative particle dynamics and self-consistent field theory based arguments. The thin film morphologies, which differ from those found in the bulk, were identified by scanning electron microscopy, coupled with oxygen plasma etching. Square arrays of the PDMS nanodots and empty core cylinders were formed on silica after oxygen plasma removal of the poly(1,4-isoprene) and poly(methyl methacrylate) which generated nanostructured substrates decorated with these features readily observable

Experience in the use of surgical access to the distal part of the radius in comminuted intra-articular fractures

The purpose of the study. Experimental evaluation of bioresorbable Mg-Ca-Zn alloy implants in vitro and in bone tissue in vivo, in order to determine the optimal rate of biodegradation, biocompatibility and reparative response of bone tissue.Цель исследования. Экспериментальная оценка биорезорбируемых имплантатов из сплава Mg-Ca-Zn in vitro и в костной ткани in vivo для определения оптимальной скорости биодеградации, биосовместимости и репаративного ответа костной ткани

Algorithm for measuring distortion in a signal with quadrature phase shift keying (QPSK)

The article describes the types of distortion of the QPSK signal and the algorithms for measuring the parameters of distortions in the conditions of their simultaneous presence in the signal.</jats:p
