This paper presents a practical approach for rational choice of silica nanopowders as modifiers to control and improve the performance of protective coating systems operating in harsh environmental conditions.The approach is based on the multiparameter analysis of nanoparticle reactivity of similar silica synthesized by using chemical and physical

The report presents an approach to the filtration of alternatives when choosing a counterparty for horizontal cooperation based on multiple criteria.Filtration procedures precede the optimization procedures for multi-criteria decisions.The SHIRTS URBAN SHORT SLV filtration is based on the theory of binary relations and preserves only alternatives-m

One of the results of several decades of mass migration from Europe to America in the 19th and 20th centuries was the creation of ethnic "communities" in the host countries, composed by the immigrants themselves Trucker Hat and their descendants.Even though early theories that proposed the idea of American society as a melting-pot in which all Old-

Abstract Background The Coronavirus disease 2019 (COVID-19) caused by the new Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has become a pandemic, affecting the therapeutic management for Multiple Sclerosis (MS).Any decision regarding the discontinuation of high-potency agents for moderate and highly active MS should be carefully Lum

Abstract We propose various new 3d N $$ mathcal{N} $$ = 2 dualities exploiting their recently discovered connection JOINT-PRO CONCENTRATE to the duality relations for 2d free field CFT correlators.Most of the dualities involve, as the main building block, a quiver theory with monopole superpotential which enjoys various interesting properties such
