An efficient protocol for the synthesis of highly functionalized 2-aminoindolizines and pyrido[3,2-a]indolizines has been achieved via the reaction of N-RC(O)CH2-2-chloropyridinium bromides with 2-amino-1,1,3-tricyanopropene ...

Loday and Ronco introduced the notion of a trioid and constructed the free trioid of rank 1. This paper is devoted to the study of congruences on trioids. We characterize the least dimonoid congruences and the least semigroup ...

The architecture of the information object security management system and the intelligent decision support subsystem regarding cyber security operational management is offered particularly in conditions of uncertainty, ...

A dialgebra is a vector space equipped with two binary operations ⊣ and ⊢ satisfying the following axioms: (D1) (x ⊣ y) ⊣ z = x ⊣ (y ⊣ z), (D2) (x ⊣ y) ⊣ z = x ⊣ (y ⊢ z), (D3) (x ⊢ y) ⊣ z = x ⊢ (y ⊣ z), (D4) (x ⊣ y) ⊢ z = ...

We introduce the notion of a rectangular triband, construct a free rectangular triband and describe its structure.

The paper proposed a model for estimating the quantitative indicator of current risks of threats and cyberattacks realization on information communication systems of transport (ICST), that differs from the existing models ...

Ekologiczne ciecze smarująco-chłodzące, zawierające w swoim składzie olej słonecznikowy, podczas obróbki skrawaniem stali wysokostopowych (stosowanych w generatorach elektrowni cieplnych i jądrowych) polepszają chropowatość ...
