Most patients with CI need to undergo radiation diagnostics during their lifetime, including magnetic resonance imaging (MRI) and computed tomography (CT). Modern cochlear implants are currently compatible with MRI up to 1.5 T. However, clinics condu

Isolated anomalies of the middle ear are one of the most difficult areas of practical otorhinolaryngology. Its relevance is due to the rare occurrence, high technical complexity of performing surgical treatment, and the high frequency of unsatisfacto

Diaminodiphenyl sulfone is used as a curing agent to obtain an epoxy-resin-based binder with improved thermal stability. The kinetics of curing of this composition is studied by rheokinetic and calorimetric methods. It is shown that complete conversi

In this paper, we introduce homological structure theory of semirings and CP-semirings---semirings all of whose cyclic semimodules are projective. We completely describe semisimple, Gelfand, subtractive, and anti-bounded, CP-semirings. We give comple

We study the semirings whose simple semimodules are all projective. In particular, we establish that for every semiring S this condition implies the injectivity of all simple S-semimodules and show that, in contrast to the case of rings, the projecti

During long-term operation heat-resistant ferrite and martensitic steel welds have type IV cracking in a so-called ‘soft layer’, which contains part of fine grain region and inter-critical region of heat-aff ected zone (HAZ). The rupture of dissi
