Background Vascular anomalies of the Aortic arch can cause respiratory symptoms in children due to tracheal compression. Treatment consists of division of the vascular rings, nevertheless data regarding mid- term results is scarce. The purpose of thi

The objective of this study was to examine whether aortic stiffness, as assessed by pulse wave analysis, could reliably discriminate between normal and hypertensive pregnancies. One hundred pregnant women were studied: five with severe pre-eclampsia,

Powders of Ni–C nanoparticles were synthesized using a pulsed arc between Ni electrodes submerged in pure ethanol. The arc was ignited by inter-electrode breakdown. The ethanol was arc treated for 5 min with 1 μs duration pulses, at a repetition r

Aramid fibres are still the fundamental variety of organic high-strength high-modulus fibres used in soft armor. In our opinion, fibres with high mechanical, primarily strength, indexes and with the corresponding level of supermolecular structure and
