The lifetime of a blast furnace (BF), and, consequently, the price of steel, strongly depends on the degradation of micropore carbon refractory materials used as lining materials in the BF hearth. One of the major degradation mechanisms in the BF hea

A non-equilibrium diffusion–reaction model is proposed to describe chloride transport and binding in cementitious materials. A numerical solution for this non-linear transport with reaction problem is obtained using the finite element method. The e

Permeability of experimental and standard micropore carbon materials, before and after the heat treatment at 1550 °C, was investigated using gas permeability measurements (GP) and mercury intrusion porosimetry (MIP). Permeability of both materials i

Permeability of experimental micropore carbon material was investigated based on the solution of steady-state pore-scale flow in geometry representing real material pores in 2D and 3D. Geometries for calculations were created based on the X-ray micro

Pore morphology of experimental micropore carbon materials was explored using non-destructive methods. The influence of the heat treatment on porosity of two micropore carbon materials was investigated using helium porosimetry (HP) and X-ray micro-co

Background: The CHADS2 and CHA2DS2-VASc scores were shown to predict mortality in patients with atrial fibrillation. However, pathophysiology and treatment outcomes of atrial fibrillation and typical atrial flutter (AFL) differ. Consequently, the pro
