ABSTRACT It is obvious in recent publications that pores and pores size distribution play an important role in flow generation, yet the study of dynamic behavior of the effects of pores and pores size distribution on flow characteristics is somewhat rare.... see more

Les effets Dufour et Soret sur la convection naturelle thermosolutale dans une couche poreuse horizontale sont étudiés numériquement en utilisant la méthode des différences finies et analytiquement en utilisant l'approximation de l’écoulement parallèle. D... see more

Earthworms affect macro-pore structure of soils. However, some studies suggest that earthworm burrow walls and casts themselves differ greatly in structure from surrounding soils, potentially creating habitat for microbivorours nematodes which accelerate ... see more

We have examined the influence of the most widely used silicon-organic surface water repellent GKZH-11K on the physical-mechanical properties and the phase structure formation of cement is the fact that the introduction of the surface water repellent GKZH... see more

The paper deals with the monitoring of brick body in the process of volumetric freezing and thawing. The samples were fired at temperatures of 900, 1000 and 1060°C. Attention is focused on monitoring of the irreversible expansion, water absorption and por... see more

In this study, the effects of polystyrene (PS) latex addition on the particle morphology and the pore content of calcium oxide (CaO) were investigated. The CaO particles were prepared using an ultrasonic nebulizer-assisted spray-pyrolysis method with vari... see more

Portland cement pastes of various porosities were prepared using water/cement ratios of 0.30, 0.35, 0.40, 0.45, 0.50 and 0.55; and were hydrated for various time intervals ranging from 0.021 to 28 days.  Pore structure and VL–t plots (plots of volume... see more

Electrochemical anodizing titanium metal in the fluorine-containing electrolyte to produce nanotubes of titanium dioxide. The surface morphology of the films was investigated by scanning electron microscopy. It was found that with increasing anodizing vol... see more
