The purpose of this study was to investigate whether a previously developed computer model, named Pore-Cor, could simulate the subtle changes in void space dimensions which occur during the artificial deposition of small amounts of illite and kaolinite within Fontainebleau sandstone. Clay precipitation was carried out by placing a sandstone plug in a gold capsule, with an aluminosilicate gel, a...

The main mode of failure of the acetabular component in total hip arthroplasty is aseptic loosening. Successive generations of cementation techniques have evolved to alleviate this problem. This paper evaluates one such method, Negative Pressure Intrusion Cementation. Two groups of machined bovine cancellous bone samples were created; experimental (n = 26) and control (n = 26). The experimental...

For years, the American Heart Association has recommended eating an average of two to three fishmeals each week to help reduce cholesterol, high blood pressure, and hardening of arteries. Research shows that consuming fish increases high quality protein with fewer calories, and it is rich in omega-3 fatty acids. Omega-3 fatty acid helps to reduce the risk of coronary artery disease, helps in th...

The study on the adsorption and micropore filling of water vapor in coal is significant for predicting coalbed methane content seams. primary purpose this to explain effects pore structure its surface chemistry monolayer adsorption, filling, diffusion coefficient. First, X-ray diffraction (XRD) mercury intrusion porosimetry (MIP) analyzed inorganic mineral components two kinds samples fissures ...

In this paper, the mechanisms of hydrate formation in presence porous activated carbon particles (PACP) loaded with cyclopentane (CP) and immersed an excess pure water are investigated using differential scanning calorimetry (DSC) combination gas porosimetry (GP) mercury intrusion (MIP). PACP different pore size distributions (PSDs) used CP hydrates formed at atmospheric pressure 1 °C. desorpti...

Many petrophysical properties (e.g. permeability, electrical resistivity etc.) of tight rocks are very stress sensitive. However, most mercury injection measurements are made using an instrument that does not apply a confining pressure to the samples. Here we further explore the implications of the use and analysis of data from mercury injection porosimetry or mercury capillary pressure measure...

Processes of ̄uid transport through underground reservoirs are closely related with microscopic properties of the pore structure. In the present work, a relatively simple method is developed for the determination of the topological and geometrical parameters of the pore space of sedimentary rocks, in terms of chamber-and-throat networks. Several parameters, such as the chamber-diameter distribu...
