BACKGROUND The authors of this manuscript aimed to show the importance of porosity and condensation in health according to traditional Persian medicine (TPM) with consideration of new evidence in conventional medicine. METHODS Cardinal traditional medical and pharmacological texts were searched for the traditional terms of takhalkhol (porosity) and takassof (condensity) focused on preventive ...

In the paper the effects of nucleation and growth of voids in the plastic porous media are investigated. Three different forms of the model are considered: the augmented Gurson model (total porosity model) with variable nucleation and growth material function, the same model with constant growth material function and the separated porosity model. The identification of the material functions par...

The porosity of a material can be determined using a diversity of methods; however, the results from these methods have so far not been compared and analyzed for calcium phosphate cements (CPCs). The aim of this study was to compare a fast and easy method for porosity measurements with some commonly used porosity methods for CPCs. The investigated method is based on the assumption that when a w...

This study aims to evaluate soil moisture and bulk density effects on penetration resistance dynamics of Dark Red Latosol, located in the Microregion of Goiânia, Goias. Area under rotating pasture were sampled 1) in lines and 2) between lines; 3) pasture renewal area; 4) area under Central Pivot; 5) area under no-tillage and 6) forest. Penetrometry tests were done for three different soil moist...

Crown porosity influences radiation interception, air movement through the fruit orchard, spray penetration, and harvesting operation in fruit crops. The aim of the present study was to develop an accurate and reliable methodology based on transmitted radiation measurements to assess the porosity of traditional olive trees under different pruning treatments. Transmitted radiation was employed a...

The main objective of this work is quantitative evaluation of porosity in carbon fiber reinforced polymers (CFRP) with the help of X-ray computed tomography (XCT). For this purpose two types of sample were compared. Industrial porosity sample was obtained from an aeronautical industry. Artificially induced porosity samples were created by drilling holes with diameter 0.2 mm and 0.3 mm in non-po...

Calcareous stones such as Lecce stones have a high porosity which results in a readily uptake of rainwater. Due to the atmospheric pollutants dissolved in the water these stones, used in a lot of historical buildings, are constantly under attack which leads to a decay of the stone. Different kind of organic hydrophobic products such as Paraloid B72 and fluorinated rubber are often applied as pr...

The aim of the research that is presented in this paper was to evaluate the physical and mechanical properties of heat-insulating mortars with expanded cork aggregates and different binders. In this work, the measurements of surface roughness and adhesion strength, supported by determination of basic mechanical and physical parameters, such as density, bulk density, open porosity, total porosit...

improvement of soil properties through sustainable agriculture requires suitable management of plant residues. this study was conducted to investigate the effect of different types and managements of plant residue on soil physical properties in a field experiment as factorial based on rcbd with three replicates. the first factor was residue type including barley straw and alfalfa residue, and t...

harvesting of timber using ground based machinery is still a common practice around the world. track and road building, and movement of machinery during harvesting operations cause soil disturbance. therefore the aim of this study was to investigate the change in soil properties after logging operation on skid trails (2 years and 7 years after logging) and compare disturbed soil properties with...
