In this study, carbon nanotubes (CNTs) were grown directly in the pores of micro porous pyrex membranes and consequently ceramic membranes with very fine pores and high porosity were achieved. Our experiment was done in two stages. Initially cobalt powder with different percent was homogeneously mixed with pyrex powder. In order to produce row membranes, each of these mixtures were compacted in...

PURPOSE Cortical porosity is a key characteristic governing the structural properties and mechanical behaviour of bone, and its quantification is therefore critical for understanding and monitoring the development of various bone pathologies such as osteoporosis. Axial transmission quantitative acoustics has shown to be a promising technique for assessing bone health in a fast, non-invasive, an...

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...

This study verifies a novel approach to determine the thermal conductivity developed by first two authors (Tomanek and Stutts) [1] as applied additively manufactured selective laser melted stainless steel 304L specimens having range of 1.4 seven percent porosity. The melting technique is highly dependent on process parameters used, unlike traditionally materials, can cause thermal, electrical, ...
