Rice hull is the by-product from rice processing that rich of dietary fiber content. The objectives of our study were to evaluate the effects of dietary fiber level from grounded rice hull on growth performance, nutrient digestibility, intestinal morphology and bacterial cell count in hindgut of weaning … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 1 · 28 Mar 2020 · 7,304 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfiltration of Nanoparticles into Porous Binder Jet Printed PartsAmelia Elliott, Sarah AlSalihi, Abbey L. Merriman, Mufeed M. BastiThe densification of parts that are produced by binder jetting Additive Manufacturing (AM; a.k.a. “3D Printing”) is an essential step in making them mechanically useful. Increasing the packing factor of the powder bed by incorporating nanoparticles into the binder has potential to alleviate the amount of shrinkage needed for full densification of binder jet parts. In this study we present … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 11 Mar 2016 · 13,395 accessesView PDFCite
Research ArticleOpen accessIn the abstractPorosity Analysis in Porous Brass Using Dual ApproachesRyan Yeargin, Rob Ramey, Cindy WatersThe goal of this research is to produce porous samples for various applications such as heat exchangers, filters and radiation shields. The level of porosity is an important objective yet the level of confidence in two main methods (hand calculations and microscopic analysis) is not high. This work will compare porosity values obtained from traditional hand calculations against analysis from … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 25 Feb 2016 · 8,525 accessesView PDFCite
Research ArticleOpen accessIn the abstractFORCED CONVECTION HEAT TRANSFER, FLOW CONFIGURATION AND THERMAL PERFORMANCE IN A SQUARE CHANNEL WITH MODIFIED V-SHAPED BAFFLESAmnart Boonloi, Withada JedsadaratanachaiThe influences of modified V-shaped baffle in a square channel for heat transfer and thermal performance enhancement are presented numerically in three Dimensional (3D). The V-shaped baffles are modified in order to comfortable to installation in the square channel. The plates are used for clamping on both the upper and lower V-shaped baffles resulting the modified V-shaped baffle like orifice … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 7 Apr 2014 · 6,690 accessesView PDFCite
