Chemical composition of the dufour gland secretion in queens of Melipona bicolor (Hymenoptera, Meliponini)
(2004-09-01)
We describe differences in the chemical composition of the Dufour gland secretion of virgin and physogastric queens of Melipona bicolor through gas chromatography and mass spectrometry. The Dufour gland secretion of virgin ...
The use of pineapple leaf fibers (PALFs) as reinforcements in composites
(2014-09-05)
Pineapple leaf fibers (PALFs) can be utilized as fabrics for textile materials and in the manufacture of yarns and handicrafts in many countries. The excellent mechanical properties and environmentally sustainable ...
Effect of chemical composition and microstructure on the mechanical behavior of fish scales from Megalops Atlanticus
(ELSEVIER SCIENCE BV, 2016-03-01)
This paper presents an experimental study of the composition, microstructure and mechanical behavior of scales from the Megalops Atlanticus (Atlantic tarpon). The microstructure and composition were evaluated by Scanning ...
Modeling of syngas composition obtained from fluidized bed gasifiers using Kuhn–Tucker multipliers
(2018-06-01)
This work aims to develop a modified chemical equilibrium model to accurately determine the syngas (synthesis gas) composition obtained from fluidized bed gasifiers. In order to do so, an optimization method was applied ...
