The present work aims at the chemical characterization of several non-woody fibers from herbaceous plants used for manufacturing high quality paper pulps, with especial emphasis in the composition of lignin and lipophilic compounds. Among the fibers studied are bast fibers from flax, hemp, kenaf and jute and leaf fibers from abaca and sisal. Flax and hemp showed the lowest lignin content (< 5%)...

Improving the mechanical and physical properties of bio-composite materials involves incorporation plant fibers such as Jute, Hemp, Kenaf, Ramie, Sisal, Linen, etc. The existence Diss grass (Ampelodesmos mauritanicus) in abundance east Algeria especially Khenchela region taking into account their resistance low density, which justifies choice use composite materials. Tensile hardness tests for ...

Influence of sulfur dioxide (SO2) and lactic acid (LA) on grain sorghum steeping efficiency in terms of wetmilling characteristics was investigated using response surface analysis. Tested ranges of concentrations in steeping water were 0.050 to 0.278% and 0 to 0.282% for SO2 and LA, respectively. Measured wet-milling variables were steeping solids yield, starch yield, protein yield, fiber/germ ...

this experiment was conducted in safi abad agricultural research center of dezful in order to study the effect of seed deterioration and plant density on germination, seedling establishment, yield and yield components of hull-less barley with in 2011- 2012. treatments included three levels of seed deterioration: (control, 72 and 96 hours) and five plant densities (100, 150, 200, 250 and 300 pla...
