This study was centered on improving the mechanical properties of AISI 8620 steel using carburization technique. The failure in service conditions many components such as cams, gears, and shafts necessitated research it demands that they possess both high wear-resistant surfaces tough shock-resistant cores. Standard test samples prepared from material were subjected to a pack process rice husk ...

This paper investigates the influence of adding vegetal fibers on thermal and acoustic performance based natural hydraulic lime. Mortar samples with 10% weight were fabricated water to obtain easily workable mortars good consistency; their was compared mortar without fibers. The different types (rice husk, spelt bran, Khorasan (turanicum) wheat chaff) size (as-found ground form). Thermal measur...

The use of rice husk (the waste in the production seeded (Oryza sativa) as a sorption material for removal pollutants various classes – inorganic (Cr, Ni, Co, Pb, Hg, As, Cd, Cu, Zn) and organic substances (synthetic natural dyes, phenols, antibiotics, polycyclic aromatic compounds, humic acids, pesticides, chitosan) from aqueous media is generalized. literature data on structure rice, volume i...

The biofiltration technique is of great importance for the removal heavy metals. In present work, a laboratory-scale biofilter was modeled using rice husk as filter material. Wolborska model used to know dimensions necessary function. Langmuir and Freundlich isotherms were performed quantify adsorption process, showing that are ones highest correlation coefficient best represent process Cd (II)...
