Needle-punched geosynthetic clay liner (NPGCL) has been widely used in landfills. The internal strength of the GCL changes with temperature variation, which affects its application A large-scale temperature-controlled direct shear apparatus was developed to study characteristics affected by temperature. dependent on bentonite, fibers, and interaction between fibers bentonite. influence mainly r...

The compatibilization of raw bentonite (bent) with a polymer matrix polypropylene (PP) can improve the performance material in terms thermal and mechanical properties. In this study, two kinds untreated bentonite, bentonite-Maghnia (bent-m) bentonite-Mostaganem (bent-M), that differ proportion Al2O3 particle size distribution were coupled to typical maleic anhydride grafted PP-MA. Stearic Acid ...

the present study was carried out to investigate the effect of various refining processes’ conditions on conjugated dienes in soybean oil. conjugated dienes contents of soybean oil were found to undergo reduction in neutralization and bleaching steps while being increased in deodorization. it was observed that alkali refining (neutralization) through 12 and 14 °bé, bleaching with either acid ac...

Erosion is one of the important unlikely problems in oil refining industry that produces many damages and values to refining parts. In other part stop of refining operation for repairing is very expensive. Many erosions are happened in refining operations when equipments are placed to atmosphere, Powerful acids, eruption gases, hydrocarbon vampires and high temperature make very complex situati...

In the treatment of industrial polluted sites and construction landfill sites, anti-pollution barriers are usually used to prevent diffusion pollutants. this paper, adsorption characteristics Zn ions by rock-bentonite barrier were observed means static equilibrium dynamic tests. The experimental results showed that stone chips—bentonite was close nonlinear Freundlich Langmuir models. When conce...

This work produced glass foams from soda-lime bottles, bentonite, and alumina by the replica method. Compositions with different contents of bentonite (5, 10, 15, 20 wt%) were prepared heat-treated at 800 °C. In alumina-added compositions, 50 wt% was replaced alumina. The influences content (binder) addition evaluated through physical-mechanical properties. results showed that did not promote a...

The Gram-negative bacterium Stenotrophomonas bentonitica BII-R7T was isolated from bentonite formations. Like other species within the genus Stenotrophomonas, strain BII-R7T possesses high tolerance to numerous heavy metals, suggesting potential for bioremediation purposes. The draft genome sequence reported here comprises 4.37 Mb with a G+C content of 66.5% and 3,796 predicted protein-coding s...

To evaluate treatments purportedly beneficial for livestock grazing locoweeds (LW), growing rats were fed diets containing 10 or 20% whole-plant Oxytropis sericea (LW) with and without Silent Herder mineral mix (1.5% of diet) or bentonite clay (1.5% of diet). Pregnant female rats fed 10% LW were treated i.m. with Banamine (a prostaglandins suppressor) or saline. The LW contained swainsonine (43...

The effect of bentonite fining on the total proteins and the heat-unstable (80°C, 6 h; 4°C, 12 h) proteins in GewLirztraminer, White Riesling, Sauvignon blanc, and Sylvaner wines was investigated. Protein molecular weights (MW), isoelectric points (pl), and glycoproteins were determined by using lithium dodecyl sulfate polyacrylamide gel electrophoresis (LDS PAGE) and two-dimensional isoelectri...
