The remnants of pesticides in livestock feeds have been increased by excessive using of these pesticides so as to meet extreme demands for more feeds. Finding a new strategy for reducing pesticides negative effects is absolutely necessary. Therefore, evaluation of the effects of sodium bentonite on blood parameters, feed digestibility and rumen fermentation parameters in sheep fed diets contami...

Soilless culture in greenhouse is being developed in Iran, as in many countries of the world. This study was conducted to evaluate the possibility of applying sawdust as well as the effect of adding bentonite and pumice on vegetative growth of bell pepper cv. Inspratian. The experiment was conducted as a completely randomized blocks design with 8 treatments and 4 replications, in greenhouse of ...

The study of drying and wetting cycles in soils is important due to their effects on plant nutrition and soil fertility as well as environmental issues. Therefore, a laboratory experiment was set up with a completely randomized design and factorial arrangement in three replications to identify the influence of wetting and drying cycles in combination with or without application of organic acids...

Gharenaz bentonite contains montmorillonite as the major mineral constituent and Ca as the major exchangeable cation. In the present study, the structural changes occurred in the course of acid activation of this bentonite was investigated by chemical analysis using  ICP-AES and phase analysis using XRD methods. Chemical analysis showed that most of the exchangeable cations i.e. K+, Na+ and Ca2...

Sealing with waterborne clays is a rapid and low cost method of controlling seepage through porous media whenever the clay source is within economical shipping distance of the sealing site. But more must be learned about this method of sealing before it can be fully utilized. Water impedance of waterborne bentonites, as measured by water loss in the filter press test, was correlated with their ...

−− Clarification of apple juice by flocculation and precipitation with bentonite and gelatin is explained on a more systematic basis, essentially through the determination of turbidity and zetapotential. Apple juice was also treated with Polyvinylpolypyrrolidone (PVPP) to remove total polyphenol. Gelatin-particle complex was evaluated as the increase in juice turbidity after the adding of tanni...

Researches on feeding with Biolekks premix and bentonite clay to pigs for fattening were conducted. It was established that the tested additives have beneficial effect on animals. However the greatest effect was obtained with combined feeding. So the live weight of pigs increased by 5.2% (at P≤0.999), surviving – by 4%, the level of profitability of pork production – by 18.6%, also revealed was...

The inhibitors derived from degradation of lignocellulose have adverse impacts on fermentation, which is considered to be a fundamental problem in bioethanol production. Fermentation of steam-exploded corn stover prehydrolyzate by Pichia stipitis showed that phenolic compounds had much higher inhibitory effects than weak acids and furan at high fermentation pH. Two types of organobentonite (cet...

The occurrence of deoxyribonucleic acid (DNA) antibodies in the sera of patients with systemic lupus erythematosus (SLE) has been established by several authors by different techniques. Their diagnostic value has been studied in more extensive series of patients by Jokinen and Makitalo (1960: passive haemagglutination and complement-fixation), Kayhoe, Nasou, and Bozicevich (1960: bentonite floc...
