This study evaluated the efficiency of electrocoagulation in removing chemical oxygen demand (COD), turbidity, and apparent color from incineration effluent generated a gas cleaning system (GCS). Modeling optimization variables electric current (I), hydraulic retention time (HRT), electrode distance (ED) were also performed batch reactor using iron electrodes. A 23 rotatable central composite d...

Pose estimation is one of the vital issues in mobile robot navigation. Odometry data can be fused with absolute position measurements to provide better and more reliable pose estimation. This paper deals with the determination of better relative localization of a two wheeled differential drive robot by means of odometry by considering the influence of parameters namely weight, velocity, wheel p...

Spent coffee grounds (SCGs) generated in processing for beverages and other products are a very significant organic residue that needs to be properly treated. Waste valorization via oil extraction has the potential obtain compounds can used producing biodiesel or high-value products, such as polymers. This work focuses on ultrasound-assisted of SCG using n-hexane solvent. Three key process para...

This study aimed to investigate the effect of an innovative ecofriendly process—instant controlled pressure drop technology, also known as “détente instantanée contrôlée” or DIC—coupled with Tripolium extraction (DIC-Tripolium), on hesperidin recovery, and antioxidant antidiabetic activities orange byproduct extracts. A DIC pretreatment was applied partially dried byproducts (~16% wet basis). c...

This research aims to formulate and to optimize a nanoemulsion-based formulation containing fullerene, an antioxidant, stabilized by a low amount of mixed surfactants using high shear and the ultrasonic emulsification method for transdermal delivery. Process parameters optimization of fullerene nanoemulsions was done by employing response surface methodology, which involved statistical multivar...

The well-known probiotic GRAS Saccharomyces boulardii (CNCM I-745) was used for the first time to produce glutathione (GSH). culture conditions affecting GSH biosynthesis were screened using a Plackett–Burman design (PBD). Analyzing regression coefficients 12 tested variables, yeast extract, glucose, peptone, cysteine, temperature and agitation rate had positive significant effect on production...

Burnishing is a method of finishing and hardening machined parts by plastic deformation of the surface. Experimental work based on central composite second order rotatable design has been carried out on a lathe machine to establish the effects of ball burnishing parameters on the surface roughness of brass material. Analysis of the results by the analysis of variance technique and the F-test sh...
