The main purpose of this text is to offer what could be a kind road map within the possible archaeometric protocols address old problem posed by ceramics with negative decoration and relationships that would have occurred between Western Mexico South America. A perspective also offered on from technological point view, according ethnoarchaeological analyses, important since despite great tempor...

Diesel is composed of various toxic compounds that can have a negative influence on the environment including plants, microorganisms, and even groundwater being used for cultivation and human consumption. Diesel oil biodegradation kinetics was investigated using bubble-column reactor and microbial consortium isolated from a hydrocarbons spill site and were assessed<em...

We employ dispersion-corrected density functional theory to study adsorption of CH4 molecule on a singly and doubly decorated (8,0) single wall carbon nanotube (CNT80) with palladium atom oxygen molecule. The obtained optimized energies indicate that double decoration molecules significantly enhance methane the CNT80, while give rise weak physical bonding for Moreover, we observe decreases band...

Nowadays recycling wastewater is a task in progress. New ways of contamination have appeared together with the technology development. Our article deals with the case of wastewater contaminated with dispersed colorants that are used during the decoration of paper boxes for packaging various products. The wastewater treatment is based on the electro-flotation process. The system is fully automat...
