Slag of aluminum is a residue which results during the melting process of primary and secondary aluminum production. Salt slag of aluminum is hazardous solid waste according to the European Catalogue for Hazardous Wastes. Hence, recovery of aluminum not only saves the environment, but also has advantages of financial and economic returns. In this research, aluminum was recovered and purified from the industrial wastes generated as waste from both of State Company for Electrical and Electronic Industries (Baghdad/AlWaziriya) and General Company for Mechanical Industries (Babylon/-Al-Escandria).

Résumé :
Petroleum-derived products, such as lubricant oils, are non-renewable resources that, after use, must be collected and processed properly to avoid negative environmental impacts. A circular economy of used oils requires the re-refining and reuse of the same. Similar to most countries in Latin America, the management of used oils in Ecuador is still incipient and few cities collect and treat this material properly.

IntroductionThe common origin of the adjective “corporeal” and the noun “corpse” in the Latin root corpus points to the value of mortuary practices for investigating how the human body is objectified. In post-mortem rituals, the body—formerly the manipulator of objects—becomes itself the object that is manipulated. Thus, these funerary rituals provide a type of double reflexivity, where the object and subject of manipulation can be used to reciprocally illuminate one another. To this extent, any consideration of corporeality can only benefit from a discussion of how the body is objectified thr

Résumé :
Introduction In December 2010, Nespresso, the world’s leading brand of premium-portioned coffee, opened a flagship “boutique” in Sydney’s Pitt Street Mall. This was Nespresso’s fifth boutique opening of 2010, after Brussels, Miami, Soho, and Munich. The Sydney debut coincided with the mall’s upmarket redevelopment, which explains Nespresso’s arrival in the city: strategic geographic expansion is key to the brand’s growth.
