the purpose of this study was to look for carbon materials for composting with rabbit manure. rabbit manure was composted with rice straw and mushroom residues. during the composting process, different related parameters were evaluated. results showed that the rabbit manure could be normally co-composted with rice straw or with mushroom residues. the gi value showed that both composts could hel...

A pilot-scale modified Orbal oxidation ditch with internal recycle of the nitrified liquor was developed to significantly enhance total nitrogen (TN) removal through simultaneous nitrification/denitrification (SND) coupled with pre-denitrification under the aerated-anoxic condition. Long-term operational results showed that the highest TN removal efficiency was achieved at very low dissolved ox...

The efficient operation of existing plants in the process industry requires their analysis through simulation together with power and heat integration by retrofitting. Pinch Analysis (PA) is a classical procedure to achieve this goal. Yet, a further integration can be obtained reducing the entropy generated in the chemical processes. Ammonia, important as raw material in many process industries...

BACKGROUND About half of the orthodontists recycle and reuse orthodontic wires because of their costs. So when talking about reuse and sterilization of wires, their effects on mechanical properties of wires should be clarified. The purpose of this study was to assess the effects of sterilization and clinical use on mechanical properties of stainless steel wires. MATERIALS AND METHODS Thirty s...
