Determining an Efficient Solvent Extraction Parameters for Re-Refining of Waste Lubricating Oils

A metodologia empregada se baseia nos estudos de fatores pedológicos condicionantes de propriedades dos solos importantes para o projeto e construção de obras de engenharia

ABSTRACT: The present study aimed at investigating the chemical composition of essential oil extracted from Brazilian propolis and the susceptibility of

This study aimed to extract the oil from macauba pulp using a low-pressure solvent extraction, as well as characterisation of the extracts and defatted meal obtained using

Here, we consider a general regenerative process that includes Smith’s model and show that it is important to consider finite time quantities instead of asymptotic ones and

The objective of this study was to evaluate the effects of the extraction parameters (ethanol graduation, previous shaking time in an ultrasound bath and drug/solvent ratio) on

Na comunidade da Tapera, residem cinqüenta famílias (com as doze residentes na beira do rio e no Pereira); no Pau Grande, noventa e seis e trinta famílias e no Barreiro. Além

The adopted hypothesis was that the use of a well- founded Ontology Reference Model of the Recommendation ITU-T G.800 is able to give precise semantics to the transport

A educação em administração passa por um momento de questionamento e crítica quanto ao papel dos educadores e educandos, sinalizando para a necessidade de uma mudança tanto
