Philippe Calain discusses the health and environmental hazards of extractive industries like mining and explores the tensions that arise when medical humanitarian organizations are called to intervene in emergencies involving the extractive sector.

In this work, we obtain and compare the control properties of thermally coupled reactive distillation sequences and thermally coupled extractive distillation sequences with those of conventional reactive and extractive distillation configurations. All sequences have been designed using a multiobjective genetic algorithm with restrictions. The theoretical control properties of those schemes were...

The active parts of 11 medicinal plants were analyzed for physico-chemical evaluation, phytochemical determination and antioxidant activity. The physico-chemical evaluation revealed that highest water soluble extractive was from Origanum vulgare (38%), highest chloroform extractive was from Psoralea corylifolia (21%); highest ethanolic extractive was that of Acorus calamus (11%) and the highest...

The influence of operating conditions to the effectiveness of extractive distillation process was investigated by using the method of gas chromatography. The experiment took place on an industrial vacuum plant of purification ethanol from impurities formed during fermentation. It is obtained that the concentration of different micro impurities at the selection zones depends on the temperature a...

The objective of this study was to evaluate different pretreatment methods prior to oxygen delignification on extractives removal and O-delignification selectivity. Four different pretreatment methods were used including ultrasonic treatment, hot water soaking, soda addition-preheating, and applying a high-shear mechanical pretretament. Acacia mangium and mixed hardwood (MHW) kraft pulps were u...

In this paper we examine the application of an unsupervised extractive summarisation algorithm, TextRank, on a different task, the identification of argumentative components. Our main motivation is to examine whether there is any potential overlap between extractive summarisation and argument mining, and whether approaches used in summarisation (which typically model a document as a whole) can ...

The effectiveness of an extractive distillation process relies on the choice of the extractive solvent. The conventional methodology to select solvents is based on Group Contribution Methods. Ionic liquids have shown several advantages over conventional solvents used in extractive distillation and liquid-liquid extraction processes. However, there is no existing methodology to select ILs as sol...

Cnicus wallichi DC belonging to the family Asteraceae, was studied to fix the parameters for pharmacognostical standards in order to ensure the use of only genuine and uniform materials of such herbal remedies, work on standardization assumes vital significance. Pharmacognostical study has therefore, been carried out, covering detailed morphological and anatomical characters, features of the po...
