−− The aim of this work is to simulate and analyze an extractive distillation process (extractive distillation and recovery columns) for the separation of Tetrahydrofuran (THF)-Water azeotropic mixture using Aspen Plus® and Aspen Split simulators. Calculation of vapor liquid equilibrium of Tetrahydrofuran–Water–Entrainer system was done using the NRTL model, which binary interaction parameters ...

Extractive text summarization is the process of selecting relevant sentences from a collection of documents, perhaps only a single document, and arranging such sentences in a purposeful way to form a summary of this collection. The question arises just how good extractive summarization can ever be. Without generating language to express the gist of a text – its abstract – can we expect to make ...

Extractive butanol fermentation with non-ionic surfactant, a recently explored area, has shown promising results with several advantages but is relatively less investigated. This work reports the extractive fermentation with selected non-ionic surfactants (L62 and L62D) to enhance butanol production using a high-butanol producing strain (Clostridium beijerinckii MCMB 581). Biocompatibility stud...

Most extractive summarization methods focus on the main body of the document from which sentences need to be extracted. However, the gist of the document may lie in side information, such as the title and image captions which are often available for newswire articles. We propose to explore side information in the context of single-document extractive summarization. We develop a framework for si...

BACKGROUND Monascus pigments are promising sources for food and medicine due to their natural food-coloring functions and pharmaceutical values. The innovative technology of extractive fermentation is used to promote pigment productivity, but reports of pigment trans-membrane secretion mechanism are rare. In this study, tracking of pigment accumulation and secretion in extractive fermentation o...

In some previous work, we have presented a software tool for experimenting with well known methods for text summarization. The methods offered are belonging to the extractive summarization direction. These methods do not understand the meaning in order to condense the text but simply extract a subset of the original sentences which are the most (promising as being) relevant for expressing short...

Extractive speech summarization approaches select relevant segments of spoken documents and concatenate them to generate a summary. The extraction unit chosen, whether a sentence, syntactic constituent, or other segment, has a significant impact on the overall quality and fluency of the summary. Even though sentences tend to be the choice of most the extractive speech summarizers, in this paper...

To study the chemical constituents of Piper wallichii (Miq.) Hand.-Mazz., and to explore the effects of extractive on proliferation and telomerase activity of human tongue squamous cell carcinoma Tca83 cells and its anti-cancer mechanisms. Sephadex LH-20 and several other column chromatography techniques were employed for separation of chemical constituents from Piper wallichii (Miq.) Hand.Mazz...

The absorption spectra of visual purple solutions extracted by various means were measured with a sensitive photoelectric spectrophotometer and compared with the classical visual purple absorption spectrum. Hardening the retinas in alum before extraction yielded visual purple solutions of much higher light transmission in the blue and violet, probably because of the removal of light-dispersing ...

This paper is a meditation on the possibilities of walking performance as an embodied territorial acknowledgement. It discusses problems verbal or treaty acknowledgements, and asks whether acknowledgements might overcome those problems. settlers land can begin to enter into kinship relationship with it, they are locked scopophilic extractive ways experiencing therefore incapable seeing themselv...
