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...

Since 195D many studies have been devoted to physical and chemical trans-Formations in plasmas. In this paper we do not propose to make an exhaustive overview but to underline the main development points oF plasma chemistry. First after a brie-F historical review, we present the plasma chemical reactors and describe the difFerent types oF plasma generators. We discuss then oF the two main param...

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 ...

Barriers and bridges to implement policies about sustainable development and sustainability commonly depend on the past development of social-ecological systems. Production of metals required integration of use of ore, streams for energy, and wood for bioenergy and construction, as well as of multiple societal actors. Focusing on the Swedish Bergslagen region as a case study we (1) describe the...

Extractive distillation is an alternative for ethanol dehydration processes that has been shown to be more effective than azeotropic distillation and, in close proximity, to be very competitive against the process that uses adsorption with molecular sieves. Glycols have been shown to be the most effective solvents in extractive distillation, mainly ethylene glycol and glycerol. In this work, an...

Text summarization is the process of automatically creating a compressed version of a given document preserving its information content. There are two types of summarization: extractive and abstractive. Extractive summarization methods simplify the problem of summarization into the problem of selecting a representative subset of the sentences in the original documents. Abstractive summarization...

Increases in spiny lobster size and abundance have been observed within some marine protected areas (MPAs). To date, the potential economic benefits of these changes have been assumed to derive from the effects of emigration of adult lobster to adjacent fishing grounds and/or increased larval export to downstream nurseries that sustain fisheries. According to economic theory, these effects may ...
