In situ extractive fermentation was used to produce 4-vinyl derivatives, from hydroxycinnamic acids extracted from corn cobs, by recombinant Escherichia coli containing the phenolic acid descarboxylase (PAD) gene. This microorganism mainly produced 4-vinylphenol (4VP) from p-coumaric acid (p-CA). In a first study, we observed that concentrations of 4VP >1 g/L had a negative impact on descarboxy...

Summarization is a way to represent same information in concise way with equal sense. This can be categorized in two type Abstractive and Extractive type. Our work is focused around Extractive summarization. A generic approach to extractive summarization is to consider sentence as an entity, score each sentence based on some indicative features to ascertain the quality of sentence for inclusion...

The possible application of imidazolium ionic liquids as energy-efficient green material for extractive deep desulfurization of liquid fuel has been investigated. 1-Butyl-3-methylimidazolium chloride [BMIM]Cl was synthesized by nucleophilic substitution reaction of n-methylimidazolium and 1-chlorobutane. Molecular structures of the ILs were confirmed by FTIR, (1)H-NMR, and (13)C-NMR. The therma...

In this paper, we propose a novel framework for extractive summarization. Our framework allows the summarizer to adapt and improve itself. Experimental results show that our summarizer achieves higher evaluation scores by adapting to the given evaluation metrics.

The total flavonoid content (TFC), total polyphenols content (TPC), and in vitro antioxidant activity (AA) of six Bidens pilosa L., Asteraceae, populations harvested from different localities were evaluated in this work. The plants were separated in roots, stems, and leaves/flowers, and the influence of extraction methods was investigated. A reversed-phase high-performance liquid chromatography...

Task complexity (Fagot & Vauclair 1991), bimanual complementary role differentiation (Uomini 2009), and the obligate use of a particular hemisphere (Rogers, 2009) have been proposed to explain why hand preferences in non-human primates are often influenced by tasks. We examined how tasks (reaching, carrying, extractive foraging, and object manipulation) and gender influenced hand preference in ...

Volatile fatty acids (VFAs) can be readily produced from many anaerobic microbes and subsequently utilized as precursors to renewable biofuels and biochemicals. Megasphaera elsdenii represents a promising host for production of VFAs, butyric acid (BA) and hexanoic acid (HA). However, due to the toxicity of these acids, product removal via an extractive fermentation system is required to achieve...

Context: Nigella sativa Linn. (Ranunculaceae) is native to southwest Asia. This tree species has been of interest to researchers because it has a long history of folklore usage in various systems of medicines. Objective: Pharmacognostic Standardization, Physico and Phytochemical Evaluation of the seeds of N. sativa were carried out to determine its macro-and microscopical characters and also so...

UNLABELLED AIM.: The aim of this study is to evaluate the capability of Hyaloss™ matrix (Fab - Fidia Advanced Biopolymers - Pd - Italy), a biomaterial based on hyaluronic acid, used as organic scaffold in bone repair in post-extractive defects. MATERIALS AND METHODS 20 post-extractive sockets were selected, with similar size defects in the same patient and in the same hemiarch. Hyaluronic aci...

In an attempt to mitigate the environmental impacts caused by large farmers, extractive reserves (RESEXs) were founded with objectives of conserving biological diversity and meeting traditional communities’ vital needs. This study aimed evaluate whether human needs satisfaction conservation achieved based on institutional investments in a RESEX Brazilian Amazon. The was developed through associ...
