Since the early days, natural products have played a significant role in drug discovery and development. However, the extraction process of these compounds often includes many complex steps, consumes a lot of energy and a large volume of solvents, which can have a significant impact on the environment as well as human health. Therefore, it is necessary to find better ways to improve the yield of extraction, while minimizing risks that may affect the environment and humans.

Furthermore, experiments on the task of RE proved that data representation is one of the most influential factors to the model’s performance but still has many limitations. We propose a compositional embedding that combines several dominant linguistic as well as architectural features and dependency tree normalization techniques for generating rich representations for both words and dependency relations in the SDP

Nacre organic matrix has been conventionally classified as both
water-soluble and
water-insoluble,basedonits solubility in aqueous solutions after decalcificationwith acid or EDTA. Some characteristics (aspartic acid-rich, silk-fibroin-like content) were specifically attributed to either one or the other. The comparative study on the technique of extraction (extraction with water alone vs. demineralization with EDTA) presented here, seems to reveal that this gen-erally accepted classification may need to be reconsidered....

Increasing evidence suggests that melatonin can exert some effect at nuclear level. Previous experiments using binding techniques clearly showed the existence of specificmelatonin binding sites in cell nucleus of rat liver. To further identify these sites, nuclear extracts fromrathepatocyteswere treated withdifferent percentages of ammoniumsulfate andpurified by affinity chromatography. Subsequent ligandblot analysis shows the presence of two polypeptides of

We describe Joshua (Li et al., 2009a)1 , an open source toolkit for statistical machine translation. Joshua implements all of the algorithms required for translation via synchronous context free grammars (SCFGs): chart-parsing, n-gram language model integration, beam- and cubepruning, and k-best extraction. The toolkit also implements suffix-array grammar extraction and minimum error rate training. It uses parallel and distributed computing techniques for scalability.

The major aims of this project centred around building capacity in protected cropping systems, trialling these systems with tomatoes and cucumbers in Vietnam and introducing farmers and other supply chain partners to these systems. As such, the emphasis was never intended to be on improving supply chains, merely examining current vegetable supply chains and determining the major problems. This milestone was added to the project after the original design and in-fact was extracted from another CARD project and added into this project.
