Descurainia sophia is widely distributed in China and is one of the most troublesome annual weeds. It has diverse medicinal usage. D. sophia has abundant oil, making it an important oil plant in China. The main goal of this study was to obtain the maximum yield of the oil by an optimal selection of supercritical fluid extraction parameters. According to the central composite design and response...

Revalorization of the winery industry residue, grape seed is studied for the production of an oil and defatted meal with nutraceutical properties. Conventional grape seed oil extraction process is carried out by pressing at high temperature affecting the product quality. Oil extraction by cold pressing improves product quality, but it gives a low oil yield. Oil extracted is increased at the pre...

A simple, nondestructive PCR-based screening method has been developed for identifying putative transgenic soft white winter wheat (Triticum aestivum L.) carrying the coat protein gene of wheat streak mosaic virus. Removal of the endosperm end of individual seed provided sufficient material for DNA extraction and PCR. DNA from seed is more free of the secondary, metabolites found in leaf tissue...

distribution of retinal blood vessels (rbvs) in retinal images has an important role in the prevention, diagnosis, monitoring and treatment of diseases, such as diabetes, high blood pressure, or heart disease. therefore, detection of the exact location of rbvs is very important for ophthalmologists. one of the frequently used techniques for extraction of these vessels is region growing-based se...

Part-whole relation, ormeronymy plays an important role in many domains. Among approaches to addressing the part-whole relation extraction task, the Espresso bootstrapping algorithm has proved to be effective by significantly improving recall while keeping high precision. In this paper, we first investigate the effect of using fine-grained subtypes and careful seed selection step on the perform...

The oxygen radical absorbance capacity (ORAC) of bilberry (Vaccinium myrtillus) powder and dried nettle (Urtica dioica) seed powder was studied. In addition, the affect of the following parameters in the ORAC analysis were investigated: 1) extraction solvent (acetone/water, ethanol and acidic methanol), 2) extract dilution, and 3) addition of ethylenediaminetetraacetic acid disodium salt hydrat...

We propose a framework for object extraction with accurate boundaries. A multilayer perceptron is used to identify seed points through examples, and regions are extracted and localized using a locally coupled network with weight adaptation. A functional system has been developed and applied to hydrographic region extraction from Digital Orthophoto Quarter–Quadrangle images.

We present the Vancouver Event and Relation System for Extraction (VERSE)1 as a competing system for three subtasks of the BioNLP Shared Task 2016. VERSE performs full event extraction including entity, relation and modification extraction using a feature-based approach. It achieved the highest F1-score in the Bacteria Biotope (BB3) event subtask and the third highest F1-score in the Seed Devel...

Iso-surface extraction is one of the most important approaches for volume rendering, and iso-contouring is one of the most effective methods for iso-surface extraction. Unlike most other methods having their search domain to be the whole dataset, iso-contouring does its search only on a relatively small subset of the original data-set. This subset, called a seed-set, has the property that every...

Plant polyphenolic compounds have been recognised for their ability to prevent oxidation of susceptible substances by virtue of their electron donating property due to presence of large number of phenolic hydroxyl groups. The seed of Areca catechu contains higher proportions of polyphenolic compounds mainly tannins. Our objective involves quantification of tannins, determination of total phenol...
