Text mining used on texts and publications in the biomedical molecular biology fields is referred to as "biomedical text mining." It a relatively new area of study at intersection computational linguistics, bioinformatics, natural language processing. Superior usefulness goal sequential pattern identify statistically significant patterns among data instances when values are presented sequential...

He Q., Ren Y., Mohamed I., Ali M., Hassan W., Zeng F. (2013): Assessment of trace and heavy metal distribution by four sequential extraction procedures in a contaminated soil. Soil & Water Res., 8: 71–76. Four sequential extraction procedures (Sposito, Tessier, Silveira and Bureau Communautaire de Reference (BCR)) were used to evaluate the distribution of some metals (Fe, Cu, Cd and Zn) in a co...

A novel stir bar sorptive extraction (SBSE) procedure termed sequential SBSE was developed. Compared to conventional SBSE, sequential SBSE provides more uniform enrichment over the entire polarity/volatility range for organic pollutants at ultra-trace levels in water. Sequential SBSE consists of a SBSE performed sequentially on a 5-mL sample fi rst without modifi er using one stir bar, then on ...

The effect of sequential extraction of trace metals on sulfur (S) speciation in anoxic sludge samples from two lab-scale biogas reactors augmented with Fe was investigated. Analyses of sulfur K-edge X-ray absorption near edge structure (S XANES) spectroscopy and acid volatile sulfide (AVS) were conducted on the residues from each step of the sequential extraction. The S speciation in sludge sam...

This article carried out the extraction of sesame oil by using three extraction techniques: supercritical fluid extraction (SFE), Soxhlet and sequential extraction. The SFE was performed using supercritical carbon dioxide (SC-CO2) as solvent and ethanol as cosolvent. Tests were performed at 20 MPa, 35°C and a flow rate of 2.5 g CO2/min with a total extraction time of 210 minutes. The Soxhlet ex...

Wheat bran is a major by-product of cereal production that still has limited use for advanced nutritional and material applications. A sequential process using subcritical water, membrane filtration and selective enzymatic treatments has been designed for the combined fractionation of functional high molar mass hemicelluloses (over 10 g mol) and oligosaccharides from wheat bran. This process no...
