a chelating resin is prepared by condensation polymerization of aniline with formaldehyde andcharacterized by ft-ir, elemental analysis and studied for the preconcentration and determination of traceplatinum ion from environmental water sample using inductively coupled plasma-atomic emission spectroscopy(icp-aes). the optimum ph value for sorption of the metal ions was 5. the maximum adsorption...

due to the explosive growth of the world-wide web, automatictext summarization has become an essential tool for web users. in this paperwe present a novel approach for creating text summaries. using fuzzy logicand word-net, our model extracts the most relevant sentences from an originaldocument. the approach utilizes fuzzy measures and inference on theextracted textual information from the docu...

the effect of different extraction rates (64%, 82% and 90%) of wheat flour on the rheological properties of the wheat flour dough was investigated. a complete study of the rheological behavior of the wheat flour dough was performed by using three different instruments namely alveograph, extensograph, and farinograph. the correlation coefficient among the various parameters of applied methods wa...

this study presents the natural dye recovery from various biodegradable temple and household wastes. the raw material for colour extraction consisted residual flowers and garlands from various temples as well as onion and vegetables peels from vegetable markets, university hostels, and households, which were washed, dried, crushed, and sieved. the extracted natural colours were produced by mean...

ultrasound-assisted extraction was used to determine the optimum processing conditions and to achieve the maximum extraction yield and viscosity of the gum extracted from quince seed. using response surface methodology (rsm) to design the experiments and adopting the central composite rotatable design (ccrd), the effect of extraction temperature (25-55°c), time (3-10 minutes), and ph (6-8) were...

Biomedical information is growing rapidly in the recent years and retrieving useful data through information extraction system is getting more attention. In the current research, we focus on different aspects of relation extraction techniques in biomedical domain and briefly describe the state-of-the-art for relation extraction between a variety of biological elements.

plants are rich source of phenolic compounds (phenolic acids, flavonoids and tannins) that are most important natural antioxidants. in the present study two ultrasonic methods including probe and bath were used for the extraction of phenolic and flavonoid compounds from celtis australis. the effects of different extraction time including 30, 60 and 90 min (bath method) and 5, 10 and 20 min (pro...

Continuous counter-current extraction of rhenium from roasting dust leach liquor was carried out using a mixer-settler extractor. Tributylphosphate was used as the extractant diluted in kerosene. The effects of the flow rates and extraction stages number were investigated. The extraction efficiency was affected by the flow rates of the aqueous and organic phases, and its mechanism was qualitati...

In this paper we present an information service system that allows users to search for the key players of requested technology areas and for their collaboration networks. This system utilizes information extraction and wrapper technologies for detecting persons, organizations, publications and patents as well as relationships among them. Furthermore, it applies relation extraction to detect sta...
