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...

Drill mud is a fluid which is used in oil extraction industries in order to cool and lubricate the drill bit. Due to containing numerous toxic components, it is considered as a hazardous waste which must be treated before discharging to the environment. Current separation techniques for drill cutting treatment can be categorized into three main categories of physical (dewatering), physiochemica...

it has been reported that latex and extracts of different species of ficus are cytotoxic to some human cancerous cell lines. in this study, cytotoxicity of fruit and leaf extracts as well as the latex of ficus carica l. on hela cell line were evaluated. ethanolic extracts of leaves and fruits were prepared through percolation and ethyl acetate and dichloromethane extracts were prepared by reflu...

introdouction: impacted mandibular third molar surgery may affect periodontal status of the adjacent second molar. the purpose of this study was to evaluate the changes in periodontal health parameters distal to the adjacent second molar following surgical extraction of an impacted mandibular third molar. materials and methods: we selected 50 subjects with a mean age of 22.8 (ranging from 18 to...

mandibular incisor extraction in carefully selected cases as an alternative option to four bicuspid extraction or non extraction treatment has been advocated. the purpose of this study was to determine the degree of improvement in occlusion in patients with bolton discrepancy treated by one lower incisor extraction using peer assessment rating index (par indexes).pre and post treatment dental c...
