A greener method based on cloud point extraction was developed for removing phenol species including 2,4-dichlorophenol (2,4-DCP), 2,4,6-trichlorophenol (2,4,6-TCP) and 4-nitrophenol (4-NP) in water samples by using the UV-Vis spectrophotometric method. The non-ionic surfactant DC193C was chosen as an extraction solvent due to its low water content in a surfactant rich phase and it is well-know...

Quantitative changes in groundwater and crises resulting from uncontrolled water extraction have turned water resources management into one of the supply-demand dilemmas in arid regions. The present study evaluated the quantitative situation of water resources in the Ardestan Plain adjoining the Ardestan desert by using the MODFLOW mathematical model. Simulation of groundwater flow in the stead...

A stakeholder is an individual, group, organization, or community that has an interest or stake in a consensus-building process. The goal of stakeholder identification is identifying stakeholder mentions in natural language text. We present novel work in using a bootstrapping approach for the identification of stakeholders in public comment corpora. We refine the definition of a stakeholder by ...

The present study describes a method based on headspace-solid-phase dynamic extraction (HS-SPDE) followed by GC/MS for the qualitative and quantitative analysis of benzene, toluene, ethylbenzene, o-, m- and p-xylene (BTEX), and n-aldehydes (C(6)-C(10)) in water. To enhance the extraction capability of the HS-SPDE a new cooling device was tested that controls the temperature of the SPDE needle d...

Ginseng leaf/stem extract produced by subcritical water extraction at high temperature (190°C) possess higher cytotoxic activity against human cancer cell lines than ethanol extract. Subcritical water extraction can be a great candidate for extraction of functional substance from ginseng leaves/stems.

Extraction and separation of proteins is important for their interesting applications as continuous enzymatic reaction and/or product separation systems. In this work, a new highly efficient homogeneous capture and heterogeneous liquid–liquid separation strategy is presented for the extraction of proteins from aqueous solution by PEG (poly(ethylene glycol))-functionalized ionic liquids, which h...

The present article includes the Ultrasound-Assisted Extraction (UAE) of Citrus unsiu Marc. leaves rich in polyphenols. The best possible combinations of solvent, pH of the media, solvent/solid ratio, extraction time, extraction temperature and particle size were obtained for the maximum extraction of Total Phenolic Compounds (TPC) and Total Flavonoid Compounds (TFC) by us...

The purpose of this study was to extract visual design elements related Kansei value by applying principal component analysis (PCA) color images. A questionnaire survey on impression evaluations for images various sports shoes conducted Japanese and Americans. shoe used in the were converted CIE Lab system, PCA based each axis (i.e., luminance axis, red-green yellow-blue axis), components could...
