Long-term performance estimations were performed on a nonstandard domestic solar water heating system by f-Chart, interactive F-Chart software, and φ̄,f-Chart methods. Results of estimations were compared to gain insight of their applicability. Results from F-Chart software and f-Chart agree well and are greater than those from the φ̄,f-Chart method. Energy dumping should be given thorough reconsideration for the refinement of f-Chart and F-Chart software. Copyright © 2014 by ASME. Source

Pool boiling of multi-walled carbon nanotube (MWCNT) nanofluid was conducted to investigate fouling of a copper surface with a diameter of 12 mm. At low heat flux the fouling curve takes the shape of saw tooth with an asymptotic value. When boiling stretches, dispersant, Gum Arabic fails, MWCNT particles deposit on the heating wall completely. Progressively increasing the heat flux, depositing accelerates, superheat and fouling resistance increase drastically. © Springer-Verlag 2011. Source

The potential biological functions of Pleurotus eryngii have long been described in Chinese traditional medicine. However, little is known about the bioactive components of P. eryngii and their functions in liver injury and high-fat induced animal models. The present study thoroughly investigated the comprehensive functions of water-soluble polysaccharidic extract of P. eryngii (PEPE) using in vivo mouse models and in vitro biochemistry tests. PEPE could significantly increase the activities of antioxidant enzymes and effectively remove the free radicals in a liver-injury mouse model. Furthermore, in a high-fat-load mouse model, PEPE not only remarkably decreased the lipid levels of total cholesterol, total triglyceride, and low-density lipoprotein cholesterol, but also resulted in an increase in high-density lipoprotein cholesterol. Histopathological observations indicated that PEPE could effectively prevent excessive lipid formation in liver tissue. Our data suggest that PEPE can be used as a valuable functional food additive for hypolipidemic and hepatoprotective treatments. © 2011 Elsevier Ltd. All rights reserved. Source

The method of ultrasoft pseudopotential within the generalized gradient approximation has been employed to study the elastic constants and electronic structure of (Al,Si)3Sc precipitate with L12 structure in Al-base alloys. Based on the calculated results, the elastic properties of (Al,Si)3Sc precipitate were investigated. The Young's and shear modulus of the polycrystals for (Al,Si)3Sc precipitate were calculated using Voigt-Reuss-Hill averaging scheme. The calculated results of elastic properties showed that the (Al,Si)3Sc precipitate has a strengthening effect in the Al matrix, owing to the larger shear modulus differences between (Al,Si)3Sc and Al matrix. The calculated results also showed that (Al,Si)3Sc precipitate is brittle in nature. © (2011) Trans Tech Publications, Switzerland. Source

A simple, rapid and environment friendly extraction method, dispersive liquid-liquid microextraction (DLLME), was developed in combination with high performance liquid chromatography-diode array detector (HPLC-DAD) for the extraction and determination of levonorgestrel (LNG) in water samples. The main parameters affecting the microextraction efficiency were optimized for the first time using uniform design (UD). The statistical parameters of the derived model were R2 = 0.9898 and F = 85.608. The optimum conditions were 50 L of trichloromethane (the extraction solvent), 50 L of methanol (the disperser solvent), 0% (w/v) of sodium chloride and 140 s of the extraction time. Under the optimum conditions, a much lower volume of organic solvent was used, and the proposed method showed high enrichment factor (428), good linearity behavior (r = 0.9995) within a range of 1-300 g L-1, low limit of detection (0.3 g L-1), satisfactory repeatability (the relative standard deviation (RSD) of 5 g L-1 LNG was 5.9%, n = 6), and high recoveries (from 94.3 to 101.4%). The method was successfully applied for the determination of LNG in tap water, lake water and river water samples. © 2011 The Royal Society of Chemistry. Source
