An improved particle swarm optimization (IPSO) was proposed and the intelligent algorithms such as IPSO, genetic algorithm (GA), simulated annealing (SA) were introduced to determine parameters of Van Genuchten (VG) model for soil water retention curve (SWRC) four typical agricultural textures (clay, clay loam, silt loam sand loam) in China.For comparison, SWRC term VG also fitted by a computer program RETC pedotransfer function Rosetta, respectively.For textures, value determination...
Abstract High frequency electrotome quality analyzer is widely used by medical institutions, equipment manufacturers, and testing institutions. There are several important technical indicators, such as high-frequency power, leakage current, output resistance, to evaluate the metrological performance of analyzers, but currently, there no corresponding verification regulations or calibration specifications. This article presents a method for high analyzers selecting specific test device,...
The water-soluble polysaccharides from Kaempferia galanga L. (KGPs) were extracted and purified, their structural characteristics antitumor activity further investigated. UV spectrum, high-performance gel permeation chromatography (HPGPC), Fourier-transform infrared spectroscopy (FTIR), ion (IC) employed to evaluate the characteristics, H22 tumor-bearing mice model was established demonstrate activity. Physicochemical analysis spectrum results showed that proportions of total sugar, protein,...
Pinocembrin is a natural flavonoid compound which capable of antioxidant, antibacterial, anti-inflammatory, and antineoplastic activities. The present study aimed to enhance the solubility antioxidant activities pinocembrin by complex formation with lecithin. physicochemical characteristics pinocembrin–lecithin were analyzed ultraviolet (UV), fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), differential calorimetry (DSC), assay, evaluated via radical...
Notably, clear spatial differences occur in the distribution of air pollution among cities Beijing-Tianjin-Hebei (BTH) Region. Clarifying concentration PM
The traditional ship collision risk index model based on the distance at closest point of approach (DCPA) and time to (TCPA) is insufficient for estimating planning avoidance operations. This paper constructs an elliptical, dynamic domain that changes with speed maneuverability parameters overcome subjective human factors. Based constructed model, concept proximity factor introduced improve DCPA TCPA, a calculation function considers safety navigation constructed. numerical improved confirms...
The effects of limiting factors such as rainfall intensity, duration, grass type and vegetation coverage on the stormwater runoff urban green space was investigated in Tianjin. prediction equation established by quantitative theory with lab experimental data soil columns. It validated three field experiments relative errors between predicted measured are 1.41, 1.52 7.35%, respectively. results implied that could be used to forecast space. range variance analysis indicated sequence order is...
Liuwei Dihuang (LWDH), a famous traditional Chinese medicine, is widely used in the clinical treatment of aging-related diseases China. However, its pharmacological mechanisms are not clear. In present study, we evaluated lifespan extension effect LWDH <i>C. elegans</i> and mice revealed underlying mechanisms. The results showed that significantly extended dose-dependent manner. also conferred protection to nematodes against oxidative stress reduced their fat storage. Genetics analysis...
Garlic is a vegetable known to be good antioxidant food resource around the world. Several studies on activity of garlic, mainly conducted using one or two methods, have been reported. However, comparison garlic before and after cooking rarely In this study, we compared aqueous methanol extracts processed boiling mimic process. By testing activities in different chemical systems <i>in vitro</i>, namely, ABTS [2, 2'-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid)] DPPH (2,...
