With over 12 000 registered mixture formulations in China, environmental risk assessment of co-formulated pesticide mixtures to aquatic ecosystems is increasing interest scientists, assessors, and managers. This study proposed a pragmatic approach based on widely accepted scientific concepts strategies.The has three tiers, preliminary Tier 0 stage, 1 refinement stage as 2, which are demonstrated with one case study. Because the large number available unique practicable criteria identify...
Fourier transform infrared (FT-IR) imaging coupled with principal component analysis (PCA) is used to characterize the photooxidation of polypropylene (PP) and identify photooxidative products at different oxidation times. PP slices were exposed ultraviolet (UV) irradiation for times up 60 hours spatially resolved spectra acquired a transmission FT-IR system in order view steric inhomogeneity process PP. The evolution oxidized time shown through application PCA. Carboxylic acid major product...
Abstract The spatial variability of precipitation is often considered to be a major source uncertainty for hydrological models. widely used Soil and Water Assessment Tool (SWAT) insufficient calculate sub-basin's mean areal (MAP) since it only uses data from the rainfall station nearest centroid each sub-basin. Therefore, Inverse Distance Weighting (IDW), Thiessen Polygons (TP) Ordinary Kriging (OK) were applied as alternative interpolation methods in this study sub-basin MAP. MAP results...
In this paper, the characters of two control valves used for ammonia injection in SCR system are discussed. The linear/quadratic character between pressure drop/outlet flow rate and valve opening/dynamic inlet investigated using computational fluid dynamic (CFD) response surface analysis (RSA) methods. results show that linear brake is significantly better than butterfly valve, which means more suitable adjustment valve.
A rapid and sensitive high performance liquid chromatography - tandem mass spectrometry (HPLC-MS/MS) method for determination of gibberellin(GA3) residue in vegetables fruits was developed. The gibberellin samples were extracted with methanol solution, adjusted the pH value 3-4, then ethyl acetate. After evaporation, organic phase purified solid extraction using C18 column. detected HPLC-MS/MS quantified external standard method. Linear range between 0.01~10.0 μg/mL, detection limit 0.01...
Abstract Diamide insecticides are widely used in rice paddies and pose a potential threat to aquatic organisms. However, the risk research related their application major rice-producing areas is very limited, especially mesocosm simulate impact on ecosystems of long-term exposure, as well exposure analysis based local models scenarios. To assess risks from novel diamide insecticide (tetrachlorantraniliprole) nontarget organisms field over an outdoor study was performed, environmental...
The aim of this study was to gain insight into the knowledge of, attitude toward, and practical experience with listeriosis among medical staff. In two hospitals in Fangshan, Beijing, 410 staff members were randomly selected using a random sampling method. Each member invited participate standardized questionnaire interview. total, 397 valid questionnaires collected. With regard members' general listeriosis, they answered 65.96% items correctly. scores obstetricians gynecologists higher than...
In this paper, an online method was invested to evaluate the WFGD performance based on gas-liquid mass transfer analysis. According real-time analysis of SO<inf>2</inf> gas-phase coefficient Kg, i each spray layer limestone-gypsum system, evaluation system can be realized, and core reference basis for subsequent fault diagnosis operation provided.
To explore the applied talents and cultivation patterns of independent colleges according to its own characteristics development orientation,which survive as a high professional degree homogeneity in cracks colleges.Through case study University Electronic Science Technology China,Zhongshan Institute,the specific ideas,path measures pattern reform college are explored practiced from three aspects guiding ideology “two-aspect combination,two-way competition,integration development,diverse...
