Chlorine disinfection is a vital treatment process to inactivate pathogens, but it also generates numerous halogenated disinfection byproducts (DBPs) via reactions with halides and natural organic matter (NOM)[1]. Epidemiological studies have shown that consumption of chlorinated drinking water with halogenated DBPs is related to increased spontaneous abortions, stillbirth,

Chlorine disinfection of saline wastewater effluents rich in bromide and iodide forms relatively toxic brominated and iodinated disinfection byproducts(DBPs). Ultrasonication is a relatively new water treatment technology, and it is less sensitive to suspended solids in wastewaters. In this study, we examined the effects of ultrasonication(in terms of reactor type and combination mode with chlorination) on the DBP formation and toxicity in chlorinated primary and secondary saline wastewater effluents. Compared with the chlorinated wastewater effluent samples without ultrasonication, ultrasonic horn pretreatment of the wastewater effluent samples reduced the total organic halogen(TOX) levels in chlorination by ~30%, but ultrasonic bath pretreatment of the wastewater samples did not significantly change the TOX levels in chlorination, which might be attributed to the higher energy utilization and decomposition extent of organic DBP precursors in the ultrasonic horn reactor. Moreover, the TOX levels in the chlorinated samples with ultrasonic horn pretreatment(USH–chlorination), simultaneous treatment(chlorination + USH) and subsequent treatment(chlorination–USH) were also significantly reduced, with the maximum TOX reductions occurring in the samples with ultrasonic horn pretreatment. A toxicity index was calculated by weighting and summing the levels of total organic chlorine, total organic bromine and total organic iodine in each treated sample. The calculated toxicity index values of the chlorinated wastewater effluent samples followed a descending rank order of “chlorination” > “chlorination + USH” > “chlorination–USH” > “USH–chlorination”, with the lowest toxicity occurring in the samples with ultrasonic horn pretreatment. Then, a developmental toxicity bioassay was conducted for each treated sample. The measured toxicity index values of the chlorinated wastewater samples followed the same descending rank order.

Generating canopy-reflectance datasets using radiative transfer models under various leaf and optical property combinations is important for remote sensing retrieval of vegetation *** radiative transfer models have been frequently ***,three-dimensional(3D)models usually require detailed 3D information that is difficult to obtain and long model execution time,limiting their use in remote sensing *** study aims to address these limitations for practical use of 3D models,proposing a semi-empirical speed-up method for canopy-reflectance simulation based on a LargE-Scale remote sensing data and image Simulation model(LESS),called *** speed-up method is coupled with 3D LESS to describe the dependency of canopy reflectance on the wavelength,leaf,soil,and branch optical properties for a scene with fixed 3D structures and observation/illumination configurations,allowing fast generating accurate reflectance images under various wavelength-dependent optical *** precomputed dataset stores simulated multispectral coefficient images under few predefined soil,branch,and leaf optical properties for each RAdiation transfer Model Intercomparison-V scene,which can then be used alone to compute reflectance images on the fly without the participation of ***-LESS has been validated with full 3D radiative-transfer-simulated images,showing very high accuracy(root mean square error<0.0003).The generation of images using Semi-LESS is much more efficient than full LESS simulations with an acceleration of more than 320 *** study is a step further to promote 3D radiative transfer models in practical remote sensing applications such as vegetation parameter inversions.

Measurements of carbon dioxide(CO_(2)),methane(CH_(4)),and carbon monoxide(CO)are of great importance in the Qinghai-Tibetan region,as it is the highest and largest plateau in the world affecting global weather and climate *** this study,for the first time,we present CO_(2),CH_(4),and CO column measurements carried out by a Bruker EM27/SUN Fourier-transform infrared spectrometer(FTIR)at Golmud(36.42°E,94.91°N,2808 m)in August *** mean and standard deviation of the column-average dry-air mixing ratio of CO_(2),CH_(4),and CO(XCO_(2),XCH_(4),and XCO)are 409.3±0.4 ppm,1905.5±19.4 ppb,and 103.1±7.7 ppb,*** differences between the FTIR co-located TROPOMI/S5P satellite measurements at Golmud are 0.68±0.64%(13.1±12.2 ppb)for XCH_(4) and 9.81±3.48%(–10.7±3.8 ppb)for XCO,which are within their retrieval *** correlations for both XCH_(4) and XCO are observed between the FTIR and S5P satellite *** the FLEXPART model and satellite measurements,we find that enhanced CH_(4) and CO columns in Golmud are affected by anthropogenic emissions transported from North *** study provides an insight into the variations of the CO_(2),CH_(4),and CO columns in the Qinghai-Tibetan Plateau.

前人研究发现食物摆盘的美感水平会影响个体的食物选择,但未有研究进一步探讨相同美感、不同审美特征对健康饮食决策的影响机制。本研究招募被试34名,采用基于价值的食物决策范式,使用2 (审美特征:古典美,表现美)×2 (食物热量:高,低)被试内设计,通过分离计算模型参数与脑电指标来检验不同审美特征差异化的审美价值,以及审美价值对热量影响的调节效应及其认知神经基础。结果显示:(1)古典美(vs.表现美)审美价值更高,食物选择率和漂移率(v)更高、N400振幅更低;(2)审美价值调节热量价值,但热量价值的突显性高于审美,热量信息的神经处理时间更早(240~320ms);(3)审美价值的调节效应发生在决策证据积累过程中,影响漂移率(v)以及中央顶叶正波(CPP)。本研究在理论层面揭示了健康饮食决策中审美价值的调节效应及认知神经基础,同时在实践应用方面为助推健康饮食选择提供了食物摆盘的审美设计指导。
