This study collected past sampling data on total concentrations of 12 heavy metals (Cd, Pb, Cr, Hg, Zn, Cu, Ni, Al, Fe, Mn, As, and Co) in surface water bodies, i.e., 168 rivers 71 lakes, from 1972 to 2017. The intent was investigate the levels sources metal pollution across five decades continents. Mean global river lake water, number with greater than published threshold limits as per standards both World Health Organization (WHO) United States Environmental Protection Agency (USEPA) were...
An improved optical security system based on two phase-only computer-generated masks is proposed. The transparencies are placed together in a 4f correlator so that known output image received. In addition to simple verification, our capable of identifying the type input mask according corresponding it generates. phase designed with an iterative optimization algorithm constraints and domains. A simulation presented resultant images formed by elements. Various combinations compared show...
We applied a submegahertz nonlinear optical filter afforded by cryogenically cooled spectral-hole burning crystal to ultrasound-modulated tomography. Our experimental results show that this technique, having the largest etendue among all available tomography techniques and being immune speckle decorrelation, offers potential for imaging in vivo forming high resolution tomograms real time. It opens an opportunity development of clinically applicable modality.
Abstract The biomass of filamentous fungi is an important cost-effective for heavy metal biosorption. However, use free fungal cells can cause difficulties in the separation from effluent. In this study, we immobilized living conidia metal-resistant Penicillium janthinillum strain GXCR by polyvinyl alcohol (PVA)-sodium alginate (SA) beads to remove metals aqueous solution containing a low concentration (70 mg/L) Cu, Pb, and Cd. PVA-SA-conidia showed perfect characters appropriate mechanical...
Eutrophication and exotic species invasion are key drivers of the global loss biodiversity ecosystem functions in lakes. We selected two plants (Alternanthera philoxeroides Myriophyllum aquaticum) native (Myriophyllum spicatum Vallisneria spinulosa) to elucidate effect eutrophication on plant invasiveness. found that (1) elevated nutrient favored inhibited growth plants. Species combinations densities had limited effects resistance exotics. (2) A. featured tightest connectivity among traits,...
Abstract Floodplain wetlands have a significant capacity for carbon sequestration but are vulnerable to land use changes. Poplars extensively planted in due the increasing demand wood products and bioenergy. Although large biomass of poplar may increase stock wetlands, high transpiration rate reduce soil moisture, thereby improving aeration wetland soils facilitating oxidation organic materials. Therefore, impact poplars on stocks is undetermined remains unexplored. Here, we investigated...
We propose a method of synthesizing computer-generated holograms real-life three-dimensional (3-D) objects. An ordinary digital camera illuminated by incoherent white light records several projections the 3-D object from different points view. The recorded data are numerically processed to yield two-dimensional complex function, which is then encoded as hologram. When this hologram plane wave, real image reconstructed.
Addressing the global challenge of bacterial resistance demands innovative approaches, among which multitargeting is a widely used strategy. Current strategies multitargeting, typically achieved through drug combinations or single agents inherently aiming at multiple targets, face challenges such as stringent pharmacokinetic and pharmacodynamic requirements cytotoxicity concerns. In this report, we propose bacterial-specific disruption approach vastly expanded strategy that effectively...
This study evaluated the effects of young poplar plantations on understory plant diversity in Dongting Lake wetlands, China. Poplar resulted a higher species number and Shannon's diversity. Species compositions were different between areas with reed populations: lower ratio hygrophytes but mesophytes, heliophytes neutrophilous or shade plants compared to areas. supported ligneous entire area, there was no difference monitored plots. Unlike reedy areas, had light availability soil water...
Based on the wetland areas recorded in First National Inventory of Wetland Resources (FNIWR; 1999–2001) and Second (SNIWR; 2009–2011), as well regional environmental parameters including meteorological conditions land-use structure, driving forces changes China’s area from FNIWR to SNIWR were investigated. The total wetlands larger than 1 km2 decreased 384.8 × 103 350.8 SNIWR. Natural areas, marshes, rivers, lakes, coastal wetlands, by 33.8 over study period, accounting for 99.4% decrease...
Although antibiotics have played a certain positive role in the prevention and treatment of poultry diseases, as well promotion growth, some farmers use an incorrect way breeding process, resulting antibiotic residues tissues, organs edible products. Residual enter human body through food chain accumulate, which not only causes poisoning allergic reactions, but also drug resistance pathogenic microorganisms, thus endangering health consumers. In this investigation, 24 antibiotics, including...
Abstract Wetlands play a critical role in mitigating carbon emission. However, little is known about soil emission and their environmental controls from inland floodplain wetlands. This study aimed to determine the effects of hydrologic edaphic controllers (water table depth [ WTD ], temperature Ts water content SWC ]) on C Dongting Lake wetland, China. One‐year emissions were measured Carex meadow mudflat using static chambers during 2013 2014, including nonflooded season ( NFs ) flooded Fs...
Pigment composition is an important functional trait that can be affected by environmental factors. The objective of this study was to investigate the effect soil salinity on pigment in Suaeda salsa comparing chlorophyll and betacyanin content Liaohe estuary wetland, a typical coastal wetland northeast China. We investigated plant biomass, percentage red leaves (chlorophyll a, b betacyanins) S. intertidal supratidal zones upper, middle lower reaches wetlands. Na+ both also measured. Full...
Reconstructing chlorophyll-a (Chl-a) vertical profile is a promising approach for investigating the internal structure of marine ecosystem. Given that process classification in current process-oriented inversion methods are either too subjective or complex, novel Chl-a reconstruction method was proposed incorporating both binary tree model and Mediterranean Sea. The established based on priori knowledge provided by clustering profiles measured BGC-Argo floats performed (PCM), an advanced...
The use of large-scale tree plantations has provoked increasing concern regarding the negative effects on local environments in different ecosystems. However, physiological mechanism underlying reduction soil water by wetlands is not clear. aims this study were to investigate poplar (Populus deltoides) content and elucidate mechanisms. To end, we conducted a 1-year fixed-plot investigation (SWC), plant photosynthetic rate (Pn), stomatal conductance (Gs), transpiration (Tr), water-use...
