Understanding the complex relationship between ecosystem services and human well-being during rapid development of urban agglomerations can promote sustainable agglomerations. In this paper, InVEST model ArcGIS10.2 were used to analyze spatial temporal evolution characteristics in Guanzhong Plain agglomeration. On basis, coupling coordination index is reveal spatiotemporal them. (1) From 2010 2018, water conservation services, soil carbon sequestration agglomeration showed a fluctuating...
Detection of heavy metal residues in herbal medicines by a high-sensitivity X-ray fluorescence method that couples monochromatic excitation energy dispersive spectrometry and the fast fundamental parameters method.
Panax notoginseng is an important functional health product, and has been used worldwide because of a wide range pharmacological activities, which the taproot main edible or medicinal part. However, technologies for origin discrimination still need to be further studied. In this study, ICP-MS/MS method accurate determination 49 elements was established, whereby instrumental detection limits (LODs) were between 0.0003 7.716 mg/kg, whereas quantification (LOQs) 0.0011 25.7202 recovery in...
The unclear environmental performance of nonivamide limits its application as a marine antifoulant. In this study, the natural degradation was studied in seawater and tap water. half-life 5.8 d, 8.8 12.2 14.7 d water photolysis biolysis, respectively.

Understanding solute transport through macroscopic interfaces is essential to understand the effects of geological heterogeneity on contaminant in porous media. Studies compartmental media have noted asymmetry breakthroughs (BTCs) movement across material interfaces, indicating presence discontinuous concentration that makes directionally dependent. Transition are more common nature than sharp interfaces. To transition well-controlled laboratory experiments were performed. A numerical model...
The effect of acidic pH conditions on the physiological response three typical freshwater algae, Chlorella vulgaris, Microcystis aeruginosa and Scenedesmus quadricauda, was investigated in this study. results cultivation experiment indicated that mortality algae logarithmic growth phase increased with increasing exposure time acidity under acute conditions. tolerance S. quadricauda stronger than other two species long-term (6 h) to same acidity; contrast, C. vulgaris exhibited greatest...
This study investigated the feasibility of distance protection in extra-high voltage (EHV) networks. In long-distance transmission lines, distributed parameter characteristic EHV network is obvious. When a fault occurs far away from measurement site, measured impedance might not be directly proportional to distance, and domain will decreased. The detailed theory inferred proven this paper reveals that phenomenon widespread lines. results indicate error greatly reduced by application shunt...
Nitrous oxide (N 2 O) is a powerful greenhouse gas that degrades ozone. Hypoxia and ocean acidification are becoming more intense as result of climate change. The former stimulates N O emissions, whereas the effects latter on production vary by ocean. may play critical role in evolution future oceanic production. However, interactive hypoxia remain unclear. We conducted research cruise Bohai Sea China to assess occurrence seasonal oxygen minimum zone sea further laboratory incubation...
Due to the characteristic of dual feed-back paths in fully differential amplifier, a software-defined radio (SDR) oriented approach constructing RF front-end circuit with amplifier is presented. By small signal mode feedback loops, detailed input and output relationship this kind deduced. Thereby, transfer function symmetrical loops noise formula nonsymmetrical are both derived. An optimized termination also introduced make more suitable for high-speed wideband system. The proposed method...
In the gate-last scheme, inter-layer dielectric level zero (ILD0) chemical mechanical polishing (CMP) for replacing metal gate (RMG) application has been developed to meet criteria of high-k (HKMG) devices at 28nm technology node. The height uniformity, loading and dishing performance control are important process challenges. However, opening poly-Si is principal factor in construction HKMG. Moreover, it's a single-plank bridge that dummy can be removed deposit work function aluminum metal....
The Silicon Carbide (SiC) module has been rated as one of the most promising power electronic devices due to its excellent performance in reducing loss. However, reliability SiC is seriously influenced by thermal stress, and control proven a cost-effective mean reduce stress. This paper proposes method design temperature target based on feedback lifetime. We show that chosen can optimize control. Case studies experiments are given demonstrate this method. Results consumed lifetime reduced...
As for energy storage system, power converter is one of the most significant components. However, repetitive thermal stress leads to great concern reliability, this because variation generation and demand. This paper proposed assess reliability in system with data long-term load solar irradiance. Our research shows that IGBT more easily fail than Diode system. Additionally, effect junction temperature swing low frequency, triggered by mission profile variation, bring a high degree consumed...
A simple method using Chelex-100 chelating resin and Atomic Absorbance Spectroscopy determination of lead, cadmium copper in high-salt food was established. This could solve the problem interference on lead salt matrix. Kd values sodium (Na), (Pb), (Cd) (Cu) measured. The influence pH solution absorption behavior ions were investigated. Elution curve for Na Cd demonstrated. Absorption capacities to Pb/Cd/Cu/Na determined. developed applied analysis samples. recoveries range 91.6%~98.6% with...
