To coordinate the trade-off between separation and permeation of nanofiltration membrane for Mg2+/Li+, we regulated poly(ethyleneimine)/piperazine interface polymerization parameters to construct a positively/negatively charged ultrathin Janus at free aqueous-organic interface. At optimized interfacial parameters, 0.03 wt % piperazine reacted with trimethylbenzene chloride prior poly(ethyleneimine), forming primary polyamide layer fewer defects or limiting large-scale layer. The controlled...
Global warming is a significant challenge, and carbon stocks in terrestrial ecosystems are crucial for reducing the greenhouse effect increasing sinks. A study was conducted Zhengzhou City from 2000 to 2020 using Landsat image spectral reflectance analyze changes stock. Environmental variables such as surface moisture, salinity, vegetation index, brightness, soil texture were constructed. Multiple linear regression (MLR), support vector machine (SVR), random forest (RFR), long short-term...
The quenching method is widely utilized to evaluate the contribution of reactive species; however, its validity has recently been questioned. primary role superoxide (O2•–) in pollutant degradation remains controversial due low reactivity. To ascertain suitability and ability O2•–, a simple efficient O2•– generation system was built using p-benzoquinone (p-BQ) as probe with disodium hydrogen phosphate–dimethyl sulfoxide (DHP–DMSO). results demonstrated that accountable for p-BQ...
The optical properties of hexagonal boron nitride (h-BN) thin films were studied in this paper. characterized by Fourier transform infrared spectroscopy, UV—visible transmittance and reflection spectra. h-BN with a wide band gap Eg (5.86 eV for the as-deposited film 5.97 annealed film) approaching single crystal successfully prepared radio frequency (RF) bias magnetron sputtering post-deposition annealing at 970 K. absorption behaviour accords typical characteristics amorphous materials when...
Tree species transitioning between different developmental phases requires homeostatic adjustments in order to maintain the integrity of tree hydraulic system. Hence, related traits (e.g., xylem conduit diameter) are key functional significance. However, critical information on differences stages is rare. Using sapwood samples from 36 black locust trees with growth (actively growing and declining stages) a soil water gradient along hillslope, conduits at stem apexes breast height (1.3 m...
Abstract Aims To examine chain mediating effect of discharge readiness and self‐efficacy between quality teaching self‐management in patients after percutaneous coronary intervention (PCI). Background Although PCI has significant benefits controlling risk factors delaying disease progression, the status remains unoptimistic. A large number studies have explored close relationship self‐management, but little is known about underlying mechanisms. Methods The cross‐sectional samples was...
Understanding how rainfall is partitioned into throughfall, stemflow, and interception losses by xerophytic trees important for evaluating afforestation projects modeling hydrological budgets in semi-arid regions. However, information regarding partitioning the controlling factors regions remains underrepresented literature. We examined whether plant functional groups have a significant impact on two (evergreen species: Pinus tabuliformis (Pinales:Pinaceae) hereafter called P. tabuliformis,...
It is important to clarify the impact of livelihood vulnerability level on farmers’ willingness cluster their homesteads in order promote intensive use and rural revitalization. This paper constructs a framework for influence intention homestead agglomeration, then assesses farmers based 211 questionnaire data points, analyzes agglomeration through binary logistic regression. The results showed that livelihoods had significant negative effect more vulnerable were, tendency gather residential...
Different from the principal component analysis (PCA), non-negative matrix factorization (NMF) can provide more direct interpretation owning to non-subtractive combinations of basis vectors, and many practical problems also require vectors rather than orthogonal with alternating positive negative. In this study, we develop a hyperspectral surface reflectance reconstruction method based on NMF multispectral results in several wavelength bands. order test our spectral method, datasets typical...
Abstract The slow cooling of brake assembly civil aircraft is one the major constraints on operational efficiency aircraft. Aiming at engineering problem carbon heatpacks in flight cooling, this article proposes a ventilation and scheme for assembly, which based original configuration main landing gear compartment By adding design intake duct exhaust grille, external airflow introduced to cool during flight. This confirms effect through simulation calculations experimental data. can provide...
The relationship between intelligent parking management and regional traffic congestion in the context of urban parcel renewal has attracted academic attention. Reasonable behavior analysis can effectively contribute to demand alleviate contradiction supply demand. To this end, paper constructs a multinomial logit model based on Python that considers multiple factors affecting parking. First, accommodate multi-day behavioral variability unobserved heterogeneity individual characteristics...

The hybrid nature of the mid-infrared (MIR) spectrum complicates separation reflected solar irradiance from total energy. Consequently, existing studies rarely use MIR satellite data alone for retrieving land surface temperature (LST) and emissivity (LSE). In this study, we developed What believe to be a novel physics-based approach retrieve LSE LST using channel MEdium Resolution Spectral Imager II (MERSI-II) onboard China’s new-generation polar-orbiting meteorological Fengyun-3D (FY-3D)....
Volatile organic compounds (VOCs) are common emitting substances in vehicle interior parts and materials, with a wide range of boiling points (50-250°C) polarity ranging from medium to non-polar, at least 200 species. Currently, VOC sampling mainly uses Tenax TA sorbent for collection, which has good stability is suitable weakly polar non-polar between C6-C16. But there many types substances, each substance its unique characteristics. not all it the best choice or low carbon number. In...
Abstract In this paper, four typical compounds of odorants were selected as the research objects. The mathematical model hypothesis is established which based on Weber-Fechner law, and then relationship between concentration odor substances grade verified to judge whether law applicable objective evaluation vehicle interior odor. results show that: single substance grade, two kinds are in accordance with law. It proved that conforms a certain extent, provides an important theoretical basis...
Cubic boron nitride thin films were deposited on silicon (100) substrates by sputtering. The characterized Fourier transform infrared (FTIR) spectroscopy. reflectance R(λ) of the was obtained as a function incident photon wavelengths and thickness measured Alpha-step. Using Kramers-Kronig spectrum R(λ), we calculated absorption coefficient. optical band gap found to be 5.38eV for containing 55.4% cubic phase.
