... Atmospheric nitrate (NO₃⁻) produced by photochemical oxidation in the atmosphere has high oxygen isotope ratios (δ¹⁸O values). Recently, the primary NO₃⁻ emitted from combustion sources was found to have much lower δ¹⁸O values. However, it is unclear how and to what extents the low δ¹⁸O signatures were controlled by major O sources during the primary NO₃⁻ formation of combustion processes. Here, w ...
... The yogurt adherence always caused enormous waste of food sources due to sticking onto the package inner walls. So, carnauba wax, silica, and carboxymethylcellulose (CMC) were mixed together as an emulsion to be sprayed, and fabricated an edible special wettability coating on the polystyrene substrate for reducing the yogurt residual rate. The contact angle, slide angle and yogurt residual rate on ...

Abstract:
... Phytosterol (PS)/whey protein isolate (WPI) self-assembly complex was formed with different PS:WPI mass ratios (from 1:1 to 1:15) to reveal the relationship of interaction mechanism in PS/WPI complex, WPI secondary structure, and PS digestion properties. The sample with 1:5 mass ratio had the strongest hydrogen bonds and the largest encapsulation efficiency (EE). Circular dichroism analysis indica ...
... Apocynum venetum L. flowers are the source of beverage and primary nectar with potential industrial value but have received less attention. This study aimed to investigate its processing, chemical characterization and quality evaluation of the potential antidiabetic activity. Compared with heat reflux extraction, the ultrasound-assisted extraction (UAE) method had the advantages of low cost and hi ...

Abstract:
... In this study, we compared the incidence of postharvest disease and the storage potential of blueberry fruit treated with thymol (inoculated with Aspergillus niger) with those in the control fruit during storage for 42 d at 2 °C. Treatment with 10–30 mg/L thymol was found to be more effective than treatment with higher thymol concentrations of 40–50 mg/L in terms of controlling Aspergillus niger-i ...
... On the basis of our qualitative analysis, two new methods of the resonance Rayleigh scattering (RRS) and multiwavelength visible absorption spectroscopy (VIS) for the determination of curcumin in dried ginger are established. At pH 6.70 Tris-HCl, curcumin reacts with brilliant green to form binary ionic association complexes. Curcumin was determined by the RRS method at 347 nm, and the detection l ...

Abstract:
... More recently, the COVID-19 pandemic outbreak has created massive economic policy uncertainty (EPU). EPU and its economic fallout have been a hot topic of study; however, the impact of EPU on CO₂ emissions has been seldom addressed to date. This paper investigates the effects of the EPU on CO₂ emissions. It elucidates the role of EPU in moderating the environmental regulation-CO₂ emissions nexus a ...
... Syngas, containing mostly CO and H₂, has variant explosion properties for the specific contents. For a further understanding, a comparative study on the turbulent explosion characteristics of syngas between CO-enriched (the mole ratio of CO was 70%) and H₂-enriched (the mole ratio of H₂ was 70%) were conducted at different equivalence ratios (φ, from 0.4 to 3.0) and turbulent intensities (u'ᵣₘₛ, f ...
... BeiDou Global Navigation Satellite System (BDS-3) provides a regional Precise Point Positioning (PPP) service, called PPP-B2b, for users in China and surrounding areas through B2b signal transmitted from its three geostationary earth orbit (GEO) satellites. The information broadcasted by the B2b signal include satellite orbit corrections, satellite clock offset corrections, and differential code b ...

Abstract:
... An algae photobioreactor (APB) was used to determine the effect of water recirculation on the growth of algal assemblage. CO₂ in the flue gas from a power plant was the carbon source. Boiler water was used as the source water. The results showed that microalgae cultivation under recirculation conditions was stable over a period of four months. Biomass productivities during the 1ˢᵗ through 4ᵗʰ mont ...
ammonium; biomass; nitrates; pollution; soil; urbanization; China
Abstract:
... The elevation of nitrogen (N) deposition by urbanization profoundly impacts the structure and function of surrounding forest ecosystems. Plants are major biomass sinks of external N inputs into forests. Yet, the N-use strategies of forest plants in many areas remain unconstrained in city areas, so their responses and adapting mechanisms to the elevated N deposition are open questions. Here we inve ...
... To investigate the effects of transmembrane protein 45A (TMEM45A) on biological characteristics and cisplatin (DDP) resistance of cervical cancer cells. TMEM45A in cervical cancer cells and normal cervical epithelial cells (HCerEpiC) were quantified by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting. HPV genotypes were identified by multiplex PCR. SiHa and HeLa cell ...
data collection; energy efficiency; solar radiation; China
Abstract:
... Solar radiation is a crucial parameter that affects the thermal environment in buildings. The spatial and temporal distributions of solar radiation data are important for energy-efficient building design. Models that correlate solar radiation with other parameters can address the lack of solar radiation data. Satellite-derived products and reanalysis data sets have been produced using solar radiat ...

Abstract:
... The rapidly increasing availability of agricultural machinery services in rural China may promote development in the farmland rental market, but it can also hamper it. This study provides a theoretical and empirical examination of how and to what extent agricultural machinery services affect the participation of smallholders in farmland rental markets. In the theoretical part, a price band model f ...

Abstract:
... Orthodontic tooth movement mainly depends on biological and mechanical reactions in the periodontium, such as the indispensable reconstruction process of the periodontal ligament and alveolar bone. To explore whether orthodontic compressive force can induce bone resorption during orthodontic tooth movement by regulating the GSK-3β/β-catenin pathway. We established orthodontic tooth movement models ...

Abstract:
... Public transit stations are places that are known to generate opportunities for crime. By spatially integrating crime data, smart card data and census data along with information from OpenStreetMap and Queensland Rail, we apply multilevel negative binomial regression models to examine the role of passenger presence on the three most common types of crime at train stations in Brisbane, Australia. T ...
... This paper aims to synthesis a recyclable adsorbent from solid waste using a clean and environmentally friendly method to deal with Cr(VI) water pollution. Magnetic zeolite/chitosan composites (ZFA/MCS) were prepared by the neutralization method. The adsorption properties of ZFA/MCS, prepared by the neutralization method for Cr(VI) ions under different conditions especially cross-linking, were inv ...
... Quantifying uncertainties in water resource prediction in data-scarce regions is essential for resource development. We use globally available datasets of precipitation and potential evapotranspiration for the regionalization of model parameters in the data-scarce regions of Ethiopia. A regional model was developed based on 14 gauged catchments. Three possible parameter sets were tested for region ...
... A high level of sugar intake has been linked to poor dietary quality and a wide range of chronic diseases. However, data on sugar intake are still scarce in China. This study aimed to provide time trends in the total and added sugar intakes among Chinese children and adolescents from 1997 to 2011. A nationwide ongoing open prospective cohort study of Chinese children and adolescents aged 3–17 year ...

Abstract:
... In practice, urban and regional planners often use a pixel-based method for image classification. Unfortunately, it produces lower accuracy than an Object-Based Image Analysis (OBIA) method, especially for the high-resolution images. To assess spatial planning, scholars rarely used the OBIA method in open-source software. This paper aims to develop a method for classifying land cover and assessing ...
