The results show that...

A rapid method has been developed based on the sample preparation procedure named as QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe), combined with reversed-phase high performance liquid chromatography fluorescence detector C18 column after pre-column derivatization using o-phthalaldehyde 2-mercaptoethanol to determine dopamine in porcine muscle. Methanol deionized water (0.1% acetic acid, v/v) a ratio of 60:40 was used mobile phase. The flow rate 0.8 mL/min eluted within 15 min....

Parabens, triclosan (TCS), triclocarban (TCC), and bisphenol A its analogues (BPs) are used in various industrial consumer products typical endocrine-disrupting chemicals (EDCs). In this study, six parabens, TCS, TCC, eight BPs were determined 289 indoor dusts collected from different geographical regions China. Ten of 16 target compounds found >50% samples. Concentrations Σ6parabens, Σ(TCS+TCC), Σ8BPs dust ranged 8.66-21,500 (median: 288), 19.6-8940 (104), 8.80-37,400 (377) ng/g dw,...

Rationale: To retrospectively analyze serial chest CT and clinical features in patients with coronavirus disease 2019 (COVID-19) for the assessment of temporal changes to investigate how differ survivors nonsurvivors. Methods: The consecutive records 93 confirmed COVID-19 who were admitted Wuhan Union Hospital from January 10, 2020, February 22, reviewed. A series findings data collected analyzed. scans scored on a semiquantitative basis according extent pulmonary abnormalities. Chest scores...

The outbreak of the novel coronavirus 2019 (COVID-19) pandemic has resulted in increased human consumption medicines. Antibiotics are great concern due to their adverse effects, such as bacterial resistance and dysbiosis gut microbiota. Nevertheless, very little is known about changes self-medication with antibiotics during COVID-19 resultant potential health risks. Herein, we examined concentration profiles some commonly used urine collected from several geographical regions China between...

Tourism is important in that protected areas (PAs) provide cultural ecosystem services. However, interactions between humans and nature, stakeholders, environmental elements make it complex variable. To promote sustainable tourism development PAs, this study (i) established an evaluation framework reflecting the relationships among stakeholders different system dimensions considering human–environment systems' complexities, dynamics, interactivity, (ii) identified 52 sustainability...

Outdoor tourism can provide nature therapies. Implementation research for mental healthcare aims to establish psychological mechanisms and specify designs, doses durations medical trials. As one component, we tested simultaneous links from senses emotions, emotions self-perceived wellbeing, 524 tourists at 27 forest reserves in China. We used quantitative surveys, person, with: 5-point Likert-type scales measure links; free-text descriptions of their most memorable sensory emotional...

A conceptual network between and among tourist engagement, perceived value, satisfaction, destination loyalty was constructed validated based on 401 valid samples collected in Phoenix Ancient Town, a famous western Hunan, China. The research results confirm the logic chain marketing psychology of “engagement-value-evaluation/behavior” context tourism destination. Specifically, engagement has direct positive effects loyalty, but not satisfaction. In addition, exerts indirect by producing...

Natural environment has a positive effect on individual mental health, which can be proved by many studies, both domestic and overseas. At present, some sunrise industries such as forest healthcare natural tourism are booming in China. However, academically speaking, there’s still lack of systematic summary researches the relationship between health China, well comparison with foreign research achievements, hinders further development field to extent Therefore, this paper reviews literature...

Tourism development efficiency is one of the key scales to measure quality tourism destination. This study improves existing input–output index system evaluation; knowledge innovation introduced into input index, and environmental health pressure output index. Based on case Hainan Island, we used EBM model compatible with radial non-radial data evaluate efficiency. In order make up deficiency spatial effect analysis based geographical distance weight matrix, spillover in Island was analyzed...

Cities are of wide concern to scholars due their major share global carbon emissions. Energy-related emissions differ significantly among cities, especially megacities, regional heterogeneity in socioeconomic conditions. To analyze the differences influencing factors on within and further target emission reductions, measures were developed. Beijing was selected investigate factor core zones, developing zones ecological using STIRPAT model county level. The results show following: (1)...

In fractal theory, the dimension has been accepted as a quantitative parameter to measure complexity of fluctuations and persistence wind speeds. Typhoons are extreme events that damage structures. this study, on basis field measurements, characteristics four typhoons in southeastern China examined. Typhoon speeds at different heights locations presented. Monofractal analysis was first conducted, results revealed typhoon were persistent, with dimensions smaller than 1.5. For all considered,...

This pioneering study examined the complex interplay between climate changes and landscape ecological dynamics through a spatiotemporal analysis (1980–2023) of China’s climatically vulnerable Qinling Mountains. The results revealed significant trends in indices, indicating ecosystem sensitivity Mountains to change. temperature precipitation as primary climatic drivers differentially affecting land cover systems. Qinling’s thermal regime has undergone progressive intensification under...

The homestay business has contributed to the development of tourism industry, and it revitalized resources boosted economy. This article takes Mogan Mountain agglomeration Yangtze River Delta, most developed actively invested in as a research site focus discuss recent trends Chinese business. Standard deviational ellipse analysis, spatial analysis nearest-neighbor, density are empirically tested with data from inn/homestay channel Qunar.com, which is widely acclaimed website high page views....

Improving the coupling coordination degree between water and land resources matching (WLRM) cultivated use eco-efficiency (CLUE) is crucial to ensuring national food security constructing an ecological civilization. This study based on data of 71 prefecture-level cities in major grain-producing areas middle lower reaches Yangtze River from 2008 2020. The unit area resource method, slacks-based measurement (SBM)-undesirable, Theil–Sen median analysis, Mann–Kendall trend test, model, spatial...

The assessment of suitability is the cornerstone for development ecotourism in nature reserves. This paper adopts Delphi method to invite 30 experts score and screen a series indicators then calculates weight each indicator through hierarchical analysis (AHP) establish comprehensive evaluation index system development.
