This paper examines the relationships among environmental regulations (ER), staff quality (SQ), R&D efficiency (RDE), green technology (GT), and profit. The research sample comprises 1197 firms in 16 manufacturing industries China, during 2008 2015. DEA-based measures are employed to firm RDEs, results show that SQ is essential for high RDE GT (as expected), but main effects of mixed. Importantly, we find ER moderates SQ-GT, SQ-RDE SQ-profit relationships. Specifically, if ERs eased, limited...

The Beijing–Hangzhou Grand Canal is renowned for being one of the longest and largest canals in world. Running from Beijing to Hangzhou (north south), it connects China’s five major water systems has an important impact on ecological environment economy northern southern China. It also boasts a large quantity intangible cultural heritage (ICH). Clarifying spatio-temporal distribution pattern ICH Basin its influencing factors essential protection utilization resources formulation management...

Abstract Background Previous research suggested an association between maternal exposure to ambient air pollutants and the risk of congenital heart disease (CHD). However, effect individual prenatal indoor on CHD occurrence was not reported. Methods We performed a hospital-based case–control study investigate personal pollution during pregnancy in offspring. A total 44 cases 75 controls were included from two hospitals East China. investigated residential environmental characteristics using...

In this study, we evaluate the effect of co-doping with TiO2 nanoparticles and sisal cellulose nanocrystals (CNCs) on physical biological properties a conventional glass-ionomer cement (GIC). Test samples were characterized by scanning electron microscopy, Fourier-transform infrared spectroscopy, subjected to mechanical tests performances. Antimicrobial activity was evaluated against Candida albicans, cytotoxicity experiments conducted using L-929 cells. Unmodified GIC served as control....

Kelp, the brown alga distributed in coastal areas all over world, is also an important medicine food homology product China. However, levels and profiles of persistent organic pollutants (POPs) kelp have not been thoroughly investigated to date. Polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) emerging bromine flame retardants (eBFRs) were evaluated 41 samples from main producing The concentrations total PCBs, PBDEs eBFRs range 0.321–4.24 ng/g dry weight (dw),...

Our LC-HRMS method enabled analysis of 54 dye components in hair samples, outperforming the standard speed, stability, accuracy, isomer separation, sensitivities, and resolution filtration adsorption.

Congenital heart disease (CHD) is a common birth defect. Our previous studies suggest that indoor air pollution, especially total volatile organic compounds (TVOCs), may increase fetal CHD risk, whereas vitamin and folic acid (FA) supplements in early pregnancy might offer protection against CHD. However, limited research has explored whether FA or multivitamin supplementation can mitigate the effects of TVOCs exposure on We conducted case-control study to investigate association between...

The urban transit system is considered the backbone of any society as it heavily depends on economic progress. railway crucial for system. Based this notion, present research explores industrial agglomeration in China’s prefecture-level and cities from 2010 to 2020. analyses processes rail building, agglomeration, labor due railway’s network development. findings are summarized three main points; first, force positively affected by construction infrastructure. Secondly, development railways...

Purpose: To evaluate the clinical effectiveness and safety of bioresorbable implants for treating paediatric zygomaticomaxillary complex (ZMC) fractures with concomitant orbital floor defects. Methods: A retrospective review patients who underwent ZMC repair in Shanghai Ninth People’s Hospital from July 2015 to June 2019 was performed. The primary outcome measures included ocular motility, diplopia, enophthalmos, facial deformities, restricted mouth opening, as well complication rates. Pre-...

Air pollution is a global problem and the transportation industry one of its major causes, yet impact infrastructure on air quality little understood. It vital to know about evaluating effects quality. The urban road has role in defining automobiles significantly contribute areas. issues are result automobile’s China put substantial investments metropolitan subway networks. information an hourly basis, daily metrological data, demographic profiles various cities with significant subways from...

Under environment, there are new changes business models marketing channel, grasp these improvement China’s enterprise management channel strategy will help enterprises to achieve “going out” goals. Key words: Network economy; Enterprises operating mode; Marketing channels

Objective: To investigate the situation of health emergency human resources in disease prevention and control institutions to provide scientific basis policy recommendations for rational allocation institutions.Methods: questionnaire was used collect personal data personnel Henan province institutions.Results: 2729 existing personnel, institutions, including technical accounting 80.73% management 19.27%; age structure is fusiform, with 35-44 group, 38.77% (1058 /2 729); junior college...

Here, we identified 17 elements in samples of the important Tibetan medicinal herb Gentiana straminea, which were collected from 28 different locations throughout Qinghai Plateau China.The dissolved HNO3 and H2O2 for inductively coupled plasma-atomic emission spectrometry (ICP-AES) analysis.For each element, analysis lines with highest sensitivity lowest interference spectrums chosen.Recovery ranged 93 to 106 %, indicating accuracy analysis.The mean concentrations as follows:Quantitative was...

In this paper agricultural technology innovation resources and their allocation efficiency was defined, according to the characteristics of stage process, an evaluation index system output conversion is set up. Using a two-stage DEA (data envelopment analysis) model, upon continuous 17 years in China are analyzed evaluated. Then reason inefficient found out, corresponding improvement suggestion proposed.
