For the implementation of building information modeling (BIM), an incompatible development among various aspects a business can lead to different levels BIM maturity (BIMM) or even project failure. Therefore, it is important identify key causal factors BIMM. This research develops structural equation model BIMM through three-step multivariate analysis. It starts with exploratory factor analysis three factors, which are further tested confirmatory The relationships and then proposed validated...

Purpose – There is a growing requirement for rating system of building information modelling maturity (BIMM) to compare the effectiveness processes in construction projects. The literature related BIMM contains theoretical proposals and description their models. However, research efforts are limited lacking substantial empirical justifications. This paper unique attempt integrate previous models by performing investigations key factors measuring aims discuss these issues....

The rural three-tier healthcare system is an essential part of the Chinese service system. To ensure residents’ equal access to such services, it necessary examine current status in China and formulate corresponding improvement suggestions. This study therefore collects data from Health Statistics Yearbook, Yearbook Statistical between years 2004 2021 calculate Gini coefficient (G), health resource density index (HRDI) Theil (T) first, then perform Mann–Kendall test afterwards evaluate...

Abstract Biochar addition has been widely used in the field to mitigate soil nitrous oxide (N 2 O) emissions, and can be considered as a potential method reduce N O emissions during vermicomposting. However, excessive biochar may inhibit earthworms’ activity. Thus, it is crucial clarify optimum volumes of This study evaluated impact various amounts (0, 5, 10, 15, 20 25% total amount feedstock) on ( Eisenia fetida ) activity, emission compost quality Compared with treatment without added, 5%...

Straw return utilizes waste resources to reduce the use of chemical fertilizers worldwide. However, information is still lacking on relative impact straw soil fertility, nutrient composition different aggregates, and microbial communities. Therefore, this study aimed understand effects management practices crop yield, community in a 14-year wheat–rice rotation system. The treatments included control (without fertilizer addition), fertilization (NPK), without (S), addition with (NPKS)....

Integrating coal-to-hydrogen production with Carbon Capture, Utilization, and Storage (CCUS) is essential for reducing greenhouse gas emissions facilitating a shift towards more sustainable energy paradigm. This paper explores the diffusion of CCUS technology within sector against dynamic backdrop carbon trading market. An evolutionary game-theoretic approach utilized small-world network framework to analyze spread among enterprises. The simulation reveals that current market dynamics, along...

With the rapid growth of energy demand and increasing severity environmental pollution, low-carbon clean have become mainstream direction development. An integrated system (IES) is one effective ways to reduce pollution improve efficiency. Based on this, this paper proposes a coupled model that considers two-stage power-to-gas (P2G) carbon capture (CCS) extends it IES, including electricity, heat, gas. Then, optimization scheduling for IES based Stackelberg game established. In model,...

Salt stress has become a major limiting factor of rice (Oryza sativa L.) yield worldwide. Appropriate nitrogen application contributes to improvement in the salt tolerance rice. Here, we show that nitrogen-use efficiency increases Rice varieties with different efficiencies were subjected stress; they stimulated 50, 100, and 150 mmol/L NaCl solution at seedling stage salinities 0.2, 0.4%, 0.6% reproductive growth stage. Compared nitrogen-inefficient varieties, nitrogen-efficient showed...

The spatial distribution of hydraulic fracturing-induced seismicity is controlled by regional tectonics and local geological structures. In this study, we integrated a high-resolution shear velocity model from ambient noise imaging with 3D seismic reflection data to investigate structural influences on induced near an active fracturing (HF) platform in the Sichuan Basin, China. We conducted continuous monitoring throughout period located over 1,000 earthquakes within 7 weeks stimulation....
