Abstract:

Water issue is one of the challenges of urban sustainability in developing countries. To address the conflict between urban water use and economic development, it is required to better understand the decoupling states between them and the driving forces behind these decoupling states. The transformed Tapio decoupling model is applied in this paper to study the decoupling relationship between urban industrial water consumption and economic growth in Beijing and Shanghai, two megacities in China, in 2003–2016. The factors driving decoupling are divided into industrial structure effect, industria

Abstract:

Residential energy consumption (REC) is now the second largest energy sector in China. However, decoupling analysis of REC has not received enough attention. Here, we explore the decoupling relationship between REC and economic growth in urban and rural Guangdong from 2000 to 2017. First, we use the Tapio decoupling model to study the decoupling state. Then, key drivers affecting the decoupling were explored by combining the Tapio decoupling model with the Log-mean Divisa Index (LMDI) method. Finally, the decoupling efforts were evaluated by using the decoupling efforts model. The main results

Abstract:

Abstract To analyze the influence of radial decoupling parameters on the blasting effect of limestone, finite element analysis was established using ANSYS/ls-dyna to analyze the effects of different radial decoupling coefficients and different media on blasting. Research has found that limestone has more cracks and more pronounced cracking when air is uncoupled. Under the condition of air decoupling, the stress waves in the rock mass are more concentrated and have higher energy, while under the condition of water decoupling, the stress waves in the rock mass diffuse faster, have a larger range

Purpose - Although many existing studies on the US-China hegemonic conflict and decoupling have been published, most of them are qualitative and use descriptive analysis methods. Papers that quantitatively analyzed decoupling mainly estimate the effect of a tariff increase. However, this paper quantitatively analyzed the ripple effect by focusing on decoupling technology spillover between the United States and China. And, for the first time, it was suggested that the blocking of technology spillover could give a fatal blow to the East Asian economy as well as China. Design/methodology -

Abstract:

Magnetic liquid double suspension bearing (MLDSB) is composed of an electromagnetic system and hydrostatic system and its bearing capacity and stiffness can be greatly improved. It is very suitable for occasions of medium speed, heavy load, and starting frequently. Due to the gyroscopic effect and interference between the supporting system, the space state of the rotor can be affected and the operation stability of the MLDSB can be reduced greatly. Therefore, the coupling features of the multi-degree of freedom (multi-DOF) system are analyzed and a decoupling controller is designed and verifie

Abstract:

The development of digital economy is conducive to empowering technological innovation and optimizing industrial structure, thus reducing the environmental pollution caused by industrial development. However, the development of digital economy also implies an increase in energy demand. Whether its impact on CO2 emissions is the same as or opposite to the Kuznets hypothesis in a “U-shaped” or “N-shaped” relationship, and whether there is a decoupling effect between the two, deserves further study. In this paper, we analyze the non-linear impact of digital economy on carbon emissions through lit

Abstract:

As the six central provinces account for 23% of total national carbon emissions (CE), research into the decoupling status of their economic growth (EG) and carbon emissions is critical to achieving the Dual Carbon Goals and the Rise of Central China Plan. This research initially examines the decoupling status between CE and EG using the Tapio decoupling model, based on energy consumption (EC) dataset from six central provinces in China between 2000 and 2019. The decoupling index (DI) is then divided into five decoupling drivers using the LMDI method. Finally, an enhanced STIRPAT model is used

Abstract:

In the process of studying the issues of ecological and economic interaction, the so-called “decoupling” is increasingly becoming one of the defining concepts. Decoupling implies the elimination of the contradiction between the possibilities of ensuring economic growth and reducing the level of environmental impact. The most significant field of economic activity is an agrifood production. In the scope of reducing the consumption of natural resources, achieving the decoupling effect is fundamentally essential. In this regard, the paper based on the author’s methodological approach assesses the

Abstract:

Efficient heteronuclear decoupling is essential to obtain high-resolution NMR spectra of organic and biological solids containing protons and low-gamma nuclei such as carbon-13. All modern decoupling sequences employ pulse lengths that are optimized for a given radio-frequency (rf) power. However, there is an unavoidable distribution of rf field amplitudes across the volume of the sample. Inevitably, the effect of the rf field distribution manifests itself for fully packed rotors during any decoupling irradiation. In this study we present a detailed analysis of the effect of the inherent rf fi
