To improve heat transfer performance and reduce erosion of economizers in coal-fired power plants, firstly the heat transfer and erosion characteristics is numerically studied for the single H-type finned oval tube with enhanced heat transfer structures including bleeding dimples, longitudinal...

The grasslands of Inner Mongolia are not only the source of the necessary resources for the survival and development of herdsmen, but also represent a significant green ecological barrier in North China. Coal-mining production is important in maintaining GDP growth in Inner Mongolia. However,...

The evaluation of natural capital and environmental services has always been an important step in the implementation of sustainable development concepts and policies. The results presented in this study address the demand for environmental support of the economy of Xilinguole League in the Inner...

We study the emergence and coexistence of monetary and credit transactions in a model where exchange is decentralized. Agents belong to different villages which are informationally separated. The frequency of meetings between any two different villages decreases as their respective geographic...

The carbon emission embodied in trade is fundamental for allocation of responsibility between producers and consumers. This paper quantitatively analyzes embodied carbon emissions along the life cycle of electricity supply, based on network theory. A modified carbon emission flow model is...

The cumulative distribution of trading volume is investigated for Chinese stocks. Different from the power-law scaling of mature markets, the distribution is well fitted by a stretched exponential function f(x)∼e−αxγ. With the autocorrelation function and the detrended fluctuation...

We investigate the probability distribution of the volatility return intervals τ for the Chinese stock market. We rescale both the probability distribution Pq(τ) and the volatility return intervals τ as Pq(τ)=1/τ¯f(τ/τ¯) to obtain a uniform scaling curve for different threshold value q....
