Abstract

Purpose

The purpose of this paper is to examine the impacts of capital regulation and market discipline when China imposed most of the Basel I requirements between 2004 and 2010.

Design/methodology/approach

Following Barrios and Blanco (2003) and Rime (2001), the authors apply disequilibrium and simultaneous measurements to identify the financial safety net underlying capital movements as well as the changes in credit risk levels in China’s banking sector.

Findings

The authors discover that capital regulation outweighs market discipline by an average probability of 0.65-0.35 in the contribution to bank capital movements when banks significantly improve their capital buffers. In addition, the banking sector lowered its risk levels in the sample period.

Research limitations/implications

The findings suggest that the largest bank-based economy has consolidated its financial system for future expansion.

Originality/value

China’s banking sector requires closer examination of capital and risks provided by its emerging significance in the financial world. Thus, this study contributes to current literature.

Abstract

Purpose

The purpose of this paper is to quantify the influence of alternating current (AC) interference on hydrogen evolution reaction of X80 steel.

Design/methodology/approach

The hydrogen evolution potential was obtained by cathodic potentiodynamic polarization curve. The instantaneous potential under AC interference was obtained by high-frequency acquisition with three-electrode system. Electrochemical impedance spectroscopy and Tafel polarization curves were used to study the influence mechanism of AC interference on instantaneous potential.

Findings

It was concluded that the hydrogen evolution reaction could occur on X80 steel under AC interference. There were critical AC current densities of about 100 to 200 A/m2, beyond which the cathode reaction of X80 steel changed from oxygen absorption to hydrogen evolution. Besides the pH value, the initial polarization potential EZ and impedance module of the steel/electrolyte interface under AC interference were also the factors that affected the critical AC densities in different solutions.

Originality/value

This research quantified the hydrogen evolution capacity of X80 steel under AC interference, which could be applied to clear the effect of AC interference on hydrogen evolution reaction.

Abstract

Purpose

The purpose of this paper is to propose a new yield function for granular materials based on microstructures.

Design/methodology/approach

A biaxial compression test on granular materials under different stress paths is numerically simulated by distinct element method. A microstructure parameter S that considers both the arrangement of granular particles and the inter-particle contact forces is proposed. The evolution of the microstructure parameter S under the simulated stress paths is analyzed, from which a yield function for granular materials is derived. The way of determining the two parameters involved in the yield function is proposed.

Findings

The new yield function is calibrated using the test data of one sand and two rockfill materials. The shape of the new yield surface is similar to that of the Cam-clay model.

Originality/value

The paper proposes a microstructure parameter S, which considers both the arrangement of granular particles and the inter-particle contact forces. From the evolution of S, a yield function for granular materials is derived. The proposed yield function has a simple structure and the parameters are easy to be determined, leading to a feasible realization of engineering application.

Abstract

China is among one of the oldest civilizations in the world. The massive land mass of China also means that the Chinese people are subject to weather extremes as well as topographical variety in a country which cuts across alpine heights, treacherous deserts, lush valleys, dusty plains and lengthy rivers. With these weather extremes as the backdrop, it is crucial for the Chinese people to develop appropriate environmental control techniques for their dwellings as well as to ensure the structural integrity of their buildings. This paper discusses the protection, heating, anti‐seismic and dampness techniques developed and implemented in ancient China. It also documents the measures taken by the ancient Chinese to ensure the structural integrity of their buildings. The examples highlighted in this paper suggest that the building science principles adopted in ancient China remain relevant in the construction industry today.
