The problem of the determination of the horizontal and vertical force distributions at the base of a stockpile is a famous outstanding problem in granular theory, and has been exhaustively examined. In all past studies, the shape of the stockpile is assumed to be either a twodimensional wedge or a three-dimensional cone. Here we present the only known exact analytical solutions of the governing...

What do physicists and paparazzi have in common? They know that a picture is worth a thousand words! For this issue of the Stockpile Stewardship Quarterly, the theme is advances in imaging diagnostics. Not only do the images tell a story, as asserted in the old axiom, about the dynamics of high-explosives, laser or pulsed power-driven events, but they are also becoming very quantitative. The qu...

Dust emissions can have significant effects on the human health, environment and industry equipment. Understanding the dust generation process helps to select a suitable dust preventing approach and also is useful to evaluate the environmental impact of dust emission. To describe these processes, numerical methods such as Computational Fluid Dynamics (CFD) are widely used, however nowadays part...

The recognition of the importance of entrepreneurial dynamics in corporate context is increasingly acknowledged in both entrepreneurship and strategic management literature, as firms today face a reality in which frame-breaking innovation is an important element of survival. From this understanding, the concept of Strategic Entrepreneurship (se) has arisen, arguing a logic of focusing on the in...

The open-pit mine production scheduling problem has received a great deal of attention in recent years, both in the academic literature, and in the mining industry. Optimization approaches to strategic planning for mine exploitation have become the industry standard, as the recent review of Newman et al. [19] highlights. However most of these approaches focus on extraction sequencing, and don’t...

There has been much attention paid to oil security in China in recent years. Although China has begun to establish its own strategic petroleum reserve (SPR) to prevent potential losses caused by oil supply interruptions, the system aiming to ensure China's oil security is still incomplete. This paper describes and provides evidence for the benefits of an auxiliary strategic oil policy choice, w...
