Any undisturbed rock mass is subject to natural stresses inclu ding gravitational stresses due to the mass of the overburden and possibly tectonic stresses due to the straining of the earth's crust and remanent stresses due to past tectonism. Knowledge of the in situ stress field must be integrated into any rock engineering design along with general rock mass characteristics such as de for mability, strength, permeability and time dependent behavior. For example, the choice of optimum orientation and shape of deep underground caverns or complex underground works will be controlled by the...

This book makes the case for a systems approach to small-scale community development projects. It specifically looks at the application of one branch of systems science, called system dynamics, to develop conceptual models of small-scale communities and address specific issues they might be facing at different scales. A systems approach recognizes that, by definition, communities are complex adaptive systems consisting of multiple subsystems and parts (e.g., individuals, institutions, and infrastructure) that are interconnected, driven by some purpose, follow certain rules, and interact...
