Adler, Robert W. | Drought, Sustainability, and the Law | Researchers and responsible officials have made considerable progress in recent years in efforts to anticipate, plan for, and respond to drought. Some of those efforts are beginning to shift from purely reactive, relief-oriented measures to programs designed to prevent or to mitigate drought impacts... | 2010-07-15 | |

Miller, Jan D. | Treatment of cyanide by using the Mexican modification of the Merrill-Crowe process | Cyanide consumption can be a major factor which contributes to operating cost for cyanidation. Also after extraction and recovery of precious metals substancial amounts of cyanide are delivered to tailings ponds which creates environmental problems due to the toxicity of cyanides. In this regard, th... | Cyanidation; Merrill-Crowe process; Air-sparged hydrocyclone; Cyanide recovery; Cyanide destruction; Chlorine dioxide | 1999 |

Sanchez, Thomas W. | Exurban and suburban residents: a departure from traditional location theory | During the 1990s, the exurban landscape grew faster and added more people than urban, suburban, and rural landscapes. In many respects, exurbanization is the quintessential representation of urban sprawl and the problems it poses. More than 100 metropolitan areas across the US attempt to manage exu... | Household location; Exurbanization; Location theory | 1997 |
