iran is located in a high-risk seismic zone of earthquakes. it has thousands of valuable historic buildings, mostly made of unreinforced masonry, which is quite vulnerable to natural hazards, especially earthquakes. the conservation and seismic upgrading of these buildings is vital for their survival. however, resources are limited and some sort of prioritization is needed in order to allocate ...

Global Positioning Systems are becoming increasingly pervasive. The forensic acquisition and analysis of these units is of great interest as it has the potential to yield historic locational data for these units. Analysis of the TomTom one satellite navigation unit has resulted in a method to reliably extract historic data from these devices in a forensically sound manner.

Livestock grazing is the most ubiquitous land use in western North America, yet it rarely has been studied in a controlled manner because of the lack of large areas free of grazing. We compared the ecological effects of three grazing treatments—long-term protection, short-term protection, and currently grazed—at Chaco Culture National Historic Park in northern New Mexico. Chaco has a long histo...
