This map shows all the places conservation elements. Some of the places included exhibit high biodiversity or ecological and cultural value. This map also shows other managed areas from the Protected Areas Database, as well as those that are excluded. Associated input datasets are also included; they relate to biodiversity, special areas, and development. These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions. The User assumes the entire risk associated with its use of these data and bears all responsibility in determining whether these data are fit for the User's intended use. These data may not have the accuracy, resolution, completeness, timeliness, or other characteristics...
Mining and civil engineering industries sometimes use drilling muds for stabilizing a borehole during drilling wells for methane drainage, geothermal energy and radioactive waste disposal. Standard theories predicting borehole breakdown pressure assume breakdown occurs when a small fracture initiates at a location where the largest tangential stress at the borehole reaches the tensile strength of formation. Fracturing tests conducted in this study, how- ever, showed that when drilling fluid was used as an injection fluid, borehole breakdown did not occur even if a fracture initiated at a borehole wall. Bore- hole breakdown occurred when the initiated fracture became unstable after significant growth with O. 76cm...

These data identify, in general, the areas where final critical habitat for California red-legged frog (rana aurora draytonii) occur.
We propose a model for an exhausted upper continental crust. The Crepuscular Earth represents a degraded planet where all resources have been extracted and dispersed, and all fossil fuels have been burned. The starting point of the model of crepuscular crust is the composition given by the geochemist Grigor’ev, which is constrained by the conservation of mass statement between the chemical composition of the crust in terms of elements and in terms of minerals. Additionally, the model is given geological consistence, by introducing a series of assumptions based on geological observations. As a result, the obtained crepuscular crust is composed of the 294 most abundant minerals. Together with the model of exhausted...
