Tree-Substrate Water Relations and Root Development in Tree Plantations Used for Mine Tailings Reclamation.
Tree water uptake relies on well-developed root systems. However, mine wastes can restrict root growth, in particular metalliferous mill tailings, which consist of the finely crushed ore that remains after valuable metals are removed. Thus, water stress could limit plantation success in reclaimed mine lands. This study evaluates the effect of substrates varying in quality (topsoil, overburden, ...
متن کاملCase History of a Copper Mine Tailings Pond Reclamation in Ducktown, Tennessee
Cessation of mining operations in Ducktown, TN, left 800-900 acres of barren copper mine tailings. Revegetation activities had met with limited success. In 1998, efforts for revegetation of the tailings materials began anew. The objective of this case history is to provide insight into decision making processes which resulted in conversion of 800-900 acres of barren mine tailings into a vegetat...

Case Presentation: A case of CVST masqueraded as high altitude cerebral edema (HACE) at 6700 m/22000 ft i...
متن کاملAthletes at High Altitude
CONTEXT Athletes at different skill levels perform strenuous physical activity at high altitude for a variety of reasons. Multiple team and endurance events are held at high altitude and may place athletes at increased risk for developing acute high altitude illness (AHAI). Training at high altitude has been a routine part of preparation for some of the high level athletes for a long time. Ther...
متن کاملThe high-altitude brain.
The highest place on our planet, Mount Everest (8850 m), appears to be close to the limit of how high an acclimatized human can go, albeit slowly. In this paper, I will explore the possibility that what limits human performance at such extreme degrees of hypoxia is the availability of oxygen to the brain. Also, one of the known costs of such extreme exposure is residual mild impairment of perfo...
