The contribution of mountains to global denudation
The hypothesis that mountains infl uence global climate through links among rock uplift, physical and chemical denudation, and the carbon cycle remains vigorously debated. We address the contribution of mountains to global denudation with an empirical model that predicts that >50% of the total denudation and 40% of the chemical denudation occur on the steepest ~10% of Earth’s terrestrial surfac...
متن کاملNEUROGENIC HYPERTENSION: REPORT OF FIVE CASES TO HIGHLIGHT THE CONTROVERSY
The entity of "neurogenic hypertension" is defined as arterial hypertension caused explicitly by derangement of the intricate network of the central nervous system. Among 193 cases of cranial rhizopathies operated on between 1984 and 1995 at this center, 5 cases of established arterial hypertension with concomitant rhizopathies also underwent ventrolateral medullary decompression. The elev...
متن کاملGeomorphic Controls on Andean Denudation Rates
To predict erosion rates throughout the Andes, we conducted a multiple regression analysis of the sediment discharge from 47 drainage basins in the Bolivian Andes and various topographic, climatologic, and geologic parameters. These mountainous basins are typically large (17–81,000 km; km), often have decades of measurement mean p 11,000 data on daily water and sediment discharge, and display a...
متن کاملThe cigarette controversy.
This study examines the history of the cigarette controversy using the tobacco documents as a roadmap to explore the following four questions: (a) What did tobacco companies know about the health risks of smoking and when did they know it?

متن کاملDeciphering the MSG controversy.
Monosodium glutamate (MSG), a common flavor enhancer in various canned food and stereotypically associated with food in Chinese restaurants, has been claimed and tested to have side effects including headache and dizziness. However, the mechanism behind MSG-induced headache was not clear. Using dissociated mouse neuronal culture and cell injury assays, we determined whether incubation of neuron...
