众所周知,高血压会引起冠心病,而冠心病则是目前导致人类死亡的主要原因之一.虽然平时我们没有听说某某人死于高血压,但是,高血压是慕后的"罪魁祸首",它所导致的许多疾病对人类而言是致命的.然而,高血压之"高"的标准在全世界是否能够或者应该"一刀切"?换言之,同样水平的高血压,所导致的冠心病的死亡率是否相同呢?回答似乎应该是Yes.可是,本文的回答却是"
The high-pressure structure and physical properties of RbNO3 at zero temperature was systematically explored using first-principles calculations based on density generalized theory combined with CALYPSO crystal structure predictions. The accur
Nature-based tourism Tourism pressure Protected area Social big data Management policy 1. Introduction Nature-Based Tourism (NBT) in protected areas is an easily experienced ecosystem services provided to mankind (Balmford et al., 2015). Protected areas are the preferred ecotourism destinations that ...
The Mediterranean region is subject to the influences of both subtropical circulation and the prevailing sub-polar-frontal low-pressure systems11, which exhibit substantial variation in position and intensity over annual and decadal time scales13. Anthropogenic forcing is thought to have the potential to...
The vegetation of the upper Dades catchment is relatively sparse, which is due to the climatic conditions and also due to high degree of anthropopressure (by grazing and subsistence use for firewood). The slopes are predominantly covered by sparse low shrub vegetation, mainly of specimens of Lami...
Seasonal storage of solar thermal energy through supercooled phase change materials (PCM) offers a promising solution for decarbonizing space and water heating in winter. Despite the high energy density and adaptability, natural PCMs often lack the neces

While a detonation engine’s burn rate is much faster than that of conventional turbine engines, its combustion chamber is also much smaller, resulting in higher pressure levels—and even more efficiency in extracting the energy. In the RDE combustion process, a detonation wave builds its own ...
The new method avoids problems inherent in ionization-based methods, such as those arising from differences in ionization potential or perturbations to the pressure that occur during electron ionization of the gas to be measured, and should be applicable in the trapping cells of FTICR and Orbitrap...
s−1is also imposed. Contiguous regions of grid cells with IVT values above the percentile threshold and fixed lower limit are isolated and labeled. An AR is considered to be a landfalling AR if a region of enhanced IVT intersects a grid cell occupied by the Antarctic Peninsula. The object...
