The Digital Earth as Knowledge Engine Editorial
The Digital Earth [13] aims at developing a digital representation of the planet. It is motivated by the need for integrating and interlinking vast geo-referenced, multi-thematic, and multi-perspective knowledge archives that cut through domain boundaries. Complex scientific questions cannot be answered from within one domain alone but span over multiple scientific disciplines. For instance, st...
متن کاملEarth ’ s surface heat flux
We present a revised estimate of Earth’s surface heat flux that is based upon a heat flow data-set with 38 347 measurements, which is 55% more than used in previous estimates. Our methodology, like others, accounts for hydrothermal circulation in young oceanic crust by utilising a half-space cooling approximation. For the rest of Earth’s surface, we estimate the average heat flow for different ...
متن کاملMudball: Surface dust and Snowball Earth deglaciation
[1] Recent modeling results have raised doubts about the ability to deglaciate from a global glaciation at atmospheric carbon dioxide levels that are realistic for a Neoproterozoic Snowball Earth. Here we argue that over the lifetime of a Snowball event, ice dynamics should lead to the development of a layer of continental and volcanic dust at the ice surface in the tropics that would significa...
متن کاملEditorial: Archaeal Cell Envelope and Surface Structures
Archaea and Bacteria have complex cell envelopes that play important roles in several vital cellular processes, including serving as a barrier that protects the cytoplasm from the environment. Along with associated proteinaceous structures, cell envelopes also ensure cell stability, promote motility, mediate adherence to biotic and abiotic surfaces, and facilitate communication with the extrace...
متن کاملSurface EMG application in clinical biomechanics. Editorial.
‘‘The course of a movement is nothing else but a projection to the outside of a pattern of excitation taking place in a corresponding setting in the central nervous system‘‘. This citation of Hess (1954, according to Waterland, 1968) has caught my attention since the first day of my studies of the neuro-musculo-skeletal system in kinesiological tasks. Pursuing a bioengineering approach and inve...
