The climate of the Holocene is not well suited to be the baseline for the climate of the planet. It is an interglacial, a state typical of only 10% of the past few million years. It is a time of relative sea-level stability after a rapid 130-m rise from the lowstand during the last glacial maximum. Physical geologic processes are operating at unusual rates and much of the geochemical system is ...

A category of new photochromatic storage material has been found suitable for rewritable digital video disc (DVD). The ratio of transmissivity before and after the write-in process is 3:1 at X = 450 n m (blue) and 1:7 at X = 650 nm (Ed), with a transition time of 2-3 ns. The number of write-erase cycles is about 1,000. MO aor PC can have the same advantage. However, since there are some specid ...

Цель исследования – оценить эффективность, безопасность и травматичность эндоскопической дискэктомии в сравнении с традиционной микрохирургической дискэктомией. Материал и методы. Выполнено 330 эндоскопических дискэктомий по методике Дестандо и 964 открытых микрохирургических дискэктомии. Сравнивали длительность операции, продолжительность послеоперационного постельного режима и пребывания паци...

Valentine and Moores [Valentine JW, Moores EM (1970) Nature 228:657-659] hypothesized that plate tectonics regulates global biodiversity by changing the geographic arrangement of continental crust, but the data required to fully test the hypothesis were not available. Here, we use a global database of marine animal fossil occurrences and a paleogeographic reconstruction model to test the hypoth...

The southern Indian Ocean has several prominent aseismic ridges recognized as oceanic large igneous provinces (i.e., the Madagascar Ridge, Del Cano Rise, Crozet Plateau, and Conrad Rise) in off-axis areas of Southwest Ridge (SWIR). However, previously obtained magnetic survey lines are sparse not correctly aligned with seafloor spreading direction; thus, detailed history, including formation th...

The most spectacular example of a plate convergence event on Earth is the motion of the Indian plate towards Eurasia at speeds in excess of 18 cmyr−1 (ref. 1), and the subsequent collision. Continental buoyancy usually stalls subduction shortly after collision, as is seen in most sections of the Alpine–Himalayan chain. However, in the Indian section of this chain, plate velocities were merely r...

The main aim of this article is to analyze a recent text by Nenad Miščević dealing with social epistemology in the context of Foucault's theory of knowledge. In the first part, we briefly note Miščević's thoughts on the difference between analytic and continental philosophy and his thoughts on the latter. In the second part, we analyze both Miščević’s thesis about Foucault's dual understanding ...

[1] A new reanalysis of the global ocean circulation is used to distinguish between the steric and eustatic components of sea level rise. Recent altimeter observations indicate an increase in the rate of sea level rise during the past decade to 3.2 mm/yr, well above the centennial estimate of 1.5–2 mm/yr. This apparent increase could have resulted from enhanced melting of continental ice or fro...
