Cerebral and Peripheral Hemodynamics Across Wakefulness and NREM Sleep
Journal of Sleep Research, EarlyView.ABSTRACT Wake/sleep‐related changes in cerebral hemodynamic oscillations are well established, but similar changes in peripheral hemodynamics remain largely understudied. Moreover, how the relationship between cerebral and peripheral hemodynamics varies across sleep–wake states is not well understood, despite evidence that these oscillations in the low‐

FORMATION CONDITIONS OF AGATES [PDF]
Минералогия, 2017 Agates are formed at various temperatures, which covers a wide range from those of basaltic and andesitic melts (above 1100 °С) to several tens of centigrade, but at rather low pressures. Their formation in liquid mafic magmas is indicated by correlation
