Water plays an important role in geological processes. Providing constraints on what may influence the distribution of aqueous fluids is thus crucial to understanding how water impacts Earth's geodynamics. Here we demonstrate that ductile flow exerts a dynamic control on water-rich fluid circulation in mantle shear zones. Based on amphibole distribution and using dislocation slip-systems as a p...

We examine the possible extent of melting in rock-iron super-earths, focusing on those in the habitable zone. We consider the energetics of accretion and core formation, the timescale of cooling and its dependence on viscosity and partial melting, thermal regulation via the temperature dependence of viscosity, and the melting curves of rock and iron components at the ultra-high pressures charac...

The Yellowstone supervolcano is one of the largest active continental silicic volcanic fields in the world. An understanding of its properties is key to enhancing our knowledge of volcanic mechanisms and corresponding risk. Using a joint local and teleseismic earthquake P-wave seismic inversion, we revealed a basaltic lower-crustal magma body that provides a magmatic link between the Yellowston...

We studied life history responses of larvae of three coccinellid species, Coleomegilla maculata (DeGeer), Hippodamia convergens Guerin-Meneville, and Harmonia axyridis (Pallas), when deprived of food for different periods of time during the fourth stadium. The coccinellid species did not differ in starvation resistance when larvae were starved throughout the stadium; however, for larvae fed onl...

Medicines of plant origin containing polysaccharides are used in pharmaceutical practice since they exhibit a wide spectrum thepharmacological activity. Species the Alchemilla L. genus Rosaceae family important scientific and practical importance; contain different groups biologically active substances (BAS), including phenolic compounds polysaccharides. The lack information literature on quant...

The object of this study is to determine the best solvent and optimum extraction conditions for maximum phenolic compounds from Alchemilla vulgaris leaves. Extractions were carried out using solvents with different polarities. Box-Behnken Design was used optimize including time, temperature, liquid/solid ratio. In study, extract obtained acetone-water indicated highest total content (TPC), flav...
