[1] We explore the mechanisms whereby groundwater influences terrestrial water storage (TWS) in the Amazon using GRACE observations and two contrasting versions of the LEAF-Hydro-Flood hydrological model: one with and the other without an interactive groundwater. We find that, first, where the water table is shallow as in northwestern Amazonia and floodplains elsewhere, subsurface stores (vados...

The activity of the sodium-potassium (Na+-K+) pump in arterial tissue from rats with chronic DOCA-salt or one-kidney Grollman renal hypertension was assayed in vitro as the rate of ouabain-sensitive 86Rb+ uptake. Estimates of total cell Na+ and tissue K+ were made by a lithium-substitution method on the same segment of arterial tissue. In both freshly excised tail arteries and aortas, and in ao...

The shares of RE sources are rising because global warming concerns and the depletion fossil fuels. However, due to its intermittent nature sustainable power supply depends on proper energy mix storage. By 2025, Ethiopia has planned export 24 TWh energy. Accordingly, generation is incorporating different dominated by hydropower. This paper reviewed up-to-date status PHES Ethiopia’s current situ...

The laws of fluid mechanics imply that modular offshore pumped hydro-energy storage systems like StEnSEA have no advantage over similar but much cheaper onshore systems.

Many countries have targeted a gradual transition towards 100% green generation; however, there is uncertainty concerning the economic and social consequences of such transition. The main technologies that been implemented are hydro, wind solar. latter two could cause an increase in electricity prices due to mismatch between demand supply. This paper uses system dynamics approach analyze proces...
