Green Developmentalism? The Political Economy of Hydropower in India in the 21st Century
Development and Change, EarlyView.ABSTRACT This article critically examines the political economy of hydropower in India since its global reconfiguration as ‘green energy’ in the early 2000s. While an opportune convergence of interests among key global, national and subnational stakeholders contributed to the greening of hydropower in India, this reframing did not produce the expected ...

Journal of Product Innovation Management, EarlyView.ABSTRACT Academic Summary Despite the urgent need for a circular economy, firms' transition from linear to circular business models (CBMs) remains slow. While previous research suggests that dynamic capabilities are the key drivers of this transition, it assumes a direct link, overlooking that these capabilities can facilitate change but do not ...

Experimental Physiology, EarlyView.Abstract This study investigated cerebral and neuromuscular responses to three exercise models: time trial (TT), maximal oxygen uptake (V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{max}}}}$) and time to exhaustion (TTE). Fourteen participants completed the tests in the following order: V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{max}}}}$, TT and ...

Numerical Investigations on the Transient Performance of a Centrifugal Pump
Centrifugal pumps are an integral part of plants used in process industries. The flow structure within a centrifugal pump is very complex due to the interaction between the rotating impeller and the geometric features around it.

Pump as Turbine - Symmetry Prediction Method for Pump as Turbine Characteristics
, 2018 As a cheap and available source of renewable energy, regular centrifugal pumps may be run in reverse to act as hydro turbines. Pumps as turbines (PAT) are especially relevant for isolated rural areas, or in developing countries, where efficiency is not necessarily the highest priority.
