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 ...

Study on Seismic Safety Evaluation Models for Gravity Dams Based on Integrated Performance Indicators

Renmin Zhujiang
Existing studies typically explore the differences in seismic performance evaluation results of different evaluation models for concrete gravity dams by analyzing amplitude factors while neglecting the influence of ground motion duration.

Establishment of an MRI‐Based Diagnostic Approach to Identify Critical Pulpal Inflammation Zones in a Rat Caries‐Derived Pulpitis Model

International Endodontic Journal, EarlyView.
ABSTRACT Aim To establish a magnetic resonance imaging (MRI)‐based diagnostic approach for identifying ‘critical pulpal inflammation’ zones in a rat model of caries‐derived pulpitis. Methodology Caries‐derived pulpitis was induced in the molars of Sprague–Dawley rats using the caries‐derived pulpitis model.

Evaluating the Predictive Value of Estimated Breeding Values of Piétrain Sires for Uniformity and Survival in Their Crossbred Progeny

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT High litter sizes in pigs are associated with lower birth weights and increased within‐litter variation, which poses challenges to pig farming. Improving piglet uniformity and survival via genetic selection of terminal boars could be a strategy to enhance these traits.

Variable Sr Diffusion and Implications for Rb–Sr Biotite Geochronology

Journal of Metamorphic Geology, EarlyView.
ABSTRACT The rubidium–strontium (Rb–Sr) system has a long pedigree as a geochronological tool that relies on the application of an isochron approach. In particular, biotite contains strongly radiogenic Rb–Sr isotopes, and thus can yield meaningful crystallisation or cooling ages via this approach. However, the response of the Rb–Sr system in biotite to

Between Dispossession and Inclusion: Land Injustice and Project‐Based Citizenship in the Bagré Irrigation Scheme (Burkina Faso)

Journal of Agrarian Change, EarlyView.
ABSTRACT Large‐scale irrigation schemes are central to agrarian transformation in sub‐Saharan Africa, yet their political implications are often reduced to questions of land redistribution or agrarian differentiation. Although existing scholarship has documented how irrigation restructures agrarian relations and generates dispossession, less attention ...

Catastrophic Analysis of Seismic Response of Gravity Dam Sliding along Base Surface

, 2011
For the instability problem of gravity dam sliding along base surface, cubic nonlinear constitutive model of soft material in base surface is adopted, which is usually expressed by Weibull model.
