Electricity is critical to enabling India’s economic growth and providing a better future for its citizens. In spite of several decades of reform, the Indian electricity sector is unable to provide high-quality and affordable electricity for all, and grapples with the challenge of poor financial and operational performance. To understand why, Mapping Power provides the most comprehensive analysis of the political economy of electricity in India’s states. With chapters on fifteen states by scholars of state politics and electricity, this volume maps the political and economic forces that constrain and shape decisions in electricity distribute on. Contrary to conventional wisdom, it concludes that attempts to depoliticize the sector are misplaced and could worsen outcomes. Instead, it suggests that a historically grounded political economy analysis helps understand the past and devise reforms to simultaneously improve sectoral outcomes and generate political rewards. These arguments have implications for the challenges facing India’s electricity future, including providing electricity to all, implementing government reform schemes, and successfully managing the rise of renewable energy.

AbstractWe report on the abundances of helium, carbon, nitrogen and oxygen in a larger sample of Galactic massive stars of ~7-20 M⊙ near the main sequence, composed of apparently normal objects, pulsators of β-Cephei- and SPB-type, and magnetic stars. High-quality spectra are homogeneously analysed using sophisticated non-LTE line-formation and comprehensive analysis strategies. All the stars follow a previously established tight trend in the N/C-N/O ratio and show normal helium abundances, tracing the nuclear path of the CNO-cycles quantitatively. A correlation of the strength of the mixing signature with the presence of magnetic fields is found. In conjunction with low rotation velocities this implies that magnetic breaking is highly efficient for the spin-down of some massive stars. We suggest several objects for follow-up spectropolarimetry, as the mixing signature indicates a possible magnetic nature of these stars.

As Nb films are widely used as superconducting electrodes of Josephson junctions, it is important to investigate the properties of Nb films in order to fabricate high-quality Josephson junctions. In this work, we conducted a comprehensive analysis of the relationships among the properties of DC magnetron sputtered Nb films with a constant power fabricated at the National Institute of Metrology (China). The film properties, including superconductivity, stress, lattice constant, and surface roughness, were investigated. It was found that in the case of constant power and Ar pressure, the stress and other parameters of the Nb films can maintain a relatively stable state during the continuous consumption of the target material.
