Nations within a nation: variations in epidemiological transition across the states of India, 1990–2016 in the Global Burden of Disease Study
18% of the world's population lives in India, and many states of India have populations similar to those of large countries. Action to effectively improve population health in India requires availability of reliable and comprehensive state-level estimates of disease burden and risk factors over time. Such comprehensive estimates have not been available so far for all major diseases and risk factors. Thus, we aimed to estimate the disease burden and risk factors in every state of India as part of the Global Burden of Disease (GBD) Study 2016
Reflectance and magneto-optical Kerr rotation in DyP
66-68The rare-earth compounds are distinguished by their unique magnetic, electric and optical properties. These are strongly correlated materials. Their highly localized 4f electrons are responsible for their large magnetic moment. Optical properties of a material can be utilized in different applications such as reflectors, filters, and X-ray masks. On the other hand, magneto-optical properties of materials are used in storage devices. The calculations of optical properties of rare-earth compound DyP using the full potential linear augmented plane wave (FPLAPW) method with inclusion of spin orbit coupling have been reported. The Coulomb-corrected local spin density approximation, i.e. LSDA+U, which is known to treat the highly correlated 4f electrons properly have been employed. The calculated optical properties are in good agreement with the measured value. The magneto-optical Kerr rotation has been reported and the values expected for DyP in the low energy range have been predicted
Optical properties of CeSb and LaSb
69-71The calculations of the electronic and the optical properties of CeSb and LaSb, using the full potential augmented plane wave (FP-LAPW) method including spin orbit coupling within local spin density (LSDA) approximation as implemented in WIEN2K code have been performed. The reflectivity and the real part of the optical conductivity of CeSb and LaSb have been calculated. The real part of the optical conductivity of these compounds is deduced from Kramers-Kronig transformation. The calculated spectra of the real part of the optical conductivity and reflectivity of LaSb and CeSb are in the agreement with the available experimental data. Our calculations give the value of specific heat constant of CeSb and LaSb 23.4 mJmol⁻¹K⁻² and 0.37 mJmol⁻¹K⁻², respectively, which are very close to experimental value
