RESUMO
Energy is a key component for economic growth as well as for human development. India is the third-ranking electricity generator in the world but ranks 106th in terms of per capita consumption. Specifically, the distribution of power is the most important link in the value chain of the power sector since it is the cash register for the entire sector. In India, electricity is a concurrent subject shared between the Central and State Governments. While the generation of power has been deregulated since 2003, the supply of power to the consumers is generally carried out by Government-owned power Distribution Companies (DISCOMs). In this paper, the authors analyze the financial distress of DISCOMs in India, and explain how the supply-demand mismatch due to over-ambitious demand projections, the fixed and energy charges of thermal power plants, and the excess procurement of "must-run" renewable sources together contribute to the high cost of power procurement that drives the financial stress faced by DISCOMs. The authors support their assertion with a study of nine DISCOMs supplying electricity to 155 million people in three States and propose policy recommendations for a turnaround of such DISCOMs which can be rolled out with suitable modifications across India.
RESUMO
The COVID-19 pandemic elicited a global response to limit associated mortality, with social distancing and lockdowns being imposed. In India, human activities were restricted from late March 2020. This 'anthropogenic emissions switch-off' presented an opportunity to investigate impacts of COVID-19 mitigation measures on ambient air quality in five Indian cities (Chennai, Delhi, Hyderabad, Kolkata, and Mumbai), using in-situ measurements from 2015 to 2020. For each year, we isolated, analysed and compared fine particulate matter (PM2.5) concentration data from 25 March to 11 May, to elucidate the effects of the lockdown. Like other global cities, we observed substantial reductions in PM2.5 concentrations, from 19 to 43% (Chennai), 41-53% (Delhi), 26-54% (Hyderabad), 24-36% (Kolkata), and 10-39% (Mumbai). Generally, cities with larger traffic volumes showed greater reductions. Aerosol loading decreased by 29% (Chennai), 11% (Delhi), 4% (Kolkata), and 1% (Mumbai) against 2019 data. Health and related economic impact assessments indicated 630 prevented premature deaths during lockdown across all five cities, valued at 0.69 billion USD. Improvements in air quality may be considered a temporary lockdown benefit as revitalising the economy could reverse this trend. Regulatory bodies must closely monitor air quality levels, which currently offer a baseline for future mitigation plans.
RESUMO
BACKGROUND: The selection of a low-risk blood donor involves a dialogue between the trained medical staff and the volunteer blood donor, and this is where the knowledge of the prospective blood donor with regard to the risk factors for acquiring hepatitis B and C and the mode of spread through a blood transfusion is of utmost importance. Therefore, the study was conducted to assess the knowledge and attitude on hepatitis B and C with regard to blood donation, in the existing and the potential donor base. MATERIALS AND METHODS: This is a cross-sectional study conducted on 4000 participants, including 2000 blood donors and 2000 nondonors. The study tool was a pilot-tested, self-administered questionnaire, content and construct validated using Delphi methodology. RESULTS: The mean age of the study participants was 25.12 ± 8.43 years ranging from 18 to 60 years; 24.64 ± 8.31 years in donors and 25.61 ± 8.55 years in non-donors. The study included 69.8% males and 30.2% females, with 87.5% males and 12.6% females in donors and 52.1% males and 47.9% females in non-donors. Overall knowledge score was 51.02%, being 51.21% in donors and 50.84% in non-donors. Overall attitude score was 47.93%, being 47.09% in donors and 48.77% in non-donors. There was a low degree of significant linear correlation between knowledge and attitude in the study participants. CONCLUSION: Based on the results obtained in the study, it is evident that neither the existing level of knowledge nor the attitude of both donors and nondonors towards hepatitis B and C is adequate for being able to select a low-risk blood donor.
