Introduction: COVID-19 pandemic negatively influenced the entire life globally including various aspects of patients' care. Its effect on medical research production is not known. The aim of this study is to assess the impact of COVID-19 pandemic on medical research reporting trend. Methods: Advanced search on PubMed was performed over 2011- August, 2021. Monthly comparison was done for the years 2019, 2020, and 2021. Kruskal Wallis test was used to compare continuous distributions. Results: The total publication count showed constant increment over the study period. Faster rise was noticed on 2020 (15.7%). A steady growth in publications over the years and through the pandemic was also seen in seven studied countries with variable, both in total and also after exclusion of COVID-19 related papers. Italy and India have the highest proportions of COVID-19 related publications in comparison to the total papers in 2020, but USA has the highest quantity. Statistically significant differences exist between the first eight months of the last three years with and without counting COVID-19 related publications (p-values=0.0003907 and 0.001084, respectively). Conclusion: Our results reflect that investigators world-wide succeeded to reconfigure their work style and utilize the spared time induced by the lockdown to enrich the medical research platform.

Offshore wind is one of the most fascinating industries in the renewable energy sector and it is experiencing a remarkable growth. Offshore wind energy generation offers an opportunity in the race to decrease the dependence on fossil fuels, reduce green house emissions, increase energy security and create employment opportunities. UK has proven success in offshore wind and has been enjoying the economic benefits of offshore wind since over a decade. Offshore wind energy is an emergent renewable energy industry in the United States. The United States is coping up with the challenges and heading up fast to catch up with the industry. India is still in its infancy stage where the policy frameworks are framed by MNRE government and getting ready with the tools to enter into the offshore market. This paper researches the current situation and trend of offshore wind industries in UK and US, from aspects of policy, grid connections, operation and maintenance and cost reduction and analyses the proper direction and pathways of the industry to India. Therefore this paper highlights the scenario as to how these three countries UK, USA and India, respectively, are enabling offshore wind, to make a vital and sizeable contribution to the low carbon economy.

In this paper we use simulation to analyze how flight routing network structure may change in different world regions, and how this might impact future traffic growth and emissions. We compare models of the domestic Indian and US air transportation systems, representing developing and mature air transportation systems respectively. We explicitly model passenger and airline decision-making, capturing passenger demand effects and airline operational responses, including airline network change. The models are applied to simulate air transportation system growth for networks of 49 airports in each country from 2005 to 2050. In India, the percentage of connecting passengers simulated decreases significantly (from over 40% in 2005 to under 10% in 2050), indicating that a shift in network structure towards increased point-to-point routing can be expected. In contrast, very little network change is simulated for the US airport set modeled. The simulated impact of network change on system CO 2 emissions is very small, although in the case of India it could enable a large increase in demand, and therefore a significant reduction in emissions per passenger (by nearly 25%). NO x emissions at major hub airports are also estimated, and could initially reduce relative to a case in which network change is not simulated (by nearly 25% in the case of Mumbai in 2025). This effect, however, is significantly reduced by 2050 because of frequency competition effects. We conclude that network effects are important when estimating CO 2 emissions per passenger and local air quality effects at hub airports in developing air transportation systems.
