Impact on solar radiation parameters in India during COVID-19 lockdown: a case study

International Journal of Sustainable Energy, 2021
The current research objective is to explore changes in solar radiation variables across the Indian region during the lock-down period. Global Horizontal Irradiance (GHI), Direct Normal Irradiance (DNI) and Diffuse Horizontal Irradiance (DHI) were ...

South-hemispheric marine aerosol Hg and S isotope compositions reveal different oxidation pathways

National Science Open, 2022
Particle-bound mercury (PBM) records the oxidation of elemental mercury, of which the main oxidation pathways (Br∙/Cl∙/OH∙/O3) remain unclear, especially in the Southern Hemisphere. Here, we present latitudinal covariations of Hg and S-isotopic anomalies

Non-Classical Effects of the cAMP Accumulation Activators In Vivo [PDF]

Advanced Pharmaceutical Bulletin, 2020
Purpose: Wound-healing dipyridamole- and papaverine-based aerosols (D1/D2) as activators of the accumulation of cyclic adenosine monophosphate are promising drugs that can accelerate wound healing in wound processes of various origins.

The influence of temperature, humidity, and simulated sunlight on the infectivity of SARS-CoV-2 in aerosols

Aerosol Science and Technology, 2020
Recent evidence suggests that respiratory aerosols may play a role in the spread of SARS-CoV-2 during the ongoing COVID-19 pandemic. Our laboratory has previously demonstrated that simulated sunlight inactivated SARS-CoV-2 in aerosols and on surfaces. In

Cloud fraction estimation using random forest classifier on sky images [PDF]

Atmospheric Measurement Techniques
Cloud fraction (CF) is an integral aspect of weather and radiation forecasting, but real time monitoring of CF is still inaccurate, expensive and exclusive to commercial sky imagers. Traditional cloud segmentation methods, which often rely on empirically

Critical assessment of the current state of scientific knowledge, terminology, and research needs concerning the role of organic aerosols in the atmosphere, climate, and global change

, 2005
In spite of impressive advances in recent years, our present understanding of organic aerosol (OA) composition, physical and chemical properties, sources and transformation characteristics is still rather limited, and their environmental effects remain ...
