Polling begins for Lok Sabha, Assembly seats in Telangana

Kolkata, Jun 24: Trinamool Congress (TMC) MLA Tamonash Ghosh, who had tested positive for Covid-19 in May, died at a hospital here on Wednesday, party sources said.

He was 60.

The three-time MLA from the Falta assembly constituency in South 24 Parganas district was admitted to a hospital after he tested positive for the disease, they said.

He had several complications related to the heart and the kidney, the sources said.

"Very, very sad. Tamonash Ghosh, 3-time MLA from Falta & party treasurer since 1998 had to leave us today. Been with us for over 35 years, he was dedicated to the cause of the people & party. He contributed much through his social work," West Bengal Chief Minister and TMC supremo Mamata Banerjee tweeted.

"He has left a void that will be difficult to fill. On behalf of all of us, heartfelt condolences to his wife Jharna, his two daughters, friends and well-wishers," she added.

Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.

Aurangabad, Apr 4: A marriage was solemnised on a video call, the unique method which was adopted due to coronavirus lockdown.

A Muslim man named Mohammad Minhajudd, based in Aurangabad exchanged marriage vows with a Muslim woman based in Beed via video call on Friday.

The entire country is witnessing a 21-day lockdown due to which there is a limitation on the movement of people from one place to another and gatherings have been banned to prevent the spread of the coronavirus that has wreaked havoc across the globe.

The marriage halls are also closed during the lockdown period.

The bridegroom's father Mohammad Gayaz said that the marriage was fixed between the two persons six months ago when there was no fear about coronavirus. We got the elders of the family assembled at our home and conducted the marriage on phone.

Mufti Anis ur Rehman, the Qazi who performed the rituals for the marriage, said that both the families are happy as the marriage got conducted with the minimal cost incurred and the ceremony was a simple one.
