Poet Imran Pratapgarhi booked for 'provocative' remarks on Shaheen Bagh in Hyderabad

Lucknow, Mar 3: Two days after wife of Kafeel Khan, who is booked under the National Security Act, alleged that her husband faced a threat to life in Mathura jail, where he is lodged for anti-CAA protests, the District Magistrate claimed that Khan was 'fully secure' in the jail.

"Kafeel Khan, who has been booked under the National Security Act (NSA) for alleged inflammatory statements during an anti-CAA protest in Aligarh, is absolutely fine and fully secure in Mathura jail. Allegations of 'inhuman' treatment being meted out to him are baseless," Mathura District Magistrate Sarvagya Ram Mishra said on Monday.

Senior Superintendent of Mathura district prison, Shailendra Maitrey, said that Khan's condition is being monitored every half an hour and the report is written in the gate book. He said, his ECG is normal and blood pressure was also in control.

He said that Khan was demanding checkup from a cardiologist.

"Since no specialist is available in the government sector here, his request could not be complied with. However, the jail authorities have sent his request to chief medical officer and have asked him to make a specialist available," the jail official said.

He said Khan is in barrack, which is fully ventilated, and he shares it with 50-60 'good behaviour' prisoners.

It may be recalled that in a letter to the Chief Justice of Allahabad High Court, Additional Chief Secretary (Home), and Director General (Jail), Shabista Khan, wife of the jailed doctor, had alleged that her husband was being treated inhumanely in the jail.

She feared that an attempt could be made on her husband's life inside the jail. She had demanded adequate security for him and had urged that her husband should be kept away from active criminals lodged in the jail.

Khan was booked by Aligarh police on December 13 for delivering a provocative speech in Aligarh Muslim University (AMU) during an anti-CAA protest in the campus, a day earlier, and was arrested from Mumbai airport on January 29 by Uttar Pradesh special task force.

The Aligarh police had slapped the stringent National Security Act (NSA) against Khan on February 13 night, hours before he was expected to walk free from the Mathura jail, after he was granted bail by Aligarh's chief judicial magistrate on February 10.

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.
