Bengaluru, Feb 22: Student activist Amulya Leona, who was arrested on sedition charge after she raised ‘Pakistan Zindabad’ slogans during an anti-CAA event at Bengaluru’s Freedom Park on Thursday evening, has now criticised the organisers of the event for snatching away microphone from her hand.

The event was organised by ‘Hindu Muslim Sikh Isaai Federation’. Soon after she started pro-Pak slogans All India Majlis-e-Ittehadul Muslimeen (AIMIM) chief Asaduddin Owaisi rushed and tried to snatch mic from her hand. When she continued to speak, her microphone was deactivated.

According to police, the 19-year-old BA journalism student blamed her predicament on the organisers of the protest for not allowing her to complete what she wanted to say on stage.

"Maybe she had intended to say what she had recently posted on her Facebook page where she has said ‘Zindabad’ to all the countries, including India and Pakistan. But it went awry. She was not answering any of our questions, but kept saying she had not done anything wrong," a senior police officer was quoted as saying by a news paper.

The police have booked Leona for sedition and promoting enmity between groups. After her arrest, she was thoroughly questioned by the police for over two hours. After recording her statement, the police produced her before a magistrate in the wee hours of Friday. When she was taken to the judge’s residence, located at the National Games Village in Koramangala, Leona pointed towards the TV cameras and flashed a victory sign.

As the police did not seek her custody, the judge remanded her to judicial custody and she was subsequently taken to Bengaluru Central Prison at Parappana Agrahara. Her advocate is expected to file a bail application in the court on Monday.

When the police took her into custody at Freedom Park and quizzed her, she reportedly did not answer any of their questions but kept insisting that she had not done anything anti-national to be charged with sedition.

"It was the organisers’ mistake to snatch the mike from me before I completed what I had to say. Because of them, I have been arrested today. If they had given me a chance to complete what I had to say, nothing like this would have happened. Now, there is no point in telling you what I intended to speak there. But I can say that there was nothing anti-national in what I did. You can initiate action against me and my advocate will fight the case," a source, citing Leona, said.

The police recorded whatever she said as her voluntary statement and submitted it to the magistrate. "We tried to find out why she did what she did and whether there was anyone else behind her making such a statement. But it appears she had done it on her own," the police official said.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.
