Video of BJP minister peeing on roadside goes viral

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.

New Delhi, Feb 23: Hailing the role of first Prime Minister Jawaharlal Nehru in shaping India a modern nation state, former Prime Minister Manmohan Singh on Saturday hit out at the Narendra Modi-led Central government, saying "nationalism" and the slogan of 'Bharat Mata Ki Jai' are being misused to construct a militant and purely emotional idea of India.

Speaking at the launch of a book on Jawaharlal Nehru's works and speeches, Singh said: "I am extremely happy that this book makes an effort to revisit Pandit Nehru. He had led this country in its volatile, formative days when we adopted democratic way of life, accommodating divergent social and political views."

The former Prime Minister said that Nehru, who was very proud of Indian heritage, "assimilated it", and harmonised them into the needs of a "new modern" India.

"A great visionary, Nehruji laid the foundation for shaping India as a modern nation state," he said.

Highlighting the works of the first Prime Minister, Singh said: "If India is recognized in the comity of nations as a vibrant democracy and, if it is considered as one of the important world powers, it was Nehru, who should be recognised as its main architect."

He said Nehru was not only a statesman of high international standing, but a great historian and literary figure too.

"With an inimitable style, and a multi-linguist, Nehru laid the foundation of the universities, academies and cultural institutions of Modern India. But for Nehru's leadership, Independent India would not have become what it is today," he said.

Taking an apparent dig at the BJP government, he said: "But unfortunately, a section of people who either do not have the patience to read history or would like to be deliberately guided by their prejudices, try their best to picture Nehru in a false light.

"But I am sure, history has a capacity to reject fake and false insinuations and put everything in proper perspective," he said.

He said the book "Who is Bharat Mata" is such an attempt to set the narrative in the right direction.

Singh said that selecting appropriate pieces from Nehruji's works, the book justifies its title "Who is Bharat Mata?"

"As this book contains a timely collection of writings by and on Pandit Jawaharlal Nehru- the leader, who shaped India and the Icon whose legacy is the subject of intense and often angry reaction today.

The book also comprises reminiscences and assessments of Nehru by some of his contemporaries and near contemporaries-among them, including Mahatma Gandhi, Bhagat Singh, Sardar Patel, Maulana Azad, Aruna Asaf Ali, Sheikh Abdullah, Ramdhari Singh Dinkar, Ali Sardar Jafri, Baldev Singh, Martin Luther King Jr, Richard Attenborough, Lee Kuan Yew and Atal Bihari Vajpayee.

"It is a book of particular relevance at a time when nationalism and the slogan of ‘Bharat Mata Ki Jai' are being misused to construct a militant and purely emotional idea of India that excludes millions of residents and citizens," Singh said attacking the BJP government.

The two time Prime Minister further said that in the pages of the carefully complied anthology-which also carries illuminating introductions by the authors Nehru emerges as a "remarkable man of ideas and action", who had an instinctive understanding of India's civilisational spirit and as a visionary with clear commitment to the promotion of scientific temper, who despite the compulsions of politics, remained a true democrat.

"His legacy continues to be of immense significance-perhaps more today than at any other time in our history," he said.

He also warned that "Nehru makes a very significant and time relevant remark on the dangers of leaderships falling into a trap and getting removed far away from the common people whom they are supposed to serve".

"In an atmosphere, when emotions are deliberately get provoked and the gullible are misled by false propaganda, misusing communication technology, this book makes a refreshing break through," Singh added.

Aligarh, Feb 11: Paediatrician Dr Kafeel Khan, who was arrested from Mumbai on January 29 after he delivered a speech at Aligarh Muslim University (AMU) against communalism and politics of hate, will be released from jail on Tuesday after he was granted bail by an Aligarh court.

Khan will be released from Mathura jail on Tuesday after legal formalities are completed.

Chief judicial magistrate Karuna Singh granted bail to Khan on Monday on a bail bond of Rs 60,000. Two surety bonds of Rs 60,000 each would also be furnished by the guarantors.

Dr Khan's lawyer, Mohammad Irfan Gazi, told reporters, "The court was told that Khan was falsely implicated by police under political pressure. After hearing the arguments, the court granted him bail."

The suspended doctor was arrested by special task force (STF) of the UP police from Mumbai on January 29, when he reached the city to attend a protest against the Citizenship (Amendment) Act.

He was arrested in connection with a case registered against him in Aligarh under section 153-A (promoting enmity between different groups on ground of religion) of the Indian Penal Code at Civil Lines police station on December 13

The case was filed after his speech at Aligarh Muslim University (AMU).

According to the FIR, while addressing students, without naming anyone, Dr Kafeel Khan said that 'Mota Bhai' is teaching everyone to become Hindu or Muslim but not a human being. "This is a fight for our existence. We have to fight."

The FIR also said that Dr Kafeel Khan made an attempt to vitiate the peaceful atmosphere and disturb the communal harmony with his speech.

Dr Khan was in the news in 2017 when he was named as one of the nine accused in a case involving deaths of several children due to alleged disruption in supply of oxygen at the BRD Medical College in Gorakhpur. Though he was granted clean chit in a departmental inquiry, his suspension has not yet been revoked.
