Tata Steel senior manager shot dead by ex-employee in Faridabad office

May 9: Union Home Minister Amit Shah has said the West Bengal government is not allowing trains with migrant workers to reach the state that may further create hardship for the labourers.

In a letter to West Bengal Chief Minister Mamata Banerjee, Shah said not allowing trains to reach West Bengal is "injustice" to the migrant workers from the state.

Referring to the 'Shramik Special' trains being run by the central government to facilitate transport of migrant workers from different parts of the country to various destinations, the home minister said in the letter that the Centre has facilitated more than two lakh migrants workers to reach home.

Shah said migrant workers from West Bengal are also eager to reach home and the central government is also facilitating the train services.

"But we are not getting expected support from the West Bengal. The state government of West Bengal is not allowing the trains reaching to West Bengal. This is injustice with West Bengal migrant labourers. This will create further hardship for them," Shah wrote.

Mumbai, Apr 29: Irrfan Khan, one of India's finest and most versatile actors, lost his battle with a rare form of cancer and died in a Mumbai hospital on Wednesday, a statement from his family said. He was 54

Irrfan, who was diagnosed with neuroendocrine tumour in 2018, is survived by his wife Sutapa and his sons Babil and Ayaan.

It is the second tragedy for the family in less than a week. The ?Maqbool? actor lost his mother, 95-year-old Saeeda Begum, in Jaipur just four days ago and could not attend the funeral because of the nationwide lockdown.

Irrfan, that rare actor who straddled multiple worlds, making his mark in both international and Indian cinema in roles intense and light-hearted, was admitted to the intensive care unit of the Kokilaben Dhirubhai Ambani Hospital with a colon infection

?It's saddening that this day, we have to bring forward the news of him passing away. Irrfan was a strong soul, someone who fought till the very end and always inspired everyone who came close to him. After having been struck by lightning in 2018 with the news of a rare cancer, he took life soon after as it came and he fought the many battles that came with it,? the statement from his family said

?Surrounded by his love, his family for whom he most cared about, he left for heavenly abode, leaving behind truly a legacy of his own. We all pray and hope that he is at peace. And to resonate and part with his words he had said, 'As if I was tasting life for the first time, the magical side of it',? it added.

The news of his death was first confirmed by his "Piku" director Shoojit Sircar who sent his condolences to the family and doffed his hat to the actor's fighting spirit

"My dear friend Irfaan. You fought and fought and fought. I will always be proud of you.. we shall meet again.. condolences to Sutapa and Babil.. you too fought, Sutapa you gave everything possible in this fight. Peace and Om shanti. Irfaan Khan salute," the director said on Twitter.

Irrfan's death came the morning after news that he had been admitted to the ICU with a colon infection.

The self-effacing National Award winner, who acted in films as diverse as ?Life of Pi?, ?The Namesake? and ?Haasil?, had stayed away from the public eye after his diagnosis in 2018 when he went to the UK for treatment.

He returned home in 2019 and shot for "Angrezi Medium", the sequel to his 2017 hit "Hindi Medium". However, his health condition prevented him from promoting the movie, which hit the theatres in March just before the lockdown that began on March 25.

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.
