World's tallest statue of Lord Ram to be built in Ayodhya

Wayanad, Jan 30: Congress leader Rahul Gandhi on Thursday compared Mahatma Gandhi assassin Nathuram Godse with Prime Minister Narendra Modi, saying both believed in the same ideology.

Gandhi, at an anti-CAA rally here, launched a scathing attack on Modi and said he was making Indians to prove that they are Indians.

Addressing participants at "Save the Constitution" march at Kalpetta in Wayanad, his Lok Sabha constituency on Martyr's Day, Gandhi said there was no difference between Godse and Modi.

"Today, an ignorant man is trying to challenge Gandhi's ideology. He is creating an atmosphere of hatred. The ideology is same. Nathuram Godse and Narendra Modi, they believe in the same ideology. There is no difference except that Modi does not have the guts to say he believes in the ideology of Godse," the Wayanad MP said.

Attacking the Prime Minister on the new Citizenship Law, Gandhi questioned Modi and asked who was he to ask Indians to prove that they were Indians.

"Indians are being made to prove that they are Indians. Who is Narendra Modi to decide who is an Indian. Who gave Modi the licence to ask for my Indianness? I know I am an Indian and I don't have to prove it to anyone. Likewise, 1.4 billion Indians do not have to prove that they are Indians," he said.

The Congress leader led the march here as part of efforts to intensify the party's protests against CAA in the state.

New Delhi, July 13: The number of active Covid-19 cases in India crossed the 3 lakh mark on Sunday even as fresh infections during the day surged to another new peak, crossing 29,000 for the first time. After staying over 500 for the past two days, the daily death toll came down slightly to 492.

While the focus has been on recoveries, the number of active Covid-19 cases in the country has been steadily rising. It hit the 1 lakh mark on June 4 and went past 2 lakh 23 days later. It has taken just 15 days more to reach 3 lakh.

India reported 29,271 new cases on Sunday, the fifth straight day of record rise in daily infections. With this, the country’s coronavirus caseload has risen to 8,79,060, two days after hitting the 8 lakh mark, as per data collated from state governments. Active cases stood at 3,02,466 while more than 5.53 lakh people were declared cured of the infection.

Covid-19 deaths in the country rose to 23,175 after 492 fatalities were added on Sunday, translating to a case fatality rate of 2.6%. The CFR has been steadily dropping with the surge in cases.
 

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.
