Rahul Gandhi will take over as Congress President soon, confirms Sonia

Mumbai, Apr 4: As many as six Central Industrial Security Force (CISF) personnel stationed at Mumbai airport in Maharashtra have tested positive for coronavirus, taking the total number of positive cases among the central force to 11. The first case of a CISF jawan being diagnosed with the viral disease was reported on March 28. 

After the first case, the armed police force reported four more cases of COVID-19 among the personnel stationed at the airport on Thursday. On the same day, the CISF collected samples of 146 staff and sent them to Kasturba hospital for testing. The results, which arrived on Friday, recorded six more COVID-19 cases among, reported news agency.

The personnel were posted at Kharghar adjoining Mumbai, a senior official told news agency.

As of now, there are 14 COVID-19 cases in Panvel Municipal Corporation (PMC) area in Mumbai. Kharghar comes under the civic body's jurisdiction.

All the 146 CISF personnel were shifted to a quarantine centre at a facility at Kamothe reported the Times of India.

Maharashtra reported 67 new COVID-19 cases, taking the total tally to 490. A total of 26 deaths have been reported in the state.  

In the meantime, the Centre on Friday said there is no shortage of medical supplies across the country to fight COVID-19 outbreak.

"The government of India is making sure that all the essential medical supplies are in place to fight COVID-19. Sixty-two lifeline Udan flights transported over 15.4 tons of essential medical supplies in the last five days," Union Minister for Chemical and Fertilisers DV Sadanada Gowda said in a tweet.

The government is also paying full attention to the manufacturing activities of essential items like pharmaceuticals and hospital devices. For this, over 200 units in Special Economic Zones (SEZs)  are operational, he added.

"A Central Control Room has also been set up for close monitoring of the distribution of essential medical items and to address logistic related issues," Gowda said.

New Delhi, Jan 5: A masked mob on Sunday entered the Sabarmati Hostel on the Jawaharlal Nehru University (JNU) campus and assaulted several students and professors with sticks and rods.

"I have been brutally attacked by goons wearing masks. I am bleeding. I was brutally beaten up," JNU Students' Union (JNUSU) president Aishe Ghosh told reporters.

She has been admitted to the AIIMS here for treatment.

Several other students were also injured in the incident.

In a video of the incident, a group of goons with their faces covered can be seen assaulting students with wooden sticks and rods.

A tweet from the official handle of the JNUSU said, "Sabarmati Hostel: right now. They are beating the students who are inside. Knocking on doors with rods. People are jumping from balconies. #SOSJNU #EmergencyinJNU."

"Professors who were trying to protect us have been beaten up. These are unknown ABVP goons, not all are students, they have covered their faces, and they are moving towards the hotels near the West Gate. Stay alert. Make human chains. Protect each other. #SOSJNU #EmergencyinJNU," another tweet added.

Meanwhile, the ABVP's JNU unit claimed in a tweet: "Emergency in JNU. Leftist goons of JNU accompained with their cadre from other universities have crossed every limit. They have proceeded with unimaginable violence on ABVP activists of JNU."

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.
