‘Modi’s Kedarnath show after campaign is poll code violation’: TMC complains to EC

Jan 29: Multiple organisations have called for a Bharat Bandh today in order to protest against the recently passed Citizenship Amendment Act and the proposed National Register of Citizens (NRC). The Bharat  Bandh today has been organised in Surat in Gujarat, Jharkhand and Andhra Pradesh. Increased security measures have been put in place in the three states keeping in view the call for shutdown.

According to media reports, the call for Bharat Bandh was given by Maulana Sajjad Nomani of the All India Muslim Personal Law Board (AIMPLB). This was to protest against the controversial CAA-NRC. This call is supported by an NGO based in Surat, Versatile Minorities Forum (VMF). Apart from the VMF, the call for strikes has been supported by organizations such as Bahujan Kranti Morcha, National Association of Street Vendors of India Surat chapter and the Textile Market Workers' Union.

The workers of the VMF were also spotted distributing pamphlets and urging people to support the strike. Several shopkeepers have also put up notices stating that their shops will be shut for the day.

Earlier, Bharat Bandh was called by 10 trade unions and several bank employees in order to protest against the "anti-people policies of the government" on January 8 and 9. A few violent incidents during this Bharat Bandh were reported in West Bengal.

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, Apr 23: With an increase of 1,229 new COVID-19 cases in the last 24 hours, the total number of cases reached 21,700, said the Union Ministry of Health and Family Welfare on Thursday.

The tally is inclusive of 16,689 active cases, 4,325 patients have been cured/discharged and migrated, while 686 patients who have died due to the deadly virus.

According to the ministry's data, Maharashtra is on the top of the list with most COVID-19 cases, 5,652 cases of which 789 patients have recovered and 269 patients succumbing to coronavirus.

Gujarat and Delhi are second and third on the list respectively with Gujarat having 2407 cases of which 179 patients have recovered and 103 deaths. Meanwhile, in Delhi, the tally stands at 2248 cases of which 724 patients have recovered and 49 patients have died from COVID-19.

Rajasthan's tally stands at 1,890 cases with 230 patients cured while 27 deaths have been reported as of Thursday.

Madhya Pradesh has 1695 cases of which 148 patients have recovered and 81 deaths reported. Tamil Nadu, on the other hand, stands with 1629 cases of which 662 patients have recovered and 18 have died due to the deadly virus.

Goa has seven cases reported of which all seven patients have recovered from the coronavirus.

Prime Minister Narendra Modi announced on April 14, that the nationwide lockdown would be extended to May 3.
