Hindu Mahasabha hosts ‘cow urine drinking party’ to cure COVID-19

New Delhi, Apr 23: Delhi Police has booked Jamia students Meeran Haider and Safoora Zargar under the Unlawful Activities (Prevention) Act (UAPA) in a case related to communal violence in northeast Delhi over the Citizenship (Amendment) Act, said a lawyer.

Haider and Zargar, arrested for allegedly hatching a conspiracy to incite the communal riots in February, are in judicial custody. While Zargar is the media coordinator of Jamia Coordination Committee, Haider is a member of the committee.

The police has also booked Jawaharlal Nehru University student leader Umar Khalid under the UAPA in the case, said advocate Akram Khan who is representing Haider in the case.

Haider (35) is a PhD student and the president of RJD youth wing's Delhi unit, while Zargar is an MPhil student of Jamia Millia Islamia (JMI) university.

In the FIR, the police has claimed that the communal violence was a "premeditated conspiracy" which was allegedly hatched by Khalid and two others.

The students have also been booked for the offences of sedition, murder, attempt to murder, promoting enmity between different groups on grounds of religion and rioting.

Khalid had allegedly given provocative speeches at two different places and appealed to the citizens to come out on streets and block the roads during the visit of US President Donald Trump to spread propaganda at international level about how minorities in India are being , the FIR alleged.

In this conspiracy, firearms, petrol bombs, acid bottles and stones were collected at numerous homes, the FIR claimed.

Co-accused Danish was given the responsibility to gather people from two different places to take part in the riots, the police alleged.

Women and children were made to block the roads under the Jafrabad metro station on February 23 to create tension amidst the neighbourhood people, it said.

Over 20 film personalities, including Anurag Kashyap, Vishal Bhardwaj, Mahesh Bhatt and Ratna Pathak Shah, on Sunday had released a statement raising their voice against the arrest of the students and activists by Delhi Police for protesting against the Citizenship (Amendment) Act and demanded their release.

Following this, the police had said investigations into the JMI violence and northeast Delhi riot cases were done impartially, and arrests were made after analysis of forensic evidence.

In December last year, the police had allegedly entered the JMI campus after protests over the CAA, being held a few metres away from the varsity, turned violent.

Rajya Sabha MP and RJD leader Manoj Jha had tweeted, "Delhi Police called him for investigation and then received orders from above and arrested Meeran Haider, who has been helping people during the time of coronavirus outbreak."

The Jamia Coordination Committee (JCC), a group comprising students and alumni from the varsity, had condemned the arrest and demanded his immediate release.

"The country is facing a massive health crisis, however, the state machinery is busy harassing and framing student activists in false cases to suppress voices of dissent," they said.

The JCC said Haider was diligently working to provide ration to the needy during the lockdown. Communal clashes had broken out in northeast Delhi on February 24 after violence between citizenship law supporters and protesters spiralled out of control leaving at least 53 people dead and around 200 injured.

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 5: Joining efforts to fight COVID-19, the Defence Research and Development Organisation (DRDO) has designed a full-body disinfection chamber and a special face protection mask for healthcare professionals, officials said.

The special chamber called 'PSE' has been designed by Vehicle Research Development Establishment (VRDE), Ahmednagar, a DRDO Laboratory.

The walk through enclosure is designed for personnel decontamination, one person at a time. It is a portable system equipped with sanitiser and soap dispenser, officials said.

The decontamination is started using a foot pedal at the entry. On entering the chamber, electrically-operated pump creates a disinfectant mist of hypo sodium chloride for disinfecting, the DRDO said in a statement.

The mist spray is calibrated for an operation of 25 seconds and stops automatically indicating completion of operation. As per procedure, personnel undergoing disinfection will need to keep their eyes closed while inside the chamber, it said.

The system consists of roof mounted and bottom tanks with a total of 700 litres capacity. Approximately 650 personnel can pass through the chamber for disinfection until the refill is required, the DRDO said.

The system has see-through glass panels on side walls for monitoring purpose and is fitted with lights for illumination during night-time operations, it added.

This system can be used for disinfection of personnel at the areas of controlled ingress and egress such as entry and exit to hospitals, malls, office buildings and critical installations, officials said.

Also, Research Centre Imarat (RCI), Hyderabad, and Terminal Ballistics Research Laboratory (TBRL), Chandigarh, have developed face protection mask for healthcare professionals handling COVID-19 patients, the DRDO added.

Its light weight construction makes it convenient for comfortable wear for long duration. This design uses commonly available A4 size Over-Head Projection (OHP) film for face protection, it said.

One thousand face shields are being produced daily in TBRL and provided to Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, it said.

Similarly, 100 are produced at RCI and these have been handed over to Employees' State Insurance Corporation (ESIC), Hyderabad. A demand of 10,000 shields has been received from PGIMER and ESIC hospitals based on successful user trials, the DRDO added.
