Don't warn us: Rajnath Singh tells China

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.

New Delhi, Jun 20: A rare celestial event, annular solar eclipse, which is popularly known as the "ring of fire" eclipse, will be visible this Sunday in India.

It will be the first solar eclipse of this year takes place on the summer solstice, which is the longest day in the Northern Hemisphere.

While people living along the path annular eclipse passing through Anupgarh, Suratgarh, Sirsa, Jakhal, Kurukshetra, Yamunanagar, Dehradun, Tapowan and Joshimath will be able to see the annular phase, people in rest of India can witness a partial eclipse, said the Ministry of Science and Technology.

When Moon comes between the Sun and Earth, the shadow falls on the surface of the Earth. The Sun is entirely covered by the Moon for a brief period. Those places that are engulfed by the dark, dense umbral shadow of the Moon experience the total solar eclipse. In the regions that plunge into the soft diffused penumbral shadow of the Moon experience the partial eclipse.

"Annular solar eclipse is a particular case of the total solar eclipse. Like the total solar eclipse, the Moon is aligned with the Sun. However, on that day, the apparent size of the Moon happens to be a wee smaller than the Sun. Hence the Moon covers the central part of the Sun, and the rim of the Sun appear like a 'ring of fire' in the sky for a very brief moment" explains Samir Dhurde of The Inter-University Centre for Astronomy and Astrophysics, Pune.

During the solar eclipse, the apparent size of the Moon is smaller than that of the Sun by 1 per cent, the expert said.

Allying rumours that the eclipse will mark the end of coronavirus, Aniket Sule, Chairperson, Public Outreach and Education Committee of the Astronomical Society of India, said: "Solar eclipse is caused when the Moon comes in front of the Sun for a short time. As seen from Earth eclipses occur somewhere in the Earth 2 to 5 times a year. Eclipses do not impact microorganisms on Earth. Likewise there no danger in eating of stepping out during an eclipse. No mysterious rays come out of the Sun during an eclipse."

New Delhi, May 15: Microsoft founder Bill Gates on Friday thanked Prime Minister Narendra Modi for the interaction and stressed that combating the coronavirus pandemic requires global collaboration.

"Thank you for the conversation and partnership PM Narendra Modi. Combating the pandemic requires global collaboration. India's role is key as the world works to minimize social and economic impact, and pave the way to vaccine, testing, and treatment access for all," Bill Gates said.

Prime Minister Narendra Modi on Thursday interacted with philanthropist and Microsoft co-founder Bill Gates and discussed the global response to Covid-19 and the importance of global coordination on scientific innovation to combat the pandemic.

The Prime Minister underlined the conscious approach that India has adopted in its fight against the health crisis - an approach based on ensuring public engagement through appropriate messaging, a PMO release said.

He explained how this people-centric bottom-up approach has helped win acceptability for physical distancing, respect for frontline workers, wearing of masks, maintaining proper hygiene, and respecting lockdown provisions.

They agreed that given India's willingness and capacity to contribute to global efforts, particularly for benefit of fellow developing countries, it was important for India to be included in the ongoing global discussions for coordinating responses to the pandemic.

The Prime Minister also suggested that the Gates Foundation could take the lead in analyzing the necessary changes in lifestyles, economic organisation, social behaviour, modes of disseminating education and healthcare, that would emerge in the post-Covid world, and the associated technological challenges that would need to be addressed.

He said that India would be happy to contribute to such an analytical exercise based on its own experiences.
