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, May 30: The Congress on Friday described the first year of the Modi government as a "year of disappointment, disastrous management and diabolical pain".

Congress leader K C Venugopal said the six years of the Modi dispensation have seen fraying of bonds of empathy, fraternity and brotherhood with increase in acts of communal and sectarian violence.

Congress chief spokesperson Randeep Surjewala said that at the end of six years, it appears the Modi government is at war with its people and is inflicting wounds on them, instead of healing them.

"It is inflicting wounds on Mother India," he said.

"This government is trying to fill coffers of the select rich and is inflicting pain on the poor," Surjewala said.

On the BJP's charge of the Congress playing politics over the COVID-19 crisis, Venugopal said the opposition party did not indulge in any politics and gave suggestions instead.

"Being a responsible opposition, it is our duty to raise the problems faced by the common people. As opposition, we highlighted the failures of the government," he said.

Venugopal said the government "is totally insensitive" to the plight of migrant labourers and farmers.

Surjewala also demanded that a virtual session of Parliament be convened immediately to discuss pressing issues and the due process be set in motion for holding of meetings of various parliamentary committees.

Modi and his cabinet had taken oath on this day last year for a second term in office.

Ayodhya, Jul 23: All 32 accused in the Babri mosque demolition case should be invited to the "bhumi pujan" ceremony for the construction of the Ram temple here and honoured, a Hindutva outfit leader has said.

Hindu Dharma Sena president Santosh Dubey is one of the main accused in the case.

Dubey also insisted that the Shri Ram Janmabhoomi Teertha Kshetra Trust must also invite all the four Shankaracharyas to the ceremony planned on August 5.

Prime Minister Narendra Modi is also likely to attend the event.

"The office bearers of Ram Janmabhoomi Teerth Kshetra must ensure that along with all 32 accused in the Babri mosque demolition case, the families of the kar sevaks who gave their lives in the Ram Temple movement must also be invited to the 'bhumi pujan' ceremony and must be honoured there," Dubey told PTI.

The top court verdict in favour of the Ram temple at the site would not have been possible had the Babri mosque not been demolished, he said.

"If the Trust does not invite the kar sevaks, it will a display of ego and arrogance. Without inviting the kar sevaks who have been accused in Babri mosque demolition and the families of the slain kar sevaks, the 'bhumi pujan' will remain incomplete," Dubey added.

A special CBI court in Lucknow is recording the statements of the 32 Babri demolition accused under section 313 of the CrPC, which enables them to plead their innocence, if they so want.

The court is conducting day-to-day hearings to complete the trial by August 31 as directed by the Supreme Court.

The mosque in Ayodhya was demolished on December 6, 1992 by 'kar sevaks' who claimed that an ancient Ram temple had stood on the same site. Former deputy prime minister L K Advani and BJP leader Murli Manohar Joshi were leading the Ram temple movement at that time.
