Indira Gandhi was a power crazy woman, why should we honour people like her and Rajiv: Katju on stamps row

New Delhi, May 25: Mahindra Group Chairman Anand Mahindra on Monday said lockdown extensions are not just economically disastrous but also create another medical crisis.

While acknowledging that choices are not easy for policymakers, he said a lockdown extension will not help.

"Lockdown extensions aren't just economically disastrous, as I had tweeted earlier, but also create another medical crisis," Mahindra said in a tweet.

He was referring to an article that highlighted "the dangerous psychological effects of lockdowns & the huge risk of neglecting non-COVID patients".

Mahindra, who had earlier proposed a comprehensive lifting after 49 days of lockdown, further said, "The choices aren't easy for policy makers but a lockdown extension won't help".

He said, "The numbers (coronavirus cases) will continue to rise & the focus must be on rapid expansion of field hospital beds with oxygen lines".

He further said, "The army has enormous expertise in this".

On March 22, before the government announced nationwide lockdown, Mahindra had proposed such a move expressing concerns over reports that India was likely to have already reached stage 3 of coronavirus transmission.

Kolkata, May 20: Cyclone 'Amphan' lay centred about 240 km south of Digha in West Bengal on Wednesday morning as an extremely severe cyclonic storm, the Met department said here.

The intensity near the centre of the storm was 170 to 180 kmph gusting to 200 kmph, the Met said.

'Amphan' is very likely to move north-northeastwards and cross West Bengal-Bangladesh coast between Digha and Hatiya, close to the Sunderbans during the afternoon to evening of Wednesday with a wind speed of 155 to 165 kmph gusting to 185 kmph as a 'very severe cyclonic storm', the Met department said.

West Bengal has evacuated more than three lakh people to safer places as the cyclonic storm 'Amphan' roared towards the coastal areas of the state, officials said.

The Met department, which has issued an "orange message" for West Bengal, warned of extensive damage in Kolkata, Hooghly, Howrah, South and North 24 Parganas and East Midnapore districts.

The Met department has advised that all establishments and markets remain closed in Kolkata and adjoining areas and movement of people be restricted on May 20.

There is likely to be disruption of rail and road link at several places, uprooting of communication and power poles, extensive damage to all types of 'kutcha' houses and some damage to "old badly managed pucca" structures and potential threat from flying objects, the weatherman warned.

There is also likelihood of extensive damage to standing crops, plantations and orchards and blowing down of palm and coconut trees, the Met said.

The weatherman has advised diversion or suspension of rail and road traffic in the districts which are likely to be affected.

The Eastern Railway (ER) has cancelled the departure of Howrah-New Delhi AC Special Express for Wednesday.

The departure of 02301 Howrah-New Delhi AC Special Express on Wednesday and 02302 New Delhi-Howrah AC Special Express on May 21 would remain cancelled, the ER said.

Wind speed along and off the coastal areas of West Bengal will reach 75 to 85 kmph with gusts up to 95 kmph from Wednesday morning along and off districts of North and South 24 Parganas, East and West Midnapore, Kolkata, Howrah and Hooghly, Regional Met director G K Das said.

"It will gradually increase thereafter becoming 110 to 120 kmph gusting to 130 kmph over West Midnapore, Howrah, Hooghly, Kolkata and wind speed of 155 to 165 kmph gusting to 185 kmph over the districts of North and South 24 Parganas and East Midnapore of West Bengal from the afternoon to night of May 20," he said.

Under its impact rainfall will occur in most places over the districts of Gangetic West Bengal on Wednesday, with heavy to very heavy downpour with extremely heavy rain at a few places in Kolkata, Howrah, East Midnapore, North and South 24 Parganas and Hooghly districts, he said.

"Storm surge of 4 to 5 metres above astronomical tide is likely to inundate low lying areas of South and North 24 Parganas and about 3 to 4 metres over low lying areas of East Midnapore district of West Bengal during the time of landfall," he said.

The Indian Navy has dispatched a diving team for providing assistance to the West Bengal government in relief operations, a Defence official said.

The diving team from Vishakhapatnam has brought specialised equipment along with them which can be used for rescue in case of flooding and have been positioned at the Naval Service Selection Board at Diamond Harbour in South 24 Parganas district, the official 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.
