Cash-for-vote scam: Andhra CM Naidu lands in trouble over purported phone conversation

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, Apr 21: The historic rout in oil markets that sent US crude prices plummeting to as much as minus USD 40 a barrel is unlikely to translate into any big reduction in petrol and diesel prices in India as domestic pricing is based on different benchmark, and refineries are already filled up to brim and cannot buy US crude just yet.

With storage capacity already overflowing amid coronavirus-induced demand collapse, traders rushed to to get rid of unwanted stocks triggering the collapse of US West Texas Intermediate (WTI) crude for May delivery.

Indian Oil Corp (IOC) Chairman Sanjiv Singh said the collapse was triggered by traders unable to take deliveries of crude they had previously booked because of a demand collapse. And so they paid the seller to keep oil in their storage.

"If you look at June futures, it is trading in positive territory... around USD 20 per barrel," he said.

Low oil prices may seem good in short-term but in the long run it will hurt the oil economy as producers will have no surplus to invest in exploration and production which will lead to a drop in production, he said.

He did not comment on retail fuel prices that have been static since March 16.

Oil companies have not changed rates despite a fall in international prices as they first adjusted them against the increase that was warranted from a Rs 3 per litre hike in excise duty and close to Re 1 per litre additional cost of switching over to cleaner BS-VI grade fuel from April 1.

Petrol in Delhi is priced at Rs 69.59 a litre and diesel comes for Rs 62.29 per litre.

"The negative price has no direct impact on India or Indian oil prices, as this has taken place due to crude oil produced and traded within the US. India's prices are driven partly by another benchmark, the Brent, which is still trading at USD 25/barrel. Therefore, the retail price of fuels in India are unlikely to fall," said Amit Bhandari, Fellow, Energy and Environment Studies, Gateway House.

Also, Indian refineries are already overflowing as fuel demand has evaporated due to the unprecedented nationwide lockdown imposed to curb spread of COVID-19. So, they can't rush to buy US crude.

The refineries have already cut operating rate to half because the fuel they produce has not been sold yet.

India imports 4 million barrels/day (1.4 billion barrels/year) of oil. The country has been benefitting from the falling prices of oil for the last five years, when oil dropped from a peak of USD 110/barrel to USD 50-60/barrel last year, enabling India to invest in public service programmes.

"However, the additional USD 30 fall of this week is good for India - but there is also a downside. If oil prices are too low, the economies of oil-rich gulf countries will be hurt, threatening the job prospects of the 8 million Indians working in the Gulf countries. India is the largest recipient of foreign remittances due to these workers – very low oil prices will hurt this cash stream," Bhandari said.

He said the negative price of oil shows how much oil oversupply exists in international markets today. "Global oil consumption has fallen due to the COVID-19 pandemic that traders are willing to pay customers to get rid of the barrels they can't store. The world does not have enough storage capacity, and dumping the oil is an environmental crime."

The first half of April saw Brent crude oil prices plummet 63.6 per cent to USD 26.9 per barrel. Prices of Western Texas Intermediate (WTI), the American oil, had also fallen similarly by 63.1 per cent.

But on April 20, WTI prices turned rapidly negative because traders on the Nymex exchange rushed to offload their May futures positions a day before expiry of contracts (on April 21).

Such WTI futures are traded on the Nymex exchange with contracts settled in physical crude oil. Problem is, those who had gone long are unable to find storage facilities for the oil and had to liquidate their contracts before expiry. This caused the plunge in WTI prices.

Contrast to this, June WTI Nymex futures prices is hovering around USD 21, while Brent for June delivery is at USD 25.

Miren Lodha, Director, CRISIL Research said the demand for crude oil was declining already because of economic slowdown when the COVID-19 pandemic-driven lockdowns crushed it further.

Consequently, oil demand is expected to contract by 8-10 million barrels per day (mbpd) in 2020 assuming demand recovery begins from the third quarter of the year, he said, adding if recovery doesn't happen by then, further demand destruction could occur.

On the supply side, producers reining in output following a strategic deal between OPEC members, Russia and the US.

Under this agreement, OPEC+ would reduce oil production by 9.7 mbpd for May and June, but gradually ease the curb to 7.7 mbpd between July and December 2020, and to 5.8 mbpd till April 2022 to stabilise prices.

"This is expected to reduce some surplus in the market by the end of 2020," Lodha said.

Crude oil demand is expected to decline by over 20 mbpd in April alone. Typically, monthly global demand is about 100 mbpd. Given this scenario, supply curbs would have limited influence.

Consequently, Brent oil prices is expected to be in the USD 25-30 range for the second quarter while increasing marginally in the last 2 quarters of 2020.

"The gigantic inventory build-ups and lack of storage facilities would also put pressure on prices," he said, adding overall Brent could average USD 30-35 in 2020, with a strong downward bias.
