'Suit boot' is more acceptable than 'suitcase': Modi

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 12: Petrol price on Friday was hiked by 57 paise per litre and diesel by 59 paise a litre as oil companies adjusted retail rates - the sixth straight day of increase in rates since oil firms ended an 82-day hiatus of rate revision.

Petrol price in Delhi was hiked to Rs 74.57 per litre from Rs 74, while diesel rates were increased to Rs 72.81 a litre from Rs 72.22, according to a price notification of state oil marketing companies.

Rates have been increased across the country and vary in each state depending on the incidence of local sales tax or value added tax.

This is the sixth consecutive daily increase in rates since oil companies on Sunday restarted revising prices in line with costs, after ending an 82-day hiatus.

In six hikes, petrol price has gone up by Rs 3.31 per litre and diesel by Rs 3.42.

Ahmedabad, Jul 23: Private schools in Gujarat have suspended online classes for an indefinite period from Thursday, after a state government order said they should not collect fees from students until the schools reopen.

In a notification issued last week, the Gujarat government directed self-financed schools in the state not to collect tuition fees from students as long as they remain shut in the wake of the COVID-19 pandemic.

It also asked these schools not to hike fees for the academic year 2020-21.

Unhappy with the move, a union of representing nearly 15,000 self-financed schools in Gujarat decided to put on hold online classes, an alternative arrangement started earlier this month for students.

Majority of these schools informed the parents through SMS on Wednesday night that there will not be any online classes for their wards from Thursday.

Self-financed School Management Association's spokesperson Dipak Rajyaguru on Thursday said almost all the self-financed schools in the state refrained from imparting online education.

"If the government believes online education is not real education, then there is no meaning of imparting such unreal education to our students. Online education will remain suspended until the government withdraws that notification," Rajyaguru said in a statement.

He said the association will also approach the high court against state government's decision.

Jatin Bharad, a prominent educationist and member of the association, said there is no alternative to online education in the present scenario.

"Self-financed schools need to pay salaries to the teachers and other staff. No state in India has taken such decision that fees cannot be collected despite conducting online classes. If we adhere to the state notification, it will be impossible for us to pay salaries and run the school.

Thus, we have decided to suspend the online classes," said Bharad said.
