Ashok Chavan charge sheeted in Adarsh scam

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.

Lucknow, May 27: Uttar Pradesh chief minister Yogi Adityanath has taken a U-turn, two days after he declared that permission would be needed if other states employ workers from UP.

The issue sparked a major controversy and an official spokesman has now said that the government would not include this clause of 'prior permission' in the bye-laws of the Migration Commission.

The government spokesman also said it was working on modalities to set up the commission to provide jobs and social security to migrant workers returning to the state. It has named the migration commission as the "Shramik Kalyan Aayog (Workers welfare commission).

About 26 lakh migrants have already returned to the state and an exercise to map their skills is being carried out to help them get jobs.

Yogi Adityanath has discussed the modalities for setting up the commission and told his officers to complete the skill mapping exercise in 15 days.

A senior official of Team 11, said, "The chief minister discussed the modalities for setting up the commission, as well. There will be no provision requiring other states to seek UP government's prior permission for employing our manpower. The commission is being set up to provide jobs and social security to the workers. We will also link the migrants to the government schemes to provide them houses and loans etc."

Yogi Adityanath said a letter should be sent to all state governments to find out about migrant workers wanting to come back to Uttar Pradesh.

Earlier, the chief minister, while speaking at a webinar on Sunday, had said, "The migration commission will work in the interest of migrant workers. If any other state wants UP's manpower, they cannot take them just like that, but will have to seek permission of the UP government. The way our migrant workers were ill-treated in other states, the UP government will take their insurance, social security in its hands now. The state government will stand by them wherever they work, whether in Uttar Pradesh, other states or other countries."

The statement had sparked a row with some political leaders and parties questioning the move.

Former Congress president Rahul Gandhi sharply criticized Adityanath's stand, saying the workers were not the chief minister's personal property.

"It is very unfortunate that the chief minister of Uttar Pradesh views India in such a way. These people are not his personal property. They are not the personal property of Uttar Pradesh. These people are Indian citizens and they have the right to decide what they want to do and they have the right to live the life they want to live," he had said.

Maharashtra Navnirman Sena chief Raj Thackeray had also taken on Adityanath and said that if UP insists on "permission" before other states can employ workers from there, "then any migrant entering Maharashtra would need to take permissions from us, from the Maharashtra state, our police force too."

Meanwhile, the government spokesman said, "The chief minister is deeply moved by the condition of migrants. They have been treated badly by other states. So, when the chief minister spoke about the need for seeking UP government's permission, he did so as a guardian for workers. It's only his concern for the migrants that came out as a political statement."

Jan 17: India's "high power" communication satellite GSAT-30 was successfully launched in the early hours of January 17, the Indian Space Research Organisation (ISRO) said.

The satellite, aimed at providing high-quality television, telecommunications and broadcasting services, was launched onboard Ariane 5 rocket from French Guiana.

Blasting off from the Ariane Launch Complex in Kourou, a French territory located in northeastern coast of South America at 2.35 am IST, European space consortium Arianespace's Ariane 5 vehicle injected GSAT-30 into the orbit in a flawless flight lasting about 38 minutes.

Arianespace CEO Stéphane Israël tweeted about the successful launch of GSAT-30.

ISRO's U R Rao Satellite Centre Director P Kunhikrishnan, who was present in Kourou, congratulated the ISRO community and Arianespace team on the successful launch.

Calling it an "excellent start" to 2020 for ISRO with the launch, he said, "The mission team at the master control facility have already acquired the satellite and they will immediately complete the post launch operations...."

The 3,357-kg satellite, which was deployed from the lower passenger position of Ariane-5 launch vehicle (VA 251) into to geostationary transfer orbit (GTO), is configured on ISRO's enhanced I-3K Bus structure to provide communication services from Geostationary orbit in C and Ku bands.

The satellite derives its heritage from ISRO's earlier INSAT/GSAT satellite series, and is equipped with 12 C and 12 Ku band transponders.

GSAT-30 is to serve as replacement to the "aging" INSAT-4A spacecraft services with enhanced coverage, ISRO has said, adding the satellite provides Indian mainland and islands coverage in Ku-band and extended coverage in C-band covering Gulf countries, a large number of Asian countries and Australia.

With a mission life of 15 years, GSAT-30 is an operational communication satellite for DTH, television uplink and VSAT services.

The Bengaluru-headquartered ISRO has said the communication payload of GSAT-30 is specifically designed and optimised to maximise the number of transponders on the spacecraft bus.

According to the space agency, the spacecraft would be extensively used for supporting VSAT (Very Small Aperture Terminal) network, television uplinking and teleport services, digital satellite news gathering (DSNG), DTH television services, cellular backhaul connectivity and many such applications.

One Ku-band beacon downlink signal is transmitted for ground-tracking purpose, it added.

For its initial flight of 2020, Arianespace on its website said, it would orbit EUTELSAT KONNECT, a telecommunication satellite for the operator Eutelsat, along with GSAT-30, using an Ariane 5 launch vehicle from the Guiana Space Centre.

EUTELSAT KONNECT – which was produced by Thales Alenia Space for Eutelsat – was riding in the upper position of Ariane 5's payload arrangement, and was released first in the flight sequence at 27 minutes following liftoff.

Since the launch of India's APPLE experimental satellite on Ariane Flight L03 in 1981, Arianespace has orbited 24 satellites, including GSAT-30, for the Indian space agency.
