Ambassador of France to confer 'Knight of the Legion of Honour' to Azim Premji

Paris, Jul 2: Several interacting exoplanets have already been spotted by satellites. But a new breakthrough has been achieved with, for the first time, the detection directly from the ground of an extrasolar system of this type.

An international collaboration including CNRS researchers has discovered an unusual planetary system, dubbed WASP-148, using the French instrument SOPHIE at the Observatoire de Haute-Provence (CNRS/Aix-Marseille Universite).

The scientists analysed the star's motion and concluded that it hosted two planets, WASP-148b and WASP-148c. The observations showed that the two planets were strongly interacting, which was confirmed from other data.

Whereas the first planet, WASP-148b, orbits its star in nearly nine days, the second one, WASP-148c, takes four times longer. This ratio between the orbital periods implies that the WASP-148 system is close to resonance, meaning that there is enhanced gravitational interaction between the two planets. And it turns out that the astronomers did indeed detect variations in the orbital periods of the planets.

While a single planet, uninfluenced by a second one, would move with a constant period, WASP-148b and WASP-148c undergo acceleration and deceleration that provides evidence of their interaction.

The study will shortly be published in the journal Astronomy & Astrophysics.

In the wake of the gas leak at a factory in Visakhapatnam, the National Disaster Management Authority (NDMA) has issued detailed guidelines for restarting industries after the lockdown and the precautions to be taken for the safety of the plants as well as the workers.

In a communication to all states and union territories, the NDMA said due to several weeks of lockdown and the closure of industrial units, it is possible that some of the operators might not have followed the established standard operating procedures.

As a result, some of the manufacturing facilities, pipelines, valves may have residual chemicals, which may pose risk. The same is true for the storage facilities with hazardous chemicals and flammable materials, it said.

The NDMA guidelines said while restarting a unit, the first week should be considered as the trial or test run period after ensuring all safety protocols.

Companies should not try to achieve high production targets. There should be 24-hour sanitisation of the factory premises, it said.

The factories need to maintain a sanitisation routine every two-three hours especially in the common areas that include lunch rooms and common tables which will have to be wiped clean with disinfectants after every single use, it added.

For accommodation, the NDMA said, sanitisation needs to be performed regularly to ensure worker safety and reduce the spread of contamination.

To minimise the risk, it is important that employees who work on specific equipment are sensitised and made aware of the need to identify abnormalities like strange sounds or smell, exposed wires, vibrations, leaks, smoke, abnormal wobbling, irregular grinding or other potentially hazardous signs which indicate the need for immediate maintenance or if required shutdown, it said.

At least 11 people lost their lives and about 1,000 others were exposed to a gas leak at a factory in Andhra Pradesh''s Visakhapatnam on May 7.

The incident took place after it restarted operations when the government allowed industrial activities in certain sectors following several weeks of lockdown.

The lockdown was first announced by Prime Minister Narendra Modi on March 24 for 21 days in a bid to combat the coronavirus threat. The lockdown was then extended till May 3 and again till May 17.

Due to impacts of COVID-19, shipments of total mobile phones are forecast to decline 14.6% in 2020, while smartphone shipments will achieve a slightly slower decline of 13.7 % year over year to total 1.3 billion units this year, according to a Gartner forecast on Tuesday.

"While users have increased the use of their mobile phones to communicate with colleagues, work partners, friends and families during lockdowns, reduced disposable income will result in fewer consumers upgrading their phones," Ranjit Atwal, Senior Research Director at Gartner, said in a statement.

"As a result, phone lifetimes will extend from 2.5 years in 2018 to 2.7 years in 2020," said Atwal.

In 2020, affordable 5G phones were expected to be the catalyst to increase phone replacements, but now it is unlikely to be the case.

5G phones are now forecast to represent only 11% of total mobile phone shipments in 2020.

"The delayed delivery of some 5G flagship phones is an ongoing issue," said Annette Zimmermann, Research Vice President at Gartner.

"Moreover, the lack of 5G geographical coverage along with the increasing cost of the 5G phone contract will impact the choice of a 5G phone."

Overall, spending on 5G phones will be impacted in most regions apart from China, where continued investment in 5G infrastructure is expected, allowing providers in China to effectively market 5G phones.

The combined global shipments PCs, tablets and mobile phones are on pace to decline 13.6% in 2020, according to the forecast.

PC shipments are expected to decline 10.5% this year. Shipments of notebooks, tablets and Chromebooks are forecast to decline slower than the PC market overall in 2020.

"The forecasted decline in the PC market in particular could have been much worse," said Atwal.

"However, government lockdowns due to COVID-19 forced businesses and schools to enable millions of people to work from home and increase spending on new notebooks, Chromebooks and tablets for those workers. Education and government establishments also increased spending on those devices to facilitate e-learning."

Gartner said that 48 per cent of employees will likely work remotely at least part of the time after the COVID-19 pandemic, compared to 30 % pre-pandemic.

Overall, the work from home trend will make IT departments shift to more notebooks, tablets and Chrome devices for work.

"This trend combined with businesses required to create flexible business continuity plans will make business notebooks displace desk based PCs through 2021 and 2022," said Atwal.
