I-T raids premises of Cafe Coffee Day owner V G Siddhartha

Udupi, Jan 19: Union Minister for Finance and Corporate Affairs Nirmala Sitaraman has said the mutt tradition in Udupi is a unique tradition and a perfect example of the country’s rich heritage of spirituality.

Speaking at the Darbar organised for the incoming Paryaya Admar Mutt seer Sri Eeshapriya Theertha Swamiji at Rajangana, here Saturday night, she said, “Paryaya festival is not just an event. It represents the presence of the Lord. I am conscious about the history. I am immensely blessed to be associated with the Krishna Mutt in one or the other.”

She turned nostalgic and traced her connection with the Krishna mutt which started in her childhood. “I am attached to the Mutt and temple due to my maternal uncle. My uncle was a bank employee and he spent his career in Manipal. I am being drawn to the mutt for the past 25 years. I am blessed immensely by the seers of the mutt and Lord Krishna.”

New Delhi, Jun 16: Jet fuel or ATF price on Tuesday was hiked by 16.3 per cent while petrol price was increased by 47 paise per litre and that of diesel by a record 93 paise on the back of firming international oil rates.

Aviation turbine fuel (ATF) price was hiked by ₹5,494.5 per kilolitre (kl), or 16.3 per cent, to ₹39,069.87 per kl in the national capital, according to a price notification by state-owned oil marketing companies.

This is the second straight increase in ATF price this month. Rates were hiked by a record 56.5 per cent (₹12,126.75 per kl) on June 1.

Simultaneously, petrol and diesel prices were hiked for the 10th day in a row.

Petrol price in Delhi was hiked to ₹76.73 per litre from ₹76.26, while diesel rates were increased to ₹75.19 a litre from ₹74.26, the price notification said.

In 10 hikes, petrol price has gone up by ₹5.47 per litre and diesel by Rs 5.8 a litre.

Rates have been increased across the country and vary from state to state depending on the incidence of local sales tax or VAT.

The hike in diesel rates is the highest daily increase since the state-owned fuel retailers started daily revision in rates in May 2017.

Hike for 10th consecutive day

Tuesday’s increase in petrol and diesel price marks the 10th straight day of rise in rates since oil companies on June 7 restarted revising prices in line with costs, after ending an 82-day hiatus.

The freeze in rates was imposed in mid-March soon after the government hiked excise duty on petrol and diesel to shore up additional finances.

Oil PSUs Indian Oil Corp (IOC), Bharat Petroleum Corp Ltd (BPCL) and Hindustan Petroleum Corp Ltd (HPCL) instead of passing on the excise duty hikes to customers adjusted them against the fall in the retail rates that was warranted because of fall in international oil prices.

The June 1 hike in jet fuel price had come after seven consecutive reductions in rates since February. ATF price in Delhi before the reduction cycle began in February was ₹64,323.76 per kilolitre, which got reduced to ₹21,448.62 last month.

Industry officials said the hike was necessitated because benchmark international rates have bounced back from a two-decade low.

While ATF prices are revised on 1st and 16th of every month, petrol and diesel prices are revised on a daily basis.

Oil companies used to revise ATF prices on the first of every month, but adopted fortnightly revisions on March 21 to pass on the benefit of falling international oil prices to airlines.

The coronavirus can stay aloft for hours in tiny droplets in stagnant air, infecting people as they inhale, mounting scientific evidence suggests.

This risk is highest in crowded indoor spaces with poor ventilation, and may help explain superspreading events reported in meatpacking plants, churches and restaurants.

It’s unclear how often the virus is spread via these tiny droplets, or aerosols, compared with larger droplets that are expelled when a sick person coughs or sneezes, or transmitted through contact with contaminated surfaces, said Linsey Marr, an aerosol expert at Virginia Tech.

Aerosols are released even when a person without symptoms exhales, talks or sings, according to Marr and more than 200 other experts, who have outlined the evidence in an open letter to the World Health Organization.

What is clear, they said, is that people should consider minimizing time indoors with people outside their families. Schools, nursing homes and businesses should consider adding powerful new air filters and ultraviolet lights that can kill airborne viruses.

What does it mean for a virus to be airborne?

For a virus to be airborne means that it can be carried through the air in a viable form. For most pathogens, this is a yes-no scenario. HIV, too delicate to survive outside the body, is not airborne. Measles is airborne, and dangerously so: It can survive in the air for up to two hours.

For the coronavirus, the definition has been more complicated. Experts agree that the virus does not travel long distances or remain viable outdoors. But evidence suggests it can traverse the length of a room and, in one set of experimental conditions, remain viable for perhaps three hours.

How are aerosols different from droplets?

Aerosols are droplets, droplets are aerosols — they do not differ except in size. Scientists sometimes refer to droplets fewer than 5 microns in diameter as aerosols. (By comparison, a red blood cell is about 5 microns in diameter; a human hair is about 50 microns wide.)

From the start of the pandemic, the WHO and other public health organizations have focused on the virus’s ability to spread through large droplets that are expelled when a symptomatic person coughs or sneezes.

These droplets are heavy, relatively speaking, and fall quickly to the floor or onto a surface that others might touch. This is why public health agencies have recommended maintaining a distance of at least 6 feet from others, and frequent hand washing.

But some experts have said for months that infected people also are releasing aerosols when they cough and sneeze. More important, they expel aerosols even when they breathe, talk or sing, especially with some exertion.

Scientists know now that people can spread the virus even in the absence of symptoms — without coughing or sneezing — and aerosols might explain that phenomenon.

Because aerosols are smaller, they contain much less virus than droplets do. But because they are lighter, they can linger in the air for hours, especially in the absence of fresh air. In a crowded indoor space, a single infected person can release enough aerosolized virus over time to infect many people, perhaps seeding a superspreader event.

For droplets to be responsible for that kind of spread, a single person would have to be within a few feet of all the other people, or to have contaminated an object that everyone else touched. All that seems unlikely to many experts: “I have to do too many mental gymnastics to explain those other routes of transmission compared to aerosol transmission, which is much simpler,” Marr said.

Can I stop worrying about physical distancing and washing my hands?

Physical distancing is still very important. The closer you are to an infected person, the more aerosols and droplets you may be exposed to. Washing your hands often is still a good idea.

What’s new is that those two things may not be enough. “We should be placing as much emphasis on masks and ventilation as we do with hand washing,” Marr said. “As far as we can tell, this is equally important, if not more important.”

Should I begin wearing a hospital-grade mask indoors? And how long is too long to stay indoors?

Health care workers may all need to wear N95 masks, which filter out most aerosols. At the moment, they are advised to do so only when engaged in certain medical procedures that are thought to produce aerosols.

For the rest of us, cloth face masks will still greatly reduce risk, as long as most people wear them. At home, when you’re with your own family or with roommates you know to be careful, masks are still not necessary. But it is a good idea to wear them in other indoor spaces, experts said.

As for how long is safe, that is frustratingly tough to answer. A lot depends on whether the room is too crowded to allow for a safe distance from others and whether there is fresh air circulating through the room.

What does airborne transmission mean for reopening schools and colleges?

This is a matter of intense debate. Many schools are poorly ventilated and are too poorly funded to invest in new filtration systems. “There is a huge vulnerability to infection transmission via aerosols in schools,” said Don Milton, an aerosol expert at the University of Maryland.

Most children younger than 12 seem to have only mild symptoms, if any, so elementary schools may get by. “So far, we don’t have evidence that elementary schools will be a problem, but the upper grades, I think, would be more likely to be a problem,” Milton said.

College dorms and classrooms are also cause for concern.

Milton said the government should think of long-term solutions for these problems. Having public schools closed “clogs up the whole economy, and it’s a major vulnerability,” he said.

“Until we understand how this is part of our national defense, and fund it appropriately, we’re going to remain extremely vulnerable to these kinds of biological threats.”

What are some things I can do to minimize the risks?

Do as much as you can outdoors. Despite the many photos of people at beaches, even a somewhat crowded beach, especially on a breezy day, is likely to be safer than a pub or an indoor restaurant with recycled air.

But even outdoors, wear a mask if you are likely to be close to others for an extended period.

When indoors, one simple thing people can do is to “open their windows and doors whenever possible,” Marr said. You can also upgrade the filters in your home air-conditioning systems, or adjust the settings to use more outdoor air rather than recirculated air.

Public buildings and businesses may want to invest in air purifiers and ultraviolet lights that can kill the virus. Despite their reputation, elevators may not be a big risk, Milton said, compared with public bathrooms or offices with stagnant air where you may spend a long time.

If none of those things are possible, try to minimize the time you spend in an indoor space, especially without a mask. The longer you spend inside, the greater the dose of virus you might inhale.
