Youth bursts cracker in 3-yr-old girl's mouth in UP

New Delhi, Jan 14: One of the four Nirbhaya gang rape convicts, who are scheduled to be hanged on January 22, moved a mercy plea before President Ram Nath Kovind to set aside the death sentence issued against him.

He also moved the Delhi High Court to set aside the death warrant issued by a trial court. This hearing is scheduled for Wednesday before a bench of Justices Manmohan and Sangita Dhingra Sehgal.

The petition, filed through advocate Vrinda Grover, seeks setting aside of the January 7 order issuing the warrant of his execution.

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.

Washington, Feb 12: US President Donald Trump said on Tuesday he would sign a trade deal with Prime Minister Narendra Modi if 'it was the right one'.

The two countries have been trying to reach a limited trade pact with lower tariffs, but talks have run into problems over issues with data privacy and e-commerce controls.

Trump further said that he is looking forward to his visit to India later this month where millions of people would welcome him. "He (Modi) is a great gentleman and I look forward to going to India. So, we'll be going at the end of the month," Trump told reporters in his Oval Office, a day after the White House announced dates of his anticipated India trip.

Responding to a question, the president indicated that he is willing to sign a trade deal with India if it is the right one. "They (Indians) want to do something and we'll see... if we can make the right deal, (we) will do it," said Trump, a fortnight ahead of his visit to the country as the 45th US president.

India's new Ambassador to the US, Taranjit Singh Sandhu told PTI that Trump's forthcoming visit is a "reflection of the strong personal rapport" between Trump and Modi. "It also demonstrates their strong desire to take the relationship to new heights," said Sandhu, who had presented his credentials to Trump in Oval Office last week.

Over the last three years, Trump and Modi have developed a personal friendship and in 2019, the duo met four times including their joint address before a strong 50,000 crowd of Indian Americans in Houston.

This year, they have spoken over the phone on two occasions, including the one over the weekend. "Just spoke with Prime Minister Modi," Trump told reporters on Tuesday in response to a question on his India visit.

Excited to travel to India later this month, said Trump referring to his conversation with Modi during which the prime minister apparently told him about the hundreds and thousands of Indians who would be there to welcome him in Ahmedabad.

Trump jokingly told reporters that now he will "not feel good" about the size of the crowd that he addresses in the US which is usually between 40,000 to 50,000. "He (Modi) said we will have millions and millions of people. My only problem is that last night we probably had 40 or 50,000 people... I'm not going to feel so good... There will be five to seven million people just from the airport to the new stadium (in Ahmedabad)," Trump said.

"And you know (it) is the largest stadium in the world. He's (Modi) building it now. It's almost complete and it's the largest in the world," Trump said. The two leaders are expected to joint address a massive public rally at the newly build Motera Stadium in Ahmedabad.

Being built at an estimated cost of USD 100 million, the Motera Stadium with a seating capacity of 100,000 spectators will be the world's largest cricket stadium overtaking the Melbourne Cricket Ground in Australia.
