Violence cannot solve any problem: PM Modi

Lucknow, Jul 15: As many as 122 alleged criminals were killed in over 6,000 encounters in Uttar Pradesh in the past three years, while 13 policemen also lost their lives during this period, a senior police official said.

He also said over 2,000 criminals were injured in police action, while over 13,000 of them have been arrested.

"Thirteen policemen have been killed in action in as many as 6,126 encounters (in UP), while as many as 122 criminals have been gunned down," Additional Director General of Police (Law and Order) Prashant Kumar said while sharing details of police encounters from March 20, 2017, to July 10, 2020.

As many as 13,361 criminals have been arrested, while 2,296 criminals were injured in police encounters, he said, adding 909 policemen were also injured in these incidents.

Referring to the Kanpur ambush in which eight policemen were killed, Kumar said, "Of the 21 named accused in the incident, six have been killed and four arrested so far. A hunt is on to nab the 11 other accused."

Eight police personnel, including a DSP, were gunned down by the henchmen of gangster Vikas Dubey in Bikru village of Kanpur on July 3.

Seven others, including a civilian, were injured in the attack after the police team entered the village past July 2 midnight to arrest the gangster.

Dubey was later killed in an encounter on July 10 after police claimed that he tried to escape from the spot in the Bhauti area where the vehicle carrying him from Ujjain to Kanpur met with an accident.

Kumar said overall there has been a decline in the crime rate in the state this year compared to the last year.

"A total of 579 instances of loot took place in the state from January 1, 2020, to June 15, 2020. This is 44.17 per cent less compared to the crimes committed in the same period in 2019, the ADG (Law and Order) said.

He said 33 incidents of dacoity have been reported in the state this year so far. It is 37.74 per cent less compared to the crimes committed in the same period in 2019 .

Similarly, 2,604 instances of burglary have taken this year so far and is 30.97 per cent less compared to the crimes committed in the same period last year, Kumar added.

He said 1,019 dowry-related deaths have taken place this year, registering a 6.34 per cent decline compared to the previous year.

As many as 913 incidents of rape have been reported this year so far, a decline of 25.41 per cent compared to the last year, Kumar said.

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.

New Delhi, Mar 20: Bodies of the four Nirbhaya convicts who were hanged on Friday morning at Tihar Jail have been sent to hospital for a post-mortem, following which it will be handed over to the families, according to an official.

After the hanging at 5:30 am today, the bodies were taken from Tihar Jail to Deen Dayal Upadhyay (DDU) Hospital for post mortem at around 8:20 am.

Tihar jail Director-General Sandeep Goel said that the bodies will be handed over to the families after the post mortem.

The families, however, will have to give a written undertaking that they will not make a public demonstration of the cremation or burial of the executed person.

The superintendent will also consult the District Magistrate and the Deputy Commissioner of Police for arrangements for the disposal of the body.

The post mortem comes in line with the Supreme Court's order in Shatrughan Chauhan's case in January 2014, which had mandated the same observing that there is a dearth of experienced hangman in the country.

"By making the performance of post mortem obligatory, the cause of the death of the convict can be found out, which will reveal whether the person died as a result of the dislocation of the cervical vertebrate or by strangulation which results on account of too long a drop," the apex court had said in its order.

"Our constitution permits the execution of death sentence only through the procedure established by law and this procedure must be just, fair and reasonable," the order added.

All four convicts in the 2012 Nirbhaya gang-rape and murder case -- Akshay Singh Thakur, Pawan Gupta, Vinay Sharma, and Mukesh Singh -- were hanged till death at 5:30 am this morning.

The case pertains to the brutal gang-rape and killing of a 23-year-old paramedical student in a moving bus on the night of December 16, 2012, by six people including a juvenile in the national capital. The woman had died at a Singapore hospital a few days later.

One of the adults accused had allegedly committed suicide in the prison during the trial, while the juvenile was released from a correction home after a period of three years.
