Yoga is above everything, integral part of life: PM Modi

Ahmedabad, Jul 5: A woman police sub-inspector (PSI) with Ahmedabad Police was arrested and sent to three-day police remand, on Saturday, for allegedly accepting a bribe of Rs 20 lakh from an Ahmedabad-based businessman — accused in two rape cases — in exchange for not applying a stringent act against him.

According to police officials, Shweta Jadeja, PSI and incharge of Mahila police station (West) in the city, was arrested by a team of Detection of Crime Branch (DCB) officials in Ahmedabad on Friday after the complainant in the case, the rape accused, approached the Crime Branch and stated that Jadeja had allegedly demanded Rs 35 lakh form him, in exchange for not booking him under the Prevention of Anti-Social Activities (PASA) Act.

The PASA Act in Gujarat gives power to the police to detain an accused and send them to a prison away from their native district. The complainant claimed that he already paid Rs 20 lakh of the total amount to Jadeja on February 3.

On Saturday, a sessions court awarded Jadeja a three-day remand with the Crime Branch, which will end at 11:30 am on July 7. Following this, the PSI will undergo a medical check-up and be presented before the magistrate again.

“We had originally demanded a seven-day remand. The accused officer has been sent to three-day remand for further investigation in the case,” said a senior police official in Ahmedabad.

According to police, complainant Kenal Shah — managing director of GSP Crop Science Private Limited, a crop solution-based company in Ahmedabad — is allegedly facing two separate rape cases under IPC section 376.

PSI Jadeja was first entrusted with the investigation of a rape case against Shah in January this year, lodged at Mahila police station (West).

The rape case complaint is of 2019. Another rape case against Shah was being probed by Assistant Commissioner of Police (Crimes Against Women), Mini Josef, wherein the investigation was reportedly completed.

As per the remand application report filed by the police, Jadeja had allegedly threatened Shah through his brother Bhavesh Shah — a joint managing director at GSP Crop Science Private Limited — and initially demanded Rs 25 lakh for not applying the PASA Act against the accused. The bribe amount was then settled at Rs 20 lakh and in February, the accused allegedly paid the amount via an office accountant to one Jayubha, allegedly a representative of Jadeja, from a finance office in Jamjodhpur area of Ahmedabad.

The report further stated that after the initial amount was paid, a third complaint was allegedly made against Kenal by a security officer at his office, Yograjsinh, for criminal intimidation. After the third complaint, PSI Jadeja had contacted Bhavesh again and demanded an additional sum of Rs 15 lakh for not applying the PASA Act against Kenal. The complaint from the security officer was not converted into an FIR and Shah has not been jailed yet.

However, It was after the demand of Rs 15 lakh that complainant Kenal approached the Crime Branch on June 27. An FIR was lodged against Jadeja at Ahmedabad DCB police station under sections seven and twelve of the Prevention of Corruption Act, charging her for “public servant taking gratification other than legal remuneration in respect of an official act”.

“Now that we have received the remand of the accused officer from the court, we will try to trace and recover the alleged Rs 20 lakh amount she received in this case,” said Deepan Bhadran, Deputy Commissioner of Police, Ahmedabad.

Shweta Jadeja is a PSI of the 2016-’17 batch and a resident of Vastrapur in Ahmedabad, while her native place is in Keshod of Junagadh district. The police have not recovered the bribe amount she allegedly accepted as of late Saturday.

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, May 25: The pending class 10 and 12 board exams will be conducted by CBSE at 15,000 centres across the country instead of 3,000 centres planned earlier, Union HRD Minister Ramesh Pokhriyal 'Nishank' announced on Monday.

The exams, which were postponed due to a nationwide lockdown imposed on March 25 to contain the spread of COVID-19, will now be held from July 1 to 15.

"The class 10, 12 exams will now be conducted at over 15,000 exam centres across India. Earlier, CBSE was slated to hold exams at only 3,000 centres," Nishank said.

The decision has been taken to ensure social distancing at exam centres and minimise travel for students.

The HRD ministry has already announced that students will appear for exams at schools in which they are enrolled rather than external examination centres.

According to home ministry guidelines, there will be no exam centre in COVID-19 containment zones and states will be responsible for making transport arrangements for students to reach their respective centres.

Usually, board examinations are held at designated test centres to ensure minimum bias from schools and enable independent external invigilators to monitor the examination process.

While Class 12 exams will be conducted across the country, the Class 10 exams are only pending in North East Delhi, where they could not be held due to the law-and-order situation in the wake of protests against the amended citizenship act.

The CBSE class 10 and 12 board exam evaluation is being carried out from home.

The HRD ministry had earmarked 3,000 evaluation centres from where answer sheets would be distributed to teachers at their homes for evaluation and then collected.

Universities and schools across the country have been closed since March 16 when the Centre announced a countrywide classroom shutdown as one of the measures to contain the COVID-19 outbreak.

Later, a 21-day nationwide lockdown was announced on March 24, which came into effect the next day. It has now been extended till May 31. The board was not able to conduct class 10 and 12 exams on eight examination days due to the coronavirus outbreak.

Due to the law-and-order situation in North East Delhi, CBSE was not able to conduct exams on four examination days, while a very small number of students from and around this district were not able to appear in exams on six days.

The board had last month announced that it will only conduct pending exams in 29 subjects which are crucial for promotion and admission to higher educational institutions.

The modalities of assessment for the subjects for which exams are not being conducted will be announced soon by the board.

The schedule has been decided in order to ensure that the board exams are completed before competitive examinations such as engineering entrance JEE-Mains, which is scheduled from July 18-23 and medical entrance exam NEET that will be held on July 26.
