Illegal migrants are SP, BSP vote bank: Amit Shah

Mumbai, Mar 29: Virologist Minal Dakhave Bhosale led from the front to create India's first coronavirus testing kit even when she was in the last stage of her pregnancy.

Bhosale's efforts paid the price with her team delivering the testing kit in a record time of six weeks.

Bhosale gave birth to a baby girl just a day before submitting the kit to the authorities for evaluation.

"It was like giving birth to two babies," Bhosale told PTI over the phone.

The virologist said both the journeys - that happened in parallel - were not without challenges.

"There were complications in the pregnancy while work on the test kit was on. The baby was delivered through cesarean," she said.

Bhosale said she felt that it was the right time to serve the people to help them in combating the coronavirus threat.

"I had been working for five years in this field and if I don't work in emergency situations when my services are needed the most, then what is the use?" she said.

Though Bhosale was not able to visit the office due to the pregnancy, she was guiding a team of 10 persons working on the project at Mylab Discovery in Pune.

The strong bonds forged with the team over the years and their support made it possible, she said.

Company's co-founder Shrikant Patole said just like drug discovery, test kits too go through a lot of quality checks to improve the precision.

He credited Bhosale for the success of the project.

The COVID-19 testing kit delivered by Bhosale's team will reduce the time taken for delivering a result to 2.5 hours from the prevalent practice of eight hours.

A pioneering approach to testing without compromising on the results was adopted, Bhosale said.

The Maylab test kit will cost Rs1,200, a quarter of Rs 4,500 per kit that the government has been spending on testing so far.

"I'm happy that I could do something for the country," Bhosale said.

As of Friday, only 27,000 of the 1.3 billion people were tested for the virus in the country.

According to experts, high scale testing is essential because it alone can ensure an early diagnosis of COVID-19 and lower down the fatalities.

The company is confident of ramping up the capacity at its plant in Lonavala to deliver 100,000 kits a week, Patole said.

He said the authorities are helping the company, including giving priority for shipping of the raw materials.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.

New Delhi, Jul 18: National carrier Air India on Friday said that it is in a ‘very challenging financial’ situation and is taking recourse to several initiatives, with a view to ensuring the continuance of its operations.

The airline, in a statement, noted that it has introduced the partially voluntary 'Leave Without Pay' (LWP) scheme on July 14.

"The scheme primarily enables employees to avail the benefits of proceeding on leave without pay on a voluntary basis. The LWP scheme has been introduced for grant of leave without pay and allowances for permanent employees for a period of six months or two years, which is extendable upto 5 years," the statement said.

"Air India had brought out similar scheme earlier... Several hundred employees have, in the past, availed of the LWP Scheme."

As per the statement, in the wake of the ongoing Covid-19 pandemic, there may be employees who are unable to attend their office duties in person on account of personal reasons.

"The LWP scheme enables employees to take a break from their office responsibility for a defined period of time with the approval of the management, while retaining their employment with the company," the statement said.

"They will continue to avail facilities such as passage, medical and housing at specified rates."

Accordingly, the LWP scheme provides the opportunity to employees to take up alternative employment with the approval of the management during the period of the said leave, the airline said.

"The LWP scheme is a win-win situation for both the management as well as employees as it provides flexibility to employees and simultaneously reduces the wage bill for the company," the statement said.

"It is important to note here that the Covid-19 outbreak has very seriously impacted the airline sector and currently, the airline operations of the company are a small fraction of the prior Covid level operations."

The airline said that employees are encouraged to apply for availing the benefit of the scheme, in the prescribed format, by August 15.

"The only addition in this scheme as compared to the earlier LWP scheme is that the management can pass an order requiring the employees to go on leave for a period of six months or two years (extendable upto 5 years) compulsorily taking into consideration 'Suitability, Efficiency, Competence, Quality of performance, Health, Non-availability of employee and Redundancy'," the statement said.

Furthermore, the airline said that this provision has been introduced for use, "very sparingly", with a view to ensuring that the overall efficiency of the organisation, improves and the management will ensure that this will be implemented with complete fairness and transparency as per prescribed procedure.

Consequent to the announcement of the scheme, Air India unions are discussing their strategy against the move which might involve legal recourse.

An Air India union leader on Friday told IANS: "This is going to affect the livelihood of many. Why not every employee of AI take LWP a few days every month. This way the burden can be shared."

"The motive of the top management is to save their money by snatching money from lower employees."

According to Air India PIM document, as on November 1, 2019, the airline, on a standalone basis (without subsidiaries), had around 14,000 employees, including fixed term contract staff.

The development comes as the Centre has re-initiated the airline's divestment plan with new norms.

Interestingly, this time, it has sweetened the deal by substantially reducing the debt on the airline's account books and offered a 100 per cent stake in the loss-making airline.

The last date for bid submission to acquire Air India has also been extended to August 31.
