Lt Col Shrikant Purohit greeted with flowers, says ‘I am happy’ with SC bail

Mar 5: The Kerala government has given its nod to a proposal aimed at encouraging students aged between 18 and 25 years to take up part-time jobs while pursuing education so as to help them gain work experience and hone their skills.

The government has decided to accept the proposal as a policy decision at the Cabinet meeting held on Wednesday, an official press release said.

The aim is to ensure that in a fiscal, 90 days of work is assured for students in government departments, local body organisations, PSUs and private companies.

This will help in developing a work culture among students.

Honorariums will be given to students by the organisations employing them part-time, the release said.

Students aged between 18 and 25 years will be permitted to become part of the scheme which will help them to gain work experience and hone their skills, the release added.

In another decision, the government decided to release Rs 26 crore from the Chief Minister's disaster relief fund for providing compensation to farmers who suffered crop loss during the 2018 floods.

May 7: Accusing the BJP government in Karnataka of "medieval barbarism" and treating migrants as worse than "bonded labourers", CPI(M) general secretary Sitaram Yechury on Wednesday hit out at the state's decision to stop workers from returning to their homes in different parts of the country citing requirements of the construction sector.

The Karnataka government has withdrawn its request to the railways to run special trains to ferry migrant labourers to their home states, hours after builders met Chief Minister B S Yediyurappa to apprise him of the problems the construction sector will face in case they left.

"This is worse than treating them as bonded labour. Does the Indian constitution exist? Are there any laws in the country? This BJP state government is throwing us back to medieval barbarism. This will be stoutly resisted,” Yechury said in a tweet.

The railways is running Shramik Special trains to ferry to their home towns migrants who were stranded at their places of work during the lockdown.

So far, it has run more than 115 such trains.

The Principal Secretary in the Revenue Department N Manjunatha Prasad, who is the nodal officer for migrants, had requested the South Western Railways on Tuesday to run two train services a day for five days except Wednesday, while the state government wanted services thrice a day to Danapur in Bihar. However, later, Prasad wrote another letter within a few hours that the special trains were not required. Several migrants in the city were desperate to return home as they were out of jobs and money.

Yechury also lashed out at the central government over reports that it owed states and industry Rs 3 trillion and accused the centre of shifting the burden of fighting the pandemic to the state governments.

“While shifting the entire burden of fighting the pandemic on to the State governments, Modi government is not even paying their legitimate dues. After November 2019, Centre has not paid the GST compensation dues for the rest of the financial year, i.e., March 2020.

“Modi government has the right to loot while crores of people & States are left with nothing but the right to starve?,” he tweeted.

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.
