Narendra Modi becomes first sitting PM to visit Dharmasthala

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.

Jan 14: A police complaint was lodged on Tuesday against BJP West Bengal unit president Dilip Ghosh for his threat to "beat up" and "shoot' " anti-CAA protesters, whom he called "infiltrators".

The complaint was registered in Ranaghat police station of Nadia district by a Trinamool Congress worker Krishnendu Banerjee, who alleged that Ghosh was inciting communal passion.

Addressing a party rally on Sunday in Ranathat, about 80 km from Kolkata, Ghosh went ballistic, saying the governments in BJP-ruled Assam, Karnataka and Uttar Pradesh have shot dead "like dogs" those protesting against the new Citizenship (Amendment) Act.

Alleging there were one crore infiltrators in the state, Ghosh had accused them of destroying public property worth Rs 500-600 crore during the violent protests against the CAA last month

"Friends, please know these people who are opposing Hindus and Bengalis. In whose interest are they doing this? There are one crore infiltrators. They are having their meals and staying here on our money".

He accused the state's Mamata Banerjee government of remaining silent a spectator to the violence.

"This (violence) happened because there was neither any baton charge, nor firing, nor was any FIR filed. Why? Didi's police did not arrest anybody... because they vote for her".

He then referred to the three states ruled by the BJP.

"In Assam, Karnataka and Uttar Pradesh, our governments have shot dead these devils like dogs. They were taken elsewhere and then again cases were filed against them. They will come here, eat, stay, and then destroy property. Do they think this is their zamindari?"

He had said once a BJP government was installed in Bengal, "We will hit them with sticks, shoot them and also send them to jail. Our governments have done exactly that. Mamata Banerjee doesn't have the guts to do anything".

However, his incendiary comments did not meet the approval of sections in the party.

Union Minister Babul Supriyo came out with a tweet slamming Ghosh and distancing the BJP from the comments.

"Very irresponsible of Dilip Da to have said what he said. It is a figment of his imagination... BJP governments in UP and Assam have never resorted to shooting people for whatever reason," he tweeted.

Supriyo's tweet was retweeted by nominated Rajya Sabha member Swapan Dasgupta, considered close to both Prime Minister Narendra Modi and Home Minister Amit Shah.

But Ghosh did not budge and aggressively asked whether the party was being run by Shah or Supriyo.

"People comment according to their understanding. What I feel is that our governments have done it, and so I said all that. If we get a chance we will also do such things," he said, sticking to his earlier comments.

Supriyo also hit back. "Just as he has remarked 'whatever Babul Supriyo has understood he has said', similarly I am saying this is Dilip da's personal opinion, and it has no connection with the party".

New Delhi, Feb 29: India’s economy expanded at its slowest pace in more than six years in the last three months of 2019, with analysts predicting further deceleration as the global Covid 19 coronavirus outbreak stifles growth in Asia’s third-largest economy.

The gross domestic product (GDP) data released yesterday showed government spending, private investment and exports slowing down, while there is a slight upturn in consumer spending and improvement in rural demand lent support.

The quarterly figure of 4.7% growth matched the consensus in a Reuters poll of analysts but was below a revised - and greatly increased - 5.1% rate for the previous quarter.

The central bank has warned that downside risks to global growth have increased as a result of the coronavirus epidemic, the full effects of which are still unfolding.

Prime minister Narendra Modi’s government has taken several steps to bolster economic growth, including a privatisation push and increased state spending, after cutting corporate tax rates last September.

In its annual budget presented this month, the government estimated that annual economic growth in the financial year to March 31 would be 5%, its lowest for last 11 years.

Modi’s government is targeting a slight recovery in growth to 6% for 2020/21, still far below the level needed to generate jobs for millions of young Indians entering the labour market each month.

The annual GDP figure for the September quarter was ramped up from an earlier estimate of 4.5%, while the April-June reading was similarly lifted to 5.6% from 5%, data released by the Ministry of Statistics showed on Friday.

Capital Investment Drop

In the December quarter, private investment grew 5.9%, up from 5.6% in the previous quarter, while government spending rose by 11.8%, against 13.2% in the previous three months.

However, corporate capital investment contracted by 5.2% after a 4.1% decline in the previous quarter, indicating that interest rate cuts by the central bank have failed to encourage new investment. Manufacturing, meanwhile, contracted by 0.2%.

“It appears growth slowdown is not just cyclical but more entrenched with consumption secularly joining the slowdown bandwagon even as the investment story continues to languish,” said Madhavi Arora of Edelweiss Securities in Mumbai.

Many economists said that the government stimulus could take four to six quarters of time before lifting the economy and the impact of those efforts could be outweighed by the global fallout from the coronavirus epidemic that began in China.

“The coronavirus remains the critical risk as India depends on China for both demand and supply of inputs,” said Abheek Barua, chief economist at HDFC Bank.

Indian shares sank on Friday for a sixth session running, capping their worst week in more than a decade. The NSE Nifty 50 index shed 7.3% over the week, while the Sensex dropped 6.8%, the worst weekly declines since the 2008-09 financial crisis.

Separately, India’s infrastructure output rose 2.2% year on year in January, data showed on Friday.

A spike in inflation to a more than 5-1/2 year high of 7.59% in January is expected to make the RBI hold off from further cuts to interest rates for now, while keeping its monetary stance accommodative.
