Mumbai’s shame: Dying woman molested on bridge during stampede

Mangaluru, May 23: Two more persons tested positive for covid-19 in Dakshina Kannada today taking the district's tally to 65.

One among them is a 30-year-old man who had returned from Maharashtra and was under quarantine. He underwent test at a private lab and was tested positive.

The other one is a 41-year-old woman who is a resident of Shirlalu in Beltangady and had symptoms of influenza-like illness. 

She was urged by residents in the surroundings of her house to go for a test. She was shifted to Wenlock COVID hospital in the morning on Saturday.

Bengaluru, Jan 8: Accusing the BJP of running a "fake news factory" at full potential, former chief minister Siddaramaiah on Tuesday said according to reports only Rs 669 crore of additional flood relief funds are being released by the Centre for the state as opposed to the ruling party's claim of Rs 1,869.85 crore.

Reacting to his attack, the State BJP unit, without clarifying on the actuals of the amount being released, said it believed in speaking the truth and not spreading lies.

Siddaramaiah, leader of the opposition in the state assembly, tweeted: "Reports from State govt officials tells that only Rs 669 crore of addl funds (sic) are released in 2nd instalment as opposed to the claim of Rs 1870 Cr by @BJP4Karnataka leaders. At a time when manufacturing industries are closing, BJP's fake news factory is running at full potential!!"

Calling BJP leaders "devotees of the God of lies," he said in another tweet that Prime Minister Narendra Modi released an additional Rs 669.85 crore moved by Chief Minister B S Yeddyurappa's plea, taking the total amount to Rs 1,869.85 crore. He said it was funny that they were attempting to depict the total relief amount as 1200+1869.85 equalling to Rs 3,069.85 crore.

Siddaramiahs tweet was in response to Karnataka BJPs tweet last night claiming that the High-Level Committee (HLC) Chaired by Union Home Minister Amit Shah has approved the release of Rs 1869.85 crore as central assistance to the state towards flood relief. This was in addition to Rs 1200 crore already released by the Centre in October 2019, the BJP unit had said.

On Monday, the HLC had approved additional central assistance to seven states affected by floods last year, from National Disaster Response Fund (NDRF), including Karnataka.

While a PIB release states that Rs 1869.85 crore was approved for Karnataka, according to sources in the state government the figure was inclusive of Rs 1,200 crore released in October. Earlier in the day, Chief Minister B S Yediyurappa while expressing confidence that more funds will be released in later stages, maintained that Rs 1869 crore has been released in addition to Rs 1,200 crore earlier, and thanked Prime Minister Narendra Modi.

"...funds will never be enough, they (central government) will release in stages, they have released such big amount- earlier Rs 1200 crore, now again Rs 1869 crore- I thank Prime Minister Narendra Modi for it," he told reporters here.

Revenue Minister R Ashoka said the state government will press for more funds in the days to come, and the state government will fulfil promises made to those hit by floods.

Karnataka faced two spells of unprecedented rains and floods last year, resulting in widespread damage to life and property, following which the state government had submitted a report to the centre claiming loss was to the tune of about Rs 38,000 crore.

Reacting to Siddaramaiah's attack of "fake news factory" against it, the state BJP tweeted "Ayyo @siddaramaiah Avare, We surrender to You as we are incapable of running Fake News Factory like You or @INCIndia.

We believe in speaking the Truth like Gandhiji, not spreading lies like Goebbels. Kannadigas still remember the "Lies Bhagya (a scheme)" you gave them as CM from 2013-18."

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.
