Hegde apologises in LS for his remark against Constitution, says his words were twisted

Bengaluru,  Jul 9: Former Karnataka Chief Minister and Congress leader Siddaramaiah on Wednesday said that he was opposed to a tie-up with Janata Dal-Secular in the last Lok Sabha elections but the party high command did not listen to him.

"I had suggested that we should fight alone (in Lok Sabha elections) because JD-S votes would not have come to us and our votes would not have gone to JD-S," Siddaramaiah told reporters here.

Congress leader said that he was the only one to make the suggestion and he did not get support.

"I was the only one to raise a voice that's why it was not heard by (party) high command and I did not get support. We might have won over seven seats in parliament election if we had fought alone," he said.

After forming government in Karnataka in 2018 with support of JD-S, Congress had fought the 2019 general election in a pre-poll alliance with the party. Congress could only one seat of the 21 it contested and JD-S also won one seat of the seven it contested.

New Delhi, Feb 29: Amid the raging communal violence in the entire north-east Delhi earlier this week, there were people who were trying to save persons and families from the "other community" from the fury of the mobs of their own community.

Naeem Ali Pradhan, 34, from Shiv Vihar, helped at least 7-8 Hindus on the night of February 24 -- when the violence was at its peak-- escape to safer locations. Shiv Vihar is one of the worst affected areas in the violence.

According to Naeem Ali, that night mobs attacked dozens of shops on the road and later tried to enter inside the residential areas.

Suddenly, he spotted a group of youth who were looking hassled and frantically asking for directions.

"I saw them. Thye were Hindus who were trying to escape a mob looking to target them. They had lost their way inside the streets of our colony. I along with other Muslim men escorted them to the nearby Hindu locality," Naeem, who is also a member of the Aman Committee constituted by the Delhi police, told ANI.

"Several shops which were on the roads including some showrooms were attacked by a group. These Hindus were worried as a mob which was on the main road was attacking people. They asked me the address of a colony as they were unable to find their way," Naeem said.

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.
