Hinduism allows Hadiya’s father to kill her and go to jail: Saffron leader

Bengaluru, Jan 6: Students and teachers from various colleges in Bengaluru gathered at the Town Hall in the city to protest against the violence which broke out at the Jawaharlal Nehru University (JNU) campus in New Delhi on January 5.

The students raised slogans against Home Minister Amit Shah and Delhi Police.

Placards that read 'The more you attack, the stronger we become', 'Take off your masks terrorist', 'With JNU' were seen during the protest.

"We are here to protest against the incident that took place at JNU with our brothers and sisters. What Delhi Police did was shameful and they should have taken charge of the situation long before and not waited for three hours. We stand with JNU," Nisha, a protestor told ANI.

Professors present at the protest expressed regret over the incident and said attacks on the universities is a sick situation in the country.

"This is sick, where have we come to -- violence in the universities? I was so safe when I was studying in college; what we are giving to our students is horrible," said Sangeeta, a professor present at the protest.

Politicians, cutting across party lines, have condemned the attack on students in JNU and demanded strict action against those found guilty.

More than 18 students were taken to the AIIMS Trauma Centre after a masked mob entered the JNU campus and attacked them and some professors with sticks and rods.

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.

Bengaluru, Jan 12: Protesters plan to intensify their anti-Citizenship (Amendment) Act movement from sit-down satyagrahas and rallies to street and door-to-door campaigns in different parts of the city.

The street campaigns began on January 1 with 20-30 volunteers of Hum Bharat Ke Log, reaching out to people in Koramangala and Whitefield and explaining the CAA, National Population Register (NPR), National Register of Citizens (NRC) and related issues. They have organised four campaigns.

According to Zia Nomani, member of Hum Bharat Ke Log, the campaign will intensify soon. “Over 200-400 volunteers will organise nukkad sabhas and other activities around JP Nagar and Banashankari,” Nomani said.

She added that though protests began as a medium for people to vent their concerns, more needs to be done.

“We have realised that many people have begun working on their personal documents and want to help them understand what CAA is all about,” Nomani said.

Volunteers will talk to people at street junctions, discuss issues and run signature campaigns. They say: “Our movement is focussed on reaching out to people. Pro-CAA workers too started a door-to-door campaign last week.”

Avani Chokshi, an advocate who participated in a campaign, said though people had a cursory idea about these issues, they didn’t know the details. “It through such campaigns that we can reach more people. It’s important to talk to people who haven’t made up their mind about the issues or are even pro-CAA,” said Avani, adding, “It hard to combat hatred in a short span of time. The movement needs to be sustained.”

Activist Geeta Menon, who has been at the forefront of the street campaign, says they were heckled at some places.
