Evil power of Opposition causing deaths of BJP leaders: Pragya Singh

Mumbai, Apr 14: Activist and scholar Anand Teltumbde was arrested by the National Investigation Agency (NIA) on Tuesday after he surrendered before it in connection with the Elgar Parishad-Maoist links case.

Teltumbde surrendered at the NIA office at Cumbala Hill in south Mumbai following the Supreme Court's directives.

He was subsequently arrested by the NIA and shall be produced before a court here shortly, an official said.

Earlier, the scholar reached the NIA office in the afternoon along with his wife Rama Teltumbde and brother-in- law and Dalit leader Prakash Ambedkar.

Anand Teltumbde is the grandson-in-law of Dalit icon Dr B R Ambedkar, whose 129th birth anniversary is being observed on Tuesday.

Civil rights activist Gautam Navlakha, a co-accused in the case, also surrendered before the NIA in Delhi. His anticipatory bail plea was also rejected by the apex court.

According to the official, Navlakha will be produced before the court in Mumbai through video conference.

The Supreme Court on March 17 this year rejected the pre-arrest bail pleas of Anand Teltumbde and Gautam Navlakha, and directed them to surrender before the investigating agency.

Teltumbde, Navlakha and nine other civil liberties activists have been booked under the stringent provisions of Unlawful Activities Prevention Act (UAPA) for having alleged Maoist links and conspiring the overthrow the government.

The apex court while rejecting Teltumbde and Navlakha's bail pleas on March 17, directed them to surrender before the prosecuting agency withing a period of three weeks.

The duo later sought extension of the time.

On April 9, the Supreme Court extended the time by one week by way of last chance.

The activists were booked initially by Pune Police following violence that erupted at Koregaon-Bhima there.

According to police, the activists made inflammatory speeches and provocative statements at the Elgar Parishad meet held in Pune on December 31, 2017, which triggered violence the next day.

The police also said these activists were active members of banned Maoist groups.

The case was later transferred to NIA. Teltumbde and Navlakha were given interim protection by the Bombay High Court while their pre-arrest bail pleas were being heard.

After the high court rejected their applications, the duo approached the Supreme Court.

New Delhi, Jul 20: Alleging that 2,426 companies have "looted" people's savings to the tune of Rs 1.47 lakh crore from banks, Congress leader Rahul Gandhi has asked if the Prime Minister Narendra Modi led government will conduct a probe into it to punish those guilty.

"2,426 companies looted 1.47 lakh crore rupees of people's savings from banks. Will this government investigate this loot and punish the culprits?" Gandhi said on Twitter, without elaborating.

"Or will it allow them to flee like Nirav and Lalit Modi?" he asked.

Gandhi's attack came after media reports claimed that the All India Bank Employees Association (AIBEA) had released a list of 2,426 borrower accounts that have been categorised as “wilful defaulters” with dues amounting to Rs 1,47,350 crore to the banking system.

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.
