Arun Jaitley resumes charge as Finance Minister after a month

New Delhi, Jan 30: In a major shift of strategy ahead of the Delhi assembly polls, the Bharatiya Janata Party (BJP) has decided to rope in its senior leaders for massive public rallies.

Its star campaigners like Prime Minister Narendra Modi, Union Home Minister Amit Shah, BJP chief JP Nadda, Uttar Pradesh Chief Minister Yogi Adityanath, and other union ministers would now be addressing massive public rallies in addition to ongoing neighbourhood meetings.

"The big rallies would begin from February 1. While 'Nukkad' meetings will take place till the last day of campaigning, there would be big rallies of the top leadership of the party, " informed a senior party leader.

Sources said the BJP has changed its strategy after the success of its grassroots contact programme as the party wants to consolidate its gains.

"As part of the reworked strategy the BJP has asked its various Mandals to organise public meetings of 10,000-15,000 people in each assembly segment to reach out to the masses," sources added.

While there are two planned for Prime Minister Modi, two have been planned for JDU chief and Bihar Chief Minister Nitish Kumar along with Nadda and Amit Shah. Yogi Aadityanath too would be addressing 12 rallies.

The party is leaving no stone unturned to secure massive gains, which it feels can be converted to victory in the forthcoming polls.

Party sources feel that the relentless campaigning under the guidance of Amit Shah and Nadda has ensured that the morale of party cadre is at an all-time high.

"The neighbourhood meetings have ensured that we have been able to make the people of Delhi aware of the lack of work under the Arvind Kejriwal led Aam Aadmi Party government. They have also been apprised about the anti-national views of the opponents and we think that this is expected to turn the polls into our favour," sources added.

Delhi is scheduled for assembly polls on February 8 and the results for the 70 constituencies will be declared on February 11.

As part of the new strategy, senior leaders like JP Nadda, Amit Shah, Uttar Pradesh chief minister Yogi Adityanath, ministers like Rajnath Singh and Smriti Irani would be holding public rallies in various parts of the city. Several other chief ministers from various BJP ruled states are also expected to be roped in for the campaign.

The strategy for reach out to the masses is an attempt at weakening the hold of AAP on Delhi. With positive feedback coming after the success of the neighbourhood meetings in the past week, the BJP is now looking to increase its potential reach with polls just days away.

Till now the party had deployed 70 union ministers to hold at least one public meeting and one 'padayatra' each as part of the campaign.

New Delhi, Mar 4: The Supreme Court on Wednesday revoked the ban of cryptocurrency imposed by the Reserve Bank of India (RBI) in 2018.

Pronouncing the verdict, the three-judge bench of the apex court said the ban was 'disproportionate'.

The bench included Justice Rohinton Fali Nariman, Justice S Ravindra Bhat and Justice V Ramasubramanian.

The Internet and Mobile Association of India (IAMAI), whose members include cryptocurrency exchanges, and others had approached the top court objecting to a 2018 RBI circular directing regulated entities to not deal with cryptocurrencies.

Advocate Ashim Sood, appearing for IAMI, submitted that Reserve Bank of India lacked jurisdiction to forbid dealings in cryptocurrencies. The blanket ban was based on an erroneous understanding that it was impossible to regulate cryptocurrencies, Sood submitted.

The petitioners had argued that the RBI's circular taking cryptocurrencies out of the banking channels would deplete the ability of law enforcement agencies to regulate illegal activities in the industry.

IAMAI had claimed the move of RBI had effectively banned legitimate business activity via the virtual currencies (VCs).

The RBI on April 6, 2018, had issued the circular that barred RBI-regulated entities from "providing any service in relation to virtual currencies, including those of transfer or receipt of money in accounts relating to the purchase or sale of virtual currencies".

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.
