Amity University confers honorary doctorate on Thumbay Moideen

Bengaluru, Feb 27: About 60kg of unaccounted gold ornaments worth Rs. 21 crore were unearthed by officers of the Commercial Taxes Department of Karnataka Government.

The ornaments were recovered after the department conducted surprise inspections and raided business premises of wholesale jewellery dealers in Ranganatha Mansion and Sakalajee Market in Chickpet area of Bengaluru on Tuesday.

"The raid was based on information that many traders from other states visit the city and carry gold jewels without any valid documents and supply it to local jewellers without invoices," said Srikar MS Commissioner of Commercial Taxes in a statement.

The officers raided the premises of 23 jewellers and found 60 kg gold ornaments in stock which were not covered by valid documents. A penalty was levied on the undocumented ornaments.

"It is informed that the enforcement wing is keeping a close watch on the interstate movement of gold, silver and all the dealers in the state are hereby advised not to buy any goods without valid purchase invoices, added Srikar MS.

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.

Kalaburagi, Feb 20: All India Majlis-e-Ittehadul Muslimeen (AIMIM) leader Waris Pathan on Wednesday said that 15 crore Muslims can dominate 100 crore Hindus.

"The time has now come for us to unite and achieve freedom. Remember we are 15 crore but can dominate over 100 crores," said Pathan while addressing an anti-CAA rally here.

"They tell us that we have kept our women in the front - only the lionesses have come out and you are already sweating. You can understand what would happen if all of us come together," he said.

The CAA grants citizenship to Hindu, Sikh, Jain, Parsi, Buddhist, and Christian refugees from Pakistan, Afghanistan, and Bangladesh, who came to India on or before December 31, 2014.

Protests have erupted across the country against the Citizenship Amendment Act (CAA), the National Register of Citizens (NRC) and the National Population Register (NPR).
