OMG! SBI collected Rs 1771-cr charges from below minimum balance accounts in April-Nov

Bengaluru, Mar 15: The week-long ban imposed by the Karnataka Government from Saturday is yet to get a total response in the State to fight against the spread of killer disease Coronavirus (COVID-19).

The ban has witnessed a considerable reduction in the travelling public by Bus and train. Bus terminal and Railway stations wore desert look or only a very few public travelling. KSRTC, which was maintaining service for every 10 minutes once between the State Capital and to City of Palaces, was forced to cancel most of the service due to very little patronage. 

"We were left with no option but to cancel the fleet since there are no passengers," sources at the KSRTC Bus terminal told media persons.

Bengaluru, Feb 6: A 33 -year-old techie who was on the run after allegedly bludgeoning her mother to death and attempting to murder her brother at their house near KR Puram early on Sunday was arrested along with her friend from a hotel in Port Blair, Andaman and Nicobar Islands, on Wednesday morning.

C Amruta and Sridhar Rao were produced before a court in Port Blair to get a transit warrant, deputy commissioner of police (Whitefield) MN Anuchet said. Police initially thought she had committed the crime as she was unable to repay a loan of Rs 15 lakh and feared being humiliated by the lenders.

"But now we strongly suspect that Amruta and Rao were in a relationship, which was opposed by her mother and brother. We don't see any other reason for her to attack her family members. We can get more details only after questioning the duo," another police officer said, adding, "The most important question is: Did Rao know Amruta was going to kill her mother? Or he got to know about it only later? He'd booked their air tickets to Port Blair on January 31 itself."

Rao and Amruta worked together in a software company in Whitefield till 2017. "Then they joined different firms and were in constant touch," police said.

Preliminary probe revealed the duo flew to Port Blair by catching a flight from Kempegowda International Airport (KIA) at 6.30am on Sunday. CCTV footage had shown Rao - wearing a full-face helmet and carrying a backpack - waiting near Amruta's house on a gearless scooter on Sunday morning. After she arrived, they chatted for a while before riding away. They arrived at KIA on the same bike, police said.

"We checked the passengers' list at KIA for that day and found Amruta's name. With the help of Port Blair police, we traced the duo to a hotel," an investigating officer said.

On Sunday morning, Amruta hit her 54-year-old mother C Nirmala on the head with a digging bar. She later stabbed her younger brother C Harish in the neck. Harish collapsed and thinking that he was dead, she left the house.

In his statement to police, Harish stated, "Around 4.30am, Amruta entered my room and stabbed me. I asked her what was wrong. She said she had a debt of Rs 15 lakh and didn't want the debtors to harass me and our mother."

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.
