Declare PFI as anti-national terror outfit, arrest its leaders: VHP

Thiruvananthapuram, Feb 6: The 105-year-old Bageerathi Amma who scripted history when she appeared for her fourth standard exam in last November becoming the oldest learner of the Kerala State Literacy Mission has passed her exam with 74.5 per cent marks.

This grandmother from Parakulam in Kollam district of Kerala Bageerathi Amma has six children and 16 grandchildren.

Speaking to news agency ANI, CK Pradeep Kumar, district co-ordinator of State Literary Mission said on Wednesday, "Bageerathi Amma has passed her exam with 74.5 per cent marks. It is really an inspiration for others to follow her and continue their education," he said.

Ms Bageerathi had to stop her education at the age of nine when she was in Class 3 as she had to take care of her younger siblings.

Her yearning to continue her studies was fulfilled with the help of officials of the Literary Mission who helped her to realize her dreams. She scored 205 marks out of a total of 275 in the fourth standard equivalency examination.

The Kerala State Literacy Mission Authority is an autonomous institution under the General Education Department, Government of Kerala.

The programme aims to develop literacy skills through continuing education, provide chances of each and everyone interested in learning, enable the learners to make use of their learning in their daily life and ensure Secondary-level education to the whole of Kerala.

The main beneficiaries of this programme are illiterates, neo-literates, school drop-outs and those interested in lifelong education.

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, Jul 10: Alarmed by the surging COVID-19 cases across the state, especially in Bengaluru, Karnataka Chief Minister BS Yediyurappa on Thursday urged the state capital’s residents not to visit their villages to prevent the infection’s spread.

“I urge the people of Bengaluru not to travel to their villages and prevent the infection from spreading in rural areas,” Yediurappa told reporters.

Admitting that the battle against the virus would be long, he said that the fight against COVID-19 could be won only through persistent efforts and with people’s cooperation with the frontline ‘warriors’.

“Combating the pandemic through preventive measures, providing treatment to the infected and saving lives are our priority,” he said.

With a record 2,228 positive cases on Thursday, the southern state’s COVID-19 tally shot up to 31,105, including 17,782 active cases, while 457 people have died of the infection till date, 17 just in the last 24 hours.

Of the new cases in the state, Bengaluru accounted for 1,373, taking its tally to 13,882, including 10,870 active, while 177 have succumbed to the virus since March 9.

No deaths were, however, reported in the city on Thursday.

Of the 457 patients in intensive care units (ICU) across the state, 292 are in Bengaluru hospitals.

Since unlock began on June 1, COVID-19 cases shot up to 15,242 on June 30 from 3,221 on May 31 and to 31,105 in 9 days since July 1.

Similarly, in Bengaluru, positive cases shot up to 4,555 on June 30 from 358 on May 31 and rose to 13,882 in 9 days since July 1.

The Chief Minister also appealed to all legislators of the ruling and opposition parties to give priority to contain the disease in their Assembly segments.

“Visit the COVID-19 designated hospitals and inspect if the required facilities are in place and bring any shortcomings to our notice,” the CM said
