Over 600 global academicians write to PM Modi, blame him for 'terrible state of affairs'

Wayanad, Mar 3: Anguished over the alleged delay in receiving flood relief from the Kerala government, a 42-year-old man committed suicide in Wayanad district, police said on Tuesday. Sanal Kumar, a native of Thrikaipatta in Meppadi near here was found hanging inside the temporary shelter built by his friends and local people on Monday. He was among the hundreds who had lost their homes in the August 2019 floods.

His home, built on a three cent plot, had been damaged partially in 2018 floods and completely in the 2019 deluge. Family members of the deceased alleged that it was due undue delay on the part of the authorities in allotting funds for rebuilding his house that drove Kumar to take the extreme step. Kumar was hoping to get a house under the Life Mission project, sources said.

A relative said Kumar had only 3 cent of land and had lot of debts. Even the Rs 10,000 assistance promised by the state government for the flood affected, had not reached him. Since the past two years he had filed several applications for assistance and apporached many revenue authroties for the promised government assistance, but it never came, the locals alleged.

According to K K Sahad, president of Meppadi Panchayat the deceased had some other financial issues and it was not the delay in rehabilitation that made him commit suicide. "It is true that he was not included in the first list of beneficiaries under the LIFE project as he had to have "pattayam" (land records) for his land.

However, he was included in the second list, thanks to the dilution in the norms that possession was enough for those who had no 'pattayam' for their property. The amount of Rs 4 lakhs was sanctioned for him, but was delayed a bit due to some technical issues."

Wayanad MLA C K Saseendran described it as an "extremely sad" development. As Kumar had some difficulties in producing the land recrods, the authroties had been unable to include his name in the LIFE housing scheme in the first phase.

The matter has been brought before the notice of the revenue authorities, he said. Vythiri Tahsildar, Abdul Hameed, visited Kumar's relatives this morning as the family members of the deceased wanted his presence before the body was taken for post-mortem.

"There was some technical issues with regard to the land as it falls within the adhivasi reserve. But they were occupying it for long. However, the issue has been sorted out and that his family members would be getting the eligibility amount of four lakhs," Hameed said.

Thiruvananthapuram, Apr 21: Not just in China, but in Kerala also robot is now playing a key role in the health workers' fight against COVID-19, thanks to the innovative spirit of a group of young minds and the support of the state Health Department.

Named "Nightingale-19", the robot is deployed to provide food and medicines among patients at the district coronavirus centre in Ancharakandi in Kannur district where a large number of cases have been reported.

The special display facility, attached to it, also allows patients to communicate with health workers and their relatives if necessary, the health minister's office here said.

Designed by the students of Chemberi Vimal Jyothi Engineering College with the support of the Health Department, the remote control-operated robot can carry food and water for at least six persons at a stretch.

The machine, which can travel up to one kilometre, distributes food, water and medicine in each room, a department statement said.

The robot would be disinfected after each use, it said.

Health Minister K K Shailaja inaugurated the new venture from here recently through the robot's video facility, the statement added.

Robots have been put to use in other parts of the country to help in the health workers' fight against COVID- 19.

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.
