Shaking head is one of the most common methods people use to get rid of water in their ears, but it can can also cause complications as Researchers have found that trapped water in the ear canals can cause infection and Brain Damage.

Researchers at Cornell University and Virginia Tech in US, revealed that shaking the head to free trapped water can cause brain damage in small children.

“Our research mainly focuses on the acceleration required to get the water out of the ear canal,” said Indian-origin researcher and study author Anuj Baskota from Cornell University.

“The critical acceleration that we obtained experimentally on glass tubes and 3D printed ear canals was around the range of 10 times the force of gravity for infant ear sizes, which could cause damage to the brain,” Baskota said.

For adults, the acceleration was lower due to the larger diameter of the ear canals. They said the overall volume and position of the water in the canal changes the acceleration needed to remove it.

“From our experiments and theoretical model, we figured out that surface tension of the fluid is one of the crucial factors promoting the water to get stuck in ear canals,” said Baskota.

Luckily, the researchers said there is a solution that does not involve any head shaking.

“Presumably, putting a few drops of a liquid with lower surface tension than water, like alcohol or vinegar, in the ear would reduce the surface tension force allowing the water to flow out,” Baskota said.

Once Water-Starved, Chennai’s Cantonment Area Now Boast of 13 Brimful Water Bodies

Once water-starved, Chennai’s Cantonment area and military station now boast of 13 brimful water bodies and recycling plants, and also generate their own electricity. Inspired by the innovation, the Ministry of Defence has directed its Estate Wing to implement the development work across all defence establishments.

The ministry has suggested Directorate General, Defence Estates (DGDE), an inter-services organisation of the ministry which directly controls the cantonment administration, to replicate the Chennai Cantonment area development model.

Water bodies — 13 in all– are revived and a water recycling mechanism was put in place at both Cantonment Board St. Thomas Mount cum Pallavaram and Military Station, where there was an acute shortage of water in 2018.

A senior Indian Defence Estates Service (IDES) officer said that additional storage space for two-crore-litre water was created. “Further, because of recycling plant, 2 lakh liters of treated water is used in these areas per day,” the officer said.

The board also created a waste management system where door-to-door collection of garbage is being carried out and then segregated into bio degradable and non-biodegradable. It is then treated in a bio-compost pit. Thereafter, biodegradable waste is put in centralised processing wind row system and then manure is created and made available for sale.

The board revived a green zone with around 2,000 plantations, set up solar power plants and a sewage treatment plant.

The solar power infrastructure set up in a year had generated electricity worth Rs 1 crore which is distributed within the cantonment areas.

Interestingly, the board has created a separate dumping zone for plastic bags. The board came up with an innovative idea of retrieval of ration milk and meat poly packets from consumers. It formalised collection and disposal, prevented littering and reaped financial benefits.

A senior Indian Army officer said the innovative idea was of Lieutenant General S.T. Upasani, who was the General Officer Commanding (GOC) of Dakshin Bharat Area. Lt Gen Upasani recently took charge as Director General of Information System, the crucial post in Indian Army which was lying vacant for the last two months.

Further, the board carried out campaign to revive green zone and planted 2,022 trees with 98 per cent survivability.

This development model is set to be replicated at 61 cantonments areas across the country that had been notified under the Cantonments Act, 1924, which was succeeded by the Cantonments Act, 2006. There are 62 cantonment areas. The overall municipal administration is managed by the cantonment boards, which are democratic bodies.

The ex officio president of the board is the station commander and the Chief Executive Officer, who is also the Member-Secretary of the Board, is an officer of the IDES or Directorate General, Defence Estates (DGDE). (IANS)
