Chennai techies excel

Two former students of a college in Kodambakkam make it to a special list by Forbes, for their innovations in health care

While he and his team have developed a compact affordable device to treat pre-natal jaundice, she is working on a software platform to help addicts free themselves of substance abuse.

Meet Vivek Kopparthi and Akshaya Shanmugam, who now work in the United States.

A few years ago, they went to the same college.

Alumni of Meenakshi Sundararajan Engineering College in Kodambakkam, the two have made it to the “Forbes 30 Under 30” list, which recognises excellence in professionals aged under 30. Vivek is on the list released for 2017; and Akshaya, on the one for 2018.

Social impact

The son of Srinivasa Rao, a first-generation learner and Mangadevi, who believes employees in her small unit are family, Vivek says he hopes to make a social impact with the device, and is not interested in making money out of it.

“The World Health Organisation says that in South East Asia India, Myanmar and Africa, roughly 5.4 million infants go untreated for jaundice, every year. Nine percent of them either die or suffer permanent brain damage, every day. Our device, which uses light to treat jaundice, would be among the most affordable in the market, as it based on simple plug-and-play technology that can run on solar power or batteries. The device has just four pieces, no complicated machinery and not much training is required to use it,” explains Vivek, who is co-founder and CEO of NeoLight, a healthcare company that engineers and designs solutions for newborns in need of neonatal medical care.

Vivek is looking for organisations to tie up with him to supply the devices.

Overcoming addiction

His senior at college, Akshaya was part of team that was recognised for its work on creating a software platform to help addicts shake off their dependence.

“What we have is a software platform that is capable of collecting data from wearable sensors like smartphones and watches, basically Android devices that help us understand the behaviour of addicts and the triggers associated with the behaviour. Finally, we also give them personalised interventions to help them recover,” explains Akshaya, who has co-founded Lumme Labs and whose first target are smokers.

“This work is an outcome of research conducted at the University of Massachusetts and the Yale School of Medicine. Our work is funded and overseen by the National Institutes of Health. We have conducted two national-scale clinical trials in which we demonstrated that we can automatically detect smoking with an accuracy of 95% and predict smoking events six minutes in advance,” she explains.

Their college secretary K.S. Babai, says that she is very proud of the achievements of her students.

“Both of them did very well in academics when they were with us. We recognise leadership qualities in students and encourage them to organise events where they can showcase their capabilities,” she says.

The fun way of learning science goes places

Trend-setters: Infinite Engineers is working on an educational project involving both adults and young children.
Trend-setters: Infinite Engineers is working on an educational project involving both adults and young children.

Chennai-based enterprise spreads mission to Singapore

Their realisation during college that there was more to learning than marks brought this team of seven youngsters to start ‘Infinite Engineers’ to impart science concepts through hands-on experience. Now, this Chennai-based social enterprise is making headway in education institutions in Singapore too.

Started in 2014 during their final year in college, the ‘Infinite Engineers’ conducted workshops for schools to make science learning an enjoyable experience in Chennai. To equip teachers with simple tools to impart science lessons, they designed ‘Dexter Box,’ a kit with prototype science experiments aligned with the school curriculum of classes VI to IX.

S. Harish, co-founder of Infinite Engineers, said, “Children get to learn about concepts from their lessons. For instance, we provide an experiment module to help students conduct nutrient test, learn about sprinkler and drip irrigation and human anatomy through simple activities. We have reached about 10,000 children in 300 government schools and 20 private schools so far in five districts.” Each ‘Dexter Box’ has 12 types of experiments, games and activity based on the syllabus. “The challenge is to design the experiments to demonstrate within the class hours. We are now focussing on designing Dexter Boxes for primary school children,” he said.

At an interactive session organised by Singapore International Foundation at St. Luke’s Eldercare, Singapore, Sruthi Sadanand, one of the team members pursuing masters degree in the country, said she had identified the potential for their enterprise there and reached out to schools. “There is a robust environment for social enterprise to flourish in Singapore. If we prove we can add value to society, the start-ups could get financial aid too,” she said. “We have joined hands with Air Amber, another social enterprise in Singapore, for an inter-generation project wherein children and aged persons are involved in trying out experiments together. We are also launching a study on how the tools help the elderly and children with autism,” she said. The enterprise plans to launch online stores soon.

Tributes paid to renowned neurologist

Former Governor of West Bengal Gopalakrishna Gandhi paid rich tributes to the late neurologist Krishnamoorthy Srinivas at the Buddhi Immersion 2017, a workshop on the Brain, Mind and Integrative Medicine, held in the city on Friday. Mr. Gandhi said Dr. Srinivas had a microchip of a memory with a giga byte voltage containing everything in tight configuration and it could be unravelled at the slightest touch. Dr. Srinivas had the knack to describe an event, relate an episode or explain a phenomenon with sparkling clarity.

Mr. Gandhi said, “If you had to mention a name but were struggling, he (Dr. Srinivas) would complete the name, the background, ancestry, the signs of the zodiac, the traits of personality, the foils and foibles and it was only his highest professional rectitude which kept him from further going into the person’s medical history.”

Mr. Gandhi recalled a pertinent conversation with Dr. Srinivas about old age and the reasons for forgetfulness wherein he said the main reason for one to forget was not that they had forgotten but they did not choose to remember, which meant they did not register with due care what was being said to them.

Book released

“Dr. Srinivas said that if only they had registered it with due attention, they would not have experienced what seems to be the case of forgetfulness. So if you are interested in something, you are not likely to forget,” Mr. Gandhi recalled. He released the book ‘Autism: The Buddhi Book’ written by Ennapadam K. Krishnamoorthy and Subbulakshmy Natarajan on the occasion.

B.N. Gangadhar, director of NIMHANS, delivering the Dr. Krishnamoorthy Srinivas Lecture 2017, talked on the subject ‘Yoga for Integrative Mental Health: Neurobiological Evidence’.

City’s start-up aims to recycle e-waste from households

eWasteCF18nov2017

Non-functional mobile phone chargers, adaptors, calculators, old wires, bulbs, printers, and toners are all part of the e-waste generated at offices, industries, and even households. These mostly get into the regular garbage bags.

Green Era Recyclers, a seven-month-old start-up by Prasanth Omanakuttan and Syam Premachandran, looks at recycling the e-waste generated in the city. In the last seven months, it has collected and recycled eight to 10 tonnes.

The firm has recently got a five-year authorisation from the Tamil Nadu Pollution Control Board to recycle 150 tonnes of e-waste annually.

According to Mr. Prasanth, a study on the e-waste inventory shows that Coimbatore generates nearly 2,500 tonnes of e-waste a year. However, most of it goes unsegregated.

The waste batteries, cartridges, displays, and printers are all collected from institutions, a few houses, and industries and dismantled. The waste is segregated into hazardous and non-hazardous and the non-hazardous waste is recycled. “We also try to recover a lot of materials and refurbish some products,” he said.

Green Era is in talks with Coimbatore Corporation to collect e-waste from houses in one or two wards initially. “We have designed a special bin for households. It has four compartments to collect bulbs, wires, printers and toners, and miscellaneous items. We will pay an amount for most of these and collect them,” he says. The civic body has asked for some more details on recycling and the company will submit the information in a week or so. The preliminary recycling will be done in Coimbatore and the hazardous waste will be sent to Chennai for safe disposal.

Started with an investment of ₹15 lakh, the start-up also has a research unit that designs and develops machinery for recycling, “We now have shredder, extruder, and cable stripper,” says Mr. Prasanth. If the machinery available in the market is purchased, a large-scale recylcing plant needs at least ₹2 crore investment. The start-up has machinery that costs much less and plans to commercialise these too.

“We will go for external funding after developing the machinery,” he said.

Techie on a monsoon mission

SriramCF17nov2017

A software engineer is offering guidance to anyone seeking to set up a low-cost rainwater harvesting system

Sriram Vasudevan, a software engineer, uses his free time for work involving hardware. Not the hardware you associate with computers. He’s working with PVC pipes, L-joints and valves and other material necessary to build rainwater harvesting (RWH) systems. Having set up a self-designed, cost-effective RWH structure at his house in Ramapuram, he is helping others install such structures at theirs.

He had been researching intensely on how to install cost-effective RWH structures before devising such a model himself. He says this work is motivated by a desire to solve water-related problems in the city. Sometime ago, he posted an announcement on Facebook, expressing his desire to guide anyone who wants to install such an RWH structure. “My friend Balaji set up an RWH structure at his house recently and I was greatly inspired by it. I believe a good RWH structure in each house will help solve many water-related problems in the city,” he says. Here’s how this model works.

“The rainwater that gets collected in someone’s terrace should be directed to their borewell, well or sump,” he explains. In regular RWH systems, the collected rainwater is directed to a rainwater harvesting pit dug near the house. This pit has a layer of coarse pebbles to help filter impurities and channel the water underground directly. In a variation of this model, Sriram suggests that a valve be placed in the RWH pipes.

This valve is capable of clearing out the impurities, thereby helping bypass the need for a rainwater harvesting pit.

Sriram says channeling the collected rainwater directly to the borewell will help improve water quality.

“There will be a evident change in water quality and taste, post-monsoon,” he says.

He points out that in case of any overflow in the collection system, an extra tank can always be set up to store excess water.

Sriram has already helped two residents set up RWH structures at their houses.

School of rock: in conversation with geologist C Singaraja

GeologistCF08nov2017

Award-winning geologist C Singaraja explains how what’s happening beneath our feet impacts our lives and health

It’s Shawshank Redemption in real life. Or, if you prefer, Erin Brockovich. In the first, a banker (Tim Robbins) charged with murder is sent to a high-security prison where he uses his fine knowledge of rocks to dig a tunnel and escape.

In the second, based on a true story, Erin Brockovich, a law-firm assistant (Julia Roberts) investigates a chemicals company that releases untreated hexavalent chromium thus contaminating groundwater and jeopardising the health of local residents.

Geologist Dr C Singaraja was recently conferred a Dr APJ Abdul Kalam prize for Young Scientist — 2017, by Marina Labs R&D, Chennai, a Medical Research Center and Biotechnology Company. The award was given in recognition of his study of groundwater. Rocks, water, contamination: how does he join the dots?

“I did my graduation and post graduation studies in Thoothukudi, and moved to Annamalai University for my M.Phil and doctorate work,” he says. “My paper for MPhil was on how tidal variation affects groundwater along the Cuddalore coast. My PhD thesis on the other hand was on the hydro-geo chemistry of groundwater in Thoothukudi district. This place has sea-water intrusion and heavy-metal pollution by industries. I checked the land for the presence of radon and fluoride and their effect on groundwater.”

He listed the findings. Groundwater is impacted by salt content in coastal regions. In inland areas the weathering of bed-rock leaches mica, fluorite and fluoro-apatite into groundwater. The report educates panchayats and builders about water quality, and the reasons why it gets contaminated.

Singaraja also worked as an assistant on a project that surveyed soil in Thoothukudi, Dindigul, Krishnagiri, Nagapattinam, Puducherry and Villuppuram. He prepared a groundwater quality index, and pointed to where people could find good aquifer zones.

The team tested and labelled water quality region-wise based on scientific parameters. “In Cuddalore district we showed how tidal waves and salt-pans impacted water salinity, and how this affected sea creatures. We devised a method to remove excess fluoride from water using natural materials,” he says

Since 2009 Singaraja has been part of several soil-testing projects and has written 40 papers on hydro-geology. “Rocks don’t change for millennia, but water content does, indicating what’s happening beneath our feet and how it impacts our lives and health.” He also studies what he calls medical geology. “It looks into the health effects of rocks,” he explains. For example, granite, a source rock, contains naturally-occurring uranium and radon, and exposure to weather makes uranium radio-active and radon into gas. These run into groundwater, making it unsafe.

Doing research on water quality in 100-plus villages was memorable. “Some villagers noticed the instrument we dipped in the water and accused us of poisoning their sources. Others knew what we were doing and asked us to check the water in wells in their homes. Still others requested us to bore wells for them. We helped farmers identify zones to dig for water.” That’s a lot of passion in someone who calls himself a reluctant geologist. “I wasn’t sure what I wanted to do after school. A cousin had studied Geology and was doing well with the Geological Survey of India. I joined VOC, Thoothukkudi, which has a well-known 85-year-old Geology Department. I soon warmed up to my subject.”

Talking about the water in Chennai, he says boiling drinking water will make it salt-free. “Store can water in porous mud pots, so the pH increases through air circulation. It’s good for health. Check common water for fluoride. Beyond 1.5 mg/litre it could cause yellowing teeth and problems with bones.”

He adds, “Never buy land or construct houses without first testing the soil for curability; and water for elements within permissible levels. Certain types of soil swell with water and shake the foundation. The effects of groundwater contamination show up slowly after regular intake. Rain-water harvesting purifies groundwater. So opt for preventive measures.”

He adds, “Geology is currently an important subject. Future wars will be fought over fresh water… Research on groundwater components can get you two Nobels — for Science and for Peace.”

Neurologist Krishnamoorthy Srinivas dies in Chennai aged 84

Chennai :

More than 50 years ago when many doctors were leaving India in search of green pastures, Dr Krishnamoorthy Srinivas returned home. The clinical neurologist, who had ensured free or subsidised but quality care for all his patients since then, breathed his last in a private hospital at Mylapore at 6.10am on Wednesday. He was 84.

“He went into coma on Sunday and never woke up,” said his son Dr Ennapadam S Krishnamoorthy, a neuropsychiatrist.

Senior doctors, patients, industrialists and several eminent people paid their last respects to Dr Srinivas who had always looked into his patients’ eyes and listened to them.

After landing in Chennai with three FRCPs and intensive training in Canada, Dr Srinivas worked in Voluntary Health Services, a hospital founded Dr K S Sanjeevi, and in the Public Health Centre at West Mambalam.

“I started my training in July 1959 at Montreal, Canada. Fifty-six years have passed since I entered neurology. Essentially, I am a clinical neurologist with interests in the welfare of patients, especially in patient care, in clinical diagnosis and teaching. I follow Sir William Osler’s obiter dictum—placing research after the above are done,” he wrote for a commentary in Neurology India journal in 2015.

Dr Srinivas belonged to the rare breed of doctors who encouraged patients to speak more in his consultation room.

One of his students, senior neurologist Dr AV Srinivasan recalled how he would tell his postgraduates. “Hurry, hurry, listen to the patient, he is giving us the diagnosis.”

He sent them for tests and prescribed medicines only if was convinced that they were necessary. “It is not that he did not believe in scans or other diagnostic tests. He used technology only to enhance his clinical skills,” Dr A V Srinivasan.

Though research came last, he has authored several papers in peer reviewed journals. He loved teaching and worked as an honorary professor at the Madras Medical College and in several other medical colleges.
He set up the Institute of Neurological Sciences at the VHS and brought eminent scholars in neurology to speak on fascinating topics such of the brain and mind that would interest not just doctors, but members of the public as well.

On Wednesday, as he bid adieu, one of his patients, 74-year-old R Venkatraman, said, “His work is done. He may now rest forever.”

The last rites will be held in the Mylapore crematorium at 5pm.
