RGGGH develops hand sanitiser, saves ₹31 lakh a year

The product is now being used in all its intensive care units, fever wards and isolation wards

An indigenously prepared hand sanitiser has turned profitable for the Rajiv Gandhi Government General Hospital (RGGGH). The largest public sector hospital in the city is all set to save nearly ₹31 lakh every year, after its own alcohol-based hand sanitiser was introduced in many units a few months ago.

Prepared in its own backyard by the College of Pharmacy (Madras Medical College), the hand sanitiser is now being used in all intensive care units, fever wards and isolation wards, such as for H1N1 influenza cases.

“Hand sanitisers are an important aspect of a health facility, particularly to a tertiary centre like us. On one hand, we have 12,000 outpatients visiting the hospital every day and another as 3,500 inpatients. On the other hand, we have a large population of medical professionals, including undergraduates, interns, surgeons and professors. It is vital to prevent hospital-acquired cross infections, and hence, we came up with the idea of developing our own hand sanitiser,” said R. Jayanthi, dean of RGGGH and MMC.

Reduced costs

Till February, when the in-house sanitiser was rolled out, RGGGH purchased commercially available hand sanitisers. The hospital’s monthly requirement was 1,000 units of 500 ml bottles; the annual requirement being 12,000 bottles. The cost of the marketed products ranged from ₹290 to ₹433 per 500 ml.

“The cost of procuring 12,000 bottles of a marketed product, considering an average cost of ₹341 is ₹40,92,000. Our hand sanitiser costs ₹82, inclusive of packing. So, the total cost for 12,000 bottles is ₹9,84,000. We will save ₹31,08,000 per year,” she said.

While this helped in cutting down cost, the hand sanitisers also reduced the need for using water for washing hands at a time of scarcity and it could easily be taken to different wards, Dr. Jayanthi said.

Jerard Suresh, principal, College of Pharmacy, MMC, said they prepared nearly 200 litres per batch of the lemon grass-scented hand sanitiser. It was tested for dermatological safety by the institute’s Department of Dermatology and efficacy against microbes by the Department of Microbiology.

Dr. Jayanthi said once they improve the capacity to make more, the hand sanitiser would be made available in the general wards of RGGGH. “Once we are self-sustained, we have plans to provide it for other government institutions. For this, we need licence and we are at it,” she said.

Mahindra Odyssea will set sail at the Manimuthar Dam

Tamil Nadu’s first solar-powered boat will soon operate at the Manimuthar Dam in Tirunelveli district. According to sources at the Kalakkad Mundanthurai Tiger Reserve, the boat will begin operations in the next 10 days.

On Friday, Anand Mahindra, chairman of the Mahindra Group, posted a tweet saying, “Mahindra Marine proudly joins #Go Electric – Go Green objective of the group by launching its first solar-electric boat for Tamil Nadu Forest Dept. She is a 24 pax harbour cruise boat, powered by a keel cooled electric motor with shaft, and propelled by a lithium-ion battery.”

Called Mahindra Odyssea, the 26-seater (including two crew members) boat is 11.8 m long and 4 m wide. One of its unique aspects is that it has a German motor (20 KW).

“It has a solar roof on top which can generate 3.8 KW of power. The solar roof will help the boat get partially charged while moving,” said Hiten Ghelani, chief executive officer and managing director of Mahindra Marine, told The Hindu.He said the idea was devised during a visit to Dubai and Europe.

“We started developing the boat and when we were ready with the first one — we received a tender from Tamil Nadu for a similar boat. We asked the team to visit us to try this boat and they came down,” Mr. Ghelani said. To a question on the cost of the boat, he said, “I won’t be able to give the exact details. On an average these boats would cost anywhere between ₹80 lakh and can go up to a crore. These can be customised depending on what the client wants,” he added.

Sources said that two more boats would be supplied in the coming days.

A team of researchers from Bannari Amman Institute of Technology, Sathyamangalam, has installed a smart fence for early elephant warning at Parsa Wildlife Reserve in Nepal.

The team headed by Sanjoy Deb, and comprising R. Ramkumar and L. Rajasekar, designed and developed the system with active support from the college management. The long range LASER-based smart fence has already been installed at two places in Sathyamangalam Tiger Reserve.

Since crop raiding by elephants was a major issue in areas located near Parsa Wildlife Reserve in Nepal, the fence was installed there in collaboration with the Nepal Biodiversity Research and Conservation Centre, a NGO based in Nepal. The team visited Nepal recently and installed the fence near the reserve area.

The team members said that the system was specially designed with minimum electronic components. Local team members in Nepal have been provided training in maintaining the system.

They said that the team was now working on improving its features and cost minimisation to make it a true global solution.

TA Pugalarasan: Chennai’s turtle man creates a sea change among locals

Pugalarasan hopes to have a small research vessel someday to study endangered marine life.

T.A Pugalarasan

On a chilly December morning in 2002, T.A Pugalarasan was walking on the beach in his fishing village Periya Neelankarai when he spotted a stranded sea turtle. He instinctively decided to save the turtle and swam 200 metres beyond the waves to release it back in the ocean. “I had seen several dead sea turtles on the shore. But that was the first time I helped a stranded turtle,” says Pugalarasan.

Like many youngsters in his village, Pugalarasan was initially indifferent to marine life and its conservation. There was even a time when he and his friends used to play with turtle eggs. Life took a different turn for him when he met conservationist Dr. Supraja Dharini, founder of the Tree Foundation.

“My entire perspective about the ocean and its life forms changed after I met Dr. Supraja. When I was younger, I did not know about sea turtles. So I would dig out their eggs and use them as balls to play cricket. They have a very soft shell, unlike other eggs, and so bounce off the ground. I still remember when I met her for the first time, I asked several questions like why we should put turtles back into the sea and why they should be protected,” adds Pugalarasan.

After interacting with Dr. Supraja, Pugalarasan realised that protecting sea turtles is like protecting the wealth of the ocean. Today Pugal is part of the Sea Turtle Protection Force (STPF) which comprises over 165 fishermen living along the Coromandel Coast. STPF is an initiative started by the Tree Foundation under the aegis of Dr. Supraja.

Over the years, Pugal and his STPF member have created a sea change in the attitudes of the local community towards the turtles. “We conduct many awareness programmes on endangered marine species in fishing villages, schools and colleges using dance, drama and documentaries,” says Pugal.

“In some fishing communities, the fishermen eat sea turtles. We have built a strong network of informers to save the turtles. We work jointly with the Marine Police, Fisheries Department staff and the Forest Guard,” he says. There was an instance when two turtles were going to be killed for a wedding dinner. On receiving an alert, Pugalarasan along with the Marine Police conducted a rescue operation and saved the turtles. Later they were released into the ocean.

But today things have changed and thanks to the strong network, whenever a turtle, dolphin or whale is stranded, fishermen inform Pugal or the Tree Foundation office. “Whenever I get a call from the fishermen about a stranded turtle or dolphin, I immediately drive to the place in our ambulance with the stranding kit. I give first aid to the injured turtle and bring it to the rescue and rehabilitation centre,” adds Pugal.

Once the turtle is brought to the centre, it is inspected and the treatment is started. Pugalarasan himself has helped in the rehabilitation of more than 40 turtles.

“I have seen Pugal when he was in his early 20s. Since then he has been part of Tree Foundation’s ‘Save the turtles’ mission. He has also helped Tree Foundation expand its conservation to other states. Apart from the turtle conservation initiatives, he along with his STPF members carry out several clean-up programmes along the beaches to make people understand the problems of pollution,” says Dr. Supraja.

Pugalarasan received the prestigious Ocean award from the Boat International in 2017 for pursuing sustainable ways of fishing, protecting sea turtles and educating people about endangered marine species.

He hopes to have a small research vessel someday to study endangered marine life. “I want to share everything I learn about the ocean and marine life. I want people to understand that we must take care of the ocean and its rich marine life. People should also refrain from polluting the ocean with plastic, chemical waste and other trash,” adds Pugalarasan.

NRI spreads awareness on Swachh Bharat

“Tamil Nadu is the 29th state I’m visiting. I’ve been driving through the country for around 183 days and have covered 41,000 km,” says Sangeetha Sridhar, rattling off numbers when asked about her journey.

An NRI from UAE, Ms. Sangeetha, who originally hails from Coimbatore, has been driving through the country in her modified Tata Hexa for her initiative – ‘Clean India Trail’.

“I wished to commemorate the 100th birth anniversary of Sheikh Zayed Bin Sultan Al Nahyan, the founding father of the UAE and the 150th birth anniversary of Mahatma Gandhi and undertake this trip as a goodwill journey. Gandhiji always dreamt of a clean and safe India for women and I planned this trip systematically to show that this doesn’t have to be a faraway dream,” she says.

Ms. Sangeetha began her trip from Mumbai on August 12 and has been travelling solo since then, visiting over 290 cities. Her travels, she says, have taught her self-reliance and sustainability while allowing her to soak in different cultures and have engaging conversations with interesting people.

Sanitation audit

“Through this journey, I’ve been auditing the condition of sanitation facilities available and creating awareness about the Swachh Bharat Mission. I drive a vehicle that is made in India and only use products and technology that are home-grown,” she says. Her car is fitted with solar panels and the middle seat has been removed to ensure that she can sleep inside. “At night, I ensure that I find a safe place to park my vehicle – either inside the compound of a residential complex or a police station. I sleep inside the vehicle and use the public sanitation facilities available,” she says.

Ms. Sangeetha has also been engaging with nearly 59 signature industries across the States she has travelled through and has also visited various heritage sites. Collaborating with a start-up, she explains that all the information she collects are documented on an app in her phone. “For my audit of the sanitation facilities, the app provides me with a log and I also can record voice notes which will be location-tagged so that I can go back to them later,” she says.

With her website www.cleanindiatrail.com detailing her travels, Ms. Sangeetha says that the results of her audit will be handed over to the United Nations Sustainable Development Board and the Ministry of Tourism. “People everywhere have been extremely welcoming. For women who wish to travel and go on long solo road trips, it is extremely important to prepare physically and mentally. Plan your milestones clearly so that you know what it is that you want to see and it is imperative to study everything along your route,” she adds.

Fifty years on, aircraft wreck found

AircraftWreckCF24feb2019

Seahawk jet sank in 1964 off the Neelankarai coast in south Chennai

A team of scuba divers has stumbled upon the wreckage of a single-seater aircraft that sank in the 1960s off the Neelankarai coast in south Chennai.

Residents of the fishing hamlet recalled that they had rescued the pilot, who was pulled out by two men who caught his long tresses on that day.

“I was just 10 years old then and my father showed me the aircraft as we were returning home after fishing. I saw it from a distance and saw it sink into the water,” said Devadas Ganapathi, who is now 65. His son Chandru was one of the four divers who found the wreckage. The others were S.S.B. Aravind Tharunsri, master instructor, Professional Association of Diving Instructors in Australia, who led the diving expedition, and Thimoth and Arun.

A report in The Hindu on August 13, 1964, said that an aircraft mechanic of the Navy had taken the Seahawk jet fighter for a spin from the Meenambakkam airport at 7.15 a.m. without informing the control tower. After circling over the city, he returned to the airport but could not land and went for another round but later crashed into the sea.

Mr. Devadas said that the man was unconscious when he was dragged out of the water and, later when he regained consciousness, he gave ₹10 notes to four fishers who helped him.

Scuba diver Mr. Aravind said the wreckage found at a depth of 12 metres at a distance of 1.5 km was quite intact.

“One wing is under the sea bed and the other one tilted upwards at an angle. Fishermen kept telling us to help them with the object that cut their nets. And two days ago, we found this wreckage. We will not touch it since it is not allowed,” he said.

IIT-M research generates lasers from carrots

Carrots cooked in alcohol may soon be a popular source of lasers.

Chennai :

Carrots cooked in alcohol may soon be a popular source of lasers. Researchers from the Indian Institute of Technology-Madras (IIT-M) have demonstrated the possibility of generating laser in an eco-friendly way, by using carrots as a lasing material, according to a statement issued by the institute.
The laser, generated through this technique, has immense potential in the field of bio-imaging.

Currently, the most common lasing materials, such as Indium-Gallium-Arsenic and Gallium-Nitrates, are manufactured using toxic chemical processes which are harmful to the environment. The new technique that the researchers have come up with uses just minimally processed carrots.“We fondly call this kitchen laser,” exclaimed Sivarama Krishnan, one of the guides of the research.

The research was undertaken by a team comprising Prof C Vijayan, Assistant Professor Sivarama Krishnan, and Venkata Siva Gummaluri, a PhD research scholar, from the Physics department of IIT-M.
The discovery itself was a result of the after-work-hours fun experiment, said Sivarama Krishnan. “We were pumping light through various organic materials and found that carrots have lasing properties. For example, we also tried orange juice and tomato juice,” he said. What set the humble carrot apart was the optically active bio-pigment called carotenoids present in the vegetable.

Although the fluorescence quantum yield of carotenoids is much less, compared to standard organic laser dyes, the vibrational spectra can be obtained even with extremely low concentrations of carotenoids, said Sivarama Krishnan. “We could easily increase the concentration of caretenoids on the surface of the carrots, by simply cooking it in alcohol. Then we pump light through a slice of the surface to get laser,” he said.

While the traditional polymers used were toxic and non-biodegradable, there has been search for more eco-friendly fluorescent polymers. In this search, the team looked at biological molecules as probable lasing sources.

Speaking about the importance of this research, Vijayan said, “There is now a move towards development of green, sustainable materials for various applications, including in photonics. The need for green photonic technologies is obvious in the current times where sustainability, bio-compatibility and degradability are of paramount importance.”

Carrots, in addition to having carotenoids, also have cellulose fibres that contribute to multiple scattering of photons and resultant optical amplification for Raman random lasing. The demonstration uses a process, first discovered by CV Raman, who won the Nobel Prize for Physics in 1930.

The researchers plan to advance their research to make the material more commercially viable. Currently, this material has potential as it is natural, bio-compatible, safe to handle and highly reliable.

Yards to dream upon

QuiltFestival01CF30jan2019

From portraits to Christmas patterns, the recently-concluded International Quilt Show showcased creative works of various sizes, shades and nationalities

Jim Morrison strikes a pose with his guitar as disco lights twinkle overhead. Then there are glasses of martini — shaken not stirred — dancing peacocks, cobbled stone paths and landscapes… all on quilts. The recently-concluded International Quilt Show, part of India Quilt Festival 2019 (organised by India Quilt Foundation), displayed patterns that ranged from creative and dramatic to quirky.

“This is the first time this event is being organised in India,” says Tina Katwal, who started India Quilt Foundation along with Deepa Vasudevan and Varsha Sundararajan in January 2018. The event was divided into two sections: competition and exhibition. The competition featured around 290 quilts. With its dizzying colours, varied themes and intricate work, the displays made sure the attendees had their phone cameras out the whole time. The lure of the quilts also ensured heavy traffic outside Sri Sankara Hall, the venue, as people came in droves to witness works of art.

The exhibition section had around 70 quilts, some on loan from countries such as the US, Hungary, Guatemala, Korea, Kuwait, UAE and Scotland.

QuiltFestival02CF30jan2019

“India has a large number of talented quilters. While quilting festivals happen the world over, we wondered why it hadn’t been organised here before. We have an online community called Desi Quilters. They seemed excited about the idea of a quilt show. And that’s how it started,” says Tina, who owns a quilt store called The Square Inch.

All about talent

Chitra Mandanna can hardly stop smiling. Of her six exhibited works, four have won her awards. “These include Best of Show and Judges’ Choice in the Art category, and a first prize and an honorary mention in the Theme category,” says Chitra.

QuiltFestival03CF30jan2019

A striking portrait of her uncle, made using cheesecloth and denim, stands out. “It took me a month to create this. Working with cheesecloth can be challenging,” says the 42-year-old, adding, “It took me seven months to complete all six quilts. I’ve used techniques such as beading, fabric manipulation, upcycling, confetti quilting…” Only after she lists the different techniques do we realise that there is so much more to quilting than just stitching together layers of fabric, usually saris.

The show also had entries by children, their quilts brimming with things that occupy their thoughts — cupcakes, ice cream sundaes and ice lollies. Ten-year-old S Ritika’s quilt is just as petite as her. The 26X40 inch quilt features a patchwork of chubby yellow, green, orange, pink and brown birds against a black background. “My mother introduced me to quilting. We have two machines at home and sew together,” says Ritika, who took two weeks to complete her quilt.

What also stands out is a hot pink quilt, with rectangular bars in sea green, brown, tan and shades of pink, created using patchwork and machine quilting techniques. Something that would look great as a sari. People around fondly refer to it as the “muttai pink delight”.

Monochrome on Fabric

“It’s actually a throw,” says Kamala Murali, its 29-year-old creator. “I am a textile designer and use a lot of quilts in my work,” she says, adding, “My grandmother has always collected quilts and since there is something so comforting about quilts, I gravitate towards it.” Kamala is also launching her own textile label titled Kambli, which means quilt in Tamil (nothing to do with Vinod Kambli, the cricketer!).

Quilting is no longer a hobby of the older generations. “I’ve noticed a lot of young people taking to it. I think it’s because they get a large surface to express what they want to say,” says Kamala.

Transform old clothes, wedding saris into heirloom pieces

TinaKatwalCF12jan2019

Wrapped in memories: Tina Katwal’s Memory Quilts transforms fabrics

Old baby clothes, wedding dresses or saris you bought for a particular event, all of these may have at least one thing in common: they are of no use anymore. Yet they are objects of such fond memories that one gets reluctant when it comes to disposing them.

Tina Katwal, founder of The Square Inch, has the perfect solution for you. Her new venture, The Memory Quilts, is all about preserving memories. Give her your baby clothes and she will transform them into a charming quilt, and even add a batting of cotton in between so you can snuggle with it.

Celebrating The Square Inch’s fifth anniversary, Tina talks about her early days as a quilt enthusiast. “For me it was a case of playing with scraps from clothes. When I was younger, I used to make my own clothes. Then I started playing around with scraps and turning them into a quilt,” says Tina. Eschewing the more traditional notions associated with the quilt, Tina has transformed it into a symbol of both beauty and utility, bringing out its latent artistic value.

“We have made quilts out of a child’s first year clothes; we have also made quilts for a child graduating out of school with his or her school uniform and sports’ T-shirts. These memory quilts are a great way to preserve and cherish memories and also document events in a person’s life,” says Tina, adding that customers even request her to make quilts in memory of others.

Memory Quilts also uses a range of different materials and fabrics. She has turned ponnadai (shawls) and even wedding saris into quilts.

“We can make them in any style as per the client’s request. They can be whimsical and fun, minimalist, subtle and elegant, or even bold and graphic. We can make it to go with the décor of the room or even the general mood of the house. We try to capture the personality of the person it is meant for,” she adds.

Talking of what inspires her, she says, “A bulk of tailor produce and worn out clothes go to waste as scraps. By making quilts, we are also reducing the amount of waste that goes to a landfill and encouraging sustainable practices all across the textile community.” The financial savings don’t hurt too, and Tina laughs about this ulterior objective.

“Not a single scrap of cloth is wasted here. Everything is upcycled or reused. That is our little contribution,” says Tina.

Till date, Tina has converted about 30 saris and hundreds of baby clothes into memorable quilts, giving people an opportunity to go to bed cocooned in fond memories.
