India’s first underwater (subaqueous tunnel) rail system and the world’s highest railway arch bridge, built across the Chenab Bridge in J&K has sparked curiosity among the public.

The ongoing Indian International Trade Fair (IITF) at Delhi’s Pragati Maidan, witnessed the Ministry of Railway setting up a sprawling pavilion showcasing all of the railway’s technical advancements on the ironic rail bridge over Chenab and water tunnels. The ministry has highlighted many first-of-its-kind and marvellous facets of Indian Railways, which are attracting crowds of curious visitors.

Exhibiting prototypes of various mega projects, the railway has also exhibited the prototype of the re-developed ‘Ayodhya city railway station, of which the designs are inspired by the Ram Janambhoomi temple’s design.

Sharing details with the media on Tuesday, the Ministry of Railway claimed that various themes have been exhibited with their technological and structural advances through photos, translates and models.

“The model showing the world’s highest rail bridge on Chenab and India’s first underwater rail system, which is being built as part of the East-West Metro corridor of the metro railway in Kolkata, has been drawing huge crowds of curious visitors”, said a senior railway official.

The sports gallery exhibits awards won by the railway teams and an earmarked space showing the historic march of Indian Railways from the old days to the days of manufacturing and running high-speed Vande Bharat trains to the working of bullet trains, has also gathered a lot of onlookers.

“Another most interesting part of the railway’s pavilion is that it has made side walls based on the theme of ‘Azadi Ki Rail Gadi aur Station’ which throws light on the strong connection between freedom struggle and association of railways”, said a railway official. They also added adding that the redeveloped Ayodhya railway station with the design inspired by Lord Rama Janambhoomi temple has proved to be one of the huge crowd-pulling parts at the pavilion.

Besides this, the Ministry of Railways has also displayed the prototypes of its mega Sabarmati multimodal passenger hub and the casting yard of India’s first Bullet train project as part of the Mumbai-Ahmadabad high-speed rail corridor.

Not only this but the country’s first-of-its-kind solar plant at Bina in MP that generates solar power directly to 25 kV overhead electrical equipment to haul trains was displayed apart from the country’s first indigenous semi-high speed Vande Bharat train.

To make the visit of people at the railway pavilion memorable, the Ministry has created a special selfie booth titled ‘I am at Railway station’ for people to click pictures.

NATIONAL: SCIENCE & TECHNOLOGY / DEFENCE / AEROSPACE: ISRO’s Vikram Sarabhai Space Centre carries out Parachute Airdrop test of Gaganyaan Human Spaceflight programme

The Gaganyaan deceleration system consists of three main parachutes, besides the smaller ACS, pilot, and drogue parachutes, to reduce the speed of the crew module to safe levels during its landing.

ISRO’s Vikram Sarabhai Space Centre has conducted the Integrated Main Parachute Airdrop Test (IMAT) of its crew module deceleration system for the much-awaited maiden Gaganyaan human spaceflight programme at the Babina Field Fire Range (BFFR) in Jhansi district of Uttar Pradesh.

The IMAT conducted on Friday marks a significant milestone toward realising the nation’s ambitious Gaganyaan project, the Indian Space Research Organisation (ISRO) said in a statement.

The Gaganyaan deceleration system consists of three main parachutes, besides the smaller ACS, pilot, and drogue parachutes, to reduce the speed of the crew module to safe levels during its landing, the space agency said.

Two of the three main chutes are sufficient to land the astronauts on earth, and the third is redundant, ISRO said adding that the IMAT test simulated the case when one main chute failed to open.

The IMAT test is the first in a series of integrated parachute airdrop tests planned to simulate different failure conditions of the parachute system before it is deemed qualified to be used in the first human spaceflight mission.

In this test, a five-tonne dummy mass, equivalent to the crew module mass, was taken to an altitude of 2.5 kilometres and dropped using the Indian Air Force’s IL-76 aircraft. Two small pyro-based mortar-deployed pilot parachutes then pulled the main parachutes.

The main parachute sizes were initially restricted to a smaller area to reduce the opening shock. After seven seconds, the pyro-based reefing line cutters cut the area restricting line, allowing the parachutes to inflate fully.

“The fully inflated main parachutes reduced the payload speed to a safe landing speed. The entire sequence lasted about 2-3 minutes as the scientists watched the different phases of the deployment sequence unfold with bated breath. There was loud cheer and applause as the payload mass landed softly on the ground and the gigantic parachutes collapsed,” the statement read.

The design and development of the parachute-based deceleration system is a joint venture of ISRO and the Defence Research and Development Organisation (DRDO).

“The overall system design, analytical simulations of parachute deployment and crew module descent under various conditions, the design and development of ordnance devices for parachute extraction and ejection, assembly, mechanical and electrical integration of deceleration system, it’s instrumentation and avionics for conducting this drop tests are done at ISRO’s leading Research and Development centre, Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram,” the space agency explained.

Senior ISRO and DRDO scientists and airforce officers were present when the crucial test was done.

“Besides proving the calibre of the scientists of ISRO and DRDO, the test also demonstrated the active coordination between the country’s premier agencies, namely ISRO, DRDO, the Indian Air Force, and the Indian Army,” ISRO said quoting a senior official.

The competition took into account real-life issues and the three winning teams are Sputnik Brain, Udaan and Alpha Monitor who get a total grant of Rs 1 crore and a six-month incubation by the Foundation for Innovation & Technology Transfer, IIT Delhi, to strengthen their prototypes, and seek real-world consumer validation for their products and services.

There was no first, second or third place, for all the three teams are winners and they have come up with equally good solutions to real-life problems. In June, as part of its Solve for Tomorrow programme, Samsung invited 16-22 year-olds in India to come up with innovative ideas in the areas of education, environment, healthcare and agriculture, the priority UN Sustainable Development Goals for India. A record 18,000 plus registrations were received in the inaugural edition.

Let’s look at the three winning entries. Sputnik Brain’s Shankar Srinivasan is working on a wearable device that will help reduce stress by “productising pleasure through safe brain modulation”. His safe brain modulation wearable device for mental health transmits waves within the FDA’s limit of frequency, intensity, and Pulse Repetition Period to mood centres in the brain. Considering stress causes high blood pressure, hypertension and a host of other issues, the 22-year-old decided to work on an innovation to reduce stress.

The trio of Prisha Dubey, Anupriya Nayak and Vanalika Konwar of Udaan are from Port Blair and Delhi and they have developed eco-friendly, affordable and washable sanitary pads using shredded sugarcane bagasse. The all-girls team wants to solve the social stigma around menstruation and reach out to underprivileged and rural women with their product.

Hemesh Chadalavada of Alpha Monitor from Hyderabad has developed a smart wristband to monitor Alzheimer’s patients and alert their caregivers about changes in their behaviour. The 16-year-old’s device monitors the patient’s health parameters, such as pulse and blood pressure and the caregiver and doctor are automatically alerted if the patient gets out of bed and starts wandering.

 “All the young Solvers are the future of India. They have the potential to change India and the world,” said Ken Kang, president and CEO, Samsung Southwest Asia. “The jury found it extremely tough to choose the top three winners as all the participants had brilliant ideas. We are delighted to support them in their future journey to unlock their full potential and strengthen our vision of powering digital India,” said Partha Ghosh, head, corporate social responsibility and communications, Samsung Southwest Asia.

GLOBAL: INDIA APPLAUDED: Bali G20 Summit: WHO Chief Tedros Adhanom Ghebreyesus thanks Prime Minister Modi for Collaboration in Building a Global Traditional Health Centre to ensure ‘Health for All’

Centre, supported by an investment of $250 million from India, aims at harnessing the potential of traditional medicine from across the world.

WHO chief Tedros Adhanom Ghebreyesus on Tuesday thanked Prime Minister Narendra Modi for collaborating with the world health body on hosting and building the global traditional health centre.

Prime Minister Modi, World Health Organisation Director-General Ghebreyesus and Mauritius Prime Minister Pravind Jugnauth laid the foundation stone for the WHO Global Centre for Traditional Medicine (GCTM) in Gujarat’s Jamnagar city in April.

The centre, supported by an investment of USD 250 million from India, aims at harnessing the potential of traditional medicine from across the world through modern science and technology to improve the health of people and the planet, according to the WHO.

Taking to Twitter, Ghebreyesus, who is in Bali to attend the ongoing G20 summit, tweeted, “Thank you #India Prime Minister @narendramodi for your collaboration with @WHO on hosting and building the global traditional health centre. Together for #HealthForAll! #G20.”

Ghebreyesus also posted a picture of him with Prime Minister Modi at the G20 Summit in Bali.

According to WHO, around 80% of the world’s population is estimated to use traditional medicine. To date, 170 of the 194 WHO member states have reported the use of traditional medicine, and their governments have asked for WHO’s support in creating a body of reliable evidence and data on traditional medicine practices and products.

During his address at the G20 Summit, Ghebreyesus underlined that food and energy are fundamental to human life, and human health. The lack of either, or their over-consumption, can have severe consequences for health and economies.

“The heaviest price for the crises in food and energy security is paid in human health. My ask for the @g20org leaders is to ensure that measures to protect and promote health are central to the global response,” he added

INTERNATIONAL: PLANETARY SCIENCE: Dr. Arshia M Jacob, Winner of the prestigious ‘German Astronomical Society Award’

Dr Arshiya M Jacob is currently living the life of her dreams. Interested in science since childhood, she is now a research scholar at the iconic Max Planck Society in Germany. Moreover, she won the German Astronomical Society Award for the best research thesis.

Hailing from Maradu in Ernakulam district, Arshiya completed her B.Sc (Hons) in Physics from St. Stephen’s College, Delhi. In the second year, she was associated with the PSLV project at ISRO as part of her internship. This attracted her to astronomy.

After completing her degree in 2015, Arshia did her post-graduation at Bonn University in Germany. The thesis she submitted as part of the course impressed the director of the Max Planck Institute of Radio Astronomy. After that she got an opportunity to do research at the Max Planck Institute. Her research can be described, in simple terms, as the study of how clouds transform into stars.

Arshia studies matter and radiation in the galaxy. She also discovered some information about the chemical origin of the Milky Way. As part of the studies, Arshia Sofia also flew in the research plane.

Arsia’s research won the Otto Hahn Award, established by the Max Planck Society. The prestigious Otto Hahn Award is given to thirteen scientists who have made impressive research in the fields of physics and chemistry.

She gained the fame of this award when she won the award by the German Astronomical Society.

Dr. Arshia, who is currently pursuing a post-doctoral fellowship at John Hopkins University, Baltimore, United States, may return to Germany after completing his course. At Max Planck she could continue her research work with her own team of scientists.

Founded in 1948, the Max Planck Society has produced 23 Nobel Laureates till date. Swedish geneticist Svante Pabo, who won the Nobel Prize in Medicine this year, is part of the institute.

Research in science requires patience and dedication. Researchers should not be discouraged when results are negative or inconclusive. However, they have to work persistently to get the desired results that can significantly impact humanity.

The Stratospheric Observatory for Infrared Astronomy is a joint project of NASA and the German Aerospace Center. The Boeing 747 SP aircraft has a reflecting telescope that can be observed under infrared lighting. The plane flies in the stratosphere – the layer of atmosphere that surrounds the Earth at an altitude of 11-13 km. Ground-based telescopes cannot make observations in the infrared field because the Earth’s atmosphere and water particles block infrared rays.

The Sophia project, which started in 2010, ended in September this year.

GLOBAL: TRANSPORT INFRA-STRUCTURE / RANKING : India’s Metro Network is Currently World’s 5th Largest: Hardeep Puri . Poised to Overtake Japan and Korea as 3rd Largest.

Around 810 km of metro line are operational in 20 cities in the country while more than 980 km of metro network and RRTS is currently under construction in 27 cities, Union Minister for Housing and Urban Affairs Hardeep Puri said on Friday, adding India currently has the fifth-largest metro network in the world.

“India will soon overtake advanced economies such as Japan and South Korea to become the third-largest network. These developments will lead to a significant reduction of traffic congestion and the associated air quality and emissions concerns,” the Minister said.

Puri, and Kerala Chief Minister Pinarayi Vijayan on Friday jointly inaugurated the 15th Urban Mobility India (UMI) Conference and Expo 2022 in Kochi.

Acknowledging the incorporation of best practices/ learnings from other countries into Indian Urban Mobility Systems, Hardeep Puri said that we have been able to learn from the experience of other countries.

The metro lines that we are introducing today are the kind of systems which are incorporating the best practices from others.

Our process of indigenisation is going to contribute to also an experience wherein we will be able to share with other countries placed in the similar level of the developmental ladder, he added further.

The Minister expressed satisfaction for his association with transport and the evolution of metro systems and other transport systems over the period of five years.

The Minister congratulated the Kochi Metro for the innovative Kochi Water Metro project, which will connect 10 islands through 15 routes and will cater to more than 100,000 people daily across 78 km of network.

The Water Metro will also provide a cheaper and more sustainable alternative to daily commuters.

Inland water transport is inherently more energy efficient than road or rail transport, he said.

NATIONAL: DEFENCE / SCIENCE & TECHNOLOGY : India’s DRDO Tests for First Time its Phase Two BMD Interceptor AD-1,Long-Range Interceptor Missile

India on Wednesday conducted a critical test to validate and showcase its ballistic missile defence (BMD) capabilities to intercept long-range missiles, the defence ministry said.

The Defence Research and Development Organisation (DRDO) successfully tested for the first time a long-range interceptor missile, called AD-1, designed for both low exo-atmospheric and endo-atmospheric interception of ballistic missiles and fighter planes, officials familiar with the matter said.

Defence minister Rajnath Singh described the missile as a “unique type of interceptor” equipped with advanced technologies available only with a few countries.

India has made significant advances in developing endo-atmospheric and exo-atmospheric intercept systems to destroy incoming hostile missiles within and outside the atmospheric limits, respectively. The two systems have been integrated for a multi-layered defence against ballistic missiles, the officials said.

The phase-II BMD interceptor AD-1 missile with a “large kill altitude bracket” was tested from the APJ Abdul Kalam Island off the Odisha coast. “The flight test was carried out with participation of all BMD weapon system elements located at different geographical locations,” the ministry said in a statement.

India is pursuing its BMD programme in two phases – the first phase has been completed while the second is underway, the officials said. The second phase is for validating intercept systems in a new range category, they said.

The AD-1 missile is propelled by a two-stage solid motor and equipped with an indigenously-developed advanced control system, and navigation and guidance algorithm to precisely guide the vehicle to the target, the ministry said.

“During the flight test, all the sub-systems performed as per expectations and were validated by the data captured by a number of range sensors including radar, telemetry and electro-optical tracking stations deployed to capture the flight data.”

The defence minister said the new missile will further strengthen the country’s BMD capability to the next level, even as DRDO chief Samir V Kamat said the interceptor will provide immense operational flexibility to the users to engage different types of targets.

The integrated exo and endo-atmospheric systems offer a hit-to-kill probability of 99.8 per cent, as previously reported.

NATIONAL: HEALTH & MEDICAL SERVICES / RESEARCH / ARTIFICIAL INTELLIGENCE(AI) : IIT Guwahati develops AI model to Predict Bone Repair Outcomes after Surgery

Researchers at the Indian Institute of Technology (IIT), Guwahati have developed an Artificial Intelligence (AI) model to predict the healing of thigh bone fractures after surgery.

According to the team, the model can be used to assess the healing outcomes of different fracture fixation strategies so that an optimum strategy can be chosen for the patient depending on their personal physiologies and fracture type.

Using such precision models can reduce the healing time, and lighten the economic burden and pain for patients who need thigh fracture treatment, they said.

The results of the research have recently been published in open-source journal, “PLoS One”.

“AI has tremendous potential when it comes to understanding and predicting complex biological phenomena and hence, can play a big role in health sciences applications,” said Souptick Chanda, Assistant Professor, Department of Biosciences and Bioengineering, IIT Guwahati.

The research team has used a combination of Finite Element Analysis and the AI tool “Fuzzy Logic” to understand the healing process of fracture after various treatment methods.

Various bone growth parameters were used along with a rule-based simulation scheme for this purpose.

The study further examined the influence of different screw fixation mechanisms to compare the fracture healing efficacies of each process.

The predictions of healing made by the model agreed well with experimental observations, pointing to its reliability.

“Our simulation model can potentially help a surgeon choose the right implant or technique before a fracture treatment surgery. In addition to various biological and patient-specific parameters, the model can also account for different clinical phenomena, such as smoking, diabetes, etc. The model can also be adapted for veterinary fractures which are, physiologically and in various aspects, similar to those occurring in humans,” Chanda added.

The researchers plan to develop a software or app based on the algorithm that can be used in hospitals and other healthcare institutions as part of their fracture treatment protocols.

The team is presently collaborating with Dr Bhaskar Borgohain and his team of orthopaedists from the North Eastern Indira Gandhi Regional Institute of Health and Medical Sciences Hospital, Shillong, for animal studies to validate and fine-tune certain parameters.

“The research is useful because incidences of thigh bone and hip fractures have increased significantly due to the increasing geriatric population in the world. An estimated 2 lakh hip fractures occur every year in India alone, most of which require hospitalisation and trauma care. Treatment for hip fractures traditionally includes bone plates and rods to bridge the fracture site and promote bone healing,” said Pratik Nag, research scholar at IIT Guwahati.

“Fracture treatment methods are intuitively chosen by surgeons based on their experience, and there is no way of predicting the efficacy and success of the treatment method chosen. Our research will help increase the accuracy rate in decision-making in orthopaedics, thereby reducing the cost and disease burden associated with fracture recovery,” he added.
