NATIONAL: ARCHITECTURE & DESIGN: Balkrishna Vithaldas Doshi (1927-2023) | Pioneer of Indian Modernist Architecture

Indian architect BV Doshi has passed away, at the age of 95. Trained under Le Corbusier, he was the only Indian to have been awarded the Pritzker Architecture Prize for designing IIM, Bengaluru.

One of the most distinguished Indian minds in the world of architecture, BV Doshi, passed away at the age of 95 on Tuesday. leaving behind a tall legacy and an irreplaceable void in the world’s design community.

BV or Balkrishna Vithaldas, won the gold medal awarded by the Royal Institute of British Architects in 2022, joining a select league of international names like Le Corbuiser, Louis I Kahn and Edwin Maxwell Fry.

A Padma Bhushan awardee, Doshi was known for designing the buildings of the Ahmedabad-based Centre for Environment and Planning Technology (CEPT) and Mahatma Gandhi Labour Institute.  His style of architecture — an amalgam of European modernist, brutalist architecture with Indian sensibilities — won many hearts.

Shiv Dutt Sharma (93), a contemporary of Doshi who had worked on the Chandigarh project with Corbusier, describes Doshi as “hospitable, amiable, simple and incredibly humble,” adding “He was a dear friend.”

In October last year, when this correspondent reached out to Doshi, his granddaughter Khushnu Panthaki-Hoof, principal architect, Studio Sangath, said that he was not talking to many journalists and was still recovering from a bout of COVID-19, which he had two months ago. But on learning that the article was intended to highlight Corbusier’s legacy, he made an exception. “I consider him my guru,” he had said at that time.

Apart from designing one of the finest buildings in Ahmedabad, Doshi also created designs for low-cost housing. His 1982 project, Aranya Low Cost Housing in Indore won him the 6th Aga Khan Award for Architecture. In another example of the international recognition of his works, Doshi was awarded France’s highest honour for the arts, the Officer of the Order of Arts and Letters, in 2011.

He graduated from the Sir JJ School of Architecture in Mumbai in 1950 and left for Europe soon after, beginning his journey in architecture with Corbusier in Paris between 1951 and 1954. On returning to India, he worked for Corbusier in Ahmedabad.

The celebrated architect authored several books on art and architecture, including Paths Uncharted (2011), Balkrishna Doshi: Writings on Architecture and Identity (2019), and Balkrishna Doshi: Architecture for the People (2019). Meanwhile, international architects ended up writing books on Doshi. This included William J R Curtis’s book Balkrishna Doshi: An Architecture for India, released in 2014.

In his book Paths Uncharted, former Chief Architect of Chandigarh, Sumit Kaur, points to an excerpt where Doshi wrote: “Frankly, at this stage in life I even hesitate in calling myself an architect because the more I think about what Architecture is, the less I feel I know about its true calling. Every time I felt I have mastered it, each new completed project has made me aware of how much more there is to Architecture. As a result I increasingly see myself more as a person seeking my destiny rather than just being an architect planner or such.”

A statement issued by his family said the cremation will take place at 2:30 pm at Thaltej Crematorium. The message read: “No one loved life more than him, ‘ Anand Karo’ – Celebrate Life, as he would always say. He had so many people that he loved dearly and who loved him back. He will leave for his onward journey from our residence Kamala House.”

B.V. Doshi passed away Tuesday, January 24th, 2023

NATIONAL: SCIENCE & TECHNOLOGY: JNCASR Scientists Develop Brain-like Computing with Industry Compatible Nitride Semiconductors

They used scandium nitride (ScN) to develop a device mimicking a synapse that controls the signal transmission as well as remembers the signal.

A team of scientists from the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have used scandium nitride (ScN) and Complementary Metal-Oxide-Semiconductor (CMOS) compatibility to develop brain-like computing.

This invention can provide a new material for stable, CMOS-compatible optoelectronic synaptic functionalities at a relatively lower energy cost and also potential to be translated into an industrial product.

According to the Department of Science and Technology, the JNCASR team led by Dheemahi Rao who were working on nitride-based materials used their background for developing hardware for neuromorphic computing. They used ScN to develop a device mimicking a synapse that controls the signal transmission as well as remembers the signal.

“The JNCASR team demonstrates an artificial optoelectronic synapse with ScN thin films that can mimic synaptic functionalities like short-term memory, long-term memory, the transition from short-term to long-term memory, learning–forgetting, frequency selective optical filtering, frequency-dependent potentiation and depression, Hebbian learning, and logic-gate operations,” states the department.

Compared to the existing materials used to demonstrate optoelectronic synapse, ScN is more stable, CMOS compatible, and can be seamlessly integrated with existing Si technology. It can act as a platform for both excitatory and inhibitory functions. The industrial processing techniques of ScN are similar to the existing semiconductor fabrication infrastructure. Response to the optical stimuli also has the advantage of possible integration with photonic circuits known for higher speed and broader bandwidth than electronic circuits.

“Our work enables neuromorphic computing research with a stable, scalable, and CMOS-compatible III-nitride semiconductor that exhibits both excitatory and inhibitory synaptic functionalities. Unlike the previous works on all-electronic synapse, our work shows an optoelectronic synapse with a large bandwidth, reduced RC delays, and low power consumption,”said Dr. Bivas Saha, Assistant Professor, JNCASR.

Apart from JNCASR, researchers from the University of Sydney (Dr. Magnus Garbrecht and Dr. Asha I. K. Pillai) also participated in this study published recently in the scientific journal Advanced Electronic Materials.

INTERNATIONAL: FOSSILS DISCOVERY: Dinosaur Nest Cluster with 256  eggs found in Narmada Valley, Madhya Pradesh

While dinosaur nests and eggs having been found in the past, too, this recent find raised the possibility of the Narmada Valley having been a fertile hatchery location for dinosaurs millions of years.

A rare discovery of 92 closely located dinosaur nests and 256 fossilised eggs of herbivorous Titanosaurs (one of the largest known dinosaurs) has been made by a team of palaeontologists in Dhar district, which is part of the Narmada Valley in Madhya Pradesh.

While dinosaur nests and eggs having been found in the past, too, by other palaeontologists in the Jabalpur region of MP and Balasinor in Gujarat, this recent find raised the possibility of the Narmada Valley having been a fertile hatchery location for dinosaurs millions of years ago.

The field research was carried out by a team of palaeontologists from Delhi University, Indian Institute of Science Education and Research, Mohanpur-Kolkata and Bhopal in many villages of Bagh and Kukshi areas of Dhar district between 2017 and 2020.

A paper on their research by Harsha Dhiman, Vishal Verma, G V R Prasad and others was recently published in the PLOS ONE research journal. “A major inference from the three years of research is that the nests and eggs found in the villages of Dhar district date back 66 million years ago.

It’s quite possible that the Titanosaurs either just came to lay the eggs in this area of Narmada Valley or the eggs were also hatched there. The eggs found by us show evidence of hatching as well as not having been hatched,” Dhiman, the lead researcher told this newspaper on Saturday. “Since only nests and eggs and not bones have been found, we need to perform micro CT scan for further research,” Dhiman added.

Egg Diameter around 15-17 cm
The nests found in the Narmada valley were close to each other, which is generally not the case. These nests had eggs which ranged between 15 cm and 17 cm in diameter. “Each nest had between one and 20 eggs,” Dhiman said

NATIONAL: DEFENCE SERVICES: Woman Naval Air Operations Officer Lt Commander Disha Amrith to Lead Indian Navy’s Contingent at 2023 Republic Day Parade

Navy officials said three women and five men Agniveers will also participate in the parade at Kartavya Path.

Lt Commander Disha Amrith, a woman naval air operations official posted at a strategic base, will lead the Indian Navy’s Republic Day contingent of 144 young sailors and its tableau will showcase the ‘Nari Shakti’ in force.

Navy officials said three women and five men Agniveers will also participate in the parade at Kartavya Path.

Besides Amrith, another woman officer — Sub Lt Valli Meena S — will be among the three platoon commanders of the naval contingent.

A Bachelor of Engineering in Computer Science from BMS College of Engineering in Karnataka, 29-year-old Amrith was part of the National Cadet Corps’s Republic Day team in 2008 and harboured the dream of being part of the marching contingents of one of the three services at the celebrations in Delhi.

“Since 2008, I was nurturing this dream of being part of the Republic Day contingent of the armed forces. It is an amazing opportunity that the Indian Navy has given me (to lead the naval contingent),” she said.

The officer, who hails from Mangaluru, got into the Navy in 2016 and has been posted at a key naval facility in the Andaman and Nicobar islands after completing her training in 2017.

“I am an aviator for Dornier aircraft and have been carrying out sorties in the plane,” she told PTI.

Last month, Navy Chief Admiral R Hari Kumar said the Navy is looking at opening all its  branches for women from 2023.

Sharing her experience, Amrith said she always wanted to be part of the armed forces and it was partly inspired by her parents as well.

“My father also wanted to be part of the services but could not. I am proud to be part of the Navy and will continue to serve the Navy with full zeal and dedication,” she said.

Asked about the challenges that women face in the forces, Amrith said, “I became stronger physically, emotionally and I am now more self-driven.” The renowned brass band of the Indian Navy of 80 musicians will be led by M Antony Raj, playing the Indian Navy Song ‘Jai Bharti’.

The theme of the naval tableau would be ‘Indian Navy — Combat Ready, Credible, Cohesive and Future Proof,’ said Vice Admiral Suraj Berry,  the Controller Personnel Services (CPS).

He said the tableau is designed with an aim to showcase the multi-dimensional capabilities of the Indian Navy as well as highlight key indigenously designed and built platforms.

“The tableau also aims to highlight ‘Nari Shakti’ in the Indian Navy,” he told reporters.

The forward part of the tableau will showcase a woman aircrew of Dornier aircraft (flying overhead), highlighting the all-women crew of a surveillance sortie undertaken last year.

The main section of the tableau will illustrate the ‘Make in India’ initiatives of the Navy and model of the new indigenous Nilgiri class ship with a Dhruv helicopter deploying marine commandos will take the centre-stage.  On the sides of the main section, cut out models of indigenous Kalvari Class submarine will be depicted.

In the rear section of the tableau, three models of autonomous unmanned systems being developed indigenously under IDEX-Sprint Challenge will be displayed.

The Indian Navy aims to induct at least 75 technology/product as part of Azadi Ka Amrit Mahotsav.

The sprint initiative was launched by Prime Minister Narendra Modi during the Naval Innovation and Indignation Organisation Seminar in July last year.

These products are being developed under the innovation for defence excellence scheme of the Ministry of Defence and Technology Development Acceleration Cell of Indian Navy, the official said.
