Proud moment for Shivaji University researchers

Indian patent for portable sound absorption testing device Kolhapur: Researchers from Shivaji University, Kolhapur, have developed a portable sound absorption testing device that can scientifically assess whether an installed sound system and its acoustic treatment are functioning effectively. The innovation has been granted an Indian patent, marking a first-of-its-kind development in this field, the university said on Thursday. The patented device, named the Portable Sound Absorption Tester, has been developed by senior chemist Dr Kalyanrao Garadkar of Shivaji University, along with Dr Sandeep Sable and Dr Rohant Dhabbe of Jaysingpur College, and Dr Chandrala Jatkar of the D K T E Society’s Textile and Engineering Institute, Ichalkaranji. The device is designed to test the sound absorption capacity of professional acoustic systems used in recording studios, theatres, auditoriums and soundproof chambers. Until now, the effectiveness of such sound-absorbing installations has largely been assessed through experience and trial-and-error after installation. The newly developed portable tester allows for immediate and scientific evaluation of sound absorption performance once the system is installed. Sound-absorbing sheets and panels are widely used in theatres, studios and vocal recording rooms to absorb echo around microphones and create a controlled acoustic environment, enabling cleaner and more professional audio output. The new device can be used to evaluate a wide range of absorbers, including perforated foam, fibre, fabric, membranes, panels and resonant absorbers, helping improve the quality and effectiveness of acoustic materials. Explaining the working of the device, Dr Garadkar said that the human audible frequency range extends from 20 Hz to 20 kHz. The device generates sound waves within this spectrum and projects them onto the acoustic material under test. The sound waves that are not absorbed are detected by a microphone and displayed on the screen in the form of current or voltage readings. This enables users to instantly determine whether the sound absorption system is functioning as intended and make corrective interventions if required. The researchers said the device would also be useful for those engaged in acoustic fabrication and sound absorption research. Apart from being portable and easy to transport, the device is also cost-effective, making it suitable for field applications. The team expressed confidence that it would prove highly useful in the sound system testing sector. Shivaji University’s in-charge Vice-Chancellor Dr Suresh Gosavi and in-charge Pro Vice-Chancellor Dr Jyoti Jadhav congratulated the research team on securing the patent.

The Diplomat at the Heart of the Indo-Canadian Schism

Updated: Oct 30, 2024

Sanjay Kumar Verma

The story of Sanjay Kumar Verma, hitherto India’s high commissioner to Canada until his abrupt recall, reveals more than a tale of a diplomat caught in a crossfire of geopolitical tension. His journey embodies the complex, often dangerous balance Indian diplomats must maintain as representatives of the world’s largest democracy.


As Indo-Canadian relations hit rock bottom, Verma’s story captures an extraordinary chapter: an attack by extremists in Alberta, accusations of involvement in a murder case, and a rapidly souring relationship between two nations that once shared a vision for mutual progress.


Born in 1965, Verma had a brilliant academic record, overcoming the challenges of a modest background. He graduated from Patna University before pursuing a postgraduate degree in Physics at IIT Delhi. His diplomatic career began in the late eighties, when he joined the Indian Foreign Service. Over the years, he would gain experience in some of the world’s most culturally complex environments. Starting in Hong Kong, he later served in embassies across China, Vietnam, and Turkiye before becoming the Consul General in Milan and, subsequently, India’s Ambassador to Sudan. His ascent through the ranks continued, with stints in Tokyo and the Marshall Islands, before culminating in his role as High Commissioner to Canada.


In Canada, however, Verma found himself on unexpectedly turbulent terrain. India and Canada have long shared a diplomatic relationship that has oscillated between cooperation and contention. Historically, both countries found common ground in their shared status as former British colonies and members of the Commonwealth. The bilateral ties deepened during the early years of Indian independence, as Canada extended development aid to India and welcomed Indian immigrants, who went on to become a vital part of the Canadian multicultural fabric. However, relations strained in the 1980s as Canada became a hub for Sikh separatist movements, especially the Khalistan movement. This tension escalated with the tragic 1985 Air India Flight 182 bombing, which killed 329 people and cast a lasting shadow over bilateral relations.


Indian leaders have voiced frustration over Canada’s perceived leniency toward secessionist groups. Diplomatic exchanges, including those between Verma and Canadian officials, highlight unresolved grievances and new tensions on both sides.


Just before his recall, Verma recounted a harrowing experience of being surrounded and nearly attacked by a group of Khalistani extremists wielding what he identified as a sword and which was distinctly different from the kirpan, a Sikh religious symbol. The ambush took place outside an event meant to foster cultural and business ties between Indians and Canadians. “It came to within inches of my body,” he recalled in a recent interview, describing how local police pushed the crowd back only after they had encircled him.

His wife was by his side, and their alarm was shared by the small contingent of security officers who, perhaps like Verma, had underestimated the reach of hostility.


Verma’s tenure in Canada was marked by his increasingly vocal stance on the plight of Indian students—a population exceeding 300,000—caught, he claimed, in the allure of anti-India extremism caused by economic hardship and ideological manipulation.


His removal from Canada is underscored by Ottawa’s recent claims that Verma was linked to the investigation of Hardeep Singh Nijjar’s killing, a designated terrorist in India. Ottawa’s accusations, first articulated in a pointed speech by Canadian Prime Minister Justin Trudeau, suggested “credible allegations” of Indian involvement, further implicating Verma. India responded swiftly, rejecting the claims as “absurd” and “motivated,” a sentiment echoed by Verma, who dismissed the allegations as a “political farce.”


Despite these exchanges, Verma’s intentions in Canada remained rooted, as he put it, in preserving diplomatic dialogue. But the recall laid bare India’s contention that Canada has provided undue space to anti-India elements under the guise of freedom of speech and assembly—a freedom that, in Verma’s experience, came too close for comfort.


As he returned to Delhi, Verma appeared keenly aware that the bridge between Ottawa and New Delhi would be a difficult one to rebuild. In a final appeal, he expressed a hope that both nations could “restore” a once-promising relationship.
