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.

Lateral upgrade to ailing annihilation

Lateral upgrade to ailing annihilation

Being the first person from the private sector to be appointed as chairperson of Securities and Exchange Board of India (SEBI) as part of the government’s lateral initiative, Madhabi Puri Buch also holds the honour of being the first woman to hold the top post as capital market regulator.

But the laurels that the former private sector banker enjoyed in her earlier stint with ICICI Bank, was marred with allegations that she and her husband were having a stake in offshore entities, which were used to artificially inflate shares of Adani group companies.

Terming the allegation as `character assassination, Buch clarified that all disclosures have already been furnished and the fund in question did not invest in any securities involving the Adani group.

When it rains, it pours. This allegation was subsequently followed by Congress Party allegation that Buch had received salary and post-retirement benefits from ICICI Bank after she quit the private sector bank.

In its clarification to the stock exchanges, ICICI Bank asserted that the payments made to Buch were purely retirement benefits after her exit from the bank and they were neither salary nor employee stock options.

Prior to these allegations, Buch tenure at SEBI was all about bringing in quick reforms on operational issues by changing the format of consultation paper to bring in larger responses digitally. Being data savvy, the rationale of her decisions were democratic based on big data analysis derived from the responses received to the consultation papers.

Further she bifurcated the duties of the SEBI staff between operations and enforcement, which were done by the same persons earlier. Having worked for the private sector in the capital market domain space, Buch had a better understanding of the subject compared to officers from the administrative service in the past that reflected even in her orders as a whole-time director at SEBI before becoming the chairperson. As a whole time director at SEBI, her orders on adjudication issues were more directional to the capital market space, according to experts in the compliance space. She was also quick to revamp the old provisions of the 90s at SEBI.

Being tech and data savvy, Buch enhanced regulatory surveillance and detection of market manipulation, insider trading and fraud while also emphasizing on strengthening corporate governance by introducing stricter rules for independent directors and enhancing disclosures for related-party transactions.

To put in perspective, the annual report of the capital market regulator in the just concluded financial year revealed that the number of investigations related to insider trading jumped to 175 in 2023-24 from 85 in the preceding year while probes related to front running jumped over three times to 83 from 24 in the preceding year.

Transparency in mutual funds by implementing measures to protect retail investors along with tightening norms for initial public offers, particularly in the SME platforms were some of her other positive initiatives including confirmation of denial of any market rumours within 24 hours for the top 100 listed companies which will be extended to top 250 companies from December 1. However increased transparency and compliance with tightening regulations led to increased operational costs for the market participants and hence faced resistance from certain quarters. Born in 1966, Buch completed her primary education in Mumbai and graduated with specialization in Mathematics from Delhi and later obtained a management degree from Indian Institute of Management, Ahmedabad. In between, she got engaged to Dhawal Buch, a director at a consumer goods multinational at the age of eighteen and got married at the age of 21.

Besides ICICI Bank, Buch also worked as a lecturer at a college in England, worked at Greater Pacific Capital in Singapore and ICICI Securities as its CEO. She also worked as executive director on several private sector companies and as a consultant for New Development Bank (Brics Bank).

What now remains to be seen, is whether Buch, who survived the 26/11 terror attack when she along with her husband, was attending a meeting at Taj, be able to overcome the current ordeal. Keeping fingers crossed for the times to come.
