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.

Shinde says he made the common man a superman

THE CM PRESENTS A ‘REPORT CARD’ OF HIS GOVERNMENT’S ACHIEVEMENTS IN LAST TWO AND HALF YEARS

Mumbai: Chief Minister Eknath Shinde has launched a scathing attack on the opposition Maharashtra Vikas Aghadi (MVA) accusing them of having an anti-development vision. This bold claim comes ahead of the Assembly polls, where Shinde’s government is seeking re-election. 


Flanked by Deputy CMs Devendra Fadnavis and Ajit Pawar, as well as Union Minister Ramdas Athawale, Shinde presented a “report card” highlighting his government’s achievements over the past two years. The report card contrasts the work done by the current Mahayuti government with that of the previous MVA dispensation, showcasing the ruling alliance’s accomplishments


Shinde presented a united front with his Deputies at a joint press conference, a day after the Election Commission announced the state poll schedule. The Assembly polls are scheduled for November 20, with votes being counted on November 23. 


Fadnavis said the seat-sharing discussions among the ruling allies in Maharashtra, consisting of the BJP, Shiv Sena, and other parties, are nearing completion. The Mahayuti allies presented a “report card” of the government’s work in the last two years, as Shinde, Fadnavis and Pawar accused the opposition of creating a “fake narrative”


The “report card” compared the work done by the previous MVA dispensation and the current Mahayuti government.


Shinde highlighted his government’s achievements over the past two years. The “report card” boasts of significant development projects, including the completion of the high-speed Mumbai-Ahmedabad railway and the Metro project in Mumbai, which were allegedly stalled by the previous MVA government. Additionally, the Mahayuti government claims to have made substantial progress in boosting Maharashtra’s economy, aiming to make it a $1.5 trillion economy by 2047.


“The opposition MVA were working with an anti-development vision, claiming they halted crucial development projects during their tenure. Specifically, Shinde cited the high-speed Mumbai-Ahmedabad railway (bullet train) project and the Metro project in Mumbai, which he said were stalled due to the previous MVA government’s opposition,” the CM said, accusing the opposition of defaming Maharashtra.


Without naming his predecessor Uddhav Thackeray or his son and former minister Aaditya Thackeray, Shinde said the cost of Metro project in Mumbai rose by Rs 14,000 crore as Aarey car shed was opposed due to “bal hatta” (insistence of a child) and arrogance.


All development works, like the high speed Mumbai-Ahmedabad railway (bullet train) project, were stopped by the previous MVA government, he said.


On seat-sharing among the Mahayuti partners, Fadnavis said it (discussion) has reached the final stages, but added the formula cannot be revealed now. It will be revealed only after the talks are completed, he added.


Pawar, who is also the state finance minister, said the opposition was caught off guard by the overwhelming popularity of the ‘Mukhyamantri Ladki Bahin Yojana’, a flagship program launched by the Maharashtra government to provide financial assistance to women.” When the scheme was announced, the initial allocation for the scheme was Rs 10,000 crore, but it was raised to Rs 45,000 crore, he said.


Pawar said 2.5 crore eligible women have received Rs 7,500 each in five months since the scheme was launched.
