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.

Sunetra Pawar’s Trial by Fire

The rise of the late Ajit Pawar’s wife will test whether patience and emotional control can succeed in one of India’s most abrasive political arenas.

When Sunetra Pawar, wife of Maharashtra’s late Deputy Chief Minister Ajit Pawar, stepped into active politics, the question that immediately followed her was direct and unavoidable: Can she handle politics? This question is being asked not just by opposition leaders or television panellists, but also by ordinary citizens trying to understand what her rise means for Maharashtra. Her entry into high-level politics did not follow the traditional route of years of public campaigning or electoral grooming. Instead, it came at a moment shaped by personal loss and political uncertainty. This has made her journey both sensitive and significant. For some, she represents continuity in a powerful political legacy. For others, she symbolises a test case for leadership built on restraint rather than aggression.


Measured Conduct

Maharashtra’s politics has long been known for sharp strategies, strong personalities and open confrontations. Many leaders here believe politics must be fought loudly and aggressively. Sunetra Pawar appears to belong to a different school of thought. She is calm, measured and restrained in her public conduct. She does not rush to microphones or social media. She does not respond instantly to provocation. In an era where political success is often measured by visibility and noise, this silence has drawn attention. Some see it as weakness. Others see it as maturity. Politics, however, is not only about speaking. It is also about listening, observing and choosing the right moment. Many experienced observers believe that patience, emotional balance and timing are underrated political strengths. Sunetra Pawar seems to be relying on these qualities as she takes her first steps.


It is impossible to discuss Sunetra Pawar without mentioning her surname. Critics have been quick to label her rise as dynastic politics. Supporters respond by saying that a family name may open the door, but it cannot guarantee survival inside the political room. History shows that many leaders with strong backgrounds have failed, while others without any political lineage have succeeded. Ultimately, politics is unforgiving. It rewards performance, not privilege. Sunetra Pawar will be judged not by who she is related to, but by what she delivers. Her real challenge is to move from being seen as a symbol of continuity to being recognised as an individual decision-maker.


Great Expectations

Public expectations from Sunetra Pawar are unusually high. Part of this is because she represents a rare example of a woman entering the top level of state leadership at a time of transition. Part of it is because her entry comes during a period when Maharashtra faces serious governance challenges. Farmers are struggling with unpredictable weather and debt. Cities are under pressure from infrastructure stress and rising populations. Employment concerns remain unresolved. State finances demand discipline and clarity. These are not symbolic problems. They require administrative focus and political courage. The real test for Sunetra Pawar will be whether her calm political style can translate into effective governance.


Television debates and digital platforms have been divided in their assessment. Some commentators question her administrative experience and political exposure. Others argue that leadership is not always built through years of public speeches but through life experience, emotional resilience and the ability to learn quickly. Social media discussions often swing between extreme opinions. But serious political observers are taking a more cautious view. They argue that judging a leader too early can be misleading. Politics is a long-distance race, not a sprint. What is interesting is that even her critics admit one thing: she has not made any major mistakes so far.


One important aspect of politics is understanding people. Power attracts supporters, advisors and well-wishers. Not all of them are sincere. Successful leaders are those who learn to identify who stands with them during difficult times. Sunetra Pawar appears aware of this reality. Her slow and careful approach suggests she is observing before acting. She is learning the difference between loyalty and convenience, between advice and pressure. This phase of observation may not look dramatic, but it is often crucial in building long-term political stability. Personal tragedy can break leaders or strengthen them.


The way Sunetra Pawar has handled loss with dignity, silence and composure, has quietly earned respect across political lines. Emotional strength is rarely discussed in political analysis, yet it plays a major role in leadership. Leaders are tested not only by success but also by how they stand firm when circumstances are difficult. Her calm public presence during a sensitive phase suggests inner stability, a quality that can help in high-pressure political environments.


The road ahead is not easy. Political rivals will closely watch her decisions. Any hesitation may be portrayed as weakness. Any strong decision may invite criticism. There is also the constant risk of being seen only through the lens of family legacy rather than individual capability. Factional politics within parties, pressure from allies and expectations from the public will demand careful balance. Mistakes will not be forgiven easily. There is no final answer yet. It is too early to declare success or failure. What can be said with certainty is that she brings a different political style based on patience rather than provocation.


Politics does not always reward the loudest voice. Sometimes it rewards those who wait, watch and act at the right moment. Sunetra Pawar’s journey has just begun. Maharashtra is watching with curiosity. Only time will decide whether this moment becomes a turning point or just a transition.
