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.

Election Quagmire

Updated: Jan 2, 2025

Election Quagmire

Mozambique is at a perilous crossroads. The Constitutional Council’s recent ruling upholding the contentious October election results has entrenched the ruling Frelimo party’s long grip on power. Yet the outcome has done little to calm the fury simmering in the streets. The announcement confirmed Daniel Chapo’s presidency and gave his challenger, Venancio Mondlane, a few extra percentage points — an arithmetic adjustment that has only deepened public distrust in the electoral process. With over 110 lives lost in post-election violence, the nation’s path seems headed toward more bloodshed, instability, and economic crisis.


Mozambique’s political history offers insight into its current crisis. After gaining independence from Portugal in 1975, the country became a one-party state under Frelimo (Mozambique Liberation Front), a Marxist-Leninist movement that emerged victorious in the struggle against colonial rule. The party’s early years were marked by ambitious but uneven socialist experiments, including nationalized industries and land redistribution. However, these policies struggled to take root in a war-torn society.


After defeating the Portuguese, Mozambique was plunged into a brutal 15-year civil war with the Renamo rebel group, backed by apartheid-era South Africa and Rhodesia. The conflict, which ended in 1992, killed over a million people and left the country among the world’s poorest. Though Frelimo adopted a multiparty system and market reforms in the 1990s, it never truly relinquished its grip on power.


Chapo, like many Frelimo leaders before him, stands as a product of this historical continuity. His predecessors, including outgoing President Filipe Nyusi, were veterans of the liberation struggle. Yet their reverence among older Mozambicans has not translated into support among the country’s youth.


Mozambique’s demographics underscore the depth of the crisis. With more than half of its 34 million people aged 19 and below, the country is one of the youngest in the world. For many of these young people, the triumphs of the liberation era are distant echoes. Instead, their formative experiences are defined by soaring unemployment, endemic corruption, and chronic insecurity. The north, plagued by an Islamist insurgency since 2017, symbolizes Mozambique’s decline, with over a million displaced and Cabo Delgado in ruins despite its gas reserves. Cyclone Chido’s destruction in December worsened the region’s plight. Mondlane, leader of Podemos, tapped into widespread discontent with Frelimo, particularly among disillusioned urban youth. Although officially winning just 24 percent, he claims a majority, accusing Frelimo of electoral fraud.


The weeks following the election have been among the most violent in Mozambique’s recent history. Protesters, galvanized by Mondlane’s fiery rhetoric, have clashed with security forces in Maputo and beyond. Businesses have shuttered, ports have stalled and neighbouring countries have temporarily closed borders, further isolating the beleaguered nation.


Frelimo’s response has been predictably authoritarian. Soldiers patrol the streets, the internet is intermittently shut down, and thousands of demonstrators have been arrested. Yet this heavy-handedness is as much a sign of weakness as strength. Unlike in previous decades, when state machinery was firmly aligned with Frelimo, cracks are beginning to show in the party’s ability to command allegiance.


Mozambique’s descent into chaos is a grim reminder of the fragility of postcolonial states with entrenched ruling parties. While Botswana, South Africa and Namibia have seen opposition parties gain ground in recent elections, Mozambique remains trapped in the inertia of a liberation-era monopoly.


Mozambique’s future now hinges on whether its leaders—both in government and the opposition—can rise above the zero-sum politics that has long defined its landscape. For now, the streets remain restless, the nation divided and the revolution unfinished.
