Today is World Bicycle Day, a day celebrated to commemorate the joy of cycling. In a country like Netherlands, almost every person owns a cycle, and 99.1% are cyclists! But a city like Bengaluru -- almost thrice as big  and with 12 times more population -- loses hands down to Amsterdam, in citizens choosing to cycle. Why is that so? And what can be done to make people here fall in love with their bikes? The Research Matters team caught up with Prof. Ashish Verma, an Associate Professor at the Department of Civil Engineering, at the Indian Institute of Science (IISc), Bengaluru.

The public transport system of Bengaluru is plagued by delays and inefficiencies that have resulted in huge losses to BMTC, the operator, and lack of quality services to the common people. Now, scientists from the Indian Institute of Science have proposed a new model of transport that aims to increase bus efficiency, reduce or eliminate delays and save money for both the transport corporation and its users - the people. The new model, researchers claim, could be a win-win situation for both and could revive the appeal of public transportation.

World Water Day

 

This 22nd of March, on the occasion of World Water Day, Research Matters caught up with Prof MS Mohan Kumar, a Professor at the Department of Civil Engineering, Indian Institute of Science (IISc), Bengaluru. He is also the Chairman of the Indo-French Cell for Water Resources and an Associate Faculty at the Interdisciplinary Centre for Water Research (ICWaR) at IISc and an ex-Secretary of the Karnataka State Council for Science & Technology.  Apart from his role at the institute, Prof. Kumar has also extensively worked with government bodies such as the Bangalore Water Supply and Sewerage Board (BWSSB), Karnataka Urban Water Supply and Drainage Board (KUWSDB) and Bangalore Development Authority (BDA).

In 1948, celebrated physicist and Nobel laureate, Richard Feynman introduced what came to be called Feynman diagrams. These were a pictorial representation of mathematical equations and served as a powerful tool in understanding and visualizing complex interactions between sub-atomic particles like protons and electrons. But this simplistic tool could not handle complex problems, where particles underwent many interactions, but instead produced incomprehensible and confounding answers, like infinities.

This year’s National Science Day, celebrated to commemorate the discovery of Dr. C V Raman’s ‘Raman Effect’, is themed around ‘Science and Technology for Specially Abled Persons’. One billion people, or 15% of the world’s population, experience some form of disability today, and the prevalence of disability is highest in developing countries like India. A report by World Bank estimates that about 110-190 million of them experience significant disabilities.  ‘Persons with disabilities’ or PwDs include those who have long-term physical, mental, intellectual or sensory impairments which may hinder their full and effective participation in the society.

Many lifesaving medical devices such as urinary catheters, pacemakers, intrauterine devices and voice prosthesis, which are usually inserted into some part of the body, are plagued by a common problem – ‘bacterial biofilms’. These ‘biofilms’ grow on the surfaces of these devices and may cause infections. They are harder to treat than individual bacteria and need about 1000 – 10000 times stronger dose of antibiotics. But this may no longer be the case, as a group of scientists led by Prof. Dipshikha Chakravortty and Prof. Jagadeesh Gopalan from the Indian Institute of Science, Bangalore, have found a novel method to fight biofilm infections.

Clustering is a method of grouping a set of objects or data points according to similarity, and then extracting information from this data set to a logical structure. The researchers employed various statistical tools to group 36 GCMs from Coupled Model Intercomparison Project Phase 5 (CMIP5) database with reference to maximum temperature (MAXT), minimum temperature (MINT) and the combination of maximum and minimum temperature (COMBT) in India. CMIP5 aims to provide a framework for how to conduct coordinated climate change experiments during the next five years. Assessment of these temperature related variables is essential because they are instrumental in managing the hydrological cycle.

Professor Praveen Kumar, Materials Engineering, IISc

Dropped your mobile phone? You may soon stop worrying about it, thanks to the newly discovered phenomena related to carbon nanotube foam used as a shock-absorbent material in mobile phones. As a material scientist, Prof. Praveen Kumar’s work on studying the mechanical behaviour of materials has earned him various awards, the most recent ones being the Indian National Science Academy Young Scientist Award, 2016, National Academy of Science, India -Young Scientist Platinum Jubilee awards - 2016 and Associate of Indian Academy of Science. In his Thermo-Electro-Mechanical Behaviour Lab at the Department of Materials Engineering, Indian Institute of Science, Prof. Kumar and his students study the effects of size and electric fields on mechanical properties of materials and materials processing.
