KARNATAKA: HORTICULTURE / AGRICULTURE: Indian Institute of Horticultural Research (ICAR-IIHR) to hold Exclusive ‘Appe Midi’ Fair (tender mango) where 100 varieties to be on display, April 12-13

Appe midi is a traditional pickling variety of mango from Karnataka, which is grown in the Malnad region of the State-especially in Sirsi, Sagara, Siddapur, Thirthahally, Kumata, Sakleshpur, Kodagu and Chikkamagaluru.

Thanks to the growing popularity of ‘appe midi ’ (tender mango in Kannada), the Indian Institute of Horticultural Research (ICAR-IIHR) in Hesaraghatta for the first time will conduct an exclusive ‘appe midi’ mango fair, where 100 varieties of such mangoes will be displayed.

Appe midi is a traditional pickling variety of mango from Karnataka, which is grown in the Malnad region of the State-especially in Sirsi, Sagara, Siddapur, Thirthahally, Kumata, Sakleshpur, Kodagu and Chikkamagaluru.

The fair will be held on April 12 and 13 on the IIHR campus in Hessarghatta.

Creating awareness

Speaking to The Hindu, M. Sankaran, Principal scientist, division of fruit crops, ICAR-IIHR, said, “Appe midi mangoes have a unique position with respect to the diversity of pickling mango varieties. Appe midi is the king of all tender mangoes as far as its use in the pickle industry is concerned. Since there is a demand and awareness has to be created on this variety of mangoes, we thought of conducting an exclusive fair.”

The IIHR will display 100 varieties of tender mangoes at the fair, which are preserved by IIHR and also grown by farmers in various parts of the State. “The custodian farmers from across the State will participate at the fair where 100 appe midi mango genotypes will be displayed. The pickle manufacturers will also sell their products made of tender mango. Apart from this, we will also distribute limited appe midi mango saplings to farmers,” Mr. Sankaran added.

According to IIHR, the pickles prepared from appe midi mangoes make for an exquisite culinary experience. The demand for pickles varies from 4,000 to 5,000 tonnes per year, translating to ₹100 crore per year.

Unorganised market

“A good quality tender mango costs ₹2 to 3; the price for a quintal could go up to almost ₹6,000, depending on demand and availability. Since the supply of appe midi meets only one-tenth of demand in the market, they are often mixed in with ordinary tender mangoes. This is not an organised market compared to others. Appe midi products have a high potential for marketing and need attention for conservation. The mango’s unique size and taste make its pickle one of the best in the country, with its fragrance so strong that adding just a few midis to an ordinary pickle can change its taste and smell,” Mr. Sankaran explained.

A wild appe midi tree can yield several tonnes of tender mango, with features varying from tree to tree. In Karnataka, 100 farm households are engaged in making appe midi pickles producing at least 100 tones of pickle a year. ICAR-IIHR has so far surveyed, collected and conserved more than 250 accessions of appe midi mangoes. These mangoes have a huge market in Goa, Tamil Nadu and Kerala, according to IIHR.

KARNATAKA-INTERNATIONAL: CULTURE & ARTS: Comparative Study on Poetry of Basavanna and Hopkins released

“The Poetry of G.M. Hopkins and Basavanna: A Comparative Study”, authored by Basavaraj P. Donur, Registrar, Central University of Karnataka, was released at Basava Samithi office in Bengaluru on Saturday.

“If Hopkins knew about Basavnna and his ideas he would have adopted Lingayat philosophy,” said Manu Baligar, member, Central Sahitya Academy, after the release of the work.

“Basavanna protested against the exploitative religious system and gave Lingayat philosophy and Hopkins also protested against the rigidity and orthodox practices of the Church of England. Though he lived in the 19th century, Hopkins’ ideas have a lot of similarities with that of Basavanna’s. It shows ideas of great thinkers always correlate and are timeless,” he said.

Dr. Baligar said that the work is meant for serious readers and suggested its translation into Kannada for taking it to a larger section of readers.

Central University Vice-Chancellor Battu Satyanarayana, faculty members Vikram Visaji, Ganapati Sinnoor, Siddanna Langoti, Prof. Donur and others were present.

KARNATAKA: GREEN ENERGY /SCIENCE & TECHNOLOGY: IISc Supercapacitor to replace Batteries in EVs

The supercapacitor is fully functional and can be deployed in energy-storage devices like electric car batteries or any miniaturised system by on-chip integration.

Researchers at the Indian Institute of Science (IISc) have developed a new type of supercapacitor that can replace batteries in streetlights, electric cars and medical devices.

The supercapacitor, developed by researchers from IISc’s Department of Instrumentation and Applied Physics (IAP), is different from others, as it is smaller or ‘ultra-micro’, but capable of storing larger amounts of energy. Hence, the supercapacitor can be easier to use in smaller electronic devices, eliminating the need for batteries, while ensuring that the device stays charged for a longer time.

“Most of these devices are currently powered by batteries. However, over time, these batteries lose their ability to store charge and therefore have a limited shelf-life. Capacitors, on the other hand, can store an electrical charge for much longer, by their design. Supercapacitors, on the other hand, combine the best of both batteries and capacitors — they can store and release large amounts of energy, and are therefore highly sought-after for next-generation electronic devices,” the researchers said.

Abha Misra, an IAP professor and a corresponding study author, said the supercapacitor used Field Effect Transistors (FETs) instead of metallic electrodes, which are more commonly used, as charge collectors. “Using FET as an electrode for supercapacitors is something new for tuning charge in a capacitor,” she said.

During their tests, they found that the ultra-micro supercapacitor, due to the materials used, was able to increase capacitance (ability to store energy as electricity within the device) to 3,000 per cent. This was compared to a regular supercapacitor, which showed only an 18 per cent increase. The key was the use of molybdenum disulphide (MoS2) and graphene in increasing the mobility of electrons within the supercapacitor.

“In future, we are planning to explore if replacing MoS2 with other materials can increase the capacitance of the supercapacitor even more. The supercapacitor is fully functional and can be deployed in energy-storage devices like electric car batteries or any miniaturised system by on-chip integration. We are also planning to apply for a patent on the supercapacitor,” they said.

NATIONAL: SCIENCE & TECHNOLOGY / COMMUNICATIONS: For the 1st time in India, Raman Research Institute Researchers Successfully Demonstrate Secure Communication between Stationary Source and Moving Receiver using Quantum Key Distribution (QKD)

The technology could help India design secure communication channels, especially for defence and strategic purposes, enhance cyber security and make online transactions safer.

For the first time in India, researchers at the Raman Research Institute (RRI) have successfully demonstrated secure communication established between a stationary source and a moving receiver using Quantum Key Distribution (QKD).

Prof. Urbasi Sinha, who led the team of researchers, said that this breakthrough demonstration could pave the way for ground-to-satellite-based secure quantum communication.

The successful experimental demonstration, which was performed at the institute in March, could also help India design and provide secure communication channels, especially for defence and strategic purposes, enhance cyber security and make online transactions safer.

In order to achieve this feat, Prof. Sinha and her team at the Quantum Information and ComputingI (QuIC) lab deployed an indigenously deployed Pointing, Acquisition and Tracking (PAT) system.

This PAT system assisted the ground-based source in tracking the moving receiver, in this case, a terrestrial vehicle, a few metres apart.

Prof Sinha added that the present demonstration is in continuation to the QuIC lab’s February 2021 demonstration of QKD between two buildings using an atmospheric free space channel.

“Just like our team achieved the first secure quantum communication between two buildings for the first time in India, we are equally delighted to be the first Indian team to achieve secure quantum communication between a stationary source and a moving platform, a critical milestone in our quest towards satellite-based quantum communications,” Prof Sinha added.

Relevance of quantum technology

While present-day classical cryptography follows the encryption and decryption of messages, its security gets challenged by quantum computers and other revolutionary algorithmic breakthroughs.

According to RRI, the obvious solution then is to use quantum cryptography.

“Security based on laws of quantum mechanics is a paradigm change from the current means of security based on mathematical hardness of problems. Quantum Key Distribution is currently the most secure means of facing any threats from algorithmic breakthroughs in classical computing as well as the advent of quantum computers,” Prof Sinha said, sharing the relevance of quantum technology in the increasing online mode of transactions.

This research by Prof Sinha’s team is part of Quantum Experiments using Satellite Technology (QuEST), for which RRI has been collaborating with the U.R. Rao Satellite Centre of Indian Space Research Organisation (ISRO) since 2017.
