Pearls are one of the most beautiful gemstones. Their white sheen undoubtedly bears the mark of purity and adorn the wearer with an added charm. Pearls come in a range of colours, from black to pure white, some shades being pinkish, or even bluish. Hyderabad, the southern city of India is often hailed as the 'City of Pearls'. Many people visit Hyderabad each year to get their hands on the beautiful pearl jewellery that is made here.

The Nizams of Hyderabad were extremely fond of pearls. They often gifted their wives, the Begums, elaborate strands of pure white pearls. During their reign, they ordered the pearls from various parts of the globe to be brought to their abode. Most of their pearls came from the Arabian Gulf which has the most exquisite type of this gemstone. When the world's best pearls conglomerated in one place, Hyderabad became famous for being the pearl hub of the world. This is how it began its trade.
Today, Hyderabad has kept up the name it was given by the Nizams. The pearls of Hyderabad invariably adorn most brides across India. Hyderabad pearls are often known as cultured pearls because of the treatment they undergo to become the impeccable jewels they are. Various shades of pearls are collected and graded according to size and type. Some of them are bleached if they are too dark. They are placed in hydrogen peroxide for a few days and then exposed to the sun. After this, they are washed, and graded again based on their lustre and sheen.

The pearls are then set into jewellery. Hyderabad is famous for its Satlada and Paanchlada, which is seven string and five string respectively. The pearls are strung into long lines and wound into neckpieces. Some of them are set with exquisite gemstones into bangles, earrings, and chains. The most expensive variety is called 'Basra'. The 'rice-pearl' is a unique kind of pearl found in South India. The most famous part of Hyderabad where these pearls are cultured is a place called Chandapet.

Hyderabad International Airport recorded the highest passenger footfall of nearly 48,000 on October 9. These include both domestic and international passengers. Before the Covid pandemic hit the operations in March last year, the airport was handling about 60,000 passengers daily. The airport also recorded 350 Air Traffic Movements (ATMs) which is 77 per cent of the pre-Covid numbers.
With the number of Covid cases is steadily coming down across India and the confidence in travel is gaining momentum, the average number of domestic passengers travelling from Hyderabad Airport per day rose to 31,137 in September as compared to 22,500 per day in July. According to the operator, GMR Hyderabad International Airport Ltd (GHIAL), the airport saw an increase in the number of flights across domestic sectors. The airport recorded a substantial rise in ATMs in September which was close to 9,000.
The passenger traffic surged in September with the airport witnessing traffic of 9.35 lakh domestic passengers as compared to 6.8 lakh domestic passengers in July. This is 62 per cent of the pre-Covid levels. The domestic passenger recovery at Hyderabad Airport was the highest amongst all metro airports during July and August.
The airport also saw a gradual increase in international travelers which was 1.2 lakh which is 41 per cent of the pre- Covid level. "Overall, the total passenger traffic footfall (domestic & international) reached 59 per cent of the pre-Covid levels in the month of September'21," GHIAL said on Monday.

As the passenger expectations around air travel are changing, visits to family and friends, leisure travel, business travels and students travelling to join international universities are on the rise. Fliers' demand for domestic destinations is on the rise. Hyderabad International Airport now connects to 65 domestic destinations as compared to 55 destinations in the pre-Covid period. In the last quarter, new domestic sectors like Rajkot, Srinagar, and Jamnagar were added.
The airport recently launched Air India's maiden direct flight from Hyderabad to London. The Air India non-stop flights operate between Hyderabad International Airport and Heathrow Airport twice a week - Monday and Friday. Also, under the UDAN initiative to bolster regional connectivity, it launched Star Air's maiden flight from Hyderabad to Jamnagar. Domestic destinations like Jamnagar, Jammu, and Chandigarh recorded huge growth in passenger volume flying out from Hyderabad. Jamnagar recorded a passenger growth rate of 346 per cent in September as compared to August while Jammu recorded 286 per cent and Chandigarh close to 244 per cent.
The most popular domestic destination in terms of passenger volume was Delhi, Mumbai, and Bengaluru. Dubai, Doha and Sharjah were the hottest destinations among international travelers. Along with leisure/vacation travel, SME business travel and visiting Friends & Relatives (VFR), students have largely contributed to the increase in passenger numbers, a GHIAL official said.

'IndiGau', India's first cattle genomic chip for the conservation of pure varieties of indigenous cattle breeds such as Gir, Kankrej, Sahiwal, Ongole etc., was launched here on Friday.
This indigenous chip has been developed by the concerted efforts of scientists at the National Institute of Animal Biotechnology (NAIB), Hyderabad, an autonomous institution under the aegis of the Department of Biotechnology, Ministry of Science and Technology.
"IndiGau is purely indigenous and the largest cattle chip in the world. It has 11,496 markers (SNPs), more than that placed on 777K Illumina chip of US and UK breeds. This chip for our own indigenous cows is a great example of Aatmanirbhar Bharat," said Union Minister of State for Science & Technology, Jitendra Singh.
This chip will have practical utility in the government schemes to achieve the goal of conservation of the indegenous breeds with better characters and help towards doubling the farmers' income by 2022, Singh added.
Renu Swarup, Secretary, Department of Biotechnology, informed that the department is looking forward to implement this technology in the field with the help of other agencies like NDDB, DAHDF, ICAR etc.
To further the use of this chip in generating phenotypic and genotypic correlations, the NIAB has entered into a collaborative agreement with the National Dairy Development Board (NDDB).
Researchers at the International Institute of Information Technology, Hyderabad (IIIT-H) have designed a unique charging solution for e-scooters.
Dr. Aftab Hussain, who heads the Processes, Architecture and Technologies Research in IoT (PATRIoT) division at IIIT-H and his team has designed a complete end-to-end charging solution from the electronic hardware components that are sturdy and safe enough for outdoor deployments to the software that contains an appropriate processor to control all input and output devices of the system.
In a paper titled, “Compact Electric Vehicle Charging Station Using Open Charge Point Protocol for E-Scooters” that has been presented at the 2021 International Conference on Sustainable Energy and Future Electric Transportation, Dr. Hussain and his team of researchers proposed a unique design and fabrication of charging equipment specifically for e-scooters.

Leveraging on the core strength of the lab which lies in flexible electronics, the researchers have used a flexible, inexpensive membrane for the keypad with a longer lifespan than a mechanical keypad. Much like the interface at an ATM, the user has to swipe an RFID card that authenticates her before she enters the amount for which charging has to be done. Safety features such as emergency disconnection of AC power supply in case it goes beyond a minimum threshold, or in case of hardware faults have also been incorporated.
Deeksha Devendra, the lead author of the paper, cites the compact nature of the charger that makes it possible to deploy it in densely populated urban centers where a need for such chargers is most felt.
“Current EV charger designs are bulky, requiring land usage rights, whereas this device can be mounted on a street lamp,” she said. The USP of the system though lies in the Open Charge Point Protocol (OCPP) that it is based on. With this, charging stations are no longer vendor-specific.
“Our design scores over others’ as it allows users to roam between the charging stations irrespective of the vehicle manufacturer, whether it is an Okinawa or a Hero e-scooter,” said Deeksha. “It’s the OCPP which makes the entire system reliable, both in terms of data security, as well as compatibility with the entire national infrastructure,” said Dr. Hussain, adding that their system is ahead of the curve.
The team started working on the solution as the charging infrastructure for two-wheelers is yet to catch up.
The Professor said that the lack of non-standardized charging points for e-bikes, in particular, is going to be a problem for the country in the foreseeable future. “The current problem with e-scooters is that they can’t be charged just about anywhere. The existing charging systems are specifically tailored for each make of such vehicles. Users are typically tied to charging their e-bikes at home. And this again is tremendously inconvenient,” said Dr. Hussain.
With residential housing societies yet to ramp up their parking lot infrastructure with charging points, one needs to unplug the scooter battery – a tedious process in itself – physically carry it home, charge it and reconnect it before the next ride. Repeating the sequence of events on a regular basis is a dampener on the path to electric mobility. (IANS/KB)
