    What is Antimicrobial Resistance (AMR)?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Anti-Microbial Resistance

    Mains level: Overdose of anti-biotics

    The Global Research on Antimicrobial Resistance (GRAM) report published in The Lancet provides the most comprehensive estimate of the global impact of Antimicrobial Resistance (AMR) so far.

    What is AMR?

    • Antimicrobial resistance (AMR or AR) is the ability of a microbe to resist the effects of medication that once could successfully treat the microbe
    • Antibiotic resistance occurs naturally, but misuse of antibiotics in humans and animals is accelerating the process.
    • A growing number of infections – such as pneumonia, tuberculosis, gonorrhoea, and salmonellosis – are becoming harder to treat as the antibiotics used to treat them become less effective.
    • It leads to higher medical costs, prolonged hospital stays, and increased mortality.

    How does it occur?

    • Antibiotics are medicines used to prevent and treat bacterial infections.
    • Antibiotic resistance occurs when bacteria change in response to the use of these medicines.
    • Bacteria, not humans or animals, become antibiotic-resistant.
    • These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria.

    What did the GRAM report find?

    • AMR is a leading cause of death globally, higher than HIV/AIDS or malaria.
    • As many as 4.95 million deaths may be associated with bacterial AMR in 2019.
    • Lower respiratory tract infections accounted for more than 1.5 million deaths associated with resistance in 2019, making it the most common infectious syndrome.

    The six leading pathogens for deaths associated with resistance were:

    1. Escherichia coli (E. Coli)
    2. Staphylococcus aureus
    3. Klebsiella pneumonia
    4. Streptococcus pneumonia
    5. Acinetobacter baumannii
    6. Pseudomonas aeruginosa

    What are the implications of this study?

    • Common infections such as lower respiratory tract infections, bloodstream infections, and intra-abdominal infections are now killing hundreds of thousands of people every.
    • This includes historically treatable illnesses, such as pneumonia, hospital-acquired infections, and foodborne ailments.

    Way forward

    • Doctors recommend greater action to monitor and control infections, globally, nationally and within individual hospitals.
    • Access to vaccines, clean water and sanitation ought to be expanded.
    • The use of antibiotics unrelated to treating human disease, such as in food and animal production must be “optimised” and finally they recommend being “more thoughtful”.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Sammakka-Sarakka Jatara

    Mains level: Not Much

    Medaram, a tiny village in Telangana’s tribal heartland of Mulugu district, is getting ready to host the Sammakka-Sarakka jatara, billed as the country’s biggest tribal fair.

    Sammakka-Sarakka Jatara

    • The mega four-day jatara, scheduled to begin on February 16 in Medaram. It takes place once in two years.

    • The sacred site in Medaram and its surrounding Jampanna vagu, named after tribal martyr Jampanna, son of Sammakka, comes alive with lakhs of devotees during the four-day jatara.

    Why do tribals come to Medaram?

    • This festival commemorates a tribal revolt led by Sammakka and Saralamma, a mother-daughter duo, against levy of taxes on tribal people during drought conditions by the then Kakatiya rulers in the 12th century.
    • Tribals (and others) flock to Medaram during the jatara not just from Telangana and Andhra Pradesh but also from as far as Madhya Pradesh, Jharkhand, Chhattisgarh and Maharashtra.
    • Sammakka and Saralamma are revered by devotees as tribal goddesses, and devotees make offerings to propitiate them to bestow health and wealth.
    • All the rituals at the jatara site are held in tune with tribal traditions under the aegis of tribal priests.

    Features of the celebrations

    • One of the striking features of the tribal fair is the offering of jaggery to the tribal goddess at the altars (bamboo poles).
    • It encompasses common features of tribal fairs – die-hard devotees going into a trance, the sacrifice of fowls and goats, besides pulsating traditional drum beats accompanying folk songs.

    Mains level: Ancient Indian Civilizations

    A reconnaissance survey in the sea off the coast of Korkai in Thoothukudi district where Tamiraparani River joins the sea, which finds mention in Sangam literature, will be undertaken by the Tamil Nadu Archaeology Department.

    About Tamiraparani River

    • The Thamirabarani or Tamraparni or Porunai is a perennial river that originates from the Agastyarkoodam peak of the Pothigai hills of the Western Ghats.
    • It flows through the Tirunelveli and Thoothukudi districts of the Tamil Nadu state of southern India into the Gulf of Mannar.
    • It was called the Tamraparni River in the pre-classical period, a name it lent to the island of Sri Lanka.
    • The old Tamil name of the river is Porunai.

    Its history

    • Its many name derivations of Tan Porunai include Tampraparani, Tamirabarni, Tamiravaruni.
    • Tan Porunai nathi finds mention by classical Tamil poets in ancient Sangam Tamil literature Purananuru.
    • Recognised as a holy river in Sanskrit literature Puranas, Mahabharata and Ramayana, the river was famed in the Early Pandyan Kingdom for its pearl and conch fisheries and trade.
    • The movement of people, including the faithful, trade merchants and toddy tapers from Tamraparni river to northwestern Sri Lanka led to the shared appellation of the name for the closely connected region.
    • One important historical document on the river is the treatise Tamraparni Mahatmyam.
    • It has many ancient temples along its banks. A hamlet known as Appankoil is located on the northern side of the river.

    Back2Basics: Keeladi Civilization

    • The Keeladi tale began to unravel in March 2015 when first round of excavation was undertaken by the Archaeological Survey of India (ASI).
    • It unearthed antiquities providing crucial evidence to understanding the missing links of the Iron Age [12th century BCE to 6th century BCE] to the Early Historic Period [6th century BCE to 4th century BCE].
    • Further excavations threw up strong clues about the existence of a Tamil Civilization that had trade links with other regions in the country and abroad.
    • This civilization has been described by Tamil poets belonging to the Sangam period.
    • Results of carbon dating of a few artifacts traced their existence to 2nd century BCE (the Sangam period).

    Key findings in excavations

    • These included brick structures, terracotta ring wells, fallen roofing with tiles, golden ornaments, broken parts of copper objects, iron implements, terracotta chess pieces, ear ornaments, spindle whorls, figurines.
    • It also had black and redware, rouletted ware and a few pieces of Arretine ware, besides beads made of glass, terracotta and semi-precious stones.

    Nusantara City: New Capital of Indonesia

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Nusantara

    Mains level: NA

    Indonesia passed a bill replacing its capital Jakarta with East Kalimantan, situated to the east of Borneo island. The new capital city of the country will be called Nusantara.

    About Nusantara

    • The New State Capital Law Bill has been drafted by a special committee set up by Widodo’s government and makes Nusantara, also called IKN, the capital of the Republic of Indonesia.
    • The transfer of the status of Jakarta as Indonesia’s capital to Nusantara, where 256,142 hectares of land has been set aside for the project, will take place in the “first semester” of 2024.
    • East Kalimantan, where the new capital will be, as per the bill is said to have a world-city vision.
    • It will be designed and managed with the objective of becoming a sustainable city in the world.

    Why is Indonesia changing its capital city?

    • The new location is very strategic – it’s in the centre of Indonesia and close to urban areas.
    • The burden Jakarta is holding right now is too heavy as the centre of governance, business, finance, trade and services.
    • Jakarta is also infamous for being the worlds’ first sinking capital city due to rising sea levels.
    • The city’s pollution levels are so bad that it has been ranking as one of the most polluted cities in the world for years.
    • Another important reason to shift the capital from Java island to Borneo island has been the growing inequality – financial and otherwise.

    Where is East Kalimantan?

    • East Kalimantan is 2,300 kilometres from Jakarta on the eastern side of Borneo island, shared by Indonesia, Malaysia and Brunei.
    • The new capital will be located in the North Penajam Paser and Kutai Kartanegara regions.
    • East Kalimantan is an area with immense water resources and habitable terrain.
    • East Kalimantan is rich in flora and fauna.

    Why Nusantara?

    • Nusantara is an old Javanese term that means ‘archipelago’.
    • Nusantara has historical, sociological, and philosophical aspects attached to the name.
    • The name would represent Indonesia as a whole and would show the potential of the nation.

    What are the other countries that have changed capitals?

    • Indonesia is not the first country to change its capital city.
    • There has been a long list of countries that have changed their capitals for various reasons. Brazil changed its capital city from Rio De Janerio to Brasilia, a more centrally-located city, in 1960.
    • In 1991, Nigeria hanged the country’s capital from Lagos to Abuja.
    • Kazakhstan moved its capital city from Almaty, which is still its commercial centre, to Nur-Sultan in 1997.
    • Myanmar changed its capital from Rangoon to Naypyidaw in 2005.

  • Air Pollution

    What are Smog Towers?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Smog Tower

    Mains level: Effectiveness of smog towers

    Some researchers in New Delhi have observed paradoxical phenomena near the smog towers. The air closest to the tower should be cleanest, but the device recorded the opposite in several instances.

    What are Smog Towers?

    • Smog towers are structures designed to work as large-scale air purifiers. They are fitted with multiple layers of air filters and fans at the base to suck the air.
    • After the polluted air enters the smog tower, it is purified by multiple layers before being re-circulated into the atmosphere.

    Structure of the Delhi smog tower

    • The structure is 24 m high, about as much as an 8-storey building — an 18-metre concrete tower, topped by a 6-metre-high canopy. At its base are 40 fans, 10 on each side.
    • Each fan can discharge 25 cubic metres per second of air, adding up to 1,000 cubic metres per second for the tower as a whole. Inside the tower in two layers are 5,000 filters.
    • The filters and fans have been imported from the United States.

    How does it work?

    • The tower uses a ‘downdraft air cleaning system’ developed by the University of Minnesota.
    • Polluted air is sucked in at a height of 24 m, and filtered air is released at the bottom of the tower, at a height of about 10 m from the ground.
    • When the fans at the bottom of the tower operate, the negative pressure created sucks in air from the top.
    • The ‘macro’ layer in the filter traps particles of 10 microns and larger, while the ‘micro’ layer filters smaller particles of around 0.3 microns.
    • The downdraft method is different from the system used in China, where a tower uses an ‘updraft’ system — air is sucked in from near the ground, and is propelled upwards by heating and convection.
    • Filtered air is released at the top of the tower.

    Likely impact

    • Computational fluid dynamics modelling suggests the tower could have an impact on the air quality up to 1 km from the tower.
    • The actual impact will also determine how the tower functions under different weather conditions, and how levels of PM2.5 vary with the flow of air.

    Issues with smog towers

    • Many experts say that the smog towers are not a viable method to clean city’s air.
    • The government had talked about 80% pollution reduction at inlet and outlet of the tower but never mentioned about the effect of distance from the tower.
    • Instead of spending ₹40 crore on two towers, the government could have spent the funds on several other options such as replacing the small and polluting industrial boilers or chimneys etc.

    How Republic Day tableaux are designed and selected

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Republic Day celebration

    Mains level: Not Much

    Recently, West Bengal’s tableau for the Republic Day parade was rejected without assigning any reasons or justifications.

    Who manages the R-Day Parade?

    • The Defence Ministry is the responsible authority for the Republic Day parade and the celebrations.
    • Around September, it invites all the states, the UTs, Central Government departments, and a few constitutional authorities to participate in the parade through tableaux.

    Managing Tableaux

    • The Defence Ministry shares the basic guidelines about what all the tableaux can or should include.
    • The tableaux of two different states/ UTs cannot be too similar, as the tableaux, together, should showcase the diversity of the country.
    • The tableaux cannot have any writing or use of logos, except for the name of the state/ UT/ department, which should be written in Hindi on the front, English on the back, and a regional language on the sides.
    • The Ministry also asks the participants to use eco-friendly material for the tableaux, and avoid the use of plastic or plastic-based products.

    How are the tableaux selected?

    • The selection process is elaborate and time-consuming.
    • The Defence Ministry constitutes an expert committee of distinguished persons from fields like art, culture, painting, sculpture, music, architecture, choreography, etc.

    Process of selection

    (1) Submission of sketches

    • First, the submitted sketches or designs of the proposals are scrutinised by this committee, which can make suggestions for any modifications in the sketch or design.
    • The sketch should be simple, colourful, easy to comprehend and should avoid unnecessary detail.
    • It should be self-explanatory, and should not need any written elaboration.

    (2) Music and Visuals

    • If there is a traditional dance involved with the tableau, it should be a folk dance, and the costumes and musical instruments should be traditional and authentic.
    • The proposal should include a video clipping of the dance.

    (3) 3D Models

    • Once approved, the next stage is for the participants to come up with three-dimensional models for their proposals.
    • These are again examined by the expert committee for final selection, taking in view several criteria.
    • In making the final selection the committee looks at a combination of factors, looking at the visual appeal, impact on the masses, idea/ theme of the tableaux, degree of detail involved.

    Do they have to be of a particular size?

    The Defence Ministry provides each participant with one tractor and one trailer, and the tableau should fit on that.

    • The ministry prohibits use of any additional tractor or trailer, or even any other vehicle to be part of it.
    • However, the participant can replace their ministry-provided tractor or trailer with other vehicles, but the total number should not be more than two vehicles.
    • The tractor has to be camouflaged in harmony with the tableau’s theme, and the ministry stipulates a distance of around six feet between the tractor and the trailer for turning and manoeuvering.
    • The dimensions of the trailer on which the tableau will be placed is 24 feet, 8 inches long; eight feet wide; four feet two inches high; with a load-bearing capacity of 10 tonnes.
    • The tableaux should not be more than 45 feet long, 14 feet wide and 16 feet high from the ground.

    (Republic Day celebrations from this year will start on January 23 instead of January 24 to include the birth anniversary of Netaji Subhas Chandra Bose.)

    Art-form in news: Kathak

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Kathak

    Mains level: NA

    Kathak legend Pandit Birju Maharaj has recently passed away.

    About Kathak

    • Kathak is one of the eight major forms of Indian classical dance.
    • The origin of Kathak is traditionally attributed to the traveling bards in of ancient northern India known as Kathakars or storytellers.
    • The term Kathak is derived from the Vedic Sanskrit word Katha which means “story”, and Kathakar which means “the one who tells a story”, or “to do with stories”.
    • Wandering Kathakars communicated stories from the great epics and ancient mythology through dance, songs and music.

    Its origin

    • Kathak dancers tell various stories through their hand movements and extensive footwork, their body movements and flexibility but most importantly through their facial expressions.
    • It evolved during the Bhakti movement, particularly by incorporating the childhood and stories of the Hindu god Krishna, as well as independently in the courts of north Indian kingdoms.
    • Kathak is unique in having both Hindu and Muslim gharanas and cultural elements of these gharanas.
    • Kathak performances include Urdu Ghazals and commonly used instruments brought during the Mughal period.

    Major gharanas

    • Kathak is found in three distinct forms, called “gharanas”, named after the cities where the Kathak dance tradition evolved – Jaipur, Banaras and Lucknow.
    • While the Jaipur gharana focuses more on the foot movements, the Banaras and Lucknow gharanas focus more on facial expressions and graceful hand movements.

    Performance details

    • It involves both Nritta (pure dance) and Nritya (expressive dance).
    • Stylistically, the Kathak dance form emphasizes rhythmic foot movements, adorned with small bells (Ghungroo) and the movement harmonized to the music.
    • The legs and torso are generally straight, and the story is told through a developed vocabulary based on the gestures of arms and upper body movement, facial expressions, neck movements, eyes and eyebrow movement, stage movements, bends and turns.
    • The main focus of the dance becomes the eyes and the foot movements.
    • The eyes work as a medium of communication of the story the dancer is trying to communicate. With the eyebrows the dancer gives various facial expressions.
    • A Kathak performance can be solo, duo or team. In a technical performance, the speed and energy the dancers exchange with the audience increases in multiples, that is the tempo doubles or quadruples.

  • Blockchain Technology: Prospects and Challenges

    Web 3.0: A vision for the future

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Web3

    Mains level: Web and Blockchain technology

    The concept of Web3, also called Web 3.0, used to describe a potential next phase of the internet, created quite a buzz in 2021.

    What is Web3?

    • The model, a decentralized internet to be run on blockchain technology, would be different from the versions in use, Web 1.0 and Web 2.0.
    • In web3, users will have ownership stakes in platforms and applications unlike now where tech giants control the platforms.

    Previous versions of Web

    To understand web3, we should start with Web 1.0 and Web 2.0.

    [1] Web 1

    • Web 1.0 is the world wide web or the internet that was invented in 1989. It became popular from 1993.
    • The internet in the Web 1.0 days was mostly static web pages where users would go to a website and then read and interact with the static information.
    • Even though there were e-commerce websites in the initial days it was still a closed environment and the users themselves could not create any content or post reviews on the internet.
    • Web 1.0 lasted until 1999.

    [2] Web 2

    • Web 2.0 started in some form in the late 1990s itself though 2004 was when most of its features were fully available. It is still the age of Web 2.0 now.
    • The differentiating characteristic of Web 2.0 compared to Web 1.0 is that users can create content.
    • They can interact and contribute in the form of comments, registering likes, sharing and uploading their photos or videos and perform other such activities.
    • Primarily, a social media kind of interaction is the differentiating trait of Web 2.0.

    What are some of the concerns?

    • In Web 2.0, most of the data in the internet and the internet traffic are owned or handled by very few behemoth companies ex. Google.
    • This has created issues related to data privacy, data security and abuse of such data.
    • There is a sense of disappointment that the original purpose of the internet has been distorted.
    • It is in this context that the buzz around Web3 is significant.

    Dawn of Web3

    • Gavin Wood, founder of Ethereum, a block chain technology company, used the term Web3 first in 2014 and in the past few years many others have added to the idea of Web3.
    • In 2021, owing to the popularity of crypto-currency, more discussions happened on Web3.

    How will Web3 address the problems of data monopoly?

    Web3 will deliver decentralized and fair internet where users control their own data.

    • Currently if a seller has to make a business to the buyer, both the buyer and seller need to be registered on a “shop” or “platform” like Amazon or Ebay or any such e-commerce portal.
    • What this “platform” currently does is that it authenticates that the buyer and seller are genuine parties for the transaction.
    • Web3 would try to remove the role of the “platform”.
    • For the buyer to be authenticated, the usual proofs aided by block chain technology will be used. The same goes for the seller.

    How is blockchain technology used here?

    • With block chain, the time and place of the transaction are recorded permanently.
    • Thus, Web3 enables peer to peer (seller to buyer) transaction by eliminating the role of the intermediary. This concept can be extended to other transactions also.
    • Consider a social media application where you want to share pictures with your followers.
    • It could be a broadcast operation from you aided by blockchain and you don’t need social media accounts for all the participants to be able to perform this.

    Another key feature: Decentralized Autonomous Organization

    • The key concepts in Web3 seen so far are peer to peer transaction and block chain.
    • The spirit of Web3 is Decentralized Autonomous Organization (DAO).
    • DAO is all about the business rules and governing rules in any transaction are transparently available for anyone to see and software will be written conforming to these rules.
    • Crypto-currency and block chain are technologies that follow the DAO principle.
    • With DAO, there is no need for a central authority to authenticate or validate.

    Will it take off?

    • We don’t know yet if Web3 will become the dominant mode of handling the internet but the questions it raises are relevant.
    • Web3 is in its very initial days and there is no consensus if it will take off like Web 1.0 or Web 2.0 did.
    • There is much skepticism from top tech brains in the industry and the academic community that Web3 does not solve the problems it purports to solve.
