    About Lingaraj Temple

    • Lingaraja Temple is a temple dedicated to Shiva and is one of the oldest temples in Bhubaneswar, Odisha.
    • It represents the quintessence of the Kalinga Architecture and culminating the medieval stages of the architectural tradition at Bhubaneswar.
    • The temple is believed to be built by the kings from the Somavamsi dynasty, with later additions from the Ganga rulers.
    • It is built in the Deula style that has four components namely, vimana (structure containing the sanctum), jagamohana (assembly hall), natamandira (festival hall) and bhoga-mandapa (hall of offerings), each increasing in the height to its predecessor.

    • Bhubaneswar is called the Ekamra Kshetra as the deity of Lingaraja was originally under a mango tree (Ekamra) as noted in Ekamra Purana, a 13th-century Sanskrit treatise.
    • The temple has images of Vishnu, possibly because of the rising prominence of Jagannath sect emanating from the Ganga rulers who built the Jagannath Temple in Puri in the 12th century.

    Dwarf Planet Ceres

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Ceres and other dwarf planets

    Mains level: Not Much

    The dwarf planet Ceres, which lies in the asteroid belt between Mars and Jupiter now, has the status of an “ocean world”.

    Note various dwarf planets and the criteria making a planet dwarf, as mentioned in the B2b section.

    Ceres exploration

    • The dwarf planet was first spotted by Giuseppe Piazzi in 1801, who assumed that Ceres was the missing planet between Mars and Jupiter.
    • It was classified as a dwarf planet in 2006 and is the first dwarf planet to be orbited by a spacecraft.
    • In 2015, NASA’s Dawn reached it to study its surface, composition and history.

    What does it mean to be an “ocean world”?

    • With a crust that mixes ice, salts, rock-forming minerals and other materials, Ceres looks to be a remnant “ocean world,” wearing the chemistry of its Old Ocean and records of the interaction on its surface.
    • The observations from Dawn suggest the presence of briny liquid (saltwater) water under Ceres’s surface.
    • Scientists have determined that Ceres has a brine reservoir located about 40 km deep and which is hundreds of miles wide, making the dwarf planet, “water-rich”.

    Why do researchers study Ceres?

    • Scientists are interested in this dwarf planet because it hosts the possibility of having water, something that many other planets do not have.
    • Therefore, scientists look for signs of life on Ceres, a possibility that has also maintained scientists’ interest in the planet Mars, whose atmosphere was once warm enough to allow water to flow through it.
    • Another reason why scientists are interested in that studying it can give insights about the formation of the Solar System since it is considered to be a fossil from that time.

    Back2Basics: Dwarf Planets

    • As of today, there are officially five dwarf planets in our Solar System.
    • The most famous is Pluto, downgraded from the status of a planet in 2006.
    • The other four, in order of size, are Eris, Makemake, Haumea and Ceres. The sixth claimant for a dwarf planet is Hygiea, which so far has been taken to be an asteroid.
    • These four criteria are – that the body orbits around the Sun, it is not a moon, has not cleared the neighbourhood around its orbit and has enough mass for its gravity to pull it into a roughly spherical shape.

    Bhadbhut Project

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Infrastructure: Energy, Ports, Roads, Airports, Railways Etc.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Bhadbhut Project, Hilsa Fish

    Mains level: Not Much

    The Gujarat government recently awarded the contract for a the Bhadbhut project in Bharuch, Gujarat. It has faced protests from local fishermen for its likely impact on fishing patterns, notably those of hilsa.

    Make a note of major dams in India along with the rivers, terrain, major wildlife sanctuaries and national parks incident to these rivers.

    What is the Bhadbhut Project?

    • It is planned to be a 1.7-km causeway-cum-weir barrage with 90 gates, across the river Narmada, 5 km from Bhadbhut village, and 25 km from the mouth of the river, where it flows into the Gulf of Khambhat.
    • The barrage will stop most of the excess water flowing out of the Sardar Sarovar Dam from reaching the sea and thus create a “sweet water lake” of 600 mcm (million cubic metres) on the river.
    • The barrage will also have a six-lane road that will connect the left and right banks of the river and provide shorten the land distance between two large industrial estates in Surat and Bharuch.
    • The project also aims to prevent flooding in years when rainfall is higher than normal.
    • Embankments 22 km long will be made and will extend upstream towards Bharuch, from either side of the river.
    • The project is part of the larger Kalpasar Project, which entails the construction of a 30-km dam across the Gulf of Khambhat between Bharuch and Bhavnagar districts.
    • The reservoir is meant to tap the waters of the Narmada, Mahisagar and Sabarmati.

    Why are fishermen upset?

    • The barrage is expected to interfere with the migration and breeding cycle of hilsa.
    • A marine fish, hilsa migrate upstream and arrives in the brackish water of the Narmada estuary near Bharuch for spawning usually during the monsoon months of July and August, and continue doing so till November.
    • Once the barrage is built, it is expected to block its natural entry.

    About Hilsa Fish

    IUCN status: Least Concerned

    • The Hilsa is a species of fish related to the herring, in the family Clupeidae.
    • It is a very popular and sought-after food fish in the Indian Subcontinent.
    • Though it’s a saltwater fish, it migrates to sweet waters.
    • It is the national fish of Bangladesh and state symbol in the Indian states of West Bengal and Tripura.
    • The fish contributes about 12% of the total fish production and about 1.15% of GDP in Bangladesh.

    Death Valley records the highest temperature on Earth

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Death Valley, Mojave Desert

    Mains level: Not Much

    California’s Death Valley registered a temperature of 54.4 degrees Celsius or 129.9 degrees Fahrenheit on August 16, 2020, which, once verified, could be the hottest temperature ever recorded on Earth.

    Some years back, there was a question in the mains:

    Major hot deserts in the northern hemisphere are located between 20-30 degree north and on the western side of the continents. Why?

    Death Valley and its location

    • Death Valley is a desert valley in Eastern California, in the northern Mojave Desert, bordering the Great Basin Desert.
    • It is one of the hottest places on Earth, along with deserts in the Middle East and the Sahara.
    • The valley is extremely dry because it lies in the rain shadow of four major mountain ranges (including the Sierra Nevada and the Panamint Range).
    • Moisture moving inland from the Pacific Ocean must pass eastward over the mountains to reach Death Valley; as air masses are forced upward by each range, they cool and moisture condenses, to fall as rain or snow on the western slopes.
    • When the air masses reach Death Valley, most of the moisture has already been lost and there is little left to fall as precipitation.

    Key factors leading to its high temperature

    • Solar heating: The valley’s surface (consisting of soil, rocks, sand, etc.) undergoes intense solar heating because the air is clear and dry, and the land is dark and sparsely vegetated. This is especially noticeable in summer when the sun is nearly directly overhead.
    • Trapping of warm air: Warm air naturally rises and cools; in Death Valley, this air is subject to continual reheating as it is trapped by high, steep valley walls and recycled back to the valley floor.
    • Migration of warm air from other areas (advection): Warm desert regions adjacent to Death Valley, especially to the south and east, often heat air before it arrives in Death Valley.
    • Warm mountain winds: As winds are forced up and over mountains (e.g., the numerous ranges west of Death Valley), the winds can be warmed in several ways. The resulting dry, warm winds are known as foehn winds.

    RBI’s Positive Pay system

    Prelims Only | Economics | Mains Paper 3: Cyber Security

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Positive Pay Mechanism

    Mains level: Not Much

    The new ‘Positive Pay’ mechanism was recently introduced by the Reserve Bank of India (RBI).

    Try this PYQ:

    With reference to digital payments, consider the following statements:

    1. BHIM app allows the user to transfer money to anyone with a UPI-enabled bank account.
    2. While a chip-pin debit card has four factors authentication, BHIM app has only two factors of authentication.

    Which of the statements given above is/are correct? (CSP 2018)

    a) 1 only
    b) 2 only
    c) Both 1 and 2
    d) Neither 1 nor 2

    What is the move?

    • Issuers will be able to send all details to their bank, thereby ensuring faster clearance of cheques above Rs 50,000.
    • All cheques will be processed as per the information sent by the account holder at the time of issuance of cheques.
    • This will cover approximately 20 per cent of transactions by volume and 80 per cent by value.
    • It will make cheque payments safer and reduces instances of frauds.

    What is Positive Pay Mechanism?

    • Positive Pay is a fraud detection tool adopted by banks to protect customers against forged, altered or counterfeit cheques.
    • It crosses verifies all details of the cheque issued before funds are encashed by the beneficiary.
    • In case of a mismatch, the cheque is sent back to the issuer for examination.
    • By following such a system, a bank knows of a cheque being drawn by the customer even before it is deposited by the beneficiary into his/her account.

    How does the mechanism work?

    • Under Positive Pay feature, the issuer will first share the details of the issued cheque like cheque number, date, name of the payee, account number, amount and the likes through his/her net banking account.
    • Along with this, an image of the front and reverse side of the cheque is also required to be shared, before handing it over to the beneficiary.
    • When the beneficiary submits the cheque for encashment, the details are compared with those provided to the bank through Positive Pay.
    • If the details match, the cheque is honoured. However, in the case of mismatch, the cheque is referred to the issuer.
    • In this way, any cheque where any sort of fraud has happened cannot be cleared at all and hence, a depositor’s money can be protected.

    From UPSC perspective, the following things are important:

    Prelims level: Mauritius oil spill

    Mains level: Chemical disasters these days

    A Japanese ship recently struck a coral reef resulting in an oil spill of over 1,000 tonnes into the Indian Ocean near Mauritius.

    Try this PYQ:

    Q.Recently, “oil zapper’’ was in the news. What is it? (CSP 2011)

    (a) It is an eco-friendly technology for the remediation of oily sludge and oil spills.

    (b) It is the latest technology developed for undersea oil exploration.

    (c) It is a genetically engineered high biofuel-yielding maize variety.

    (d) It is the latest technology to control the accidentally caused flames from oil wells.

    What caused the Mauritius oil spill?

    • A Japanese vessel struck a coral reef resulting in an oil spill of over 1,000 tonnes into the Indian Ocean.
    • The ship was carrying an estimated 4,000 tonnes of oil.
    • The accident had taken place near two environmentally protected marine ecosystems and the Blue Bay Marine Park Reserve, which is a wetland of international importance.

    How dangerous are oil spills?

    • Oil spills affect marine life by exposing them to harsh elements and destroying their sources of food and habitat.
    • Further, both birds and mammals can die from hypothermia as a result of oil spills.
    • For instance, oil destroys the insulating ability of fur-bearing mammals, such as sea otters.
    • It also decreases the water repellency of birds’ feathers, without which they lose their ability to repel cold water.

    Some major incidents

    • Some of the world’s largest oil spills include the Persian Gulf War oil spill of 1991 when more than 380 million gallons of oil was poured into the northern Persian Gulf by Iraq’s forces.
    • The 2010 Deepwater Horizon oil spill in the Gulf of Mexico is also considered to be among the largest known accidental oil spills in history.
    • Starting April 20, 2010, over 4 million barrels of oil flowed over a period of 87 days into the Gulf of Mexico.

    How is the oil spill cleaned?

    • There are a few ways to clean up oil spills including skimming, in situ burning and by releasing chemical dispersants.
    • Skimming involves removing oil from the sea surface before it is able to reach the sensitive areas along the coastline.
    • In situ burning means burning a particular patch of oil after it has concentrated in one area.
    • Releasing chemical dispersants helps break down oil into smaller droplets, making it easier for microbes to consume, and further break it down into less harmful compounds.
    • Natural actions in aquatic environments such as weathering, evaporation, emulsification, biodegradation and oxidation can also accelerate the recovery of an affected area. But these occur differently in freshwater and marine environments.

    Story of our National Flag

    Prelims Only | | Mains Paper 1: Modern Indian History

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: National flag

    Mains level: NA

    The final design of the Indian National Flag, hoisted by PM Nehru on August 16, 1947, at Red Fort, had a history of several decades preceding independence.

    Note various personalities involved in the development of our National flag. It may be no wonder to accept a personality-based question on such topics.

    Story of our National Flag: A timeline

    (1) Public display for first time

    • Arguably the first national flag of India is said to have been hoisted on August 7, 1906, in Kolkata at the Parsee Bagan Square (Green Park).
    • It comprised three horizontal stripes of red, yellow and green, with Vande Mataram written in the middle.
    • Believed to have been designed by freedom activists Sachindra Prasad Bose and Hemchandra Kanungo, the red stripe on the flag had symbols of the sun and a crescent moon, and the green strip had eight half-open lotuses.

    (2) In Germany

    • In 1907, Madame Cama and her group of exiled revolutionaries hoisted an Indian flag in Germany in 1907 — this was the first Indian flag to be hoisted in a foreign land.

    (3) During the Home Rule Movement

    • In 1917, Dr Annie Besant and Lokmanya Tilak adopted a new flag as part of the Home Rule Movement.
    • It had five alternate red and four green horizontal stripes, and seven stars in the saptarishi configuration.
    • A white crescent and star occupied one top corner, and the other had Union Jack.

    (4) Final version by Pingali Venkayya

    • The design of the present-day Indian tricolour is largely attributed to Pingali Venkayya, an Indian freedom fighter.
    • He reportedly first met Mahatma Gandhi in South Africa during the second Anglo-Boer War (1899-1902), when he was posted there as part of the British Indian Army.
    • Years of research went into designing the national flag. In 1916, he even published a book with possible designs of Indian flags.
    • At the All India Congress Committee in Bezwada in 1921, Venkayya again met Gandhi and proposed a basic design of the flag, consisting of two red and green bands to symbolise the two major communities, Hindus and Muslims.

    (5) During Constituent Assembly

    • On July 22, 1947, when members of the Constituent Assembly of India, the first item on the agenda was reportedly a motion by Pandit Nehru, about adopting a national flag for free India.
    • It was proposed that “the National Flag of India shall be horizontal tricolour of deep saffron (Kesari), white and dark green in equal proportion.”
    • The white band was to have a wheel in navy blue (the charkha being replaced by the chakra), which appears on the abacus of the Sarnath Lion Capital of Ashoka.

    From UPSC perspective, the following things are important:

    Prelims level: BRR

    Mains level: Not Much

    In efforts to have a single source for all non-financial disclosures by corporates, a government-appointed panel has made various proposals on business responsibility reporting, including putting in place two formats for disclosing information.

    Try this PYQ:

    Which one of the following is not a feature of Limited Liability Partnership firm? (CSP 2010)

    (a) Partners should be less than 20

    (b) Partnership and management need not be separate

    (c) Internal governance may be decided by mutual agreement among partners

    (d) It is corporate body with perpetual succession

    What is the Business Responsibility Report (BRR)?

    • Business Responsibility  Report is a disclosure of the adoption of responsible business practices by a  listed company to all its stakeholders.
    • This is important considering the fact that these companies have accessed funds from the public, have an element of public interest involved, and are obligated to make exhaustive disclosures on a regular basis.
    • BSR is to be submitted as a part of the Annual Report.
    • It contains a standardized format for companies to report the actions undertaken by them towards the adoption of responsible business practices.
    • It has been designed to provide basic information about the company, information related to its performance and processes, and information on principles and core elements of the BSR.

    SEBI recommendations for BSR

    • As per the report, reporting may be done by top 1,000 listed companies in terms of their market capitalization or as prescribed by markets regulator SEBI.
    • The reporting requirement may be extended by MCA (Ministry of Corporate Affairs) to unlisted companies above specified thresholds of turnover and/ or paid-up capital.
    • The panel has suggested two formats for disclosures — a comprehensive format and a “lite version” — and also called for the implementation of the reporting requirements in a gradual and phased manner.
    • Smaller unlisted companies may adopt a lite version of the format, on a voluntary basis.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Plant growth hormones

    Mains level: Not Much

    A team of researchers at the Indian Institute of Science Education and Research (IISER), Bhopal, has conducted a study on seed germination that could have a major impact on agriculture.

    What is the study about?

    • The study aims to determine the optimum timing of seed germination and thus ensure high plant yields.
    • It focused on the interplay between plant hormones like abscisic acid (ABA) which inhibit the sprouting of the seed and environmental cues like light (which promotes the sprouting process) and darkness.

    Note the following plant hormones and their functions:

    Hormone

    Function
    Ethylene Fruit ripening and abscission
    Gibberellins Break the dormancy of seeds and buds; promote growth
    Cytokinins Promote cell division; prevent senescence
    Abscisic Acid Close the stomata; maintain dormancy
    Auxins Involved in tropisms and apical dominance

    What is Abscisic Acid? 

    • Humans have glands that secrete hormones at different times to stimulate body processes such as growth, development, and the breaking down of sugars.  
    • Plants also have hormones that stimulate processes that are necessary for them to live.  
    • Abscisic acid is a plant hormone involved in many developmental plant processes, such as dormancy and environmental stress response.  
    • Abscisic acid is produced in the roots of the plant as well as the terminal buds at the top of the plant. 

    Function of Abscisic Acid 

    Abscisic acid is involved in several plant functions.  

    • Plants have openings on the bottom side of their leaves, known as stomata. Stomata take in carbon dioxide and regulate water content. Abscisic acid has been found to function in the closing of these stomata during times when the plant does not require as much carbon dioxide or during times of drought when the plant cannot afford to lose much water through transpiration. 
    • One of the crucial functions of abscisic acid is to inhibit seed germination. Abscisic acid has been found to stop a seed from immediately germinating once it has been placed in the soil. It actually causes the seed to enter a period of dormancy.  
    • This is of great benefit to the plants because most seeds are formed at the end of the growing season, when conditions would not be favorable for a new plant to sprout. The abscisic acid causes the seed to wait until the time when conditions are more favorable to grow. This ensures greater success in the plant’s ability to grow and reproduce successfully. 
    • ABA functions in many plant developmental processes, including seed and bud dormancy, the control of organ size and stomatal closure. It is especially important for plants in the response to environmental stresses, including drought, soil salinity, cold tolerance, freezing tolerance, heat stress and heavy metal ion tolerance.
