    Cabinet approves mega 5G auction

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: 5G technology

    Mains level: Not Much

    The Union Cabinet has approved the auction of airwaves capable of offering fifth generation, or 5G, telecom services, including ultra-high-speed Internet, and gave its nod for setting up of captive 5G networks by big tech firms.

    What is the news?

    • The auction of over 72 GHz of the spectrum will be held by July-end.
    • Auctions will be held at reserve prices recommended by the sector regulator, Telecom Regulatory Authority of India (TRAI).
    • TRAI had earlier recommended about a 39% reduction in the reserve or floor price for the sale of 5G spectrum for mobile services.

    What is 5G technology?

    • 5G or fifth generation is the latest upgrade in the long-term evolution (LTE) mobile broadband networks.
    • It mainly works in 3 bands, namely low, mid and high-frequency spectrum — all of which have their own uses as well as limitations.

    Three bands of 5G

    (1) Low band spectrum

    • It has shown great promise in terms of coverage and speed of internet and data exchange, the maximum speed is limited to 100 Mbps (Megabits per second).
    • This means that while telcos can use and install it for commercial cellphones users who may not have specific demands for very high-speed internet, the low band spectrum may not be optimal for the specialized needs of the industry.

    (2) Mid-band spectrum

    • It offers higher speeds compared to the low band but has limitations in terms of coverage area and penetration of signals.
    • Telcos and companies, which have taken the lead on 5G, have indicated that this band may be used by industries and specialized factory units for building captive networks that can be molded into the needs of that particular industry.

    (3) High-band spectrum

    • It offers the highest speed of all the three bands, but has extremely limited coverage and signal penetration strength.
    • Internet speeds in the high-band spectrum of 5G have been tested to be as high as 20 Gbps (gigabits per second), while, in most cases, the maximum internet data speed in 4G has been recorded at 1 Gbps.

    Where does India stand in the 5G technology race?

    • On par with the global players, India had, in 2018, planned to start 5G services as soon as possible, with an aim to capitalize on the better network speeds and strength that the technology promised.
    • Indian private telecom players have been urging the DoT to lay out a clear road map of spectrum allocation and 5G frequency bands so that they would be able to plan the rollout of their services accordingly.
    • One big hurdle, however, is the lack of flow of cash and adequate capital with some companies due to their AGR dues.

    Global progress on 5G

    • More than governments, global telecom companies have started building 5G networks and rolling it out to their customers on a trial basis.
    • In countries like the US, some companies have taken the lead when it comes to rolling out commercial 5G for their users.
    • A South Korean company, which had started researching on 5G technology way back in 2011, has, on the other hand, take the lead when it comes to building the hardware for 5G networks for several companies.

    Managing Type 1 Diabetes

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Diabetes , its types

    Mains level: Not Much

    Last week, the Indian Council of Medical Research (IMCR) released guidelines for the diagnosis, treatment, and management for type-1 diabetes.

    Why such move?

    • India is considered the diabetes capital of the world, and the pandemic disproportionately affected those living with the disease.
    • Type 1 or childhood diabetes, however, is less talked about, although it can turn fatal without proper insulin therapy.
    • Type 1 diabetes is rarer than type 2. Only 2% of all hospital cases of diabetes in the country are type 1.

    What is Diabetes?

    • Diabetes is a chronic (long-lasting) health condition that affects how your body turns food into energy.
    • Most of the food you eat is broken down into sugar (also called glucose) and released into your bloodstream.
    • When your blood sugar goes up, it signals your pancreas to release insulin.

    What is Type 1 Diabetes?

    • Type 1 diabetes is a condition where the pancreas completely stops producing insulin.
    • Insulin is the hormone responsible for controlling the level of glucose in blood by increasing or decreasing absorption to the liver, fat, and other cells of the body.
    • This is unlike type 2 diabetes — which accounts for over 90% of all diabetes cases in the country — where the body’s insulin production either goes down or the cells become resistant to the insulin.

    How lethal diabetes is?

    • Type 1 diabetes is predominantly diagnosed in children and adolescents.
    • Although the prevalence is less, it is much more severe than type 2.
    • Unlike type 2 diabetes where the body produces some insulin and which can be managed using various pills, if a person with type 1 diabetes stops taking their insulin, they die within weeks.

    How rare is it?

    • There are over 10 lakh children and adolescents living with type 1 diabetes in the world, with India accounting for the highest number.
    • Of the 2.5 lakh people living with type 1 diabetes in India, 90,000 to 1 lakh are under the age of 14 years.
    • For context, the total number of people in India living with diabetes was 7.7 crore in 2019.
    • Among individuals who develop diabetes under the age of 25 years, 25.3% have type 2.

    Who is at risk of type 1 diabetes?

    • The exact cause of type 1 diabetes is unknown, but it is thought to be an auto-immune condition where the body’s immune system destroys the islets cells on the pancreas that produce insulin.
    • Genetic factors play a role in determining whether a person will get type-1 diabetes.
    • The risk of the disease in a child is 3% when the mother has it, 5% when the father has it, and 8% when a sibling has it.
    • The presence of certain genes is also strongly associated with the disease.

    What is Web 5.0?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Web and its evolution

    Mains level: Not Much

    Former Twitter CEO recently announced his vision for a new decentralized web platform that is being called Web 5.0 and is being built with an aim to return “ownership of data and identity to individuals”.

    Various versions of Web

    • Web 1.0 was the first generation of the global digital communications network. It is often referred to as the “read-only” Internet made of static web-pages that only allowed for passive engagement.
    • Web 2.0 was the “read and write” Internet. Users were now able to communicate with servers and other users leading to the creation of the social web. This is the World Wide Web that we use today.
    • Web 3.0 is an evolving term that is used to refer to the next generation of Internet – a “read-write-execute” web – with decentralization as its bedrock. It leverages the blockchain technology and will be driven by Artificial Intelligence and machine learning.
    • Web 4.0 is not really a new version, but is a alternate version of what we already have. Web needed to adapt to its mobile surroundings. Web 4.0 connects all devices in the real and virtual world in real-time.

    What is Web 5.0?

    • Web 5.0 is aimed at building an extra decentralized web that puts you in control of your data and identity.
    • Simply put, Web 5.0 is Web 2.0 plus Web 3.0 that will allow users to ‘own their identity’ on the Internet and ‘control their data’.
    • Both Web 3.0 and Web 5.0 envision an Internet without threat of censorship – from governments or big tech, and without fear of significant outages.

    What are the use cases for Web 5.0?

    There can be two use cases for how Web 5.0 will change things in the future.

    1. Control of identity: A digital wallet that securely manages user identity, data, and authorizations for external apps and connections.
    2. Control over own data: Say, we can grant any music app access to settings and preferences, enabling the app to take our personalized music experience across different music apps.

    Try this question from CSP 2022:

    With reference to Web 3.0, consider the following statements:

    1. Web 3.0 technology enables people to control their own data.
    2. In Web 3.0 world, there can be blockchain based social networks.,
    3. Web 3.0 is operated by users collectively rather than a corporation.

    Which of the statements given above are correct?

    (a) 1 and 2 only

    (b) 2 and 3 only

    (c) 1 and 3 only

    (d) 1, 2 and 3

    E-Vidhan System for Paperless Legislation

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: National e-Vidhan Application (NeVA)

    Mains level: Parliamentary efficiency

    A delegation of MLAs from Gujarat visited the UP Legislative Assembly to learn about the novel e-Vidhan system for paperless proceedings that has been recently adopted by the UP state assembly.

    E-Vidhan System

    • The National e-Vidhan Application (NeVA) is a system for digitising the legislative bodies of all Indian states and the Parliament through a single platform.
    • It includes a website and a mobile app.
    • The house proceedings, starred/unstarred questions and answers, committee reports etc. will be available on the portal.
    • Nagaland became the first state to implement NeVA, in March this year.

    Significance of NeVA

    • There has been a shift towards digitisation in recent years by the government.
    • NeVA aims for streamlining information related to various state assemblies, and to eliminate the use of paper in day-to-day functioning.
    • PM Modi mentioned the idea of “One Nation One Legislative Platform” in November 2021.
    • A digital platform not only gives the necessary technological boost to our parliamentary system, but also connects all the democratic units of the country.

    Has this been done elsewhere?

    • Himachal Pradesh’s Legislative Assembly implemented the pilot project of NeVA in 2014, where touch-screen devices replaced paper at the tables of the MLAs.
    • Though both Houses of Parliament have not gone fully digital yet, governments world over are heading towards embracing the digital mode.
    • In December last year, the Government of Dubai became the world’s first government to go 100 percent paperless.
    • It announced all procedures were completely digitised.
    • This, as per a government statement, would cut expenditure by USD 350 million and also save 14-million-man-hours.

    What are the challenges?

    • Access to devices and reliable internet and electricity was an issue particularly for legislators representing rural constituencies.
    • Lack of training and heightened concerns over security are some more recent issues in the road to digitization.

    Microplastics found in Antarctica

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Microplastics pollution

    Mains level: Not Much

    Scientists have found microplastics — plastic pieces much smaller than a grain of rice — in freshly fallen Antarctic snow for the first time.

    What are Microplastics?

    • Microplastics are tiny bits of various types of plastic found in the environment.
    • The name is used to differentiate them from “macroplastics” such as bottles and bags made of plastic.
    • There is no universal agreement on the size of microplastics. It defines microplastic as less than 5mm in length.
    • However, for the purposes of this study, since the authors were interested in measuring the quantities of plastic that can cross the membranes and diffuse into the body via the bloodstream.
    • Hence they agreed on an upper limit on the size of the particles as 0.0007 millimetre.

    Why in news?

    • Researchers have found microplastics in the snow samples from the Ross Ice Shelf in Antarctica.

    Threats posed by Microplastics

  • Nuclear Energy

    What is TVS-2M Nuclear Fuel?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: TVS-2M Nuclear Fuel

    Mains level: Not Much

    Russia has supplied the first batches of more reliable and cost-efficient nuclear fuel over the existing one, the TVS-2M nuclear fuel, to India for the Kudankulam Nuclear Power Plant (KNPP).

    What is TVS-2M Nuclear Fuel?

    • The TVS-2M FAs contain gadolinium-oxide which is mixed with U-235 enrichments.
    • The core does not contain BARs (Burnable Absorbers Rods).

    How are they prepared?

    • Once the uranium is enriched, it is ready to be converted into nuclear fuel.
    • At a nuclear fuel fabrication facility, the UF6, in solid form, is heated to gaseous form, and then the UF6 gas is chemically processed to form uranium dioxide (UO2) powder.
    • The powder is then compressed and formed into small ceramic fuel pellets.
    • The pellets are stacked and sealed into long metal tubes that are about 1 centimetre in diameter to form fuel rods.
    • The fuel rods are then bundled together to make up a fuel assembly.
    • Depending on the reactor type, each fuel assembly has about 179 to 264 fuel rods.
    • A typical reactor core holds 121 to 193 fuel assemblies.

    Benefits offered

    • TVS-2M fuel assemblies have a number of advantages making them more reliable and cost-efficient.
    • The new fuel has increased uranium capacity – one TVS-2M assembly contains 7.6% more fuel material as compared to UTVS.
    • Besides, the special feature of the Kudankulam fuel in particular is the new generation anti-debris filter ADF-2, efficiently protecting fuel assemblies.
    • Once the new TVS-2 M fuel is used in the next refuelling, the reactor will start operations with an 18-month fuel cycle.
    • It means the reactor, which has to be stopped for every 12 months for removing the spent fuel and inserting the fresh fuel bundles and allied maintenance, will have to be stopped for every 18 months.

    Back2Basics: India-Russia Energy Cooperation

    • The Soviet Union supplied India with nuclear reactors and fuel when India was denied technologies and was hit with sanctions from the West for its refusal to sign the nuclear non-proliferation treaty (NPT).
    • In 1988, the Soviet Union agreed, allegedly without an official deal, to build two nuclear reactors at Kudankulam in Tamil Nadu.  The deal was made official in 1992.
    • In 2000, Russia and India signed another secret MoU, to cooperate on “peaceful uses” of nuclear energy, and for Russia to supply India with low-enriched uranium fuel for the Tarapur reactor in Maharashtra.
    • In 2009, the two countries entered into a major nuclear deal, with Russia agreeing to install four nuclear reactors at Kudankulam in Tamil Nadu, and one in West Bengal.
    • Two units at Kudankulam are currently operational, and the third and fourth units are being prepared for installation.
    • Russia is also aiding with the ongoing construction of the fifth and sixth units.
