    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.

    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.

  • 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.

    Presidential polls scheduled for July 18

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Election of the President

    Mains level: Read the attached story

    The presidential polls are expected to be held in July to decide on the successor of President Ram Nath Kovind, who will complete his term on July 24, 2022.

    The President of India

    • The President of India is recognised as the first citizen of the country and the head of the state.
    • The elected President of India is a part of the Union Executive along with several other members of the parliament including the Prime Minister, Attorney-General of India and the Vice – president.

    Electing the President

    • The provisions of the election of the President are laid down in Article 54 of the Constitution of India.
    • The Presidential and Vice-Presidential Election Act 1952 led to the establishment of this Constitutional provision.

    Qualifications to become the President of India

    The qualification of be the President of India are given below:

    • He/ She must be an Indian citizen
    • A person must have completed the age of 35.
    • A person must be qualified for election as a member of the House of the People.
    • Must not hold a government (central or state) office of profit
    • A person is eligible for election as President if he/she is holding the office of President or Vice-President.

    Actual course of election

    • The President of India is elected indirectly by an Electoral College following the system of proportional representation utilizing a single transferable vote system and secret ballots.
    • MPs and MLAs vote based on parity and uniformity values.

    Electoral College composition-

    (1) Legislative Assemblies of the States:

    • According to the provision of Article 333, every state’s Legislative Assembly must consist of not less than 60 members but not more than 500 members.

    (2) Council of States:

    • 12 members are nominated by the President of India based on skills or knowledge in literature, arts, science, and social service to act as the members of the Council of States.
    • In total, 238 represent act as representatives from both the States and Union Territories.

    (2) House of the People:

    • The composition of the House of People consists of 530 members (no exceeding) from the state territorial constituencies.
    • They are elected through direct election.
    • The President further elects 20 more members (no exceeding) from the Union Territories.

    Uniformity in the scale of representation of states

    To maintain the proportionality between the values of the votes, the following formula is used:

    Value of vote of an MLA= total no. of the population of the particular state/ number of elected MLAs of that state divided by 1000.

    Single vote system-

    • During the presidential election, one voter can cast only one vote.
    • While the MLAs vote may vary state to state, the MPs vote always remain constant.

    MPs and MLAs vote balance-

    • The number of the total value of the MPs votes must equal the total value of the MLAs to maintain the State and the Union balance.

    Quotas:

    • The candidate reaching the winning quota or exceeding it is the winner.
    • The formula sued is ‘Winning quota total number of poll/ no.of seats + 1’.

    Voters’ preference:

    • During the presidential election, the voter casts his vote in favor of his first preferred candidate.
    • However, in case the first preference candidate does not touch the winning quota, the vote automatically goes to the second preference.
    • The first preferred candidate with the lowest vote is eliminated and the votes in his/her favor are transferred to the remaining candidates.

    Why need Proportional representation?

    • The President of India is elected through proportional representation using the means of the single transferable vote (Article 55(3)).
    • It allows the independent candidates and minority parties to have the chance of representation.
    • It allows the practice of coalition with many voters under one government.
    • This system ensures that candidates who are elected don’t represent the majority of the electorate’s opinion.

    Why is President indirectly elected?

    If Presidents were to be elected directly, it would become very complicated.

    • It would, in fact, be a disaster because the public doesn’t have the absolute clarity of how the president-ship runs or if the candidate fits the profile of a president.
    • Another reason why the direct election system isn’t favorable is that the candidate running for the president’s profile will have to campaign around the country with the aid of a political party.
    • And, this will result in a massive political instability.
    • Moreover, it would be difficult and impossible for the government to hand out election machinery (given the vast population of India).
    • This will cost the government financially, and may end up affecting the economy as well.
    • The indirect election system is a respectable system for the First Man of India (rightly deserving).
    • The system/method of indirect electing of the president also allows the states to maintain neutrality and minimize hostility.
