Current Affairs 5th April 2023 for UPSC Prelims Exam

Sodium Cyanide

Context: India has initiated an anti-dumping probe into imports of poisonous chemical, sodium cyanide from China, European Union, Japan and Korea following a complaint by domestic players.

About Sodium Cyanide

  • Sodium Cyanide is a toxic cyanide salt, sodium salt, and one-carbon compound that is used as an insecticide, a test reagent for the function of chemoreceptors, and in many industrial processes.
  • It is characterized as a white crystalline solid, colourless gas, or aqueous solution that is odourless or has a faint, bitter almond-like odour. Exposure occurs by inhalation, ingestion, or contact.
  • Production: It is produced by treating hydrogen cyanide with sodium hydroxide.
  • Utility: Sodium cyanide is used for extraction of gold and silver from their respective ores, manufacturing insecticides, dyes, pigments, and bulk drugs.

About Anti-Dumping duties

  • Dumping is when the goods are exported by a country to another country, at a price lower than the price it normally charges in its own home market.
  • Anti-dumping duty is a measure to rectify impacts, arising out of the dumping of goods and its trade distortive effect. The Finance ministry takes the final decision to impose duties.
  • The imposition of duties falls under the multilateral regime of World Trade Organization (WTO), which aims at ensuring fair trading practices and creating a level-playing field for domestic producers vis-a-vis foreign producers and exporters.
  • Imposition: The Directorate General of Trade Remedies (DGTR) examines whether domestic industries have been harmed by an increase in cheap imports and, if so, will recommend the imposition of anti-dumping duty on the imports.
  • Validity: Anti-dumping duty is valid for a period of five years from the date of imposition unless revoked earlier.
    • It can be extended for a further period of five years through a sunset or expiry review investigation.

Project 75 (I)

Context: Germany is expected to present a proposal to India for the sale of advanced conventional submarines through the government-to-government route.

About Project 75 (India) [P-75(I)]

  • It is an ambitious plan for the indigenous construction of six modern conventional submarines with contemporary equipment, weapons & sensors including Fuel-Cell based AIP (Air Independent Propulsion Plant), advanced torpedoes, modern missiles and state of the art countermeasure systems.

AIP Module

  • An AIP module acts as a force multiplier as it enables conventional submarines to remain submerged for a longer duration, thereby increasing their endurance and reducing chances of detection.
  • An indigenously developed AIP module is set to be installed on the Scorpene submarines as they go for refit from 2024 onwards.

Significance of P-75 (I)

  • P-75 (I) would provide a major boost to the indigenous design and construction capability of submarines in India.
  • It would bring the latest submarine design and technologies as part of the project.


  • It includes the indigenous construction of six diesel-electric attack submarines of Scorpene design.
  • The submarines are being constructed at Mazagon Dock Shipbuilders Limited (MDL) in Mumbai in collaboration with the Naval Group of France.

Asilomar Principles and Artificial General Intelligence (AGI)

Context: A group of AI experts have signed a letter of moratorium on developing advanced artificial intelligence (AI) systems, citing Asilomar AI Principles.

About Asilomar Principles

  • Asilomar AI Principles are a set of 23 guidelines for the research and development of artificial intelligence (AI).
  • They were laid out at the Beneficial AI 2017 conference hosted by Future of Life Institute (FLI).
  • These principles were developed by a group of AI researchers, robotics, technology experts and legal scholars from different institutions.

Artificial General Intelligence (AGI)

  • AGI refers to a theoretical type of machine intelligence that possesses human-like cognitive abilities.  AGI is also known as deep AI, strong AI, full AI, or general intelligent action.
  • AGI does not involve replicating or simulating processes, instead it focuses on training machines to understand humans to differentiate needs, emotions, beliefs, and thought processes.
  • Concerns with AGI
    • AGI poses serious risk of misuse, drastic accidents, and societal disruption. AGI can also threaten large number of jobs.

Context: Recently, a massive avalanche hit the Gangtok-Nathu La road near MS-15 (between Mile 13 and 17).

About Avalanches:

  • Avalanches are masses of snow, ice, and rocks that fall rapidly down a mountainside.
  • There are various kinds of avalanches, including rock avalanches (which consist of large segments of shattered rock), ice avalanches (which typically occur in the vicinity of a glacier), and debris avalanches (which contain a variety of unconsolidated materials, such as loose stones and soil).
  • The size of an avalanche can range from a small shifting of loose snow to the displacement of enormous slabs of snow.
  • In a slab avalanche, the mass of descending snow may reach a speed of 130 km (80 miles) per hour and is capable of destroying forests and small villages in its path.
  • Some important types of Avalanches
    • Slab avalanches: A slab avalanche occurs when the weak layer lies lower down in a snowpack.
    • Loose snow avalanches: Loose snow avalanches happen when poorly bonded surface snow slides downhill under its own weight.
    • Cornice Fall Avalanches: Cornices are overhanging masses of wind-deposited snow that protrude from sharp terrain features like ridges or peaks.
    • Powder Snow Avalanches: Powder Snow Avalanches are a mix of the other forms, Loose Snow and Slab.
    • Glide Avalanches: Glide occurs when the entire snowpack slowly slides as a unit on the ground, similar to a glacier.
    • Slush Avalanches: slush avalanche occurs in impermeable permafrost soil, which allows water to pool up, and occurs during rapid saturation of a thin, weak snowpack.
  • Causes of Avalanches: Heavy Snowfall, Wind Direction, Vibration or Movement, Layers of Snow, Steep Slopes, Warm Temperature, Deforestation, Natural Causes (i.e., Earthquakes), Human Activity.

Nathu La Pass:

  • Nathu La is a mountain pass in the Himalayas connecting Sikkim with Chumbi Valley of the Tibetan Plateau in China.
  • It is located ahead of Muguthang or Cho Lhamu (source of River Teesta).
  • It is one of the three open trading border posts between China and India; the others being Shipki La in Himachal Pradesh and Lipulekh at the trisection point of Uttarakhand–India, Nepal and China.
  • Nathu means ‘listening ears’, and La means ‘pass’.
  • The other passes located in the state of Sikkim are Jelep La Pass, Donkia Pass, Chiwabhanjang Pass.

Open-Source Software (OSS)

Context: Owner and CEO of Twitter (Elon Musk) has partly delivered on his promise of making Twitter’s algorithm open source.

About Open-Source Software (OSS):

  • OSS is software that is distributed with its source code, making it available for use, modification, and distribution with its original rights.
    • Source code is the code computer programmers manipulate to control how a program or application behaves.
  • OSS typically includes a license that allows programmers to modify the software to best fit their needs and control how the software can be distributed.
  • The idea of making source code freely available originated in 1983 from an ideological movement informally founded by Richard Stallman, a programmer at MIT.
  • Examples of Linux, Mozilla Firefox, VLC media player, SugarCRM, etc.
  • Benefits of OSS:
    • The Open-source model is based on a more decentralized model of production, thus helps in reducing the monopoly of large commercial firms which are primarily centralized model of production for revenue maximization.
    • OSS will help in reducing government’s cost of procurement of commercial software’s.
    • OSS can be modified and customized to suit spatial and temporal diversities.

Twitter’s Algorithm

  • It is a set of rules that enables the platform to deliver content based on users’ interests and preferences.
  • Content flows into a user’s timeline through two channels.
    • One pipeline channels content posted by people that the user follows and the other is filled with posts flowing from accounts that could potentially interest the user.
