  1. Snapdragon Processor

    ➖Suite of system on a chip (SoC) semiconductor products for mobile devices.

    ➖Snapdragon semiconductors are embedded in devices of various systems, including Android, Windows Phone and netbooks.

    ➖They are also used in cars, wearable devices and other devices

    ➖In addition to the processors, the Snapdragon line includes modems, wi-fi chips and mobile charging products.

  2. Difference between OLED & AMOLED
    🔹OLED display offers a high level of control over pixels and hence can be turned off completely, which further results in excellent contrast ratio as compared to the AMOLED displays and less power consumption.

    🔹AMOLED has faster refresh rates than OLEDs. Also, they offer great artificial contrast ratio as each pixel transmits light but consumes more power than OLEDs.

    🔹OLED displays are comparatively much thinner as compared to the LCDs. Hence, it provides more efficient and bright displays.

    🔹OLED provides support for large display sizes as compared to the traditional LCDs.

    🔹AMOLEDs removes the limitation of display sizes. It can be fitted into any display size.

  3. OLED Display Technology
    🔹Provides a good quality display.


    🔹Much brighter than LEDs.

    🔹Do not require backlighting.

    🔹Much faster response time as compared to the traditional LCDs.

    🔹Lifespan is much shorter as compared to LCD, LED and PDP display technologies.

    🔹Variation in color balance.

    🔹Does not provide resistance against water. Water can easily damage the OLED displays.

    🔹In this technology, each pixel transmits its own light

    🔹Display much deeper blacks as compared to the AMOLED displays.

  4. AMOLED Display Technology
    🔹Active Matrix Organic Light Emitting Diode

    🔹Based on the active matrix system, having a thin film transistor (TFT) to control the flow of current in each pixel

    🔹Offers no limitation on the size of the display

    🔹Power consumption of AMOLED is much less than other display technologies

    🔹Thinner, lighter and flexible than any other display technology like LED, LCD technology

    🔹Storage capacitors are used to maintain the pixel states

    🔹You cannot see the screen in AMOLED display under direct sunlight

  5. Particularly Vulnerable Tribal Groups in Andaman & Nicobar

    ➖Great Andamanese (in Strait Island),

    ➖Shompens (in the Greater Nicobar Islands)

  6. The Amundsen Sea region in West Antarctica and Wilkes Land in East Antarctica are the two regions most sensitive to warming ocean temperatures and changing currents, and will continue to lose large amounts of ice.
  7. The Rio Grande river separates Mexico and Texas, United States
  8. Rivers make up 23 % of international borders, 17 % of the world’s state and provincial borders and 12 % of all county-level local borders, according to the Global Subnational River-Borders database.
  9. Hong Kong International Convention
    🔹Convention for the safe and environmentally sound recycling of ships

    🔹Mulitateral convention adopted in 2009, which has not entered into force

    🔹Overseen by the International Maritime Organization (IMO)

    🔹On 28 November, India, ratified the convention

    ➖Bangladesh, China, India, Pakistan and Turkey are world’s the top five shipbreaking countries, accounting for more than 98 per cent of the global shipbreaking by gross tonnage.

    ➖India handles around 25% share of the world’s ship recycling industry. The government plans to nearly double this by 2024
