Answer:

C. V. Raman image

  • Raman spectroscopy, named after Indian physicist Sir C. V. Raman.
  • It is a spectroscopic technique used:
    • to observe vibrational, rotational, and other low-frequency modes in a system
    • to provide information on molecular vibrations and crystal structures.
  • It plays an important role in both R&D and QA/QC in a variety of industries and academic fields such as semiconductors, polymers, pharmaceuticals, batteries, life sciences and more.

Usage:

  • Identifying the unknown substance and polymers,
  • Tracking changes in molecular structures,
  • Tracking a change in crystallinity,
  • Evaluating the magnitude of residual stress,
  • Assessing the direction of orientation of molecules.
  • Provide a structural fingerprint by which molecules can be identified.

The advanced types of Raman spectroscopy include surface-enhanced Raman, resonance Raman, tip-enhanced Raman, polarized Raman, stimulated Raman (analogous to stimulated emission), transmission Raman, spatially offset Raman, and hyper Raman.

About Kaleshwaram Irrigation Project:

ias toppers Kaleshwaram Lift Irrigation Project

  • It is a dream project of present Telengana government.
  • The Kaleshwaram project is an off-shoot of the original Pranahitha-Chevella Lift Irrigation Scheme taken up by the Congress government in 2007 when Andhra Pradesh was not divided.

Uniqueness of the project:

  • It is claimed to be the costliest irrigation project to be taken up by any State till date with an estimated cost of ₹80,500 crore.
  • It will be providing irrigation facility to one crore acres of land under all projects/tanks.
  • The project including the longest tunnel to carry water in Asia, running up to 81 km, between the Yellampally barrage and the Mallannasagar reservoir.
  • The project would also utilise the highest capacity pumps, up to 139 MW, in the country to lift water.
  • It will make availability of water round-the-year and eradicating drought permanently.

Answer:

  • Initial coin offering (ICO) is an unregulated and controversial means of crowdfunding via use of cryptocurrency, which can be a source of capital for start-up companies.
  • It means that someone offers investors some units of a new cryptocurrency or crypto-token in exchange against cryptocurrencies like Bitcoin or Ethereum.

Usage:

  • Since 2013 ICOs are often used to fund the development of new cryptocurrencies.
  • The pre-created token can be easily sold and traded on all cryptocurrency exchanges if there is demand for them.
  • ICOs can be used for a wide range of activities, ranging from corporate finance to charitable fundraising to outright fraud.
  • ICO enables every individual and every company to easily release freely tradable tokens to raise funds.
  • It could be used to completely reconstruct the financial system of shares, securities and so on. It decentralized not just money, but stock creation and trade.

Significance:

  • ICO has become a tool that could revolutionize not just currency but the whole financial system. ICO token could become the securities and shares of tomorrow.
  • The first cryptocurrency distributed by an ICO was Ripple then several other cryptocurrencies have been funded with ICO like Bitcoin, NEXT, Mastercoin, Lisk, prominent however is Ethereum.
  • Gnosis, EtherEx and Akasha are the hot future ICO’s.
  • They are very high risk and speculative investments, are scams in some cases, and often offer no protections for investors.
  • The potential of this trend is immense.
  • The legal state of ICO is mostly undefined. Ideally, the token is sold not as a financial asset but as a digital good like many other things. This is why ICO is often called “crowd sale”.

Balfour Declaration iastoppers

Why in news:

  • The year 2017 marks one hundred years since the Balfour Declaration was issued.
  • The British government recently stated that it should have called for protection of the Palestinian Arabs’ political rights.

The Impact:

  • A century after Balfour, the Palestinians continue to be denied their basic rights to peace and security.
  • It set in motion the process which led to the displacement and dispossession of millions of Palestinians over the course of ten decades.
  • The declaration had two indirect consequences, the emergence of a Jewish state and a chronic state of conflict between Arabs and Jews throughout the Middle East.
  • It led to the creation of Mandatory Palestine, which later became Israel and the Palestinian territories.
  • It widened into the regional Arab–Israeli conflict, often referred to as the world’s “most intractable conflict”.
  • There are now more than 5 million Palestinian refugees facing poverty and insecurity across the occupied Palestinian territories, Lebanon and Jordan, and in Syria.
  • The Gaza Strip and the West Bank have been under military occupation for 50 years; the West Bank is being colonised by illegal settlers, while the Gaza Strip languishes after a decade of siege.
