Current Affairs Quiz - April, 2019

Notes:
The scientists at the University of Wisconsin-Madison in the US have developed a novel sensor that can be used in smartphone-sized devices to detect dangerous chemicals based on a unique fingerprint of absorbed and emitted light. Devices called spectrometers are light-splitting instruments that have long been both bulky and expensive, preventing their use outside the lab. However, researchers have now developed a spectrometer so small and simple that it could integrate with the camera of a typical cellphone without sacrificing accuracy. The device also has an advanced capability called hyperspectral imaging, which collects information about each individual pixel in an image to identify materials or detect specific objects amidst a complicated background. Hyperspectral sensing could be used to detect seams of valuable minerals within rock faces or to identify specific plants in a highly vegetated area.

The report on ‘Political Leaders Position and Action on Air Quality in India 2014-2019’ has recently released by a Delhi-based environment body – Climate Trends. As per report, Uttar Pradesh’s Kanpur has been ranked 1st on the WHO’s list of 15 most polluted cities. Faridabad (Haryana) stood at 2nd position, followed by Varanasi (UP), which is the Lok Sabha constituency of Prime Minister Narendra Modi. The report claimed that the situation in Varanasi is deteriorating as its MP has focused on beautification and infrastructure. The Air Quality index (AQI) in Varanasi reached an alarming 490 in 2017 and 384 — very poor category — in December 2018. The report also noted that MPs of Lucknow and Kanpur — Home Minister Rajnath Singh and senior BJP leader Murli Manohar Joshi respectively — have mostly been silent on the issue of air pollution in their respective constituencies. Gaya and Patna in Bihar are 4th and 5th on the list, while Delhi is 6th and Uttar Pradesh capital Lucknow is 7th. Cities of Agra, Muzaffarpur, Srinagar, Gurugram, Jaipur, Patiala and Jodhpur are also on the WHO list of most polluted cities.

Notes:
On 13th April 2019, the nation paid homage to the martyrs of the Jallianwala Bagh massacre on the centenary of the incident. On this day in 1919, hundreds of innocent Indians were killed by troops under British Brigadier-General Reginald Dyer, during a peaceful meeting on Baisakhi at the park in Amritsar, Punjab. Here, the civilians had assembled for a peaceful protest to condemn the arrest and deportation of two national leaders, Satya Pal and Saifuddin Kitchlew. The massacre is one of the darkest chapters of India’s freedom struggle against the British occupation. The official death toll by the British government was put at 379, but Indian figures put the toll at closer to 1,000. Even after 100 years, the British government has only regretted the massacre but stopped short of apologizing for the killing of so many innocent people.

Notes:
The scientists at University of Edinburgh have discovered a new state of physical matter – which allows atoms to exist as both solid and liquid at the same time. Until now, atoms in physical matter were understood to exist typically in one of three states — solid, liquid or gas. An international team of physicists have found that some elements can take on the properties of both solid and liquid states, when subjected to extreme conditions. They used Artificial Intelligence (AI) to simulate what would happen if potassium was subject to huge pressure — between about 200,000 and 400,000 times atmospheric pressure — and heat — between 400 to 800 Kelvin (260 to 980 degrees Fahrenheit). The study found that under these conditions potassium atoms entered what is known as a chain-melted state, where one of the two lattices — the “guest” part — dissolved into liquid, while the “host” part remained solid. They found that more than half a dozen other elements, including sodium and bismuth, were able to reach the state if they were put into the right environments.

It is recognized by 136 UN members and since 2012 has a status of a non-member observer state in the United Nations – which implies recognition of statehood. It is a member of the Arab League, Organisation of Islamic Cooperation, G77, and the International Olympic Committee (IOC) and other international bodies.

Notes:
The International Day of Human Space Flight is observed every year on April 12 to mark the beginning of the space era for mankind, reaffirming the important contribution of space science and technology in achieving sustainable development goals and increasing the well-being of States and peoples, as well as ensuring the realization of their aspiration to maintain outer space for peaceful purposes. On 12th April 1961 the first human space flight was carried out by Yuri Gagarin, a Soviet citizen. This historic event opened the way for space exploration for the benefit of all humanity.

Notes:
In Bangladesh, the historic Mujibnagar has recently celebrated on April 17, 2019. The day marks the oath taking ceremony of Bangladesh’s first government in 1971 at Baidyanathtala in Meherpur. On this day in 1971, senior leaders of the liberation movement of Bangladesh had assembled at Baidyanathtala to form the provisional government of independent Bangladesh. Bangabandhu Sheikh Mujibur Rahman was declared the President in absentia as he was arrested and flown to Pakistan after the Pakistan military crackdown on the then ‘East Pakistan’ on the night of March 25, 1971. The day is being observed by political parties and social and cultural organisations through various programs across Bangladesh.
