Current Affairs Quiz - April, 2019

Notes:
The Government of India (GoI) has constituted a tribunal to adjudicate if there exists sufficient cause to ban the Jamaat-e-Islami Jammu and Kashmir (JeL) and the Jammu and Kashmir Liberation Front-Yasin Malik (JKLF-Y) faction. The tribunal will be headed by Justice Chander Shekhar of the Delhi High Court. The decision has been taken by the Union Home Ministry exercising the powers conferred under the Unlawful Activities (Prevention) Act of 1967. The JeI and the JKLF-Y were declared as unlawful associations on February 28 and March 22 respectively.

Notes:
China has successfully launched the first of its new-generation ‘Tianlian II-01’ data relay satellite into orbit by a Long March-3B carrier rocket from the Xichang Satellite Launch Centre in southwest Sichuan Province. This is the first of China’s second-generation data-tracking and relay satellites. It will provide services like data relay, measurement and control, and transmission to manned spacecraft, satellites, carrier rockets and non-spacecraft users. The Tianlian II network will be markedly more advanced in mission planning, system management and operations than the first-generation network composed of Tianlian I satellites. The satellite is developed by the China Academy of Space Technology under the China Aerospace Science and Technology Corporation.

Notes:
The World Autism Awareness Day (WAAD) is observed every year to raise public awareness of Autism Spectrum Disorder (ASD). Autism is a brain disorder that typically affects a person’s ability to communicate with others. It generally begins in childhood and last through adulthood. The day highlights the need to help and improve the quality of life of those with autism so that they can lead full and meaningful lives as an integral part of society. The 2019 theme “Assistive Technologies, Active Participation” , underscores the importance of affordable assistive technologies to support people with autism to live independent lives and, indeed, to exercise their basic human rights.

Notes:
Researchers led by Kavli Institute for the Physics and Mathematics of the Universe in Japan has put a theory speculated by the late Stephen Hawking to its most rigorous test to date, and their results have ruled out the possibility that primordial black holes smaller than a tenth of a millimeter make up most of dark matter. They used the gravitational lensing effect to look for primordial black holes between Earth and the Andromeda galaxy. However, gravitational lensing effects are very rare events because it requires a star in the Andromeda galaxy, a primordial black hole acting as the gravitational lens, and an observer on Earth to be exactly in line with one another. In order to maximise the chances of capturing an event, the researchers used the Hyper Suprime-Cam digital camera on the Subaru telescope in Hawaii, which can capture the whole image of the Andromeda galaxy in one shot. Taking into account how fast primordial black holes are expected to move in interstellar space, the team took multiple images to be able to catch the flicker of a star as it brightens for a period of a few minutes to hours due to gravitational lensing. The team’s results showed primordial black holes can contribute no more than 0.1% of all dark matter mass. Therefore, it is unlikely the theory is true.

Notes:
South Korea will launch the world’s first fully-fledged 5G mobile networks on 5th April 2019. Hyper-wired South Korea has a reputation for technical prowess, and Seoul has made the 5G rollout a priority as it seeks to stimulate stuttering economic growth. The superfast communications heralded by fifth-generation wireless technology will bring smartphones near-instantaneous connectivity – 20 times faster than the existing 4G. It is crucial for the future development of devices ranging from self-driving vehicles that send data traffic to one another in real time, industrial robots, drones and other elements of the Internet of Things. 5G’s hyper speed can connect one million devices within a one square kilometre zone simultaneously. Until now, no mobile networks have offered nationwide 5G access. Japan is expected to roll out a limited deployment in 2019 before full services start in time for 2020 Tokyo Olympics.

Notes:
According to a new collaborative study by the Queen’s University Belfast and Aberystwyth University in the UK, the sun’s magnetic field is ten times stronger than previously thought. Using the Swedish one-metre Solar Telescope at Roque de los Muchachos Observatory, in the Canary Islands, David Kuridze studied a particularly strong solar flare which erupted near the surface of the Sun on September 10, 2017. A combination of favourable conditions and an element of luck enabled the team to determine the strength of the flare’s magnetic field with unprecedented accuracy. The researchers believe the findings have the potential to change our understanding of the processes that happen in the Sun’s immediate atmosphere. The study found that the sun’s corona extends millions of kilometres above the surface, measuring 1,400,000 kilometres across — 109 times larger than Earth — and 150,000,000 km from Earth. Solar flares appear as bright flashes and occur when magnetic energy that has built up in the solar atmosphere is suddenly released. These solar flares can lead to storms which, if they hit Earth, form the northern lights — the Aurora Borealis. They can also disrupt communications satellites and GPS systems.

Notes:
Prof. Vikram Patel, a psychiatrist and professor of global health at Harvard Medical School, has won the prestigious 2019 John Dirks Canada Gairdner Global Health Award. Mr. Patel has led research generating knowledge on the burden and determinants of mental health problems in low and middle-income countries and pioneered approaches which utilise community resources for the prevention and treatment of mental health problems in India with global impact. Laureates receive a $100,000 cash honorarium and will be formally presented with their awards on October 24, 2019 at the annual Canada Gairdner Awards Gala in Toronto.

Notes:
The Reserve Bank of India (RBI) has cut its repo rate under Liquidity Adjustment Facility (LAF) by 25 basis points to 6.0% in its first bi-monthly policy statement of the current financial year FY20, with immediate effect. The move will cheer markets and investors and is the second consecutive rate cut by the RBI. It has also maintained the policy stance neutral and lowered the retail inflation and GDP forecasts. This is the second consecutive rate cut from RBI under new Governor Shaktikanta Das, after a rate cut in February 2019. Consequently, the reverse repo rate under the LAF stands adjusted to 5.75%, and the Marginal Standing Facility (MSF) rate and the Bank Rate to 6.25%. These decisions are in consonance with the objective of achieving the medium-term target for consumer price index (CPI) inflation of 4% within a band of plus or minus 2% while supporting growth.

Notes:
The Indian Army has constructed the 260 feet long cable-suspension bridge ‘Maitri Bridge’ over Indus river at Choglamsar village in Leh in a record time of 40 days. It is the longest suspension bridge over the river and is built by combat engineers of the ‘Sahas aur Yogyata’ regiment of the Indian Army’s ‘Fire and Fury Corps’. The name of the bridge, “Maitri”, is meant to symbolise the amity and solidarity between soldiers and locals. The bridge is expected to improve connectivity in remote regions of Leh and Ladakh. It will connect the remote areas of Choglamsar, Stok and Chuchot, which are said to be the largest villages in the region.

Notes:
On April 5, Telecom giant Samsung Electronics released the Galaxy S10 5G in South Korea. It is the world’s first available smartphone with built-in fifth-generation communications. Earlier, South Korea became the first country to roll out a super-fast 5G mobile network nationwide, which allows users to download entire movies almost instantaneously. Three South Korean carriers – SK Telecom, KT and LG Uplus – — held launch events across Seoul for the Galaxy S10, whose base version costs 1.39 million won ($1,200). Thus, commercializing 5G gives South Korea the chance to build around the technology, which is crucial for the future development of devices such as autonomous vehicles and the Internet of Things (IoT).
