Current Affairs Quiz - April, 2019

Notes:
Former world champion, Viktor Axelsen of Denmark has won the men’s singles title at the 2019 Yonex-Sunrise India Open badminton tournament on March 31. In the final, he defeated Kidambi Srikanth by 7-21, 20-22 in New Delhi. This was Srikanth’s fourth defeat to Axelsen in five encounters since March 2017. And also, it was Srikanth’s first final in a BWF world tour event in 17 months. He had last won a title at the 2017 French Open.

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:
The United States has approved the sale of 24 multi-role MH-60 Romeo Seahawk helicopters to India under its Foreign Military Sales (FMS) program at an estimated cost of $2.4 billion. The multi-mission helicopters can detect, track and attack submarines and surface ships at sea. They are designed to operate from frigates, destroyers, cruisers and aircraft carriers. Thus, these are considered the world’s most advanced maritime helicopters. The choppers will provide the Indian defence forces with the capability to perform anti-surface and anti-submarine warfare missions along with the ability to perform secondary missions including vertical replenishment, search and rescue, and communications relay. Hence, the Lockheed Martin-built helicopters would replace India’s aging fleet of British-made Sea King helicopters. The proposed sale will support US foreign policy & national security by helping to strengthen the US-Indian strategic relationship and to improve the security of a major defensive partner.

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:
On March 28, President Ram Nath Kovind became the first-ever Indian President to visit Bolivia. Here, President Evo Morales Ayma conferred the highest State Honour of Bolivia – Condor de los Andes en el Grado de Gran Collar – on President Kovind. Both the countries have agreed to facilitate Bolivian supplies of lithium Carbonate to India and foster joint ventures for Lithium battery / cell production plants in India. This move will make Bolivia, which is known to have one-fourth of the world’s lithium reserves, one of the major provider of metal for India’s e-mobility and e-storage needs. To mark the 150th Birth Anniversary of Mahatma Gandhi, India offered two busts of Gandhiji to Bolivia. The Bolivian side accepted the offer and is likely to place the busts in its capital La Paz and its largest city Santa Cruz. This South American nation has also joined the International Solar Alliance (ISA) by signing the framework agreement on ISA. In a total, India and Bolivia have signed 8 MoUs in various fields of mining, space, traditional medicine during President’s Kovid three day visit to the country.

Notes:
The International Day for Mine Awareness and Assistance in Mine Action is observed every year on April 4 to raise awareness about landmines, explosive remnants of war, and progress toward their eradication. The 2019 Theme is “United Nations Promotes SDGs – Safe Ground – Safe Home”.

Notes:
On April 5, Vice President M. Venkaiah Naidu inaugurated the National Cardiology Conference 2019 at Sanjay Gandhi Post Graduate Institute of medical sciences in Lucknow, Uttar Pradesh. The 3-day conference will be organized by Dept of Cardiology in which leading national and international experts from Europe, USA, Japan, Singapore South Korea, Indonesia and Australia will deliberate on the latest topics of Interventional cardiology and cutting edge technology. The conference being held for the first time in Uttar Pradesh offers an opportunity to showcase newer innovations in Cardiology that can help deliver cost-effective cardiology care to patients.

Notes:
Vipin Anand Monday has recently taken charge as the new Managing Director (MD) of the Life Insurance Corporation of India (LIC).

Notes:
The National Maritime Day (NMD) of India is celebrated every year on April 5 to spread awareness in supporting intercontinental commerce and the global economy. On this day, in 1919, navigation history was created when SS Loyalty, the first ship of the Scindia Steam Navigation Company, journeyed to the United Kingdom. It was a crucial step for Indian shipping history when sea routes were controlled by the British. The theme of the 56th edition of the NMD 2019 is “Indian Ocean-An Ocean of opportunity”. According to the Directorate General of Shipping, India now has 43 shipping companies owning 1,401 ships with a combined 12.69 million gross tonnage’ as of December 2018.
