Current Affairs Quiz - April, 2019

Notes:
On April 1, ISRO has successfully launched India’s latest EMISAT defence satellite from the Sriharikota spaceport. In today’s mission, the rocket PSLV-C45 flew in a new configuration called “QL”. In this configuration, the rocket is fitted with four longer versions of strap-on motors that provide the vehicle the required additional thrust. Earlier, the rocket used to be in “XL” version with six strap-on motors or two or with no strap-on motors known as core alone configuration. The PSLV-C45 successfully injected EMISAT in a 748-km sun-synchronous polar orbit and 28 international customer satellites in a 504-km orbit. Of these, 24 are from the US, two from Lithuania, and one each from Spain and Switzerland. EMISAT is a satellite built around ISRO’s Mini Satellite-2 (IMS-2) bus weighing about 436 kg. The satellite is intended for electromagnetic spectrum measurement.

Notes:
The 13th edition of Earth Hour 2019 was observed on March 30 with theme “#Connect2Earth” to encourage people across the world to turn off non-essential electric lights for one hour from 8:30 to 9:30 p.m. It calls for greater awareness and more sparing use of resources, especially fossil fuels that produce carbon gases and lead to global warming. On this day, the World Wide Fund (WWF) for Nature-India made an appeal to citizens to join the Earth Hour 2019 to inspire millions across the country to shift to more sustainable practices and minimize negative impacts on the planet.

Notes:
The Hump-backed Mahseer, also known as ‘Tor remadevii’ in scientific terms, is a critically endangered species as per the International Union for Conservation of Nature (IUCN). This iconic and highly-valued freshwater fish, termed as the ‘tiger of the water’, inhabits the Cauvery river basin, including Kerala’s Pambar, Kabini and Bhavani rivers. The fish earns its megafauna status by reaching up to a measurement of 1.5m and a weight of 55 kg. Its endangered title also accompanies five other species, including two wild orchids, the Arabian scad, and two wild coffee species exclusive to a few locales in the Western Ghats.

Notes:
The Hongkou district of Shanghai has recently claimed to have the world’s first district with 5G coverage and a broadband gigabit network. It conducted trial runs of the 5G network, backed by telecom services provider China Mobile. Shanghai also aims to build over 10,000 5G base stations by the end of this year and the number of 5G base stations could cross 30,000 in 2021. 5G is the next generation of cellular technology with download speed 10 to 100 times faster than the 4G LTE networks.

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:
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 book titled “Kundan: Saigal’s Life & Music” has been penned by Sharad Dutt, documentary filmmaker and former DDG of Doordarshan. The genius of legendary singer K L Saigal, his timeless compositions and the golden era of Indian cinema have been brought alive in a book. The book has been trans-created in English by Jyoti Sabharwal of Stellar Publishers and will be released on April 4, the 115th birth anniversary of Saigal. Some of Saigal’s all time hits are ‘Jab dil hi toot gaya’, ‘Ek bangla bane nyara’, ‘Dukhake din aab bitat nahin’, ‘Duniyamen hun duniyaka talabgaar nahin hun’ and ‘So ja rajkumari so ja’.

Notes:
The State of the Global Air 2019 report has recently released by the Boston-based Health Effects Institute (HEI). The report revealed that 1.2 million Indians lost their lives due to exposure to unsafe air in 2017. Now, in India, air pollution is the third-highest cause of death among all health risks, ranking just above smoking. This is a combined effect of outdoor fine particles PM2.5, ozone and household (indoor) air pollution. In 2017, exposure to PM 2.5 pollution was found to be the third leading risk factor globally for Type 2 diabetes-related deaths and disability after high blood sugar and excessive body weight. Due to this combined exposure South Asians including Indians are dying early — their life expectancy has reduced by over 2.6 years. In India, early deaths are linked to respiratory diseases, heart disease, stroke, lung cancer, and diabetes that are influenced by air pollution.

Notes:
In India, the NuGen Mobility Summit 2019 will be organized by the International Centre for Automotive Technology (ICAT) at Manesar, NCR, from 27th to 29th November 2019. The purpose of the Summit is to share new ideas, learnings, global experiences, innovations and future technology trends for faster adoption, assimilation and development of advanced automotive technologies for a smarter and greener future. This event will help in building a platform for bringing together all stakeholders in the automotive industry to understand global advancements in technologies. More than 2500 participants and over 250 exhibitors are expected to take part in the Summit.

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).
