Current Affairs Quiz - April, 2019

Notes:

It is Swiss player’s 28th Masters title and the 101st overall for a player who has won 20 Grand Slam singles titles.

Notes:
Using platinum nanocatalyst, a two-member team at the IIT Madras has successfully converted petroleum waste-product toluene into benzoic acid. Benzoic acid is used as a food preservative (E210) and medicine for fungal/bacterial infection. Toluene is converted into benzoic acid through selective and controlled oxidation in the presence of a catalyst — binaphthyl-stabilised platinum nanoparticles (Pt-BNP). Generally, organic reactions are carried out using organic solvents, which makes it expensive and also generates toxic waste. So, the team led by G. Sekar used water as solvent to make it environment-friendly. Also, a green oxidant (70% aqueous tert-butyl hydroperoxide or TBHP) is used for converting toluene into benzoic acid. When toluene is oxidised, it gives four products. But, the team used catalyst that they developed and then only benzoic acid is produced. No alcohol, aldehyde or ester is produced. The yield of benzoic acid varied from 68-96% depending on whether the toluene used is electron-deficient or electron-rich.

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:
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:
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:
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:
Asian Development Bank (ADB) has recently released its flagship publication Asian Development Outlook 2019. In its report, ADB has lowered India’s growth by 40 basis points to 7.2% in fiscal year 2019-20. Still, it will be fastest growing economy in the world. The report mentioned that recent policy measures by the Government of India (GoI) to improve the investment climate and boost private consumption and investment will help India to lift economic growth in the next two fiscal years. The growth rate in FY 2020-21 is likely to be 7.3%. India’s growth slowed from 7.2% in fiscal 2017 to 7% in 2018, with weaker agricultural output and consumption growth curtailed by higher global oil prices and lower government expenditure. The report added that sub-region wise, southeast Asia will sustain growth at close to 5% this year and the next one.

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:
In a setback to the ruling Pinarayi Vijayan government, a 49-page report submitted by an Amicus curiae to the Kerala High Court (KHC) on April 3 recommended a judicial probe into the cause of the worst-ever floods to hit the state in August 2018 after it found that faulty dam management led to the flooding. In a report, amicus curiae Jacob P. Alex said that none of the 79 dams in the State were operated or used for the purpose of flood control and moderation, despite the obligation to utilise them for flood control as per the stipulations under the National Water Policy, National Disaster Management Authority guidelines on flood and RTIO (real-time integrated operation). It seemed that high reservoir storage and sudden release of water had resulted in worsening the floods. Various alerts (blue/orange/red) were issued not in accordance with the EAP (Emergency Action Plan) guidelines. No proper follow-up action and effective precautionary steps, especially for evacuating people and accommodating them in safe locations, were taken after the issue of red alert. Hence, this was a matter to be inquired into.
