Current Affairs Quiz - April, 2019

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:
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:
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:
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:
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:
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:
Phayeng Village of Manipur has been tagged as the India’s first carbon-positive settlement. As part of the carbon-positive village project, Phayeng will receive a grant of Rs10 crore in phases to facilitate afforestation in the catchment of river Maklang that flows along the village. The fund will also be utilised for creation of water bodies, introduction of climate change-resilient varieties of crops, installing solar lights, for setting up a community piggery and poultry farm, an eco-resort, replacing firewood in kitchen with cooking stoves and an indigenous knowledge centre in the village. A village is given the Carbon-Positive Tag if it sequesters more carbon than it emits, slowing the accumulation of greenhouse gases and mitigating the effects of climate change. Phayeng is a scheduled caste village of the Chakpa community in Imphal West district and its conservation efforts are mainly linked to the belief that the forest is a sacred grove. It is surrounded by three densely forested hillocks with fruit trees at centre and a stream flowing through it.

Notes:
Scientists at the Centre for Cellular & Molecular Biology (CCMB) have discovered a new enzyme ‘Murein Endopeptidase’ which helps in breaking cell walls of bacteria. This discovery offers a potential for a new drug delivery route to arrest the anti-bacterial resistance through existing antibiotic drugs. Hence, it opens up fresh ways to target microbes, leading to a new wave of antibiotic drugs. The man behind this discovery is Pavan Kumar Chodisetti, research student and his mentor Dr Manjula Reddy. Antibiotics are medicines used to prevent and treat bacterial infections. The findings have been published in the latest issue of Proceedings of National Academy of Sciences, USA

Notes:
A music and poetry festival titled ‘Jashn-e-Ittihaad’ was held at the Jamia Milia Islamia central university in New Delhi on April 6, 2019. The fest is one of a kind event where people will get to enjoy soulful Hindi and Urdu poetry, music and performances that will not only make them feel good but will also spread awareness about unity and integrity. The musical evening opened with the national anthem and a dance performance by young artistes Yuvraaj Katiyal and Mahira Katyal, followed by a performance by Irshad Kamil and his band — The Ink Band.
