Current Affairs Quiz - March, 2019

Notes:
Researchers from the University of Arkansas and Argonne National Lab in the US have identified more cost-effective and efficient ways of producing hydrogen fuel by splitting water. They showed that nano-particles composed of nickel and iron are better alternatives than more costly materials when used as catalysts in the production of hydrogen fuel through water electrolysis. The team demonstrated that using nanocatalysts composed of nickel and iron increases the efficiency of water electrolysis, the process of breaking water atoms apart to produce hydrogen and oxygen and combining them with electrons to create hydrogen gas. When nanoparticles composed of an iron and nickel shell around a nickel core are applied to the process, they interact with the hydrogen and oxygen atoms to weaken the bonds, increasing the efficiency of the reaction by allowing the generation of oxygen more easily.This marks a step toward making water electrolysis a more practical and affordable method for producing hydrogen fuel. Current methods of water electrolysis are too energy-intensive to be effective.

Notes:
Researchers at Purdue University in the US, including one of Indian origin, have developed a new process to remove nearly all traces of oil in produced water — a byproduct from the oil refinery and extraction process. The process uses activated charcoal foam and subjects it to solar light to produce heat and purify the water. The foam absorbs the oil contaminants from the water. Ashreet Mishra, a graduate research assistant at the Purdue University, said that this is a simple, clean and inexpensive treatment process. The process meets all environmental standards for clean water from industrial sources and had a total organic carbon of 7.5 milligrams per litre. Another advantage is that the oil absorbed by the foam can be recovered efficiently. The researchers were able to recover up to 95% of the oil that was absorbed. The process could be integrated with existing disposal systems to purify a large amount of water and reduce the current stress on water grids.

Notes:
Ministry of Corporate Affairs (MCA) has recently released the National Guidelines on Responsible Business Conduct (NGRBC). These guidelines urge businesses to actualize the principles in letter and spirit. For this purpose, the National Voluntary Guidelines on Social, Environmental and Economic Responsibilities of Business, 2011 (NVGS) have also been revised. According to the guidelines, businesses should conduct and govern themselves with integrity in a manner that is ethical, transparent and accountable. Businesses should provide goods and services in a manner that is sustainable and safe. It should also respect and promote the well-being of all employees, including those in their value chains.

Notes:
The World Poetry Day (WPD) is celebrated every year on 21st of March across the world to recognize the unique ability of poetry to capture the creative spirit of the human mind. . The day was adopted in 1999 during UNESCO’s 30th session held in Paris. The observance of the day is also meant to encourage a return to the oral tradition of poetry recitals, to promote the teaching of poetry, to restore a dialogue between poetry and the other arts such as theatre, dance, music and painting, and to support small publishers and create an attractive image of poetry in the media, so that the art of poetry will no longer be considered an outdated form of art, but one which enables society as a whole to regain and assert its identity.

Notes:
The World Meteorological Day (WMD) is observed every year on 23rd of March to mark the establishment of World Meteorological Organization (WMO) on this day in 1950. This year, the organisation is celebrating its 69th anniversary. The 2019 theme ‘The Sun, the Earth and the weather” recognizes the critical role that the Earth’s nearest star plays in what transpires on the planet. The energy that the Sun sends towards the Earth is taken up by all life forms to perform their biological functions. It also regulates global climate, which, in turn, influences local weather conditions. The same energy is also absorbed by the oceans which carry it around the planet, creating further conditions for diverse marine life to exist.

Notes:
Australian researchers, at the Australian Research Council (ARC) Centre of Excellence for Nanoscale BioPhotonics, have developed a new automated non-invasive technique for diagnosing eye surface cancer. The novel technique involves custom-building of an advanced imaging microscope linked with computing and Artificial Intelligence (AI) operations. It results in an automated system that is able to successfully identify between diseased and non-diseased eye tissue, in real-time, through a simple scanning process. The new technique scans natural light given off by specific eye cells — diseased cells — that have their own unique ‘light-wave signature’. This new technique offers the potential to reduce the need for biopsies, prevent therapy delays, and make treatment far more effective for patients. Eye surface cancer, also known as Ocular Surface Squamous Neoplasia (OSSN), is a common malignancy of the cornea and conjunctiva parts of the eye.

Notes:
Indian paddler Archana Kamath clinched a silver in the under-21 women’s singles section of the Seamaster ITTF Challenge Plus 2019 Oman Open table tennis tournament at Muscat. Archana started playing table tennis at the age of 9 years. She won her first U-12 and also a U -18 State title in 2011, and retained her Karnataka State No 1 Sub-Junior ranking throughout 2012 with some consistent performances. Since 2013 her career graph has seen a very steep rise. As a player, she describes herself as a fierce attacker.

Notes:
On 21st March, Italy’s PRISMA Earth observation satellite launched into orbit by the European Vega rocket from the Guiana Space Center in Kourou, French Guiana. PRISMA (or Precursore Iperspettrale della Missione Applicativa) is a small hyperspectral imaging satellite i.e. designed to provide information about environmental monitoring, resources management, pollution and crop health. The satellite includes a medium resolution camera that can view across all visual wavelengths, as well as a hyperspectral imager that can capture a wider range of wavelengths between 400 and 2500 nanometers. The satellite will operate in a sun-synchronous orbit, meaning that it circles the Earth in such a way that the sun is always in the same position as the satellite takes pictures of the planet below. PRISMA has been constructed by OHB Italia and will be operated by the Italian Space Agency “Agenzia Spaziale Italiana (ASI)”.

Notes:
Chennai Super Kings star Suresh Raina has scripted history as he became the first cricketer in the history of the Indian Premier League (IPL) to score 5,000 runs. He reached the milestone during the first match of the 2019 IPL season against Royal Challengers Bangalore at MA Chidambaram Stadium in Chennai. Raina has 5000 runs from 177 matches at a strike-rate of 138.15 including 35 fifties and one hundred.

Notes:
Peter Tabichi, a science teacher from rural Kenya who donates most of his salary to help poorer students, has been crowned the world’s best teacher and awarded a $1m prize in Dubai. He is the maths and physics teacher at Keriko secondary school in Pwani Village, in a remote part of Kenya’s Rift Valley, has won the Varkey Foundation Global Teacher Prize 2019. Tabichi gives away 80% of his income to help the poorest students who live in poverty and are either orphans or from single-parent families. He changed the lives of his students in many ways, including the introduction of science clubs and the promotion of peace between different ethnic groups and religions. He has also helped to address food insecurity among the wider community in the famine-prone Rift Valley. Drug abuse, teen pregnancies, drop-outs, and suicide are common, and the school has one computer, poor internet access, and a student-teacher ratio of 58:1. In spite of those circumstances, Tabichi’s science students have won various national science competitions, and qualified to participate at the Intel International Science and Engineering Fair 2019 in the US.
