1) Consider the following statements about the Dredging Corporation of India Ltd.

I) It is a Maharatna Indian public sector unit engaged in the business of dredging.
II) Presently the Government of India holds 100% shares in Dredging Corporation of India Limited.

Choose the correct options from below

a) Only I
b) Only II
c) Both I & II
d) Neither I nor II


Answer: d
• Cabinet approves strategic disinvestment of 100% Govt. of India’s equity in the Dredging Corporation of India Ltd. (DCIL).
• The Cabinet Committee on Economic Affairs chaired by the Prime Minister has given ‘in principle’ approval for strategic disinvestment of 100% Government of India’s shares in DCIL to consortium of four ports namely: Vishakhapatnam Port Trust, Paradeep Port Trust, Jawahar Lal Nehru Port Trust and Kandla Port Trust.
• Presently the Government of India holds 73.44% shares in Dredging Corporation of India Limited.
• The approval will further facilitate the linkage of dredging activities with the ports, keeping in view the role of the DCIL in expansion of dredging activity in the country as well as potential scope for diversification of ports into third party dredging.
• This would further provide opportunities for larger investment in DCIL as integration with ports shall help ineffective vertical linkage in the value chain.
• Dredging Corporation of India Limited, or DCI, is a Miniratna Indian public sector unit engaged in the business of dredging.
• DCI does dredging for Indian seaports exclusively.
• It occasionally dredges at foreign seaports in countries such as Sri Lanka, Taiwan and Dubai.
• It is mainly involved in maintenance dredging.
• Almost all the maintenance dredging in Indian seaports is carried out by DCI due to government regulations.
• DCI is also involved in capital dredging, beach nourishment, and land reclamation.


2) Consider the following statements about “Bionic Mushrooms”

I) They have been made by supercharging mushrooms with clusters of cyanobacteria that create electricity and swirls of graphene nanoribbons that can collect the current.
II) Since cyanobacteria can survive long on artificial bio-compatible surfaces, it reveals new avenues for ‘green’ power

Select the correct option from below

a) Only I
b) Only II
c) Both I & II
d) Neither I nor II


Answer: a
• Scientists, including those of Indian origin, have created a bionic device that generates green power by 3D-printing clusters of cyanobacteria on an ordinary white button mushroom.
• The researchers took an ordinary white button mushroom from a grocery store and made it bionic, supercharging it with clusters of cyanobacteria that create electricity and swirls of graphene nanoribbons that can collect the current.
• Cyanobacteria’s ability to produce electricity is well known.
• However, researchers have been limited in using these microbes in bioengineered systems because cyanobacteria do not survive long on artificial bio-compatible surfaces.


3) Simbex 2018, is a bilateral naval exercise between India and which of the following countries?

a) Sri Lanka
b) Singapore
c) South Korea
d) Seychelles


Answer: b
• Bilateral Exercise Between Indian & Republic of Singapore Navies – SIMBEX 18 – marks Silver Jubilee this Year.
• The 25th edition of SIMBEX, an acronym for “Singapore-India Maritime Bilateral Exercise” is scheduled from 10th to 21st November 2018 off Andaman Sea and Bay of Bengal.
• Bilateral cooperation between Singapore and India was first formalised when RSN ships began training with the Indian Navy in 1994.
• What began as a modest endeavour to exchange best practices in the field of Anti-Submarine Warfare (ASW).
• Significance:
o Complementing India’s ‘Act-East’ policy, there have been a number of agreements and high level visits in the recent past between the two countries.
o Both countries have a full calendar of more than 20 bilateral mechanisms, dialogues and exercises, many of which take place annually.
o In November 2015, the robust relationship between the two countries was elevated to ‘Strategic Partnership’.
• SIMBEX 2018 will be the largest edition since 1994 in terms of scale and complexity.


4) Ralph and Lucy are initiatives of which of the following organisations to explore Jupiter’s Trojan asteroids?

a) NASA
b) European Space Agency
c) Roscosmos
d) UK Space Agency


Answer: a
• NASA’s Ralph and Lucy are all set to explore Jupiter’s Trojan asteroids, which are remnants from the earliest days of our solar system.
• Ralph is a space instrument that has travelled as far as Pluto, while Lucy is a mission payload, or the spacecraft which would be carrying various scientific instruments including Ralph to study the properties of the asteroids.
• The mission will be launched in 2021 and would be the very first space mission to study the Trojans.
• The Trojan asteroids are orbit Sun in two loose groups — one group is always ahead of Jupiter (called the Greek camp) in its path while the other is always behind (called the Trojan camp). The two clusters are stabilized at these two Lagrange points in a gravitational balancing act between the Sun and Jupiter.
• As per the NASA all of the Trojans are thought to be abundant in dark carbon compounds. Below an insulating blanket of dust, they are probably rich in water and other volatile substances.
• The Trojan asteroids in Jupiter’s orbit could be made from the same material as the outer planets which were formed during the birth of the solar system more than 4 billion years ago.


5) Consider the following statements about the International Space Station

I) The ISS programme is a joint project among five participating space agencies: NASA, Roscosmos, ISRO, ESA, and CSA
II) It maintains an orbit with an altitude of between 1000-1500 km by means of reboost manoeuvres

Identify the correct option from below

a) Only I
b) Only II
c) Both I & II
d) Neither I nor II


Answer: d
• The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit. The ISS is now the largest artificial body in orbit.
• The ISS consists of pressurised modules, external trusses, solar arrays and other components. ISS components have been launched by Russian Proton and Soyuz rockets as well as American Space Shuttles.
• The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology and other fields.
• The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars.
• The ISS maintains an orbit with an altitude of between 330 and 435 km by means of reboost manoeuvres using the engines of the Zvezda module or visiting spacecraft. It completes 15.54 orbits per day.
• ISS is the ninth space station to be inhabited by crews, following the Soviet and later Russian Salyut, Almaz, and Mir stations as well as Skylab from the US.
• The ISS programme is a joint project among five participating space agencies: NASA, Roscosmos, JAXA, ESA, and CSA.
• The ownership and use of the space station is established by intergovernmental treaties and agreements. The station is divided into two sections, the Russian Orbital Segment (ROS) and the United States Orbital Segment (USOS), which is shared by many nations.
