International Maritime Orgnaisation (IMO) has notified  new rules, which cut current sulphur content in shipping oil by 85%

Going deeper, we can expect the post 2020 fuels to fall into five main categories:

• Ultra-low sulphur fuel oil (ULSFO), max 0.10%
• Very-low sulphur fuel oil (VLSFO), max 0.50%
• Heavy fuel oil, max 3.50%
• LNG (liquid natural gas)

VLSFO is hence used for Maritime purposes. Though it is cleaner than heavy oils, it is problematic on one aspect that it is highly unstable and poses a great risk for mixing VLSFO with other fuels.

Ships that do not use VLSO have to use scrubbers.”Exhaust Gas Cleaning Systems” are otherwise called as scrubbers. The purpose of these scrubbers is to convert the SOx emissions into sulphuric acid and hence they reduce emissions. Since the sulphur content is itself low in VLSFO, the SOx emitted also is low and hence there is no need to install any such systems in ships that use VLSFO.

High and sustained GDP growth is necessary to mobilize resources to spend on welfare schemes for the poor and marginalized and to uplift these sections of the society.It is only by equipping the poor with skills and good health they can be made as equal participants in the process of achieving growth.

Frost weathering is a collective term for several mechanical weathering processes induced by stresses created by the freezing of water into ice.
Alternate wetting and drying of soft or poorly cemented rocks such as shales causes fairly rapid breakdown of the rocks, and most disintegration may occur during the drying cycle and is an example of physical weathering.

Chemical weathering is the process by which rocks are broken down by chemical reactions. A type of chemical weathering is oxidation. Oxidation is the reaction of a substance with oxygen. You are probably familiar with oxidation because it is the process that causes rust. So, just like your car turns to rust through oxidation, rocks can get rusty if they contain iron.

When iron reacts with oxygen, it forms iron oxide, which is not very strong. So, when a rock gets oxidized, it is weakened and crumbles easily, allowing the rock to break down. Iron oxide is kind of brownish-red in colour, and this explains why some rocks look red.

Trade and Commerce bloomed in the 1^st CE. Accounts of Roman Historians testify to the prevalence of trade in luxury items between India and Rome. Trade routes such as Uttarapadha and Dakshinapadha signify the trade and commerce between various parts of the country.

Various copper plate inscriptions point out that during this period esp. in the time of Guptas, brahmanas were given land grants by kings as well as by private Individuals.Bengal inscriptions mention that land grants were requested by brahmanas and were generously given by private individuals.

In the later part of the millennium the use of coinage decreases significantly. The discovery of cowrey shells commonly in this phase points out to the use of Cowrey shells as a medium of transaction and a subsequent decrease in the use of high value gold and silver coins. This points to the decreasing trade and commerce activities in this period.

The Keibul Lamjao National Park is a national park in the Bishnupur district of the state of Manipur in India. It is 40 km² in area, the only floating park in the world, located in North East India, and an integral part of Loktak Lake.
