/ Mahatma Gandhi

+ You must be the change you wish to see in the world.

+ The weak can never forgive. Forgiveness is the attribute of the strong.

+ Happiness is when what you think, what you say, and what you do are in harmony.

+ An eye for eye only ends up making the whole world blind.

+ Live as if you were to die tomorrow; learn as if you were to live forever.

+ First they ignore you, then they laugh at you, then they fight you, then you win.

+ You must not lose faith in humanity. Humanity is an ocean; if a few drops of the ocean are dirty, the ocean does not become dirty.

+ The best way to find yourself is to lose yourself in the service of others.

+ Strength does not come from physical capacity. It comes from an indomitable will.

+ A man is but the product of his thoughts; what he thinks, he becomes.

“Your time is limited, so don’t waste it living someone else’s life. Don’t be trapped by dogma, which is the result of living with the results of other people’s thinking. Don’t let the noise of other’s opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.”

KIKIKI HUNA

Recently it has been found in Tamil Nadu, India.

Features
Smallest insect in the world, dimension: 0.16 mm
A multicellular organism that is smaller than single-celled organisms.
Like all fairyflies, Kikiki huna lays its eggs in the eggs of other insects.
The entire life stage is passed in the single egg, from which it emerges as an adult.
It was first discovered in Trinidad around 20 years ago and later in Hawaii.
Other countries where it has been found: Australia and Argentina.

Recently, Australia based the Walk Free Foundation has published the Global Slavery Index 2016.

What is Modern Slavery?

It refers to situations where one person has taken away another person’s freedom — their freedom to control their body, their freedom to choose to refuse certain work or to stop working —so that they can be exploited.

Highlights of the report

It estimates that 45.8 million people are subject to some form of modern slavery in the world.

This year’s estimates are nearly 30% higher than in the previous report of 2014, with 35.8 million.

The countries with the highest estimated prevalence of modern slavery by the proportion of their population are North Korea,
Uzbekistan, Cambodia, India, and Qatar.

The countries with highest absolute numbers of people in modern slavery are India (18.35 million), China (3.39 million), Pakistan (2.13 million), Bangladesh (1.53 million), and Uzbekistan (1.23 million).

Internal waves, which move vertically through the ocean, can sometimes pass through “water staircases,” which are step like variations of density of water, in such as manner as to churn up the underlying warm, salty water, thereby increasing the temperature of the top, cooler layers, according to a paper published in Physical Review Fluids. This suggests a possible mechanism by which the upper layers of the Arctic Ocean warm up, causing the ice to melt.

Water staircases are step like variations of density of water due to step like changes in temperature and salinity. Though internal waves exist where the density gradually increases with depth, they cannot propagate where the density is uniform, for instance, within the steps of the staircase. While the passage of waves through a single step was studied earlier, the interaction between waves and multiple steps was not really understood well and is considered for the first time in this paper.

Ocean warming
The Arctic Ocean has inflows coming from the Pacific Ocean and Atlantic Ocean. In this, the top layers consist of cooler and less saline water and below that is a layer of water coming from the Atlantic Ocean which is more saline and warmer, too. The effect of salinity wins over that of temperature and so, though the water below is warmer, it is heavier than the cooler, less saline layer on top..

“Warm, but salty water — ultimately originating from the Atlantic Ocean resides near the bottom of the Arctic Ocean. If turbulence could somehow mix this water with that above, then, eventually, the surface could warm more rapidly, and this would increase the rate of sea-ice melt. One mechanism for mixing is the result of breaking internal waves,” says Bruce Sutherland, University of Alberta, Canada, the author of the paper, in an email interview.

The internal movement of water within seas from cold, dense regions to warmer, lighter ones constitutes the largest observable waves. These can stretch to wavelengths of over a hundred metres and travel from top to bottom. Like normal water waves, these propagate due to a variation of density of the water and not when there is constant density. In a staircase-like formation, though the density is constant within the step, there is a jump in density from one step to another. Hence, the wave’s energy can be transmitted from one interface to another.

Though not predominant, thermohaline staircases do occur in many places. “As well as the Arctic, they are persistent in the Caribbean Sea. This is due to surface heating and evaporation resulting in warm salty water overlying colder fresher water. They do not exist where there are strong currents, as in the Antarctic, which have enough energy to stir up any staircases that might form,” says Dr Sutherland.

Selective filtering
So the scenario is that when an internal wave strikes a density staircase, a part of its energy may be transmitted through the staircase. In other words, density staircases in the ocean can act to reflect short wavelength internal waves and transmit longer wavelength waves. This is analogous to the selective transparency of glass windows on modern buildings that have multilayered coatings designed to reflect red light (long wavelength light) and allow green-blue (shorter wavelength) light through

On reaching the ocean floor, the long-wavelength waves which have been transmitted cause turbulence and mix up the water. The warm waters then rise to the top and warm the top layers.

“Strong storms passing over the Arctic typically generate waves on the order of 10-100 km horizontal scale. As sea-ice retreats and storms passing over the increasingly non-ice-covered ocean generate more and more waves, it seems that still a substantial fraction of this energy can transmit to depth, and this may consequently cause mixing at depth that could bring those deep warm (but salty) waters closer to the surface. The filtering that my theory predicts suggests that the energy transmitted to depth might be moderately smaller than one would expect in the absence of density staircases. But, for the most energetic waves — those transmitted by storms — the decrease is not substantial,” says Dr Sutherland.

OCEAN CURRENTS are streams of water flowing constantly on the ocean surface in definite directions. The ocean currents may be warm or cold.

Generally, the warm ocean currents originate near the equator and move towards the poles. The Gulf Stream is a warm current.

The cold currents carry water from polar or higher latitudes to tropical or lower latitudes. The Labrador Ocean current is cold current.

The ocean current influence the temperature conditions of the area. Warm currents bring about warm temperature over land surface.

The areas where the warm and cold currents meet provide the best fishing grounds of the world. Seas around Japan and the eastern coast of North America are such examples. The areas where a warm and cold current meet also experience foggy
weather making it difficult for navigation.
