So today’s post is about you, about us. I mean about our personality , about our identity, our views , our behavior, etc. Personality development encompasses the dynamic construction and deconstruction of integrative characteristics that distinguish an individual in terms of interpersonal behavioral traits.

Indeed , personality development is ever -changing and subject to contextual factors and life altering experiences. Personality development is also dimensional in description and subjective in nature. The dominant viewpoint in personality psychology indicates that personality emerges early and continues to develop across one’s lifespan.

We all possess certain personality traits that set us apart from the rest. A mix of good and bad, these traits define how we respond to situations and people. Now I tell 13 personality development ‘tips’. I hope you will enjoy reading it and become the most terrific version of you.

13 ways of personality development :

• Know you are incomparable – Know that you and the other person are unique and are just incomparable
• Be kind to yourself – Self compassion brings positive traits in life.
• Give space to imperfections – Find your peace amidst the world’s flaws even as you strive to make a change.
• Be spontaneous – Spontaneity makes one to be fun around and be per cent aware in the present moment.
• Be light in mind and heart – Be happy and don’t overthink and overanalyze yourself.
• Stay enthusiastic – Enthusiasm is infectious and appealing so one must never give up enthusiasm.
• Be a better communicator – A skillful communicator can win over people and adverse situations through his words.
• Be warm and approachable – We all like people whom we can easily mingle and talk to. Be friendly and be ready to share and help.
• Do things with style – Doing things with style adds zing to your personality. At the same time, stay relaxed.
• Learn to let go – After you’re done with your task, let go of your attachment with the result.
• Be a lion in the face of danger – Don’t give into pressure and face every challenge confidently.
• Stay calm with the power of breath – Being calm strengthens one’s personality and your stress will diminish.
• Remember you’re a proton! – A proton never lose its positivity, nor can you. Your inner core continues to radiate positivity.

That’s all for today hope you will like it!! Thank you…

Ozone layer depletion

Ozone is a form of oxygen (O3). In the stratosphere (Ozonosphere),ozone blocks out the sun’s ultraviolet rays and is a life saver.

Ozone as a natural sun block

The electromagnetic radiation emitted from the sun includes ultraviolet radiation, which is potentially harmful to most living things since it can damage DNA. The ozone layer screen out the sun’s harmful ultraviolet radiation. Even 1% reduction in the amount of ozone in the upper stratosphere causes a measurable increase in the ultraviolet radiation that reaches the earth surface. If there was a no ozone at all ,the amount of ultraviolet radiation reaches us would be catastrophically high. All living things would suffer radiation burns,unless they were underground, or in the sea.

In the stratosphere, small amount of ozone are constantly being made by the action of sunlight on oxygen. At the same time, ozone is being broken down by natural processes. The total amount of ozone usually stays constant because its formation and destruction occur at about the same rate. But unfortunately human activity has recently changed that natural balance. Some manufactured substances such as chloroflurocarbons and hydrochloroflurocarbons can destroy stratosphere ozone much faster than it is formed.

Ozone hole

Ozone loss was first detected in the stratosphere over the Antarctic. The part of the atmosphere where Ozone is most depleted is referred as ” Ozone hole” but it is not a real hole just a vast region of the upper atmosphere where there is less Ozone than elsewhere.

Ozone-poor air can spread out from the polar regions and move above others areas. In addition, direct Ozone less elsewhere is slowly increasing.

Ozone-poor air can spread out from the polar regions and move above other areas. In addition, direct Ozone depleted area is also slowly increasing.

Reason for Antarctic Ozone hole

Scientific observation prove that the ozone hole formed over Antarctic is due to compounds of chlorine and bromine formed in the atmosphere. Nearly all of the chlorine and half of the bromine in the stratosphere comes from the human activities. The chlorofluorocarbons released due to human activities get transported up into the upper stratosphere.

The most common ozone depleting substances (ODS) are chlorofluorocarbons (CFC) or freon gases,certain bromine compounds, nitrogen oxides and methyl bromide. These compounds are liberally released from air-conditioners,freezers,foam insulation, aerosol products, industrial solvents, fire extinguishers and pesticides.

Effects of ozone depletions

If the ozone is depleted more ultraviolet radiation (especially ultraviolet B (UVB) will reach the earth’s surface.

Effect on plants – will affect crop yield and forest productivity.

Effect on animals – will cause damage to fish larvae and other Small animals.

Effect on human health – results in non – melanoma skin cancer and melanoma ,acute erythemia(sun burn), ocular abnormalities, cataract,poor immune responses.

Preventing ozone depletion

1. CFC’s ( Chloro Fluoro Carbons) should be replaced by HCFC’s (Hydro Chloro Fluro Carbons). If over used could damage ozone, HFC’s ( Hydro Flouro Carbons), Hydrocarbons such as butane and propane ( but flammable and poisonous), Ammonia ( must be handled carefully), water and steam.

2. Production, use and emission of ozone-depleting chemicals should be controlled.

3. Recycling of these chemicals should be increased.

4. Servicing of refrigerators and air-conditioners should be regulated.

5. Refrigerants should be recaptured and used .

6. Adopt protection measures from sun’s radiation.

What is the Atmosphere?

The atmosphere is a mixture of gases that surrounds the planet. On Earth, the atmosphere helps make life possible. Besides providing us with something to breathe, it shields us from most of the harmful ultraviolet (UV) radiation coming from the Sun, warms the surface of our planet by about 33° C (59° F) via the greenhouse effect, and largely prevents extreme differences between daytime and nighttime temperatures. The other planets in our solar system also have an atmosphere, but none of them have the same ratio of gases and layered structure as Earth’s atmosphere. 

Gases in Earth’s Atmosphere

Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen  (N₂) and about 21% oxygen  (O₂). Argon, carbon dioxide (CO₂), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere’s mixture of gases. The atmosphere also includes water vapor. The amount of water vapor present varies a lot, but on average is around 1%. There are also many small particles – solids and liquids – “floating” in the atmosphere. These particles, which scientists call “aerosols”, include dust, spores and pollen, salt from sea spray, volcanic ash, smoke, and more.

Layers of Earth’s Atmosphere

The atmosphere grows thinner (less dense and lower in pressure) as one moves upward from Earth’s surface. It gradually gives way to the vacuum of outer space. There is no precise “top” of the atmosphere. Air becomes so thin at altitudes between 100 and 120 km (62-75 miles) up that for many purposes that range of heights can be considered the boundary between the atmosphere and space. However, there are very thin but measurable traces of atmospheric gases hundreds of kilometers/miles above Earth’s surface.

There are several different regions or layers in Earth’s atmosphere. Each has characteristic temperatures, pressures, and phenomena. We live in the troposphere, the lowest layer, where most clouds  are found and almost all weather occurs. Some jet aircraft fly in the next higher layer, the stratosphere, which contains the jet streams and the ozone layer. Temperatures reacj their lowest in the mesosphere, because the there are almost no air molecules there to absorb heat energy. The sky also changes from blue to black in the mesosphere, because there are so few molecules for light to refract off of there. And fartherst from the surface we have the thermosphere, which is the widest layer of the atmosphere and absorbs much of the harmful radiation that reaches Earth from th Sun. The exosphere represents the transition from Earth’s atmosphere to space. 

Troposphere

The troposphere  is the lowest layer of our atmosphere. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. We humans live in the troposphere, and nearly all weather occurs in this lowest layer. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. Air pressure drops, and temperatures get colder, as you climb higher in the troposphere.

Stratosphere

The next layer up is called the stratosphere. The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. The infamous ozone layer is found within the stratosphere. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat. Unlike the troposphere, the stratosphere actually gets warmer the higher you go! That trend of rising temperatures with altitude means that air in the stratosphere lacks the turbulence and updrafts of the troposphere beneath. Commercial passenger jets fly in the lower stratosphere, partly because this less-turbulent layer provides a smoother ride. The jet stream flows near the border between the troposphere and the stratosphere.

Mesosphere

Above the stratosphere is the mesosphere. It extends upward to a height of about 85 km (53 miles) above our planet. Most meteors burn up in the mesosphere. Unlike the stratosphere, temperatures once again grow colder as you rise up through the mesosphere. The coldest temperatures in Earth’s atmosphere, about -90° C (-130° F), are found near the top of this layer. The air in the mesosphere is far too thin to breathe; air pressure at the bottom of the layer is well below 1% of the pressure at sea level, and continues dropping as you go higher.

Thermosphere

The layer of very rare air above the mesosphere is called the thermosphere. High-energy X-rays and UV radiation from the Sun are absorbed in the thermosphere, raising its temperature to hundreds or at times thousands of degrees. However, the air in this layer is so thin that it would feel freezing cold to us! In many ways, the thermosphere is more like outer space than a part of the atmosphere. Many satellites actually orbit Earth within the thermosphere! Variations in the amount of energy coming from the Sun exert a powerful influence on both the height of the top of this layer and the temperature within it. Because of this, the top of the thermosphere can be found anywhere between 500 and 1,000 km (311 to 621 miles) above the ground. Temperatures in the upper thermosphere can range from about 500° C (932° F) to 2,000° C (3,632° F) or higher. The aurora, the Northern Lights and Southern Lights, occur in the thermosphere.

Exosphere

Although some experts consider the thermosphere to be the uppermost layer of our atmosphere, others consider the exosphere  to be the actual “final frontier” of Earth’s gaseous envelope. As you might imagine, the “air” in the exosphere is very, very, very thin, making this layer even more space-like than the thermosphere. In fact, the air in the exosphere is constantly – though very gradually – “leaking” out of Earth’s atmosphere into outer space. There is no clear-cut upper boundary where the exosphere finally fades away into space. Different definitions place the top of the exosphere somewhere between 100,000 km (62,000 miles) and 190,000 km (120,000 miles) above the surface of Earth. The latter value is about halfway to the Moon!

Ionosphere

The ionosphere  is not a distinct layer like the others mentioned above. Instead, the ionosphere is a series of regions in parts of the mesosphere and thermosphere where high-energy radiation from the Sun has knocked electrons loose from their parent atoms and molecules. The electrically charged atoms and molecules that are formed in this way are called ions, giving the ionosphere its name and endowing this region with some special properties.

Planetary Atmospheres

Earth is not the only world with an atmosphere. All of the planets – and even a few moons – in our solar system have atmospheres. Some have clouds, wind, rain and powerful storms. Recently scientists have also begun to get glimpses of atmospheres of planets in other solar systems.

Each of the planets in our solar system has an uniquely structured atmosphere. The atmosphere of Mercury is extremely thin and is not very different from the vacuum of space. All four giant planets in our solar system – Jupiter, Saturn, Uranus and Neptune – have very thick, deep atmospheres. The smaller, rocky planets – Earth, Venus and Mars – have much thinner atmospheres hovering above their solid surfaces. The atmospheres on moons in our solar sytem are typically quite thin. Saturn’s moon Titan is an exception – air pressure at the surface of Titan is higher than on Earth! Of the five officially recognized dwarf planets, Pluto has a thin, seasonal atmosphere containing nitrogen, methane  and carbon monoxide, and Ceres may have an extremely thin atmosphere of water vapor. But only Earth’s atmosphere has the layered structure that allows enough light energy to enter and be trapped for warmth, but also shields us from too much harmful radiation. This important balance is necessary to maintain life on Earth. 

Indian had a roller-coaster path during the Tokyo Olympics. It started with a bang, struggled in the middle, and then ended with a stunning win that makes the grand event historic.
The first medal was won in track-and-field which happened to be the first gold in 13 years, the first medal in hockey in 41 years, the first woman with two Olympic medals, first silver in weightlifting, first boxing medal in 9 years, the most number of debutants ending up on the podium, and the most numbers of medal ever for India in happened in one single game.
Whereas some missed to reach out to the podium by one step. Their anguish is a story in itself the women’s hockey team and golfer Aditi ended up covering the distance of the podium but was unable to reach there. India’s overall performance was bigger than the remarkable seven medals in the game. All the Olympians reflected confidence which can be best exemplified through Neeraj Chopra when he won the Olympic Stadium with his self-assured pace during the final throw.
India’s Olympic crusade was a story of human vitality as of sporting virtue. India’s story of progress in sports, the country isn’t at the highest yet but certainly inching closer one at a time.

Another article is management related. One of the basic and core part is organizational behavior in an organization. Organizational behavior (known as OB) is the” study of human behavior ” in organizational settings, the interface between human behavior and the organization itself.

• OB research can be categorized in at least three ways. The following three ways are mentioned as under :-
• Individual in organization (MICRO LEVEL)
• Work groups (MESO LEVEL)
• How organizations behave (MACRO LEVEL)

Organizational Behavior is the academic study of how people act within groups. It’s principles are applied primarily in attempts to make businesses operate more effectively. The study of organizational behavior includes areas of research dedicated to improving job performance, increasing job satisfaction, promoting innovation and encouraging leadership.

The new frontiers of organization behaviour are the cultural components of organization, such as how race, class and gender roles affect group building and productivity. Organizational Behavior is the study of how people behave within groups. Early studies determined the importance of group dynamics in business productivity.

The study of organizational behavior gives insight on how employees behave and perform in the workplace. It helps us develop an understanding of the aspects that can motivate employees, increase their performance and help organization’s establish a strong and trusting relationship with their employees.

The topic for today’s article is scrap policy in India. Now the question is what is meant by scrap? The answer to this is – to remove an unwanted covering or a top layer from something. Scrap consists of recyclable materials left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials.

Unlike waste, scrap has monetary value, especially recovered metals and non-metallic ,especially are also recovered for recycling. And the much -awaited draft policy on vehicle scrapping is finally out.

The policy outlines the criteria for defining end -of-life vehicles and scrapping them. It also makes provision for scrapping facilities for safe disposal of waste and material recovery. This policy has only “advised” the state governments and the automobile industry to provide voluntary incentives to the owners of the vehicles.

This proposed policy seeks to phase out unit vehicles to reduce vehicular pollution, meet the climate commitments, improve road safety and fuel efficiency, formalise informal vehicle scrapping industry and recover low cost material for automotive, steel and electronics industry. The vehicle scrapping scheme is likely to usher in significant change and is expected to generate demands for new vehicles.

The policy says, commercial vehicles of more than 15 years and passenger vehicles of more than 20 years will have to be mandatorily scrapped if they don’t pass the fitness and emission tests. Vehicle owners who would voluntarily scrap their vehicles will get a rebate on road tax in the range of 15% to 25% and complete waiver of registration fees on the next vehicle purchase.

The government has envisaged investments worth Rs 10000 core for establishing vehicle fitness centers. Most likely scrapyards are to be established in the four zones and they will also supply scrap steel to automobile manufactures and other industries. The milestones set in the draft policy require the rules for fitness tests and scrapping to be in place by October 1, 2021. All government and PSU -owned vehicles older than 15 years will be scrapped by October 1, 2022. The same will be done for other vehicles by 2023 and 2024.

Starfish (or sea stars) are beautiful marine animals  found in a variety of colors, shapes, and sizes. All starfish resemble stars, and though the most common have only five arms, some of these animals can grow up to 40 arms. The amazing sea creatures—part of a group of animals known as echinoderms—travel using their tube feet. They can regenerate lost limbs and swallow large prey using their unusual stomachs.

Sea Stars Are Not Fish

Although sea stars live underwater and are commonly called “starfish,” they are not true fish. They do not have gills, scales, or fins like fish do.

Sea stars also move quite differently from fish. While fish propel themselves with their tails, sea stars have tiny tube feet to help them move along.

Because they are not classified as fish, scientists prefer to call starfish “sea stars.”

Sea Stars Are Echinoderms

Sea stars belong to the phylum Echinodermata. That means they are related to sand dollars, sea urchins, sea cucumbers, and sea lilies. Overall, this phylum contains approximately 7,000 species.

Many echinoderms exhibit radial symmetry, meaning their body parts are arranged around a central axis. Many sea stars have five-point radial symmetry because their body has five sections. This means that they do not have an obvious left and right half, only a top side and a bottom side. Echinoderms also usually have spines, which are less pronounced in sea stars than they are in other organisms such as sea urchins.

There Are Thousands of Sea Star Species

There are about 2,000 species of sea stars. Some live in the intertidal zone, while others live in the deep water of the ocean. While many species live in tropical areas, sea stars can also be found in cold areas—even the polar regions.

Not All Sea Stars Have Five Arms

While many people are most familiar with the five-armed species of sea stars, not all sea stars have just five arms. Some species have many more, such as the sun star, which can have up to 40 arms. 

Sea Stars Can Regenerate Arms

Amazingly, sea stars can regenerate lost arms, which is useful if a sea star is injured by a predator. It can lose an arm, escape, and grow a new arm later.

Sea stars house most of their vital organs in their arms. This means that some species can even regenerate an entirely new sea star from just one arm and a portion of the star’s central disc. This won’t happen too quickly, though; it takes about a year for an arm to grow back.

Sea Stars Are Protected by Armor

Depending on the species, a sea star’s skin may feel leathery or slightly prickly. Sea stars have a tough covering on their upper side, which is made up of plates of calcium carbonate with tiny spines on their surface.

A sea star’s spines are used for protection from predators, which include birds, fish, and sea otters. One very spiny sea star is the aptly named crown-of-thorns starfish.

Sea Stars Do Not Have Blood

Instead of blood, sea stars have a circulatory system made up primarily of seawater.

Seawater is pumped into the animal’s water vascular system through its sieve plate. This is a sort of trap door called a madreporite, often visible as a light-colored spot on the top of the starfish.

From the madreporite, seawater moves into the sea star’s tube feet, causing the arm to extend. Muscles within the tube feet are used to retract the limb.

Sea Stars Move Using Their Tube Feet

Sea stars move using hundreds of tube feet located on their underside. The tube feet are filled with seawater, which the sea star brings in through the madreporite on its top side.

Sea stars can move quicker than you might expect. If you get a chance, visit a tide pool  or aquarium and take a moment to watch a sea star moving around. It is one of the most amazing sights in the ocean.

Tube feet also help the sea star hold its prey, including clams and mussels.

Sea Stars Eat With Their Stomachs Inside-Out

Sea stars prey on bivalves like mussels and clams as well as small fish, snails, and barnacles. If you’ve ever tried to pry the shell of a clam or mussel open, you know how difficult it is. However, sea stars have a unique way of eating these creatures.

A sea star’s mouth is on its underside. When it catches its food, the sea star will wrap its arms around the animal’s shell and pull it open just slightly. Then it does something amazing: the sea star pushes its stomach through its mouth and into the bivalve’s shell. It then digests the animal and slides its stomach back into its own body.

This unique feeding mechanism allows the sea star to eat larger prey than it would otherwise be able to fit into its tiny mouth.

Sea Stars Have Eyes

Many people are surprised to learn that starfish have eyes. It’s true. The eyes are there—just not in the place you would expect.

Sea stars have an eye spot at the end of each arm. This means that a five-armed sea star has five eyes, while the 40-armed sun star has 40 eyes.

Each sea star eye is very simple and looks like a red spot. It doesn’t see much detail but it can sense light and dark, which is just enough for the environments the animals live in.

All True Starfish Are in the Class Asteroidea

Starfish belong to the animal class Asteroidea. These echinoderms all have several arms arranged around a central disk.

Asteroidea is the classification for “true stars.” These animals are in a separate class from brittle stars and basket stars, which have a more defined separation between their arms and their central disk.

Sea Stars Have Two Ways to Reproduce

Male and female sea stars are hard to tell apart because they look identical. While many animal species reproduce using only one method, sea stars are a little different.

Sea stars can reproduce sexually. They do this by releasing sperm and eggs (called gametes) into the water. The sperm fertilizes the gametes and produces swimming larvae, which eventually settle on the ocean floor, growing into adult sea stars.

Sea stars can also reproduce asexually through regeneration, which is what happens when the animals lose an arm.
