PROMISES WE MAKE TO OURSELVES

 Resolutions 

     Are you ready to dive into the exciting world of New Year’s resolutions? As we bid farewell to the old year and welcome the new, many people around the world make promises to themselves called ‘resolutions.’ These promises help us become better versions of ourselves! 

   Did you know that sometimes, our New Year's resolutions might not go exactly as planned? And that's totally okay! Even if things didn't work out the way we wanted, it doesn't mean we should give up. It's like learning to ride a bike – at first, it might be tricky, but with practice and determination, we can get better! So, if your resolutions didn't quite work out, don't worry. You can try again or even change your goals to something that feels more achievable. Remember, the most important thing is to keep going and never stop believing in yourself. Every step you take counts, and you're awesome just for trying!

  Thousands of years ago, the ancient Babylonians (who lived in a place called Mesopotamia) were the first known people to make promises to their Gods at the start of the year. They celebrated their new year in March, not January like we do now! During a massive festival called Akitu, they made pledges to the Gods to return borrowed stuff and pay debts. Later on, the ancient Romans continued this tradition with a month-long celebration called "Janus", named after their God of beginnings. Janus had two faces – one looking forward to the future and the other looking back to the past. People made promises to Janus for good behaviour and changes they wanted to make in the upcoming year.

   New Year's resolutions are about promising ourselves to do better and be better. Whether it,s learning new things, being kinder or trying to eat more veggies, these resolutions are like little goals that help us grow and become even more awesome versions of ourselves!

ANCIENT TECHNICAL WONDER

Iron Pillar

     A 23 feet and 6 ton Pillar located at the Qutb Complex at Mehrauli in Delhi is an unsolved mystery. This pillar is made of iron and has attracted the attention of archeologists and material scientists across the world. 

     Standing at the centre of the Quwwatul Mosque the Iron Pillar dates back to 4th century AD. The pillar is made of 98% wrought Iron and has stood 1,600 years without rusting or decomposing. Its high resistance to corrosion is a proof of the high level of skill achieved by the ancient Indian iron smiths in the extraction and processing of Iron.

     The pillar carries a large number of inscriptions and graffiti of different dates. The oldest inscription on the pillar is that of a king named Chandra, generally identified as the Gupta emperor Chandragupta II. The script and the poetic style of the inscription point to a date in the late fourth or early fifth century i.e. the Gupta period. 

     The inscription describes the king as a devotee of the God Vishnu, and records the erection of a dhvaja (flag) of Vishnu, on a hill called Vishnupada (hill of the footprint of Vishnu). Other Gupta inscriptions also describe Chandragupta II as a Bhagavata.

     The greatest mystery is about its composition and non-corrosive nature. The pillar was manufactured by the forge welding of pieces of wrought iron. In a report published explains that the pillar's resistance to corrosion is due to a passive protective film at the iron-rust interface. 

Reason for formation of protective passive film:

* The presence of second-phase particles (slag and unreduced iron oxides) in the microstructure of the iron. 

* High amounts of phosphorus in it.

* Alternate wetting and drying existing under atmospheric conditions. 

The height of the pillar, from the top of its capital to the bottom of its base, is 23.8 feet. Out of this 3.8 feet part is below the ground. The diameter is 48cm at the foot, tapering to 29cm at the top, just below the base of the wonderfully crafted capital. The base rests on a grid of iron bars soldered with lead into the upper layer of the dressed stone pavement. It is estimated to weigh more than six tonnes.

The original location of the iron pillar is debatable. According to the inscription of king Chandra, the pillar was erected at Vishnupadagiri.

* J. F. Fleet (1898) describes the location as Mathura, because of its proximity to Delhi and the city's reputation as a Vaishnavite pilgrimage centre. But during Gupta age, Mathura was a Buddhist centre. 

* Based on the study of ancient and historical writings, the Gupta-era iconography, analysis of metallurgy and other evidence, Meera Dass and R. Balasubramaniam (2004) stated that the iron pillar was originally erected at Udaygiri. 

* It is not certain when the pillar was moved to Delhi from its original location. Its still a mystery that how the movement of pillar was done in those ancient days.

THE BEAUTIFUL MEDICINAL FLOWER

 Butterfly Pea 

     The butterfly pea (Clitoria ternatea), a native of South America that has long been naturalized to Malaysia, Indonesia and India, is an eye-catching plant with ornamental, medicinal, and culinary uses. The plant is distinguished by its flower, whose unusual shape has earned it the alternate name of conch flower (or shankh-pushpam in several South Indian languages). Another distinctive feature of this flower is its brilliant cobalt blue colour that gives rise to its use as a dye and food colorant. Interestingly, the colour changes based on the pH level of the substance added to it - a property that is utilized in making butterfly pea flower tea, a herbal beverage initially an attractive blue in colour but turning to purple when lemon juice is added to it. The plant is known as Aparajita in Hindi and other North Indian languages. Other names include Gokarna, Girikarnika, Kokila and Yonipushpa. 

     Ayurveda uses the whole plant and its parts including leaves, flowers and roots in remedies for a host of diseases. The plant also finds its application in the Chinese and Unani system of medicine.

     The butterfly pea plant is a climbing herb that is commonly found in hedgerows all over the country. The leaves are bright green, elliptic and obtuse. Flowers are conch-shaped, growing singly and are about 4cm long and 3cm broad. They are a vivid blue in colour, with yellow markings. There are also two other varieties yielding lilac and white flowers. Fruits are flat pods, up to 7cm long, tapering at both ends and containing 6 to 7 seeds.

     In Ayurveda, the butterfly pea has been grouped under the category of medhya, which includes herbs that help improve memory and learning. The plant root, ground to a paste mixed with ghee or butter, is prescribed for children to increase comprehension and retention. The root extract is also used in traditional remedies for insomnia, intoxication, schizophrenia, dizziness, balance problems and skin diseases. The seeds of the plant are used as a mild purgative and in the treatment of intestinal worms. A traditional remedy for constipation is a small quantity (one-eighth of a teaspoon) of roasted powdered seeds taken with warm water. The juice of the leaves, mixed with salt, is applied as a fomentation to cure earache. A few drops of root juice extract are put into the nostrils as a remedy for migraine. A decoction of the whole plant is gargled to treat sore throats and mouth ulcers. In Bali, the flowers are used in traditional remedies for eye infections such as conjunctivitis. 

     The butterfly pea plant also finds application in South East Asian cuisines. The flowers and leaves are used to make butterfly pea flower tea, mentioned earlier, which is a very popular beverage in Thailand and Vietnam. The tea is often added to cocktails to showcase the instantaneous colour change from blue to pink or purple. In Malaysian cuisine, the flowers are used in a breakfast dish called Nasi kerabu, consisting of blue-coloured rice (rice cooked with butterfly pea petals) eaten with chicken or fish, fries, pickle and salad. The same dish is also made in Thailand, where it is known as Khao yam. In Myanmar and Thailand, the flowers are dipped in butter and fried as snacks.

A DEVICE THAT GENERATES OZONE

Ozoniser

    It is a type of air or water purifier that uses ozone to kill bacteria and remove contaminants from food and water. 

     Ozone is a naturally occurring gas. A molecule of ozone has three oxygen atoms. Ozone is found in low concentrations throughout Earth's atmosphere. While the ozone layer shields Earth from the harmful ultraviolet rays of the Sun, it is a pollutant at ground level. 

  However, when used in the right amounts, ozone can sanitize food and drinking water. Studies have shown that injecting small amounts of ozone into filtered tap water can reduce more than 99.99% of food-borne microorganisms such as salmonella and E. coli. It can also remove residue of pesticides from fruits, vegetables, lentils, meat and seafood.

    An ozoniser is a device that generates ozone by charging the air with high voltage electricity. The gas is then either released into the air or water. Ozone improves the quality of indoor air by removing unpleasant odours and killing microbes. When fruits and vegetables are soaked in water infused with ozone, it removes chemicals, bacteria and fungus without hurting their nutritional content. In the process, the food tastes better and lasts longer. 

    On the flip side, some scientific studies suggest that the amount of ozone needed to effectively kill bacteria and remove odours can be harmful to humans and hence should be used with care.

MOTIVATIONAL STORY

The tomato story

     A jobless man applied for the position of 'office boy' at a very big company. The employer interviewed him, followed by a test of cleaning the floor.
"You are hired," the employer said. "Give me your email address, and I'll send you the application to fill, as well as when you will start."
The man replied, "I don't have a computer, neither an email."
"I am sorry," said the employer, if you don’t have an email, you cannot have the job."
     The man left with no hope. He didn't know what to do, with only ₹100 in his pocket. He then decided to go to the supermarket, bought a 10kg tomato crate, then sold the tomatoes door to door. In less than two hours, he succeeded and doubled his capital. He repeated the operation 3 times and returned home with ₹300. 
     The man realised that he could survive by this way, and started to go everyday earlier and returned late. Thus, his money doubled or tripled everyday. Shortly later, he bought a cart, then a truck and then he had his own fleet of delivery vehicles. Five years later the man's company was one of the biggest food retailers. 
     He started to plan his family's future and decided to have a life insurance. He called an insurance broker and chose a protection plan. When the conversation concluded, the broker asked him his email. The man replied, "I don't have an email."
     The broker replied curiously, "You don't have an email and yet you have succeeded to build an empire. Do you imagine what position you could have if you had an email?"
The man paused for a while and replied, "An office boy!"

Don’t be discouraged if something is not in your favour today. Better opportunities are always waiting ahead.

AN IMPORTANT GLAND IN OUR BODY

Thyroid gland
  The thyroid gland is located in the front of the neck. It has two lobes, one on each side of trachea (or windpipe). The lobes are connected by a thin band of tissue, while a network of blood vessels surrounds the gland. The thyroid takes the iodine from the blood and uses it to make the active hormones thyroxine, also called tetraiodothyronine and triiodothyronine. An inactive form of thyroid hormones is stored inside the lobes in small chambers called follicles.
Thyroid hormones are released into the bloodstream, cells increase the rate at which they convert oxygen and nutrients into energy and heat for the body's use.   During a child's development, thyroid hormones stimulate an increase in growth rate. Release of thyroid hormones also stimulates mental activity and increases the activity of the other hormone-producing glands.

DO YOU KNOW

 Why muscles ache after exercise?

     Whatever you do, you are using your muscles. Not all of them move at once - you have 639 muscles in all - but you would be surprised to know how many of your muscles you use doing something as simple as walking. 

     When your muscles are working, they produce an acid called lactic acid, which makes the muscles feel tired. When you rest, your body gets rid of lactic acid, and you don't feel so tired.    

   When you do a lot of hard exercise, like a running race, you may get a cramp, a sharp pain in the muscles you are using the most. Cramp is caused by a big build-up of lactic acid in these muscles, and a lot of rest is needed to get rid of the cramp. So, although exercise, as we know, is good for your body, rest is just as good, and just as important.
