What actually made Apple a trillion dollar company?

How to prevent raw rice from being destroyed by termites?

Cereals like wheat, rice often get infected by pests like termites and other insects. It is thus significant to know the various ways and manners in which we can avoid this issue. This is how you can save your cereals:

1. Natural Ingredients: Use cloves, cardamom and cinnamon sticks in the jar of rice you have for storage. But do not add a few of these in kilos of rice. 12-15 pieces of these in 1 kg of rice should be a safe ratio.

2. Chemical Compound Addition: The other popular method is the use of boric acid. Boric acid is available in the form of powder or even tablets nowadays. Add it to the raw rice and thoroughly wash it before use.

3. Termites Saving Tablets: 'Paarad ki goli' is a traditional tablet available at pharmacist stores which are used to avoid the raw rice being spoilt by pests. Wash the rice properly, before use in this case too.

Why Dante is considered a great poet?

Dante was truly a great poet. A person of grim melancholy, bitter nature and great solace, he was the one who has given us the marvellous work of his- Divine Comedy. He died at the age of fifty-six and was buried in the city of Ravenna, but his writings make him immortal in our eyes.

Dante's poems were not merely poetic pieces, but they had the harmony of a melodious song. There was rhythm in his poems just like harmony in a song.

Great Works

All the information about him is available either through Divine Comedy or through the portrait of his. His unfathomable song, which is his poem himself, is a masterpiece and no one else could have written it with such magnanimous pictures of Hell, Heaven, and Purgatory. When one is reading about Hell, one feels horrified, while one feels blissful when one reads about Heaven. Thus, Dante has not only presented the Good looking things with clarity but also presented the evil looking things with the same lucidity.

What made Shakespeare the greatest of all writers?

William Shakespeare was truly the greatest of all writers. Probably competing Shakespeare’s talent would be Milton and Dante, but no one else. He is not only a poet who is remembered for his life and works, but he is the one who is remembered for only the magnanimity and grandeur of his works.

This Is What Makes Him the Greatest of All

Versatility

He not only wrote tragedy but also a comedy with equal brilliance. Love stories like Romeo Juliet have given him yet another supremacy too. The King Lear’s plight, the loveliness of Cordelia, the loyalty of Kent, the evil nature of Goneril and Regan, the suspicion and the revenge of Othello, the innocence of Desdemona and what not! He was not only a writer but a portrait painter.

In what ways are women breaking stereotypes?

Women of the contemporary times are not like the ones who used to be confined to the four walls of the house. They are rather breaking stereotypes and carving a niche for themselves. Not only the family which they belong to but they are making the whole country proud of them.

Stepping Out

Earlier women used to be strictly at home. No going out alone except something very urgent takes place. But now, women are moving ahead of men in career and what not!

Taking their Own Decisions

Age is no bar for a woman who wishes to do something. I have read an interview of a woman who married at the age of 54 because her husband died 2 years ago due to cancer and she could not take care of her health after that alone. Another woman teaches ballad dance to a group of 30 girls daily with all her poise at the age of 85 years.

New Professions

Earlier women used to engage themselves in art and craft, tailoring and weaving. But now women are even employed as cab drivers, bartenders police officers etc.

As an HR of a company, what kind of attitude should I carry at work?

Human Resource manager or HR of a company holds quite a significant role in the overall functionality of the proceedings carried out in an organization. However, an HR sometimes may appear quite different in the other employees' depiction. So, why does it happen? Plainly because the responsibilities the HR person has to carry. But can it be done without being characterized? Here's the answer:

Attitude You Must Carry

• Not To Be Too Close to Anyone In the Office: Human Resource Manager should be someone who alienates himself/herself in the office. This is because, HR is involved in dealing with leave applications, appraisal letters of various employees. The information of which should not be disclosed knowingly or unknowingly to anyone.

Is it true that opportunity knocks only once?

It is a common saying that,” Opportunity seldom knocks twice.” But, it is a saying which I believe is subject to analysis on one’s own.

Opportunity Was for Once Only

Consider the scenario wherein a girl who wants to pursue her dreams of becoming an IAS Officer. Her parents want her to be settled in her life, but at the same time, they wish her to be married at the right age, as they say in India depending upon the religion she belongs to.

Upon much persuasion by her parents, the girl pleads with her parents to give her one single chance in order to live up to her dream of becoming an IAS officer. She gives her best shot, but to her dismay, she does not qualify the Interview of the process and she gets married as per her parent’s wishes.

In this case, the opportunity did not knock twice and she spent years thinking what would her life be had she qualified the examination in the second attempt, but life did not grant her the second attempt.

Opportunity Knocked Another Time

Consider the previous scenario with a bit of alteration, if the girl who got married, was blessed with a supportive husband who supported her in fulfilling her dreams by letting her study post marriage to become an IAS officer. In this case, in her second attempt, she qualified the examination- all stages and became an IAS officer.

Does over thinking cause depression?

While over thinking is a major cause of depression, it is also an after – effect. Imagine what would happen if you shut yourself in a room for days together, and just think about yourself; about your future; about your well being; about your state of mind in future and so on. What would happen then? Will you be able to go to a party or go for a movie? Probably No. In fact, you will feel listless and uninterested in anything.

Is Over Thinking the Only Cause of Depression?

While overthinking is one of the causes of depression, it is not the only cause of mood disorder. There may be other causes like hereditary factors, lack of pleasant company and so on. Is everyone who thinks a lot gets into the trap of depression?

How to wash winter clothes at home dry rather than get them cleaned from the market?

Although, you can easily wash winter clothes at home if you know the right method because if handled by an amateur, things may go wrong and you end up damaging your favorite woolens.

What to Buy?

Nowadays, I see a number of mild liquid detergents Ezee, Safewash, etc. placed on the shelves of a super market close to my house. A few drops of such liquids are enough to get the job done.

Steps To Follow

• Fill a half bucket with fresh running water. Do not fill it with warm water as it may lead to loosening of the fabric threads and even fading of the cloth's color.
• Add Ezee or Safe wash or Genteel according to the number of clothes you are putting in. For half a bucket water, one lid of the bottle should be enough.
• Soak the dirty winter clothes in that detergent mixture for 30 minutes.

Why is cow milk preferred over Buffalo milk by most fitness freaks?

Our grandmothers have been giving us various ‘Dadiji Ke Nuskhe’ since ages, most of which stick to the benefits of cow milk over buffalo milk and cow ghee over buffalo ghee.

Benefits of Cow Milk Over Buffalo Milk

• Less Fattening: Cow milk tends to have a higher water content as compared to buffalo milk. This is because about 87 percent of cow milk is water. Due to this, it tends to be less fattening and also it induces less sleep than buffalo milk does. It is also proven to reduce obesity in children because it is low in cholesterol and calories. Statistics say that 100ml of cow’s milk contains 70Kcals whereas 100ml of buffalo’s milk contains 100Kacls.
• Nutritious: Cow's milk is rich in a wide variety of minerals like Calcium, Vitamin D and Proteins. It is beneficial for healthy bones and teeth. Cow's milk also ensures protection from thyroid diseases and cardiovascular health.

How do bats use sound to locate their prey?

Bats are mammals which use sound ways to locate their prey. They do so by a scientific technique called 'Echolocation'. This is because they are nocturnal mammals that have weak eyesight. They use their ears more than any other mammal.

Echolocation

• It is defined as the use of sound waves and echoes to determine the location of objects in space. Bats use this mechanism for finding their food. Just as SONAR (Sound Navigation and Ranging) is used in case of big ships, and tanks, similarly, the emission of sound waves helps bat catch its prey.
• Bats use ultrasonic waves (above 2000 hertz frequency) to catch their prey.
• Most bats produce a complicated sequence of calls, combining Constant Frequencies and Modulating frequency components. Their sounds are reflected in the environment, hitting various objects and returning to the bat as echoes.
• The echo signals enable the bat to judge the whereabouts of the surroundings and form some sort of mental image of it. Now, in order to reach its prey (about which a mental image has already been formed), bats continuously hurl and glide in curved flight trajectories, using large movements to propel themselves.
• Not only a vague judgment exists, but Bats have some navigational ability to measure how fast the flight angle is changing as they approach their targeted prey also.

Who were the major rulers of Gupta Dynasty?

The Golden Age or The most flourishing age, Gupta Dynasty witnessed some of the greatest rulers in 320-550 CE.

• Initiator: The Gupta Dynasty was started by Sri Gupta who ruled in c. late 3rd century (probably from 240-280 CE).
• Ghatotkash: Srigupta’s son was Ghatotkash who does not have any major achievements to his name.
• Chandragupta I: Ghatotkash was followed by Chandragupta I(320- 335 CE), who was the first sovereign ruler of this empire. He married Licchhavi Princess Kumaradevi, in order to expand his empire through whatever regions he received in the dowry. At the end of his reign, the boundary of the Gupta Empire had extended to Allahabad.
• Samudragupta: Samudra Gupta was the successor of Chandragupta I. He was not his eldest son but by far the most competent amongst them all by proving himself to be a military genius, a great conqueror and a most successful commander. He remained undefeated throughout his life, so Dr. V.A. Smith has called him ‘Indian Napolean’. He conquered the territories of the rulers of the Ganges-Yamuna-Doab, but not by obtaining in dowry as his father, but by winning in battle through his physical strength and the strength of his military empire.
• Chandragupta II: Samudragupta’s successor Chandragupta II (380 – 414 CE) was a benevolent king, able leader, and skilled administrator. The proof of his benevolence is that many charitable institutions, orphanages, rest houses, and hospitals were opened during his reign. Administrative setup also got some change as the large kingdom of his was divided into smaller provinces and heads were appointed to take care of them. He extended the limits of his empire by marriage alliance and conquests( following the footsteps of his earlier predecessors-Samudragupta and Chandragupta I).

• Kumaragupta I (412-454 A.D.) He did not achieve any military success, and Hunas attacked in his reign.
