1 KG MANGO COSTS 2.7 LAKHS

June 20, 2021 1


A couple in Madhya Pradesh has deployed four guards and six dogs to prevent the theft of two mango trees.


The orchardist couple Rani and Sankalp Parihar planted two mango saplings years ago. However, little they had any idea the two mango saplings would develop and bore into unusual ruby-colored mangoes, the Japanese Miyazaki, according to a report in Hindustan Times.

Miyazaki mangoes are said to be one of the most expensive breeds of mangoes in the world. Also known as an egg of the sun, the Miyazaki mangoes sold at 2.70 lakh per kilogram in the international market last year, the daily said citing a Japanese media report.

According to the farmer couple, last year, some thieves broke into their orchards and stole the mangoes after it became locally known that they have started growing this rare fruit. However, the couple could manage to protect the two trees.

Consequently, the couple deployed four guards and six dogs to protect the rare trees and seven mangoes.

Elaborating about how they started growing this rare variety of mango, Parihar said, he was on his way to Chennai to buy some saplings when he met a man on a train, who offered him what later turned out to be Miyazaki. “He offered these saplings to me and asked to take care of these plants like our babies. We planted in the orchard without knowing what variety of mangoes it will produce".

Sankalp has named the mangoes Damini, after the name of his mother.

"Later, we researched about this variety and found the real name. But it is still Damini for me," Parihar told the daily.

Sankalp's wife Rani said many people have shown interest to buy Mirazaki mangoes. She said a Mumbai-based jeweler is ready to pay ₹21,000 for a mango.

However, the couple has decided not to sell the mangoes to anyone yet, and instead, they would grow them.

About Miyazaki mangoes:

The mangoes are grown in Japan's Miyazaki city. The mango is over 350 grams in weight and has a 15% or higher sugar content.

These mangoes are rich in antioxidants and contain beta-carotene and folic acid, which is great for people that need help with tired eyes.

They are grown during the peak harvest between April and August.

DO YOU KNOW? BANANA ARE RADIOACTIVE!

May 17, 2021 0



Bananas are slightly radioactive because they contain potassium and potassium decays. Potassium is a necessary substance for healthy operation of your body. You would have to eat a LOT of bananas just to compete with the natural potassium dose of your body.


Other 'radioactive' potassium-rich foods include spinach, white beans, apricots, salmon, avocados, mushrooms, and yogurt.

No one ever developed radiation sickness from eating bananas.

RESEARCH

  • Yes, you will certainly die from radiation poisoning if you are able to eat 10,000,000 bananas at once. You may also witness chronic symptoms if you eat 274 bananas a day for seven years.
  • Your entire body is made of a lot cells, which are made of a lot of organic molecules, the framework of each of which is made of a lot of carbon. A carbon atom (generally speaking) is found to possess either 12 particles in its nucleus, or 14. Atoms with 12 particles in the nucleus (called C-12) are normal and much more abundant. Those with 14 (called C-14) are radioactive and much less common, but present in some small concentration in any natural carbon sample, including your own body.
  • Now, in relevance to the question, banana has potassium atoms of three kinds: K-39, K-40, and K-41; 39 and 41 are not radioactive. K-40 atoms are those you are interested in. 100 grams of banana have 0.328 grams of potassium, of which 0.012 per cent is K-40. Which is to say 100 grams of banana gives you 0.00003936 grams of K-40.
  • Now, the 0.00003936 grams of K-40 that you did get has a half life of 1.25 billion years, compared to the 5,715-year half life of the C-14 inside you

So you are much, much more radioactive than 100 grams of bananas.

HEALTH BENEFITS OF BANANA

  1. Bananas are respectable sources of vitamin C
  2. Manganese in bananas is good for your skin
  3. Potassium in bananas is good for your heart health and blood pressure
  4. Bananas can aid digestion and help beat gastrointestinal issues
  5. Bananas give you energy – minus the fats and cholesterol​
  6. Bananas are one of the best fruit sources of vitamin B6​

ELECTION INK

April 29, 2021 0



  • Electoral inkindelible inkelectoral stain or phosphoric ink is a semi-permanent ink or dye that is applied to the forefinger (usually) of voters during elections in order to prevent electoral fraud such as double voting. 
  • Election ink uses silver nitrate



COMPOSITION

  • Electoral stain typically contains a pigment for instant recognition, a silver nitrate which stains the skin on exposure to ultraviolet light, leaving a mark that is impossible to wash off and is only removed as external skin cells are replaced.
  •  Industry standard electoral inks contain 10%, 14% or 18% silver nitrate solution, depending on the length of time the mark is required to be visible.

LONGEVITY
  • Election stain typically stays on skin for 72–96 hours, lasting 2 to 4 weeks on the fingernail and cuticle area.
  • The election ink used puts a permanent mark on the cuticle area which disappears only with the growth of new nail.
  • It can take up to 4 months for the stain to be replaced completely by new nail growth.
  • Silver nitrate is an irritant and frequently harmful at 25% solution and above.
  • So, Silver nitrate composition is maintained around 18%.
COLOUR
  • Electoral stain is traditionally violet in colour, before the photosensitive element takes effect to leave a black or brown mark.
INTERNATIONAL USE
  • Afghanistan
  • Albania
  • The Bahamas
  • Algeria
  • Dominica
  • Egypt
  • Guatemala
  • Honduras
  • India
  • Indonesia
  • Iraq
  • Pakistan

M. VISVESVARAYA



Sir Mokshagundam Visvesvaraya, more commonly known as Sir MV (15 September 1860 – 14 April 1962) was an Indian civil engineer and statesman and the 19th Diwan of Mysore, serving from 1912 to 1919. He received India's highest honor, the Bharat Ratna, in 1955. He was knighted as a Knight Commander of the British Indian Empire (KCIE) by King George V for his contributions to the public good. His birthday, 15 September, is celebrated as Engineers' Day in India, Sri Lanka, and Tanzania in his memory. He was the Chief Engineer of Krishna Raja Sagara dam in the north-west suburb of Mysuru city, and also served as one of the Chief Engineers of the flood protection system for the city of Hyderabad.

BIOGRAPHY

Visvesvaraya was born into an Orthodox Mulukanadu Brahmin family in Muddenahalli, Chikkaballapur Dist, during Kingdom of Mysore (now Karnataka).

He first took a job as an assistant engineer with the Public Works Department of Bombay, Nashik Division in Dhule district, and later was invited to join the Indian Irrigation Commission. He implemented an intricate system of irrigation in the Deccan Plateau, and designed and patented a system of automatic weir water floodgates that were first installed in 1903 at Khadakvasla Reservoir near Pune. These gates raised the storage level in the reservoir to the highest level likely to be attained without causing damage to the dam. Based on the success of these gates, the same system was installed at Tigra Dam in Gwalior and Krishna Raja Sagara (KRS) Dam in Mandya/Mysore, Karnataka. In 1906–1907, the Government of India sent him to Aden to study water supply and drainage systems. The project prepared by him was implemented in Aden successfully. Visvesvaraya achieved celebrity status when he designed a flood protection system for the city of Hyderabad. He was instrumental in developing a system to protect the Visakhapatnam port from sea erosion. This dam created the biggest reservoir in Asia when it was built. Visvesvaraya gave his technical advice for the location of Mokama Bridge over Ganga in Bihar. At the time, he was over 90 years old, and was called the "Father of Modern Mysore State".

During his service with the Government of Mysore state, he was responsible (under the patronage of the Mysore government) for the founding of Mysore Soap Factory, Parasitoid Laboratory, Mysore Iron & Steel Works (now known as Viswesvarayya Iron and Steel Limited) in Bhadravathi, Sri Jayachamarajendra Polytechnic Bangalore, Bangalore Agricultural University, the State Bank of Mysore, Century Club, Mysore Chamber of Commerce (Federation of Karnataka Chambers of Commerce & Industry), the Apex Chamber of Commerce in Karnataka, University Visvesvaraya College of Engineering (Bangalore) and numerous other industrial places. He encouraging private investment in the industry during his tenure as Diwan of Mysore. He was instrumental in charting out a plan for road construction between Tirumala and Tirupati. He was known for his sincerity, time management, and dedication to his cause. The Bangalore Press and the Bank of Mysore were established during his tenure. A very important part of his nature was his love for Kannada. He set up Kannada Parishat for the improvement of Kannada. He wanted seminars for Kannada supporters to be instituted and conducted in Kannada itself. Visvesvaraya is known to have designed and planned an entire area of Jayanagar in South Bangalore. The foundation of Jayanagar was laid in 1959. It was one of the first planned neighborhoods in Bangalore and, at the time, the largest in Asia. It is believed that the locality, designed by Visvesvaraya has one of the best-planned layouts in Asia.
