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.

LETS KNOW THE HISTORY OF ENGINEERS DAY

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). Sir M.V completed his schooling in Chikkaballapur and joined Central College, Bengaluru, and completed a B.A degree. In Pune, he studied Civil Engineering at the College of Engineering, Pune. 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.

WHY DO MOSQUITOES NOT BITE WHEN AC or FAN IS ON?

September 11, 2020 0


The reason is the temperature range. The mosquitoes will breed and spread in a temperature range of 25–38 degrees Celsius. If the temperature is lower than 24 or 25 degrees Celsius, then, mosquitoes become inactive. Likewise, if the temperature exceeds the 40 degrees mark, then, mosquitoes disappear as well. Therefore, it’s to do with the temperature range.

Several other reasons:

  1. Mosquitoes detect heat. If you lower your skin temperature then you are not identified as easily.
  2. Air conditioning creates a breeze, this makes it harder to fly. This is the same reason why mosquitoes do not tend to bite you when it is windy.
  3. Air conditioning dries the air, Mosquitoes seek out moist locations.
  4. Usually Air conditioning requires doors closed. Mosquitoes thus find it hard to enter the home.
  5. A breeze blows carbon dioxide around, thus making it hard for mosquitoes to identify the source.
