Hi,

#8461 When was Antiseptic initiated?

#8462. Name the medication used to reduce pain, fever, or inflammation. Specific inflammatory conditions which aspirin is used to treat include Kawasaki disease, pericarditis, and rheumatic fever.

It is also used long-term to help prevent further heart attacks, ischaemic strokes, and blood clots in people at high risk. For pain or fever, effects typically begin within 30 minutes. It is a nonsteroidal anti-inflammatory drug (NSAID) and works similarly to other NSAIDs but also suppresses the normal functioning of platelets.

Hi,

#8491. When is the 'International Albinism Awareness Day' celebrated? (International Albinism Awareness Day (IAAD) is celebrated annually to celebrate the human rights of persons with albinism worldwide.

Albinism is a congenital condition characterized in humans by the partial or complete absence of pigment in the skin, hair and eyes. Albinism is associated with a number of vision defects, such as photophobia, nystagmus, and amblyopia. Lack of skin pigmentation makes for more susceptibility to sunburn and skin cancers.

#8492. When is the 'International Tea Day' observed? (The concerning resolution was adopted on December 21, 2019 and calls on the United Nations Food and Agriculture Organization (FAO) to lead the observance of the Day.

The International Tea Day aims to raise awareness of the long history and the deep cultural and economic significance of tea around the world. The goal of the day is to promote and foster collective actions to implement activities in favour of the sustainable production and consumption of tea and raise awareness of its importance in fighting hunger and poverty.)

An International Tea Day has been celebrated on December 15, since 2005, in tea producing countries like India, Sri Lanka, Nepal, Vietnam, Indonesia, Bangladesh, Kenya, Malawi, Malaysia, Uganda and Tanzania. International Tea Day aims to draw global attention of governments and citizens to the impact of the global tea trade on workers and growers, and has been linked to requests for price supports and fair trade.

Hi,

#8495. Name the English engineer, inventor (1 June 1907 – 8 August 1996) and Royal Air Force (RAF) air officer. He is credited with inventing the turbojet engine. A patent was submitted by Maxime Guillaume in 1921 for a similar invention; however, this was technically unfeasible at the time. His jet engines were developed some years earlier than those of Germany's Hans von Ohain, who designed the first-to-fly (but never operational) turbojet engine.

#8496. Name the American physicist  (July 28, 1915 – January 27, 2015). He worked on the theory and application of the maser, for which he obtained the fundamental patent, and other work in quantum electronics associated with both maser and laser devices. He shared the 1964 Nobel Prize in Physics with Nikolay Basov and Alexander Prokhorov.

Hi,

#8497.  Name the American inventor, electrical engineer and entrepreneur (May 3, 1922 – April 15, 2019) who was awarded 76 US patents as an individual or as part of a team, as well as many corresponding patents. His patents have had an impact relating to home washing machines and the preparation of food in both the Quick Service Restaurant (QSR) industry and fine dining. Technologies He developed while an engineer at General Electric are still in use after more than fifty years. His patent for the modern "Washing Machine" (US 3257830 A), licensed in 1965 to General Electric has been referenced in over 40 subsequent patents.

He also invented new ways to cook and hold food, including the Collectramatic, the first pressurized fryer that did not require interrupting production to frequently filter shortening while cooking. He also invented Controlled Vapor Technology, a patented cooking method that uses water vapor to prepare and safely hold food.

#8498. In what later became the United States, the pointed lightning rod conductor, also called a lightning attractor or Franklin rod, was invented by Benjamin Franklin as part of his groundbreaking exploration of electricity. Although not the first to suggest a correlation between electricity and lightning, Franklin was the first to propose a workable system for testing his hypothesis. Franklin speculated that, with an iron rod sharpened to a point, "The electrical fire would, I think, be drawn out of a cloud silently, before it could come near enough to strike." Franklin speculated about lightning rods for several years before his reported kite experiment.

In which year was it?
