THREATENING COVID-19

THIS IS -  'Coronavirus'
2K20... What a year! Still more Eight more months to go. It's a hard time right! Our lives are in a hurry. We all wake up every day (not to be sure) and do our assigned work. But suddenly......
 We are just staying in our home don't know what the f**k is happening around us. 

 The whole world is in PANDEMIC now. How and why this happened? From where? And lots and lots of questions are going in our heads. 


What does the word Corona mean? It's a Latin word meaning crown or wreath.

HISTORY

It is first discovered in 1930 when the acute respiratory infections of chickens. In the 1940s two more animal coronavirus was lonesome. Then human coronavirus was discovered in the 1960s and isolated from a boy a novel common cold virus B814 and then many similar viruses like  SARS-CoV in 2003, HCoV NL63 in 2004, HCoV HKU1 in 2005, MERS-CoV in 2012 are discovered. But now we have one of the dangerous ones SARS-CoV-2 in 2019. 




STRUCTURE 

SARS‑CoV‑2 genetically clusters with the genus Betacoronavirus and is 96 percent identical at the whole genome level to other bat coronavirus samples and 92 percent identical to pangolin coronavirus.




Coronaviruses contain a positive-sense, single-stranded RNA genome. The genome organization for a coronavirus is 5′-leader-UTR-replicase/transcriptase-spike (S)-envelope (E)-membrane (M)-nucleocapsid (N)-3′UTR-poly (A) tail. and a complex biological process goes on and we are not looking into it deeply.
Its typical structure made it a tough one to encounter and researchers from all over the world are working hard to find the vaccine.

TRANSMISSION 

The virus is spread primarily by close contact and by small droplets produced during coughing, sneezing, and talking. Studies found that it can spread up to 6 meters.
As these droplets when present on the surface; the people get infected when they touch the surface and then their eyes, nose, or mouth. The virus survives for hours to days on surfaces. Coronavirus mainly targets the epithelial cells (a basic type of animal issue ) and infects via the aerosol route.

CASES AND DEATHS :

  Till now
             Confirmed cases - 31,57,459.
             Deaths -  2,19,611.
             Recovered - 9,57,094.

It's such a deadly virus right! Damn... Let us hope for the betterment of mankind.


SYMPTOMS

 Common symptoms are fever, tiredness, and dry cough.
Some people may experience:
                                                Aches and pains.
                                                Nasal congestion.
                                                Runny nose.
                                                Sore throat.
                                                Diarrhea.

PREVENTION 

  1. Clean your hands using soap and water, or an alcohol-based hand rub.
  2. Don’t touch your eyes, nose, or mouth.
  3. Keep a safe distance from others.
  4. During cough or sneeze cover your nose and mouth with your bent elbow or a tissue.
  5. Follow the directions of your local health authority.

Quantum Radar

Radar is an acronym for "radio detection and ranging". We have Bistatic radar, Continuous-wave radar Doppler radar, and more and more. As there is development in every technology. There's a new development on the radar which is based on the quantum-mechanical effects called the Quantum Radar . Before we see about the quantum radar we would like to define a term called quantum entanglement. It is a physical marvel whereby two particles stay interconnected, sharing physical characteristics paying little mind to how far separated they are from each other. To know more check - How it works Extensively, a quantum radar can be viewed as a gadget working in the microwave extend, which exploits quantum highlights, from the perspective of the radiation source and additionally the yield discovery, and can beat an old-style partner. One methodology depends on the utilization of information quantum connections (specifically, quantum ensnarement) joined with a reasonable interferome...

Space Debris - Junk in Space

Space Space Space!!!   The terms Solar solstice and Space elevator were explained in previous blogs. Now we are gonna see about Space debris. Have you ever wondered, what happens to the parts of a rocket that fall off??? What does actually space debris mean??? Is there any possibility to clean up space debris??? If so, How??? These are some general questions that will revolve around everyone's mind...Now you will get some clarity about those questions, let us move into the topic... What is Space debris? Space debris ( known as space junk), is a piece of machinery or junk left by humans in space, generally in earth's orbit, which are no longer useful. These materials can be of large objects such as heavy satellites that have failed or left in the earth's orbit after the mission. It can also be small things like paint flecks, solidified liquids, and junks that have fallen from a rocket. Some of the human-made junks have been left on the moon too. Most of the junks are present...
