Anaemia – UPSC Prelims

Anaemia: It is a condition in which the number of red blood cells or their oxygen-carrying capacity is insufficient to meet physiologic needs, which vary by age, sex, altitude, smoking, and pregnancy status. Iron deficiency is the most common cause of anaemia, although other conditions, such as folate, vitamin B12 and vitamin A deficiencies, chronic inflammation, parasitic infections, and …

Polar Orbit – UPSC Prelims

Polar Orbit: A polar orbit travels north-south over the poles and takes approximately 90 minutes for a full rotation. These orbits have an inclination near 90 degrees. This allows the satellite to see virtually every part of the Earth as the Earth rotates underneath it. These satellites have many uses such as monitoring crops, global security, measuring ozone concentrations …

Geosynchronous Orbit – UPSC Prelims

Geosynchronous Orbit Geosynchronous satellites are launched into orbit in the same direction the Earth is spinning and can have any inclination. When the satellite is in orbit at a specific altitude (approximately 36,000km above the Earth’s surface), it will exactly match the rotation of the Earth. While, Geostationary orbits fall in the same category as geosynchronous orbits, but with …

Diphtheria

Diphtheria is a severe communicable and bacterial infectious disease that causes inflammation of the mucous membranes by forming a false membrane in the throat which creates a problem while swallowing food and during breathing. It can also damage nerves by a bacterial toxin present in the blood. Currently, this syndrome is rare in developed countries. …
