The Union Public Service Commission (UPSC; ISO: Saṁgha Loka Sevā Āyoga) is a constitutional body tasked with recruiting officers for All India Services and the Central Civil Services (Group A and B) through various standardized examinations. [1] In 2023, 1.3 million applicants competed for just 1,255 positions. [2]
(As long as the heat transfer requirements are met solid state lasers can run continuously.) In the past, both types of lasers were very bulky because of their need for these huge cooling systems. The only aircraft in which they could fit were the size of jumbo jets. Need for such a system was reinforced during the 2006 Lebanon War.

In engineering, a heat shield is a component designed to protect an object or a human operator from being burnt or overheated by dissipating, reflecting, and/or absorbing heat. [1] The term is most often used in reference to exhaust heat management and to systems for dissipating frictional heat.
The Combined Defence Services Examination (CDS) is a standardised test conducted annually by the Union Public Service Commission (UPSC) for recruitment of officer cadets in the Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA), and Officers Training Academy (OTA).
PDRCs mimic the natural process of radiative cooling, in which the Earth cools itself by releasing heat to outer space (Earth's energy budget), although during the daytime, lowering ambient temperatures under direct solar intensity. [5] On a clear day, solar irradiance can reach 1000 W/m 2 with a diffuse component between 50 and 100 W/m 2.
The key difference between a heat shield and insulating the pipe, through either wrapping or thermal coating, is the air gap that exists between the exhaust and the shield. More recently technology has become available to apply ceramic thermal barrier coatings onto flexible aluminium in order to increase the thermal insulatory properties.
The Surface to Air Missile for Assured Retaliation, or SAMAR is a short range, quick reaction surface-to-air missile system. The Indian Air Force (IAF) Maintenance Command's 7 Base Repair Depot Tughlakabad (BRD) and 11 Base Repair Depot Ojhar, in collaboration with Simran Flowtech Industries and Yamazuki Denki, two Indian private sector companies, created the SAMAR system.
