Those who wish to adopt the textbooks are required to send a request to NCERT, upon which soft copies of the books are received. The material is press-ready and may be printed by paying a 5% royalty, and by acknowledging NCERT. [11] The textbooks are in color-print and are among the least expensive books in Indian book stores.

The All Terrain Armored Transport (AT-AT) is a quadruped mechanized infantry combat vehicle used by Imperial ground forces.The AT-AT (pronounced either casually as 'at at', or using only the letters ' A.T. A.T. ') [3] was first introduced in The Empire Strikes Back (as the Galactic Empire's main units against Rebel Alliance infantry during the Battle of Hoth) and also appears in Return of the ...
Figure 1. TATA box structural elements. The TATA box consensus sequence is TATAWAW, where W is either A or T. In molecular biology, the TATA box (also called the Goldberg–Hogness box) [1] is a sequence of DNA found in the core promoter region of genes in archaea and eukaryotes. [2]
The imagery of the 9/11 Attacks remains indelible, even as Wednesday marks 23 years since a cloudless morning in New York became a nightmare that shook this country to the core and altered the ...

This move of erasing Mughal history from syllabus attracted severe criticism from ...
By utilizing the interaction picture, one can use time-dependent perturbation theory to find the effect of H 1,I, [15]: 355ff e.g., in the derivation of Fermi's golden rule, [15]: 359–363 or the Dyson series [15]: 355–357 in quantum field theory: in 1947, Shin'ichirÅ Tomonaga and Julian Schwinger appreciated that covariant perturbation ...
In physics, the Heisenberg picture or Heisenberg representation [1] is a formulation (largely due to Werner Heisenberg in 1925) of quantum mechanics in which observables incorporate a dependency on time, but the states are time-independent. It stands in contrast to the Schrödinger picture in which observables are constant and the states evolve ...
Smaller heliostats are used for daylighting and heating. Instead of many large heliostats focusing on a single target to concentrate solar power (as in a solar power tower plant), a single heliostat usually about 1 or 2 square meters in size reflects non-concentrated sunlight through a window or skylight.
