The cyclic light-dependent reactions occur only when the sole photosystem being used is photosystem I. Photosystem I excites electrons which then cycle from the transport protein, ferredoxin (Fd), to the cytochrome complex, b 6 f, to another transport protein, plastocyanin (Pc), and back to photosystem I. A proton gradient is created across the ...
A journal entry is the act of keeping or making records of any transactions either economic or non-economic. Transactions are listed in an accounting journal that shows a company's debit and credit balances. The journal entry can consist of several recordings, each of which is either a debit or a credit. The total of the debits must equal the ...
A rod cell is sensitive enough to respond to a single photon of light [11] and is about 100 times more sensitive to a single photon than cones. Since rods require less light to function than cones, they are the primary source of visual information at night (scotopic vision). Cone cells, on the other hand, require tens to hundreds of photons to ...
Light exerts physical pressure on objects in its path, a phenomenon which can be deduced by Maxwell's equations, but can be more easily explained by the particle nature of light: photons strike and transfer their momentum. Light pressure is equal to the power of the light beam divided by c, the speed of light.
In mathematics, a function is a rule for taking an input (in the simplest case, a number or set of numbers) [5] and providing an output (which may also be a number). [5] A symbol that stands for an arbitrary input is called an independent variable, while a symbol that stands for an arbitrary output is called a dependent variable. [6]
Gestalt psychology, gestaltism, or configurationism is a school of psychology and a theory of perception that emphasises the processing of entire patterns and configurations, and not merely individual components.
The light is guided down the core of the fiber by an optical cladding with a lower refractive index that traps light in the core through total internal reflection. For some types of fiber, the cladding is made of glass and is drawn along with the core from a preform with radially varying index of refraction.
In 1945, Adler began writing the initial forms of the essays for the Great Ideas and six years and $940,000 more later, on April 15, 1952, the Great Books of the Western World were presented at a publication party in the Waldorf-Astoria Hotel, in New York City. In his speech, Hutchins said, "This is more than a set of books, and more than a ...
