In mathematics, an empty product, or nullary product or vacuous product, is the result of multiplying no factors.It is by convention equal to the multiplicative identity (assuming there is an identity for the multiplication operation in question), just as the empty sum—the result of adding no numbers—is by convention zero, or the additive identity.
The Braille pattern dots-0 ( ⠀), also called a blank Braille pattern, is a 6-dot or 8-dot braille cell with no dots raised. It is represented by the Unicode code point U+2800, and in Braille ASCII with a space.
The microelectrode method for measuring pH i consists of placing a very small electrode into the cell’s cytosol by making a very small hole in the plasma membrane of the cell. [19] Since the microelectrode has fluid with a high H+ concentration inside, relative to the outside of the electrode, there is a potential created due to the pH ...

These mistakes are usually the result of confusion between Null and either 0 (zero) or an empty string (a string value with a length of zero, represented in SQL as ''). Null is defined by the SQL standard as different from both an empty string and the numerical value 0, however. While Null indicates the absence of any value, the empty string ...
Empty sella syndrome is the condition when the pituitary gland shrinks or becomes flattened, filling the sella turcica with cerebrospinal fluid instead of the normal pituitary. [2] It can be discovered as part of the diagnostic workup of pituitary disorders, or as an incidental finding when imaging the brain.
Students often cannot buy these things separately, and often the one-time-use supplements destroy the resale value of the textbook. [ 16 ] According to the Student PIRGs, the typical bundled textbook costs 10%–50% more [ clarification needed ] than an unbundled textbook, and 65% of professors said they "rarely" or "never" use the bundled ...
