There is quite a bit of confusion in the industry. In computer science, most people loosely consider 1 Gb as 2^30=1073741824 bytes, while the prefix Giga actually means 10^9, or 1,000,000,000.
When we buy a hard disk, we are told (correctly) that it holds 1 Gb. Manufacturers base it on the mathematical definition of Giga and give you 10^9 bytes (less than 1073741824=1Gibibyte, or 1 GiB). This is standard practice in the disk drive industry. For example, a Windows 7 will show a 3 tera byte external disk as having 2.72 TB, or 3,000,557,891 byes, in which case it is actually assuming a TB to mean 2^40 byes (instead of TiB). That's where confusion lies.
Can something be done about it? Yes, it has been done since 2007. The less well-known, but official quantity for 1073741824 bytes is one GiB, proposed by the International Electrotechnical Commission (IEC), adopted by IEEE, EU, and NIST. Similarly, 1 TiB means 2^40=1,099,511,627,776 bytes. The prefixes have been replaced by bi (for binary), so Kibibyte, Mebibyte, Gibibyte, Tebibyte, etc.are used to represent 2^10, 2^20, 2^30, 2^40 bytes. Unfortunately I have yet to see this widely being used, or even known!
La cromatina es una sustancia dentro de un cromosoma que consiste en ADN y proteínas. El ADN lleva las instrucciones genéticas de la célula. Las principales proteínas de la cromatina son las histonas, que ayudan a empaquetar el ADN de una forma compacta que cabe en el núcleo celular. Los cambios en la estructura de la cromatina se asocian con la replicación del ADN y la expresión génica.
Blood forms a spherical shape (perfect circular shape) almost immediately upon separating from the blood source. The spherical shape is caused by the surface tension of the blood. Surface Tension causes the blood drop to pull itself in; both horizontally and vertically.
Shortsightedness refers to the situation where the eyeball becomes to long so therefore light extends the retina and the persons finds it difficult to view things near him.It can be cured by using concave lens
