The Modified Mercalli intensity scale (MM, MMI, or MCS) measures the effects of an earthquake at a given location. This is in contrast with the seismic magnitude usually reported for an earthquake. Magnitude scales measure the inherent force or strength of an earthquake – an event occurring at greater or lesser depth.
Central Greenland ice core reconstructed temperature up to mid-19th century. In climatology, the 8.2-kiloyear event was a sudden decrease in global temperatures that occurred approximately 8,200 years before the present, or c. 6,200 BC, and which lasted for the next two to four centuries.
The eigenvalue and eigenvector problem can also be defined for row vectors that left multiply matrix . In this formulation, the defining equation is. where is a scalar and is a matrix. Any row vector satisfying this equation is called a left eigenvector of and is its associated eigenvalue.
The buildings were square and 207 ft (63 m) on each side but had chamfered 6 ft 11 in (2.11 m) corners, making each building's exterior roughly 210 ft (64 m) wide. [22] One World Trade Center (WTC 1), the "North Tower", was, at 1,368 ft (417 m), six feet taller than Two World Trade Center (WTC 2), the "South Tower", which was 1,362 ft (415 m) tall.
Chromosome 2 is one of the twenty-three pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 2 is the second-largest human chromosome, spanning more than 242 million base pairs [4] and representing almost eight percent of the total DNA in human cells. Chromosome 2 contains the HOXD homeobox gene cluster.
In 1877, German physiologist Wilhelm Kühne (1837–1900) first used the term enzyme, which comes from Ancient Greek ἔνζυμον (énzymon) 'leavened, in yeast', to describe this process. [11] The word enzyme was used later to refer to nonliving substances such as pepsin , and the word ferment was used to refer to chemical activity produced ...
