E-commerce is the activity of electronically buying or selling of products on online services or over the Internet. E-commerce draws on technologies such as mobile commerce, electronic funds transfer, supply chain management, Internet marketing, online transaction processing, electronic data interchange (EDI), inventory management systems, and automated data collection systems. E-commerce is in turn driven by the technological advances of the semiconductor industry, and is the largest sector of the electronics industry.
The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of speech sounds in written form. The IPA is used by lexicographers, foreign language students and teachers, linguists, speech–language pathologists, singers, actors, constructed language creators and translators.
The Romance languages, less commonly Latin or Neo-Latin languages, are the modern languages that evolved from Vulgar Latin between the third and eighth centuries. They are a subgroup of the Italic languages in the Indo-European language family. The six most widely spoken Romance languages by number of native speakers are Spanish, Portuguese, French, Italian, Romanian, and Catalan. Italian is the closest national language to Latin, followed by Spanish, Romanian, Portuguese, and the most divergent being French. Taking into account all the Romance languages, including national and regional languages, Sardinian and Italian are together the least differentiated from Latin, and Occitan is closer to Latin than French. However, all Romance languages are closer to each other than to classical Latin.
The Sirenia, commonly referred to as sea-cows or sirenians, are an order of fully aquatic, herbivorous mammals that inhabit swamps, rivers, estuaries, marine wetlands, and coastal marine waters. The Sirenia currently comprise two distinct families: Dugongidae and Trichechidae with a total of four species. The Protosirenidae and Prorastomidae families are extinct. Sirenians are classified in the clade Paenungulata, alongside the elephants and the hyraxes, and evolved in the Eocene 50 million years ago (mya). The Dugongidae diverged from the Trichechidae in the late Eocene or early Oligocene.
X, or x, is the twenty-fourth and third-to-last letter in the modern English alphabet and the ISO basic Latin alphabet. Its name in English is "ex", plural exes.
Escherichia coli, also known as E. coli, is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms. Most E. coli strains are harmless, but some serotypes (EPEC, ETEC etc.) can cause serious food poisoning in their hosts, and are occasionally responsible for food contamination incidents that prompt product recalls. The harmless strains are part of the normal microbiota of the gut, and can benefit their hosts by producing vitamin K2, and preventing colonisation of the intestine with pathogenic bacteria, having a mutualistic relationship. E. coli is expelled into the environment within fecal matter. The bacterium grows massively in fresh fecal matter under aerobic conditions for 3 days, but its numbers decline slowly afterwards.
Eucalyptus is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including Corymbia, they are commonly known as eucalypts. Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut".
Dugongidae is a family in the order of Sirenia. The family has one surviving species, the dugong, one recently extinct species, Steller's sea cow, and a number of extinct genera known from fossil records.

R.E.M. was an American rock band from Athens, Georgia, formed in 1980 by drummer Bill Berry, guitarist Peter Buck, bassist Mike Mills, and lead vocalist Michael Stipe, who were students at the University of Georgia. Liner notes from some of the band's albums list attorney Bertis Downs and manager Jefferson Holt as non-musical members. One of the first alternative rock bands, R.E.M. was noted for Buck's ringing, arpeggiated guitar style; Stipe's distinctive vocal quality, unique stage presence, and obscure lyrics; Mills's melodic bass lines and backing vocals; and Berry's tight, economical drumming style. In the early 1990s, other alternative rock acts such as Nirvana and Pavement viewed R.E.M. as a pioneer of the genre. After Berry left the band in 1997, the band continued its career in the 2000s with mixed critical and commercial success. The band broke up amicably in 2011 with members devoting time to solo projects after having sold more than 85 million albums worldwide and becoming one of the world's best-selling music acts.
