Fortune 500

The Fortune 500 is an annual list compiled and published by Fortune magazine that ranks 500 of the largest United States corporations by total revenue for their respective fiscal years. The list includes publicly held companies, along with held companies for which revenues are publicly available; the concept of the Fortune 500 was created by Edgar P. Smith, a Fortune editor, the first list was published in 1955; the Fortune 500 is more used than its subset Fortune 100 or superset Fortune 1000. The Fortune 500, created by Edgar P. Smith, was first published in 1955; the original top ten companies were General Motors, Jersey Standard, U. S. Steel, General Electric, Chrysler, Gulf Oil, Mobil and DuPont; the original Fortune 500 was limited to companies whose revenues were derived from manufacturing and energy exploration. At the same time, Fortune published companion "Fortune 50" lists of the 50 largest commercial banks, life insurance companies and transportation companies. Fortune magazine changed its methodology in 1994 to include service companies.

With the change came 291 new entrants to the famous list including three in the Top 10. There is a lag in creating the list, so for example, the 2019 Fortune 500 is based on each company's financial years ending in late 2018, or early 2019; as of 2019, the Fortune 500 companies represent two-thirds of the United States's Gross Domestic Product with $13.7 trillion in revenue, $1.1 trillion in profits, $22.6 trillion in total market value. These numbers account for 17% of the gross world product; the companies collectively employ a total of 28.7 million people worldwide, or 0.4% of the Earth's total population. 40 under 40 Fortune Global 500 Fortune India 500 Fortune 1000 List of largest companies in the United States by revenue List of largest companies by revenue List of Fortune 500 computer software and information companies List of women CEOs of Fortune 500 companies Forbes Global 2000 Total Fortune 1000 companies by urban area list Official website Full list of Fortune 500 companies: 1955–2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019

Mimetes saxatilis

Mimetes saxatilis or limestone pagoda is an evergreen, upright branching shrub of 1–2¼ m high, assigned to the family Proteaceae. The oval leaves are 3½–5 cm long and 1½–3 cm wide with a blunt, reddish tip or with three crowded teeth, it has cylinder-shaped inflorescences topped by a crest of green leaves, further consisting of heads with 12-22 individual bright yellow flowers, each in the axil of a flat, green leaf. It is an endemic species, restricted to limestone outcrops in the Agulhas plains in the south of the Western Cape province of South Africa, it is considered an endangered species. Flowering may occur between July and December, but is unreliable in its timing, dependent on sufficient moisture availability. Mimetes saxatilis is an evergreen, upright branching shrub of 1–2¼ m high, its branches are ½–1 cm thick densely felty becoming hairless. After the leaves are shed, cospicuous marks remain; the leathery leaves are alternately set, at a slight upward angle and somewhat overlapping and lack both stipules and a leaf stalks.

The leaves are elliptic to broadly oval, 3½–5 cm long and 1½–3 cm wide with an entire margin and a blunt thickened tip or with three crowded teeth, with a row of hairs along the rim and an felty hairless surface. The inflorescences at the top of the shoots are cylinder-shaped, 5–10 cm long and 5–6 cm in diameter below a crest of green, oval or elliptic, more or less upright leaves; the flower heads consist of fourteen to twenty two individual flowers and are subtended by an ordinary, green leaf. The outer whorl of bracts that encircle the flower heads are loosely arranged, oval to broadly lance-shaped with a pointy tip, 1–2½ cm long and 6–8 mm wide, with a hairless surface except for a row of hairs along the edge; the bracts on the inside of the head are 1 1/4 -- 2 1/2 cm long and 1/4 -- 1/2 cm wide. The bract that subtend the individual flower is lance-shaped, 1¼–2¼ cm long and 1–2 mm wide, with densely silky margins; the yellow 4-merous perianth is 3–3½ cm long. The lower part called tube, that remains merged when the flower is open, is about 2 mm long inflated, hairless.

The four segments in the middle part, have some felty hairs. The segments in the upper part, which enclosed the pollen presenter in the bud, are boat-shaped, line-shaped with a pointy tip in outline, about 5 mm long, with a few scattered hairs; the four anthers lack a filament and are directly connected to the limbs. From the centre of the perianth emerges a slender style of 3–5 cm long, pale yellow near the pollen presenter; the thickened part at the tip of the style called pollen presenter has a ring at its base, is squared cylinder-shaped in the middle and pointy egg-shaped at the tip. The 1 mm long ovary is egg-shaped, finely silky hairy, is subtended by four pointy, awl- to line-shaped scales of about 2 mm long; the ovary develops into a cylinder-shaped fruit of 6–8 mm long and 3–4 mm in diameter. The limestone pagoda can be distinguished from other Mimetes species by the pale yellow colour of the involucral bracts, that are hairless except for a hairy fringe, the large number of yellow flowers per head, each with a yellow style.

The pollen presenter has a typical shape, a squared cylinder at its base and pointy egg-shaped at the tip. Only two other Mimetes species are yellow-flowered; the golden pagoda M. chrysanthus, has 25–35 individual flowers per head and its involucral bracts are woolly at base. The flower heads of the small cryptic pagoda M. palustris contain three to six individual flowers, the leaves in the inflorescence are overlapping, not patent as in both larger species. The limestone pagoda was first collected by Rudolf Schlechter in 1896 from the neighborhood of Elim, who called it Mimetes saxatilis without giving a proper description; this was published by Edwin Percy Phillips in 1911. No synonyms are known; the species name saxatilis is a Latin word that means "that lives amongst rocks". Mimetes saxatilis can be found in an 100 km long, narrow strip along the south coast of about 3 km wide between Franskraal in the west and Struisbay, several km east of Cape Agulhas, from there in a narrow strip inland to around Bredasdorp.

It occurs from sea level to at most 180 m. It only derived alkaline soils, it seems to do best in crevices where the rock is bare. It grows together with other Proteacea that prefer limestone, including Leucospermum patersonii, Protea obtusifolia and Leucadendron meridianum. Flowers may open anywhere between July and December, but this seems to depend on the availability of sufficient moisture. Over most of its distribution, the average annual precipitation is about 400 mm; the fruits are ripe about 9 months after flowering. The limestone pagoda is considered an endangered species due to the limited areas where its populations occupy 62 km2 within a distribution area of 215 km2, the continuing decline of its five known subpopulations as a result of ongoing urban sprawl and competition by invasive plant species, it is under threat because alien ants like Linepithema humile, destroy the nests of the indigenous ants, unlike the native ants eat the elaiosomes where the seed has fallen, so that it is not protected against fire and can be found and eaten by mice and birds.

XHTLAX-FM is a regional Mexican radio station that serves the area around Tlaxcala, Tlaxcala. It is branded as Radio Altiplano, it is part of CORACYT, the radio and television organization of Tlaxcala, along with TDT, La Televisión de Tlaxcala, XETT-AM 1430 in Tlaxcala and XHCAL-FM 94.3 Calpulalpan. Radio Altiplano signed on March 11, 1986, under an agreement made between the state government and IMER. IMER exited the partnership in 1991 due to budget cuts during the government of Carlos Salinas de Gortari. However, the concession history for Radio Altiplano was only beginning in 1991, as that year, the SCT made available 96.5 MHz in Tlaxcala with the XHTLAX-FM callsign. Radio Altiplano FM, S. A. de C. V. would receive the concession on October 21, 1994
