John Miers (botanist)
John Miers, FRS FLS (25 August 1789 – 17 October 1879. Kensington), knight grand cross of the Order of the Rose, was a British botanist and engineer, best known for his work on the flora of Chile and Argentina. Miers was born in London to a jeweller from Yorkshire, and showed interest in mineralogy and chemistry from an early age. His first published work was a monograph on nitrogen which appeared in the '' Annals of Philosophy'' in 1814. After his marriage in 1818 he travelled to South America to participate in a venture to exploit the mineral resource of Chile, particularly copper. However, after landing in Buenos Aires his wife came down with childbed fever on the trip across country, and he decided not to continue to Chile, instead starting a study of the local flora, which at that time was largely unresearched. In May 1819 Miers arrived in Santiago, Chile, having arranged the clandestine transport of coin presses, and settled at Concón, near Valparaíso. He developed b ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menispermaceae
Menispermaceae (botanical Latin: 'moonseed family' from Greek ''mene'' 'crescent moon' and ''sperma'' 'seed') is a family (biology), family of flowering plants. The alkaloid tubocurarine, a neuromuscular blocker and the active ingredient in the 'tube curare' form of the dart poison curare, is derived from the South American liana ''Chondrodendron tomentosum'', which belongs to this family. Several other South American genera belonging to the family have been used to prepare the 'pot' and 'calabash' forms of curare. The family contains 78 Genus, genera with some 440 species, which are distributed throughout low-lying tropical areas with some species present in temperate and arid regions. Description * Twining, ever-growing and woody climbing plants, winding anti-clockwise (''Stephania'' winds clockwise) and vines; rarely upright shrubs or small trees. Rarer still herbaceous plants or epiphytes (''Stephania cyanantha''), perennial or deciduous, with simple to uni-serrate hairs. * ...

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...

Brown Coal
Lignite (derived from Latin ''lignum'' meaning 'wood'), often referred to as brown coal, is a soft, brown, Combustion, combustible sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35% and is considered the Coal rank, lowest rank of coal due to its relatively low Heat of combustion, heat content. When removed from the ground, it contains a very high amount of moisture, which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. Lignite combustion produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, lignite is the most harmful coal to human health. Depending on the source, various toxic heavy metals, including naturally occurring radioactive materials, may be present in lignite and left over in the coal fly ash produced from its combustion, further increasing health risks.

Bergheim, North Rhine-Westphalia
Bergheim (; Ripuarian language, Ripuarian: ''Berchem'') is a German town, 22 km west of Cologne and the capital of the Rhein-Erft-Kreis (district).
