Balsa III Balsic 1421 Eng
''Ochroma pyramidale'', commonly known as balsa, is a large, fast-growing tree native to the Americas. It is the sole member of the genus ''Ochroma'', and is classified in the subfamily Bombacoideae of the mallow family Malvaceae. The tree is famous for its wide usage in woodworking, due to its softness and its high strength compared to its low density. The name ''balsa'' is the Spanish word for "raft" and the Portuguese word for ferry. A deciduous angiosperm, ''Ochroma pyramidale'' can grow up to 30 m tall, and is classified as a hardwood despite the wood itself being very soft; it is the softest commercial hardwood and is widely used because of its light weight. Balsa trees grow extremely fast, often up to 27 metres in 10–15 years, and do not usually live beyond 30 to 40 years. In terms of volume (as opposed to height) they may be the fastest growing tree known; Streets mentions one individual which grew tall and diameter at breast height during a period of fifteen mo ...

Chevrolet Corvette
The Chevrolet Corvette is a line of American two-door, two-seater sports cars manufactured and marketed by General Motors under the Chevrolet marque since 1953. Throughout eight generations, indicated sequentially as C1 to C8, the Corvette is noted for its performance, distinctive styling, lightweight fiberglass or composite bodywork, and competitive pricing. The Corvette has had domestic mass-produced two-seater competitors fielded by American Motors Corporation, American Motors, Ford Motor Company, Ford, and Chrysler; it is the only one continuously produced by a United States auto manufacturer. It serves as Chevrolet's halo car. In 1953, GM executives accepted a suggestion by Myron Scott, then the assistant director of the Public Relations department, to name the company's new sports car after the corvette, a small, maneuverable warship. Initially, a relatively modest, lightweight 6-cylinder, 6cylinder convertible, subsequent introductions of V8 engine, V8 engines, competitive ...

Wood Grain
Wood grain is the longitudinal arrangement of wood fibers or the pattern resulting from such an arrangement. It has various derived terms refer to different aspects of the fibers or patterns. Wood grain is important in woodworking and it impacts aesthetics. Definition and meanings Wood grain is the longitudinal arrangement of wood fibers or the pattern resulting from such an arrangement. R. Bruce Hoadley wrote that ''grain'' is a "confusingly versatile term" with numerous different uses, including the direction of the wood cells (e.g., ''straight grain'', ''spiral grain''), surface appearance or figure, growth-ring placement (e.g., ''vertical grain''), plane of the cut (e.g., ''end grain''), rate of growth (e.g., ''narrow grain''), and relative cell size (e.g., ''open grain'').Hoadley, R.

Plantation
Plantations are farms specializing in cash crops, usually mainly planting a single crop, with perhaps ancillary areas for vegetables for eating and so on. Plantations, centered on a plantation house, grow crops including cotton, cannabis, tobacco, coffee, tea, cocoa, sugar cane, opium, sisal, oil seeds, oil palms, fruits, rubber trees and forest trees. Protectionist policies and natural comparative advantage have sometimes contributed to determining where plantations are located. In modern use, the term usually refers only to large-scale estates. Before about 1860, it was the usual term for a farm of any size in the southern parts of British North America, with, as Noah Webster noted, "farm" becoming the usual term from about Maryland northward. The enslavement of people was the norm in Maryland and states southward. The plantations there were forced-labor farms. The term "plantation" was used in most British colonies but very rarely in the United Kingdom itself i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf Shape
The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). The edge of the leaf may be regular or irregular, and may be smooth or have hair, bristles, or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deciduous
In the fields of horticulture and botany, the term deciduous () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed Leaf, leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of deciduous in the botanical sense is evergreen. Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer, deciduous teeth (baby teeth) in some mammals (including humans); or decidua, the uterine lining that sheds off after birth. Botany In botany and horticulture, deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their Leaf, leaves for part of the year. This process is called abscission. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evergreen
In botany, an evergreen is a plant which has Leaf, foliage that remains green and functional throughout the year. This contrasts with deciduous plants, which lose their foliage completely during the winter or dry season. Consisting of many different species, the unique feature of evergreen plants lends itself to various environments and purposes. Evergreen species There are many different kinds of evergreen plants, including trees, shrubs, and vines. Evergreens include: * Most species of conifers (e.g., pine, Tsuga, hemlock, spruce, and fir), but not all (e.g., larch). * Live oak, holly, and "ancient" gymnosperms such as cycads * Many woody plants from frost-free climates * Rainforest trees * All eucalypts * Lycopodiopsida, Clubmosses and relatives * Most bamboos The Latin binomial term , meaning "always green", refers to the evergreen nature of the plant, for instance: :''Cupressus sempervirens'' (a cypress) :''Lonicera sempervirens'' (a honeysuckle) :''Sequoia sempervirens'' ...

Olingo
The genus ''Bassaricyon'' consists of small Neotropical procyonids, popularly known as olingos (), cousins of the raccoon. They are native to the rainforests of Central and South America from Nicaragua to Peru. They are arboreal and nocturnal, and live at elevations from sea level to . Olingos closely resemble another procyonid, the kinkajou, in morphology and habits, though they lack prehensile tails and extrudable tongues, have more extended muzzles, and possess anal scent glands. However, the two genera are not sisters. They also resemble galagos and certain lemurs. Species There is disagreement on the number of species in this genus, with some taxonomists splitting the populations into as many as five species (adding ''B. pauli'' to the list below), two species (dropping ''B. medius'' and ''B. neblina''), or just a single species (''B. gabbi''). Until recently, only the northern olingo (''B. gabbii'') was particularly well-known, and it was usually confusingly referred t ...

Kinkajou
The kinkajou ( /ˈkɪŋkədʒuː/ ''KING-kə-joo''; ''Potos flavus'') is a tropical rainforest mammal of the family Procyonidae related to olingos, coatis, raccoons, and the ringtail and cacomistle. It is the only member of the genus ''Potos'' and is also known as the "honey bear" (a name that it shares with the unrelated sun bear). Though kinkajous are arboreal, they are not closely related to any other tree-dwelling mammal group (primates, some mustelids, etc.). Native to Mexico, Central and South America, this mostly frugivorous mammal is seldom seen by people because of its strict nocturnal habits. However, it is hunted for the pet trade, its skin (to make wallets and horse saddles), and its meat. The species has been included in Appendix III of CITES by Honduras, which means that exports from Honduras require an export permit, and exports from other countries require a certificate of origin or of re-export. They may live up to 40 years in captivity. Etymology The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capuchin Monkey
The capuchin monkeys () are New World monkeys of the subfamily Cebinae. They are readily identified as the "Street organ, organ grinder" monkey, and have been used in many movies and television shows. The range of capuchin monkeys includes some tropical forests in Central America and South America as far south as northern Argentina. In Central America, where they are called white-faced monkeys ("carablanca"), they usually occupy the wet lowland forests on the Geography of Costa Rica, Caribbean coast of Costa Rica Geography of Panama, and Panama and deciduous dry forest on the Pacific coast. Etymology The word "capuchin" derives from the Order of Friars Minor Capuchin, who wear brown robes with large hoods. When Portuguese maritime exploration, Portuguese explorers reached the Americas in the 15th century, they found small monkeys whose coloring resembled these friars, especially when in their robes with hoods down, and named them capuchins. When the scientists described a speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cork (material)
Cork is an impermeable buoyant material. It is the phellem layer of bark tissue which is harvested for commercial use primarily from '' Quercus suber'' (the cork oak), which is native to southwest Europe and northwest Africa. Cork is composed of suberin, a hydrophobic substance. Because of its impermeable, buoyant, elastic, and fire retardant properties, it is used in a variety of products, the most common of which is wine stoppers. The montado landscape of Portugal produces approximately half of the cork harvested annually worldwide, with Corticeira Amorim being the leading company in the industry. Cork was examined microscopically by Robert Hooke, which led to his discovery and naming of the cell. Cork composition varies depending on geographic origin, climate and soil conditions, genetic origin, tree dimensions, age (virgin or reproduction), and growth conditions. However, in general, cork is made up of suberin (average of about 40%), lignin (22%), polysaccharid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
