Cogongrass
''Imperata cylindrica'' (commonly known as cogongrass or kunai grass ) is a species of perennial rhizomatous grass native to tropical and subtropical Asia, Micronesia, Melanesia, Australia, Africa, and southern Europe. It has also been introduced to Latin America, the Caribbean, and the southeastern United States. It is a highly flammable pyrophyte, and can spread rapidly by colonizing disturbed areas and encouraging more frequent wildfires. Common names The species is most commonly known in English as "cogongrass", from Spanish ''cogón'', from the Tagalog and Visayan ''kugon''. Other common names in English include ''kunai grass'', ''blady grass'', ''satintail'', ''spear grass'', ''sword grass'', ''thatch grass'', ''alang-alang'', ''lalang grass'', ''cotton wool grass'', and ''kura-kura'' , among other names. Description It grows from 0.6 to 3 m (2 to 10 feet) tall. The leaves are about 2 cm wide near the base of the plant and narrow to a sharp point at the ...

Imperata Cylindrica Bukidnon, Philippines
''Imperata'' is a small but widespread genus of tropical and subtropical grasses, commonly known as satintails. Satintail grass species are perennial rhizomatous herbs with solid, erect stems and silky inflorescences. The best known species is ''Imperata cylindrica'', which is recognized as a devastating noxious weed in many places and cultivated as an ornamental plant in others. The genus is named after Ferrante Imperato, a Renaissance apothecary who lived in Naples in the late-16th and early-17th centuries. His collection included a herbarium. Species , Plants of the World Online accepted the following species: * ''Imperata brasiliensis'' - South + Central America, West Indies, southern Mexico * ''Imperata brevifolia'' - southwestern US ( CA AZ NV UT NM TX) * ''Imperata cheesemanii'' - Kermadec Islands (part of New Zealand) * ''Imperata condensata'' - Argentina, Chile * ''Imperata conferta'' - plumegrass, kunay grass - Southeast Asia, Papuasia, Micronesia * ''Imperata co ...

Castilian Spanish
In English, Castilian Spanish can mean the variety of Peninsular Spanish spoken in northern and central Spain, the standard form of Spanish, or Spanish from Spain in general. In Spanish, the term (Castilian) can either refer to the Spanish language as a whole, or to the medieval Old Spanish, a predecessor to Early Modern Spanish. Terminology The term ''Castilian Spanish'' is used in English for the specific varieties of Spanish spoken in north and central Spain. This is because much of the variation in Peninsular Spanish is between north and south, often imagined as Castilian versus Andalusian. Typically, it is more loosely used to denote the Spanish spoken in all of Spain as compared to Spanish spoken in Latin America. In Spain itself, Spanish is not a uniform language and there exist several different varieties of Spanish; in addition, there are other official and unofficial languages in the country, although Spanish is official throughout Spain.

Triterpenoid
Triterpenes are a class of chemical compounds composed of three terpene units with the molecular formula C30H48; they may also be thought of as consisting of six isoprene units. Animals, plants and fungi all produce triterpenes, including squalene, the precursor to all steroids. Structures Triterpenes exist in a great variety of structures. Nearly 200 different skeletons have been identified. These skeletons may be broadly divided according to the number of rings present. In general pentacyclic structures (5 rings) tend to dominate. Squalene is biosynthesized through the head-to-head condensation of two farnesyl pyrophosphate units. This coupling converts a pair of C15 components into a C30 product. Squalene serves as precursor for the formation of many triterpenoids, including bacterial hopanoids and eukaryotic sterols. Triterpenoids By definition triterpenoids are triterpenes that possess heteroatoms, usually oxygen. The terms ''triterpene'' and ''triterpenoid'' ofte ...

Figure Of Speech
A figure of speech or rhetorical figure is a word or phrase that intentionally deviates from ordinary language use in order to produce a rhetorical effect. Figures of speech are traditionally classified into '' schemes,'' which vary the ordinary sequence of words, and '' tropes,'' where words carry a meaning other than what they ordinarily signify. An example of a scheme is a polysyndeton: the repetition of a conjunction before every element in a list, whereas the conjunction typically would appear only before the last element, as in "Lions and tigers and bears, oh my!"—emphasizing the danger and number of animals more than the prosaic wording with only the second "and". An example of a trope is the metaphor, describing one thing as something that it clearly is not in order to lead the mind to compare them, in "All the world's a stage." Four rhetorical operations Classical rhetoricians classified figures of speech into four categories or :Jansen, Jeroen (2008) Imitatio'' ...

Brush Fire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire( in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurrence of wildfires throughout the history of terrestrial life invites conjecture that fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dominance (ecology)
Ecological dominance is the degree to which one or several species have a major influence controlling the other species in their ecological community (because of their large size, population, productivity, or related factors) or make up more of the biomass. Most ecological communities are defined by their dominant species. *In many examples of wet woodland in western Europe, the dominant tree is alder ('' Alnus glutinosa''). *In temperate bogs, the dominant vegetation is usually species of ''Sphagnum'' moss. *Tidal swamps in the tropics are usually dominated by species of mangrove (''Rhizophoraceae'') *Some sea floor communities are dominated by brittle stars. *Exposed rocky shorelines are dominated by sessile organisms such as barnacles and limpets.

Kunai On Fire
A is a Japanese tool thought to be originally derived from the masonry trowel. The two widely recognized variations of the kunai are short kunai (小苦無 shō-''kunai'') and the big ''kunai'' (大苦無 ''dai-kunai''). Although a basic tool, in the hands of a martial arts expert, the ''kunai'' could be used as a multi-functional weapon. The ''kunai'' is commonly associated with the ninja, who used it to gouge holes in walls. Design A ''Kunai'' normally had a leaf-shaped wrought blade in lengths ranging from 20 cm to 30 cm and a handle with a ring on the pommel for attaching a rope. The attached rope allowed the ''kunais handle to be wrapped to function as a grip, or to be strapped to a stick as a makeshift spear; to be tied to the body for concealment; to be used as an anchor or piton, and sometimes to be used as the Chinese rope dart. Contrary to popular belief, ''kunai'' were not designed to be used primarily as throwing weapons. Instead, ''kunai'' were primar ...

Biomass
Biomass is plant-based material used as a fuel for heat or electricity production. It can be in the form of wood, wood residues, energy crops, agricultural residues, and waste from industry, farms, and households. Some people use the terms biomass and biofuel interchangeably, while others consider biofuel to be a ''liquid'' or ''gaseous'' fuel used for transportation, as defined by government authorities in the US and EU. The European Union's Joint Research Centre defines solid biofuel as raw or processed organic matter of biological origin used for energy, such as firewood, wood chips, and wood pellets. In 2019, biomass was used to produce 57 EJ (exajoules) of energy, compared to 190 EJ from crude oil, 168 EJ from coal, 144 EJ from natural gas, 30 EJ from nuclear, 15 EJ from hydro and 13 EJ from wind, solar and geothermal combined. Approximately 86% of modern bioenergy is used for heating applications, with 9% used for transport and 5% for electricity. Most of the global b ...

Rhizome
In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs underground horizontally. A stolon is similar to a rhizome, but a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, such as in the strawberry plant. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
