Urochloa Ramosa
''Urochloa ramosa'', (formerly ''Brachiaria ramosa'') the browntop millet or Dixie signalgrass, is an annual, millet grass belonging to the grass family ( Poaceae). The native range of ''Urochloa ramosa'' is from Africa to tropical and subtropical Asia. Description It has glabrous (hairless) spikelets, are about long, the upper of each pair on a pedicel (stalk) about as long as the spikelet. The spikelets are more often slightly or distinctly puberulent and pedicels are often shorter. Plants found in Malesia and Australia always have shorter spikelets (only up to 3 mm long). Growth Seed germination can happen in up to 5 days and the rapidly growing crop can then be harvested in the next two months. Its fine stems and leaves allow the plant to dry sufficiently to be used as a dry hay product. Taxonomy It was originally published as ''Brachiaria ramosa'' in D.Oliver & auct. suc. (eds.), Fl. Trop. Afr. 9: 542 in 1919, before being renamed and published and described by botan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cotton
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus '' Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants date ...

Environmental Remediation
Environmental remediation deals with the removal of pollution or contaminants from environmental media such as soil, groundwater, sediment, or surface water. Remedial action is generally subject to an array of regulatory requirements, and may also be based on assessments of human health and ecological risks where no legislative standards exist, or where standards are advisory. Remediation standards In the United States, the most comprehensive set of Preliminary Remediation Goals (PRGs) is from the Environmental Protection Agency (EPA) ''Regional Screening Levels'' (RSLs). A set of standards used in Europe exists and is often called the Dutch standards. The European Union (EU) is rapidly moving towards Europe-wide standards, although most of the industrialised nations in Europe have their own standards at present. In Canada, most standards for remediation are set by the provinces individually, but the Canadian Council of Ministers of the Environment provides guidance at a fed ...

Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...

Lead
Lead is a chemical element with the Symbol (chemistry), symbol Pb (from the Latin ) and atomic number 82. It is a heavy metals, heavy metal that is density, denser than most common materials. Lead is Mohs scale of mineral hardness#Intermediate hardness, soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable nuclide, stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and base (chemistry), bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Root-knot Nematode
Root-knot nematodes are plant-parasitic nematodes from the genus ''Meloidogyne''. They exist in soil in areas with hot climates or short winters. About 2000 plants worldwide are susceptible to infection by root-knot nematodes and they cause approximately 5% of global crop loss. Root-knot nematode larvae infect plant roots, causing the development of root-knot galls that drain the plant's photosynthate and nutrients. Infection of young plants may be lethal, while infection of mature plants causes decreased yield. Economic impact Root-knot nematodes (''Meloidogyne'' spp.) are one of the three most economically damaging genera of plant-parasitic nematodes on horticultural and field crops. Root-knot nematodes are distributed worldwide, and are obligate parasites of the roots of thousands of plant species, including monocotyledonous and dicotyledonous, herbaceous and woody plants. The genus includes more than 90 species, with some species having several races. Four ''Meloidogyne'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crop (anatomy)
A crop (sometimes also called a croup or a craw, ingluvies, or sublingual pouch) is a thin-walled expanded portion of the alimentary tract used for the storage of food prior to digestion. This anatomical structure is found in a wide variety of animals. It has been found in birds, and in invertebrate animals including gastropods (snails and slugs), earthworms, leeches, and insects. Insects Cropping is used by bees to temporarily store nectar of flowers. When bees "suck" nectar, it is stored in their crops. Other Hymenoptera also use crops to store liquid food. The crop in eusocial insects, such as ants, has specialized to be distensible, and this specialization enables important communication between colonial insects through trophallaxis. The crop can be found in the foregut of insects. Birds In a bird's digestive system, the crop is an expanded, muscular pouch near the gullet or throat. It is a part of the digestive tract, essentially an enlarged part of the esopha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mourning Dove
The mourning dove (''Zenaida macroura'') is a member of the dove family, Columbidae. The bird is also known as the American mourning dove, the rain dove, and colloquially as the turtle dove, and was once known as the Carolina pigeon and Carolina turtledove. It is one of the most abundant and widespread of all North American birds and a popular gamebird, with more than 20 million birds (up to 70 million in some years) shot annually in the U.S., both for sport and meat. Its ability to sustain its population under such pressure is due to its prolific breeding; in warm areas, one pair may raise up to six broods of two young each in a single year. The wings make an unusual whistling sound upon take-off and landing, a form of sonation. The bird is a strong flier, capable of speeds up to . Mourning doves are light gray and brown and generally muted in color. Males and females are similar in appearance. The species is generally monogamous, with two squabs (young) per brood. Both p ...

Bird Food
Bird food or bird seed is food (often varieties of seeds, nuts, and/or dried fruits) intended for consumption by wild and domestic birds. While most bird food is fed to commercial fowl (such as chicken or turkey), bird food is also used to feed pet birds or provide a feeding site for wild birds. The various types of bird food reflect the species of bird that can be fed, whether they are carnivores, herbivores, insectivores, nectarivores, etc. Bird food can also differ by the feeding strategies employed by beaks in cracking the seed coat and obtaining the meat of the seed. Black-oil sunflower seeds attract the widest variety of birds, and are commonly used in backyard bird feeders. However, other varieties of seed can help attract specific types of birds to gardens and backyards. In general, mixtures that contain red millet, oats, and other "fillers" are not attractive to most birds, and can lead to waste as the birds sort through the mix, as well as the potential for fun ...
