Sesamum Radiatum
''Sesamum radiatum'' is a species of flowering plant in the Pedaliaceae. It is in the same genus as sesame, and is known by the English common names benniseed, black benniseed, black sesame, and vegetable sesame. (While the regular sesame, ''Sesamum indicum'', may have black seeds, also referred to as black sesame, and is a related plant, it is a separate species from ''Sesamum radiatum''.) It is native to west and central Africa, has been cultivated since ancient times in Africa, and is sometimes also used in tropical Asia where it has become naturalized to a small extent. Etymology Benniseed is a portmanteau of both the word ''benne'' and ''seed''. Benne, meaning sesame derives from Gullah ''benne'' which is akin to Malinke ''bĕne''. Use Culinary The seeds are eaten whole, made into a paste, ground into a powder, or pressed for a high-quality oil. The leaves can be eaten fresh or cooked and are used in Sub-Saharan Africa as a leaf vegetable. The leaves are mucilaginous ...

Heinrich Christian Friedrich Schumacher
Heinrich Christian Friedrich Schumacher (15 November 1757 in Glückstadt, Holstein – 9 December 1830) was a Denmark, Danish surgeon, botanist and professor of anatomy at the University of Copenhagen. Schumacher carried out significant research work in malacology, in other words on molluscs, and described several taxon, taxa. Life Early years (1757-1778) He was born to Joachim Christian Schumacher, a sergeant in the infantry of the Duchy of Schleswig, and his wife, Caroline Magdalene in Glückstadt in present-day Germany. In spite of his family's limited means, he received a good upbringing, and was sent to grammar school in Rendsburg. After confirmation became the apprentice of the regiment surgeon, Mehl, a learned and skilled man, who gave his eager student a thorough introduction to both medicine and botany, thereby waking Schumacher's natural gift for science. By 1773, at the age of 16, his keen efforts got him appointed as a military surgeon with his father's battalion in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antidote
An antidote is a substance that can counteract a form of poisoning. The term ultimately derives from the Greek term φάρμακον ἀντίδοτον ''(pharmakon antidoton)'', "(medicine) given as a remedy". An older term in English which is now rare is atterlothe, derived from " atter" ("poison" or "venom"). Antidotes for anticoagulants are sometimes referred to as reversal agents. The antidotes for some particular toxins are manufactured by injecting the toxin into an animal in small doses and extracting the resulting antibodies from the host animals' blood. This results in an antivenom that can be used to counteract venom produced by certain species of snakes, spiders, and other venomous animals. Some animal venoms, especially those produced by arthropods (such as certain spiders, scorpions, and bees) are only potentially lethal when they provoke allergic reactions and induce anaphylactic shock; as such, there is no "antidote" for these venoms; however anaphylactic shoc ...

Nezara Viridula
''Nezara viridula'', commonly known as the southern green stink bug (USA), southern green shield bug (UK) or green vegetable bug (Australia and New Zealand), is a plant-feeding stink bug. Believed to have originated in Ethiopia, it can now be found across the world.Squitier J.M. (1997, updated 2007) Southern green stink bug»Featured creatures, University of Florida Institute of Food and Agricultural services. Because of its preference for certain species of legumes, such as beans and soybeans, it is an economically important pest on such crops. Distribution ''Nezara viridula'' is a cosmopolitan species, living in tropical and subtropical regions of the Americas, Africa, Asia, Australasia, and Europe between 45 degrees north and 45 degrees south. Its exact origin is unknown, but it is believed to have originated from the Ethiopia region of East Africa, from where it has spread around the world due to its strong flight and human transport along trade routes.

Antigastra Catalaunalis
''Antigastra catalaunalis'' is a species of moth of the family Crambidae. The species was Species description, first described by Philogène Auguste Joseph Duponchel in 1833. It is Endemism, endemic to tropical and subtropical areas (South Asia, Malay Archipelago, Africa), but is also found in other areas due to its Lepidoptera migration, migratory nature. Description The wingspan is 19–22 mm. The forewings are pale yellow, veins and margins suffused with ferruginous, sometimes almost obscuring ground-colour; lines ferruginous, second strongly curved outwards on upper 2/3; small orbicular and discal spot fuscous; cilia whitish, base dark fuscous. Hindwings are yellow whitish, ferruginous-tinged, termen more ferruginous; a cloudy grey postmedian costal spot.

Sphingidae
The Sphingidae are a family of moths commonly called sphinx moths, also colloquially known as hawk moths, with many of their caterpillars known as hornworms. It includes about 1,450 species. It is best represented in the tropics, but species are found in every region.Scoble, Malcolm J. (1995): ''The Lepidoptera: Form, Function and Diversity'' (2nd edition). Oxford University Press & Natural History Museum London. They are moderate to large in size and are distinguished among moths for their agile and sustained flying ability, similar enough to that of hummingbirds as to be reliably mistaken for them. Their narrow wings and streamlined abdomens are adaptations for rapid flight. The family was named by French zoologist Pierre André Latreille in 1802. Some hawk moths, such as the hummingbird hawk-moth or the Hyles lineata, white-lined sphinx, hover in midair while they feed on nectar from flowers, so are sometimes mistaken for hummingbirds. This hovering capability is only known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cercospora Sesami
''Cercospora'' is a genus of ascomycete fungi. Most species have no known sexual stage, and when the sexual stage is identified, it is in the genus '' Mycosphaerella''. Most species of this genus cause plant diseases, and form leaf spots. It is a relatively well-studied genus of fungi, but there are countless species not yet described, and there is still much to learn about the best-known members of the genus. It has a cosmopolitan distribution worldwide. Selected species The GBIF accepts 837 species (as of July 2023); See also List of Cercospora species *'' Cercospora acetosella'' - found on sheep sorrel and other docks *'' Cercospora aciculina'' *'' Cercospora agerati'' *'' Cercospora alabemensis'' *'' Cercospora alismatis'' *'' Cercospora althaeina'' *'' Cercospora angreci'' - causes leaf spot of orchids *'' Cercospora angulata'' *'' Cercospora apii'' - causes leaf spot on celery, and found on other plants, including ''Impatiens'' * ''Cercospora apii'' f.sp.

Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), that is, square metres (), and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare (" hecto-" + "are") was thus 100 ''ares'' or km2 ( square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa () and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, is ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests.Manoel Cláudio da ...

Sprain
A sprain is a soft tissue injury of the ligaments within a joint, often caused by a sudden movement abruptly forcing the joint to exceed its functional range of motion. Ligaments are tough, inelastic fibers made of collagen that connect two or more bones to form a joint and are important for joint stability and proprioception, which is the body's sense of limb position and movement. Sprains may be mild (first degree), moderate (second degree), or severe (third degree), with the latter two classes involving some degree of tearing of the ligament. Sprains can occur at any joint but most commonly occur in the ankle, knee, or wrist. An equivalent injury to a muscle or tendon is known as a strain. The majority of sprains are mild, causing minor swelling and bruising that can be resolved with conservative treatment, typically summarized as RICE: rest, ice, compression, elevation. However, severe sprains involve complete tears, ruptures, or avulsion fractures, often leading to j ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scorpion
Scorpions are predatory arachnids of the Order (biology), order Scorpiones. They have eight legs and are easily recognized by a pair of Chela (organ), grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back Silurian, 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their Taxonomy (biology), taxonomy is being revised to account for 21st-century genomic studies. Scorpions primarily prey on insects and other invertebrates, but some species hunt vertebrates. They use their pincers to restrain and kill prey, or to prevent their own predation. The Scorpion sting, venomous sting is used for offense and defense. During courtship, the male and female ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
