Henna
Henna is a reddish dye prepared from the dried and powdered leaves of the henna tree. It has been used since at least the ancient Egyptian period as a hair and body dye, notably in the temporary body art of mehndi (or "henna tattoo") resulting from the staining of the skin using dyes from the henna plant. After henna stains reach their peak colour, they hold for a few days and then gradually wear off by way of exfoliation, typically within one to three weeks. Henna has been used in ancient Egypt, ancient Near East and the Indian subcontinent to dye skin, hair, and fingernails; as well as fabrics including silk, wool, and leather. Historically, henna was used in West Asia including the Arabian Peninsula and in Carthage, other parts of North Africa, West Africa, Central Africa, the Horn of Africa and the Indian subcontinent. The name ''henna'' is used in other skin and hair dyes, such as ''black henna'' and ''neutral henna'', neither of which is derived from the henna plant. ...

Mehndi
Mehndi () is a form of temporary skin decoration using a paste created with henna. In the West, mehndi is commonly known as henna tattoo, although it is not a permanent tattoo. Mehndi is a popular form of body art in South Asia and resembles similar traditions of henna as body art found in North Africa, East Africa and the Middle East. There are many different names for mehndi across the languages of South Asia. There are many different designs and forms of mehndi, often known as henna. For celebrations, women traditionally apply mehndi to their hands and feet, however some people, such as cancer sufferers and women with alopecia, may also decide to adorn their scalps. Rich brown is the most popular henna color, which is produced using a natural dye made from the Lawsonia inermis plant. But modern patterns now incorporate hues like white, red, black, and gold, enabling more individualized and varied artistic expressions. In South Asia, mehndi is applied on the body during ...

Lawsonia Inermis
''Lawsonia inermis'', also known as hina, the henna tree, the mignonette tree, and the Egyptian privet, is a flowering plant and one of the only two species of the genus ''Lawsonia'', with the other being '' Lawsonia odorata''. It is used as a traditional medicinal plant. The species is named after the Scottish physician Isaac Lawson, a good friend of Linnaeus. Description Henna is a tall shrub or small tree, standing . It is glabrous and multi-branched, with spine-tipped branchlets. The leaves grow opposite each other on the stem. They are glabrous, sub- sessile, elliptical, and lanceolate (long and wider in the middle; average dimensions are 1.5–5.0 cm x 0.5–2 cm or .6–2 in x 0.2–0.8 in), acuminate (tapering to a long point), and have depressed veins on the dorsal surface. Henna flowers have four sepals and a calyx tube, with spread lobes. Its petals are ovate, with white or red stamens found in pairs on the rim of the calyx tube. The ovary is ...

Lawsone
Lawsone (2-hydroxy-1,4-naphthoquinone), also known as hennotannic acid, is a red-orange dye present in the leaves of the henna plant ('' Lawsonia inermis''), for which it is named, as well as in the common walnut ('' Juglans regia'') and water hyacinth ('' Pontederia crassipes''). Humans have used henna extracts containing lawsone as hair and skin dyes for more than 5,000 years. Lawsone reacts chemically with the protein keratin in skin and hair via a Michael addition reaction, resulting in a strong permanent stain that lasts until the skin or hair is shed. Darker colored staining is due to more lawsone–keratin interactions occurring, which evidently break down as the concentration of lawsone decreases and the tattoo fades. Lawsone strongly absorbs UV light, and aqueous extracts can be effective sunless tanning agents and sunscreens. Lawsone is a 1,4-naphthoquinone derivative, an analog of hydroxyquinone containing one additional ring. Lawsone isolation from ''Lawsonia ine ...

Indian Subcontinent
The Indian subcontinent is a physiographic region of Asia below the Himalayas which projects into the Indian Ocean between the Bay of Bengal to the east and the Arabian Sea to the west. It is now divided between Bangladesh, India, and Pakistan. (subscription required) Although the terms "Indian subcontinent" and "South Asia" are often also used interchangeably to denote a wider region which includes, in addition, Bhutan, the Maldives, Nepal and Sri Lanka, the "Indian subcontinent" is more of a geophysical term, whereas "South Asia" is more geopolitical. "South Asia" frequently also includes Afghanistan, which is not considered part of the subcontinent even in extended usage.Jim Norwine & Alfonso González, ''The Third World: states of mind and being'', pages 209, Taylor & Francis, 1988, Quote: ""The term "South Asia" also signifies the Indian Subcontinent""Raj S.

Silk
Silk is a natural fiber, natural protein fiber, some forms of which can be weaving, woven into textiles. The protein fiber of silk is composed mainly of fibroin and is most commonly produced by certain insect larvae to form cocoon (silk), cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular Prism (optics), prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Harvested silk is produced by several insects; but, generally, only the silk of various moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing holometabolism, complete metamorphosis, but some insects, such as webspinners and Gr ...

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metabolic reactions, DNA replication, Cell signaling, responding to stimuli, providing Cytoskeleton, structure to cells and Fibrous protein, organisms, and Intracellular transport, transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the Nucleic acid sequence, nucleotide sequence of their genes, and which usually results in protein folding into a specific Protein structure, 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called pep ...

Mill (grinding)
A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically, mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind ( windmill) or water (watermill). In the modern era, they are usually powered by electricity. The grinding of solid materials occurs through mechanical forces that break up the structure by overcoming the interior bonding forces. After the grinding the state of the solid is changed: the grain size, the grain size disposition and the grain shape. Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material (e.g. mining ore). For instance rock crushing or grinding to produce uniform aggregate size for construc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roman Empire
The Roman Empire ruled the Mediterranean and much of Europe, Western Asia and North Africa. The Roman people, Romans conquered most of this during the Roman Republic, Republic, and it was ruled by emperors following Octavian's assumption of effective sole rule in 27 BC. The Western Roman Empire, western empire collapsed in 476 AD, but the Byzantine Empire, eastern empire lasted until the fall of Constantinople in 1453. By 100 BC, the city of Rome had expanded its rule from the Italian peninsula to most of the Mediterranean Sea, Mediterranean and beyond. However, it was severely destabilised by List of Roman civil wars and revolts, civil wars and political conflicts, which culminated in the Wars of Augustus, victory of Octavian over Mark Antony and Cleopatra at the Battle of Actium in 31 BC, and the subsequent conquest of the Ptolemaic Kingdom in Egypt. In 27 BC, the Roman Senate granted Octavian overarching military power () and the new title of ''Augustus (title), Augustus'' ...

Pliny The Elder
Gaius Plinius Secundus (AD 23/24 79), known in English as Pliny the Elder ( ), was a Roman Empire, Roman author, Natural history, naturalist, and naval and army commander of the early Roman Empire, and a friend of the Roman emperor, emperor Vespasian. He wrote the encyclopedic (''Natural History''), a comprehensive thirty-seven-volume work covering a vast array of topics on human knowledge and the natural world, which became an editorial model for encyclopedias. He spent most of his spare time studying, writing, and investigating natural and geographic phenomena in the field. Among Pliny's greatest works was the twenty-volume ''Bella Germaniae'' ("The History of the German Wars"), which is Lost literary work, no longer extant. ''Bella Germaniae'', which began where Aufidius Bassus' ''Libri Belli Germanici'' ("The War with the Germans") left off, was used as a source by other prominent Roman historians, including Plutarch, Tacitus, and Suetonius. Tacitus may have used ''Bella Ger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoenicia
Phoenicians were an Ancient Semitic-speaking peoples, ancient Semitic group of people who lived in the Phoenician city-states along a coastal strip in the Levant region of the eastern Mediterranean, primarily modern Lebanon and the Syria, Syrian coast. They developed a Maritime history, maritime civilization which expanded and contracted throughout history, with the core of their culture stretching from Arwad in modern Syria to Mount Carmel. The Phoenicians extended their cultural influence through trade and colonization throughout the Mediterranean, from Cyprus to the Iberian Peninsula, evidenced by thousands of Canaanite and Aramaic inscriptions, Phoenician inscriptions. The Phoenicians directly succeeded the Bronze Age Canaanites, continuing their cultural traditions after the decline of most major Mediterranean basin cultures in the Late Bronze Age collapse and into the Iron Age without interruption. They called themselves Canaanites and referred to their land as Canaan, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
