Confetti Decorati ArteZucchero
Confetti are small pieces or streamers of paper, BoPET, mylar or metallic material, usually thrown at celebrations, especially parades and weddings. The origins are from the Latin ''confectum'', with ''confetti'' the plural of Italian language, Italian ''confetto'', small sweet. Modern paper confetti trace back to symbolic rituals of tossing grains and sweets during special occasions, traditional for numerous cultures throughout history as an ancient custom dating back to pagan times, but adapted from sweets and grains to paper through the centuries. Confetti are manufactured in multiple colors, and commercially available confetti come in many different shapes. A distinction is made between confetti and glitter; glitter is smaller than confetti (pieces usually no larger than 1 mm) and is universally shiny. Most table confetti is also shiny. While they are called metallic confetti they are actually metallized Polyvinyl chloride, PVC. Most party supply stores carry paper and meta ...

Tumblewing
A tumblewing or "tumble wing" or "tumbling wing" is a glider or kite wing design which rotates about an axis transverse to the apparent wind, not necessarily horizontal. Tumble wings are frequently employed in wind turbines (such as the Savonius design), and are also used in some types of confetti. Tumble wings may be made of any material that supports some stiffness for form, such as paper, plastic, metal, composites or wood. Many leaves falling from trees become tumble wing gliders. Tumbling wings generate lift by alternately flying and stalling as the angle of incidence changes with the spinning motion (see magnus effect and flettner rotor). Its mode of flight is more akin to confetti than traditional fixed-wing aircraft; however, several model aircraft, such as flettner airplanes, have been built with tumbling wings for lift. Tumble wings are employed as the wing of kite systems, a type of rotary kite, and many such patents exist. Because it does not need ballast, the ...

Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it, with more than 150 Nobel Prize-winners being featured since its inception. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter (painter), Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large-format New York City newspaper was released on August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the United States Patent and Trademark Office, U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 devi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombyx Mori
''Bombyx mori'', commonly known as the domestic silk moth, is a moth species belonging to the family Bombycidae. It is the closest relative of '' Bombyx mandarina'', the wild silk moth. Silkworms are the larvae of silk moths. The silkworm is of particular economic value, being a primary producer of silk. The silkworm's preferred food are the leaves of white mulberry, though they may eat other species of mulberry, and even leaves of other plants like the Osage orange. Domestic silk moths are entirely dependent on humans for reproduction, as a result of millennia of selective breeding. Wild silk moths, which are other species of ''Bombyx'', are not as commercially viable in the production of silk. Sericulture, the practice of breeding silkworms for the production of raw silk, has existed for at least 5,000 years in China, whence it spread to India, Korea, Nepal, Japan, and then the West. The conventional process of sericulture kills the silkworm in the pupal stage. The domestic s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chalk
Chalk is a soft, white, porous, sedimentary carbonate rock. It is a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of microscopic plankton that had settled to the sea floor. Chalk is common throughout Western Europe, where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in places such as the Dover cliffs on the Kent coast of the English Channel. Chalk is mined for use in industry, such as for quicklime, bricks and builder's putty, and in agriculture, for raising pH in soils with high acidity. It is also used for " blackboard chalk" for writing and drawing on various types of surfaces, although these can also be manufactured from other carbonate-based minerals, or gypsum. Description Chalk is a fine-textured, earthy type of limestone distinguished by its light colour, softness, and high porosity. It is composed mostly of tiny fragments of the calcite shells or sk ...

Coriander
Coriander (), whose leaves are known as cilantro () in the U.S. and parts of Canada, and dhania in parts of South Asia and Africa, is an annual plant, annual herb (''Coriandrum sativum'') in the family Apiaceae. Most people perceive the leaves as having a fresh, slightly citrus taste. Due to variations in the gene OR6A2, some people perceive it to have a soap-like taste, or even a pungent or rotten taste. It is native to the Mediterranean Basin. All parts of the plant are edible, but the fresh leaves and the dried seeds are the parts most traditionally used in cooking. It is used in certain cuisines, like Mexican cuisine, Mexican, Indian cuisine, Indian and Southeast Asian cuisine, Southeast Asian. Description It is a soft plant growing to tall. The leaves are variable in shape, broadly lobed at the base of the plant, and slender and feathery higher on the flowering stems. The flowers are borne in small umbels, white or very pale pink, asymmetrical, with the petals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juan Fernández De Velasco Y Tovar, 5th Duke Of Frías
Juan Fernández de Velasco, 5th Duke of Frías ( – 15 March 1613) was a Spanish nobleman and diplomat. Biography Juan Fernández de Velasco was the son of Íñigo Fernández de Velasco; and of Maria Angela de Aragón y Guzmán El Bueno. He inherited his father's title of Constable of Castile, and was present at the signing of the Treaty of London (1604). Although he was not present for much of the negotiations, he was depicted in the '' Somerset House Conference'' group portrait now held at the National Portrait Gallery, London. London in 1604 He was sent to London to sign the recently negotiated peace treaty. The resident Spanish ambassador, the Count of Villamediana, asked King James if Velasco could be lodged at Somerset House, and Anne of Denmark granted his request. The lodging was decorated with royal tapestries, and his bedchamber furnished with a bed of "morado damask" bordered with gold. The furnishings were intended to be as rich as if the King of Spain, Philip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ivrea
Ivrea (; ; ; ) is a town and ''comune'' of the Metropolitan City of Turin in the Piedmont region of northwestern Italy. Situated on the road leading to the Aosta Valley (part of the medieval Via Francigena), it straddles the Dora Baltea and is regarded as the capital of the Canavese area. Founded by the Romans under the name "Eporedia," the town became the center of the March of Ivrea during the Middle Ages and briefly served as the capital of the Kingdom of Italy in the 11th century. It later became part of the possessions of the House of Savoy. In the 20th century, Ivrea gained international recognition as the headquarters of the Olivetti company, a pioneer in technological innovation, known for creating some of the first computers. Thanks to Olivetti, the town also became a center of architectural innovation, with the construction of several modernist buildings that reflected the era's progressive spirit. On July 1, 2018, the site which is known as "Industrial City of the 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries, similarly to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralised authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—once part of the Byzantine Empire� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venturi Effect
The Venturi effect is the reduction in fluid pressure that results when a moving fluid speeds up as it flows from one section of a pipe to a smaller section. The Venturi effect is named after its discoverer, the Italian physicist Giovanni Battista Venturi, and was first published in 1797. The effect has various engineering applications, as the reduction in pressure inside the constriction can be used both for measuring the fluid flow and for moving other fluids (e.g. in a vacuum ejector). Background In inviscid fluid dynamics, an incompressible fluid's velocity must ''increase'' as it passes through a constriction in accord with the principle of mass continuity, while its static pressure must ''decrease'' in accord with the principle of conservation of mechanical energy (Bernoulli's principle) or according to the Euler equations. Thus, any gain in kinetic energy a fluid may attain by its increased velocity through a constriction is balanced by a drop in pressure because ...
