Iyasile Naa
The ''Iyasile Naa'', also known as ''The legacy'', is a digital painting created by Ade Olufeko, a designer known for his multidisciplinary work on African social economics. The original artwork was created in 2013. It underwent enhancements in Lagos and was reissued in 2017 as a major collaboration project piece through an African conference at Oxford University. According to the ''Vanguard'' news, parts of the artwork were influenced by 1985's ''We Are the World'' music project. Legal experts suggest that the eventual buyer of the artwork's reissue cannot financially exploit the work until the year 2033, stating that all "proceeds at any time from sales will remain within the African economic system." Background In the spring of 2013, Olufeko known for his cross-disciplinary signature through technology, created the artwork on the premise of social inclusion, brain gain and innovation. The art piece originally titled, ''Whatever is destroyed is created again'', was made for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reverse Brain Drain
Reverse brain drain is a form of brain drain where human capital moves in reverse from a more developed country to a less developed country that is developing rapidly. These migrants may accumulate savings, also known as remittances, and develop skills overseas that can be used in their home country. Brain drain can occur when scientists, engineers, or other intellectual elites migrate to a more developed country to learn in its universities, perform research, or gain working experience in areas where education and employment opportunities are limited in their home country. These professionals then return to their home country after several years of experience to start a related business, teach in a university, or work for a multi-national in their home country. Their return is this "Reverse Brain Drain". The occurrence of reverse brain drain mostly depends on the state of the country's development, and also strategies and planning over a long period of time to reverse the migrat ...

Confetti
Confetti are small pieces or streamers of paper, mylar, or metallic material which are usually thrown at celebrations, especially parades and weddings. The origins are from the Latin ''confectum'', with ''confetti'' the plural of 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 1mm) and is universally shiny. Most table confetti are also shiny. While they are called metallic confetti they are actually metallized PVC. The most popular shape is the star. Seasonally, Snowflake Confetti are the most ...

Amethyst
Amethyst is a violet variety of quartz. The name comes from the Koine Greek αμέθυστος ''amethystos'' from α- ''a-'', "not" and μεθύσκω (Ancient Greek) / μεθώ (Modern Greek), "intoxicate", a reference to the belief that the stone protected its owner from drunkenness. Ancient Greeks wore amethyst and carved drinking vessels from it in the belief that it would prevent intoxication. Amethyst, a semiprecious stone, is often used in jewelry and is the traditional birthstone for February. Structure Amethyst is a purple variety of quartz (SiO2) and owes its violet color to irradiation, impurities of iron and in some cases other transition metals, and the presence of other trace elements, which result in complex crystal lattice substitutions.Michael O'Donoghue (2006), ''Gems'', Butterworth-Heinemann, 6th ed. The hardness of the mineral is the same as quartz, thus making it suitable for use in jewelry. Hue and tone Amethyst occurs in primary hues from a li ...

Coated Paper
Coated paper (also known as enamel paper, gloss paper, and thin paper) is paper that has been coated by a mixture of materials or a polymer to impart certain qualities to the paper, including weight, surface gloss, smoothness, or reduced ink absorbency. Various materials, including kaolinite, calcium carbonate, bentonite, and talc, can be used to coat paper for high-quality printing used in the packaging industry and in magazines. The chalk or china clay is bound to the paper with synthetic s, such as styrene-butadiene latexes and natural organic binders such as starch. The coating formulation may also contain chemical additives as dispersants, resins, or polyethylene to give water resistance and wet strength to the paper, or to protect against ultraviolet radiation. Varieties Machine-finished coated paper ''Machine-finished coated paper'' (MFC) has a basis weight of 48–80 g/m2. They have good surface properties, high print gloss and adequate sheet stiffness.

IMac
iMac is a family of all-in-one Mac desktop computers designed and built by Apple Inc. It has been the primary part of Apple's consumer desktop offerings since its debut in August 1998, and has evolved through seven distinct forms. In its original form, the iMac G3 had a gumdrop or egg-shaped look, with a CRT monitor, mainly enclosed by a colored, translucent plastic case, which was refreshed early on with a sleeker design notable for its slot-loaded optical drive. The second major revision, the iMac G4, moved the design to a hemispherical base containing all the main components and an LCD monitor on a freely moving arm attached to it. The third and fourth major revisions, the iMac G5 and the Intel iMac respectively, placed all the components immediately behind the display, creating a slim unified design that tilts only up and down on a simple metal base. The fifth major revision (mid-2007) shared the same form as the previous model, but was thinner and used anodized a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphics Tablet
A graphics tablet (also known as a digitizer, digital graphic tablet, pen tablet, drawing tablet, external drawing pad or digital art board) is a computer input device that enables a user to hand-draw images, animations and graphics, with a special pen-like stylus (computing), stylus, similar to the way a person draws images with a pencil and paper. These tablets may also be used to capture data or handwritten signatures. It can also be used to trace an image from a piece of paper that is taped or otherwise secured to the tablet surface. Capturing data in this way, by tracing or entering the corners of linear Polygonal chain, polylines or shapes, is called digitizing. The device consists of a rough surface upon which the user may "draw" or trace an image using the attached stylus (computing), stylus, a pen-like drawing apparatus. The image is shown on the computer computer display, monitor, though some graphic tablets now also incorporate an LCD screen for more realistic or natu ...

Mixed Media
In visual art, mixed media describes artwork in which more than one medium or material has been employed. Assemblages, collages, and sculpture are three common examples of art using different media. Materials used to create mixed media art include, but are not limited to, paint, cloth, paper, wood and found objects. Mixed media art is distinguished from multimedia art which combines visual art with non-visual elements, such as recorded sound, literature, drama, dance, motion graphics, music, or interactivity. History of mixed media The first modern artwork to be considered mixed media is Pablo Picasso's 1912 collage ''Still Life with Chair Caning'', which used paper, cloth, paint and rope to create a pseudo-3D effect. The influence of movements like Cubism and Dada contributed to the mixed media's growth in popularity throughout the 20th century with artists like Henri Matisse, Joseph Cornell, Jean Dubuffet, and Ellsworth Kelly adopting it. This led to further innovations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albedo
Albedo (; ) is the measure of the diffuse reflection of sunlight, solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black body that absorbs all incident radiation, to 1, corresponding to a body that reflects all incident radiation. Surface albedo is defined as the ratio of Radiosity (radiometry), radiosity ''J''e to the irradiance ''E''e (flux per unit area) received by a surface. The proportion reflected is not only determined by properties of the surface itself, but also by the spectral and angular distribution of solar radiation reaching the Earth's surface. These factors vary with atmospheric composition, geographic location, and time (see position of the Sun). While bi-hemispherical reflectance is calculated for a single angle of incidence (i.e., for a given position of the Sun), albedo is the directional integration of reflectance over all solar angles in a given period. The temporal resolution may range from seconds (as ob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Visual Perception
Visual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment. This is different from visual acuity, which refers to how clearly a person sees (for example "20/20 vision"). A person can have problems with visual perceptual processing even if they have 20/20 vision. The resulting perception is also known as vision, sight, or eyesight (adjectives ''visual'', ''optical'', and ''ocular'', respectively). The various physiological components involved in vision are referred to collectively as the visual system, and are the focus of much research in linguistics, psychology, cognitive science, neuroscience, and molecular biology, collectively referred to as vision science. Visual system In humans and a number of other mammals, light enters the eye through the cornea and is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auction
An auction is usually a process of buying and selling goods or services by offering them up for bids, taking bids, and then selling the item to the highest bidder or buying the item from the lowest bidder. Some exceptions to this definition exist and are described in the section about different types. The branch of economic theory dealing with auction types and participants' behavior in auctions is called auction theory. The open ascending price auction is arguably the most common form of auction and has been used throughout history. Participants bid openly against one another, with each subsequent bid being higher than the previous bid. An auctioneer may announce prices, while bidders submit bids vocally or electronically. Auctions are applied for trade in diverse contexts. These contexts include antiques, paintings, rare collectibles, expensive wines, commodities, livestock, radio spectrum, used cars, real estate, online advertising, vacation packages, emission trading, a ...

Patronage
Patronage is the support, encouragement, privilege, or financial aid that an organization or individual bestows on another. In the history of art, arts patronage refers to the support that kings, popes, and the wealthy have provided to artists such as musicians, painters, and sculptors. It can also refer to the right of bestowing offices or Benefice, church benefices, the business given to a store by a regular customer, and the patron saint, guardianship of saints. The word "patron" derives from the la, patronus ("patron"), one who gives benefits to his clients (see Patronage in ancient Rome). In some countries the term is used to describe political patronage or patronal politics, which is the use of state resources to reward individuals for their electoral support. Some patronage systems are legal, as in the Canadian tradition of the Prime Minister to appoint Senate of Canada, senators and the heads of a number of commissions and agencies; in many cases, these appointments go to ...
