In the processing of photographic films, plates or papers, the photographic developer (or just developer) is one or more chemicals that convert the latent image to a visible image. Developing agents achieve this conversion by reducing the silver halides, which are pale-colored, into silver metal, which is black (when a fine particle). The conversion occurs within the gelatine matrix. The special feature of photography is that the developer only acts on those particles of silver halides that have been exposed to light. Generally, the longer a developer is allowed to work, the darker the image.
For black-and-white photography, the developer typically consists of a mixture of chemical compounds prepared as an aqueous solution. Three main components of this mixture are:
Oracle Developer Suite is a suite of development tools released by the Oracle Corporation. The principal components were initially Oracle Forms and Oracle Reports, although the suite was later expanded to include JDeveloper amongst others.
In the early 1990s, Oracle had two complementary, but quite different tools - SQL*Forms and SQL*ReportWriter. Both were character-based and there was some integration between the two although they were sold as separate products. The developer interface became more similar over time and they were eventually grouped together as Oracle IDE (Integrated Development Environment).
The suite was renamed to Oracle Developer and then to Oracle Developer/2000.
As with most products that had 2000 in their name, this was dropped after 1999 and the suite was renamed Oracle Developer Suite. Tools such as JDeveloper and Oracle Designer were added over subsequent years.
Most of the component parts of Oracle Developer Suite are now part of what Oracle calls Oracle Fusion Middleware.
A rose (/ˈroʊz/) is a woody perennial flowering plant of the genus Rosa, in the family Rosaceae. There are over 100 species and thousands of cultivars. They form a group of plants that can be erect shrubs, climbing or trailing with stems that are often armed with sharp prickles. Flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwest Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses.
The name rose comes from French, itself from Latin rosa, which was perhaps borrowed from Oscan, from Greek ρόδον rhódon (Aeolic βρόδον wródon), itself borrowed from Old Persian wrd- (wurdi), related to Avestan varəδa, Sogdian ward, Parthian wâr.
Roses have been long used as symbols in a number of societies. Roses are ancient symbols of love and beauty. "Rose" means pink or red in a variety of languages (such as the Romance languages and Greek).
The rose was sacred to a number of goddesses including Isis, whose rose appears in the late classical allegorical novel The Golden Ass as "the sweet Rose of reason and virtue" that saves the hero from his bewitched life in the form of a donkey. The ancient Greeks and Romans identified the rose with the goddess of love, Aphrodite (Greek name) and Venus (Roman name).
In Rome a wild rose would be placed on the door of a room where secret or confidential matters were discussed. The phrase sub rosa, or "under the rose", means to keep a secret — derived from this ancient Roman practice.
The cultivation of geometrical gardens, in which the rose has often held pride of place, has a long history in Iran and surrounding lands. In the lyric ghazal, it is the beauty of the rose that provokes the longing song of the nightingale - an image prominent, for example, in the poems of Hafez.
A rosé (from French rosé; also known as rosado in Portugal and Spanish-speaking countries and rosato in Italy) is a type of wine that incorporates some of the color from the grape skins, but not enough to qualify it as a red wine. It may be the oldest known type of wine, as it is the most straightforward to make with the skin contact method. The pink color can range from a pale "onion"-skin orange to a vivid near-purple, depending on the varietals used and winemaking techniques. There are three major ways to produce rosé wine: skin contact, saignée and blending. Rosé wines can be made still, semi-sparkling or sparkling and with a wide range of sweetness levels from bone-dry Provençal rosé to sweet White Zinfandels and blushes. Rosé wines are made from a wide variety of grapes and can be found all around the globe.
When rosé wine is the primary product, it is produced with the skin contact method. Black-skinned grapes are crushed and the skins are allowed to remain in contact with the juice for a short period, typically one to three days. The must is then pressed, and the skins are discarded rather than left in contact throughout fermentation (as with red wine making). The longer that the skins are left in contact with the juice, the more intense the color of the final wine.
