The word slideshow does not appear in the "Webster’s New Twentieth Century Unabridged Dictionary" (1973 edition), but is accepted as correct spelling in Microsoft Word in both "Office 2000" and "Office XP" editions.
Slide
In photography, a slide is a thin translucent photograph bound in paper, plastic or similar frame and often used for projection with use of a slide projector for a slideshow. The terms reversal film and transparency are also used.
One can it from negative and print.
Slide (disambiguation)
Slide could be related to any of these.
Projection
Projection can be any of:
Slide projector
A slide projector is a device that is used to view photographic slides by using optical and mechanical
methods. It contains an electric light bulb. focusing lenses.
reflector and condensing lenses. a holder that holds the slide.
A flat piece of heat absorbing glass is often placed between the condensing lens and the slide, to avoid damaging the slide. This glass absorbs infrared. Light passes through the transparent slide and lens, and the resulting image is enlarged and projected onto a screen. So the audience can view its reflection.
The image may be projected onto a translucent "rear projection" screen. That is used for continuous automatic display for close viewing. This form of projection also avoids that people who look at the show interrupt the light stream or bump into the projector.
Slide projectors were common in the 1950s and 1960s as a form of entertainment; family members and friends would gather to view slideshows.
In-home photographic slides and slide projectors have largely been replaced by low cost paper prints, digital cameras, DVD media, video display monitors and digital projectors.
As of October 2004, "Kodak" no longer manufactures slide projectors. It is also increasingly difficult in some countries to locate photo processors who will process slide film. this is how to make an easy and cheap slide projector at home !! this can be also used for projects.
Video projector
A video projector takes a video signal and projects the corresponding image on a screen using a lens system. All video projectors use a very bright light to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings. Video projectors are widely used for conference room presentations, classroom training, and home theatre applications.
A video projector may also be built into a cabinet with a rear-projection screen to form a single unified display device, now popular for “home theater” applications.
Common display resolutions for a portable projector include SVGA (800×600 pixels), XGA (1024×768 pixels), and 720p (1280×720 pixels).
The cost of a device is not only determined by its resolution, but also by its light output, acoustic noise output, contrast, and other characteristics.
Peanut
A peanut is a plant in the legume family, "Fabaceae". It is native to South America, Central America and Mexico. Peanuts are annual herbaceous plants growing 30 to 50 cm (1 to 1.5 ft) tall.
The peanut plant flowers above ground, then develops its pods underground. Because of this, peanuts are often called groundnuts. Other names include goobers, pinders, arachides (French/Italian), and maní (Spanish). This strange legume yields shell-covered pods (fruits) that contain one or more seeds. A nut is a hard shelled fruit that comes from a plant whose fruit does not open to release its seed. A nut is a composite of the fruit and seed, some examples of true nuts are: acorns, beechnuts, chestnuts and hazelnuts.
So despite the name, the plant is not a nut in the biological sense, but a legume.
Peanuts grow by starting out as an above ground flower that, due to its heavy weight, bends towards the ground. The flower eventually burrows underground, which is where the peanut actually matures.
The veined brown shell or pod of the peanut contains two or three peanut kernels. Each oval-shaped kernel or seed is comprised of two off-white lobes that are covered by a brownish-red skin. Peanuts have a hardy, buttery and "nutty" taste.
Peanuts go by various names throughout the world with "goober" or "goober pea" being one of the most popular. Goober is derived from "nguba," the name for peanut in the Bantu language spoken in parts of Africa. Peanuts are known scientifically as Arachis hypogaea.
Peanuts are a favorite food, whether eaten alone as a snack food or mixed into candy, cookies, pies, and other bakery products. Peanut butter, made by grinding the roasted seeds, accounts for about one half the peanuts grown in the United States. Worldwide however, peanuts are grown chiefly to provide peanut oil. Farmers in Africa and Asia grow about 90 percent of the world's peanuts.
Peanuts have been cultivated in South America for a very long time. Today most peanuts are eaten roasted and salted. Peanut butter peanut brittle and candy bars are also often eaten. There are two kinds of peanut butter - chunky and creamy. Most American children prefer the chunky kind.
The U.S. introduced the peanut to the tropical South America, and India, China, West Africa, and itself to become the largest commercial producers of peanuts. The peanut was grown mainly for its edible oil, except in the U.S., where it was produced for grinding into peanut butter, for roasted, salted nuts; and for use in candy and bakery products. A small percentage of the U.S. crop is crushed for oil. In the southern U.S. the peanut is used extensively as feed for livestock.
Peanuts are a very good source of monounsaturated fats, the type of fat that is important in the heart-healthy Mediterranean diet. Studies of diets with a special emphasis on peanuts have shown that this little legume is a big ally for a healthy heart.
In addition to their monounsaturated fat content, peanuts feature an array of other nutrients that, in numerous studies, have been shown to promote heart health. Peanuts are good sources of vitamin E, niacin, folate, protein and manganese. In addition, peanuts provide resveratrol, the phenolic antioxidant also found in red grapes and red wine that is thought to be responsible for the French paradox: the fact that in France, people consume a diet that is not low in fat, but have a lower risk of cardiovascular disease compared to the U.S. Numerous research studies, including the Nurses' Health Study that involved over 86,000 women, have found that frequent nut consumption is related to reduced risk of cardiovascular disease.
Four types of peanuts are the most popular: Spanish, Runner, Virginia, and Valencia. There are also Tennessee Red and Tennessee White types. Certain types are preferred for particular uses because of differences in flavor, oil content, size, and shape. For many uses the different types are interchangeable. Most peanuts marketed in the shell are of the Virginia type, along with some Valencias selected for large size and the attractive appearance of the shell. Spanish peanuts are used mostly for peanut candy, salted nuts, and peanut butter. Most Runners are used to make peanut butter.
The various types are distinguished by branching habit and branch length. There are numerous varieties of each type of peanut.
Each year new varieties of peanuts are introduced somewhere in the peanut belt of the U.S. or in other countries. Introducing a new variety may mean change in the planting rate, adjusting the planter, harvester, dryer, cleaner, sheller, and method of marketing. There are two main growth forms: bunch and runner. Bunch types grow upright, while runner types grow near the ground.
Spanish Types
The small Spanish types are grown in South Africa, and in the southwestern and southeastern U.S. Prior to 1940, 90 percent of the peanuts grown in Georgia were Spanish types, but the trend since then has been larger seeded, higher yielding, more disease resistant varieties.
