Vitamin E
Vitamin E is a group of eight compounds related in molecular structure that includes four tocopherols and four tocotrienols. The tocopherols function as fat-soluble antioxidants which may help protect cell membranes from reactive oxygen species. Vitamin E is classified as an essential nutrient for humans. Various government organizations recommend that adults consume between 3 and 15 mg per day, while a 2016 worldwide review reported a median dietary intake of 6.2 mg per day. Sources rich in vitamin E include seeds, nuts, vegetable oil, seed oils, Peanut butter#Nutritional profile, peanut butter, food fortification, vitamin E–fortified foods, and dietary supplements. Symptomatic vitamin E deficiency is rare, usually caused by an underlying problem with digesting dietary fat rather than from a diet low in vitamin E. Deficiency can cause neurological disorders. Tocopherols and tocotrienols both occur in α (alpha), β (beta), γ (gamma), and δ (delta) forms, as dete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanist
Botany, also called plant science, is the branch of natural science and biology studying plants, especially Plant anatomy, their anatomy, Plant taxonomy, taxonomy, and Plant ecology, ecology. A botanist or plant scientist is a scientist who specialises in this field. "Plant" and "botany" may be defined more narrowly to include only land plants and their study, which is also known as phytology. Phytologists or botanists (in the strict sense) study approximately 410,000 species of Embryophyte, land plants, including some 391,000 species of vascular plants (of which approximately 369,000 are flowering plants) and approximately 20,000 bryophytes. Botany originated as history of herbalism#Prehistory, prehistoric herbalism to identify and later cultivate plants that were edible, poisonous, and medicinal, making it one of the first endeavours of human investigation. Medieval physic gardens, often attached to Monastery, monasteries, contained plants possibly having medicinal benefit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leopold Mannes
Leopold Damrosch Mannes (December 26, 1899 – August 11, 1964) was an American musician, who, together with Leopold Godowsky Jr., created the first practical color transparency film, Kodachrome. Life and career Mannes was born in New York City. He was a son of David Mannes and Clara (Damrosch) Mannes, and a brother of writer Marya Mannes. His parents founded the Mannes College of Music in New York. His maternal grandfather was conductor Leopold Damrosch, and his maternal uncles were conductors Walter Damrosch and Frank Damrosch. His father was Jewish; his mother was from a mostly Lutheran German family (and was of part Jewish descent through her own grandfather). Mannes and Godowsky's experimentation with color photography began in 1917, after seeing the film ''Our Navy'' in Prizma Color, which was advertised as a color film. Because of the low quality the boys felt cheated and decided to do something about it. They designed a movie camera and projector, each with three lens ...

Founded in 1850, it was the first newspaper to be published in Utah. The publication's name is from the geographic area of State of Deseret, Deseret identified by Utah's Mormon pioneers, pioneer settlers, and much of the publication's reporting is rooted in that region.

16 Mm Film
16 mm film is a historically popular and economical Film gauge, gauge of Photographic film, film. 16 mm refers to the width of the film (about inch); other common film gauges include 8 mm film, 8 mm and 35mm movie film, 35 mm. It is generally used for non-theatrical (e.g., industrial, educational, television) film-making, or for low-budget motion pictures. It also existed as a popular amateur or home movie-making format for several decades, alongside 8 mm film and later Super 8 film. Kodak, Eastman Kodak released the first 16 mm "outfit" in 1923, consisting of a Ciné-Kodak camera, Kodascope projector, tripod, screen and splicer, for US$335 (). RCA Records, RCA-Victor introduced a 16 mm sound movie projector in 1932, and developed an optical sound-on-film 16 mm camera, released in 1935.

Reversal Film
In photography, reversal film or slide film is a type of photographic film that produces a positive image on a transparent base. Instead of negatives and prints, reversal film is processed to produce transparencies or diapositives (abbreviated as "diafilm" or "dia" in some languages like German, Romanian or Hungarian). Reversal film is produced in various sizes, from 35 mm to roll film to 8×10 inch sheet film. A slide is a specially mounted individual transparency intended for projection onto a screen using a slide projector. This allows the photograph to be viewed by a large audience at once. The most common form is the 35 mm slide, with the image framed in a 2×2 inch cardboard or plastic mount. Some specialized labs produce photographic slides from digital camera images in formats such as JPEG, from computer-generated presentation graphics, and from a wide variety of physical source material such as fingerprints, microscopic sections, paper documents, astr ...

Subtractive Color
Subtractive color or subtractive color mixing predicts the spectral power distribution of light after it passes through successive layers of partially absorbing media. This idealized model is the essential principle of how dyes and pigments are used in color printing and photography, where the perception of color is elicited after white light passes through microscopic "stacks" of partially absorbing media, allowing some wavelengths of light to reach the eye and not others. It is also a concept seen in painting, wherein the colors are mixed or applied in successive layers. Process The subtractive color mixing model predicts the resultant spectral power distribution of light filtered through overlaid partially absorbing materials on a reflecting or transparent surface. Each layer partially absorbs some wavelengths of light from the illumination spectrum while letting others pass through, resulting in a colored appearance. The resultant spectral power distribution is predicted b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kodachrome
Kodachrome is the brand name for a color reversal film introduced by Eastman Kodak in 1935. It was one of the first successful color materials and was used for both cinematography and still photography. For many years, Kodachrome was widely used for professional color photography, especially for images intended for publication in print media. Because of its complex processing requirements, the film was initially sold only with the cost of processing; independent photography stores were prohibited from developing Kodachrome. To develop the film, customers had to mail it to Kodak, which would then send the developed film back as part of the purchase price. In 1954, the U.S. Department of Justice found that this practice violated antitrust laws by being uncompetitive. Kodak then entered into a consent decree, requiring the company to offer Kodachrome film for sale without the development fee, as well as license Kodachrome development patents to independent photography stores.
