Canola Harvest
Close-up of canola blooms Canola flower Rapeseed oil is one of the oldest known vegetable oils. There are both edible and industrial forms produced from rapeseed, the seed of several cultivars of the plant family Brassicaceae. Historically, it was eaten in limited quantities due to high levels of erucic acid, which is damaging to the cardiac muscle of animals and imparts a bitter taste, and glucosinolates, which made it less nutritious in animal feed. Rapeseed oil can contain up to 54% erucic acid. Canola oil is a food-grade version derived from rapeseed cultivars bred for low erucic acid content. Also known as low erucic acid rapeseed (LEAR) oil, it has been generally recognized as safe by the United States Food and Drug Administration. Canola oil is limited by government regulation to a maximum of 2% erucic acid by weight in the US and the EU, with special regulations for infant food. These low levels of erucic acid do not cause harm in humans. In commerce, non-food variet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cabbage
Cabbage, comprising several cultivars of ''Brassica oleracea'', is a leafy green, red (purple), or white (pale green) biennial plant grown as an annual vegetable crop for its dense-leaved heads. It is descended from the wild cabbage ( ''B. oleracea'' var. ''oleracea''), and belongs to the "cole crops" or brassicas, meaning it is closely related to broccoli and cauliflower (var. ''botrytis''); Brussels sprouts (var. ''gemmifera''); and Savoy cabbage (var. ''sabauda''). A cabbage generally weighs between . Smooth-leafed, firm-headed green cabbages are the most common, with smooth-leafed purple cabbages and crinkle-leafed savoy cabbages of both colours being rarer. Under conditions of long sunny days, such as those found at high northern latitudes in summer, cabbages can grow quite large. , the heaviest cabbage was . Cabbage heads are generally picked during the first year of the plant's life cycle, but plants intended for seed are allowed to grow a second year and must be ...

Genetic Engineering
Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA is obtained by either isolating and copying the genetic material of interest using recombinant DNA methods or by artificially synthesising the DNA. A construct is usually created and used to insert this DNA into the host organism. The first recombinant DNA molecule was made by Paul Berg in 1972 by combining DNA from the monkey virus SV40 with the lambda virus. As well as inserting genes, the process can be used to remove, or "knock out", genes. The new DNA can be inserted randomly, or targeted to a specific part of the genome. An organism that is generated through genetic engineering is considered to be genetically modified (GM) an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baldur R
Baldr (also Balder, Baldur) is a god in Germanic mythology. In Norse mythology, Baldr (Old Norse: ) is a son of the god Odin and the goddess Frigg, and has numerous brothers, such as Thor and Váli. In wider Germanic mythology, the god was known in Old English as , and in Old High German as , all ultimately stemming from the Proto-Germanic theonym ('hero' or 'prince'). During the 12th century, Danish accounts by Saxo Grammaticus and other Danish Latin chroniclers recorded a euhemerized account of his story. Compiled in Iceland during the 13th century, but based on older Old Norse poetry, the ''Poetic Edda'' and the ''Prose Edda'' contain numerous references to the death of Baldr as both a great tragedy to the Æsir and a harbinger of Ragnarök. According to ''Gylfaginning'', a book of Snorri Sturluson's Prose Edda, Baldr's wife is Nanna and their son is Forseti. Baldr had the greatest ship ever built, Hringhorni, and there is no place more beautiful than his hall, Breidabli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keith Downey (agricultural Scientist)
Richard Keith Downey, (born January 26, 1927) is a Canadian agricultural scientist and, as one of the originators of canola, became known as the "Father of Canola". Born in Saskatoon, Saskatchewan, In 1951 he received a B.S.A. and in 1952 an M.Sc. from the University of Saskatchewan. He received his Ph.D. from Cornell University in 1961. In 1951 he started working for Agriculture Canada, becoming in 1993 a Senior Research Scientist Emeritus. In 1993, he started his own firm and is president of Canoglobe Consulting Inc. He worked with Baldur Stefansson to develop a variety of rapeseed that could be used as an edible oil. This is known as canola and is one of Canada’s top edible oils and one of the largest oilseed crops in the world. He is the breeder and co-breeder of 13 rapeseed/canola varieties and five condiment mustard varieties. In 1998, "Downey Street" at a research and development park in Saskatoon was named in his honour. Honours * 1963 Bond Gold Medal, American Oil C ...

Chlorophyll
Chlorophyll (also chlorophyl) is any of several related green pigments found in cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words , ("pale green") and , ("leaf"). Chlorophyll allow plants to absorb energy from light. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum. Hence chlorophyll-containing tissues appear green because green light, diffusively reflected by structures like cell walls, is less absorbed. Two types of chlorophyll exist in the photosystems of green plants: chlorophyll ''a'' and ''b''. History Chlorophyll was first isolated and named by Joseph Bienaimé Caventou and Pierre Joseph Pelletier in 1817. The presence of magnesium in chlorophyll was discovered in 1906, and was that element's first detection in living tissue. After initial work done by German chemi ...

Oil Lamp
An oil lamp is a lamp used to produce light continuously for a period of time using an oil-based fuel source. The use of oil lamps began thousands of years ago and continues to this day, although their use is less common in modern times. They work in the same way as a candle but with fuel that is liquid at room temperature, so that a container for the oil is required. A textile wick drops down into the oil, and is lit at the end, burning the oil as it is drawn up the wick. Oil lamps are a form of lighting, and were used as an alternative to candles before the use of electric lights. Starting in 1780, the Argand lamp quickly replaced other oil lamps still in their basic ancient form. These in turn were replaced by the kerosene lamp in about 1850. In small towns and rural areas the latter continued in use well into the 20th century, until such areas were finally electrified and light bulbs could be used. Sources of fuel for oil lamps include a wide variety of plants such as n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
