Thlaspi Arvense
''Thlaspi arvense'', known by the common name field pennycress, is a flowering plant in the cabbage family Brassicaceae. It is native to Eurasia, and is a common weed throughout much of North America and its home. Description ''Thlaspi arvense'' is a foetid, hairless annual plant, growing up to tall, with upright branches. The stem leaves are arrow-shaped, narrow and toothed. It blooms between May and July, with racemes or spikes of small white flowers that have 4 sepals and 4 longer petals. Later it has round, flat, winged pods with a deep apical notch, measuring across. They contain small brown-black seeds. The common name 'pennycress' is derived from the shape of the seeds looking like an old English penny. Other English common names are: stinkweed, bastard cress, fanweed, field pennycress, frenchweed and mithridate mustard. Pennycress is an annual, overwintering herb with an unpleasant odor when its leaves are squeezed. It grows up to 40 to 80 cm depending on environmental ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tian Shan
The Tian Shan, also known as the Tengri Tagh or Tengir-Too, meaning the "Mountains of God/Heaven", is a large system of mountain ranges in Central Asia. The highest peak is Jengish Chokusu at high and located in Kyrgyzstan. Its lowest point is at the Turpan Depression, which is below sea level. The Tian Shan is sacred in Tengrism. Its second-highest peak is known as Khan Tengri, which can be translated as "Lord of the Spirits". At the 2013 Conference on World Heritage, the eastern portion of Tian Shan in western China's Xinjiang Region was listed as a World Heritage Site. The western portion in Kyrgyzstan, Kazakhstan, and Uzbekistan was then listed in 2016. Geography Tian Shan with the ancient Silk Road The Tian Shan range is located north and west of the Taklamakan Desert and directly north of the Tarim Basin. It straddles the border regions of Kazakhstan, Kyrgyzstan, Uzbekistan and Xinjiang in Northwest China. To the south, it connects with the Pamir Mountains ...

Parboiled
Parboiling (or leaching) is the partial or semi boiling of food as the first step in cooking. The word is from the Old French ''parbouillir'', 'to boil thoroughly' but by mistaken association with "part", it has acquired this definition. The word is often used when referring to parboiled rice. Parboiling can also be used for removing poisonous or foul-tasting substances from foods, and to soften vegetables before roasting them. Basic technique The food items are added to boiling water and cooked until they start to soften, then removed before they are fully cooked. Parboiling is usually used to partially cook an item which will then be cooked another way such as braising, grilling, or stir-frying. Parboiling differs from Blanching (cooking), blanching in that one does not cool the items using cold water or ice after removing them from the boiling water. Parboiled rice Sometimes raw rice or paddy is dehusked by using steam. This steam also partially boils the rice while ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glucosinolates
Glucosinolates are natural components of many pungent plants such as mustard, cabbage, and horseradish. The pungency of those plants is due to mustard oils produced from glucosinolates when the plant material is chewed, cut, or otherwise damaged. These natural chemicals most likely contribute to plant defence against pests and diseases, and impart a characteristic bitter flavor property to cruciferous vegetables. Occurrence Glucosinolates occur as secondary metabolites of almost all plants of the order Brassicales. This includes the economically important family Brassicaceae as well as Capparaceae and Caricaceae. Outside of the Brassicales, the genera '' Drypetes'' and '' Putranjiva'' in the family Putranjivaceae, are the only other known occurrence of glucosinolates. Glucosinolates occur in various edible plants such as cabbage (white cabbage, Chinese cabbage, broccoli), Brussels sprouts, watercress, arugula, horseradish, capers, and radishes where the breakdo ...

Erucic Acid
Erucic acid is a monounsaturated omega-9 fatty acid, denoted 22:1ω9. It has the chemical formula: . It is prevalent in wallflower seed and other plants in the family Brassicaceae, with a reported content of 20 to 54% in high erucic acid rapeseed oil and 42% in mustard oil. Erucic acid is also known as ''cis''-13-docosenoic acid and the trans isomer is known as brassidic acid. Cetoleic acid is a positional isomer of erucic acid. Uses Erucic acid is a precursor to brassylic acid, a C13-dicarboxylic acid that is used to make specialty polyamides and polyesters. The conversion entails ozonolysis, which selectively cleaves the C=C bond in erucic acid: CH3(CH2)7CH\dCH(CH2)11CO2H + O3 + 0.5 O2 -> CH3(CH2)7CO2H + HO2C(CH2)11CO2H Amides of erucic acid are used as lubricants and surfactants. Hydrogenation of erucic acid gives behenyl alcohol, , a pour point depressant (enabling liquids to flow at a lower temperature), and silver behenate, for use in photography. Sour ...

Water Use Efficiency
Water-use efficiency (WUE) refers to the ratio of plant biomass to water lost by transpiration, can be defined either at the leaf, at the whole plant or a population/stand/field level: *leaf level : photosynthetic water-use efficiency (also called instantaneous water-use efficiency WUEinst), which is defined as the ratio of the rate of net CO2 carbon assimilation (photosynthesis) to the rate of transpiration or stomatal conductance, then called intrinsic water-use efficiency (iWUE or Wi) *plant level : water-use efficiency of productivity (also called integrated water-use efficiency or transpiration efficiency,TE), which is typically defined as the ratio of dry biomass produced to the rate of transpiration. * field level : based on measurements of CO2 and water fluxes over a field of a crop or a forest, using the eddy covariance technique Research to improve the water-use efficiency of crop plants has been ongoing from the early 20th century, however with difficulties to actua ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hazara Region
Hazara (Hindko: هزاره; Urdu: ), historically known as Pakhli, is a region in northern Pakistan, falling administratively within the Hazara Division of the Khyber Pakhtunkhwa province. It forms the northernmost portion of Sindh Sagar Doab, and is mainly populated by the indigenous Hindko-speaking Hindkowans and Kohistani people, with a significant Pashto-speaking population. The inhabitants of Hazara are collectively called the Hazarewal.
