  2. Genetically modified maize - Wikipedia

    en.wikipedia.org/wiki/Genetically_modified_maize

    In 2009 the government of Mexico created a regulatory pathway for genetically modified maize, [85] but because Mexico is the center of diversity for maize, gene flow could affect a large fraction of the world's maize strains. [86] [87] A 2001 report in Nature presented evidence that Bt maize was cross-breeding with unmodified maize in Mexico. [88]

    MON 802 is an Insect Resistant maize under license from Monsanto Company. [2] Corn line MON802 was developed through genetic modification to be tolerant [3] to glyphosate herbicide and protect the plant from the European corn borer (Ostrinia nubilalis) (the Bt trait).

  4. Genetically modified crops - Wikipedia

    Non-target organisms were unaffected, except for lower populations some parasitoid wasps due to decreased populations of their pest host European corn borer; European corn borer is a target of Lepidoptera active Bt maize. Biogeochemical parameters such as lignin content did not vary, while biomass decomposition was higher.

    The paper concluded that rats fed the modified maize had severe health problems, including liver and kidney damage and large tumors. [239] The study provoked widespread criticism. Séralini held a press conference just before the paper was released in which he announced the release of a book and a movie. [240]

  6. Bt cotton - Wikipedia

    In 2013, a second issue being seen across the world, was the development of Bt resistant pests limiting the usefulness of Bt crops. [ 15 ] Main drivers for the widespread resistance in India and China included the high proportion of Bt cotton being planted, 90% and 95% respectively in 2011, [ 9 ] [ 16 ] and few refuge areas.

  7. La Géométrie - Wikipedia

    Book I is titled Problems Which Can Be Constructed by Means of Circles and Straight Lines Only. In this book he introduces algebraic notation that is still in use today. The letters at the end of the alphabet, viz., x, y, z, etc. are to denote unknown variables, while those at the start of the alphabet, a, b, c, etc. denote constants.

  8. Foundations of geometry - Wikipedia

    en.wikipedia.org/wiki/Foundations_of_geometry

    Euclidean geometry is a mathematical system attributed to the Alexandrian Greek mathematician Euclid, which he described (although non-rigorously by modern standards) in his textbook on geometry: the Elements. Euclid's method consists in assuming a small set of intuitively appealing axioms, and deducing many other propositions from these.

    The protein from maize is further enhanced by protein contributions from beans and pumpkin seeds, while pumpkin flesh provides large amounts of vitamin A; with the Three Sisters, farmers harvest about the same amount of energy as from maize monoculture, but get more protein yield from the inter-planted bean and pumpkin.
