Georges Ville
Georges Ville (23 March 1824 – 22 February 1897) was a French agronomist and plant physiologist born in Pont-Saint-Esprit. In 1843 he started his career as an interne in pharmacy. From 1857 to 1897 he held the chair of ''Physique végétale'' at the Muséum national d'histoire naturelle in Paris. He is known for his research involving the absorption of nitrogen by plants. In 1849-1852 he carried out experiments on nitrogen absorption from the air by plants that reasserted 18th century theories espoused by Joseph Priestley and Jan Ingenhousz, stating that plants were capable of absorbing free nitrogen, a claim that was later opposed by Nicolas-Théodore de Saussure in 1804 and backed up by the experiments of Jean Senebier (1742-1809). The subject garnered enough interest in the scientific community that the French Academy of Sciences formed a committee to investigate Ville's work, resulting in a confirmation of his experiments on the matter. He performed extensive pioneer studi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jean Senebier
Jean Senebier (25 May 1742 – 22 July 1809) was a Republic and Canton of Geneva#History, Genevan Calvinist pastor and naturalist. He was chief librarian of the Republic of Geneva. A pioneer in the field of photosynthesis research, he provided extensive evidence that plants consume carbon dioxide and produced oxygen. He also showed a link between the amount of carbon dioxide available and the amount of oxygen produced and determined that photosynthesis took place at the parenchyma, the green fleshy part of the leaf. Biography Senebier was born in Geneva, the son of a wealthy merchant. He wrote extensively on plant physiology and was one of the major early pioneers of photosynthesis research. Senebier also published on the experimental method, first in 1775, and then in an expanded work, in 1802. His precise definition of the experimental method anticipated the work of noted French physiologist Claude Bernard fifty years later. Senebier also served as chief librarian of the R ...

People From Pont-Saint-Esprit
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ammonia
Ammonia is an inorganic chemical compound of nitrogen and hydrogen with the chemical formula, formula . A Binary compounds of hydrogen, stable binary hydride and the simplest pnictogen hydride, ammonia is a colourless gas with a distinctive pungent smell. It is widely used in fertilizers, refrigerants, explosives, cleaning agents, and is a precursor for numeous chemicals. Biologically, it is a common nitrogenous waste, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to fertilisers. Around 70% of ammonia produced industrially is used to make fertilisers in various forms and composition, such as urea and diammonium phosphate. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many chemicals. In many countries, it is classified as an List of extremely hazardous substances, extremely hazardous substance. Ammonia is toxic, cau ...

Stanislas-Étienne Meunier
Stanislas-Étienne Meunier (18 July 1843 – 29 April 1925) was a French geologist born in Paris. In 1864 he began work as an "assistant naturalist" to geologist Gabriel Auguste Daubrée (1814–1896), who was an important and lasting influence to Meunier's career. In 1867 he became affiliated with the Muséum national d'histoire naturelle, where from 1892 to 1920 he served as chair of geology. Meunier is remembered for his work in comparative and experimental geology, and is credited for introducing experimental geology into the classroom as a specific branch of physical science. In his studies of meteorites, he identified thirty chemical elements that could also be found in Earth-based rocks. Referring to research of Gustav Kirchhoff (1824–1887) and Robert Wilhelm Bunsen (1811–1899) involving spectral analysis of the Sun, he stated that a unity of chemical composition existed in the Solar System.

Vincennes
Vincennes (; ) is a commune in the Val-de-Marne department in the eastern suburbs of Paris, France. It is located from the centre of Paris. Vincennes is famous for its castle: the Château de Vincennes. It is next to but does not include the Bois de Vincennes, from which it took its name, which is attached to the city of Paris. History The Marquis de Sade was imprisoned in Vincennes fortress in 1777, where he remained until February 1784 although he escaped for a little over a month in 1778. Thereafter Vincennes fortress was closed and de Sade transferred to the Bastille. In 1821, the noted French poet, Alfred de Vigny, wrote his poem, "La Prison," which details the last days of the Man in the Iron Mask at Vincennes. The ministers of Charles X were imprisoned at the fortress of Vincennes after the July Revolution. A test was conducted in 1849 on Claude-Étienne Minié's invention the Minié ball which would prove successful and years later be adopted by the French ar ...

Chemical Fertilizers
A fertilizer or fertiliser is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment, or hand-tool methods. Historically, fertilization came from natural or organic sources: compost, animal manure, human manure, harvested minerals, crop rotations, and byproducts of human-nature industries (e.g. fish processing waste, or bloodmeal from animal slaughter). However, starting in the 19th century, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Academy Of Sciences
The French Academy of Sciences (, ) is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the academy), it is one of the five Academies of the . __TOC__ History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationale, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the academy's existence were relatively informal, since no statutes had as yet been laid down for the ins ...
