Narbonne
Narbonne ( , , ; ; ; Late Latin:) is a commune in Southern France in the Occitanie region. It lies from Paris in the Aude department, of which it is a sub-prefecture. It is located about from the shores of the Mediterranean Sea and was historically a prosperous port. From the 14th century it declined following a change in the course of the river Aude. While it is the largest commune in Aude, the capital of the Aude department is the smaller commune of Carcassonne. Etymology The source of the town's original name of Narbo is lost in antiquity, and it may have referred to a hillfort from the Iron Age close to the location of the current settlement or its occupants. The earliest known record of the area comes from the Greek Hecataeus of Miletus in the fifth century BC, who identified it as a Celtic harbor and marketplace at that time, and called its inhabitants the ''Ναρβαῖοι''. In ancient inscriptions the name is sometimes rendered in Latin and sometimes transl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polypeptides
Peptides are short chains of amino acids linked by peptide bonds. A polypeptide is a longer, continuous, unbranched peptide chain. Polypeptides that have a molecular mass of 10,000 Da or more are called proteins. Chains of fewer than twenty amino acids are called oligopeptides, and include dipeptides, tripeptides, and tetrapeptides. Peptides fall under the broad chemical classes of biological polymers and oligomers, alongside nucleic acids, oligosaccharides, polysaccharides, and others. Proteins consist of one or more polypeptides arranged in a biologically functional way, often bound to ligands such as coenzymes and cofactors, to another protein or other macromolecule such as DNA or RNA, or to complex macromolecular assemblies. Amino acids that have been incorporated into peptides are termed residues. A water molecule is released during formation of each amide bond.. All peptides except cyclic peptides have an N-terminal (amine group) and C-terminal (carboxyl group) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Narbonne
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] |

Ordre Des Palmes Académiques
A suite, in Western classical music, is an ordered set of instrumental or orchestral/concert band pieces. It originated in the late 14th century as a pairing of dance tunes; and grew in scope so that by the early 17th century it comprised up to five dances, sometimes with a prelude. The separate movements were often thematically and tonally linked. The term can also be used to refer to similar forms in other musical traditions, such as the Turkish fasıl and the Arab nuubaat. In the Baroque era, the suite was an important musical form, also known as ''Suite de danses'', ''Ordre'' (the term favored by François Couperin), ''Partita'', or ''Ouverture'' (after the theatrical "overture" which often included a series of dances) as with the orchestral suites of Christoph Graupner, Telemann and J.S. Bach. During the 18th century, the suite fell out of favour as a cyclical form, giving way to the symphony, sonata and concerto. It was revived in the later 19th century, but in a d ...

Ordre National Du Mérite
The (; ) is a French order of merit with membership awarded by the President of the French Republic, founded on 3 December 1963 by President Charles de Gaulle. The reason for the order's establishment was twofold: to replace the large number of ministerial orders previously awarded by the ministries; and to create an award that can be awarded at a lower level than the Legion of Honour, which is generally reserved for French citizens. It comprises about 185,000 members; 306,000 members have been admitted or promoted in 50 years. History The comprises about 185,000 members; 306,000 members have been admitted or promoted in 50 years. Half of its recipients are required to be women. Defunct ministerial orders The replaced the following ministerial and colonial orders: Colonial orders * (Order of the Star of Anjouan, 1874) * (Order of Nishan-e-Anuar or Order of Light, 1887) * (Order of the Black Star, 1889) Special ministerial orders of merit * (Order of Societal Me ...

Legion Of Honour
The National Order of the Legion of Honour ( ), formerly the Imperial Order of the Legion of Honour (), is the highest and most prestigious French national order of merit, both military and Civil society, civil. Currently consisting of five classes, it was originally established in 1802 by Napoleon, Napoleon Bonaparte, and it has been retained (with occasional slight alterations) by all later French governments and regimes. The order's motto is ' ("Honour and Fatherland"); its Seat (legal entity), seat is the Palais de la Légion d'Honneur next to the Musée d'Orsay, on the left bank of the Seine in Paris. Since 1 February 2023, the Order's grand chancellor has been retired General François Lecointre, who succeeded fellow retired General Benoît Puga in office. The order is divided into five degrees of increasing distinction: ' (Knight), ' (Officer), ' (Commander (order), Commander), ' (Grand Officer) and ' (Grand Cross).

Amyloplast
Amyloplasts are a type of plastid, double-enveloped organelles in plant cells that are involved in various biological pathways. Amyloplasts are specifically a type of leucoplast, a subcategory for colorless, non-pigment-containing plastids. Amyloplasts are found in roots and storage tissues, and they store and synthesize starch for the plant through the polymerization of glucose. Starch synthesis relies on the transportation of carbon from the cytosol, the mechanism by which is currently under debate. Starch synthesis and storage also takes place in chloroplasts, a type of pigmented plastid involved in photosynthesis. Amyloplasts and chloroplasts are closely related, and amyloplasts can turn into chloroplasts; this is for instance observed when potato tubers are exposed to light and turn green. Role in gravity sensing Amyloplasts are thought to play a vital role in gravitropism. Statoliths, a specialized starch-accumulating amyloplast, are denser than cytoplasm The cytop ...

Geotropic
Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant in response to gravity pulling on it. It also occurs in fungi. Gravity can be either "artificial gravity" or natural gravity. It is a general feature of all higher and many lower plants as well as other organisms. Charles Darwin was one of the first to scientifically document that roots show ''positive gravitropism'' and stems show ''negative gravitropism''. That is, roots grow in the direction of gravitational pull (i.e., downward) and stems grow in the opposite direction (i.e., upwards). This behavior can be easily demonstrated with any potted plant. When laid onto its side, the growing parts of the stem begin to display negative gravitropism, growing (biologists say, turning; see tropism) upwards. Herbaceous (non-woody) stems are capable of a degree of actual bending, but most of the redirected movement occurs as a consequence of root or stem growth outside. The mechanism is bas ...
