A catena can form on various underlying or parent materials and in different climates. A mature catena is in equilibrium as the processes of deposition and erosion are in balance. catena translation in Latin-English dictionary. In addition, the top facets lose materials such as mineral salts when these are washed out by rain (eluviation), while the bottom facets gain materials when these are washed in (illuviation).[10][11]. [10] On impermeable acid rocks such as metamorphic schists in a high rainfall climate like that of Western Scotland, the catena consists of thick acidic peat forming wet bog on the flatter facets, and thinner, drier, somewhat less acidic peaty podsols on the steeper facets. Am. [1] Each soil type or "facet" differs somewhat from its neighbours, but all occur in the same climate and on the same underlying parent material. range noun. ): npl plural noun: Noun always used in plural form--for example, "jeans," "scissors.

[3], Lithology and relief can be the primary controls on the development of certain catenas[6] with easily disaggregated parent rock and high relief favoring particle redistribution and therefore the formation of distinct soils in particle-source and particle-deposition zones along a slope. The catena concept originated in Central Uganda, by chemist W.S. Catenation, chemical linkage into chains of atoms of the same element, occurring only among the atoms of an element that has a valence of at least two and that forms relatively strong bonds with itself. Catenas are found to be a great location for the study of soil science, given that the catena concept focuses on past history of the land surface, on hydrology, erosion, sediment transport, and pedogenic processes.

The result is a predictable sequence of soil facets. [10][11] On a permeable basic rock such as chalk, the catena may consist of thick brown earths on the flatter facets, with thin rendzinas on the steeper slopes, while the valley bottom may include alkaline fen peat or river alluvium. noun catenae, catenas. (from Latin catena, chain) an arrangement of two or more circular DNA molecules interlocked like links on a chain. Catena, v.a. There is nothing surprising in this: both names have the same origin or the same numbers of numerology. A catena in soil science (pedology) is a series of distinct but co-evolving soils arrayed down a slope. Collins Dictionary of Biology, 3rd ed. Find more Latin words at wordhippo.com! [7], Catenas can also develop on low relief hillslopes, but because less potential energy is available the redistribution of mass can be dominated by subsurface flow of plasma, a combination of dissolved and suspended solids in soil water. Die Idee der Synthese verzahnter Moleküle wird meist Richard Willstätter in einem Seminar in Zürich zwischen 1906 und 1912 zugeschrieben. Die Synthese von Catenanen gelang aber lange nur in geringen Ausbeuten und komplizierten Syntheseschritten, bis die Templatmethode mit Metallkomplexen von Jean-Pierre Sauvage von 1983[5] das Gebiet revolutionierte. The nomenclature used for these systems involves placing the number of components involved in square brackets prior to the name of the molecule. The concept of a catena was developed in order to analyze the regular variation of soils across a slope. They are conceptually related to other mechanically interlocked molecular … The catena concept originated in Central Uganda, by chemist W.S. Diese Ringe können nicht voneinander getrennt werden, ohne mindestens eine kovalente Ringbindung eines macrocyclischen Ringes zu brechen.

Catenate definition is - to connect in a series : link. Ab Anfang der 1990er Jahre synthetisierte er n-Catenane (mit n=2 bis 7 Ringen). Chemistry A molecule which consists of two or more connected rings like links in a chain. On a steeper slope in the middle of a catena, erosion, such as by runoff, is faster, so facets are typically thinner and drier. Allerdings ist diese Methode sehr ineffizient. [8][9][7], A catena forms when the climate, including precipitation and evaporation, is the same for the whole slope, and when sufficient time has passed for equilibrium to be reached between the processes that bring materials in to a facet and the processes that take materials away. Neben den Catenanen zählen Rotaxane und molekulare Knoten zur Gruppe der mechanisch verknüpften molekularen Architekturen.
