Stem flow measurement on a silver birch. There are a variety of ways stemflow volume is measured in the field. The most common direct measurement currently used is the bonding of bisected PVC or other plastic tubing around the circumference of the tree trunk, connected and funneled into a graduated cylinder for manual or a tipping bucket rain gauge for automatic collection.
The word root ped-(usually in the combining forms peda-, pedi-, and pedo-) in English and various other Western languages has multiple Latin and Ancient Greek roots, and multiple meanings. Ped- (sometimes spelled paed- , pæd- , or rarely paid- , depending on the word and the language or dialect) is a root in English and many other Western ...
Tributaries, and the main stem river into which they flow, drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of 4,248 km (2,640 mi).
The protoxylem is thus closest to the center of the stem or root, and the metaxylem is closest to the periphery. The stems of seed plants typically have endarch development. [43] Mesarch is used when there is more than one strand of primary xylem in a stem or root, and the xylem develops from the middle of a strand in both directions. The ...
In linguistics, a word stem is a part of a word responsible for its lexical meaning. Typically, a stem remains unmodified during inflection with few exceptions due to apophony (for example in Polish, miast-o ("city") and w mieść-e ("in the city"); in English, sing, sang, and sung, where it can be modified according to morphological rules or peculiarities, such as sandhi).
Each headwater is considered one of the river's sources, as it is the place where surface runoffs from rainwater, meltwater, or spring water begin accumulating into a more substantial and consistent flow that becomes a first-order tributary of that river. The tributary with the longest course downstream of the headwaters is regarded as the main ...
The following is an alphabetical list of Greek and Latin roots, stems, and prefixes commonly used in the English language from A to G. See also the lists from H to O and from P to Z.
The idea of a vector flow, that is, the flow determined by a vector field, occurs in the areas of differential topology, Riemannian geometry and Lie groups. Specific examples of vector flows include the geodesic flow , the Hamiltonian flow , the Ricci flow , the mean curvature flow , and Anosov flows .
