microrelief

[′mī·krō·ri‚lēf]
(geography)
Irregularities of the land surface causing variations in elevation amounting to no more than a few feet.

Microrelief

 

relief forms that are details of larger surface forms, for example, knolls, channel banks and spits, small sinkholes, polygonal ground, sand ripples, and steppe hollows. Microrelief is usually produced by exogenous processes.

Surface roughness is directly related to the microrelief forms inherent to the material, or those caused by the treatment, and is of extreme clinical relevance, as rough surfaces tend to harbor bacteria, promote pigment absorption and increase surface deterioration.
Therefore, the hypotheses of this study are: a) the understory community is influenced by microrelief and show distinct structure, composition and diversity on different slope classes and b) the spatial distributions of plant species are related to particular topographic features.
(i) The fracture surface in V-notched specimens is characterized by the presence of brittle structural elements, such as cleavage facets, terraces, and individual regions with quasi-ductile microrelief, and by zones of local microdeformation (Figure 6(d)).
The use of the median is suggested by Persson (2005a) as a way to overcome the deviations caused by the shading of the microrelief formed on the surfaces of the soil samples.
The following parameters are determined: elevation above sea level, type of relief, exposure, slope in degrees, position on the slope (relative elevation) and microrelief.
The microrelief of the implant titanium nickelide thread surface has been established to be characterized by sharply marked roughness and nanostructuring, as well as by the presence of multiple macro- and micropores of irregular shape and different size, and some of them are of size below 100 nm (Figure 1 a).
The spatial contours of SP-1 shifted to a reduced portion of the microrelief due to the concentration of its vegetating members in a more favorable microsite (see Fig.
One of these methods is the formation of regularly spaced sinusoidal micro grooves on friction surfaces that are called "surfaces with a partially regular microrelief" according to GOST 24773-81 (Schneider 1982; Shaikhutdinov 2010).
The microrelief meadow is varied, but generally finds an arrangement in longitudinal strips, beam near riverbeds (the highest), meadow strip median and low terraces located to the edge.
In addition the role of microrelief heterogeneities has been also stressed as an essential source of variability in soil properties under rice cultivation [20, 37].
In the case of Vertisols, the presence of smectites is responsible for their unique morphological properties, such as the clay content (>30%), shrink-swell activities, presence of slickensides, wedge-shaped peds, and gilgai microrelief.
The new switch effect we have developed cannot be replicated using optical technologies for microrelief formation.
