In rangelands, pattern and processes below-ground are important for a complete understanding of their ecology. Recent studies in grass-dominated communities in Europe, North America and South America indicate that root ...

Aims: In arid communities, it has been proposed that individual plants can extend their roots beyond their canopy exploring neighbouring bare ground areas. This becomes relevant in systems where the vegetation is distributed ...

Supernumerary roots consist of a developmental disturbance which can occur to any teeth, and knowledge about its occurrence is particularly important for the conduction of surgical or endodontic treatment of the affected ...

Using digitized images of the three-dimensional, branching structures for root systems of bean seedlings, together with analytical and numerical methods that map a common susceptible-infected- recovered (`SIR`) epidemiological ...

Supernumerary roots consist of a developmental disturbance which can occur to any teeth, and knowledge about its occurrence is particularly important for the conduction of surgical or endodontic treatment of the affected ...

The objective of this study was to analyze the root distribution of grasses and shrubs, at different soil depths, in two ecological sites (ES): highland (forest) and lowland (grassland). The root density (RD) estimation ...

Objective: Root canal sealers can interact physically or chemically with dentine. The aim of this study was to characterize the dentine-root canal sealer interface of experimental sealers based on Portland cement using an ...

An asteroidal triple is a stable set of three vertices such that each pair is connected by a path avoiding the neighborhood of the third vertex. An asteroidal quadruple is a stable set of four vertices such that any three ...
