Is the zone of influence colonized by roots of neighboring species? Field tests in a Patagonian steppe
(Academic Press Ltd - Elsevier Science Ltd, 2017-02)
In general, there is more knowledge about aboveground structure and processes than about those belowground. It has been proposed that plants are belowground territorial and root segregation explains species coexistence. ...
In vitro evaluation of root canal preparation using oscillatory and rotary systems in flattened root canals
(Universidade de São Paulo (USP), Faculdade de Odontologia de Bauru, 2007-01-01)
Objective: the aim of this study was to evaluate the biomechanical preparation of flattened root canals using the following systems: Endo-Eze AET stainless steel oscillatory instruments (Ultradent) and RaCe rotary NiTi ...
Effects of rooting media, indolbutyric acid and fertilization on the rooting of rose (Rosa sp. 'Dalas') leafy cuttings
(1999-12-01)
The objectives of this study were to evaluate the effects of rooting media (vermiculite, carbonized rice bark, fenolic spume and sand), presence of IBA (indole-3-butyric acid) and presence of fertilization during the rooting ...
Effect of oxygen deficiency on nitrogen assimilation and amino acid metabolism of soybean root segments
(Springer WienWienAustria, 2013)
Resistance to compression of weakened roots subjected to different root reconstruction protocols
(Universidade de São Paulo (USP), Faculdade de Odontologia de Bauru, 2011-11-01)
Objective: This study evaluated, in vitro, the fracture resistance of human non-vital teeth restored with different reconstruction protocols. Material and methods: Forty human anterior roots of similar shape and dimensions ...

Histological evaluation of the response of apical tissues to glass ionomer and zinc oxide eugenol based sealers in dog teeth after root canal treatment
(Munksgaard Int Publ Ltd, 1998-12-01)
The object of the study was to compare two commercial root canal sealers: Ketac-Endo (a glass ionomer cement) and Fill Canal (a zinc oxide-eugenol cement). A total of 34 root canals from dog premolars with vital pulps were ...
Root volume and dry matter of peanut plants as a function of soil bulk density and soil water stress
(2008-04-01)
Soil compaction may be defined as the pressing of soil to make it denser. Soil compaction makes the soil denser, decreases permeability of gas and water exchange as well as alterations in thermal relations, and increases ...
Influence of the type of vehicle and limit of obturation on apical and periapical tissue response in dogs' teeth after root canal filling with mineral trioxide aggregate
(Elsevier B.V., 2007-06-01)
The purpose of this study was to investigate the influence of the type of vehicle (distilled water or propyleneglycol) on the response of apical tissues of dogs' teeth after root canal filling with mineral trioxide aggregate ...
Mineral trioxide aggregate repair of lateral root perforations
(2001-12-01)
This study was conducted to observe the healing process of intentional lateral root perforation repaired with mineral trioxide aggregate (MTA). Forty-eight root canals of dogs' teeth were instrumented and filled. After ...
