Mechanical and biological approaches to alleviate soil compaction in tropical soils: assessed by root growth and activity (Rb uptake) of soybean and maize grown in rotation with cover crops
(Wiley-Blackwell, 2017-03-01)
Chiselling has been used to alleviate soil compaction but cover crops with deep, vigorous roots can improve root growth and activity of the cash crop for a longer time. The determination of root activity in addition to ...
Canal preparation and filling techniques do not influence the fracture resistance of extensively damaged teeth
(2014-01-01)
The purpose of this study was to assess the fracture resistance of extensively damaged teeth after two root canal preparation techniques (hand and rotary files) and after two filling techniques (active and passive compaction). ...
Differences between root traits of early- and late-successional trees influence below-ground competition and seedling establishment.
(Journal of Tropical Ecology, v. 32, n. 4, p. 300-313, Jul. 2016., 2016)
Root canal treatment of three-rooted maxillary second premolars: Report of four cases
(Wiley-Blackwell Publishing, Inc, 2009-08-01)
The aim of this report is to contribute to a better understanding of the radiographic, clinical and anatomic findings in maxillary second premolars. This paper reports the endodontic treatment of two cases of three-rooted ...
Variation in biomass allocation and root functional parameters in response to fire history in Brazilian savannas
(2021-01-01)
Fire is a fundamental ecological factor in savannas because it affects vegetation dynamics and ecosystem functioning. However, the effects of fire on below-ground compartments, including biomass and root traits, and their ...
Repair characteristics of horizontal root fracture: a case report
(Blackwell Munksgaard, 2002-04-01)
Radicular fractures in permanent teeth are uncommon injuries among dental traumas, comprising 0.5-7% of the cases. Fracture occurs most often in the middle-third of the root and rarely at the apical-third. The present paper ...
A microscopic analysis of the effects of root surface scaling with different power parameters of er,cr: YSGG laser
(2015)
The aim of this study was to evaluate the effects of different power parameters of an Erbium, Cromium: Yttrium, Scandium, Gallium, Garnet laser (Er,Cr:YSGG laser) on the morphology, attachment of blood components (ABC), ...
Root xylem in three woody angiosperm species is not more vulnerable to embolism than stem xylem
(2020-05-01)
Aims: Since plants are compartmentalised organisms, failure of their hydraulic transport system could differ between organs. We test here whether xylem tissue of stems and roots differ in their drought-induced embolism ...
Root-system of peanuts as affected by phosphorus fertilization
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 1994-11-01)
There have been some responses of peanut roots to phosphorus. An experiment was carried out to study peanut root growth and distribution as related to P in the soil. The cultivars Tatu, Oira and Tup4 and the lines FCA 170 ...
