Hydrotropism in lateral but not in pivotal roots of desert plant species under simulated natural conditions
(Springer, 2014-12)
Aims
Root hydrotropism has been widely studied in seedling radicles through artificial experiments that reduce the influence of gravity and soil. In this work we aimed to study hydrotropism of primary lateral and pivotal ...
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 ...

ROOT PROBLEM FOR CONVENIENT MAPS
(JULIUSZ SCHAUDER CTR NONLINEAR STUDIESTORUN, 2010)
In this paper we study when the minimal number of roots of the so-called convenient maps horn two-dimensional CW complexes into closed surfaces is zero We present several necessary and sufficient conditions for such a map ...
Root morphological traits related to phosphorus-uptake efficiency of soybean, sunflower, and maize
(Wiley VCH Verlag, 2015-10)
Many of the plant acquisition strategies for immobile nutrients, such as phosphorus (P), are related to the maximization of soil exploration at minimum metabolic cost. Previous studies have suggested that soybean (Glycine ...
Trade-off between root porosity and mechanical strength in species with different types of aerenchyma
(Wiley Blackwell Publishing, Inc, 2007-05)
The objective of this work was to study the existence of a trade-off between aerenchyma formation and root mechanical strength. To this end, relationships among root anatomical traits and mechanical properties were analysed ...
Influence of dental exposure to oral environment on smear layer removal and collagen exhibition after using different conditioning agents
(2011-12-28)
Although in vitro studies have shown encouraging results for root surface conditioning with demineralizing agents, in vivo studies have failed to show its benefits in periodontal healing. This can be attributed to several ...

Restrictive water condition modifies the root exudates composition during peanut-PGPR interaction and conditions early events, reversing the negative effects on plant growth
(Elsevier France-editions Scientifiques Medicales Elsevier, 2019-09)
Water deficit is one of the most serious environmental factors that affect the productivity of crops in the world. Arachis hypogaea is a legume with a high nutritional value and 70% is cultivated in semi-arid regions. This ...
