Occurrence of cadaverine in hairy roots of Brugmansia candida
(PERGAMON-ELSEVIER SCIENCE LTD, 2001-07)
The polyamine, cadaverine, was detected in transformed root cultures of Brugmansia candida (syn. Datuira candida), a Solanaceae which produces the tropane alkaloids scopolamine and hyoscyamine. To the best of our knowledge, ...
Accumulation of hydroxamic acids during wheat germination
(1999)
Hydroxamic acids, quantified by HPLC, varied in concentration between three cultivars of wheat. Seeds, roots, leaves and the entire plants were analysed separately. No hydroxamic acids were present in seeds throughout the ...
Physiological and biochemical responses of the iron chlorosis tolerant grapevine rootstock 140 Ruggeri to iron deficiency and bicarbonate
(Springer, 2013)
Background and aims Iron (Fe) deficiency chlorosis
associated with high levels of soil bicarbonate is one
of the main nutritional disorders observed in sensitive
grapevine genotypes. The aim of the experiment was
to ...
Cellular response of human apical papilla cells to calcium hydroxide and tricalcium silicate-based cements
(BMC, 2021)
Background This study aimed to evaluate the biological response of human apical papilla cells to different calcium hydroxide formulations and three tricalcium silicate-based materials. Methods Primary cells were obtained ...
Tree seedlings respond to both light and soil nutrients in a Patagonian evergreendeciduous forest
(Public Library Science, 2017)
Seedlings of co-occurring species vary in their response to resource availability and this has implications for the conservation and management of forests. Differential shade-tolerance is thought to influence seedling ...
Real roots of nonlinear systems of equations through a metaheuristic algorithm
(Universidad Nacional de Colombia Sede Medellín, 2011)
This article describes the use of a numeric strategy to perform a metaheuristic optimization for finding the real roots of a nonlinear equation system. A theorem that shows why it can be treated as an optimization problem ...
A remark on primitive roots and ramification
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1973)
The problem on primitive roots modulo the powers of a prime ideal in a ring of algebraic integers is solved, and a connection with ramification is remarked.
Chilean growth dynamics
(ELSEVIER, 2006-03)
This paper provides a framework for analyzing the growth dynamics of Chile. Using univariate time series representations, we find that the Chilean data is more consistent with exogenous rather than endogenous growth models. ...
