Root mass vertical distribution of perennial cool-season grasses grown in pure or mixed swards
Ciência Rural, 2021 : In this study we tested whether the root biomass of mixtures composed by grass species is greater than their respective monocultures. The treatments were monocultures of Arrhenatherum elatius, Festuca arundinacea, Dactylis glomerata, and a mixture of ...

Root architecture, root biomass and nutrient cycling in a mixed‐species agroforestry system
, 2023 Understanding root development in soil profiles of agroforestry systems is challenging. It is uncertain to what extent the proximity of cash crops, such as cocoa and coffee, to shade trees reduces nutrient concentrations in the topsoil and whether the ...

The Sex Difference in the Pathophysiology of Preterm Birth
CellsPreterm birth (PTB) refers to a labor before 37 gestational weeks. This is a major global contributor to neonatal morbidity and mortality. Although fetal sex is frequently treated as a confounding variable in PTB research, relatively few studies have ...

An integrality theorem of root systems
European Journal of Combinatorics, 2003 Let \(\Phi\) be an irreducible root system, and \(\Delta\) be a base for \(\Phi\). It is well known that any root in \(\Phi\) is an integral combination of the roots in \(\Delta\). The authors pose a natural question: If \(S\) is a linearly dependent subset of \(\Phi\), can there be a linearly independent subset of \(S\) which generates \(S\)?

Embeddings of root systems II: Permutation root systems
Journal of Algebra, 2009 In part I [\textit{M. J. Dyer}, J. Algebra 321, No. 11, 3226-3248 (2009; Zbl 1181.20036)] the author studied the embeddings of linear root systems over commutative rings. The present paper studies a class of embeddings of permutation root systems, with properties abstracting those of examples in part I.
