Compactação do solo e produção de cultivares de milho em latossolo vermelho: II - intervalo hídrico ótimo e sistema radicular Soil compaction and yield of corn hybrids in an oxisol: II - least limiting water range and root system

open access: yesRevista Brasileira de Ciência do Solo, 2009
Este trabalho teve como objetivo avaliar, no campo, a resposta de duas cultivares de milho em um Latossolo Vermelho, em seis níveis de compactação, quanto ao desenvolvimento do sistema radicular, bem como caracterizar a compactação do solo a partir do ...

Embeddings of root systems II: Permutation root systems

open access: yesJournal 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.

Digital, Three-Dimensional Visualization of Root Systems in Peat

open access: yesSoil Systems, 2020
Belowground plant structures are inherently difficult to observe in the field. Sedge peat that mainly consists of partly decayed roots and rhizomes offers a particularly challenging soil matrix to study (live) plant roots.

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

Root developmental responses to heterogeneous water and nitrogen supply [PDF]

open access: yes, 2012
Better understanding of the interaction between the soil physical properties determining water and nitrate availability and the root proliferation and gene expression components of nutrient acquisition could contribute to food security, but may have been

G 2(2) as the automorphism group of the octonionic root system of E 7

open access: yes, 1990
Karsch F, Koca M. G 2(2) as the automorphism group of the octonionic root system of E 7. Journal of Physics, A: Mathematical and General. 1990;23(21):4739-4750.A simple method is suggested for the construction of the seven-dimensional representation of ...

Root system of Jatropha curcas

open access: yes, 2021
Jatropha curcas (L.) has been studied as a reinforcing element against slope erosion to protect from the impact of raindrops provided by the plant shoot and the anchorage of the root system.

Water Use Strategies and Shoot and Root Traits of High-Yielding Winter Wheat Cultivars under Different Water Supply Conditions

open access: yesAgronomy
Drought is the most important factor limiting winter wheat yield in the North China Plain (NCP). Choosing high-yielding cultivars is an important measure to minimize the negative effects of drought stress.

Generalized root systems

open access: yesTransactions of the American Mathematical Society, Series B
We generalize the notion of a root system by relaxing the conditions that ensure that it is invariant under reflections and study the resulting structures, which we call generalized root systems (GRSs). Since both Kostant root systems and root systems of Lie superalgebras are examples of GRSs, studying GRSs provides a uniform axiomatic approach to ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
