Teasing out the functional groups of oil-collecting bees in the light of the pollination of Nierembergia flowers
(Springer, 2021-08)
Pollination interactions between plants bearing oil-flowers and oil-collecting bees are regarded as specialized, and within the major group of bees,oil-collecting bees are considered a special functional group of pollinators, ...
Responses of functional traits in cavity-nesting birds to logging in subtropical and temperate forests of the Americas
(Nature Publishing Group, 2021-12)
Logging causes changes in habitat structure, which can potentially lead to variations in taxonomic and functional richness of biodiversity. Studies on how functional traits in birds are affected by logging operations can ...

Reduced functional connectivity within the primary motor cortex of patients with brachial plexus injury
(Elsevier, 2016-02)
This study aims at the effects of traumatic brachial plexus lesion with root avulsions (BPA) upon the organization of the primary motor cortex (M1). Nine right-handed patients with a right BPA in whom an intercostal to ...
Water quality assessment of a neotropical pampean lowland stream using a phytoplankton functional trait approach
(Springer, 2019-10-27)
The aim of this study was to test whether the water quality phytoplankton assemblage index adapted for rivers (Qr index) is useful to characterize the water quality of a neotropical stream. We were interested also in ...
Group cognitive intervention targeted to the strengthening of executive functions in children at social risk
(Universidad San Buenaventura, 2017-12)
El presente trabajo se propuso evaluar la efectividad de una intervencion cognitiva grupal destinada a promover las funciones ejecutivas en ninos en riesgo social. Se utilizo un diseño cuasi-experimental pretest–postest ...
Mehler-Heine formula: a generalization in the context of spherical functions
(Heldermann Verlag, 2020-01)
In this article, using the notion of group contraction, we obtain the spherical functions of the strong Gelfand pair (M(n),SO(n)) as an appropriate limit of spherical functions of the strong Gelfand pair (SO(n+1),SO(n)) ...
Synthesis of a soluble functionalized-silica by the hydrolysis and condensation of organotrialkoxysilanes bearing (β-hydroxy) tertiary amine groups with tetraethoxysilane
(Elsevier, 2005-07)
The hydrolytic condensation of organotrialkoxysilanes containing (β-hydroxy) tertiary amine groups generates a significant fraction of intramolecular cycles and leads to the formation of closed structures. The aim of this ...
Structural analysis of methyl 6-O-benzyl-2-deoxy-2-dimethylmaleimido- α-D-allopyranoside by X-ray crystallography, NMR, and QM calculations: Hydrogen bonding and comparison of density functionals
(Elsevier, 2012-05)
The crystal structure of methyl 6-O-benzyl-2-deoxy-2-dimethylmaleimido- α-d-allopyranoside was solved in order to gain insight into the hydrogen bond features which can be determining features in the glycosylation ...
Fuzzy group identification problems
(Elsevier, 2021-07-22)
The Group Identification Problem (“Who is a J?”) introduced by Kasher and Rubinstein (1997) assumes a finite class of agents, each one with an opinion about the membership to a group J of the members of the society, ...
