Este artículo presenta un análisis de la relación entre espectralidad, memoria histórica y memoria rural en la literatura española contemporánea. Interrelacionando aspectos teóricos de las tres áreas, pretendemos...

We identified six fossil-species of angiosperms based on fossil woods from two small collections from the Beta Member (lower Campanian) of the Santa Marta Formation on James Ross Island: 1) Paraphyllanthoxylon antarcticu...

Se presentan registros adicionales de Atelopus nahumae y Atelopus laetissimus en la Sierra Nevada de Santa Marta (Magdalena), Colombia, y una caracterización actual de su ecosistema. Las especies son endémicas del maci...

Different morphotypes of vertically embedded ammonoid shells are abundant in the 1-km-thick deposits of the Santa Marta Formation, Antarctica, that record the evolution of a deep-water delta system. Vertical shells depos...

An equivalence between the category of MV-algebras and the category (Formula presented.) is given in Castiglioni et al. (Studia Logica 102(1):67–92, 2014). An integral residuated lattice with bottom is an MV-algebra i...

A palynomorph with an unequivocal relationship to the eight-grain polyads of the mimosoid genus Calliandra Benth., is described from the Miocene sediments of San Juan Province, Argentina. Comparison of the fossil palynom...

Aging causes changes that affect functioning of cognitive processes such as cognitive flexibility (CF). Given it allows changing both behavior and thinking in dynamic contexts, it constitutes an essential trait of adapti...

Este artículo se ocupa del potencial de las pedagogías descoloniales—específicamente interpretadas aquí como comprometidas simultáneamente en los dominios de la investigación narrativa y la formación docente—e...

The spin trapping technique using 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) was used to investigate the involvement of phosphate radicals in TiO2-photocatalyzed systems. A persistent (HO)2PO2–DMPO˙ adduct (aN = 14.6...

Information on the variability of wild bean populations and landraces is essential to set conservation strategies and design breeding programmes aimed at enlarging the genetic base of commercial beans. Nineteen Argentine...

ABSTRACT The Neotropical otter, Lontra longicaudis (Mustelidae) is a semi-aquatic mustelid that exploits a variety of freshwater habitats. To understand the relative influence of human activities and environmental factor...

Polymer composites of epoxy resin and Nb2O5 doped BaTiO3 were prepared in the form of film (thickness 30-300 μm) using a dipping technique. Samples containing various amounts of ceramic filler were examined by thermal a...

We present a novel ultimate bound and invariant set computation method for continuous-time switched linear systems with disturbances and arbitrary switching. The proposed method relies on the existence of a transformatio...

It is shown that the anapolar interaction of the electrons of a molecule with an external uniform magnetic field B and a uniform curl C = × B′ determines different thermodynamic stabilization of the ground state for t...

Fluvial basins located on the NE side of the Sierra de Aconquija and facing the Tafí valley (NW Argentina) enable a study of the sedimentary records of valleys and alluvial fans that have been subject to glacial and per...

The geomorphological map of the alluvial fans in the Colalao del Valle-Quilmes area represents the first detailed map of the Santa María Valley, Northwest Argentina. The map was made using photointerpretation of aerial ...

A regional raw clay was used as the starting material to prepare iron-pillared clays with different iron contents. The catalytic activity of these materials was tested in the heterogeneous photo-Fenton process, applied t...

Lattice structures composed by parallel members named chords (or legs for vertical configurations) and connected by diagonals are very common among steel constructions in Civil and Mechanical Engineering and in particula...

Abstract Background The global expansion of Aedes aegypti and Aedes albopictus mosquitoes has intensified arboviral epidemics, generating annual socio-economic losses exceeding 2 billion US dollars, mainly in the America...

Abstract Background Population ageing presents increasing challenges for health systems. Identifying complex needs and planning individualized care through Comprehensive Geriatric Assessment (CGA), promoting intergenerat...

Objetivou-se obter os índices de diversidade genética para o SNP (single nucleotide polymorphism) do íntron 4 do gene da osteopontina (OPN) para 434 animais (87 touros e 347 vacas) participantes do Teste de Progênie ...

Scars are formed when a defect in the dermis is replaced with fibrous connective tissue. Sometimes scars limit the range of motion as a result of contractures. In addition, they are a source of severe subjective complain...
