The presence of vortices in the ionization of hydrogen atoms by positrons at intermediate impact energies is investigated. The present findings show that a previously reported minimum in the fully differential cross sect...

RESUMO A expansão da modernidade coincidiu com a miniaturização do mundo, uma condição destacada, em muitas oportunidades, por Walter Benjamin, que afinal a transformou numa espécie de método. Seguindo essa propos...

From 2008 to 2011, several planned modifications were implemented at the RA-6 reactor in Argentina, leading to significant benefits for future BNCT treatments. New capabilities have been implemented in NCTPlan treatment ...

The digestive and metabolic characteristics at the biochemical level underlying between-habitat dietary shift of the SW Atlantic euryhaline burrowing crab Neohelice granulata under natural conditions are unknown. We made...

In this work we search for boundedness results for operators related to the semigroup generated by the degenerate Schrödinger operator Lu=−1ωdivA⋅∇u+Vu, where ω is a weight, A is a matrix depending on x and sati...

Cyclodextrins (CDs)are a family of biodegradable cyclic hydrocarbons composed of α-(1,4)linked glucopyranose subunits, the more common containing 6, 7 or 8 glucose units are named α, β and γ-cyclodextrins respectivel...

Relative vibration between two flexible subsystems can be detrimental to the performance of many engineering applications, such as optics-based instruments, machine tools, or adjacent industrial structures sharing piping...

Several species of the family Bromeliaceae are characterized by the production of proteases in unusual amounts, especially in fruits. Bromelain, an extract rich in cysteine endopeptidases obtained from Ananas comosus L.,...

The present work provides a parametric simulation tool to assist the experimental deposition of GaN and Ge-GaN material. For this purpose, a kinetic Monte Carlo (kMC) model was developed and implemented to simulate the d...

The shape memory effect in Cu–Al–Ni alloys iscaused by martensitic transformations between a metastablematrix (β phase) and one or more martensitic phases. Inthese alloys, when diffusion becomes significant, precipi...

Here, we show a unique crop response to intraspecific interference, whereby neighboring sunflower plants in a row avoid each other by growing toward a more favorable light environment and collectively increase production...

Gemini surfactants are amphiphilic molecules formed by two polar heads and two hydrophobic tails joined by a spacer between the polar groups. Their molecular structure gives them particular physico-chemical properties in...

Entender el impacto del nuevo marco normativo de alquileres tiene un elevado grado de complejidad. En este informe especial se analiza el cambio en la Ley de Alquileres, explorando los cambios que se están aconteciendo ...

The Prandtl mixing length model has been used to take into account the turbulent effects in a 30 A high-energy density cutting torch model. In particular, the model requires the introduction of only one adjustable coeffi...

Abstract Background The exponential rise in colorectal cancer surgeries among older adults combined with 30-day readmission rates as high as 25% highlights the crucial need to optimize post-discharge care. While geriatri...

Essential oils from six species of aromatic plants collected in the Catamarca Province of Argentina were evaluated for their chemical composition and repellent and insecticidal activities against beetles of the genus Car...

This contribution presents new fossil insect taxa of the order Hemiptera (Cicadomorpha, Dysmorphoptilidae, Gallegomorphoptilinae subfam. n.) from the Ischichuca Formation (late Middle Triassic to early Late Triassic) fro...

We report here the synthesis of divalent ligands containing 3-deoxy-4-thiolactose. This thiodisaccharide has been synthesized using the Michael addition of β-1-thiogalactose to the α,β-unsaturated system of sugar-deri...

The thermal stability of N,N′-bis(1-ethylpropyl)-perylene-3,4,9,10-tetracarboxdiimide (EP-PTCDI) thin films deposited on Cu(100) has been characterized by using scanning tunneling microscopy (STM), X-ray photoelectron ...

La tradición fue un problema central para las prácticas y las teorías artísticas desde el inicio de la modernidad; eso significa también que ha sido una de sus coyunturas de producción más fecundas. En la década ...

We propose systems that allow a tuning of the phonon transmission function T(ω) in graphene nanoribbons by using C13 isotope barriers, antidot structures, and distinct boundary conditions. Phonon modes are obtained by a...

"Poly(amide-triazole) and poly(ester-triazole) synthesized from d-galactose as a renewable resource were applied for the synthesis of nanoparticles (NPs) by the emulsification/solvent evaporation method. The NPs were cha...

Fil: Rietti, Sara. Universidad de Buenos Aires; Argentina. Cuando me contactaron de REDES pidiendo mi colaboración para la organización de un dossier sobre Oscar Varsavsky, ofrecí la publicación de la conferencia que...

Entre los meses de abril y septiembre de 1897, dos jóvenes argentinos, José Ingenieros y Leopoldo Lugones, publicaron quincenalmente en Buenos Aires La Montaña. Periódico socialista revolucionario, en el que figurab...
