We consider tree-level scattering amplitudes for four string tachyons on AdS_3 imes {cal N} with pure NSNS fluxes. We show that in a small curvature expansion, properly defined, the amplitudes take the form of a genus ze...

We consider a class of Nichols algebras B(Lq(1 , G)) introduced in Andruskiewitsch et al. which are domains and have many favourable properties like AS-regular and strongly noetherian. We classify their finite-dimensiona...

This work presents an experimental study of the response of a liquid bridge formed between a sphere and a plane solid surface subjected to a vertical sinusoidal vibration. The amplitude and frequency of the oscillations ...

The ground state energy of a helium atom inside a spherical multilayer quantum dot as a function of the atomic impurity location inside the quantum dot has been calculated. The multilayer quantum dot is modeled by a core...

In this paper we study the effective lepton flavor violating vertex of an electroweak Z gauge boson and two charged leptons with different flavor, lk and lm, that is generated to one-loop in low scale seesaw models with ...

Abstract 5,6-Dihydrobenzo[h]quinoline derivatives 4a–f and 5a–c were prepared via condensation of the corresponding arylidenes 2, with 1-tetralone in the presence of ammonium acetate and sodium methoxide, respectivel...

Abstract Biomass-based value web approaches are increasingly promoted as sustainable pathways for improving rural livelihoods and resource efficiency in smallholder farming systems, yet empirical evidence on their liveli...

Hydrated SiO2(111) has been projected as a competent support of an anticancer drug, 5-fluorouracil (5-FU). Theoretical calculations using the Vienna Ab-initio Simulation Package (VASP) were performed to study the drug-si...

Underwater sensor networks are becoming an important field of re- search, because of its everyday increasing application scope. Examples of their application areas are environmental and pollution monitoring (mainly oil s...

The development of a novel microfluidic device that includes a circular microchannel and integrated electrodes for DNA electrophoresis is reported. The geometry of the separation channel and the arrangement of the embedd...

To develop a new strategy to target recombinant proteins to the vacuolar storage system in transgenic plants, the ability of the transmembrane and cytosolic domains of Arabidopsis receptor homology-transmembrane-RING H2-...

In the course of our studies on 3H-1,2-dithiole-3-thione synthesis, a serendipitous reactivity with á-haloketones, in the presence of excess of potassium iodide, has been observed. Instead of the expected reaction of th...

A quantitative interpretation of the schlieren technique applied to a non-thermal atmospheric-pressure oxygen plasma jet driven at low-frequency (50 Hz) is reported. The jet was operated in the turbulent regime with a ho...

Yeast biomass is a novel source for the production of biodegradable films and, joint to the incorporation of certain compounds from essential oils, it is possible to design promising active materials for food preservatio...

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...

Purple carrots (Daucus carota ssp. sativus var. atrorubens Alef.) accumulate anthocyanins in their roots, petioles and other plant parts. These flavonoid pigments represent an excellent dietary source of antioxidant and ...

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...

Among the South American Arid Diagonal (SAAD), the Argentine Arid Diagonal (AAD) constitutes an area with low precipitations (less than 500 mm) and extends from the north of the country (on the border with Bolivia), to P...

Lean duplex stainless steels (LDSS) emerged as a competitive duplex stainless steels (DSS) where Ni is partially replaced by lower cost alloying elements such as Mn and N. However, to date there has been little to no inf...

Drier conditions have been observed in Northern Patagonia, Argentina, in the last decades, affecting the pastoralism production system. In this context, two laws were promoted to foster goat and sheep production. This re...

A set of coupled Brownian motors—resulting from a noise-induced phase transition generated through an entropic mechanism, and formerly studied in mean-field approximation—is numerically integrated by Heun’s method....

In this study, we describe, for the first time, the genetic composition of the southern elephant seal Mirounga leonina (SES) breeding colony at Potter Peninsula (PP) (King George Island, Antarctica) based on a fragment o...

Background and aimsThe ability of plant microbial symbionts to enhance hosts´ fitness depends on the abiotic and biotic context, including the presence of co-existing symbionts. We studied how the presence of arbuscular...

On December 16th, 2015, the superconducting gravimeter SG038 started to measure again after it was moved from the previous station in Concepcion, Chile to the Argentine-Germany Geodetic Observatory (AGGO) near the city o...
