The Bonarda variety has been used as a base for common red wines due to its contribution to color and low level of astringency as a consequence of its relative low tannin concentration. The use of Microwave- Assisted Ext...

Non-Saccharomyces yeasts are unicellular eukaryotes that play important roles in diverse ecological niches. In recent decades, their physiological and morphological properties have been reevaluated and reassessed, demons...

Tesis de Maestría El objetivo de la presente tesis consiste en formalizar el Péndulo de O’Donnell mediante un modelo basado en el enfoque clásico-keynesiano del valor, la distribución y la acumulación, y aplicado ...

In Survival Analysis, the focus of interest is a time $T^*$ until the occurrence of some event. A set of explanatory variables (denoted by a vector $Z$) is considered to analyze if there is a relationship between any of ...

El bicarbonato (HCO3-) es el producto de desecho de la respiración mitocondrial. Las proteínas transportadoras de HCO3- (TB) facilitan el movimiento del HCO3- para acelerar el descarte de CO2, controlar el pH celular y...

Sterol regulatory element binding proteins (SREBP), encoded by the Srebf1 and Srebf2 genes, are important regulators of genes involved in cholesterol and fatty acid metabolism. Whereas SREBP-2 controls the cholesterol sy...

Aims. Bars are considered an efficient mechanism for transporting gas toward the central regions of galaxies and potentially enhance nuclear activity. However, the extent to which bars influence active galactic nuclei (A...

Desde diversas fuentes orales analizamos la conformación de dos colectivos obreros, construidos a partir de la implantación de polos de desarrollo en la Patagonia argentina y la Amazonia brasileña. Estos proyectos tra...

Este trabajo analiza el tratamiento de la emergencia en el sistema jurídico desde la perspectiva de la conjetura planteada por Henri Poincaré en el ámbito de la topología en 1904. Una conjetura que fue resuelta final...

Coral reef systems on the southeastern Cuban shelf are exposed to rapid warming and increasingly frequent marine heatwaves (MHWs). However, the physical drivers of local sea-surface temperature (SST) variability remain...

Fe–Mn based alloys with more 12% at. of Mn are usually called High-Mn steels. Several technological properties of High-Mn steels are explained by the presence of the fcc-hcp martensitic transformation. This transition ...

We present data about the synthesis of urea from different substrates, i.e., free ammonia, glutamine and alanine in primary cultured rat hepatocytes treated or untreated with the model hepatotoxic agent thioacetamide (TA...

Extracellular nucleotides and nucleosides activate signaling pathways that play major roles in the physiology and pathophysiology of the gastrointestinal tract. Ectonucleotidases hydrolyze extracellular nucleotides and t...

Commerson’s dolphins (Cephalorhynchus commersonii) are separated into the subspecies C. c. commersonii, found along southern South America (SA) and the Falkland Islands/Islas Malvinas (FI/IM), and C. c. kerguelenensis,...

Most alpine ecosystems are subject to non-native species invasion as climate warms and human disturbance increases. Therefore, it is important to identify the main barriers and facilitators of alpine plant invasions. Whi...

A green and sustainable approach to the direct synthesis ofthioesters has been developed using Fe3O4 as a low-cost, easilyprepared, reusable and environmentally safe catalyst. The crossdehydrogenative coupling (CDC) of v...

Trade-offs between yield and grain quality for dry milling are common in maize (Zea mays L.), but the magnitude of these correlations can differ depending on the specific quality trait. We aimed to quantify the relations...

Soy protein isolate (SPI) films reinforced with starch nanocrystals (SNC) were developed by simple casting method. The films were transparent and homogeneous. The opacity and degree of crystallinity increased with the am...

A new series of heterofused thiazolo/pyrazinedione hybridswere designed, synthetized and their cytotoxicity potential wasevaluated against different cancer cell lines. Besides, druglikenessand in silico ADME/Tox studies ...

En el marco de una investigación dedicada al campo literario argentino de 1969, se examinan episodios vinculados a la circulación de la literatura chilena en Buenos Aires. En particular, el artículo se detiene en una ...
