The concept of individuality in quantum mechanics shows radical differences from the concept of individuality in classical physics, as E. Schrödinger pointed out in the early steps of the theory. Regarding this fact, so...

Latin American countries have been historically characterised by production structures highly reliant on natural resources. The recent diffusion of modern biotechnologies has reinforced this specialisation pattern. The c...

Objective: Teaching is a profession associated with high burnout levels due to its very nature. During the COVID19 pandemic, teachers in Latin America were expected to adjust to remote teaching. The effect this had on bu...

The preservation and cementation of sedimentary structures under the influence of  microorganisms in siliciclastic environments have been poorly studied in contrast to carbonatic settings, where they have been extensive...

In this work we propose an automatic low cost procedure aimed at classifying legume species and varieties based exclusively on the characterization and analysis of the leaf venation network. The identification of leaf ve...

Neurotensin (NT) is a tridecapeptide distributed in central and peripheral nervous systems, which can behave as a neurotransmitter or neuromodulator at central and peripheral levels. Herein we tested the potential effect...

Optimal conditions for the industrial extraction of total polyphenols from maté (Ilex paraguarien- sis) were determined using response surface methodology, with two independent variables: ethanol percentage of the extra...

Kinetic studies of 2-chlorophenol photocatalytic degradation are carried out in a batch stirred built in quartz laboratory scale, using TiO2 as catalyst photoactived with ultraviolet light. Experimental design is per...

In the late nineteenth century, Argentina decided to construct a military port . The young officer Félix Dufourq and the Italian engineer Luigi Luiggi defined its location 700 km south of Buenos Aires (38º 53'' S, 62º...

En este libro, la Dra. Graciela Tonon compila un conjunto de experiencias teóricas y empíricas que nos permiten acercarnos al complejo abordaje de las desigualdades urbanas de forma multidimensional y multiescalar, y c...

The widely distributed pollutant tributyltin (TBT) was analyzed in different environmental samples (waters and sediments) combining preconcentration on a nylon membrane, excitation–emission fluorescence matrices direct...

The organochlorine insecticide endosulfan (ES) is widely used despite its high toxicity to fish (96-h LC50 median value of 2.6γgL-1). This study aimed to assess the acute toxicity, histological and physiological paramet...

Aims: The objective of this work was to study the influence of the sugar source on exopolysaccharide (EPS) production and the activities of the enzymes involved in the synthesis of sugar nucleotides in Lactobacillus case...

Migration of developing germ cells from the basal to the adluminal compartment of the seminiferous epithelium requires extensive tissue restructuring, resulting in the production of reactive oxygen species. Sertoli cells...

The anisakid species Contracaecum pelagicum Johnston and Mawson, 1942, is reported for first time at 2 different sites on the Argentine coast (Península Valdés, 42°04'S, 63°38'W and Mar del Plata, 38°05'S, 57°38'W)...

Not all species are likely to be equally affected by habitat fragmentation; thus, we evaluated theeffects of size of forest remnants on trophically linked communities of plants, leaf-mining insects, and theirparasitoids....

The mechanism by which insulin increases diacylglycerol kinase (DAGK) activity has been studied in cerebral cortex (CC) synaptosomes from adult (3–4 months of age) rats. The purpose of this study was to identify the ro...

In this article we show that the only 2-step nilpotent Lie groups which carry a non-degenerate left invariant Killing–Yano 2-form are the complex Lie groups. In the case of 2-step nilpotent complex Lie groups arising f...

Coccolithophores are organisms with distribution largely controlled by temperature and availability of nutrients. For extinct calcareous nannofossils there are some uncertainties in assigning ecological preferences of ta...

Hydrogen is widely considered a promising green energy vector. It may be produced by steam reforming of methane which may be obtained from renewable resources such as biogas or biomass gasification. Nickel catalysts supp...

Bone and cartilage regeneration can be improved by designing a functionalized biomaterial that includes bioactive drugs in a biocompatible and biodegradable scaffold. Based on our previous studies, we designed a vanadium...

In Lake Mascardi (Patagonia), 2 acanthocephalan species, Acanthocephalus tumescens and Pseudocorynosoma sp., share an amphipod intermediate host but have different definitive hosts. Because both acanthocephalan species a...

In this paper, we consider a general regression model where missing data occur in the response and in the covariates. Our aim is to estimate the marginal distribution function and a marginal functional, such as the mean,...
