Urban air pollution is a serious environmental problem in developing countries worldwide, and health is a pressing issue in the megacities in Latin America. Buenos Aires is a megacity with an estimated moderate Air Quali...

As the Buenos Aires Province coastline is dominated by a longshore transport from south to north, obstructions performed at the beginning of the 20th century originated the width reduction of some beaches. Fields of groi...

Several works reported wind-wave climate changes at Buenos Aires Province continental shelf. The aim of this work is to investigate the impact of these changes in the coastal processes of the region. This study is carrie...

In Argentina, the organization of waste picker cooperatives has enabled these organizations to impose their approach and point of view in the system of waste management derived from the Integrated Solid Waste Management ...

Since the early twentieth century, and even today, Buenos Aires, the capital city of Argentina, identifies itself as a modern, white, European city. This representation is based in part on the broadly-accepted notion tha...

Third-generation biomass constitutes a renewable energy source that could substitute fossil fuels. This study evaluated the biomethane potential (BMP) of Ulva sp., Codium sp. and Undaria pinnatifida through anaerobic dig...

In this article we compute the Casimir force between two finite-width mirrors at finite temperature, working in a simplified model in 1+1 dimensions. The mirrors, considered as dissipative media, are modeled by a continu...

The circumstances in which children are born and their material and intellectual resources determine their abilities and the extent to which they will be able to develop their human potential. Government policies cannot ...

In Table 2 of this article, some of the data were incorrectly published with blank space. All blank space should be replaced with periods... Fil: Acosta, Diana Belén. Universidad Nacional del Noroeste de la Provincia d...

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...

When a surface plasmon propagates along a microrough grating, it interacts with the periodic plus the random roughness and emits light into the diffuse background, which can present intensity maxima called diffuse light ...

Since it was commercially introduced in 1974, glyphosate has been one of the most commonly used herbicides in agriculture worldwide, and there is growing concern about its adverse effects on the environment. Assuming tha...

The behavioral response of a parasitoid shows the effect on host parasitism patterns at a given host distribution. As a result, an increase or decrease in parasitism intensity according to local host densities is found. ...

Richness and diversity of parasites depend on a set of interrelated factors related to the characteristics of the host, the environment and the parasites itself. In the City of Buenos Aires, rodent communities vary accor...

InMormidea paupercula (n = 6 + XY in males), the presence of a CMA3-bright band in the telomeric regions on both sexchromosomes allowed the analysis of the kinetic activity of the sex univalents and XY pseudobivalent at ...

Shape variability among individuals is important to understand some ecological relationships, since it provides the nexus between the genotype and the environment. Geometric morphometrics based on generalized procrustes ...

This paper describes an application of the ground penetrating radar (GPR) method for detecting pipe flanges. A case history is described in which GPR was successfully used to locate pipe flanges along an 8 km metal pipel...

In this work, a quantitative analysis of heavy metals Cr and Cu in fluvial sediments was carried out by Laser-induced breakdown Spectroscopy (LIBS) to assess the anthropogenic. To perform the analysis, different sediment...

We present models for single-particle dispersion in vertical and horizontal directions of stably stratified flows. The model in the vertical direction is based on the observed Lagrangian spectrum of the vertical velocity...

Effective adherence of pollen grains on the surface of the stigma is a crucial condition for tube germination and subsequent fertilization of ovules. We provide evidence, through computer simulations, that echinate and m...

We study time-optimal protocols for controlling quantum systems which show several avoided level crossings in their energy spectrum. The structure of the spectrum allows us to generate a robust guess which is time-optima...

Förster resonant energy transfer measured by fluorescence lifetime imaging microscopy (FRET-FLIM) is the method of choice for monitoring the spatio-temporal dynamics of protein interactions in living cells. To obtain an...

Obligate brood parasites neither build their own nests nor rear their offspring. Instead, they lay their eggs in nests of individuals of other species (hosts) that take care of the parasite’s progeny. Brood parasitism ...
