Background: Pre-exposure prophylaxis (PrEP) guideline implementation varies widely across countries as a result of differences in health systems, resources, and HIV priorities. Since 2016, oral PrEP has been available t...

How emotions are processed affects people´s cognition and behavior. One of the most used measures to study the physiological component of emotions is heart rate (HR), where greater HR variation (range) implies greater e...

Context. Many low-redshift active galactic nuclei harbor a supermassive black hole accreting matter at low or medium rates. At such rates, the accretion flow usually consists of a cold optically thick disk, plus a hot, l...

Pharmaceuticals can exist in many solid forms, which can have different physical and chemical properties. These solid forms include polymorphs, solvates, amorphous, and hydrates. Particularly, hydration process can be qu...

In poorly known groups for which data are insufficient to develop biologically plausible model-based approaches to phylogeographical analyses, a ‘first hypotheses’ protocol is suggested as offering the best way to ge...

1. Studying niche evolution becomes central to understanding the processesdriving species diversification along latitudinal gradients. Octodontoidea rodentsserve as a model group for understanding how the colonisation of...

Mixing calculations (i.e., the calculation of the proportions in which end-members are mixed in a sample) are essential for hydrological research and water management. However, they typically require the use of conservat...

The Pampeano aquifer formed by loess-like sediments provides water to cities and for agricultural uses in the Pampean plain, which is the most productive area in Argentina. Studies on the mechanisms through which this gr...

Green laser irradiation successfully activated self-healing processes in epoxy-acid networks modified with low amounts of gold nanoparticles (NPs). A bio-based polymer matrix, obtained by crosslinking epoxidized soybean ...

The relative importance of different processes and transitions in the appearance of non-LTE populations for the fundamental levels of ozone was studied by quantifying the kinetic law of every process and transition that ...

The links between plant diversity and ecosystem functioning remain highly controversial. There is a growing consensus, however, that functional diversity, or the value and range of species traits, rather than species num...

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...

The purpose of this paper is to study the psychometric proprieties of a new test aimed to measure scientific creativity, the Creative Scientific Ability Test (C-SAT, Sak & Ayas, 2011). The test has been validated in diff...

This article is concerned with the study of the major premises and key factors for creation of the global investment process within the frameworks of scientific and technological progress, primarily the digital and netwo...

Objetivo. Establecer la relación entre aporte sedimentario, morfologías eólicas y procesos de formación del registro arqueológico en la costa norte del Golfo San Matías (Río Negro). Para dar cuenta de ello, la met...

En este trabajo se presentan los resultados del análisis tafonómico de artefactos líticos recuperados en el sitio Arturo 4 y se exploran alternativas para comprender los procesos que intervinieron en su formación. Se...

In recent times, the development of innovative processes permits the application of a circular economy approach to the management and exploitation of mining waste with respect to human health and environment, such that s...

In this work, MCM-41 materials have been synthesized and modified with different metal loadings of iron by the wet impregnation method. The different meso-structures obtained were characterized by XRD, UVVIS-RD, ICP and ...

In volleyball games, we define a rally as the succession of events observed since the ball is served until one of the two teams on the court scores the point. In this process, athletes evolve in response to physical and ...

Introduction According to modern scholars (N. Maslova, B. Astafiev), one of the important reasons for the global planetary crisis, including modern educational system in particular, is violation of the conformity of natu...

This paper describes the next-generation ocean forecast model for the European north-west shelf, which will become the basis of operational forecasts in 2018. This new system will provide a step change in resolution and ...

"Retrieval constitutes a highly regulated and dynamic phase in memory processing. Its rapid temporal scales require a coordinated molecular chain of events at the synaptic level that support transient memory trace reacti...

A decline in the mitochondrial functions and aging are two closely related processes. The presence of estrogen and androgen receptors and hormone-responsive elements in the mitochondria represents the starting point for ...

One of the most evident costs in cow farming is the identification of the animals. Classic identification processes are labour-intensive, prone to human errors and invasive for the animal. An automated alternative is an ...
