The names of sixteen species of Polygala (Polygalaceae) collected by Luis Née and Thaddeus Haenke during the Malaspina Expedition of 1789–1794 were published mostly by C. L. Willdenow in Species Plantarum (1802) and b...

Acute and post-acute neurological symptoms, signs and diagnoses have been documented in an increasing number of patients infected by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), which causes Coronavi...

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 the current study, the chemical composition of Baccharis spicata (Lam.) Baill. and B. punctulata DC., Asteraceae, aerial parts’ volatile oils were analysed. A higher proportion of monoterpenes than sesquiterpenes wa...

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...

The Muaco and Taima-Taima sites, in Falcón State of northwestern Venezuela, are among the earliest sites of human occupation in South America containing artifacts associated with preserved megafaunal remains and dating ...

Lithium-rich oxides (Li1.2Ni0.2Mn0.6O2) were obtained by two synthesis routes: co-precipitation method and solid-state reaction. Both materials showed a high degree of crystallinity, and XRD analysis revealed intense and...

Urban ecosystems are dynamic and complex, with human disturbances that lead to biotic homogenization. We consider the changes suffered by the diversity of tardigrades in Santa Rosa city (Argentina) under different intens...

The aim of this study was to investigate the effects of agricultural land use and periods of hydrological variability on the environmental variables, as well as macrophyte and macroinvertebrate assemblages in lowland riv...

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...

Habitat alteration reduces the biomass and diversity of arthropods, the main food resource of many birds. We study the relationship between the forest structure and composition and the abundance of the orb weber Araneus ...

We shall prove pointwise estimates for the decreasing rearrangement of Tf, where T covers a wide range of interesting operators in Harmonic Analysis such as operators satisfying a Fefferman-Stein inequality, the Bochner-...

We show that generalized symmetries cannot be charged under a continuous global symmetry having a Noether current. Further, only non-compact generalized symmetries can be charged under a continuous global symmetry. These...

The vacuum entanglement entropy in quantum field theory provides nonperturbative information about renormalization group flows. Most studies so far have focused on the universal terms, related to the Weyl anomaly in even...

Co-Immunoprecitation is a powerful and commonly used method to identify protein-protein interactions in a physiological context. Here, we report a Co-Immunoprecitation Co-IP protocol that was adapted and optimized for th...

In developing countries, the sustainable management of materials into a circular economy framework is conditioned by several constraints, being economic limitations one of the most relevant. Integrated waste management c...

We study left invariant conformal Killing–Yano (CKY) 2-forms on Lie groups endowed with a left invariant metric. We classify all 5-dimensional metric Lie algebras carrying CKY tensors that are obtained as a one-dimensi...

This work focuses on the study of a recently published dataset (Bogado et al. in ATLAS Rucio transfers dataset. Zenodo, 2020.) with data that allow us to reconstruct the lifetime of file transfers in the contexts of the ...

Winemaking is a complex process involving two successive fermentations: alcoholic fermentation, by yeasts, and malolactic fermentation (MLF), by lactic acid bacteria (LAB). During MLF, LAB can contribute positively to wi...

We study the nonrigid dynamics induced by the standard birational actions of the split unitary groups G=O_o(n,n), SU ( n,n) and Sp(n,n) on the compact classical Lie groups M = SO_n, U_n and Sp_n, respectively. More preci...

Nanocomposite films based on polypropylene and talc were used to develop food flexible packaging. Two talc samples withdifferent morphologies (micro and macro-crystalline) were employed to formulate nanocomposites with s...

In many mountain ranges of the world, glaciers provide water from melt to rivers. Also, glacier-fed rivers receive different tributaries that differ in turbidity and canopy. In this scenario, we performed a field study...

We present an introduction to some of the state of the art in reduced order and surrogate modeling in gravitational-wave (GW) science. Approaches that we cover include principal component analysis, proper orthogonal (sin...

Water pollution associated to pharmaceutical and personal care products has become a serious environmental issue. A reasonable strategy to mitigate the problem involves adsorbing materials. In particular, the use of clay...
