La leche de búfala constituye un excelente alimento para el consumo humano directo y para la fabricación de derivados. El objetivo de este trabajo fue realizar un estudio comparativo de la variación de pH y de los rec...

Recent studies have shown that the lower basin of the Salado River is highly polluted with copper and chromium.  In order to evaluate the effect of those metals on Notodiaptomus conifer, a representative calanoid copepo...

Freshwater science has grown and evolved extensively since its inception in the late 1800s. Many of the models and conceptual frameworks developed for and used in freshwater research were originally proposed by researche...

Black holes with a cosmological origin, the so-called primordial black holes, might have formed in the early Universe from different mechanisms. In this work, we investigate the cosmic evolution of the early Universe ins...

Macrophyte health status can influence the composition of their exudates causing different effects on zooplankton behavior and distribution in nature. We hypothesize that: (1) the release of phenolic compounds and chromo...

La investigación social llevada adelante desde la perspectiva bourdieusiana supone enfrentar un conjunto de desafíos que refieren, por una parte, al propio proceso de construcción del objeto y de producción de conoci...

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...

El objetivo de este trabajo es realizar una re-evaluación de un PSA desarrollado en la ciudad de Salta, Argentina, con enfoque específico en el análisis de las medidas de control y el cálculo de los riesgos en el per...

Nuevos derechos ambientales fueron introducidos en Argentina con la reforma constitucional de 1994. El reconocimiento constitucional de los derechos ambientales es un paso fundamental en el avance de la justicia y la ciu...

En la Argentina se están realizando esfuerzos para controlar la diseminación de unos caracoles africanos invasores traídos del Brasil, donde la especie está prohibida y, sin embargo, se ha dispersado por todo el terr...

Planetary nebulae (PNe) are pivotal for advancing our knowledge of stellar evolution and galactic chemical enrichment. Recentprogress in surveys and data analysis has revolutionized PN research, leading to the discovery ...

Los Estados Unidos fueron vistos desde comienzos de la revolución independentista como un aliado natural de la Nueva Granada por su doble condición americana y republicana. Esta persistente idea explica que, ante diver...

Chordal graphs have characteristic tree representations, the clique trees. The problems of finding one or enumerating them have already been solved in a satisfactory way. In this paper, the following related problem is s...

In few groups of parasites have the patterns of distribution been studied using quantitative methods, even though, the study of these organisms indirectly provides information on the biogeographic history of their hosts,...

The genusLotusincludes a group of forage legume species including genotypes of agronomic interest andmodel species. In this work, an experimental hydroponic growth system allowed the discrimination of growth responses to...

Light absorption in gold nanoparticles leads to metal heating that induces photothermal reshaping because of atomic surface diffusion at temperatures well below the gold melting point. In this work, we perform time-resol...

The co-production of bio-char and upgraded bio-oil by fast pyrolysis of raw and sulfuric-acid pretreated agro-industrial wastes (corn cob, sugarcane bagasse and sunfower seed hull) was investigated to valorize wastes as ...

Aquatic organisms are subject to various forcing factors that affect their structure, some of which are natural, while others result from human activities, both having variable effects. This study aimed to determine the ...

The Oriental Darter Anhinga melanogaster, ranges from Pakistan to Indonesia and the Philippines. Although it occurs in adjacent India, it has not been recorded in Bhutan. The first observation was of a live bird in a nov...

El presente trabajo informa la detección, por métodos bioquímicos, de enzimas extracelulares relacionadas con la actividad biológica de nueve cepas del complejo Metarhizium anisopliae (Metsch.) Sorokin. Se determinó...

Math anxiety has been found to be an emotional problem that has a negative effect on students' academic performance across different levels of education. This type of anxiety could be related to certain cognitive and emo...

Abstract This study explores the biological synthesis of silver nanoparticles (AgNPs) using elicitors (ML) from the beneficial bacterium Bacillus G36 and evaluates their potential to enhance bioactive compound production...

IntroductionUnder current climate change conditions, agronomic yield is compromised by limited water availability and sudden drought events throughout the plant cycle. Among the tools to overcome drought stress, benefici...
