Los estudios palinológicos y de isótopos estables de carbono y nitrógeno en heces ycoprolitos brindan información sobre dieta, estacionalidad en el uso del sitio, rango de acción delos organismos, entre otros. En el...

Exponemos de forma breve las consideraciones en torno a las ofrendas destinadas a los angelitos en el caso de los Cementerios Públicos Municipales, Provincia de Corrientes, Argentina y Sur de la Región Oriental d...

During ontogeny, complex adaptations undergo changes that sometimes entail different functional capabilities. This fact constrains the behaviour of organisms at each developmental stage. Rodents have ever-growing incisor...

Studying demographic changes in past human populations is of great interest due to their role in processes of cultural change as well as the biological evolution of populations. Despite this, a general consensus about th...

Tree growth is one of the main variables needed for forest management planning. The use of simple models containing traditional equations to describe tree growth is common. However, equations that incorporate different f...

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 ...

Este trabajo intenta relacionar los “frentes de atracción de pueblos indígenas” creado por las agencias gubernamentales brasileñas con los programas del indigenismo de las compañías hidroeléctricas para los ind...

Outstanding questions about the RNA world hypothesis for the emergence of life on Earth concern the stability and self-replication of prebiotic aqueous RNA. Recent experimental work has suggested that solid substrates an...

In this work we studied the temporal evolution of the resonant emission lines of neutral silver (Ag I) at wavelengths328.9 nm and 338.2 nm, in different surrounding media (He, Ar, Xe and air) and at different laser pulse...

Gamma-Ray Bursts (GRBs) are one of the brightest transient events detected, with energies in their prompt phase ranging from keV to GeV. Theoretical models predict emissions at higher energies in the early times of the a...

We prove that the simplicial complex whose simplices are the nonempty partial bases of (Formula presented.) is homotopy equivalent to a wedge of (Formula presented.) -spheres. Moreover, we show that it is Cohen–Macaul...

Background and aims: The transition of macrophage to foam cells is a major hallmark of early stage atherosclerotic lesions. This process is characterized by the accumulation of large cytoplasmic lipid droplets containing...

IntroductionCitizen science presents a critical pathway for advancing biodiversity monitoring and conservation globally, yet local and indigenous engagement remains limited in many developing countries.MethodsThis study ...

It was the goal of this research to examine the dynamics of Croatian transformation to market orientation and test whether the market orientation model changes with time as the business environment changes. Based on the ...

Este estudo apresenta a estrutura de florestas em Gaúcha do Norte-MT (13° 10'S e 53° 15' O), na borda sul-amazônica. Para o levantamento fitossociológico, três áreas amostrais de 1ha foram subdivididas em 50 parce...

This article presents a previously unknown thesis print which includes a depiction of the Holy Family. This thesis was produced by the Rugendases, a famous Augsburg family of engravers: in particular, we know it had been...

Abstract Although there are reports on many species of ticks infesting dogs, including from the Amazon region, simultaneous infestations by different species are poorly discussed in the literature. Therefore, this study ...

Este experimento foi realizado para avaliar o efeito de diferentes fontes alimentares sobre o aparecimento de diarréia e de alopecia em cabritos em crescimento. Foi usado delineamento inteiramente casualizado com seis d...

On 24 February 2022, Russia launched a full-scale invasion of Ukraine, marking a dramatic escalation of the conflict that had been simmering since 2014. Russian troops advanced into Ukrainian territory from Russia, Bel...

INTRODUCTION. An analysis of the sustained metaphor of “purgatory” is conducted, which unites I.S. Shmelyov’s later literary-critical essay “On Dostoevsky” with the novel “The Idiot” (1949) and his autofict...

Thermodynamic studies on phase transformation of biopolymers in solution are useful to understand their nature and to evaluate their technological potentials. Thermodynamic studies should be conducted avoiding time-relat...

The aim of this study was to develop and evaluate the bioactive properties and storage stability of microcapsules (MCs) obtained by co-encapsulation of the potential probiotic yeast Kluyveromyces marxianus VM004 and pean...
