In vivo or in vitro electrophysiological characterization is a standard procedure to know specific aspects of the sensory and motor fibers conduction. In this work we propose a simplified empirical modeling that can pred...

We find that for adsorbed terephthalic acid (TPA) molecules surface Sn alloying deactivates the Cu(001) surface by decoupling the adsorbed molecules from the substrate. This effect is investigated for the case of the 0.5...

Distribution of ungulates is regulated by natural factors, such as presence of other species, climate, and habitat variability, as well as human activities, including livestock grazing and mining. Understanding the spati...

El objetivo de este trabajo es analizar el proceso de transformación de la Universidad Obrera Nacional (UON) en el periodo inmediatamente posterior al golpe de Estado que destituyó a Perón, haciendo especial énfasis ...

Protein aggregation plays a central role in the pathogenesis of many neurodegenerative diseases and poses major challenges in protein engineering. A key driver of this process is the presence of aggregation-prone regions...

OBJETIVO: determinar a prevalência de depressão e ansiedade em mulheres climatéricas e os prováveis fatores responsáveis por sua ocorrência. MÉTODOS: em estudo transversal, foram selecionadas 93 mulheres que frequ...

Identificar los determinantes de la composición de especies arbóreas entre tipos de bosques tropicales altitudinalmente contrastantes incrementarán nuestro conocimiento de los principales factores y procesos que contr...

Identifying the determinants of tree species composition among contrasting altitudinal tropical forest types will improve our understanding of the main factors and processes controlling tree species' distributions and pa...

Strong coupling between light and molecular matter is currently attracting interest both in chemistry and physics, in the fast-growing field of molecular polaritonics. The large near-field enhancement of the electric fie...

A series of palladium-based catalysts were synthesized by grafting a silylated imidazolium ionic liquid onto two types of silica supports: mesoporous SBA-15 and commercial silica. The ionic liquid served as both a stabil...

In this note we demonstrate that the use of an index to standardize the fishing effort using the cpue of a standard vessel or gear is mistaken, once the cpues- catch per unit of total effort after standardization is simi...

Objetivos: os autores modificaram a espátula de Ayre original visando otimizar a colheita endocervical. O estudo verificou se a capacidade da espátula modificada em colher células da endocérvice é semelhante à obti...

Objetivos: investigar se a adição do swab de algodão à espátula de Ayre e o seu prévio umedecimento com solução salina fisiológica aumentam a obtenção de células endocervicais nos esfregaços colpocitológico...

Phosphorylated non-phosphorylating glyceraldehyde-3-phosphate dehydrogenase (EC 1.2.1.9; GAPN) found in heterotrophic cells of wheat is activated by MgCl2. The divalent cation disrupts the interaction between GAPN and a ...

En el presente artículo forma parte de un trabajo de investigación científica desarrollado con la finalidad de brindar alternativas terapéuticas, para dar respuesta a la necesidad de tratamientos adecuados para la fa...

In human populations various flexible, labile and interdependent structures (genetic, demographic, socioeconomic) co-exist, each of which can be organized in an hierarchical order corresponding to administrative entities...
