En este trabajo se desarrolla una estrategia de control no lineal para un convertidor electrónico de potencia DC-DC reductor (convertidor buck) que alimenta una carga de potencia constante. Debido a la no linealidad que...

ABSTRACT For different dyes like methyl green, methyl orange, methyl red, malachite green, crystal violate, safranin, and methylene blue. We calculated their optical constants like wavelengths of maximum absorption, mol...

This study aims to develop an alternative method for the determination of the chemical equilibrium constant (Kc) of thiocyanatoiron(III) complex ion, based on colorimetric analysis of smartphone-captured images. The vari...

Ereymatermes Constantino is a nasute genus endemic to the Neotropical region, which included Ereymatermes rotundiceps Constantino from the forest of the lower Japurá River, AM, Brazil, and E. panamensis Roisin from the ...

Abstract Large numbers of thecamoebae are found in the sand and detritus substrate of small streams in the Amazonian terra firme forest. Their relative population densities can be determined by searching and counting the...

Aims. We investigate whether viscous cold dark matter (vCDM) in a Λ-dominated Friedmann-Lemaître-Robertson-Walker (FLRW) universe can alleviate the Hubble tension, while satisfying thermodynamic constraints. Here, we e...

Four experiments were conducted to study the requirements of available phosphorus (aP) for commercial male broilers of 1-10 day of age (exp.1), 11-21 days of age (exp. 2), 22-33 day of age (exp. 3) and 34-46 days of age ...

Abstract Limited knowledge exists regarding the use of lidocaine as a prokinetic in ruminants and camelids to treat gastrointestinal ileus. In this retrospective study, ruminant and camelid cases diagnosed with ileus and...

The aim of this paper is to examine the dynamics of scientific productivity and visibility for Web of Science (WoS) Core Collection articles that include at least one author affiliated with ”Constantin Brâncuși” ...

Temporal and spatial tuning of the refractive index of optical thin films is desired for flat optics applications. The redistribution of mobile ions in mixed ionic-electronic conductors (MIEC) has been demonstrated to se...

In recent years, the flipped learning (FL) model has emerged as an innovative and increasingly popular approach to education, transforming how students engage with content and enhancing overall learning outcomes. This mo...

This study investigates the temperature-dependent development and life table parameters of the predatory bug Orius albidipennis (Reuter, 1884) (Hemiptera: Anthocoridae) under three constant temperatures (20, 25, and 30°...

We propose to generalize Bekenstein model for the time variation of the fine structure "constant" αem to QCD strong coupling constant αS. We find that, except for a “fine tuned” choice of the free parameters, the e...

En el cálculo de la constante de velocidad de absorción de primer orden para medicamentos que se comportan de acuerdo al modelo bicompartimental, es muy importante considerar algunas fuentes de error inherentes al mét...

Three recently proposed constant temperature molecular dynamics methods by: (i) Nosé (Mol. Phys., to be published); (ii) Hoover et al. [Phys. Rev. Lett. 48, 1818 (1982)], and Evans and Morriss [Chem. Phys. 77, 63 (1983)...

There are few phenomena in condensed matter physics that are defined only by the fundamental constants and do not depend on material parameters. Examples are the resistivity quantum, h/e2 (h is Planck's constant and e th...

We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the redshift range 0.16 z 0.62. The luminosity distances of these objects are determined by methods that employ relations between SN I...

We present a new continuum solvation model based on the quantum mechanical charge density of a solute molecule interacting with a continuum description of the solvent. The model is called SMD, where the "D" stands for "d...

For strongly chaotic classical systems, a basic statistical–mechanical connection is provided by the averaged Pesin-like identity (the production rate of the Boltzmann–Gibbs entropy SBG=−∑i=1Wpilnpi equals the su...

The classic Dukhin-Shilov theory for the thin double layer polarization of colloidal suspensions in binary electrolyte solutions was developed for symmetric electrolytes: equal counterion and co-ion valences. A rigorous ...

This paper investigates the relationship between European Union (EU) funds and Romania’s general government budget deficit over the period 2009–2023. Using annual budget execution data and macroeconomic indicators ...

The cooperative movement in Romania represented a solution for improving the economic and social conditions of the population, especially in rural areas. This paper tracks the evolution of this movement from the 19th ...

This paper examines the cooperative movement as a key component of the social economy. Defined by democratic control and mutual aid, cooperatives provide inclusive solutions for both economic and social challenges. B...
