Las transiciones escolares: una oportunidad de desarrollo integral para niños y niñas by Sara Victoria Alvarado, Martha Cecilia Suárez

“…En este artículo presentamos los resultados de una investigación sobre las transiciones educativas del hogar al centro de cuidado y de éste al preescolar y la primaria en niños y niñas indígenas de la comunidad Embera Chamí en Riosucio, Caldas, Colombia. Conceptualizamos las transiciones como momentos críticos de cambio que viven los niños y las niñas al pasar de un ambiente a otro, abriendo oportunidades para su desarrollo humano y su aprendizaje para la vida y la escuela, en un estudio de caso cualitativo con enfoque histórico hermenéutico. …”

The mycobacterial ABC transporter IrtAB employs a membrane-facing crevice for siderophore-mediated iron uptake by Imre Gonda, Simona Sorrentino, Laura Galazzo, Nicolas P. Lichti, Fabian M. Arnold, Ahmad R. Mehdipour, Enrica Bordignon, Markus A. Seeger

“…Abstract The mycobacterial ABC transporter IrtAB features an ABC exporter fold, yet it imports iron-charged siderophores called mycobactins. Here, we present extensive cryo-EM analyses and DEER measurements, revealing that IrtAB alternates between an inward-facing and an outward-occluded conformation, but does not sample an outward-facing conformation. …”

BMN-like sectors in 4d N $$ \mathcal{N} $$ = 4 SYM with boundaries and interfaces by Andrea Chaney, Christoph F. Uhlemann

“…We explore operators with large R-charge. We identify Penrose limits in the holographic duals with geometry AdS4 × S2 × S2 × Σ, which describe, for each theory, a spectrum of ‘seed’ operators which each give rise to a BMN-like sector described by a pp-wave. …”

Intelligent Sensor for Measurement Systems with Sinusoidal Excitation Response by U. A. Mikitsevich, A. I. Svistun, A. V. Samarina, K. U. Pantsialeyeu, A. L. Zharin

“…The aim of the work was to develop the optimal architecture and algorithms for the operation of intelligent sensors intended for use in measuring systems operating according to the sinusoidal excitation – response scheme.This paper describes the approach proposed by the authors to the construction of intelligent sensors based on modern microcontrollers, the distinctive feature of which is the continuous generation of sinusoidal excitation and reading responses in the background, as well as setting the readiness flags for data processing in the main process of the microprocessor, which ensures uninterrupted execution of background processes, the main of which is the generation of a sinusoidal excitatory action.This approach has been tested in the development of charge-sensitive surface mapping systems, such as the Kelvin probe based on a vibrating capacitor, and the surface photo voltage probe for the case of semiconductors.…”

Structural and Electrochemical Investigation of Li1.02Mn1.92Al0.02Fe0.02Cr0.02O4 - x Fx (x=0, 0.08) Synthesized by Solid-State Method by Hai-Lang Zhang, Nanchun Xiang

“…The structure and physicochemical properties of this as-prepared powder were investigated by powder X-ray diffraction (XRD), electrochemical impedance spectroscopy (EIS), and galvanostatic charge-discharge test in detail. The results reveal that the multiple doping spinel Li1.02Mn1.92Al0.02Fe0.02Cr0.02O4F0.08 have better electrochemical performance than the undoped or only metal-element doped material, which may be contributed to the multiple cation and anion doping to lead to a more stable spinel framework with good capacity retention rate.…”
