Se presenta una teoría vectorial de la difracción de haces Hermite–Gauss sobre una pantalla metálica de espesor h con dos rendijas de ancho l y separación d. los haces inciden oblicuamente con polarización TM. Estudiamos ...

Progress curves of enzymatic hydrolysis are commonly used for gaining insights on the structure and functionality of native and modified starch. Commonly, heuristic models (e.g., first-order kinetics) are used to fit the ...

A lo largo de las últimas décadas, las descargas luminiscentes han despertado un gran interés tanto en la comunidad científica como en la industria, debido a sus amplias aplicaciones en campos como la ciencia de materiales, ...

Un continuo es un espacio métrico, compacto, conexo y no degenerado. Sea C(X) el hiperespacio de todos los subcontinuos de un continuo X. Un elemento A en un subespacio unicoherente M de C(X) agujera a M si M-{A} no es ...

Corn starch is heated (100, 120, 140, and 160 °C) under air convective conditions for 4 h. Scanning electron micrograph images show that the treatment produced pores and fractures on the granule surface. Hydroxyl groups ...

A coupled resonant acoustic waveguide (CRAW)in a phononic crystal (PnC)was engineered to manipulate the propagation of ultrasonic waves within a conventional phononic bandgap for wavelength division multiplexing. The PnC ...

En el presente trabajo se realiza el desarrollo de un campo de fuerza multiproposito para investigar las propiedades de las fases condensadas de la molécula 2-(dimetilamino)etanol (DMEA), usando cálculos ab initio con la ...

Bulk Poly(N-isopropylacrylamide) (PNIPAm) hydrogels are thermally responsive polymers that undergo a sharp volumetric phase transition around its lower critical solution temperature of 33 C. The physical characteristics ...

Hunting is one of the main threats to biodiversity due to its synergistic effect with other anthropogenicactivities. Aversive hunting is a radical measure aimed at species considered threats to human health orgoods. This ...

Animals from embryos to adults experiencing stress from climate change have numerous mechanisms available for enhancing their long-term survival. In this review we consider these options, and how viable they are in a world ...
