The influence of ion irradiation on residual stress and microstructure thin films is not fully understood. Here, 5 MeV Si2+ ions were used to irradiate a 7 µm thick tungsten film prepared by magnetron sputtering. Cross-sectional X-ray nanodiffraction electron microscopy analyses revealed depth-localized relaxation in-plane compressive stresses from ?2.5 ?0.75 GPa after the irradiation, which co...

Título: Influencia de la longitud del campo en los comportamientos inter e intra -equipo en jóvenes jugadores de fútbol. Resumen: El comportamiento táctico puede verse afectado por los cambios en los formatos de juegos reducidos (SSG). El objetivo del presente estudio fue analizar la influencia de diferentes longitudes del terreno de juego en formatos SSG-de-7 jugadores en jóvenes futbolistas. ...

Pentacoordinate carbon atoms are theoretically predicted here in a ferrocene dication derivative the eclipsed-(1; C2v), gauche-(2; C2) and staggered-[Fe(Si2-?5-C5H2)2]2+(3; C2h) forms for first time. Energetically, relative energy gaps 2 3 range from ?3.06 to 16.74 ?2.78 40.34 kJ mol?1, respectively, when compared singlet electronic state of 1 at different levels. The planar tetracoordinate (pt...

In islanded ac microgrids, conventional primary control uses inner−loop cascaded linear controller and outer−loop droop to realize local voltage regulation power sharing. However, it has a poor dynamic performance fast rate of frequency change following disturbances. This paper addresses these issues by proposing modified virtual synchronous generator (VSG) control. A Laguerre functions−based d...

Deepwater lobes constitute a significant volume of submarine fans and are primarily believed to exhibit simple sheet geometry. However, recent studies interpret the geometries these deep-marine as distinct with respect complexity facies their distribution. Hence, conceptual model sediments is essential discuss associated fan lobe architecture. The present study highlights heterogeneity distribu...
