In this paper, we propose a novel microstructure fiber with annular core for transmitting optical orbital angular Foods Dry momentum (OAM), and the OAM modes are calculated under different structure parameters of the fiber.Compared with the previous hollow step-index ring fiber, the proposed fiber brings higher refractive index contrast between the
In the oil and gas industries, understanding the behaviour of a flow through an annulus gap in a vertical position, whose outer wall is stationary whilst the inner wall rotates, is a significantly important issue in drilling wells.The main emphasis is placed on experimental (using an available rig) and computational (employing CFD software) investi
Many previous techniques for the isolation of endogenous retroelements such as LINE-1 retrotransposons have produced major sampling bias or required laborious procedures.These problems led to the isolation of only older elements in some cases.In other cases, specialized systems were required for the NEFF N1AHA02N0B N50 Built In 59cm Warming Drawer
Models of visual attention rely on visual features such as orientation, intensity or motion to predict which regions of complex scenes attract the gaze of observers.So far, Shorts sound has never been considered as a possible feature that might influence eye movements.Here, we evaluate the impact of non-spatial sound on the eye movements of observe
The study aimed to find out how to develop an optimal and effective motivation model considering the preferences and requests of young researchers, in view of the fact that scientific specific of building and organising an internal work system, its scientific potential and resources, which provides a valuable fundamental insight.The task of the stu
