Point defects in silicon carbide are rapidly becoming a platform of great interest for single-photon generation, quantum sensing, and quantum information science. Photonic crystal cavities (PCCs) can serve as an efficient light-matter interface both to augment the defect emission and to aid in studying the defects' properties. In this work, we fabricate 1D nanobeam PCCs in 4H-silicon carbide wi...

Background: High levels of fatigue in the workplaces can lead to reduced productivity, and increase the risk of accidents and injuries. Purpose of this study was to assess and compare the fatigue levels among fixed-dayshift and rotating-shift workers of a rolling mills and steel production company in tehran. Methods: The study included 180 workers with fixed- and rotating-shift schedules. The ...

We present a numerical study of the rotating flow generated by two rotating disks in co-/counter-rotating, inside a fixed cylindrical enclosure similar to the Czochralski configuration (Cz).  The enclosure having an aspect ratio A = H/Rc equal to 2, filled with a low Prandtl number fluid (Pr = 0.011), which is submitted to a vertical temperature gradient. The finite volume method has been used ...

The purpose of this research was to suggesting a model of factors affecting on promoting the resilience of rotating staff in Iranian Oil Terminals Company. This research was conducted using qualitative method and thematic analysis based on inductive and need-based method. The statistical population of this research was the rotating staff of Iranian Oil Terminals Company. The statistical populat...

A possibility of measuring water vapor column from diffuse irradiance, and thus the extension of optical retrievals to cloudy days, was investigated. The data from the Rotating Shadowband Spectroradiometer (RSS) during its winter deployment at the North Slope of Alaska (NSA) site is used. The initial analysis covers 20 days in March 1999 that include clear, partly cloudy, and overcast days. Dur...

To determine If patients with rest angina have more severe regional Isehemla than padents with exertlonal aiigln., we compared the severity of left coronary artery (LCA) stenods In 29 patIents with transient anterior chemIc S’ -T changes at rest, and 30 patIents with anterior ST changes only during exertion. The percentage diameter stenosis w measured with Vernier calIpers (2 X lesion diameter ...

In this paper, experimental data and numerical results of heat transfer from a heated rotating disk in still air are presented over a large range of inclination angles and a dimensionless correlation is developed for forced, natural and mixed convection. The measured Nusselt number over the rotating disk is compared with the numerical results. The goal of the present research is to develop a se...
