Bright Storage of Light

The effect of Bright light on Fatigue and sleepiness in night shift work nurses

Objective: In this study we assessed the effect of bright light emitted by light box on fatigue, and sleepiness in nurses. Methods: 44 healthy female shift work nurses were allocated into two groups of intervention and control. In the first stage, bright light was emitted to the nurses in the intervention group by the light box, and bright light was not emitted to the control group. In the nex...

طراحی شبکه برای حلقه انبارش چشمه نور ایران

The Iranian Light Source Facility (ILSF) as a national project is a 3 GeV third generation synchrotron light source facility which provides high energy super bright X-ray for the users. Design of the ILSF storage ring emphasizes an ultra low electron beam emittance (below than 5 nm.rad), beam current of 400 mA, great brightness, stability and reliability which make it competitive in the operati...

Spatial soliton pairs in an unbiased photovoltaic-photorefractive crystal circuit

: Optical separate spatial dark and bright soliton pairs in steady-state case in one dimension, for a series circuit consisting of two-photon photorefractive (PR) crystal are investigated. Each crystal can be supported the spatial soliton, and at least one must be photovoltaic. The two solitons are known collectively as separate spatial soliton pairs with dark–dark, bright–dark and bright–brigh...

Effects of light and sound stimuli on spatial distribution and swimming activity of Daphnia under laboratory conditions

Aquatic ecosystems are heterogeneous in terms of light and sound distribution. The aim of this study was to investigate the effect of environmental abiotic factors, light and sound stimuli, on Daphnia (Daphnia magna) swimming behaviour.  Here, we examined behavioural changes of Daphnia (N=24) in response to light and sound treatments simultaneously. The treatments concerned a 2×2 design with br...
