This study was conducted to determine the effects of increasing lighting after peak production on eggs production and Hatchable Eggs in broiler breeder Hubbard F15. In this research we used from 4 growing saloons, that in per saloons were 5250 Hubbards broiler breeder hens. In this Experiment we used by Line design way of GLM for analysed data, that we considered the Effects of two parameters, ...
Background and Aim: Undesirable lighting the work environment causes visual and non-visual effects in employers. The aim of this study was to compare the quantity and quality of combined and artificial lighting in daytime and its relationship with the indexes of mental performance. Methods: This study carried out at 65 rooms and on 81 employees randomly selected from different clusters. Measur...

Background and Objectives : Efficient Illuminance, ColorTemperature (CT), Color Rendering Index (CRI) and luminance regulations are the necessary needs for designing workplaces. The aim of this study was to investigate optical components in commercial Compact Fluorescent Lamps (CFLs). Methods : In this study, 48 coil compact fluorescent lamps available at Hamadan city market with some ...
We aim at the elaboration of Information Systems able to optimize energy consumption in buildings while preserving human comfort. Our focus is in the use of state-based stochastic modeling applied to temporal signals acquired from heterogeneous sources such as distributed sensors, weather web services, calendar information and user triggered events. Our general scientific objectives are: (1) gl...
Introduction: In recent years, use of compact fluorescent lamps has increased in order to optimize energy consumption. The aim of this study was to evaluate the radiations of electromagnetic spectrum from usual compact fluorescent lamps. Methods: In this study, 48 compact fluorescent lamps from different brands and cover (warm – cool) were selected. For studied lamps, operational facto...
The exterior envelope of buildings play a significant role on the amount of energy consumption in office buildings that are located in warm climates. The present study focuses on the reduction of energy consumption by integrating daylight and artificial lights, and by changing the characteristics of exterior envelope of buildings including window coverage and dimension of buildings. Moreover, t...
There is a scarcity of descriptive data on the performance capacity of elite badminton players, whose fitness requirements are quite specific. The purpose of this paper is to investigate the physiological response of elite badminton players in a sport-specific fitness test. Twelve Hong Kong national badminton team players performed a field test on a badminton court. Six light bulbs were connect...

nanomaterials, including cadmium-based or cadmium-free colloidal quantum dots (QDs)1,2 and, most recently, metal-halide perovskites3, have emerged from academic labs to become promising luminescent component materials for optics and optoelectronics in the display and lighting industries. Working as independent players in either photoluminescence (PL) or electroluminescence (EL) mode, these mate...
