Urban environments require careful consideration of numerous design factors in order to provide unique character, attractive settings and amenities, as well as safe surroundings. Appropriate lighting design is one of the factors contributing to successful urban environments. Wellington’s Civic Centre in the heart of New Zealand’s capital city serves as the setting for a case study exploring cre...

. light is an environmental factor, which has profound influences on broilers performance and frequently overlooked management practices. this study was conducted to compare the effects of different lighting programs on growth, carcass parts and economical performance using 320 one day–old broilers (arian 386) in completely randomized design with 4 treatments and 8 replicates per each treatment...

Lighting plays a key role in night escapes of urban spaces, in a way that it can be effective in giving identity to them. By considering this importance and inexistence of a process for composing urban Lighting strategy made this study to be conducted by the objective of providing process for compilation of context-oriented lighting strategy in urban spaces. Reaching a suitable solution for Li...

this study was conducted to compare the effects of different illumination programs on the cellular and humoral immune system using 320 one day–old male broilers (arian 386) in a completely randomized design of 8 replications (10 birds each). the four assayed lighting schedules were comprised of: 1- continuous lighting (control), 2- decrease then sudden increase of lighting, 3- decreasing-gradua...

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, ...
