From the Point of View of the Chickens: What Difference Does a Window Make?

open access: yesAnimals, 2021
We aimed to investigate what broiler chickens prefer when given free choice between a barn side with artificial lighting only as opposed to the other barn side with natural light through glass windows and artificial light. Eighty-five 1 day-old male Cobb

Visual access to an outdoor range early in life, but not environmental complexity, increases meat chicken ranging behavior

open access: yesPoultry Science, 2023
: Not all chickens access an outdoor range when the opportunity is provided. This may be related to the abrupt change in environments from the stable rearing conditions to the complexity of the outdoor range.

On the Nature of Light [PDF]

open access: yesProceedings of the National Academy of Sciences, 1926
In a recent article in these Proceedings (1) Professor G. N. Lewis has suggested that the conflict between the quantum theory of light and the known facts of interference might be resolved by assuming that an atom never emits a quantum of light except to another atom, the possibility of transmission of the quantum being determined by the nature of the ...

Naturally light leptoquarks [PDF]

open access: yesPhysical Review D, 1995
Light first generation leptoquarks are being hunted for in HERA and at FNAL and there are various proposals for further searches in future machines. Such leptoquarks are however problematic from a theoretical point of view: Low energy precision measurements imply strong constraints on the couplings of the leptoquarks, and up till now the fulfilment of ...

Comparison of commercial broiler house lighting programs using LED and natural light: Part 1—spatial and temporal analysis of light intensity

open access: yesJournal of Applied Poultry Research, 2022
SUMMARY: Responses to shifting consumer preferences and demands for alternative rearing programs have resulted in a re-evaluation of lighting programs by the commercial broiler industry. The objectives of this study were to compare light intensity levels,
