Keel bone fractures in Danish laying hens: Prevalence and risk factors
Keel bone fractures (KBF) in commercial poultry production systems are a major welfare problem with possible economic consequences for the poultry industry. Recent investigations suggest that the overall situation may be worsening.

The debate on the role of vertical versus horizontal tectonism in Archean cratons is intimately linked to the initiation of plate tectonics. The dome-and-keel architecture has been considered as a consequence of vertical tectonism.

Simple Summary Keel bone damage is an important welfare issue for laying hens. Four lines of laying hens, differing in phylogenetic origin and laying rate kept in single cages or a floor housing system were weighed and deformities of the keel bone were ...

A hidden Rodinian lithospheric keel beneath Zealandia, Earth’s newly recognized continent
We present a data set of >1500 in situ O-Hf-U-Pb zircon isotope analyses that document the existence of a concealed Rodinian lithospheric keel beneath continental Zealandia.

Welfare parameters and keel bone damage in laying hens reared in different production systems [PDF]
The aim of this study was to determine the effect of housing system and the age of hens on welfare parameters and the prevalence of keel bone damage in laying hens. In this study two housing systems were evaluated: aviary system and enriched cages.

Keel's base point free theorem and quotients in mixed characteristic [PDF]
We develop techniques of mimicking the Frobenius action in the study of universal homeomorphisms in mixed characteristic. As a consequence, we show a mixed characteristic Keel's base point free theorem obtaining applications towards the mixed ...

Cost-Oriented Design Optimization of Single Building Curtain Wall
A building curtain wall is an outer protective structure of a building composed of a panel and a supporting structure system. As the main materials of a building curtain wall, the optimization of the keel and panel is a problem that has attracted much ...
