Assessment of soil-structure interaction on a 51-story building from the spectral ratio of earthquake recordings

The soil-structure interaction (SSI) can significantly alter the characteristics of recorded motions in buildings.The ratio of Fourier amplitude spectrum of the top-story accelerations to that of the foundation accelerations permits the identification of the natural frequency of the fixed-base building.In this study, records of the Chi-Chi earthqua

Determining the variation in premaxillary and dentary bone morphology that may underlie beak shape between two pure layer lines

ABSTRACT: Beak treatment is an effective method of reducing the damage inflicted by severe feather pecking (SFP) but there is significant pressure to eliminate these treatments and rely solely on alternative strategies.Substantial variation in beak shape exists within non-beak treated layer flocks and beak shape appears to be heritable.There is the
