This resembles a fractal transform, and the coefficient values can be calculated using a least squares fit as done by Monro [3] for fractals. The major difference from fractals is that the block(x,y) values are predetermined, and therefore to render the image there is no need for the iteration associated with fractals. The RIBs are effectively the difference between the polynomial coded image a...

Rib grafts in facial plastic surgery are becoming more frequently used. Small animal models, although not ideal may be used to emulate costal cartilage-based procedures. A surgical characterization of this tissue will assist future research in the selection of appropriate costal segments, based on quantitative and qualitative properties. The objective of this study is to assess the surgical ana...

It is usually assumed that lung hernia secondary to congenital absence of ribs is a great rarity. Perasalo and Laustela (1956) describing the latest published case, of a man aged 28 years, could not find any reference to this deformity in the literature and only one of the recently published books on paediatric surgery (Swenson, 1958) mentions the malformation. Perusal of the literature, howeve...
