The main problem encountered in pulmonary artery banding is the difficulty in determining the optimal perimeter of the band, and sometime repeated surgical operations are required to adjust the band perimeter in order to control the pulmonary blood flow. To overcome these difficulties EndoArt S.A. (Lausanne, Switzerland) developed an externally adjustable, telemetrically controlled device for p...

The revision of main and alternative banding sequences in chromosome I (AB) have been made for all 14 species of the Chironomus plumosus (Linnaeus, 1758) group. New version of mapping had been suggested for 14 out of 22 banding sequences of arm A. Mapping of 18 banding sequences in arm B have been made for the first time according to Maximova-Shobanov system. Phylogenetic relationships of the b...

FoR TnE past several years the writer has conducted a series of observations and banding studies on the Bank Swallow (Riparia r. riparia) in the Lake Okoboji region, northwestern Iowa and in the Albany and Oneida Lake regions, New York State. Although these investigations have not been terminated, they have reached a stage where similar inquiries may be profitably undertaken with some closely r...

Fixed chromosome preparations subjected to treatments such as pH 9 (I) or trypsin hydrolysis (2) and stained with Giemsa's demonstrate similar banding patterns irrespective of the pretreatments used. It has been shown that this phenomenon is the result of modifications of DNA-protein and protein-protein associations which alter dye interaction (3-5). It appears that only Giemsa's or related sta...

This article describes a conceptual framework for understanding consumer product-colour purchase decisions. Building on previous work, new primary factor, colour association, is introduced. The purpose of this study to test whether consumers' colour-associations connect with their and colour-association affects intended used two research activities (a laboratory experiment an interview) methods...

Consider two small rectangular windows, each of which is centered at a different pixel in two di erent color images. Correlation is the process of computing the similarity between these two windows. If the camera rotation between the two images is not large then if these two pixels represent the same physical surface point then the similarity, and hence the correlation value, should be high. Wh...

Let c : E(G) → [k] be a colouring, not necessarily proper, of edges of a graph G. For a vertex v ∈ V , let c(v) = (a1, . . . , ak), where ai = |{u : uv ∈ E(G), c(uv) = i}|, for i ∈ [k]. If we re-order the sequence c(v) non-decreasingly, we obtain a sequence c∗(v) = (d1, . . . , dk), called a palette of a vertex v. This can be viewed as the most comprehensive information about colours incident w...

What is the minimum amount of information we must transmit along with greyscale values in order to recover a colour original from a grey image? The problem of colour quantization is one of long standing with, for example, a GIF file consisting of single-byte grey values (appropriately compressed using entropy coding) plus a 256×3 colour lookup table in the file header. That lookup table can be ...

The influence of congenital colour defects on a clinical computer test for equiluminous colour discrimination is studied. Differences in relative spectral sensitivity and changes in colour contrast discrimination are two distinct manifestations of the abnormal genes responsible for congenital red-green defects. The very simple and rapid method of the heterochromatic flicker brightness test acts...
