We propose an extension of purely equational reasoning with an induction rule, to obtain an intermediate between the equational theory of an algebraic specification and its !-closure.

By PHAEDON FESSAS F EW EXAMPLES of erythrocytic inclusions due to abnormalities of the hemoglobin molecule are known. The first concerns Hb H.”2 Although the precipitates of Hgb H, such as is observed in the usual test employing brilliant cresyl blue, are produced artificially, there is evidence that some are formed spontaneously in vivo.’4 The second example is that of Hb Zurich; the precipita...

A difference in the proportions of foetal (Hb-F) and adult (Hb-A) haemoglobins between normal infants and those affected by haemolytic disease due to the rhesus factor was first reported by Jonxis (1948). His work was later extended by several investigators and the differences were confirmed. The hitherto reported studies have been concerned mainly with full-term infants and it was the purpose ...

In Southeast Asia α-thalassaemia, β-thalassaemia, haemoglobin (Hb) E and Hb Constant Spring (CS) are prevalent. The abnormal genes in different combinations lead to over 60 different thalassaemia syndromes, making Southeast Asia the locality with the most complex thalassaemia genotypes. The four major thalassaemic diseases are Hb Bart's hydrops fetalis (homozygous α-thalassaemia 1), homozygous ...

A Perron number is a real algebraic integer α of degree d ≥ 2, whose conjugates are αi, such that α > max2≤i≤d |αi|. In this paper we compute the smallest Perron numbers of degree d ≤ 24 and verify that they all satisfy the Lind-Boyd conjecture. Moreover, the smallest Perron numbers of degree 17 and 23 give the smallest house for these degrees. The computations use a family of explicit auxiliar...

I study implementation by agenda, a straightforward voting mechanism that is widely used in practice. The main result resolves an open question which dates back to Black [1958] and Farquharson [1957/1969]. It establishes that any neutral majority voting rule which satisfies the two necessary conditions identified in prior work (McKelvey and Niemi [1978]; Moulin [1986]) as well as a significantl...

It was recently revealed that epidermal growth following topical treatment with all-trans retinoic acid (atRA) was at least partly induced by heparin-binding epidermal growth factor-like growth factor (HB-EGF) released from suprabasal keratinocytes. Since proliferation of keratinocytes appears to be one of the critical roles of atRA in depigmentation treatment and promotion of wound healing, HB...

Bone has an enormous capacity for growth, regeneration, and remodeling. This capacity is largely due to induction of osteoblasts that are recruited to the site of bone formation. The recruitment of osteoblasts has not been fully elucidated, though the immediate environment of the cells is likely to play a role via cell- matrix interactions. We show here that heparin-binding growth-associated mo...
