Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.

High-spin states in the odd-odd N = Z nucleus Co-54 have been investigated by the fusion-evaporation reaction Si-28(S-32,1 alpha 1p1n)Co-54. Gamma-ray information gathered with the Ge detector array Gammasphere was correlated with evaporated particles detected in the charged particle detector system Microball and a 1 pi neutron detector array. A significantly extended excitation scheme of Co-54 is presented, which includes a candidate for the isospin T = 1, 6(+) state of the 1f(7/2)(-2) multiplet. The results are compared to large-scale shell-model (...) calculations in the fp shell. Effective interactions with and without isospin-breaking terms have been used to probe isospin symmetry and isospin mixing. A quest for deformed high-spin rotational cascades proved negative. This feature is discussed by means of cranking calculations. (shrink)

Between 1234 and 1258 King Henry III, having emerged from the tutelage of ministers inherited from his father, controlled the government of England himself. Looking at this period of personal rule, it would be easy to gain the impression that Henry's kingship, in its theory, and also to some extent its practice, challenged the position of the magnates. M. T. Clanchy, for example, in a justly famous article has suggested that in the 1240s and 1250s Henry III evolved a theory (...) of royal absolutism, a theory which had threatening implications for the magnates. He has also stressed the extent to which Henry was “the initiator both of the methods and of the theory” behind Edward I's quo warranto campaign, which questioned the liberties possessed by the magnates in the field of local government. As for Henry's court, the impression has been given by R. F. Treharne that few English barons were present there, and that the king was largely surrounded by officials and foreign relatives — the latter being his wife's Savoyard uncles and his own Poitevin half-brothers of the house of Lusignan. G. W. S. Barrow has written that Henry “appeared to be excluding the barons as a class from membership of his royal council.” The question whether Henry, like his father John, was pressing magnates to pay their debts has never been investigated; but Matthew Paris's picture of the king as a “vigilant and indefatigable searcher after money” might indicate that the revolution of 1258, like that of 1215, was a “rebellion of the king's debtors.”.

Claims about ‘the meaning of life’ have tended to be made and discussed in conjunction with bold metaphysical and theological affirmations. For life to have meaning, there must be a comprehensive divine plan to give it meaning, or there must be an intelligible cosmic process with a ‘telos’ that a man needs to know if his life is to be meaningfully orientated. Or, it is thought to be a condition of the meaningfulness of life, that values should be ultimately ‘conserved’ (...) in some way, that no evil should be unredeemable and irrational. And it may be claimed that if death were to end our experience, meaninglessness would triumph. (shrink)

In this paper we examine the study of minerals from the Renaissance to the early nineteenth century in the light of the work of Michel Foucault on the history of systems of thought. In spite of a certain number of theoretical problems, Foucault's enterprise opens up to the historian of science a vast terrain for exploration. But this is the place neither for a general exegesis nor for a general criticism of his position; our aim here is the more modest (...) one of taking certain points from Foucault's study,The order of things, and seeing how far they can be extended into an area not explicitly considered in that work.

We are all waiting eagerly for the last three volumes of Toynbee's great Study of History , which has brought a new honour to British scholarship. For no English and perhaps no German writer has amassed such a wealth of information on human affairs in every age and every continent. We hope, rather anxiously, that his final diagnosis will not be to expect a “knock-out blow” from the strongest Power, which must be Russia. He is no disciple of Spengler, but (...) the downfall of the West looms before his eyes. (shrink)

R.W. Church was an English churchman and writer. Church was also famous for being the dean of St. Paul's Cathedral in London.Bacon's most famous work is his biography on Francis Bacon, the great English philosopher.

A moving cultural biography of abolitionist martyr John Brown, by one of the most important African-American intellectuals of the twentieth century. In the history of slavery and its legacy, John Brown looms large as a hero whose deeds partly precipitated the Civil War. As Frederick Douglass wrote: "When John Brown stretched forth his arm... the clash of arms was at hand." DuBois's biography brings Brown stirringly to life and is a neglected classic.

Bovine fetuin, the first fetal protein to be described, has recently been shown to be a species homologue of a well known human plasma protein ‐ α2HS glycoprotein (α2HS). The fetuins are now known to be members of the cystatin superfamily. The structural properties of the six fetuins that have been fully sequenced are compared. Despite the structural homology of these proteins, their described properties in the literature make them appear to be quite different. The diverse in vitro properties claimed (...) for fetuin/α2HS are reviewed. In vivo, fetuins are involved in the acute phase response. In development, in all species studied so far, fetuins are present in a specific cell population that forms the developing neocortex. The possible functional significance of this distribution is discussed. (shrink)

Notre époque, traversée de courants mystiques, manifeste un intérêt tout particulier pour les idées du neo-platonicien Plotin. Pour le platonicien l'univers participe à l'idée. Platon considérait les choses comme le reflet de l'idée, ce que Plotin se refusait à admettre. La diversité dont la vie fait preuve atteste son inépuisable richesse, et si les choses dans leur état particulier sont imparfaites et défectueuses, c'est que chaque chose représente sa particularité d'une façon imparfaite. Le dualisme platonicien se retrouve chez Plotin; à (...) côté du monde de l'erreur et de l'apparence il situe celui de la vérité et de la réalité. Mais l'ordre des deux mondes étant différent, nécessairement les catégories qui y règnent diffèrent. Contrairement au monde du temps et de l'espace, où tout est désaccord et combat, l'accord et l'harmonie règnent dans le monde de l'idée. D'après Platon l'idée de l'être implique l'idée du repos. Pour Plotin le mouvement et le repos ne sont pas incompatibles. Il y a encore un point de divergence entre les deux philosophes. Tandis que Platon conçoit le bien comme idée, Plotin le superpose au monde des idées et l'en sépare. A l'oppossé du maître il n'était pas dualiste mais moniste. La conception platonicienne du bien est purement éthique, c.a.d. humaine, la conception de Plotin est plus cosmique. L'univers lui apparaît comme une trinité: le monde sensoriel, le monde idéal et l'unité suprême, et il leur découvre une base commune. Tout en admettant l'imperfection du monde, Plotin nie qu'il soit mauvais et méprisable. Il se tourne contre les Gnostiques chrétiens qui prêchent le mépris du monde, et s'oppose vigoureusement aux doctrines qui font des jouissances sensuelles l'unique but de la vie. L'exercice de la vertu n'est autre chose que le moyen de s'unir à Dieu. Pour Plotin la vertu n'est donc pas une fin en elle-même, mais elle est subordonnée à un but qui la dépasse. (shrink)
