This paper deals with an (otherwise classical) two-(non-interacting) particle system immersed in a common stochastic zero-point radiation field. The treatment is an extension of the one-particle case for which it has been shown that the quantum properties of the particle emerge from its interaction with the background field under stationary and ergodic conditions. In the present case we show that non-classical correlations—describable only in terms of entanglement—arise between the (nearby) particles whenever both of them resonate to a common frequency of (...) the field. For identical particles the entanglement becomes maximum and must be described by totally (anti)symmetric states. (shrink)

The present paper reveals (non-relativistic) quantum mechanics as an emergent property of otherwise classical ergodic systems embedded in a stochastic vacuum or zero-point radiation field (zpf). This result provides a theoretical basis for understanding recent numerical experiments in which a statistical analysis of an atomic electron interacting with the zpf furnishes the quantum distribution for the ground state of the H atom. The action of the zpf on matter is essential within the present approach, but it is the ergodic demand (...) what ultimately leads to the matrix formulation of quantum mechanics. The paper thus represents a step forward in the quest for an elucidation of the fundamentals of quantum mechanics. (shrink)

Continuous recordings of brain electrical activity were obtained from a group of 176 patients throughout surgical procedures using general anesthesia. Artifact-free data from the 19 electrodes of the International 10/20 System were subjected to quantitative analysis of the electroencephalogram (QEEG). Induction was variously accomplished with etomidate, propofol or thiopental. Anesthesia was maintained throughout the procedures by isoflurane, desflurane or sevoflurane (N = 68), total intravenous anesthesia using propofol (N = 49), or nitrous oxide plus narcotics (N = 59). A set (...) of QEEG measures were found which reversibly displayed high heterogeneity of variance between four states as follows: (1) during induction; (2) just after loss of consciousness (LOC); (3) just before return of consciousness (ROC); (4) just after ROC. Homogeneity of variance across all agents within states was found. Topographic statistical probability images were compared between states. At LOC, power increased in all frequency bands in the power spectrum with the exception of a decrease in gamma activity, and there was a marked anteriorization of power. Additionally, a significant change occurred in hemispheric relationships, with prefrontal and frontal regions of each hemisphere becoming more closely coupled, and anterior and posterior regions on each hemisphere, as well as homologous regions between the two hemispheres, uncoupling. All of these changes reversed upon ROC. Variable resolution electromagnetic tomography (VARETA) was performed to localize salient features of power anteriorization in three dimensions. A common set of neuroanatomical regions appeared to be the locus of the most probable generators of the observed EEG changes. (shrink)

Adenosine transport in cultured human umbilical vein endothelial cells (HUVEC) was characterized and shown to be mediated by a single facilitated diffusion mechanism. Initial rates of adenosine influx at 22 degrees C were saturable [apparent Michaelis constant, 69 +/- 10 mu M; maximum velocity (V-max), 600 +/- 70 pmol.10(6) cells(-1).s(-1)] and inhibited by nitrobenzylthioinosine (NBMPR). Formycin B had an unusually high affinity [inhibitory constant K-i), 18 +/- 4.3 mu M], whereas inosine had a low affinity (K-i, 440 +/- 68 mu (...) M) and nucleobases were without effect on adenosine influx. The number of transporters (1.2 x 10(6) sites/cell) was estimated by NBMPR equilibrium binding (apparent dissociation constant, 0.11 +/- 0.01 nM; maximum binding, 2.0 +/- 0.15 pmol/10(6) cells). In addition, we compared these endothelial cells with those obtained from cords from pregnancies complicated by diabetes (HUVEC-D), since embriopathy may occur in these conditions. HUVEC-D exhibited a 2.3-fold reduction in both the V-max for adenosine influx and the maximum number of NBMPR binding sites (260 +/- 40 pmol.10(6) cells(-1).s(-1) and 0.86 +/- 0.08 pmol/10(6) cells, respectively). However, the turnover number for each nucleoside transporter in normal and diabetic HUVEC was similar (approximate to 300 adenosine molecules/s). Adenosine metabolism at 10 mu M in HUVEC-D was modified compared with normal cells. Intracellular phosphorylation (> 90%) was the predominant pathway in normal HUVEC, whereas in HUVEC-D, substantial levels of adenine and adenosine were detected. The present results demonstrate therefore the downregulation of the NBMPR-sensitive nucleoside transporter and changes in adenosine metabolism in HUVEC from diabetic pregnancies. (shrink)

The last line should, I believe, be printed as a question. Strepsides is seated on the sacred and a wreath is put on his head, which makes him feel like a sacrificial victim. In 261 he is told to hold still, and we gather from that at this point he is being sprinkled with some dry substance. If we put the full stop at the end, he is saying, ‘I can see you won't disappoint me: being sprinkled like this will (...) make me into flour all right’. If we make it a question, it is ‘No fear, you won't trick me: you mean being sprinkled is the way to turn into flour?’ This seems more in keeping with his apprehension in 257, and it allows what is perhaps a more natural sense to.

Le but de cet article est une critique de la philosophie politique de M. Eric Weil. Par opposition à M. Weil, l'auteur définit la „politique" ici comme l'art du réalisable, à préciser comme : l'art d'arriver à court terme à une organisation de la société qu'on estime meilleure, et cela en employant tous les moyens permis. L'homme politique n'est pas, ainsi que l'affirme M. Weil, un „saint de Vtmiversel”, qui, en ce qui concerne l'emploi de la violence, se trouve au-dessus (...) de la loi. Ce „politicien-éducateur” est en vérité l'appui des régimes totalitaires et est d'ailleurs inconcevable en dehors de ceux-ci. En outre la théorie de M. Weil contient un certain nombre de contradictions internes et, si on la mesure à la pratique, elle se trouve être déficiente à beaucoup d'égards. Contre la conception platonicienne de M. Weil l'auteur défend la thèse que la politique n'est pas une infraction, regrettable mais inévitable, à „la morale”. C'est la tâche de l'homme politique de supprimer toutes les absurdités, inconséquences et injustices qui entachent les structures de la société. Ce qui, concrètement, est absurde, inconséquent ou injuste n'est pas déterminé par „la morale”, mais par la conscience du droit et par le sentiment moral d'une époque donnée. Les „certitudes” d'où part l'homme politique ne sont pas des Idées platoniciennes, mais des hypothèses de travail, qui dérivent leur contenu non pas de la contemplation des Idées, mais d'une notion de ce qui est juste et désirable, notion qui est déterminée par les conditions matérielles et spirituelles et qui se trouve dans un changement continuel.

The urgency of the issues discussed in the article is due to the fact that a person always stood and will be at the center of the interests of any religious structure, and especially if that structure is such an authoritative, powerful and influential Church as the Roman Catholic one. Today, centralized Catholicism presents its social position as a moral improvement of a person through cooperation with other people for the sake of a common and perfect future. The purpose of (...) the article is to examine the social concept of Catholicism, which is pervaded by the ideas of providentialism. The latter is characteristic of considering the social development of mankind in accordance with God's plan. The crown of creation of the Most High is man, so "the Church implements her plan through man, but not in the abstract, but in a concrete, living, social dimension," - says Cardinal Joseph Goffner. Through the constant evangelization of humanity, the Church seeks to influence the improvement of human life and seeks to point to Christianity as a faithful way of life. But a world where the horrors of war have been replaced by the "war of civilizations," you will not call the "war of cultures" perfect. Nor can one see the great desire of mankind for moral development, spiritual perfection, but only the desire for the accumulation of material goods. (shrink)

Many past and present events in the world clearly reflect the miserable failure of modern leadership across the globe. This has significantly contributed to the crisis of survival of humankind today. If humans and their environment are to survive, we need to search for the appropriate leadership model. To that effect this paper discusses the major tenets of the Gandhian and Machiavellian models of leadership in a comparative manner. The paper shows how and why the Gandhian model is admirable, attractive, (...) timely, relevant and redeeming, while the Machiavellian model is not. (shrink)

This volume not only provides the first critical edition with an English translation of the famous correspondence of Nicholas of Autrecourt , but also an assessment of his views and the views of those to whom the letters were addressed.
