Resentment of his wife and her involvement with the mystical Rasputin was also widespread and helped contribute to the collapse of the monarchy. Also the state of the country during World War One l...

Spencer-Attix Cavity Theory

2 Spencer Bloch And

Let X be a smooth, projective algebraic variety over an algebraically closed field k, and let H(X) denote a Weil cohomology theory. The existence of algebraic cycles on X×X inducing as correspondences the various Künneth projectors π : H(X) → H (X) is one of the standard conjectures of Grothendieck, [8], [9]. It is known in general only for the cases i = 0, 1, 2d − 1, 2d where d = dimX. The pur...

The Aristotelian principles of identity, of noncontradiction, and of excluded middle are to be supplemented by the secondorder cybernetic, or "cybernethic" principles of paradox, of ambivalence, and of control. In this paper we collect some ideas on how to eva...

In their study of 35 hemophiliac boys and young adults, 27 were considered to have adapted well at school, in the home, and with their peers, with few limitations except for those realistically imposed by the disease. In those instances of failure, difficulti...
