In the title compound, C(17)H(14)N(2)O(2), the hy-droxy-ethanimine group adopts an anti-periplanar conformation. In the crystal, mol-ecules are linked by O-H⋯N hydrogen bonds, forming zigzag chains running along the c axis.

In the title compound, C(11)H(23)NO(2), the piperidine ring has a chair conformation. The two hy-droxy H atoms are disordered over two positions with fixed occupancy ratios of 0.57:0.43 and 0.63:0.37. In the mol-ecule, there are two short N-H⋯O inter-actions. In the crystal, four symmetry-related mol-ecules are linked by O-H⋯O hydrogen bonds to form a cage-like arrangement, centered about the p...

We formulate general principles of building hypergeometric type series from the Jacobi theta functions that generalize the plain and basic hy-pergeometric series. Single and multivariable elliptic hypergeometric series are considered in detail. A characterization theorem for a single variable totally elliptic hypergeometric series is proved.

1 CHAPTER ONE hy do ealth ystems atter? Health systems consist of all the people and actions whose primary purpose is to improve health. They may be integrated and centrally directed, but often they are not. After centuries as small-scale, largely private or charitable, mostly ineffectual entities, they have grown explosively in this century as knowledge has been gained and applied. They have c...

A rigorous hydrodynamic theory of the A-B transition is presented. All dissi-pative processes are considered. At low interface velocities, those occurring on hy-drodynamic length scales, not considered hitherto, are most probably the dominant ones.

A theory is presented for the measurement of regurgitant flow across an incompetent valve hy injection of indicator distal to the valve and recording of time concentration curves proximal and distal to the valve. The conditions which must be met for valid measurements are examined and demonstrated by a functioning mechanical model of the heart. The method is valid regardless of the size of the ...

In their methodological review of the indices of reproducibility, Tammemagi et al. [l] mentioned the intraclass correlation coefficient, which, they say, varies “from 1 for perfect disagreement, to 0 for random agreement, and to +l for perfect agreement.” However, such an interpretation of negative values of this statistic, although previously asserted hy Deyo et al. [12], is misleading. We arg...

Conventional analysis of public goods provision aggregates individual wiltitigne.ss to pay while treatitig income as exogenous, ignoring the fact that we generate income to allow us to purclia.se utility-generating goods. We explore the implicatiotis of endogenizing the lahorlleisure decision hy explicitly considering leisure detnami in a model of public goods provision. We consider benefit ana...
