Values of binary mutual diffusion (interdiffusion) coefficients, obtained by using the Taylor dispersion method, for aqueous solutions of γ-cyclodextrin in the concentration range from (0.002 to 0.010) mol ·dm and temperatures (298.15 and 310.15) K are reported. From these experimental results, the hydrodynamic radius values for the γ-cyclodextrin are estimated. Also, the measured diffusion coe...

A formal algorithm of a two-way stratification design described by Bryant et al. (1960) is presented. Also a simple modification is proposed which improves the design.

D r. Normand Belliveau was a true gentleman whose long association with the Can­ adian Medical Protective Association (CMPA) provided a significant bene­ fit to the medical profession. He was a distinguished surgeon who served as a CMPA councillor from 1964 to 1997. Dr. Belliveau was the first francophone to serve as the president of the CMPA (1988–95). Dr. Belliveau’s stature in the medical pr...

"Boundary vector cells" were predicted to exist by computational models of the environmental inputs underlying the spatial firing patterns of hippocampal place cells (O'Keefe and Burgess, 1996; Burgess et al., 2000; Hartley et al., 2000). Here, we report the existence of cells fulfilling this description in recordings from the subiculum of freely moving rats. These cells may contribute environm...

Understanding how comets work--what drives their activity--is crucial to the use of comets in studying the early solar system. EPOXI (Extrasolar Planet Observation and Deep Impact Extended Investigation) flew past comet 103P/Hartley 2, one with an unusually small but very active nucleus, taking both images and spectra. Unlike large, relatively inactive nuclei, this nucleus is outgassing primari...

We introduce a novel method of modelling Tullock rent-seeking contests that avoids the complexities encountered by the ‘best response function’ approach. We analyse contests in which there are many risk averse players differing in their attitudes to risk. We establish that, if every player has a constant degree of absolute risk aversion, a unique equilibrium exists. We also establish comparativ...

The discrete cosine and sine transforms are generalized to a triangular fragment of the honeycomb lattice. The two-variable orbit functions of the Weyl group A2, discretized simultaneously on the weight and root lattices, induce the family of the extended Weyl orbit functions. The periodicity and von Neumann and Dirichlet boundary properties of the extended Weyl orbit functions are detailed. Th...

A micromethod involving the use of fluorescent derivatives of 1-dimethylaminonaphthalene-5-sulphonyl chloride (Gray & Hartley, 1963) has been used in a parallel study of the structure of peptide C8Pla (as defined by Ambler, 1963) of the Pseudomonas cytochrome c-551. The basis of the method was a modification of the phenyl isothiocyanate procedure for the removal of the N-terminal residue (Edman...

This study, using National Labor Relations Board data and American Hospital Association data, reports on the status of union election activity in the hospital industry for a 65-month period, January 1980-May 1985, and contrasts it with earlier data for a similar 65-month time period (1974-79). Together these data provide a comprehensive overview of union election activity in non-Federal, nongov...
