Given a base design with quantitative factors and a primary linear regression to each of the treatments, we may adjust secondary regressions of linear combinations of the adjusted coefficients on the primary regressions on the factor levels, thus obtaining a biregressional model. A biregressional design was established for a set of treatments, defined from quantitative factors and a linear regr...

We use a variety of combinatorial techniques to prove several theorems concerning fractional dimension of partially ordered sets. In particular, we settle a conjecture of Brightwell and Scheinerman by showing that the fractional dimension of a poset is never more than the maximum degree plus one. Furthermore, when the maximum degree k is at least two, we show that equality holds if and only if ...

The concentration of orotic acid in dry whey ranged between 64 and 146 mg/100 g and appeared dependent on whey type. The orotic acid of modified whey products, prepared commercially by electrodialysis, ultrafiltration, gel filtration, or polyphosphate precipitation was between 7 and 124 mg/100 g, which was less than that of dry whey. It appears that whey processing methods do not concentrate or...

C. F. MILLS I956 3. The organic complexes of copper in these extracts appeared to be stable in the presence of a cation-exchange resin after in vitro incubation at pH values above 2-5. Below pH 2-0 decomposition of complexes was appreciable. I wish to thank Dr J. Duckworth for his interest and encouragement and Dr R. L. M. Synge for advice on electrodialysis techniques. Thanks are due to Miss G...

The Argentinian author Silvina Ocampo (1903-1993) left us a vast body of works which are considered outstanding in many ways. In 1960, she published a short story, entitled "El médico encantador" (The Charming Physician), in the renowned literary magazine Sur. The central character of this piece is a family doctor named Albino Morgan, who had a secret truth: in any house he visited, all variety...

THE correction of electrolyte imbalance and the removal of retention products of the blood during renal failure is at present achieved by the use of artificial kidneys which permit the diffusion of solutes through a semi-permeable membrane. Several types of apparatus used successfully for hemodialysis include those described by Kolff and Watschinger (1956) and Alwall, Norviit, and Steins (1948)...
