Sir, May I comment on the recent article under the above heading in the Archives (1973, 48, 923) where Bray and Beaven are given the credit for having discovered the role of pathogenic Esch. coli in infantile gastroenteritis. It would be a pity if the much earlier work of my former teacher A. Adam was to be forgotten. In 1923 he first identified special types of lactose-splitting Esch. coli as ...

Background Rising atmospheric CO2 concentrations can increase crop yields; however, it is poorly understood if plants require higher phosphorus (P) inputs to support increased production. In addition, soils with contrasting P-sorption capacities may alter plant response elevated CO2. Aims We examined the effect of on critical soil available P and shoot for growth in capacities. Methods Response...

The common points and differences between the Bray-Liebhafsky and BriggsRauscher reactions are discussed. The reactants of the non-catalyzed version of the Briggs-Rauscher reaction being the same as those of the Bray-Liebhafsky reaction plus a reducing organic compound, the mechanisms of these two systems must have several common points. The marked difference between the oscillating behaviours ...

In a study of the metabolism of the 19 members of the chloromononitrobenzene series (for summary and references see Table 4 of Bray, James & Thorpe, 1957 b) it was observed that in the rabbit several compounds were converted into mercapturic acids by replacement of a relatively labile chlorine atom. The formation of mercapturic acid by acetylcysteyldebromination of4-bromo-3:5-dichloronitrobenze...

In a recent As I See It, Yoshioka (2008, Mar Ecol Prog Ser 368:309–310) stated that the term Bray-Curtis should only be used for doubly-standardised data, and when data counts are used to calculate similarity, the term Czekanowski is correct; by using the wrong name, it is claimed, marine ecologists demonstrate a lack of knowledge and introduce confusion. This needs to be rectified. It is incor...

Even though having some credibility in trans-disciplinary research (see e.g., Stehr and von Storch 1995, Bray and von Storch 1999, von Storch 2009, Bray and von Storch 2009 or Stehr and von Storch 2010), we may not have fully grasped the conceptions and arguments of S. Keller. What stuck to us was the complaint that the IPCC, mainly under the influence of Bert Bolin, would have failed to issue ...

We give a very general isoperimetric comparison theorem which, as an important special case, gives hypotheses under which the spherically symmetric (n− 1)-spheres of a spherically symmetric n-manifold are isoperimetric hypersurfaces, meaning that they minimize (n − 1)-dimensional area among hypersurfaces enclosing the same n-volume. This result greatly generalizes the result of Bray (Ph.D. thes...
