A bayesian analysis of the world's p(γ,K^+)Λ data is presented. From the proposed selection of 11 resonances, we find that the following nucleon resonances have the highest probability of contributing to the reaction: S11(1535), S11(1650), F15(1680), P13(1720), D13(1900), P13(1900), P11(1900), and F15(2000). We adopt a Regge-plus-resonance framework featuring consistent couplings for nucleon re...

Mexicans required the stimulus of the influenza epidemic of 1918 before they established a state board of health. He describes the efforts to eradicate malaria between 1923 and 1947, and the contemporaneous success in reducing high infant and maternal death rates. After analysing changes in physician supply and distribution since statehood, Spidle concludes with an analysis ofthe growth of boar...

To explore the intracellular pathways activated by vasopressin receptors, the effects of arginine vasopressin (AVP) and its analogues mediating glycine (Gly)-induced Cl(-) currents (I(Gly)) were examined in acutely dissociated rat hippocampal CA1 neurons using the whole-cell patch recording technique. AVP and its analogues inhibited I(Gly) in a concentration-dependent manner. The inhibitory act...

According to the bibliographical data included in theWeb of Science, SCOPUS, Chemical Abstracts, and other specialized information services covering the period 1900– 1950, the first publications in mainstream journals by Mexican researchers appeared only in the first decades of the 20th century. Contrary to expectations,we find that the academic community was not the protagonist in the early st...

In this paper, a historical survey of the development entomological studies in Argentina from 18th century to 1925, year which Sociedad Entomológica was created, is presented. Three periods are distinguished survey: (a) research on insects colonial and early independent Río de la Plata, until 1870s; (b) period c. 1870 1900, entomology functioned as core around much zoological were organized; (c...

C. R. SEARLE, Eugenics and politics in Britain 1900-1914, Leyden, Noordhof International Publishing, 1976, 8vo, pp. viii, 147, Dfl. 45.00. Francis Galton (1822-1911) coined the word "eugenics", which he defined as, "the study of agencies under social control that may improve or impair the racial qualities of future generations either physically or mentally". Its objective was the increase of th...

The use of open-air treatment for tuberculosis ('pulmonary phthisis') at the Dreadnought Hospital, Greenwich from 1900 to 1905 is reviewed. A marked reduction in mean mortality rate compared to 'orthodox' management was observed.
