Heavy Higgs production and decay via and irreducible backgrounds at Next Linear Colliders
The complete matrix element for e^+e^-\ar b\bar bZ^0Z^0 has been computed
at tree--level and applied to --production followed by Z^0\ar b\bar b
and H^0\ar Z^0Z^0, including all the irreducible background, at Next Linear
Colliders. We find that, assuming flavour identification of the --decay
products, this channel, together with e^+e^-\ar b\bar bW^+W^- in which
Z^0H^0\ar (b\bar b)(W^+W^-), can be important for the study of the parameters
of the Standard Model Higgs boson over the heavy mass range 2M_{Z^0}\Ord

Acromegaly and gigantism in the medical literature. Case descriptions in the era before and the early years after the initial publication of Pierre Marie (1886)
In 1886 Pierre Marie used the term “acromegaly” for the first time and gave a full description of the characteristic clinical picture. However several others had already given clear clinical descriptions before him and sometimes had given the disease other names. After 1886, it gradually became clear that pituitary enlargement (caused by a pituitary adenoma) was the cause and not the consequence of acromegaly, as initially thought. Pituitary adenomas could be found in the great majority of cases. It also became clear that acromegaly and gigantism were the same disease but occurring at different stages of life and not different diseases as initially thought. At the end of the 19th and beginning of the 20th century most information was derived from case descriptions and post-mortem examinations of patients with acromegaly or (famous) patients with gigantism. The stage was set for further research into the pathogenesis, diagnosis and therapy of acromegaly and gigantism

Rosalie: the brazilian female monkey of Charcot Rosalie: a pequenina macaca brasileira de Charcot
Jean-Martin Charcot, the father of Neurology, a very austere and reserved man that did not express affection freely for human being, had a profound affection to animals, particularly to a small female monkey, called "Rosalie", which came from Brazil and was a gift of Dom Pedro II to Charcot.<br>Jean-Martin Charcot, considerado o pai da Neurologia, foi um homem de aspecto austero e reservado, que tinha dificuldades de expressar os seus sentimentos para outros seres humanos. Contudo ele tinha profunda afeição por animais, particularmente por uma pequena macaca, chamada de "Rosalie", oriunda do Brasil e que foi um presente dado a ele por Dom Pedro II
