Viroses confundíveis com febre aftosa

Nephropathy and viroses.

The kidneys often are involved during viral diseases, but seem to be peculiarly resistant to injury in contrast to other organs and tissues. They rarely bear the brunt of infection. Clinical evidence of viral nephritis or nephrosis seldom is of serious import and when it occurs it may be indistinguishable from that of other cause unless specific diagnostic criteria are fulfilled. With increasin...

A Case of Petechiœ Sine Febre

Sydenham, Locke and Sydenham's De peste sive febre pestilentiali.

The second edition of Sydenham's Methodus curandifebres (1668) had an added chapter on plague and its treatment which he reprinted virtually unchanged in his later book, Observationes medicae (1676, and subsequent editions). This chapter has an interesting paragraph which is unique in Sydenham's work: it mentions the opinions of other writers. Its origin appears to lie in Sydenham's association...

Visualization Dot Com

In this article, we explore the seemingly well-worn subject of distance-based, or remote visualization. Current practices in remote visualization tend to clump into two broad categories. One approach, which we’ll call render-remote, is to render an image remotely, then transmit the image to the user. Another option, render-local, transfers raw data to the user, where it is then visualized and r...

Criptografia com Curvas Elípticas

This paper presents an overview of the use of elliptic curves in cryptography. The security of this cryptosystem is based on the discrete logarithm problem, which appears to be much harder compared to the discrete logarithm problem in other cryptosystems. An overview of common cryptosystems is given, such as Diffie-Hellman and RSA, and an elliptic curve cryptography scheme is discussed. -------...
