An interpretation of high-frequency (20–2400 Hz) fast quasiperiodic oscillations of magnetars in terms of an equivalent electric circuit is given. Observed periods and the very high quality of quasi-periodic oscillations are explained. The oscillation source is represented as a hot electron-positron plasma in a ‘trapped fireball’, a system of current-carrying magnetic loops of various sizes. Th...

http://dx.doi.org/10.1590/1806-9282.63.01.18 Spondylodiscitis affecting the cervical spine is the most unusual type. Disease progression can be dramatic, even causing quadriplegia and death. We present an unusual case that progressed with osteolytic lesions between C2 and C3, causing cord compression and epidural abscess. The patient was treated surgically by a double approach and improved with...

Nine species of Alysson Panzer 1806 are recorded from Russia and adjacent territories. The new synonymy is proposed for Alysson pertheesi Gorski 1852 =A. fuscatus var. jaroslavensis Kokujev 1906, =A. harbinensis Tsuneki 1967; Pompilus spinosus (Panzer 1801) =Alysson katkovi Kokujev 1906. The number of valid species-group taxa in the genus Alysson is reduced to 39 species. An original key to the...

Vekovima čovekova prirodna radoznalost za ljudsko telo dovodila je do stvaranja raznih instrumenata od kojih su mnogi slični današnjoj dijagnostičkoj opremi. Prvi veliki napredak u endoskopiji učinjen je u 19. veku. Filip Bocini (Phillip Bozzini, 1773–1809) opisao je 1806. godine instrument koji vizuelizuje unutrašnjost mokraćne bešike i nazvao ga lichtleiter . Okrugli otvor lichtleitera bio je...

In the last number of the Gazette I notice that Dr. McLeod, of Jeasore, relates a case of excision of the os calcis, and remarks that he io not aware that the operation has been -performed before in this country. It appears, however, that Dr. Smith had related a case in the Proceedings of the Bengal Branch of tho British Medical Association for August, 1806; and it may be worth while to state t...
