The first cases of rabies in jackals were reported in 1952, several months after the introduction of domestic dog rabies to Zimbabwe (Foggin, 1988; Swanepoel et al., 1993). A small number of cases were reported during the following years, until 1965 when a large epidemic started in the Mashonaland East area. Since then, several distinct epidemics have been reported. Jackal rabies was reported p...

We use the corrections ∆$̇ to the standard Newtonian/Einsteinian perihelion precessions of the inner planets of the solar system, recently estimated by E.V. Pitjeva by fitting a huge planetary data set with the dynamical models of the EPM ephemerides, to put constraints on the position of a putative, yet undiscovered large body X of mass MX, not modelled in the EPM software. The direct action of...

I present detailed analysis of the near infrared spectrum of HD 3651B, a faint, co-moving wide companion to the nearby planet-hosting star HD 3651. These data confirm the companion as a brown dwarf with spectral type T8, consistent with the analysis of Luhman et al. Application of the semi-empirical technique of Burgasser, Burrows & Kirkpatrick indicates that HD 3651B has Teff = 790±30 K and lo...

We show that the anomalous retrograde perihelion precession of Saturn !& " , recently estimated by different teams of astronomers by processing ranging data from the Cassini spacecraft and amounting to some milliarcseconds per century, can be explained in terms of a localized, distant body X, not yet directly discovered in the remote periphery of the solar system. From the determination of its ...

OBJECTIVE To construct a score that allows prediction of major depressive episode (MDE) persistence in individuals with MDE using determinants of persistence identified in previous research. METHOD Data were derived from 250 subjects from the general population with new MDE according to DSM-III-R. These subjects were recruited from the Netherlands Mental Health Survey and Incidence Study (NEM...

Almost 30 years have passed since the initial publication of Ivan Illich’s Limits to Medicine. Medical Nemesis: The Expropriation of Health. A medieval historian who has been described as one of the world’s great thinkers, Illich introduced his iconoclastic work with the indictment, “the medical establishment has become a major threat to health.” The book makes a passing reference to radiology ...
