Hints for a fast precessing relativistic radio jet in LS I + 61° 303

Here we discuss two consecutive MERLIN observations of the X-ray binary LS I +61° 303 . The first observation shows a double-sided jet extending up to about 200 AU on both sides of a central source. The jet shows a bent S-shaped structure similar to the one displayed by the well-known precessing jet of SS 433 . The precession suggested in the first MERLIN image becomes evident in the second one, showing a one-sided bent jet significantly rotated with respect to the jet of the day before. We conclude that the derived precession of the relativistic (beta=0.6) jet explains puzzling previous VLBI results. Moreover, the fact that the precession is fast could be the explanation of the never understood short term (days) variability of the associated gamma-ray source 2CG 135+01 / 3EG J0241+6103

One-sided jet at milliarcsecond scales in LS I +61˚ 303

We present Very Long Baseline Interferometry (VLBI) observations of the high mass X-ray binary LS I +61˚303, carried out with the European VLBI Network (EVN). Over the 11 hour observing run, performed ~10 days after a radio outburst, the radio source showed a constant flux density, which allowed sensitive imaging of the emission distribution. The structure in the map shows a clear extension to the southeast. Comparing our data with previous VLBI observations we interpret the extension as a collimated radio jet as found in several other X-ray binaries. Assuming that the structure is the result of an expansion that started at the onset of the outburst, we derive an apparent expansion velocity of 0:003 c, which, in the context of Doppler boosting, corresponds to an intrinsic velocity of at least 0:4 c for an ejection close to the line of sight. From the apparent velocity in all available epochs we are able to establish variations in the ejection angle which imply a precessing accretion disk. Finally we point out that LS I +61˚303, like SS 433 and Cygnus X-1, shows evidence for an emission region almostorthogonal to the relativistic jet

Doenças de ovinos da região Central do Rio Grande do Sul: 361 casos

Foram pesquisados os arquivos do Laboratório de Patologia Veterinária (LPV) da Universidade Federal de Santa Maria (UFSM) e revisados os diagnósticos de doenças de ovinos realizados entre 1990 e 2007. No período estudado foram realizados 19.476 exames de animais domésticos. Desses, 6.816 (34,9%) correspondiam a necropsias e 12.660 (65,1%) a exames histopatológicos realizados em materiais enviados por veterinários de campo. Materiais provenientes de experimentos em ovinos foram excluídos deste estudo, sendo obtidas 354 (5,1%) necropsias e 163 (1,2%) exames histopatológicos de ovinos. O diagnóstico foi conclusivo em 265 (74,8%) casos de necropsias e em 96 (59%) casos dos exames histopatológicos, somando 361 casos conclusivos. Esses casos foram divididos em grupos conforme a etiologia: 150 casos (41,6%) de intoxicações e toxiinfecções; 142 casos (39,3%) de doenças infecciosas e parasitárias; 31 casos (8,6%) de doenças metabólicas e nutricionais; 13 casos (3,6%) de neoplasmas e lesões tumoriformes; sete casos (1,9%) de distúrbios causados por agentes físicos; seis casos (1,7%) de distúrbios iatrogênicos; e quatro casos (1,1%) de distúrbios do desenvolvimento. Oito casos (2,2%) foram classificados em outros distúrbios por não se enquadrarem em nenhum dos outros grupos. Hemoncose e intoxicação por Nierembergia veitchii foram as doenças mais importantes para ovinos nesses 18 anos.
