Background and Aims: Influenza A virus subtype H9N2 have continued to circulate in domestic poultry farms in Asia since 1998. The virus circulates in live bird markets, missing link in epidemiology of avian influenza. Regarding previous studies on H9N2 viruses of Iran and having no data on this subject in Iranian live bird markets this study was conducted to analyze genetically hemagglutinin pr...

Where there is a birdstrike, there should have been a bird. Unfortunately, many reports on bird-strikes carefully recording type of aircraft and damage incurred are without reference to the bird. No bird remains had been collected or difficulties in getting these remains identified appeared unsurmountable. They are no longer. By a combination of macroscopical, microscopical and (in special case...

Integrative relations, which combine two independent concepts (e.g., ”lake” and ”bird”) into a compound representation (”lake bird”), induce lexical priming. For example, ”lake” speeds lexical decisions to ”bird” even though they are semantically dissimilar, lexically unassociated, and unfamiliar as a phrase. We report three experiments that investigate whether this integrative priming occurs p...

Cryptococcus neoformans is a fatal fungal pathogen of humans that efficiently parasitises macrophages. Birds can be colonised by cryptococci and can transmit cryptococcosis to humans via inhalation of inoculated bird excreta. However, colonisation of birds appears to occur in the absence of symptomatic infection. Here, using a pure population of primary bird macrophages, we demonstrate a mechan...

A previous conference presentation (Baltimore, 2004) introduced the subject of obscured turbo-fans and discussed it in the context of bird strikes. In such a case, the bird will have significant interaction with the internal structure of the aircraft intake during its passage from intake lip to fan and damage to the bird may well occur causing it to pose a significantly different threat to the ...

Automatic off-line classification and recognition of bird vocalizations has been a subject of interest to ornithologists and pattern detection researchers for many years. Several new applications, including bird vocalization classification for aircraft bird strike avoidance, will require real time classification in the presence of noise and other disturbances. The vocalizations of many common b...
