In Ireland, the herd prevalence of bovine tuberculosis has remained stable for several decades, and in common with several other countries, progress towards eradication has stalled. There is evidence in support of the potential role of infected badgers (Meles meles, a protected species) in bovine tuberculosis in Ireland and Britain. However, this evidence(More)
During the period March 1996-July 1997, 417 heads of Awassi sheep slaughtered at the Irbid Abattoir (northern Jordan) were examined for the three larval instars (L1, L2 and L3) of Oestrus ovis. Of the 417 heads, 242 (58%) were infested with O. ovis larvae. Larval numbers were highly aggregated. The lowest number of larvae and the lower quartile were both(More)
In Ireland, the badger Meles meles L is a reservoir species for Mycobacterium bovis and, as such, contributes to the maintenance of bovine tuberculosis in cattle. A previous estimate of the badger population in the Republic was 200,000 badgers. In the current study, we obtained data on badger numbers from a large-scale badger removal project (the Four-Area(More)
We examined the effect of varying levels of badger population control on the prevalence of Mycobacterium bovis infection in badgers in four counties of Ireland. In the 'Removal' and 'Buffer' areas, proactive culling was conducted to substantially reduce and subsequently maintain badger populations at a low level for five years. In the 'Reference' areas,(More)
A base-line survey of Echinococcus granulosus, Taenia hydatigena and T ovis were undertaken in order to investigate the transmission dynamics of these parasites in northern Jordan. Intensity of E. granulosus infection, in sheep, increased with age in a linear fashion whilst the asymptotic prevalence was one. This implied that E. granulosus is in an endemic(More)
During the last several decades in Ireland, there has been substantial scientific progress in our understanding and related policy changes in the bovine tuberculosis (bTB) eradication programme. A range of performance measurements are routinely available, each highlighting a steadily improving situation in Ireland. However, recent research has highlighted(More)
The risk of a confirmed tuberculous herd restriction was examined using a logistic model for herds involved in the East Offaly Badger Research Project, Ireland, from 1988-1995. Cattle herds present in the badger-removal area had a significantly lower proportion of new confirmed tuberculous herd restrictions compared with cattle from an area where no(More)
Open-loop active flow control is used to modify the spanwise distribution of circulation around an NACA 0012 and flat plate wing. The leading edge on both airfoils and tip regions of the NACA airfoil contain spatially localized actuators that can be independently controlled in terms of amplitude and frequency, allowing the spanwise distribution of(More)
