Abstract The purpose of this paper is to describe the current status of open rotor noise prediction methods and to highlight future challenges in this area. A number of analytic and numerical methods are described which can be used for predicting ‘isolated’ and ‘installed’ open rotor tonal noise. Broadband noise prediction methods are also described and it is noted that further development and validation of the current models is required. The paper concludes with a discussion of the analytical methods which are used to assess the acoustic data collected during the high-speed wind-tunnel testing of a model scale advanced open rotor rig.

Newcastle disease is caused by Newcastle Disease Virus (NDV) leads to severe morbidity and mortality in poultry throughout the world and considered as lentogenic, mesogenic or velogenic based on the mean death of the chicken embryo. The NDV velogenic strain is deadly endemic in Pakistan. Poultry is considered as the second major industry in Pakistan having annual growth of 8-10%. Unfortunately, the increase of NDV cases leads to severe cost impact, loss of production and livelihood. This review highlights the current status and epidemiology of NDV in Pakistan. Various genotypes and sub-genotypes have been identified in Pakistan. Various ND cases have been reported in Pakistan which has very bad consequences on the economy and dealing of poultry products.
