BACKGROUND The purpose was to study hearing aid (HA) use in persons 65 years and older, and to investigate how socioeconomic and hearing related factors were associated to use of HA. METHOD This study included 11,602 persons (65 years and above) from the second Nord-Trøndelag Health Study (HUNT2) and the integrated North-Trøndelag hearing loss study (NTHLS) in 1995-1997. Audiometry was taken ...

Reassortment of influenza A virus genes enables antigenic shift resulting in the emergence of pandemic viruses with novel hemagglutinins (HA) acquired from avian strains. Here, we investigated whether historic and contemporary avian strains with different replication capacity in human cells can donate their hemagglutinin to a pandemic human virus. We performed double-infections with two avian H...

this study planed to determine appropriate planting date and proportion of alfalfa and barley in mixed cropping. experiment carried out in khair abad station of agricultural and natural resources research center of zanjan for five years (2004-2007), using split plot design which main plot was planting date (aug .15, sep.26 and oct .6) and subplot contain alfalfa to barley ratio, barley, alfalfa...

During 1998-2003, we used populations of the solitary bee Osmia lignaria Say to pollinate a commercial sweet cherry orchard in northern Utah. Bee densities released each year ranged from 1290 to 1857 females/ha, with approximately twice as many males. Female progeny produced each year were greater than parental populations released, except in 2003, when nesting was poor due to bird predation. D...

Home Agents (HA) represent a single point of failure for Mobile IPv6-based networks. To overcome this problem many solutions have been published providing reliable HA architectures. These solutions require deploying redundant HAs on each sub-network. Although these solutions effectively mitigate this problem, they do not take into account the requirements of large networks with dozens of sub-ne...
