Interactions between epilithic biofilm and local hydrodynamics were investigated in an experimental flume. Epilithic biofilm from a natural river was grown over a 41-day period in three sections with different flow velocities (0.10, 0.25 and 0.40 m s(-1) noted LV, IV and HV respectively). Friction velocities u* and boundary layer parameters were inferred from PIV measurement in the three sectio...

Human lice (Phthiraptera: Pediculidae) from Africa, America and Europe were electrophoresed for 28 enzymes, with special interest in metabolic factors likely to be involved with insecticide resistance. Zymogram profiles of the body louse (Pediculus humanus L. from France and U.S.A.) and the head louse (P. capitis DeGeer from France, Madagascar, Mali & Senegal) were compared. Only esterase two e...

This descriptive, analytical study was carried out in 2003 to determine the prevalence of pediculosis capitis and some risk factors among primary-school pupils in Kerman. We selected 1200 pupils (53% girls) from 50 primary schools by multistage, systematic random sampling. Their hair was examined for head louse infestation: 45 (3.8%) were infected with lice, 43 (95.5%) girls and 2 (4.5%) boys. ...
