The research draws on film theory (in order to define methods to perform automated editing, to model the fundamental units of the image and the conceptual relationships between image, shot and sequence); on narrative an...

Because complex span tasks were designed to create a demanding concurrent task, the average span is usually lower (4 ± 1 items) than in simple span tasks (7 ± 2 items). One possible reason for the higher span of simple span tasks is that participants can take profit of the spare time to chunk a few stimuli into 4± 1 groups. It follows that the respective spans of these two types of tasks could ...

A survey of 65 freestall-housed dairy herds in five different countries, with an average of 1023 milking cows, found that footbaths were used 1-4 times per day for 1-7 days per week, with between 80 and 3000 cows passing through the bath between chemical changes. The most common agents used were copper sulfate (41/65) and formalin (22/65). Twenty-seven herds (42%) used more than one chemical. T...

Two groups of Trypanosoma congolense isolates collected from cattle in 1996 (n=39) and 2003 (n=38) in the Eastern Province of Zambia were analyzed by BclI-PCR-RFLP to assess the evolution of diminazene aceturate (DA) resistance over a period of seven years. The results show a significant increase of DA resistance in this relatively short period of time. In 1996, among the 39 isolates, 61.5% wer...
